    Development of a solid phase extraction method for the simultaneous determination of steroid hormones in H295R cell line using liquid chromatography–tandem mass spectrometry2013In: Journal of chromatography. B, ISSN 1570-0232, E-ISSN 1873-376X, Vol. 935, no September, p. 61-69Article in journal (Refereed)
    Abstract [en]

    The H295R in vitro cell line produces the majority of the steroidogenesis, for which reason it is commonly used as a screening tool for endocrine disrupting chemicals. Simultaneous determination of the precursor cholesterol and key steroid hormones could give a broad insight into the mechanistic disruption of the steroidogenesis. Steroid hormones have primarily been extracted from H295R incubation medium by means of liquid-liquid extraction (LLE) and the obtained recoveries and matrix effects have typically not been stated or assessed. In the present study a solid-phase extraction (SPE) method was developed and validated for the simultaneous extraction of cholesterol and five key steroid hormones pregnenolone, 17-hydroxyprogesterone, testosterone, cortisol and aldosterone from H295R incubation medium, and finally detected by LC-MS/MS. Cholesterol was recovered at a level of 55.7%, while steroid hormone recoveries ranged from 98.2 to 109.4%. Matrix effects varied between -0.6% and 62.8%. Intra-day precision was deemed acceptable, but the inter-day precision for pregnenolone and aldosterone exceeded the precision limit of 15% RSD. Although LLE has been the most frequently used extraction method in H295R studies, however, our investigation has shown that SPE may relatively easily extract and recover steroid hormones, potentially replacing LLE.

    Simultaneous determination of endogenous steroid hormones in human and animal plasma and serum by liquid or gas chromatography coupled to tandem mass spectrometry2013In: Journal of chromatography. B, ISSN 1570-0232, E-ISSN 1873-376X, Vol. 928, no June, p. 59-77Article in journal (Refereed)
    Abstract [en]

    Analytical methodologies based on liquid or gas chromatography coupled to tandem mass spectrometry for the simultaneous determination of two or more endogenous steroid hormones in human and animal plasma and serum has received increased attention the last few years. Especially in the clinical setting steroid profiling is of major importance in disease diagnostics. This paper discusses recent findings in such multi-steroid hormone procedures published from 2001 to 2012. The aim was to elucidate possible relationships between chosen analytical technique and the obtained analyte sensitivity for endogenous steroid hormones. By evaluating the success, at which the currently applied techniques have been utilized, more general knowledge on the field is provided. Furthermore the evaluation provides directions in which future studies may be interesting to conduct.

    Incorporation of (14)C-cholesterol in human adrenal corticocarcinoma H295R cell line and online-radiodetection of produced (14)C-steroid hormone metabolites2017In: Journal of Pharmaceutical and Biomedical Analysis, ISSN 0731-7085, E-ISSN 1873-264X, Vol. 145, p. 569-575Article in journal (Refereed)
    Abstract [en]

    This study demonstrates the addition of (14)C-cholesterol to the human cell line H295R will in-situ form radiolabeled steroid hormones allowing for new mechanistic and metabolic insights. The aim of the present study was to in-situ radiolabel steroid hormones from cell line-incorporated (14)C-cholesterol using the OECD guideline 456, H295R steroidogenesis in-vitro assay. Radiodetection of the steroid metabolites of the steroidogenic pathway allows for an improved understanding of the various enzymatic mechanisms involved without necessarily being dependent on quantification. Generated radiolabeled steroids were analyzed using HPLC hyphenated with a Flow Scintillation Analyzer (FSA). H295R cells were incubated with radiolabeled cholesterol and cell media were collected and prepared by solid phase extraction and analyzed with HPLC-FSA. For successful radiolabeling of the steroids in the steroidogenesis of H295R cells, radioactive cholesterol may potentially only need to be added just before the cells are incubated for 72h in well plates. Based on the obtained HPLC-FSA chromatograms, and confirmation of the observations by studies in the literature, a qualitative time profile for the production of steroid hormones was estimated. Multiple radiolabeled steroid hormones were identified by means of analytical standards and UV (ultraviolet) co-chromatography, though the elucidation of multiple metabolites remains unresolved. Although online radiodetection proved to suffer from suboptimal sensitivity, the concept of radiolabeling the steroidogenesis in H295R cells with (14)C-cholesterol and detecting the radiolabeled steroid hormones online was proved and may assist in further toxicological studies.

    Hypotheses and tracking results about the longest migration: the case of the arctic tern2019In: Ecology and Evolution, ISSN 2045-7758, E-ISSN 2045-7758Article in journal (Refereed)
    Abstract [en]

    The arctic tern Sterna paradisaea completes the longest known annual return migration on Earth, traveling between breeding sites in the northern arctic and temperate regions and survival/molt areas in the Antarctic pack‐ice zone. Salomonsen (1967, Biologiske Meddelelser, Copenhagen Danske Videnskabernes Selskab24, 1) put forward a hypothetical comprehensive interpretation of this global migration pattern, suggesting food distribution, wind patterns, sea ice distribution, and molt habits as key ecological and evolutionary determinants. We used light‐level geolocators to record 12 annual journeys by eight individuals of arctic terns breeding in the Baltic Sea. Migration cycles were evaluated in light of Salomonsen's hypotheses and compared with results from geolocator studies of arctic tern populations from Greenland, Netherlands, and Alaska. The Baltic terns completed a 50,000 km annual migration circuit, exploiting ocean regions of high productivity in the North Atlantic, Benguela Current, and the Indian Ocean between southern Africa and Australia (sometimes including the Tasman Sea). They arrived about 1 November in the Antarctic zone at far easterly longitudes (in one case even at the Ross Sea) subsequently moving westward across 120–220 degrees of longitude toward the Weddell Sea region. They departed from here in mid‐March on a fast spring migration up the Atlantic Ocean. The geolocator data revealed unexpected segregation in time and space between tern populations in the same flyway. Terns from the Baltic and Netherlands traveled earlier and to significantly more easterly longitudes in the Indian Ocean and Antarctic zone than terns from Greenland. We suggest an adaptive explanation for this pattern. The global migration system of the arctic tern offers an extraordinary possibility to understand adaptive values and constraints in complex pelagic life cycles, as determined by environmental conditions (marine productivity, wind patterns, low‐pressure trajectories, pack‐ice distribution), inherent factors (flight performance, molt, flocking), and effects of predation/piracy and competition.

