    Nyckelord :värdväxter; insekter; nattfjärilar; säckmalar; Lepidoptera; Coleophora; lövminerare; småfjärilar; fjärilslarver; rödlistade arter; hotade arter; pollinerare;

    Sammanfattning : Att stoppa utarmning av biologisk mångfald och livsmiljöer är en stor utmaning och en ödesfråga för mänskligheten. Klimatförändringar, exploatering, kalhyggesskogsbruk, intensivt brukad jordbruksmark, invasiva arter och miljögifter medför att jorden är inne i sitt sjätte utdöende. LÄS MER

  3. 2. The effects of fishing on stability of a food web under climate warming

    Master-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Gabriel Nordström; [2023]
    Nyckelord :fishing; climate change; temperature; predator; consumer; resource; stage-specific; food webs; ontogenetic assymetry; biomass overcompensation; emergent Allee effects; limit cycles;

    Sammanfattning : Predicting the effects of fishing in a warmer environment caused by climate change requires knowledge of what trophic level is fished on, the physiological effects of temperature on fish, and how these two affect ecological interactions. Both temperature and fishing are known to affect the stability of food webs in several ways. LÄS MER

  4. 3. Effects of clear-cut logging on five old-growth forest bryophyte species. : How does the most common forestry method in Sweden impact vulnerable forest specialists?

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Nathalie Edwards; [2023]
    Nyckelord :Bryophytes; old-growth forests; forestry; nature conservation; sustainable forestry; mossor; gammelskog; skogsbruk; naturvård; hållbart skogsbruk;

    Sammanfattning : Clear-cut logging is the most widely practised forestry method in Sweden. This often conflicts with nature conservation and leads to issues where economic interests are pitted against ecological values. LÄS MER

  5. 4. Detecting structural variants in the DNA of the inbred Scandinavian wolf

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Lars Huson; [2023]
    Nyckelord :animal; animal population; bioinformatics; biological sciences; biology; Canis lupus; CNV; conservation genetics; conservation genomics; copy-number variation; DNA; endangered population; endangered species; evolution; evolutionary biology; extinction; genetic diversity; genetics; genetic variation; genomes; genomics; grey wolf; inbreeding; inbreeding depression; indel; mutation; pedigree; population genetics; population genomics; Scandinavia; smoove; snakemake; structural variant; SV; wolf; wolves;

    Sammanfattning : Only 40 years ago, just three individuals made the journey from Finland/Russia to found the current wolf population in the southwest of Sweden. This population, that to this date descends from less than 10 founders, has a substantial increased extinction risk due to inbreeding. LÄS MER

  7. 5. Utmarken - envisioning Skåne's new edible landscapes

    Master-uppsats, Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Hugo Settergren; [2022]
    Nyckelord :Food Urbanism; Agroforestry; Urban Planning; Permaculture; Edible landscapes; Urban Agriculture; Resillience; Arts and Architecture;

    Sammanfattning : Planet earth is getting hotter and regional climates are becoming increasingly unpredictable across the globe. Cities and communities on all continents are already impacted by the changing climate, but also by two other crises – the fossil-energy decent and the 6th mass extinction event. LÄS MER
