    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.

    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.

    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).

    • A large number of disease agents has been recorded in geese and swans, viz. viruses, bacteria and unicellular parasites. • Some of these have the capacity to infect other bird species and mammals.

    • Geese and swans are highly mobile and often occur close to humans and in our agricultural landscape. As a consequence, they are sometimes suspected of  transmitting disease to livestock and humans

    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.

    Jämförelse av två enzyme-linked immunosorbent assays: mätning av diabetesspecifika autoantikroppar i en adult population2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    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.

    ‘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.

    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.

    Abstract [sv]

    Forskningsmiljön ”Man and Biosphere Health” är engruppering där forskare från helt olika biologiskakunskapsområden träffas och knyter kontakter. Forskning inom området ”Life Science” (Livsvetenskap), som framförallt innefattar biologi, medicin och biokemi, är världens största tvärdisciplinära forskningsområde med studier av biologisktliv samt de förutsättningar som utgör grunden för fortsatt liv. Unikt för samarbetet inom MABH är kombinationen avekologisk och biomedicinsk kompetens, vilket i vårt fall har inneburit att cellbiologisk forskning har knutits ihop med miljöforskning på ett nyskapande sätt.

    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.

    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.

    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.

    Genetic variation in the syntaxin-binding protein STXBP5 in type 1 von Willebrand disease patients2018In: Thrombosis and haemostasis, ISSN 2567-689X, Vol. 118, no 8, p. 1382-1389Article in journal (Refereed)
    Abstract [en]

    von Willebrand factor (VWF) levels in healthy individuals and in patients with type 1 von Willebrand disease (VWD) are influenced by genetic variation in several genes, for example, VWF, ABO and STXBP5. Here, we comprehensively screen for STXBP5 variants and investigate their association with type 1 VWD in Swedish patients and controls. The coding region of the STXBP5 gene was re-sequenced in 107 type 1 VWD patients and the detected variants were genotyped in the type 1 VWD population and a Swedish control population (464 individuals). The functional effects of missense alleles were predicted in silico and the pattern of genetic variation in STXBP5 was analysed. Re-sequencing of 107 type 1 VWD patients identified three missense and three synonymous variants in the coding sequence of STXBP5. The low-frequency missense variants rs144099092 (0.005) and rs148830578 (0.029) were predicted to be damaging, but were not accumulated in patients. No other rare candidate mutations were detected. STXBP5 showed a high level of linkage disequilibrium and a low overall nucleotide diversity of π = 3.2 × 10-4 indicating intolerance to variants affecting protein function. Three previously type 1 VWD-associated single nucleotide polymorphisms were located on one haplotype that showed an increased frequency in patients versus controls. No differences in messenger ribonucleic acid abundance among haplotypes could be found using Genotype-Tissue Expression project data. In conclusion, a haplotype containing the STXBP5 Asn436Ser (rs1039084) mutation is associated with type 1 VWD and no rare STXBP5 mutations contribute to type 1 VWD in the Swedish population.

    Genetic variation in the C-type lectin receptor CLEC4M in type 1 von Willebrand Disease patients2018In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 13, no 2Article in journal (Refereed)
    Abstract [en]

    von Willebrand factor (VWF) levels in healthy individuals and in patients with type 1 von Willebrand disease (VWD) are influenced by genetic variation in several genes, e.g. VWF, ABO, STXBP5 and CLEC4M. This study aims to screen comprehensively for CLEC4M variants and investigate their association with type 1 VWD in the Swedish population. In order to screen for CLEC4M variants, the CLEC4M gene region was re-sequenced and the polymorphic neck region was genotyped in 106 type 1 VWD patients from unrelated type 1 VWD families. Single nucleotide variants (SNV) and variable number tandem repeat (VNTR) allele and genotype frequencies were then compared with 294 individuals from the 1000Genomes project and 436 Swedish control individuals. Re-sequencing identified a total of 42 SNVs. Rare variants showed no accumulation in type 1 VWD patients and are not thought to contribute substantially to type 1 VWD. The only missense mutation (rs2277998, NP_001138379.1:p.Asp224Asn) had a higher frequency in type 1 VWD patients than in controls (4.9%). The VNTR genotypes 57 and 67 were observed at higher frequencies than expected in type 1 VWD patients (6.4% and 6.2%) and showed an increase in patients compared with controls (7.4% and 3.1%). Strong linkage disequilibrium in the CLEC4M region makes it difficult to distinguish between the effect of the missense mutation and the VNTR genotypes. In conclusion, heterozygous VNTR genotypes 57 and 67 of CLEC4M were highly enriched and are the most likely mechanism through which CLEC4M contributes to disease in the Swedish type 1 VWD population.