    Occurrence of ionophores in the Danish environment2014In: Antibiotics, ISSN 2079-6382, Vol. 3, no 4, p. 564-571Article in journal (Refereed)
    Abstract [en]

    Antibiotics in the environment are a potential threat to environmental ecosystems as well as human health and safety. Antibiotics are designed to have a biological effect at low doses, and the low levels detected in the environment have turned focus on the need for more research on environmental occurrence and fate, to assess the risk and requirement for future regulation. This article describes the first occurrence study of the antibiotic polyether ionophores (lasalocid, monensin, narasin, and salinomycin) in the Danish environment. Various environmental matrices (river water, sediment, and soil) have been evaluated during two different sampling campaigns carried out in July 2011 and October 2012 in an agricultural area of Zealand, Denmark. Lasalocid was not detected in any of the samples. Monensin was measured at a concentration up to 20 ng·L−1 in river water and 13 µg·kg−1 dry weight in the sediment as well as being the most frequently detected ionophore in the soil samples with concentrations up to 8 µg·kg−1 dry weight. Narasin was measured in sediment samples at 2 µg·kg−1 dry weight and in soil between 1 and 18 µg·kg−1 dry weight. Salinomycin was detected in a single soil sample at a concentration of 30 µg·kg−1 dry weight.

    Quantification of four ionophores in soil, sediment and manure using pressurised liquid extraction2013In: Journal of Chromatography A, ISSN 0021-9673, E-ISSN 1873-3778, Vol. 1307, no September, p. 27-33Article in journal (Refereed)
    Abstract [en]

    A multi-residue pressurised liquid extraction (PLE) methodology has been established for the determination of the four ionophores: lasalocid, monensin, salinomycin and narasin in solid environmental matrices. The PLE methodology is combined with solid phase extraction as clean-up using liquid chromatography coupled to tandem mass spectrometry applying electrospray ionisation for detection. The samples were freeze-dried prior to extraction. The absolute recoveries for soil and sediment ranged from 71 to 123% (relative standard deviation (RSDs) below 16%) and in the range 94–133% (RSDs 9–35%) for poultry manure. The final method allowed for the detection of four ionophores down to a few hundred ng kg−1 in natural solid matrices with limit of quantifications (LOQs) being 0.96, 0.87, 0.98, and 0.64 μg kg−1 in soil for lasalocid, monensin, salinomycin, and narasin, respectively. Corresponding LOQs in sediment were 1.28, 1.34, 1.39, and 0.78 μg kg−1 for the respective ionophores, while in manure the LOQs were 0.98, 1.01, 1.45, and 1.01 μg kg−1.

    Developing a new research tool for use in free-ranging cetaceans: recovering cortisol from harbour porpoise skin2015In: Conservation Physiology, E-ISSN 2051-1434, Vol. 3Article in journal (Refereed)
    Abstract [en]

    We developed a chemical analytical procedure for sampling, extracting and determining epidermal skin cortisol concentrations (SCCs) in the harbour porpoise (Phocoena phocoena) using gas chromatography–tandem mass spectrometry. In brief, this involved a pressurized liquid extraction with a two-step solid-phase clean-up. A derivatization step was conducted prior to detection. To evaluate the new assay, cortisol was analysed in three different sample types obtained from four harbour porpoises: skin plates, dorsal fin skin plugs (with and without lidocaine) and epidermal scrapes. Skin cortisol concentrations could be measured using the new assay in the majority of the tested skin samples down to a minimal sample size of 49 mg dry weight (dw). Water content ranged from 10 to 46% in the plug samples, which had SCCs from 2.1 to 77.7 ng/g dw. Epidermal scrape samples had the highest water content (83–87%) and lower SCCs (0.6–15 ng/g dw), while the skin plates had intermediate water contents (60–66%) and SCCs of 2.6–13.0 ng/g dw. SCC was slightly higher in plugs with lidocaine than without (average values of 41 and 33 ng/g dw, respectively). Substantial within-individual variations in cortisol concentrations are also common in other matrices such as blood and hair. Some important factors behind this variation could be e.g. the animal's sex, age, body condition, reproductive stage, and the body region sampled, as well as season, moulting cycles and water temperature. Clearly, more research into SCCs is required. The findings described here represent the first critical steps towards using epidermal skin cell samples to assess chronic stress levels in cetaceans and the development of a widely applicable health-assessment tool in these species.

    Phobos LIFE (Living Interplanetary Flight Experiment).2019In: Astrobiology, ISSN 1531-1074, E-ISSN 1557-8070Article in journal (Refereed)
    Abstract [en]

    The Planetary Society's Phobos Living Interplanetary Flight Experiment (Phobos LIFE) flew in the sample return capsule of the Russian Federal Space Agency's Phobos Grunt mission and was to have been a test of one aspect of the hypothesis that life can move between nearby planets within ejected rocks. Although the Phobos Grunt mission failed, we present here the scientific and engineering design and motivation of the Phobos LIFE experiment to assist with the scientific and engineering design of similar future experiments. Phobos LIFE flew selected organisms in a simulated meteoroid. The 34-month voyage would have been the first such test to occur in the high-radiation environment outside the protection of Earth's magnetosphere for more than a few days. The patented Phobos LIFE "biomodule" is an 88 g cylinder consisting of a titanium outer shell, several types of redundant seals, and 31 individual Delrin sample containers. Phobos LIFE contained 10 different organisms, representing all three domains of life, and one soil sample. The organisms are all very well characterized, most with sequenced genomes. Most are extremophiles, and most have flown in low Earth orbit. Upon return from space, the health and characteristics of organisms were to have been compared with controls that remained on Earth and have not yet been opened.

    Attenuation of pharmaceutical substances: phytoremediation using constructed wetlands2018In: 13th Society of wetland scientists (SWS) Europe chapter meeting: management of wetland ecosystem services: issues, challenges and solutions, 2018, p. 19-22Conference paper (Refereed)
    Abstract [en]

    Introduction: Currently, wastewater treatment plants (WWTPs) do not efficiently remove pharmaceutical substances (PS). Thus, such substances are now frequently found in aquatic ecosystems worldwide. Also, concentrations of some PS in treated effluents exceed Environmental Quality Standards proposed by EU legislation. One resource-efficient option for increasing PS removal in WWTP effluents is to use constructed wetlands (CWs) as an attenuation step (Breitholtz et al. 2012; Li et al. 2014). However, very little research has been done on how to maximize the PS attenuation capacity of CWs. Therefore, a project with the aim to investigate reduction of different pharmaceutical substances in CWs with different vegetation compositions and water depths, was performed at the Experimental Wetland Area (EVA) located 20 km north of Halmstad, Sweden.

