    Stigande havsnivåers påverkan på kulturmiljöer och naturtyper: En studie längs Skånes kust och i Vellinge kommun2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Stora klimatförändringar sker just nu globalt, en konsekvens av dessa förändringar är stigande havsnivåer längs kusterna. En förhöjd havsnivå kan utgöra ett hot mot lågt liggande miljöer och andra värden i anslutning till kusten. I Sverige har ingen tidigare studie gjorts på hur kulturmiljöer och naturtyper påverkas av klimatförändringar så som stigande havsnivåer. Syftet med denna studie är att undersöka i vilken utsträckning kulturmiljöer och naturtyper längs Skånes kust kommer att påverkas av stigande havsnivåer på 1 m, 2 m och 3 m. Resultatet av den extensiva studien längs Skånes kust visar att det är flest kulturmiljöer som påverkas vid en förändrad havsnivå på 1 m i Vellinge och Lomma kommun, då 41 st respektive 15 st lämningar kommer att påverkas. De naturtyper som påverkas i störst omfattning längs Skånes kust är glasörtstränder, salta strandängar och strandängar vid Östersjön. Detaljstudien i Vellinge kommun visar att Riksantikvarieämbetets värderingsplattform är svår att applicera på kulturmiljöer utan lämpar sig bättre att applicera på enskilda objekt eftersom plattformens värderingsmall är för abstrakt för att identifiera och täcka in alla värden som en kulturmiljö omfattar. Länsstyrelsen i Västra Götalands åtgärdsförslag går att tillämpa olika bra beroende på kulturmiljön och vilka objekt den utgör. Även här är det lättare att tillämpa åtgärdsförslagen beroende på enskilda objekt, snarare än en hel kulturmiljö. Åtgärdsförslagen är svåra att applicera på naturtyper eftersom de flesta åtgärderna skulle skapa en barriär för växt- och djurlivet.

    Cata - a former homeland village affected by Betterment, Eastern Cape, South Africa2005Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [en]

    This study focus on the house ruins and land use in Nyokana, a former village section in Cata, by looking at their location, number and the people who lived there and their living before the Betterment plan was carried through. This is done by studying an old map and documents of Cata, field studies with GPS-using and by interviewing mostly old inhabitants. The result is a basis for the development of the planned tourism track within the heritage project, wich runs by BRC and University of Fort Hare.

    Skyddszoner som fosforfällor: En studie om skyddszonernas förmåga att förhindra fosforläckage2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Phosphorus leaking from our fertilized arable land contributes to eutrophication of lakes and seas and travels among other things, with particles from fertilized soil. Straightening of rivers and ditching helps drained water travel quickly from the arable land lakes and seas. To avoid phosphorus leaking there are buffer zones that are placed between the field and the streams with the purpose of captivating the phosphorus. One previous study has shown that a risk occurs for phosphorus saturation on the lands adjacent to the streams (Borggaard, Moberg & Sibbesen 1991; Vought et al 1994; Svanbäck et al 2013).   

      

    This thesis aims to see if today’s buffer zones are saturated or can take up more phosphorus and if the difference in the type of soil matter to the result. The effects of pH and organic matter on the phosphorus content are also examined. The soils clay, moraine  and sand are studied in this thesis. The work also aims to demonstrate the changes in the landscape and history of the buffer zones.  

      

    Soil samples were collected from 15 buffer zones around Kristianstad. The samples were dried, sieved and then shaken with water containing a known amount of phosphorus. Uptake of phosphorus was then measured. Historical and contemporary maps were also studied to see the landscape change.  

      

    The analysis showed that nine out of fifteen zones were saturate. The three soil types each had three saturated zones and two unsaturated and the difference was not significant between the soil types. For the soil clay results showed that pH and organic matter content influenced the amount of phosphorus in which, a higher pH, showed a higher phosphorus content and the higher organic matter reviled a lower amount if phosphorus. For moraine results showed same as in clay but the relation between the organic matter and how it affected the phosphorus content was not significant. The result for the sand was that higher pH in the soil resulted to higher phosphorus content. The same effect was seen for the organic matter in sand which means that the phosphorus content rises with higher organic matter.   

    The buffer zones that we studied occur mostly on land that has been used as arable land for at least 100 years, while others have previously been used as wet- or other meadows or pastures. The areas that have been arable lands a long time have probably been fertilized heavily during the postwar period. Establishing buffer zones may therefore have contributed to recreate the landscape as it was before the rationalization of agriculture in the late 1950s. Buffer zones prevent erosion and help to preserve biodiversity both in the stream and buffer zone. Today's eligible zones may only be grassed but one could imagine future protection zones with salix / tree where the phosphorus is removed through the wood.

    Hydroarkeologi på Västgötaslätten: en kartstudie av sambandet mellan fornlämningar och förhistorisk hydrologi.2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This bachelor thesis investigates hydroarchelogy through several studies of maps, ancient remains and their relationship to the hydrology of the prehistoric landscape in a selected area in Sweden where a prehistoric hydrological situation has been recreated. The focus of this thesis is remains which are located over 1 000 meters from a body of water today, but which have water within 1 000 meters on historical maps.

     

    Ancient remains are generally situated relatively close to the present bodies of water and among the studied remains the dominating types are graves and tools. The majority of the remains date back to the prehistory and between the 18th century and today the land use surrounding the remains has consisted of an increasing part of open field. The water has changed both by natural and antropogen causes and the major antropogen changes started around 1800. The studied area probably has a totally different hydrological appearance today compared to during the prehistory.