    Genetic variation in the von Willebrand factor gene in Swedish von Willebrand disease patients2018In: TH Open, ISSN 2512-9465, Vol. 2, no 1, p. 39-48Article in journal (Refereed)
    Abstract [en]

    von Willebrand factor (VWF) level and function are influenced by genetic variation in VWF and several other genes in von Willebrand disease type 1 (VWD1) patients. This study comprehensively screened for VWF variants and investigated the presence of ABO genotypes and common and rare VWF variants in Swedish VWD1 patients. The VWF gene was resequenced using Ion Torrent and Sanger sequencing in 126 index cases historically diagnosed with VWD. Exon 7 of the ABO gene was resequenced using Sanger sequencing. Multiplex ligation-dependent probe amplification analysis was used to investigate for copy number variants. Genotyping of 98 single nucleotide variants allowed allele frequency comparisons with public databases. Seven VWD2 mutations and 36 candidate VWD1 mutations (5 deletions, 4 nonsense, 21 missense, 1 splice, and 5 synonymous mutations) were identified. Nine mutations were found in more than one family and nine VWD1 index cases carried more than one candidate mutation. The T-allele of rs1063857 (c.2385T > C, p.Y795 = ) and blood group O were both frequent findings and contributed to disease in the Swedish VWD1 population. VWD2 mutations were found in 20 and candidate VWD1 mutations in 51 index cases out of 106 (48%). VWF mutations, a VWF haplotype, and blood group O all contributed to explain disease in Swedish VWD1 patients.

    Evaluation of Congo red staining in degenerating porcine photoreceptors in vitro: protective effects by structural and trophic support2018In: Journal of Histochemistry and Cytochemistry, ISSN 0022-1554, E-ISSN 1551-5044, Vol. 66, no 9Article in journal (Refereed)
    Abstract [en]

    Congo red (CR) is a histological stain used for the detection of extracellular amyloids mediating various neurodegenerative diseases. Given that damaged photoreceptors appear to degenerate similarly to other nerve cells, CR staining was evaluated in experimentally injured porcine retina. CR staining appeared mostly as discrete cytosolic deposits with no obvious plaque formation during the investigated time period. Increases of CR labeling coincided temporally with the known accumulation of mislocalized opsins and increases of cell death. Coculture, either with human retinal pigment epithelium (ARPE) or human neural progenitor (ReN) cells, was accompanied by a significant reduction of CR labeling. Of particular interest was the reduction of CR labeling in cone photoreceptors, which are important for the perception of color and fine details and afflicted in age-related macular degeneration (AMD). Electron microscopy revealed inclusions in the inner segment, cell body, and occasionally synaptic terminals of photoreceptor cells in cultured specimens. Closer examinations indicated the presence of different types of inclusions resembling protein aggregates as well as inclusion bodies. The current results indicate that injury-related response resulted in accumulation of CR deposits in photoreceptor cells, and that trophic and/or structural support attenuated this response.

    Long-distance and local movements of greylag geese in present-day agricultural landscapes2018In: 18th Conference of Goose Specialist Group: Conference Abstracts / [ed] Rasa Morkune, Modestas Bruzas, Julius Morkunas, Marine Institute of Klaipeda University , 2018, p. 77-Conference paper (Refereed)
    Abstract [en]

    Recent changes in environmental conditions together with increasing goose populations have completely changed the ballgame for geese in Europe. To better understand their current distribution and foraging patterns, this project will explore how geese utilize the agricultural landscape, with focus on their movements, field selection and foraging patterns. We fitted 199 Greylag geese with neck-collars and 64 with GPS transmitters at 5 locations in Sweden. The tagged geese will be used for studying movement patterns at a field-tofield level. However, the GPS transmitters also deliver data that can be used together with re-sightnings of neck-collared geese to unravel large-scale movement patterns of the Swedish Greylag goose population. Preliminary results from GPS positions received June--November 2017 indicate a varation in migration patterns and wintering grounds, depending on the origin of the geese. Geese breeding and molting in the southern parts of Sweden seem to migrate shorter distances, and have spent most of their time during the autumn months in Denmark, or in the southernmost parts of Sweden, while the geese marked farther north migrated earlier and moved longer distances, with the majority spending the autumn in Germany and the Netherlands.

