    Translocation of an arctic seashore plant reveals signs of maladaptation to altered climatic conditions2020In: PeerJ, E-ISSN 2167-8359, Vol. 8, article id e10357Article in journal (Refereed)
    Abstract [en]

    Ongoing anthropogenic climate change alters the local climatic conditions to which species may be adapted. Information on species’ climatic requirements and their intraspecific variation is necessary for predicting the effects of climate change on biodiversity. We used a climatic gradient to test whether populations of two allopatric varieties of an arctic seashore herb (Primula nutans ssp. finmarchica) show adaptation to their local climates and how a future warmer climate may affect them. Our experimental set-up combined a reciprocal translocation within the distribution range of the species with an experiment testing the performance of the sampled populations in warmer climatic conditions south of their range. We monitored survival, size, and flowering over four growing seasons as measures of performance and, thus, proxies of fitness. We found that both varieties performed better in experimental gardens towards the north. Interestingly, highest up in the north, the southern variety outperformed the northern one. Supported by weather data, this suggests that the climatic optima of both varieties have moved at least partly outside their current range. Further warming would make the current environments of both varieties even less suitable. We conclude that Primula nutans ssp. finmarchica is already suffering from adaptational lag due to climate change, and that further warming may increase this maladaptation, especially for the northern variety. The study also highlights that it is not sufficient to run only reciprocal translocation experiments. Climate change is already shifting the optimum conditions for many species and adaptation needs also to be tested outside the current range of the focal taxon in order to include both historic conditions and future conditions. ©2020 Hällfors et al.

    Kvinnorna och klimatet i AI-revolutionen: En kvalitativ intervjustudie med personer inom AI-sektorn i Sverige, om vilka föreställningar om AI som finns i relation till genus och klimat2023Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Sedan dess tidiga start på 60-talet växer idag Artificiell Intelligens (AI) i revolutionerande fart och används idag i områden från sjukvård, digitala klockor, domstolar, offentliga toaletter, preventivmedel eller till energisystem. Den breda implementeringen och data växer storslaget fram på marknaden. Men AI-tekniken bidrar även till att bland annat kvinnor drabbas av stereotypa könsroller som programmeras in, trots att kvinnor är de som 1) använder tekniken minst och 2) är underrepresenterade inom tech-sektorn. Ur ett etiskt perspektiv finns även andra problematiska svårigheter med AI i förhållande till dess utsläpp och påverkan på klimatet. Syfte: Syftet med arbetet är att studera vilka föreställningar om AI personer som är verksamma inom sektorn i Sverige har, med särskild hänsyn till genus och klimat. Frågeställning: Vilka föreställningar har personer verksamma inom AI-sektorn i relation till genus och klimat? Metod och teori: En kvalitativ metod har använts där halvstrukturerade intervjuer har gjorts med fyra personer. En kvalitativ innehållsanalys har gjorts vid analyserandet av intervjutranskriberingarna. I Analysen tillämpas Yvonne Hirdmans genusteori. Slutsats: AI diskursen med dess mestadels positiva konnotationer har ett stadigt grepp inom sektorn. Inget av de aktuella projekten som informanterna är verksamma i nu tillämpar något specifikt etiskt regelverk, bortsett från de etiska riktlinjer som varje enskild organisation som är involverad i projektet har. Det finns en viss medvetenhet om etikrelaterade problem med AI kopplat till genus och klimatförändringar, men inget större engagemang i att hantera det eller att granska egna utsläpp. Huvudfokus är hur AI kan tillämpas för att hantera olika samhällsutmaningar.

    Återbruk av trämaterial i byggnader för en cirkulär ekonomi2023Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Ett hållbart byggande är ett koncept som kan användas i en cirkulär ekonomi, som inriktar sig mot att begränsa kostnader av råvaror med bibehållen kvalitet och att ta vara på resurser som senare kan återanvändas i cirkulära processer. Underskottet av bostäder i Sverige är fortfarande högt och man ser ett behov av en fortsatt tillväxt på bostadsmarknaden de kommande åren. För att möta globala klimatrelaterade, ekonomiska och sociala utmaningar behöver byggnationer anpassas till att vara mer resurseffektiva och miljövänliga. Återbruk av byggmaterial i trä och renoveringar av befintliga byggnader är inget nytt begrepp men det finns potential att utnyttja det effektivare i framtiden. Om utvecklingen med återbruk drivs vidare kan man närma sig cirkulära processer inom byggsektorn, vilket är ett viktigt steg mot ett klimatneutralt samhälle. Det ställs hårdare krav på att tillvarata värden och ökade kunskaper i hanteringen för återanvändning av trämaterial från äldre byggnader. Men det behövs mer studier hur upprustning och renovering av redan befintliga äldre byggnader kan ses som ett miljövänligt och samtidigt ekonomiskt alternativ i jämförelse med nyproduktion.