    High-dosage treatment of a Quebec stream with Bacillus thuringiensis serovar. israelensis: efficacy against black fly larvae (Diptera, Simuliidae) and impact on nontarget insects1985In: Canadian Entomologist, ISSN 0008-347X, E-ISSN 1918-3240, Vol. 117, no 12, p. 1523-1534Article in journal (Refereed)
    Abstract [en]

    A typical lake outlet of the Canadian Shield was treated for 15 min with a high dose (5.28 g/L s−1 of discharge) of Teknar®, a commercial formulation of Bacillus thuringiensis serovar. israelensis. Efficacy on Simuliidae larvae and impact on non-target aquatic insects of this stream were monitored using drift nets, counting plates, and artificial turf substrates along a 1000-m section downstream of the site of application. Compared with a 4-day pre-treatment average for 12-h sampling periods, drift of Simuliidae increased from 64 to 92 ×, with shorter peaks of 133–184 ×, 2–6 h after treatment. There was no evident drift increase in larvae of Ephemeroptera, Plecoptera, Trichoptera, Chironomidae, or dipterous pupae, but larvae of Blephariceridae (Diptera) were severely affected as their drift was increased by up to 50 × and remained high for 3 days. After 30 h the mortality of Simuliidae on counting plates ranged from 95 to 82% in the first 300 m, with detachment rates of 78.5–46.5%. Densities of non-target insect larvae were not reduced on the artificial substrates, except for 2 genera of Chironomidae (Eukiefferella and Polypedilum) which were reduced 26 to 39% of their original density. Drifting larvae of 1 chironomid genus (Phaenopsectra) also showed symptoms of toxemia by B.t.i. The main impact of the treatment was thus seen in 2 Nematocera families (Chironomidae and Blephariceridae) which were mainly exposed to B.t.i. sedimented on the bottom of the stream or attached to periphyton growing on rocks.

    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.

    Från ett nödvändigt ont, till en naturtyp värd att bevara - en studie av ljungheden i Sandsjöbacka och Grönabur/From a necessary evil to a nature type worth protect - a studie of the Calluna heath of Sandsjöbacka & Grönabur2005Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    In the middle of the 19th century was Calluna heath the major nature type in Halland, but the remaining parts today is only 1 500 hectares which is a 99 % decrease of the Calluna heath mainly due to an increase in forest plantations and arable fields. I have made a quantitative study how the Calluna heath of Grönabur & Sandsjöbacka has changed between 1841 and 2005 and why it didn’t disappear in the same manner, as it did in other parts of Halland.

    The studying of original sources as historical maps, literature and by doing field visits has been significant for the final result. The main reason for the different development of the Calluna heath in the investigation area (69 % decrease), compare to elsewhere in Halland, is the establishment and management of a nature reserve.

    People in nature: relational discourse for outdoor educators2014In: Research in Outdoor Education, ISSN 2375-6381, Vol. 12, no 1, p. 1-14Article in journal (Other academic)
    Abstract [en]

    Outdoor educators are concerned about a perceived human disconnection from nature. There is awareness of a lack of human affiliation, connection, or identity with nonhuman nature and its impact on attitudes and behaviors. This essay raises the possibility that despite our concern, we may contribute toward this disconnection via language that supports a separation of the natural and the cultural. Our ability to separate ourselves conceptually from the rest of nature may be partially to blame for environmental degradation, therefore challenging the nature-culture dichotomy is both useful and constructive. This essay will present examples of how outdoor educators can attempt to get past this problematic dichotomy and motivate more relational discourse within the practice of outdoor education.

    Upplevelsen av biologisk mångfald2015In: Vattenriket i Fokus, ISSN 1653-9338, Vol. 2015, no 4, p. 39-43Article in journal (Other (popular science, discussion, etc.))
    Abstract [en]

    It is important to do something outside, not only inside this building...if you are outside the nature is talking to you. (Arabic/English speaking visitor)

    Concern for a diminished nature experience has been referred to as an extinction of experience (Pyle, 1993). The concern is based on the fear that diminished experience of nature leads to reduced environmental awareness and knowledge, and ultimately, to a reduction in pro-environmental behavior. Attention to both the value and potential loss of nature experience is at the foundation of the research presented here.

     

    Two related studies are briefly presented that explore the experience of nature, and specifically, the experience of biodiversity in the Kristianstad Vattenrike biosphere reserve. The first is a study of the relationship between place attachment and participation in nature based outdoor recreation. Random and targeted field based surveys with residents of the Kristianstad municipality were used to gather information. Results indicated a positive and significant relationship between measures of place attachment and nature-based outdoor recreation. The second study, an investigation of the Swedish EPA mandated goal that Swedish Nature Centers (Naturum) will inspire or motivate a direct experience of nature was conducted using thought listing methods. The results of these interviews indicated that the nature center in the Kristianstad Vattenrike is serving this noted function. An outcome that links both studies are the results that highlight the importance of proximate access (in regard to residence and transportation) of recreation and outdoor opportunity to facilitate direct experiences of nature.

    Topophilia and human affiliation with nature2015Conference paper (Refereed)
    Abstract [en]

    Objective: The objective of this study is to explore the co-evolutionary foundation for place-based human affiliation with nonhuman nature, and its potential to support sustainable development at the local level. In particular, we analyse the Topophilia Hypothesis, an expansion of the Biophilia Hypothesis which includes also non-living elements in the environment.