    Changes in species richness and composition of boreal waterbird communities: a comparison between two time periods 25 years apart2019In: Scientific Reports, ISSN 2045-2322, E-ISSN 2045-2322, Vol. 9, no 1Article in journal (Refereed)
    Abstract [en]

    Global measures of biodiversity indicate consistent decline, but trends reported for local communitiesare more varied. Therefore, we need better understanding of mechanisms that drive changes in diversity of local communities and of differences in temporal trends between components of local diversity, such as species richness and species turnover rate. Freshwater ecosystems are vulnerable to multiple stressors, and severe impacts on their biodiversity have been documented. We studied species richness and composition of local boreal waterbird communities in 1990/1991 and 2016 at 58 lakes distributed over six regions in Finland and Sweden. The study lakes represented not only local trophic gradients but also a latitudinal gradient in the boreal biome. While species richness tended to be lower in 2016 than in 1990/1991, species turnover was relatively high. Within foraging guilds, local species richness of diving ducks and surface feeding waterbirds decreased, whereas that of large herbivores increased. The number of species gained in local communities was higher in lakes with rich vegetation than in lakes with sparse vegetation. Conservation of boreal freshwater ecosystems would benefit from recognizing  hat large-scale environmental changes can affect local diversity via processes operating atfiner scales.

    Forskningsanknuten grundutbildning: utbildningsanknuten forskning?2018In: Man and Biosphere Health: en komplett akademisk miljö / [ed] Ann-Sofi Rehnstam-Holm, Kristianstad: Högskolan Kristianstad , 2018, p. 8-15Chapter in book (Other academic)
    Abstract [sv]

    Begreppet forskningsanknuten utbildning kan definieras på ett flertal sätt. Idealt ska studenterna inom sin utbildning stöta på forskning genom att få kännedom om aktuell forskning och vara praktiskt involverade i forskningsprojekt. För att detta ska uppnås bör majoriteten av lärarna vara forskningsaktiva inom för utbildningen relevanta områden och att ett vetenskapligt förhållningssätt till kunskap förmedlar på bästa pedagogiska sätt också detta förankrat i forskning. I den här artikeln ger vi exempel på hur studenter har involverats i våra forskningsprojekt både på högskolan, på universitetssjukhuset i Lund och vid internationella universitet och forskningsstationer.

    A method of predicting the in vitro fibril formation propensity of Aβ40 mutants based on their inclusion body levels in E. coli2019In: Scientific Reports, ISSN 2045-2322, E-ISSN 2045-2322, Vol. 9, no 1Article in journal (Refereed)
    Abstract [en]

    Overexpression of recombinant proteins in bacteria may lead to their aggregation and deposition in inclusion bodies. Since the conformational properties of proteins in inclusion bodies exhibit many of the characteristics typical of amyloid fibrils. Based on these findings, we hypothesize that the rate at which proteins form amyloid fibrils may be predicted from their propensity to form inclusion bodies. To establish a method based on this concept, we first measured by SDS-PAGE and confocal microscopy the level of inclusion bodies in E. coli cells overexpressing the 40-residue amyloid-beta peptide, Aβ40, wild-type and 24 charge mutants. We then compared these results with a number of existing computational aggregation propensity predictors as well as the rates of aggregation measured in vitro for selected mutants. Our results show a strong correlation between the level of inclusion body formation and aggregation propensity, thus demonstrating the power of this approach and its value in identifying factors modulating aggregation kinetics.

    Simple, fast and inexpensive large "whole water" volume sample SPE-loading using compressed air and finely ground sand2019In: Analytical Methods, ISSN 1759-9660, E-ISSN 1759-9679, Vol. 11, no 7, p. 894-896Article in journal (Refereed)
    Abstract [en]

    In environmental trace analysis there is often a need to enrich the compounds of interest from a large sample volume, where the use of solid phase extraction (SPE) is more or less the standard technique. The presence of the sample matrix can cause clogging of the SPE-column, especially at the end of a sample load. Swedish surface waters are often humic rich making the use of traditional sample loading by a vacuum manifold very limited. This obstacle forced the development of a different sample loading technique, based on compressed air and sand as an in-line-filter, designed to load larger sample volumes as needed in trace level analysis of hormones in surface water. The developed technique, combined with a UPLC MS/MS method, showed promising reproducibility and accuracy, and enabled increased sensitivity for the analysis of hormones in humic rich surface water.

    High flow-rate sample loading in large volume whole water organic trace analysis using positive pressure and finely ground sand as a SPE-column in-line filter2019In: Molecules, ISSN 1420-3049, E-ISSN 1420-3049, Vol. 24, no 7, article id E1426Article in journal (Refereed)
    Abstract [en]