    Abiotic degradation of antibiotic ionophores2013In: Environmental Pollution, ISSN 0269-7491, E-ISSN 1873-6424, Vol. 182, p. 177-183Article in journal (Refereed)
    Abstract [en]

    Hydrolytic and photolytic degradation were investigated for the ionophore antibiotics lasalocid, monensin, salinomycin, and narasin. The hydrolysis study was carried out by dissolving the ionophores in solutions of pH 4, 7, and 9, followed by incubation at three temperatures of 6, 22, and 28 °C for maximum 34 days. Using LC–MS/MS for chemical analysis, lasalocid was not found to hydrolyse in any of the tested environments. Monensin, salinomycin, and narasin were all stable in neutral or alkaline solution but hydrolysed in the solution with a pH of 4. Half-lives at 25 °C were calculated to be 13, 0.6, and 0.7 days for monensin, salinomycin, and narasin, respectively. Absorbance spectra from each compound indicated that only lasalocid is degraded by photolysis (half-life below 1 h) due to an absorbance maximum around 303 nm, and monensin, salinomycin, and narasin are resistant to direct photolysis because they absorb light of environmentally irrelevant wavelengths.

    On the road to 'research municipalities': analysing transdisciplinarity in municipal ecosystem services and adaptation planning2018In: Sustainability Science, ISSN 1862-4065, E-ISSN 1862-4057, Vol. 13, no 3, p. 765-784Article in journal (Refereed)
    Abstract [en]

    Transdisciplinary research and collaboration is widely acknowledged as a critical success factor for solution-oriented approaches that can tackle complex sustainability challenges, such as biodiversity loss, pollution, and climate-related hazards. In this context, city governments' engagement in transdisciplinarity is generally seen as a key condition for societal transformation towards sustainability. However, empirical evidence is rare. This paper presents a self-assessment of a joint research project on ecosystem services and climate adaptation planning (ECOSIMP) undertaken by four universities and seven Swedish municipalities. We apply a set of design principles and guiding questions for transdisciplinary sustainability projects and, on this basis, identify key aspects for supporting university-municipality collaboration. We show that: (1) selecting the number and type of project stakeholders requires more explicit consideration of the purpose of societal actors' participation; (2) concrete, interim benefits for participating practitioners and organisations need to be continuously discussed; (3) promoting the 'inter', i.e., interdisciplinary and inter-city learning, can support transdisciplinarity and, ultimately, urban sustainability and long-term change. In this context, we found that design principles for transdisciplinarity have the potential to (4) mitigate project shortcomings, even when transdisciplinarity is not an explicit aim, and (5) address differences and allow new voices to be heard. We propose additional guiding questions to address shortcomings and inspire reflexivity in transdisciplinary projects.

    Analytical sample preparation strategies for the determination of antimalarial drugs in human whole blood, plasma and urine2014In: Journal of chromatography. B, ISSN 1570-0232, E-ISSN 1873-376X, Vol. 962, p. 109-131Article in journal (Refereed)
    Abstract [en]

    Antimalarial drugs commonly referred to as antimalarials, include a variety of compounds with different physicochemical properties. There is a lack of information on antimalarial distribution in the body over time after administration, e.g. the drug concentrations in whole blood, plasma, and urine, which must be improved in order to advance curing the parasitic disease malaria. A key problem also lies in that pharmacokinetic studies not always are performed in patient groups that may benefit most of the treatment such as children, pregnancy and lower-weight ethnic populations. Here we review the available sample preparation strategies combined with liquid chromatographic (LC) analysis to determine antimalarials in whole blood, plasma and urine published over the last decade. Sample preparation can be done by protein precipitation, solid-phase extraction, liquid-liquid extraction or dilution. After LC separation, the preferred detection tool is tandem mass spectrometry (MS/MS) but other detection methods have been used e.g. UV, fluorescence and electrochemical detection. Major trends for sample preparation of the different groups of antimalarials for each matrix and its detection have been summarized. Finally, the main problems that the researchers have dealt with are highlighted. This information will aid analytical chemists in the development of novel methods for determining existing antimalarials and upcoming new drugs

    Crafting next generation eco-label policy2018In: Environmental Law, Vol. 48, no 3, p. 409-452Article in journal (Other academic)
    Abstract [en]

    Eco-labels present a promising policy tool in the effort to achieve sustainable consumption. Many questions remain, however, about the extent to which eco-labels can contribute to sustainability efforts and how to maximize their effectiveness. This Article deploys research from evolutionary psychology, behavioral law and economics, and norm theory to offer specific insights for the design and implementation of eco-labels to enhance their influence on sustainable consumer choice. Notably, this research suggests possibilities for ecolabels to shape or expand consumer preferences for green goods, and thereby enhance eco-label influence on consumer behavior by extending it beyond eco-minded consumers. We suggest that public exposure of the label (so that people see it) and the exposure of the purchasing behavior (so that other people can see that you have bought the product) are key elements to the success of eco-labels—the social context around product purchasing may be as important as the ecolabel itself. We recommend that behavioral insights be used to improve eco-labeling as traditionally understood by incorporating knowledge about behavioral tendencies into label design so as to allow for more accurate matching of consumers’ preexisting environmental preferences to eco-labeled goods, and develop next-generation ecolabeling policy with the potential to significantly expand the market for eco-labeled goods. Specifically, 1) Eco-labels could be purposefully designed and implemented to attract consumers motivated by social norms; 2) Eco-labels could appeal to a wider range of abstract norm alternate more broadly or locally accepted and strong abstract that are stronger and/or more broadly accepted or locally-salient; and 3) Ecolabels could highlight private, near and near-term benefits.