    Methods: The study represents a multidisciplinary conceptual analysis of how biological selection and cultural learning may have interacted during human evolution to promote adaptive mechanisms for human affiliation with nonhuman nature via specific place attachment. 

    Results and Conclusions: The Biophilia Hypothesis has been one of the most important theories of human connectedness with nature, suggesting a genetically based inclination for human affiliation with the biological world. The Topophilia Hypothesis has extended the ideas of Biophilia to incorporate a broader conception of nonhuman nature and a co-evolutionary theory of genetic response and cultural learning. It also puts more emphasis on affiliation processes with the local environment. We propose that nurturing potential topophilic tendencies may be a useful method to promote sustainable development at the local level, and ultimately at the global level. Tendencies of local affiliation may also have implications for multifunctional landscape management, an important area within sustainability research, and we provide some examples of successful landscape management with a strong component of local engagement. Since human affiliation with nonhuman nature is considered an important dimension of environmental concern and support for pro-environmental attitudes, the Topophilia Hypothesis may provide a fruitful ground for a discourse within which scholars from many scientific fields, including human evolution and humanistic geography, can participate.

    Perceptions of the ecosystem services concept: opportunities and challenges in the Swedish municipal context2016In: Ecosystem Services, ISSN 2212-0416, E-ISSN 2212-0416, Vol. 17, p. 123-130Article in journal (Refereed)
    Abstract [en]

    A current focus of ecosystem services (ES) implementation is on the municipal level of government where international and national legislation and policies have to be translated into practice. Given this focus, an understanding of perceptions within municipalities of the ES concept is crucial to support the implementation process. Against this background, this paper examines the perceptions of Swedish municipal stakeholders for the ES concept. A 2013 Swedish federal mandate that states that the values of ecosystem services should be considered in relevant decision-making processes, provides a timely context. Current perceptions, preconditions and awareness are explored via interviews and analyses. The results show that the views on the ecosystem services concept and its usefulness are generally very positive. Conceptual knowledge use is perceived as important as is the recognition of monetary valuation of ES. However, clarification of the distinction between implicit and explicit use of the concept by stakeholders is needed. Finally, results indicate that a deeper understanding of monetary valuation of ecosystem services by municipal staff members is connected with a more critical view on monetary valuation. It is concluded that detailed and clear definitions and guidelines are needed in order to support the process of implementing ES in municipalities.

    Nature to place: rethinking the environmental connectedness perspective2014In: Journal of Environmental Psychology, ISSN 0272-4944, E-ISSN 1522-9610, Vol. 40, no December, p. 198-205Article in journal (Refereed)
    Abstract [en]

    The environmental connectedness perspective posits that direct encounter with generalized, or non-specific “nature,” leads to environmental connectedness and subsequent pro-environmental behavior. This article examines this perspective and proposes a place-based application of the nature encounter-environmental behavior relation. An empirical study using data from a national survey on outdoor recreation and nature-based tourism is presented. Results show a minimal relationship between measures of environmental connectedness and self-reports of environmental behavior. The following examination of the environmental connectedness perspective reveals that environmental connectedness is rooted in a material/objective perspective, neglecting the human domain of perceptions, values, and representations. The environment as “nature” is portrayed as a geographically undefined agent with the inherent power to change human attitudes and behavior. Based on this, the article concludes with a proposed replacement of the elusive concept of nature for the relational concept of place.

    Abstract [sv]

    This rapport handles the presence of two kinds of watermills in the Swedish landscape. The first is a small type with a horizontal shovel blade and the other a bigger kind with a vertical standing shovel scoop. The rapport seeks for information of their capacity and how long they existed as flour producing units. A important issue is how small can a brook be and still run a mill. Finally the reasons for their disappearance in one selected parish is shown.

    Rening av oljeförorenat vatten med torvabsorbent2007Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Hässleholms Renhållare AB är ett avfallsbolag som innehar en oljebehandlingsanläggning på deras centrala avfallsanläggning i Vankiva. På oljebehandlingsanläggningen tar de emot slam från oljeavskiljare och bilvårdsanläggningar samt i mindre mängd förorenade massor. Från behandlingsanläggningen utgår det en vattenfas som leds via ett avloppssystem vidare till det lokala behandlingssystemet för lakvattnet.

    I bolagets tillstånd för Vankiva avfallsanläggning har det föreskrivits att varje delflöde till den lokala behandlingen av lakvattnet måste kontrolleras för att inte fastställda gränsvärden för olja och tungmetaller ska överskridas.

    Under våren 2006 kompletterades avloppssystemet från oljebehandlingsanläggningen till lakvattenbehandlingen med en filterbrunn. Filterbrunnen innehåller en torvabsorbent som suger upp olja och tungmetaller från vattenfasen. Genom att reducera olja och tungmetaller från vattenfasen kommer bolaget att minska en stor källa av föroreningar till deras lokala behandlingssystem för lakvatten.

    Rapportens mål var att undersöka filtermaterialets reningsförmåga på vattenfasen från oljebehandlingsanläggning dels vid laborativa försök och dels vid fältundersökning.

    De laborativa försöken bestod av ett urlakningstest och en studie på filtermaterialets absorptionskapacitet. Resultat från urlakningstestet visar att torvsorbenten släpper mangan och järn i större mängd och sänker urlakningsvätskans pH. Resultat från filtermaterialets absorptionskapacitet visar att materialet effektivt adsorberar undersökta metaller. Ett utläckage av arsenik sker från filtermaterialet. För olja och dess biprodukter sker en mindre reduktion.