    By using an innovative, positive pressure sample loading technique in combination with an in-line filter of finely ground sand the bottleneck of solid phase extraction (SPE) can be reduced. Recently published work by us has shown the proof of concept of the technique. In this work, emphasis is put on the SPE flow rate and method validation for 26 compounds of emerging environmental concern, mainly from the 1st and 2nd EU Watch List, with various physicochemical properties. The mean absolute recoveries in % and relative standard deviations (RSD) in % for the investigated compounds from spiked pure water samples at the three investigated flow rates of 10, 20, and 40 mL/min were 63.2% (3.2%), 66.9% (3.3%), and 69.0% (4.0%), respectively. All three flow rates produced highly repeatable results, and this allowed a flow rate increase of up to 40 mL/min for a 200 mg, 6 mL, reversed phase SPE cartridge without compromising the recoveries. This figure is more than four times the maximum flow rate recommended by manufacturers. It was indicated that some compounds, especially pronounced for the investigated macrolide molecules, might suffer when long contact times with the sample glass bottle occurs. A reduced contact time somewhat decreases this complication. A very good repeatability also held true for experiments on both spiked matrix-rich pond water (high and low concentrations) and recipient waters (river and wastewater) applying 40 mL/min. This work has shown that, for a large number of compounds of widely differing physicochemical properties, there is a generous flow rate window from 10 to 40 mL/min where sample loading can be conducted. A sample volume of 0.5 L, which at the recommended maximum flow rate speed of 10 mL/min, would previously take 50 min, can now be processed in 12 min using a flow rate of 40 mL/min. This saves 38 min per processed sample. This low-cost technology allows the sample to be transferred to the SPE-column, closer to the sample location and by the person taking the sample. This further means that only the sample cartridge would need to be sent to the laboratory, instead of the whole water sample, like today's procedure.

    Effekter av utsättningar av farmade änder ämnade för jakt2018In: Man and Biosphere Health –: en komplett akademisk miljö / [ed] Rehnstam-Holm, A.-S., Kristianstad: Högskolan Kristianstad , 2018, p. 41-47Chapter in book (Other academic)
    Abstract [sv]

    I över 40 år har det i Sverige pågått ett storskaligt, ekologiskt experiment där hundratusentals gräsänder årligen har fötts upp i fångenskap och satts ut i våtmarker för att öka på den jaktbara populationen. Genom uppfödning i fångenskap riskerar man att de farmade gräsänderna blir annorlunda gentemot de vilda. För att studera effekterna på den vilda populationen av dessa utsättningar startades 2010 ett doktorandprojekt finansierat av Naturvårdsverket. Projektet kom fram till att farmade änder skiljer sig i beteende och utseende mot de vilda. Det går även att genetiskt skilja på farmade och vilda gräsänder. Ett nytt projekt startades 2017 för att vidare studera effekter av utsättningar, nu även på miljön och den biologiska mångfalden där änderna sätts ut. Projekten om effekter av utsättningar av farmade änder involverar forskare från olika lärosäten i Sverige, men också från flera olika europeiska länder. Ett nära samarbete med olika lokala privata aktörer som uppfödare, markägare, jägare och viltmästare samt större organisationer somViltmästareförbundet och Svenska Jägareförbundet är avgörande för projektens framgång. Att kommuniceraresultaten på så väl vetenskapliga konferenser som för icke akademiker involverade i projekten samt i undervisning på Högskolan Kristianstad och på gymnasieskolor har hela tiden varit en målsättning. Projekten har också en tydlig plats i forskningsmiljön MABH vars kompetenser inom t.ex. vattenvård, sjukdomsspridning och landskapsutnyttjande kanknytas till projekten.

    Large-scale releases of native species: the mallard as a predictive model system2015Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Human alteration of natural systems, and its consequences are of great concern and the impact on global ecosystems is one of the biggest threats that biodiversity stands before. Translocations of invasive species, as well as intraspecific contingents with non-native genotypes, whether they are deliberate or unintentional, are one such alteration and its consequences are continuously being assessed. The mallard (Anas platyrhynchos) is the most numerous and widespread duck in the world and a flagship in wetland conservation. It is also an important game species which is heavily restocked for hunting purposes, especially in Europe where over three million ducklings are released every year. Because of its hunted status, its abundance, and the number of released individuals, it can serve as a model species to study effects of releases, both for conservation and restocking for hunting, on wild populations. In this thesis the status of the mallard was assessed in the Nordic countries and the effects of releases on the wild populations were studied by mining historical ringing data, comparing morphology of present-day wild, farmed, and historical mallards, and analyzing phylogeography of wild and farmed mallards in Europe. The status of the mallard population in the Nordic countries are generally good, however, a joint effort of European countries is needed to monitor and manage the population. A significant difference between wild and farmed mallards concerning longevity, migration, bill morphology and genetic structure was also found, together with signs of cryptic introgression of farmed genotypes in the wild population with potential fitness reduction as a result. The effect is however limited by that only a fraction of released farmed mallards reach the breeding season due to low survival. A natural captive environment is crucial to keep individuals wild-like with high survival rates after release. However, with an introgression of potentially maladapted farmed genotypes leading to a reduction in fitness, a low survival of released mallards would favor the wild population. A legislative change regarding obligation to report numbers, provenance, and release sites of farmed mallard should be considered, together with practical solutions of ringing and genetic monitoring of released mallards.