    A comparative ultrastructure study of storage cells in the eutardigrade Richtersius coronifer in the hydrated state and after desiccation and heating stress2018In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 13, no 8Article in journal (Refereed)
    Abstract [en]

    Tardigrades represent an invertebrate phylum with no circulatory or respiratory system.Their body cavity is filled with free storage cells of the coelomocyte-type, which are responsible for important physiological functions. We report a study comparing the ultrastructure of storage cells in anhydrobiotic and hydrated specimens of the eutardigrade Richtersius coronifer. We also analysed the effect of temperature stress on storage cell structure. Firstly, we verified two types of ultrastructurally different storage cells, which differ in cellular organelle complexity, amount and content of reserve material and connection to oogenetic stage. Type I cells were found to differ ultrastructurally depending on the oogenetic stage of the animal. The main function of these cells is energy storage. Storage cells of Type I were also observed in the single male that was found among the analysed specimens. The second cell type, Type II, found only in females, represents young undifferentiated cells, possibly stem cells. The two types of cells also differ with respect to the presence of nucleolar vacuoles,which are related to oogenetic stages and to changes in nucleolic activity during oogenesis. Secondly, this study revealed that storage cells are not ultrastructurally affected by six months of desiccation or by heating following this desiccation period. However, heating of the desiccated animals (tuns) tended to reduce animal survival, indicating that longterm desiccation makes these animals more vulnerable to heat stress. We confirmed the degradative pathways during the rehydration process after desiccation and heat stress. Our study is the first to document two ultrastructurally different types of storage cells in tardigrades and reveals new perspectives for further studies of tardigrade storage cells.

    Evaluation of extraction methods for quantitative analysis of tardigrade populations in soil and leaf litter2018In: Pedobiologia, ISSN 0031-4056, E-ISSN 1873-1511, Vol. 70, p. 1-5Article in journal (Refereed)
    Abstract [en]

    Accurate quantitative analysis of soil tardigrades depends on a relevant extraction method. Over the years, a number of different methods have been used, but the efficiency of these methods has rarely been evaluated for soil and leaf litter tardigrades. Four methods of extraction were compared in this study: the light-cooling (L-C) extractor, the high-gradient (H-G), Baermann extractor, the non-gradient (N-G) Baermann extractor and sieves.The results indicate that light and temperature are significant factors influencing tardigrade extraction. The L-C and H-G extractors were more effective than sieves for all substrate categories. These extraction methods (L-C and H-G) therefore seem to be appropriate for quantitative studies of soil and leaf litter tardigrades.

    Bidrar gäss och svanar  till övergödning av våtmarker?2018In: Fakta för förvaltare: gäss och svanar: kunskapssammanställning om bete, övergödning, smittspridning och skyddsjakt / [ed] Johan Elmberg & Johan Månsson, Stockholm: Naturvårdsverket , 2018, p. 33-47Chapter in book (Other academic)
    Abstract [en]

    • Swans and geese occur in larger numbers near more people than ever before, in Sweden as well as in Western Europe.

    • Increasing populations sometimes lead to problems and conflicts. On agricultural land geese and swans can cause costly damage to growing crops. Intense grazing by these birds may also affect natural vegetation, sometimes leading to conflict with conservation and biodiversity goals.

    • Geese and swans are obligate herbivores, consuming leaves, stems, seeds and root parts of terrestrial and aquatic plants.

    • Grazing on growing crops may cause conflicts of interest also when geese and swans congregate in large numbers in wetlands adjacent to cropland.

    • Geese and swans provide a multitude of ecosystem services, for example viewing, hunting, meat, and eco-tourism revenues. GEESE AND SWANS AS VECTORS OF NUTRIENTS

    • Geese and swans eat large amounts of plant material, have a relatively inefficient digestive system, and produce a lot of droppings.

    • These birds find most of their food on land, but spend a large part of the day  resting on wetlands, where they also defecate.

    • In autumn, winter and spring most geese and swans make daily flights between feeding and roost sites, thereby becoming vectors of nutrients to wetlands and lakes

    Can wetlands reduce humic substances in forested streams: combining two approaches to characterize efficiency2018In: Book of abstracts: Linnaeus ECO-TECH '18, 2018Chapter in book (Other academic)
    Abstract [en]

    Establishing statistical significance in assessing wetland performance can be quite challenging when reduction in the monitored substance is very small and temporarily variable. Assessing colour changes associated with humic substances is such a situation. One of the most important parameters of any evaluation of wetland treatment performances is the retention time of the water before it exit the wetland. This can be theoretically estimated, but even better measured directly with the help of a tracing agent. In this research, the approach is based on the simultaneously assessment of hydraulic retention time using conservative tracing (Rhodamine WT) and a mass balance based removal efficiency assessment (regression slope of the summation mass-in vs. summation mass-out).

    Population change in breeding boreal waterbirds in a 25‐year perspective: what characterises winners and losers?2019In: Freshwater Biology, ISSN 0046-5070, E-ISSN 1365-2427Article in journal (Refereed)
    Abstract [en]
    1. Understanding drivers of variation and trends in biodiversity change is a general scientific challenge, but also crucial for conservation and management. Previous research shows that patterns of increase and decrease are not always consistent at different spatial scales, calling for approaches combining the latter. We here explore the idea that functional traits of species may help explaining divergent population trends.
    2. Complementing a previous community level study, we here analyse data about breeding waterbirds on 58 wetlands in boreal Fennoscandia, covering gradients in latitude as well as trophic status. We used linear mixed models to address how change in local abundance over 25 years in 25 waterbird species are associated with life history traits, diet, distribution, breeding phenology, and habitat affinity.
    3. Mean abundance increased in 10 species from 1990/1991 to 2016, whereas it decreased in 15 species. Local population increases were associated with species that are early breeders and have small clutches, an affinity for luxurious wetlands, an herbivorous diet, and a wide breeding range rather than a southern distribution. Local decreases, by contrast, were associated with species having large clutches and invertivorous diet, as well as being late breeders and less confined to luxurious wetlands. The three species occurring on the highest number of wetlands all decreased in mean abundance.
    4. The fact that early breeders have done better than late fits well with previous research about adaptability to climate change, that is, response to earlier springs. We found only limited support for the idea that life history traits are good predictors of wetland level population change. Instead, diet turned out to be a strong candidate for an important driver of population change, as supported by a general decrease of invertivores and a concomitant increase of large herbivores.
    5. In a wider perspective, future research needs to address whether population growth of large‐bodied aquatic herbivores affects abundance of co‐occurring invertivorous species, and if so, if this is due to habitat alteration, or to interference or exploitative competition.