    Fältförsöket visar att filtret reducerar metallkoncentrationen i utgående vattenfas men absorption av olja uteblir vid hög belastning. Lakvattnet får tillskott av metalljoner från vattenfasen av aluminium, koppar, järn, mangan, nickel, bly och zink, då metallkoncentrationen är högre för vattenfasen än för lakvattnet.

    Kontroll av basflödet, som har ett konstant mindre flöde igenom filterbrunnen, visar resultat på låga metallkoncentrationer i ingående basflöde, som består av vatten från området tvätthall och avloppsvatten från kontoret. När basflödet passerar filterbrunnen urlakas arsenik, kvicksilver, nickel och zink från adsorberade metalljoner i filtermaterialet.

    Vid fältstudien visar resultaten på att filterbrunnen fungerade som en buffert. Filtermaterialet sorberade föroreningar i ingående vattenfas från oljeplattan och släppte metaller när basflödet passerade filterbrunnen. Detta kan medföra att det inte blir några stötbelastningar till lakvattnet av befintliga föroreningar från vattenfasen men tungmetaller kommer för eller senare ut i behandlingssystemet för lakvattnet.

    Hörneborg - borg eller lada?: kolanalys, magnetisk susceptibilitet, sjösänkning och historiska kartor.2013Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Hörneborg ligger på en udde i sjön Hörnsjön i Olofströms kommun i Blekinge län. En utgrävning av borgen gjordes 1997 för att fastställa funktion och ålder. 14C dateringar visade att borgen var byggd cirka 1030-1250 e.Kr. och förstördes genom brand någon gång mellan 1290 och 1420 e. Kr. (Ödman 1997). Enligt historiska kartor är Hörneborg placerad på en ö. Dokument över sänkning av vattennivån i sjön saknas. Förslag till utdikning av utloppet från Hörnsjön finns dock och syftet var att torrlägga omkringliggande marker vid Hörnsjön. Syftet med detta arbete är att sammanställa den litteratur som finns om Hörneborg, tidfästa sänkningen av Hörnsjöns yta och undersöka om det går att korrelera händelser i borgens historia med förändringar i sjösediment från Hörnsjön.

    Prover på bottensediment togs i tre profiler från isen på den östra sidan om borgen. Detta för att analysera kol och magnetiska mineral i sedimentet för korrelation med borgens historia. Borgens byggnation och förstörelse verkar inte ha gett några spår i sedimenten. Därför antas att materialet till byggnaden tagits från omgivningen, att byggnaden varit liten och konstruktionen inte orsakat någon större erosion. Kolanalysen visar ett antal små toppar. Dessa är oregelbundet förekommande och kan därför sannolikt inte knytas till borgens brand. Därför antas att branden varit begränsad. Att vattennivån i Hörnsjön sänkts under 1900- talet, beror sannolikt på de utdikningar som gjorts i utloppet för att torrlägga omkringliggande marker.

    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.

    Multi-Decadal Changes in Tundra Environments and Ecosystems: Synthesis of the International Polar Year-Back to the Future Project (IPY-BTF)2011In: Ambio, ISSN 0044-7447, E-ISSN 1654-7209, Vol. 40, no 6, p. 705-716Article in journal (Refereed)
    Abstract [en]

    Understanding the responses of tundra systems to global change has global implications. Most tundra regions lack sustained environmental monitoring and one of the only ways to document multi-decadal change is to resample historic research sites. The International Polar Year (IPY) provided a unique opportunity for such research through the Back to the Future (BTF) project (IPY project #512). This article synthesizes the results from 13 papers within this Ambio Special Issue. Abiotic changes include glacial recession in the Altai Mountains, Russia; increased snow depth and hardness, permafrost warming, and increased growing season length in sub-arctic Sweden; drying of ponds in Greenland; increased nutrient availability in Alaskan tundra ponds, and warming at most locations studied. Biotic changes ranged from relatively minor plant community change at two sites in Greenland to moderate change in the Yukon, and to dramatic increases in shrub and tree density on Herschel Island, and in sub-arctic Sweden. The population of geese tripled at one site in northeast Greenland where biomass in non-grazed plots doubled. A model parameterized using results from a BTF study forecasts substantial declines in all snowbeds and increases in shrub tundra on Niwot Ridge, Colorado over the next century. In general, results support and provide improved capacities for validating experimental manipulation, remote sensing, and modeling studies.