    Är Sveriges områdesskydd klimatanpassat?: En geografisk analys över hur mycket av Sveriges skyddade natur som påverkas vid en havsnivåhöjning.2020Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Due to climate change and global warming, there is an ongoing sea level rise. IPCC has published four climate scenarios that show the projected changes in climate until the year 2100. The global sea levels are estimated to rise between 28 and 98 cm, which will result in great consequences for coastal landscape and protected nature. This study is the first in Sweden to analyze which consequences a sea level rise will have on protected nature in Sweden. A geographical analysis has been made of how much of the Swedish nature reserves and Natura 2000-habitat types that are going to be covered by the sea in three of the climate scenarios. The sea will cover more than 5% of the total area in 34-102 nature reserves depending on which scenario takes place, which means a loss of 750-4640 hectares. More than 5% of 14-15 Natura 2000-habitat types in Sweden will be covered by the sea. Four of the habitat types that are most affected in the worst scenario are; Annual vegetation of drift lines (46%), Salicornia and other annuals colonizing mud and sand (85%), Atlantic salt meadows (42%) and Boreal Baltic coastal meadows (44%). Recent research has shown that habitat loss due to climate change and sea level rise can be avoided if species and habitats are allowed to move inland, and that management of surrounding areas are of high importance in conservation biology. It is therefore essential to use conservation strategies that are adapted to sea level rise.

    Possibilities of rewetting agricultural land for decreasing greenhouse gas emission and sustainable adaptation to flooding: -A case study from two sites in Sweden2015Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The consequence of climate change will be more flooding in some areas and problems with sea-level rise. Drained wetlands and lakes that today are used for agriculture in the future may need to be rewetted because it might be unsustainable to continue to drain them. Rewetting these lands will have many positive effects like for instance decreased greenhouse gas emissions since these lands due to their high organic matter content are emitting a lot of CO2 and N2O.

    In this study two sites that could become candidates for rewetting have been studied and compared for their CO2 and N2O emissions. This was done by using a method for sampling gases both from a closed chamber and directly from soil. The emission rates were higher for Ramsjön compared to Vesan for both gases that could probably be an effect of season. A strong covariation between the two gases was shown for Ramsjön and the relationship was fairly strong for Vesan this indicates a common process for releasing the two gases. Rewetting these areas would probably have a high potential for saving greenhouse gas emissions and possibly also serve as flood adaptation areas with a high biodiversity and recreational value.

    The greenhouse gas emission effects of rewetting drained peatlands and growing wetland plants for biogas fuel production2021In: Journal of Environmental Management, ISSN 0301-4797, E-ISSN 1095-8630, Vol. 277, article id 111391Article in journal (Refereed)
    Abstract [en]

    Efforts to mitigate greenhouse gas (GHG) emissions are receiving increased attention among governmental and commercial actors. In recent years, the interest in paludiculture, i.e. the use of rewetted peatlands, has grown because of its potential to reduce GHG emissions by stopping soil decomposition. Moreover, cultivating wetland plants on rewetted peatlands for  bioenergy production that replaces fossil fuels in the transport sector, can contribute to additional GHG emission reductions. In this study, an analysis of literature data was conducted to obtain data on GHG emissions (CO2 and CH4) and biomass production from rewetted peatlands cultivated with two different wetland plant species: Phragmites australis (Pa) and Typha latifolia (Tl). In  addition, a  biogas experiment was carried out to investigate the biomethane yield of Pa and Tl biomass, and the reduction of global warming potential (GWP) by using biomethane as vehicle fuel. The results show that peatland rewetting can be an important measure to mitigate the GWP as it reduces GHG emissions from the soil, particularly on a 100-year timescale but also to some extent on a 20-year timescale. More specifically, rewetting of 1 km2 of peatland can result in  a  GWP reduction corresponding to  the  emissions from ±2600 average sized petrol cars annually. Growing Pa on rewetted peatlands reduces soil GHG emissions more than growing Tl, but Pa and Tl produced similar amounts of biomass and biomethane per land area. Our study concludes that Pa, because of a more pronounced GWP reduction, is the most suitable wetland plant to cultivate after peatland rewetting. © 2020 The Author(s). Published by Elsevier Ltd.

    Thermal adaptation affects interactions between a range-expanding and a native odonate species2013In: Freshwater Biology, ISSN 0046-5070, E-ISSN 1365-2427, Vol. 58, no 4, p. 705-714Article in journal (Refereed)
    Abstract [en]

    1.Increasing temperature and invading species may interact in their effects on communities. In this study, we investigated how rising temperatures alter larval interactions between a naturally range-expanding dragonfly, Crocothemis erythraea, and a native northern European species, Leucorrhinia dubia. Initial studies revealed that C.erythraea grow up to 3.5 times faster than L.dubia at temperatures above 16 degrees C. As a result, we hypothesised that divergent temperature responses would lead to rapid size differences between coexisting larvae and, consequently, to asymmetric intraguild predation at higher ambient temperatures. 2. Mortality and growth rates were measured in interaction treatments (with both species present) and non-interaction controls (one species present) at four different temperature regimes: at an ambient temperature representative of central Germany, where both species overlap in distribution, and at temperatures increased by 2, 4 and 6 degrees C. 3.The mortality of C.erythraea did not differ between treatment and control. In contrast, mortality of L.dubia remained similar over all temperatures in the controls, but increased with temperature in the presence of the other species and was significantly higher there than in the controls. We concluded that L.dubia suffered asymmetric intraguild predation, particularly at increased temperature. Reduced growth rate of L.dubia in the interaction treatment at higher temperatures also suggested asymmetric competition for prey in the first phase of the experiment. 4.The results imply that the range expansion of C.erythraea may cause reduction in population size of syntopic L.dubia when temperature rises by more than 2 degrees C. The consequences for future range patterns, as well as other factors that may influence the interaction in nature, are discussed. © 2013 Blackwell Publishing Ltd.