    Fakta för förvaltare: gäss och svanar: kunskapssammanställning om bete, övergödning, smittspridning och skyddsjakt2018Collection (editor) (Other academic)
    Abstract [sv]

    GÄSSEN I SVERIGE blir allt fler. De flesta gåsarter ökar i antal och med växande populationer ökar också konflikterna mellan samhällsintressen och människor som berörs av gässen. Ändrade flyttningsmönster är ett annat exempel på hur  förutsättningarna för förvaltningen av gäss och svanar påverkas. I den strategi för svensk viltförvaltning som Naturvårdsverket har tagit fram betonas en förvaltning byggd på kvalitetssäkrad kunskap och förvaltningen av gäss är ett bra exempel på vikten av aktuell kunskap när omständigheterna förändras. Viltstrategin beskriver de vägval som Naturvårdsverket avser att genomföra för att utveckla och stärka Sveriges viltförvaltning fram till år 2020. Bland annat ska arbetet med att förebygga skador och andra problem som vilt orsakar utvecklas, tillsammans med övriga berörda organisationer. Strategin betonar också att svensk viltförvaltning ska bygga på den bästa tillgängliga kunskapen och att Naturvårdsverket har ett stort ansvar för att se till att aktuell kunskap kommer till användning. Forskarna Johan Elmberg och Johan Månsson har på uppdrag av Naturvårdsverkets vetenskapliga kommitté för viltforskning gjort en litteraturöversikt om befintlig kunskap om gäss och om framtida kunskapsbehov. Kunskapssammanställningen ligger också till grund för ett större gåsforskningsprojekt under ledning av Johan Elmberg och Johan Månsson, med start 2017. I Naturvårdsverkets arbete med att ta fram vetenskapligt underlag till stöd för viltförvaltningen är gåsprojektet en viktig pusselbit som är tänkt att under de kommande åren kunna ge ytterligare kunskap till en gåsförvaltning i förändring. Författarna svarar ensamma för rapportens innehåll, slutsatser och rekommendationer

    Abstract [en]

    Swans and geese occur in larger numbers near more people than ever before,  in Sweden as well as in Western Europe.

    • Increasing populations sometimes lead to problems and conflicts. On agricultural land geese and swans can cause costly damage to growing crops. Intense grazing by these birds may also affect natural vegetation, sometimes leading to conflict with conservation and biodiversity goals.

    • Geese and swans are obligate herbivores, consuming leaves, stems, seeds and root parts of terrestrial and aquatic  plants.

    • Grazing on growing crops may cause conflicts of interest also when geese and swans congregate in large numbers in wetlands adjacent to  cropland.

    • Geese and swans provide a multitude of ecosystem services, for example viewing, hunting, meat, and eco-tourism revenues.

    GEESE AND SWANS AS   HERBIVORES

    • As their diet is very rich in fibres and water, geese and swans must consume large amounts of plant material in order to obtain enough nutrients (mainly proteins and carbohydrates).

    • Geese and swans have a highly developed capability to assess the nutrient compo- sition of different species and parts of plants. This is true for proteins and easily digestible carbohydrates, and also for components that are hard to digest or unpala- table. As a consequence, these birds are very selective feeders, if given a   choice.

    • Nutrient needs vary over the year; in autumn and spring relatively more proteins are consumed, whilst plants rich in energy are favoured in winter.

    • In general, agricultural crops contain more nutrients than the natural food plants of geese and swans. As a result, feeding on agricultural land is almost always marter choice’ for them.

    Abstract [en]

    Type- 1 diabetes (T1D) is an autoimmune disease with insulin deficiency caused by degradation of insulin- producing betacells in pancreas. Four different autoantibodies that target beta- cell specific antigenes have been identified: insulinautoantibodies (IAA), glutamic acid decarboxylase antibodies (GADA), islet antigen2-antibodies (IA-2A) and antibodies against zinktransporter 8 (ZnT8A). In this study, a comparison between 2screen islet cell autoantibody ELISA-kit (RSR, Cardiff, UK) coated with GAD65/IA-2 and 3screen islet cell autoantibody ELISA- kit (RSR, Cardiff, UK) coated with GAD65/IA-2/ZnT8, was performed to investigate whether results from these two kits provide comparable sensitivity and specificity in an adult population of new onset patients with T1D and healthy adults. RSR 2screen obtained 1 % higher specificity (98 %) in comparison to RSR 3screen (97 %) on the same sensitivity (92 %) and is recommended primarily for screening of autoantibodies in a population of adult patients at increased risk for T1D and healthy adults blood donors.

    Beyond Scatter-Hoarding and Frugivory: European Corvids as Overlooked Vectors for a Broad Range of Plants2019In: Frontiers in Ecology and Evolution, E-ISSN 2296-701X, Vol. 7, article id 133Article in journal (Refereed)
    Abstract [en]

    It is well-known that some members of the crow family (Corvidae) are important for seed dispersal either via frugivory (e.g., when feeding on berries) or by scatter hoarding (e.g., of nuts). Dispersal via gut passage of seeds within a fleshy fruit can be considered "classical endozoochory." However, corvids are rarely recognized as vectors of plants lacking a fleshy fruit, or a large nut (such as plants with a dry achene, capsule or caryopsis). Dispersal of such seeds via gut passage can be considered "non-classical endozoochory." A century ago, Heintze (1917a,b); Heintze (1918) reported on extensive field studies of seed dispersal by 11 species of European Corvidae. His work is overlooked in contemporary reviews of corvid biology. We resurrect his work, which suggests that contemporary views about seed dispersal by corvids are too narrow. Heintze identified 157 plant taxa from 42 families which were dispersed by corvids by endozoochory, as well as another nine taxa only dispersed by synzoochory (which includes scatter-hoarding). Most (54%) of the plant species dispersed by endozoochory lack a fleshy fruit and have previously been assigned to other dispersal syndromes, mainly associated with wind (10%), self-dispersal (22%) or epizoochory (18%). Plants lacking a fleshy fruit were particularly well-represented from the Caryophyllaceae (12 species), Poaceae (14 species), and Polygonaceae (8 species). Of 27 taxa germinated by Heintze from seeds extracted from corvid pellets or feces (71% of those tested), 20 lack a fleshy fruit. Similarly, of 32 taxa he recorded as seedlings having germinated from pellets in the field, 11 lacked a fleshy fruit. However, Heintze's quantitative data show that classical endozoochory is dominant in Magpies Pica pica and Hooded Crows Corvus cornix, for which 97% of seeds dispersed were fleshy-fruited. Corvids overlap with waterfowl as vectors of terrestrial plants dispersed by non-classical endozoochory, and 56 species are dispersed by both corvids and dabbling ducks according to the lists of Heintze and Soons et al. (2016). Finally, Heintze's data show that corvids were already dispersing alien plants in Europe a century ago, such as the North American Dwarf Serviceberry Amelanchier spicata.