    Paleoenvironments, palaeoecology and palaeobiogeography of late cretaceous (campanian) faunas from the Kristianstad basin, southern Sweden, with applications for science education2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis is thematically divided into two sections: Part1 presents studies related to the palaeoenvironments,palaeoecology and palaeobiogeography of the LateCretaceous (Campanian) faunas from the KristianstadBasin of southern Sweden; Part 2 reports on applicationsof palaeontological research for science education inschools.Part 1 was based on personally conducted fieldworkand biostratigraphical analysis at various Santonian-Campanian localities throughout Skåne. However, themost complete section at Åsen provided the primary datasource and was systematically excavated with a team ofvolunteers, who employed wet-sieving methods to extractbulk fossil material from each bed within the sequence. Aseries of globally correlated temperature-induced changeswas detected in the stepwise declining abundanceand disappearance of rudists, sclerorhynchids and therajiforms Rhinobatos and Squatirhina, as well as marinecrocodilians, various mosasaurid lizard taxa. A rangeof local palaeoenvironments were also reconstructed,including estuaries, rocky coastlines, sandy beaches,drowned river valleys, shallow neritic settings, anddeeper offshore conditions. An archipelago bordering theFennoscandian landmasses also supported continentalecosystems comprising ferns, conifers and early floweringplants, with dinosaurs, pterosaurs and non-marine turtles.Trophic levels within the marine system incorporatedred algae and dinoflagellates as primary producers, withcorals, brachiopods, bivalves, echinoids, barnacles anddecapod crustaceans as benthos, and belemnites withinthe water column. Actinopterygian fish, sharks, rays andchimaeroids, chelonioid sea turtles, marine crocodilians,polycotylid and elasmosaurid plesiosaurians, variousmosasaurids and aquatic hesperornithiform birdscollectively represented middle level and apex predators.Herbivorous and carnivorous dinosaurs, lizards and softshelledtryonichid turtles evidence elements of terrestrialisland communities. The palaeobiogeographicalrelationships and dispersal of these local assemblageswas probably influenced by marine transgressions andregressions. These would have affected habitat availabilityand connectivity via changing water depths.Part 2 presents three school education projects aimed atincreasing awareness of geoscience and natural history inschools. The better integration of geological time conceptsand geosciences into the Swedish school curriculum isalso discussed. The first study described a project wherebyfossils were found in the sandboxes in preschools, andtheir use as a tool for learning about dinosaurs, fossilsand natural history. A survey of teachers and childrenfound that both increased their knowledge base throughthis approach, and that the local context of the fossilsin particular generated interest about the subject. Theconcepts of geological time was similarly addressed in thesecond study, which utilized timescale projects and otherhands-on activities to create memory triggers for childrenand students, and to demonstrate how the perspective of‘deep time’ is relevant for understanding large-scale Earthprocesses, such as evolution and environmental change.The integration of geosciences into the Swedish schoolcurriculum is currently inadequate. Therefore, the finalpaper in this sequence discusses how geosciences forman interdisciplinary bridge between school subjects andcan be used to teach geography and biology at all schoollevels.

    Mosasaur bite marks on a plesiosaur propodial from the Campanian (Late Cretaceous) of southern Sweden2010In: GFF, ISSN 1103-5897, E-ISSN 2000-0863, Vol. 132, no 2, p. 123-128Article in journal (Refereed)
    Abstract [en]

    Although plesiosaurs and mosasaurs co-existed for about 35 million years at the end of the Cretaceous, the fossil record documenting interactions between these two groups of marine reptiles is meagre. The discovery of deeply incised scars on a limb bone of an immature polycotylid plesiosaur from the latest early Campanian (in the European two-fold division of the Campanian Stage) of the Kristianstad Basin, southern Sweden, is thus significant because it represents a rare example of predation or scavenging on an immature polycotylid plesiosaur by a large mosasaur.

    First evidence of the Cretaceous decapod crustacean Protocallianassa from Sweden2016In: Geological Society, London, Special Publications, Vol. 434, p. 241-250Article in journal (Refereed)
    Abstract [en]

    An assemblage of the burrowing ghost shrimp, Protocallianassa faujasi, is described, providing the first evidence of this decapod species from Sweden. The fossils occur in successions of the informal earliest late Campanian Belemnellocamax balsvikensis zone at Åsen and the latest early Campanian B. mammillatus zone at Ivö Klack, both in the Kristianstad Basin of NE Skåne. Numerous, heavily calcified chelipeds were found within a restricted bed at Å sen that was rich in carbonate-cemented nodules. Based on the burrowing lifestyle of modern mud shrimps, we interpret these nodules as infilled burrow chambers. The low abundance of molluscs within the Protocallianassa beds is also consistent with analogous extant communities, indicating that a similar ecologically exclusive relationship ruled within the Late Cretaceous shallowmarine ecosystems.

    Implementing the Ecosystem Services Approach at the municipal level: a transdisciplinary project with coastal communities in south Sweden2014Conference paper (Other academic)
    Abstract [en]

    In Sweden a unique project supported by the Swedish Environmental Protection Agency will be developed in close collaboration with coastal municipalities in Skåne, and with a coordinating role by Skåne´s Association of Local Authorities. These municipalities face a range of different environmental challenges, from areas along the eastern coast line facing problems related to the Baltic Sea, to municipalities in the Öresund region. In this study a range of different environmental conditions and related ecosystem services, from vulnerability to floods, erosion and sea level rise to strong pressure on coastal systems from urbanization will be investigated. Research questions and directions are built on cases and scenarios which are a part of the local municipality planning process. The approach will be to study the premises of implementing the Ecosystem Services (ES) in municipal planning and decision making of five coastal municipalities. The present study will analyse past decisions, present planning and future challenges for municipality development and management from the perspective of ES, with the aim of increasing our understanding of the ES concept as a tool for sustainable development. A second aim of the project is to evaluate the potential value of connecting the ES approach to ongoing climate change adaptation in the municipalities. The project will use the six-step approach developed by the Economics of Ecosystems and Biodiversity framework (TEEB) as the main conceptual frame. This approach includes the following steps: 1) Identifying and agreeing on the problem with stakeholders, 2) Identify the ES which are most relevant and pressing in municipality planning, 3) Collect and identify the information needs and the method to collect the data, 4) Assess expected changes in ES due to decision and input from society, 5) Identify policy options based on changes in ES and 6) Assess social and environmental impacts of 1-5.

