  1. 11. Klimateffektsrelaterade förändringar i fenologi och morfologi hos en population av huggorm (Vipera berus)

    University essay from SLU/Dept. of Ecology

    Author : Patric Falck; [2022]
    Keywords : fenologi; huggorm; klimatförändringar; melanism; morfologi; storleksförändring; Vipera berus; våraktivitet; ömsning;

    Abstract : Förändringarna i klimatet har ofta negativa konsekvenser på hela ekosystem där enskilda djurarter och deras habitat drabbas, där reptiler och amfibier inte är något undantag. Analys av huggormsdata från insamlat material sedan början av 1940 – talet till slutet av 1990 - talet avslöjar hur huggormar tros påverkas av ett förändrat klimat. READ MORE

  3. 12. Examining the Link between Temperature and Flight Phenology in Hoverflies (Diptera: Syrphidae) Using Swedish Citizen Science Data

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Malin Magnusson Rundqvist; [2021]
    Keywords : climate change; hoverfly; phenology; pollinator; Sweden; Syrphidae;

    Abstract : Global warming is causing a general trend of rising temperatures worldwide. Simultaneously there is also a decline in populations of pollinators all over the world. Therefore, it is important to examine the effect warming temperatures might have on different pollinator species. READ MORE

  4. 13. Evolution of flowering time in a changing environment

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Emmy Sköld; [2021]
    Keywords : flowering time; evolution; Arabidopsis thaliana; environmental effects; adaptations; flowering phenology;

    Abstract : How come the same species of plants can naturally occur under various conditions in different parts of the world? A plant's ability to adapt in response to a changing climate hinges on the presence of genetic variation in traits, such as flowering phenology. In this study, I examine whether flowering start varies genetically within populations and compare this variation to differences between populations. READ MORE

  5. 14. Relating land-use and plant biodiversity in Scanian semi-natural grazing lands

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Timothy Micallef; [2021]
    Keywords : Physical Geography; Ecosystem Analysis; Land-use; Biodiversity; Grazing land; Remote sensing; Earth and Environmental Sciences;

    Abstract : Climate change and biodiversity loss are amongst the most pressing environmental issues internationally, with far-reaching impacts that place natural and semi-natural habitats at ever greater risk of degradation. My project explores the effects of land-use on plant biodiversity in semi-natural grazing lands using datasets covering Sweden’s southernmost region, Scania. READ MORE

  6. 15. Spatiotemporal variation in the relative fitness of a northern and a southern ecotype of Arabidopsis thaliana

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Jonathan Gyllingberg; [2021]
    Keywords : Arabidopsis thaliana; fitness; evolution; ecotype; genotype; flowering phenology; fecundity; local adaptation;

    Abstract : Terrestrial plants exist in almost every habitat on the earth, ranging from warm and moist tropical rainforests, hot and dry deserts, and to cold and barren tundras. Furthermore, a single species may encounter different climatic conditionshabitats within its range distribution which climatic conditions differs from one to another. READ MORE