    ‘Rage against the machine’?: the opportunities and risks concerning the automation of urban green infrastructure2018In: Landscape and Urban Planning, ISSN 0169-2046, E-ISSN 1872-6062, Vol. 180, p. 85-92Article in journal (Refereed)
    Abstract [en]

    Contemporary society is increasingly impacted by automation; however, few studies have considered the potential consequences of automation on ecosystems and their management (hereafter the automation of urbangreen infrastructure or UGI). This Perspective Essay takes up this discussion by asking how a digital approach to UGI planning and management mediates the configuration and development of UGI and to whose benefit? This is done through a review of key issues and trends in digital approaches to UGI planning and management. We first conceptualize automation from a social, ecological, and technological interactions perspective and use this lens to present an overview of the risks and opportunities of UGI automation with respect to selected case studies. Results of this analysis are used to develop a conceptual framework for the assessment of the material and governance implications of automated UGIs. We find that, within any given perspective, the automation of UGI entails a complex dialectic between efficiency, human agency and empowerment. Further, risks and opportunities associated with UGI automation are not fixed but are dynamic properties of changing contextual tensions concerning power, actors, rules of the game and discourse at multiple scales. We conclude the paper by outlining a research agenda on how to consider different digital advances within a social-ecological-technological approach.

    Impact of animal manure separation technologies on steriod hormone distribution: consequences for agricultural practices2014Conference paper (Refereed)
    Abstract [en]

    When steroid hormones are emitted into the environment, they may have harmful effects on the reproduction system of aquatic life. Until now, research has primarily focused on human excretion, demonstrating that steroid hormones reach the aquatic environment due to insufficient removal in waste water treatment processes. However more recently, it has been revealed that agricultural practices also may add to the environmental burden of steroid hormones. So far, research activities have mainly focused on steroid estrogens, but also androgens, progestagens and glucocorticoids, expressed in the vertebrate steroidogenesis, may occur at substantial levels in animal manure and should be addressed. In agricultural practices the animal manure can be applied to the soil as raw manure, but also as a solid or liquid manure fraction, since current livestock production facilities utilizes a recently developed technology, which separates raw animal manure into a solid and a liquid fraction.This technology offers an improved handling and refined distribution of the manure nutrients to the farmlands and the possibility to reduce the environmental impact of manure nutrients, especially avoiding the surplus load of phosphorous. In the present work we investigated the distribution of 9 steroid hormones (pregnenolone, progesterone, dehydroepiandrosterone, androstenedione, testosterone, dihydrotestosterone, estrone, 17α-estradiol and 17β-estradiol) in raw manure and manure separates from 10 to 15 different pig farms in Denmark utilizing 4 different separation technologies. Furthermore, we investigated a possible relationship between the steroid hormone concentration and the different manure fractions and separation technologies. The chemical steroid hormone analysis was done by inverse and integrated clean-up pressurized liquid extraction, and further cleaned by a two step solid-phase extraction before derivatization and finally analyzed by GC-MS/MS.It was found that the steroid hormones were predominant in the solid manure separate calling for manure management strategies to reduce the content of steroid hormones in separated manure solid fraction. This could potentially be achieved through composting or anaerobic digestion for biogas production of the solid fraction; however, the effects of these technologies on steroid hormones need to be verified.

    Animal manure separation technologies diminish the environmental burden of steroid hormones2015In: Environmental Science and Technology Letters, E-ISSN 2328-8930, Vol. 2, no 4, p. 133-137Article in journal (Refereed)
    Abstract [en]

    Newly developed treatment technologies are capable of separating livestock manure into a liquid fraction and a solid fraction using sedimentation, mechanical, and/or chemical methods. These technologies offer a potential means of distributing nutrients to agricultural lands without the unwanted environmental risks associated with the release of steroid hormones to adjacent waterways. To assess the potential benefit of these technologies in reducing the level of release of steroid hormones to adjacent waterways, distribution profiles of nine steroid hormones (pregnenolone, progesterone, dehydroepiandrosterone, androstenedione, testosterone, dihydrotestosterone, estrone, 17α-estradiol, and 17β-estradiol) were determined in raw swine manure, and in solid and liquid fractions separated from ten full-scale manure separation systems. Steroid hormone concentrations, normalized for nitrogen content, were significantly higher in separated solids than in liquids. If separated liquids are applied instead of raw manure, steroid hormone loading can be reduced by a factor of 2 at a constant nitrogen fertilization level.

    Klimatförändringarna försämrar immunförsvaret hos kräftor, musslor och sjöstjärnor, och gör att de lättare får infektioner. De smittsamma bakterierna och virusen ser däremot inte ut att fara illa i den förändrade miljön. En dålig kombination för ekosystemet, och för oss konsumenter av marina skaldjur.

    Kan klimatförändringen öka smitta av infektionssjukdomar via havsvatten?2018In: Man and Biosphere Health: en komplett akademisk miljö / [ed] Ann-Sofi Rehnstam Holm, Kristianstad: Högskolan Kristianstad , 2018, p. 22-33Chapter in book (Other academic)
    Abstract [sv]

    De pågående klimatförändringarna gör haven allt varmare ochsurare. Dessutom förväntas perioder av intensiva regn att öka, v et bidrar till högre koncentrationer av näringsämnen i havsvattnet. Även sjukdomsframkallande bakterier och virus följer med vattnet från land ut i havet. Näringsämnena kommer att göda algblomningarna, vilket resulterar i fler syrefria bottnar. I bottensedimenten finns det naturligt rikligt med metallen mangan. Den frisätts till vattnet vid syrebrist och kan då tas upp av bottenlevande djur. I spåren av detta har vi genom experimentella långtidsstudier sett negativa effekter på immunförsvaret hos både kräfta, mussla och sjöstjärna. Förmågan att eliminera inkräktande bakterier och virus försämrades och djuren blev mer infektionsbenägna. Den tydligaste effekten såg vi då vi tillsatte mangan. Vi undersöker även hur viabilitet och virulens hos sjukdomsalstrande bakterier i havet påverkas och har bl.a. sett att havslevande bakterier av släktet Vibrio inte far illa av de förändrade faktorerna i havet, vilket indikerar att de kan få ett övertag på demarina organismerna, vars immunförsvar försvagats.

    Long-term rearing affects pheromone-mediated flight behaviour of the Indian meal moth, Plodia interpunctella2019In: Journal of applied entomology, ISSN 0931-2048, E-ISSN 1439-0418Article in journal (Refereed)
    Abstract [en]

    The pest Plodia interpunctella (Hubner) is reared in many research laboratories. In a culture established in 1996, attraction of males to the female-produced sex pheromone in flight tunnel assays gradually decreased after approximate to 15 years of rearing. A new culture was established to enable comparison with the old culture regarding traits associated with mate finding. Female calling activity, pheromone titre and male antennal response to pheromone components did not differ between cultures. In contrast, very few males from the old culture reached the pheromone source in flight tunnel assays compared with 61%-81% of males from the other culture. Our results highlight the importance of maintaining viable insect cultures for research purposes and suggest frequent evaluation of traits involved in chemical communication in such cultures to ensure reliable results in experiments.