    LiDAR-datans möjligheter: en studie av senglaciala strandvallar i nordöstra Skåne och sydvästra Blekinge2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Den relativt nya tekniken LiDAR har gjort det möjligt att undersöka och kartera landformer på ett mer effektivt sätt än tidigare. Syftet med arbetet var att undersöka hur väl LiDAR-data lämpar sig för att studera de strandvallar som finns i nordöstra Skåne och sydvästra Blekinge. Metoden har mestadels bestått av GIS-arbete i ArcMap, där vi i kartbilderna illustrerat terrängen med terrängskuggning alternativt terränglutning. Det vi fick ut från GIS-metoden har vi sedan kontrollerat ute i fält. Med LiDAR har vi fått en detaljrik bild över strandvallarna. Det har visat sig att terränglutning är den bäst lämpade metoden för det syfte vi arbetat mot. Dessa kartor har sedan gått att jämföra med tidigare forskning om hur strandvallarnas förekomst ser ut. Strandvallarna kan även kopplas till de strandförskjutningskurvor som tidigare gjorts i området. Slutligen kan vi konstatera att LiDAR är en utomordentlig metod för att studera strandvallar.

    Laboratorieundersökning av filtermaterial för lakvattenbehandling - karakterisering och reningseffektivitet2007Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Lakvatten har varierande föroreningsgrad och karaktär. Det bildas då regnvatten perkolerar igenom en deponi. I en deponiverksamhet är lakvattnet den huvudsakliga påverkan på den omgivande miljön. För att begränsa föroreningshalten i naturen behöver lakvattnet samlas upp och omhändertas. Olika tekniker har utvecklats för att rena lakvatten lokalt. En teknik är att använda ett naturligt material som torv för att i första hand reducera mängden metaller och organiska föreningar. Vid Stena Metall AB:s anläggning i Halmstad sker rening av vattnet i den lokala reningsanläggningen. Reningen består av luftning och sedimentering samt ett biofilter bestående av aska och torv (SB).

    I detta examensarbete har urlakning av ett antal olika filtermaterial gjorts genom att skaka materialen i 24 h. Även en reningseffektivitetsstudie av filtermaterialet SB har gjorts. Filtermaterialet används i dag som en biobädd och fungerar som det sista reningssteget utav lakvattnet på Stena Metall AB:s anläggning i Halmstad.

    I urlakningsstudien skakades varje filtermaterial i 24 h med kranvatten. Några gränsvärden för lakvatten finns inte i dag. ”Ny föreskrift om deponering och mottagande av avfall vid deponier” träde i kraft 2005. Föreskriftens gränsvärden för icke-farligt avfall har används som jämförvärden i denna studie. Resultatet visar att det är en stor skillnad på de olika materialens urlakning. I urlakningen är det endast Bark och Metallbark som överskrider DOC-värdet.

    Reningseffektivitetsstudien utfördes genom att skaka SB med fem olika koncentrationer av koppar-, fenol- och PCB-lösningar. Fenol- och PCB-analyser ryms inte inom detta arbete utan presenteras i ett annat arbete inom projektgruppen. I studien har lakvatten och kranvatten med de fem olika koncentrationer använts parallellt och därefter jämförts mot varandra. Materialet har skakats i 24 h. Resultatet visar en god reducering av koppar i både kran och lakvatten. Det sker en reducering av ammoniumkväve i lakvattnet medan det ökar i kranvattnet.

    Kingnites diamondi gen. et sp. nov., an exceptionally large Silurian paulinitid (Annelida; Polychaeta) from shallow marine settings of Baltoscandia2012In: GFF, ISSN 1103-5897, E-ISSN 2000-0863, Vol. 134, no 3, p. 217-224Article in journal (Refereed)
    Abstract [en]

    The polychaete annelid Kingnites diamondi, a new paulinitid genus and species, is described from the Silurian of Baltoscandia. Its large maxillae differ morphologically from those of all other known paulinitids, particularly in being very elongate and having conspicuous myocoele openings and posterior portions of the first maxillae (MI). Albeit rare, this polychaete taxon is highly characteristic and appears to be confined to the Wenlock?Ludlow transitional interval on Gotland, Sweden, and ranges into the upper Ludlow on Saaremaa, Estonia. All samples yielding this species derive from strata formed in proximal carbonate platform environments. The temporal and geographical distribution indicates that it first appeared in Gotland and subsequently spread north-eastwards to the present-day Saaremaa. Kingnites diamondi adds to the list of known members of the Paulinitidae and reinforces the importance of this family, in terms of abundance and diversity, in Silurian polychaete faunas of Baltica. This is the biggest paulinitid recorded from the Silurian with an inferred body length of approximately half a metre and its diagnostic jaws may serve as a proxy for shallow water, backreef (marginal marine to lagoonal) environments.

    Naturens vandringshinder är kulturens dammar: Kulturmiljöernas betydelse vid restaurering av vattendrag med exempel från Hallstahammars kommun, Västmanlands län2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This essay is focusing on Kolbäcksåns lower part in Hallstahammar municipality, Västmanlands county in Sweden, aiming on how cultural heritage and it’s importance is treated when changes in the landscape is about to be done. Many of the historic free rivers has due to dams been divided, and the water has gone from rapid to still. If changes is about to be done to acchive approved ecological status, the risk on damaging the cultural heritage sites is palpable. Data, that’s been analyzed, has been collected through interviews with respondents from five instances in Västmanlands county. The Majority of the answers analysed reveals that a cultural heritage site is definied by the affect made by humans, that there is a historical connection and that the site is seen as a unit in the landscape. A cultural heritage site is affected whilst a natural environment site can be both affected and non-affected. When landscape changes that affects cultural heritage sites is performed, it reveals that different interests are colliding and the importance of an early collaboration between interests is performed. The thematic analyze of the answers from the interviews revealed several potential indications on conflicts and potential solutions.

    Ekens historiska utbredning och kvalitet i Lösen socken, Blekinge län: en studie utifrån ekinventeringsprotokoll från år 1819 och 18322018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Miljöer med äldre ekar hyser höga naturvärden och är viktiga för den biologiska mångfalden. Under århundraden var ekar i Sverige reglerade av kronan i syfte att kontrollera tillgången på skeppsvirke, det var således förbjudet att avverka ek på krono- och skattejord. Sedan 1800-talet har Sveriges ekbestånd fragmenterats som följd av en rad faktorer. Dessa förändringar har haft en negativ inverkan på ekberoende arter, vars livsmiljöer idag endast är spillror av vad de en gång har varit. Med syfte att ge en ökad förståelse för dagens eklandskap i samband med naturvårdens arbete har ekens historiska utbredning och kvalitet kartlagts i Lösen socken i östra Blekinge. Undersökningen grundar sig på ekinventeringsprotokoll från år 1819 och 1832, men även historiskt kartmaterial. Genom att gå ner på by- och hemmansnivå har platser med hög ektäthet under 1800-talet lokaliserats i landskapet. En studie på denna detaljnivå har aldrig tidigare utförts för Blekinge län. Resultatet visar att ektätheten för tvåhundra år sedan var högst i Lösen sockens södra och mellersta delar, närmast kusten. Dagens skyddade ekmiljöer återfinns främst i socknens sydvästra delar, vilket visar på en kontinuitet. De mellersta och sydöstra delarna omfattas däremot inte av några områdesskydd idag. En stor del av ekarna i socknen benämns i protokollen som skadade samt som ”knut- och risekar”. Böndernas åverkan på träden och socknens naturgivna förhållanden ses som möjliga faktorer till detta. Dessa ekar dög inte till skeppsvirke, men kunde å andra sidan ha utgjort viktiga livsmiljöer för vedlevande arter.

    By combining a large-scale experimental assessment on timing of insect emergence with longtermmonitoring of waterfowl hatching date, we here show that insect emergence is mainly driven bytemperature, whereas there is only a weak effect of increasing spring temperatures on inter-annualvariability in observations of waterfowl chicks. Hence, a change in timing of the mass-emergence of insectsfrom lakes and wetlands, which is the crucial food source for waterfowl chicks, will likely result in aconsumer/resource mismatch in a future climate change perspective. Specifically, we experimentally showthat a moderate increase in temperature of 38C above ambient, expected to occur within 25–75 years, leadsto a considerably (2 weeks) earlier, and more pronounced, peak in insect emergence (Chironomus sp).Moreover, by utilizing long-term Citizen Science databases, ranging over several decades, we also showthat common waterfowl species are unable to significantly adjust their reproduction to fit futuretemperature increase. Hence, based on our data we predict a future mismatch between insect emergenceand waterfowl species basing their reproduction on temperature. This will have a profound impact onreproductive success and population dynamics of many aquatic birds, as well as on freshwaterbiodiversity.

    The effects of vegetation on the hydraulic residence time of stormwater ponds2014In: Proceedings of the 19th IAHR-APD Congress 2014, Hanoi, Vietnam, 2014Conference paper (Refereed)
    Abstract [en]

    Storm water ponds treat polluted run-off from urban areas, highways and agricultural land. Vegetation plays a key role in water treatment, but further understanding is required to identify how vegetation density and spatial distribution within a pond affect the residence time, an important parameter with respect to water treatment. This paper presents results from a preliminary study where the residence time distribution and discharge of a water treatment pond were measured at two stages within the vegetation’s seasonal growth cycle, representing the minimum and maximum states of the vegetation’s density. The results show clear and significant differences between the residence time distribution for the two cases, and highlight the need for further work on the topic.

    Changes Versus Homeostasis in Alpine and Sub-Alpine Vegetation Over Three Decades in the Sub-Arctic2012In: Ambio, ISSN 0044-7447, E-ISSN 1654-7209, Vol. 41, p. 187-196Article in journal (Refereed)
    Abstract [en]

    Plant species distributions are expected to shift and diversity is expected to decline as a result of global climate change, particularly in the Arctic where climate warming is amplified. We have recorded the changes in richness and abundance of vascular plants at Abisko, sub-Arctic Sweden, by re-sampling five studies consisting of seven datasets; one in the mountain birch forest and six at open sites. The oldest study was initiated in 1977–1979 and the latest in 1992. Total species number increased at all sites except for the birch forest site where richness decreased. We found no general pattern in how composition of vascular plants has changed over time. Three species, Calamagrostis lapponica, Carex vaginata and Salix reticulata, showed an overall increase in cover/frequency, while two Equisetum taxa decreased. Instead, we showed that the magnitude and direction of changes in species richness and composition differ among sites.

    Praktiska moment - En god vana inom geografiundervisningen?: en intervjustudie av gymnasielärares uppfattningar kring ett praktiskt arbetssätt2013Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Geografi är ett tvärvetenskapligt ämne i skolans värld som berör såväl naturen som samhället vi lever i. I Skolverkets ämnesplan för ämnet Geografi på gymnasial nivå framkommer det med all önskvärd tydlighet att såväl exkursioner, fältstudier, laborationer som övningar ska ingå i undervisningen, för att åskådliggöra den mångfacetterade värld vi lever i. I nya rön från Skolverket beskrivs situationen i de högre åldrarna, med avseende på inkludering av praktiska moment i undervisningen, som problematisk.