    Sustainable management of migratory European ducks: finding model species2018In: Wildlife Biology, ISSN 0909-6396, E-ISSN 1903-220XArticle in journal (Refereed)
    Abstract [en]

    Eurasian migratory duck species represent a natural resource shared between European countries. As is evident throughout human harvest history, lack of coordinated management and monitoring at appropriate levels often leads to ‘the tragedy of the commons’, where shared populations suffer overexploitation. Effective management can also be hampered by poor understanding of the factors that limit and regulate migratory populations throughout their flyways, and over time. Following decades of population increase, some European duck populations now show signs of levelling off or even decline, underlining the need for more active and effective management. In Europe, the existing mechanisms for delivering effective management of duck populations are limited, despite the need and enthusiasm for establishing adaptive management (AM) schemes for wildlife populations. Existing international legal agreements already oblige European countries to sustainably manage migratory waterbirds. Although the lack of coordinated demographic and hunting data remains a challenge to sustainable management planning, AM provides a robust decision-making framework even in the presence of uncertainty regarding demographic and other information. In this paper we investigate the research and monitoring needs in Europe to successfully apply AM to ducks, and search for possible model species, focusing on freshwater species (in contrast to sea duck species) in the East Atlantic flyway. Based on current knowledge, we suggest that common teal Anas crecca, Eurasian wigeon Mareca penelope and common goldeneye Bucephala clangula represent the best species for testing the application of an AM modelling approach to duck populations in Europe. Applying AM to huntable species with relatively good population data as models for broader implementation represents a cost effect to develop AM on a European flyway scale for ducks, and potentially other waterbirds in the future.

    Sustainable management of migratory European ducks: finding model species2018Conference paper (Other academic)
    Abstract [en]

    Eurasian migratory ducks are a natural resource shared between multiple European countries. Due to lack of flyway-level management and monitoring, there is a risk of “the tragedy of the commons” arising, where populations are overexploited. Effective management may also be hindered by a poor understanding of the factors that limit and regulate migratory populations throughout their flyways, and over time. Following decades of population increase, some European duck populations now show signs of levelling off or even decline, underlining the need for more active management. In Europe, we lack effective common tools to manage duck populations, despite the need and enthusiasm for establishing flyway-level adaptive management (AM) schemes for migratory birds. There are several international legal agreements (e.g. EEC Birds Directive, AEWA) that oblige European countries to sustainably manage migratory birds and their habitats. Although the lack of coordinated demographic and hunting data remains a challenge to sustainable management planning for waterfowl, AM provides a robust decision-making framework even in the presence of uncertainty.

    We investigate the research and monitoring needs in Europe to successfully apply AM to ducks, and search for possible model species, focusing on freshwater duck species.  Our geographical focus is NW Europe (excluding Russia), the area utilized by ducks in the East-Atlantic flyway. Based on current knowledge and their wide distribution, we suggest that Common Teal Anas crecca, Eurasian Wigeon Mareca penelopeand Common Goldeneye Bucephala clangulawould be the best species for testing the application of an AM modelling approach for ducks in Europe. Applying AM to huntable species with relatively good population data as models for broader implementation represents a cost effective way of starting to develop AM on a European flyway scale for ducks and other harvested waterbirds.

    Fungi-based treatment of real brewery waste streams and its effects on water quality2019In: Bioprocess and biosystems engineering (Print), ISSN 1615-7591, E-ISSN 1615-7605, Vol. 42, no 8, p. 1317-1324Article in journal (Refereed)
    Abstract [en]

    Nutrient-rich liquid waste streams generated during the beer brewing were treated by submerged fungal growth. Among five filamentous fungal strains tested, Pleurotus ostreatus and Trichoderma harzianum were selected for treatment of run-off from spent grain and hot trub, respectively. In both waste streams, nitrogen was well removed by fungal treatment, with a maximum reduction of 91.5 ± 0.5% of total nitrogen in run-off from spent grain treated with P. ostreatus and 77.0 ± 3.1% in hot trub treated with T. harzianum. Removal of phosphorus was considerably lower, with maximum removal of total phosphorus of 30.8 ± 11.1% for the P. ostreatus treatment and 16.6 ± 7.8% for the T. harzianum treatment. Considering the high concentration of phosphorus in the waste sources (320-600 mg L-1), additional techniques for its removal are needed. In the P. ostreatus treatment, a total amount of 13.2 ± 2.2 g L-1 dwt of biomass with a protein concentration of 11.6 ± 2.1% was produced.

    Effects of fungal-assisted algal harvesting through biopellet formation on pesticides in water2018In: Biodegradation, ISSN 0923-9820, E-ISSN 1572-9729, Vol. 29, no 6, p. 557-565Article in journal (Refereed)
    Abstract [en]

    Recent research has demonstrated the potential of using filamentous fungi to form pellets with microalgae (biopellets), in order to facilitate harvesting of microalgae from water following algae-based treatment of wastewater. In parallel, there is a need to develop techniques for removing organic pollutants such as pesticides and pharmaceuticals from wastewater. In experiments using the microalga Chlorella vulgaris, the filamentous fungus Aspergillus niger and biopellets composed of these microorganisms, this study investigated whether fungal-assisted algal harvesting can also remove pesticides from contaminated water. A mixture of 38 pesticides was tested and the concentrations of 17 of these were found to be reduced significantly in the biopellet treatment, compared with the control. After harvesting, the concentration of total pesticides in the algal treatment did not differ significantly from that in the control. However, in the fungal treatment and biopellet treatment, the concentration was significantly lower (59.6 ± 2.0 µg/L and 56.1 ± 2.8 µg/L, respectively) than in the control (66.6 ± 1.0 µg/L). Thus fungal-assisted algal harvesting through biopellet formation can also provide scope for removing organic pollutants from wastewater, with removal mainly being performed by the fungus.