    Det övergripande syftet med denna uppsats är att belysa vikten av praktiska moment inom ämnet geografi, på gymnasial nivå, genom att undersöka lärares erfarenheter kring ett praktiskt arbetssätt. För att kunna undersöka detta har vi använt oss av en intervjustudie, där fyra geografilärare (på gymnasial nivå) från fyra olika skolor i tre skilda kommuner agerade respondenter. Resultatet påvisar att eleverna till följd av ett kontinuerligt tillämpande av praktiska moment ges möjligheten att se samband, vilka knyter samman teorin och verkligheten. Utöver detta kan även vissa positiva synergieffekter påvisas, däribland återfinns den sociala faktorn och en förändrad syn på ämnet. Genomgående har vi kunnat skönja att en nyckelterm, för såväl lärare som elever, inom ett praktiskt arbetssätt, är vana.

    GIS - Geografilärarnas akilleshäl?: en intervjustudie av gymnasielärares arbetssätt kring Geografiskt informationssystem2013Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I den nya ämnesplanen för ämnet geografi har momentet GIS fått en allt tydligare plats med centrala mål som skall uppnås i undervisningen. Målen visar på att ett praktiskt arbetssätt, gärna med digitala läromedel, erfordras för att uppnå målen på bästa sätt. Hur ser detta faktum ut i dagens skolor egentligen?

    Syftet med denna uppsats är att undersöka hur lärare på gymnasieskolor bedriver undervisning i momentet GIS. För att få svar på denna fråga genomfördes intervjuer med sex lärare på tre olika skolor som på olika sätt bedriver undervisning i GIS. Resultatet visar på att det finns en rådande kunskapsbrist bland lärare, där stöd i form av utbildning och skolanpassat material rörande GIS är en stor önskan bland lärarna. Generellt är lärarna positivt inställda till GIS och ser möjligheter, men även hinder i form av tid, kunskap och kostnader.

    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.

    Effect of microalgal treatments on pesticides in water2016In: Environmental Technology, Vol. 37, no 7, p. 893-898Article in journal (Refereed)
    Abstract [en]

    The effect of the microalgae Chlorella vulgaris on a wide range of different pesticides in water was studied. Treatments included short-term exposure (1 h) to living and dead microalgal biomass and long-term exposure (4 days) to actively growing microalgae. The initial pesticide concentration was 63.5 ± 3.9 µg L−1. There was no significant overall reduction of pesticides after short-term exposure. A significant reduction of the total amount of pesticides was achieved after the long-term exposure to growing microalgae (final concentration 29.7 ± 1.0 µg L−1) compared with the long-term control (37.0 ± 1.2 µg L−1). The concentrations of 10 pesticides out of 38 tested were significantly lowered in the long-term algal treatment. A high impact of abiotic factors such as sunlight and aeration for pesticide reduction was observed when the initial control (63.5 ± 3.9 µg L−1) and the long-term control (37.0 ± 1.2 µg L−1) were compared. The results suggest that water treatment using microalgae, natural inhabitants of polluted surface waters, could be further explored not only for removal of inorganic nutrients but also for removal of organic pollutants in water.

    Landsbygdens återkomst - mångsysslare i ny produktion: Löderup och Valleberga socknar om 10 till 15 år2005Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    The essay on ”The revival of the countryside – a multitalent in landproduction.” focuses on local and regional development within agriculture, foodprocessing and tourism.

    Due to great changes in society, the inhabitants in rural areas are forced to find alternative occupations. Using history as a tool to build up the future is a main factor in rural development. Apart from this it involves cooperation, resources, cultural heritage and values, entrepreneurship and innovation, economic vitality, and an understanding of markets and marketing. They all contribute to a region`s ability to benefit from rural development.

    Utanverken - en oas mitt i staden: en enkätundersökning om upplevelsekaraktärer, kulturella ekosystemtjänster och utveckling i Utanverken, Kristianstad2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I dagsläget finns ett stort behov av exploatering för nya bostäder och förtätning i många svenska städer. Bra boende - och livsmiljöer innefattar ofta en närhet till grönområden. Utanverken i Kristianstad, Skåne län, är ett grönområde med höga natur - och kulturvärden. Omkring området planeras en stor exploatering av bostäder vilket betyder att grönområdet är viktigt för staden. Genom grönområden kan olika upplevelsekaraktärer upplevas och olika kulturella ekosystemtjänster tas ut. Dessa karaktärer och tjänster är en viktig hälsoaspekt för människan. För att ta reda på vilka upplevelsekaraktärer och kulturella ekosystemtjänster som upplevs och utnyttjas av de boende omkring undersökningsområdet idag genomfördes en enkätundersökning. Resultatet visar att det finns karaktärer och tjänster som upplevs och utnyttjas mer än andra. Däremot finns det meningsskiljaktigheter kring utveckling av undersökningsområdet mellan olika grupper av de boende. För att tillgodose dagens och framtidens invånares önskningar bör det alltid föras en dialog mellan beslutsfattare och invånare. Vid planering av grönområden bör det även tas i beaktande över vilka funktioner dessa bör innehålla för att främja speciella upplevelsekaraktärer och kulturella ekosystemtjänster för skapandet av bra boendemiljöer i urbana områden.