    Redefining education about food traditions in Swedish home economics education: report from a lesson study2018In: “What is happening in home economics?”: a spotlight on European activities / [ed] EAHE, 2018Conference paper (Other academic)
    Abstract [en]

    The syllabus for Home Economics in Sweden has a concrete culture perspective tied to cultural variations and food traditions (Skolverket 2011, 2016). Culture has been described as pivotal to how we socially understand the world around us (Burr 2003, Gerger 2009), which means that the world isn’t neutral to us but rather understood from one cultural perspective or another (Hastrup 2004). Research (Bohm 2016, Höijer 2013) has illustrated how food selected to be included in Home Economics education primarily is chosen by the teacher, and also that the teacher is embedded in the cultural and structural traditions that are (re)constructed in society and school. Education about food in Home Economics is contested in the sense that students and teachers’ cultural perspective are misaligned and students’ experiences rarely are taken as a starting point (Höijer 2013). So far there has been no research investigating how education about food traditions is realized, but experience suggests that it often entails baking traditional saffron buns in December or to speak about geographical regions rather than to investigate food as codes, images, values, experiences and ways of thinking that groups of people share. The main aim of the project was to develop Home Economic teachers competence in a Swedish municipality, the specific aim was to develop education about food traditions.

    Between August of 2017 and January 2018 a competence development project was carried out in a large municipality near Stockholm. The project was planned as a combination between lectures and research in the form of a lesson study (Lewis 2002; Lewis, Perry & Murata 2006; Murata 2011). In the lesson study a specific lesson was planned by the whole group and carried out by one teacher, and observed by other teachers. Analysis and revision of the lesson was done by the whole group.

    Radiation tolerance in tardigrades: current knowledge and potential applications in medicine2019In: Cancers, ISSN 2072-6694, Vol. 11, no 9, article id 1333Article, review/survey (Refereed)
    Abstract [en]

    Tardigrades represent a phylum of very small aquatic animals in which many species have evolved adaptations to survive under extreme environmental conditions, such as desiccation and freezing. Studies on several species have documented that tardigrades also belong to the most radiation-tolerant animals on Earth. This paper gives an overview of our current knowledge on radiation tolerance of tardigrades, with respect to dose-responses, developmental stages, and different radiation sources. The molecular mechanisms behind radiation tolerance in tardigrades are still largely unknown, but omics studies suggest that both mechanisms related to the avoidance of DNA damage and mechanisms of DNA repair are involved. The potential of tardigrades to provide knowledge of importance for medical sciences has long been recognized, but it is not until recently that more apparent evidence of such potential has appeared. Recent studies show that stress-related tardigrade genes may be transfected to human cells and provide increased tolerance to osmotic stress and ionizing radiation. With the recent sequencing of the tardigrade genome, more studies applying tardigrade omics to relevant aspects of human medicine are expected. In particular, the cancer research field has potential to learn from studies on tardigrades about molecular mechanisms evolved to maintain genome integrity.

    Cell biology of the tardigrades: current knowledge and perspectives2019In: Evo-Devo: Non-model species in cell and developmental biology / [ed] Tworzydlo W., Bilinski S., Cham: Springer, 2019, p. 231-249Chapter in book (Other academic)
    Abstract [en]

    The invertebrate phylum Tardigrada has received much attention for containing species adapted to the most challenging environmental conditions where an ability to survive complete desiccation or freezing in a cryptobiotic state is necessary for persistence. Although research on tardigrades has a long history, the last decade has seen a dramatic increase in molecular biological (“omics”) studies, most of them with the aim to reveal the biochemical mechanisms behind desiccation tolerance of tardigrades. Several other aspects of tardigrade cell biology have been studied, and we review some of them, including karyology, embryology, the role of storage cells, and the question of whether tardigrades are eutelic animals. We also review some of the theories about how anhydrobiotic organisms are able to maintain cell integrity under dry conditions, and our current knowledge on the role of vitrification and DNA protection and repair. Many aspects of tardigrade stress tolerance have relevance for human medicine, and the first transfers of tardigrade stress genes to human cells have now appeared. We expect this field to develop rapidly in the coming years, as more genomic information becomes available. However, many basic cell biological aspects remain to be investigated, such as immunology, cell cycle kinetics, cell metabolism, and culturing of tardigrade cells. Such development will be necessary to allow tardigrades to move from a nonmodel organism position to a true model organism with interesting associations with the current models C. elegans and D. melanogaster.

    Environmental adaptations: radiation tolerance2019In: Water bears: the biology of tardigrades / [ed] Ralph O Schill, Springer, 2019, p. 311-330Chapter in book (Other academic)
    Abstract [en]

    Several studies in different species have documented that tardigrades are among the most radiation-tolerant animals on Earth, surviving doses of ionizing radiation on the order of kGy. Both low-LET and high-LET radiation have been used with no apparent differences in the tolerance of the animals. Tolerance to ionizing radiation in tardigrades also seems to be independent of whether the animal has entered a dry anhydrobiotic state or is hydrated with normal activity. However, when exposed to UV radiation, desiccated tardigrades show a higher tolerance than hydrated animals. Recent studies in several species have shown that tardigrade embryos have considerably lower tolerance to ionizing radiation compared to adults, and embryos in the early stage of development are clearly more sensitive to radiation than those in the late developmental stage. The molecular mechanisms behind radiation tolerance in tardigrades are still largely unclear, but available evidence suggests that mechanisms related to both the avoidance of DNA damage and the repair of damage are involved.

    Nitrogen uptake potential under different temperature-salinity conditions: implications for nitrogen cycling under climate change scenarios2018In: Marine Environmental Research, ISSN 0141-1136, E-ISSN 1879-0291, Vol. 141, p. 196-204Article in journal (Refereed)
    Abstract [en]

    As projected by climate change models, increase in sea surface temperature and precipitation in the future may alter nutrient cycling in the coastal regions due to potential changes in phytoplankton community structure and their ability to assimilate nitrogen (N) and carbon (C). An experiment simulating different temperature and salinity conditions (28°C-35 ambient conditions, 28ºC-31, 31ºC-35 and 31ºC-31) in mesocosms containing 1000 L of coastal water from the Arabian Sea was performed and N uptake rates were measured using 15N tracer technique on 2nd, 5th, 7th and 10th day of the experiment. The results show that, under all conditions, the total N (NO3- + NH4+) uptake rates were lower in the beginning and on the final day of the tracer experiment, while it peaked during middle, consistent with chlorophyll a concentrations. Total N uptake rate was significantly lower (p = 0.003) under ambient temperature-lower salinity condition (28ºC-31) than the others. This indicates that lowering of salinity in coastal regions due to excessive rainfall in the future may affect the N uptake potential of the phytoplankton, which may change the regional C and N budget.
