1. 16. Day or night? Testing thermal imaging technology for estimating ungulate population densities in southern Sweden

   Master-uppsats, SLU/Southern Swedish Forest Research Centre

   Författare :Julia Nowak; [2023]
   Nyckelord :monitoring; ungulates; thermal imaging; population density; distance sampling; Dama dama;

   Sammanfattning : To be able to make a proper judgement and choose the best management or conservation solution when working with populations of wild ungulates or any other wildlife, it is important to obtain good estimates of population densities. Inventing or improving wild animal monitoring methods is a key to protect what may be endangered or to avoid human-wildlife conflicts. LÄS MER

3. 17. Hunden som resurs inom svensk naturvård

   Kandidat-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

   Författare :Tina Jensen; Sofie Langanger; [2023]
   Nyckelord :nature conservation; environmental conservation; conservation detection dog; scat detection dog; endangered species; invasive species; naturvård; miljövård; naturvårdssökhund; spillningsinventering; hotade arter; invasiva arter;

   Sammanfattning : Användningen av sökhundar som hjälpmedel och verktyg inom naturvården är i Sverige hittills ett litet område med några få verksamma aktörer. Men precis som hos tull, polis och försvarsmakt kan hundarna implementeras i naturvårdsverksamheten som ett standardverktyg. LÄS MER

4. 18. Quantity and quality of oaks (Quercus) as suitable habitats for the longhorn beetle species Plagionotus detritus : An inventory study in Stockholm and Uppsala County, Sweden

   Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

   Författare :Ida Widegren; [2023]
   Nyckelord :Plagionotus detritus; P. detritus; Cerambycidae; Cerambycinae; longhorn beetle; insects; habitat; oak; Quercus; conservation; ecology; endangered; threatened;

   Sammanfattning : The longhorn beetle Plagionotus detritus is associated with newly dead oak wood and is declining throughout its distribution range. In Sweden, P.detritus has displayed one of the most dramatic reductions in distribution recorded for insect species and is near regional extinction. LÄS MER

5. 19. Stimbeteende hos glochidieinfekterade och icke-infekterade elritsor

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

   Författare :Madeleine Blomqvist; [2023]

   Sammanfattning : The thick shelled river mussel belongs to a highly endangered group of organisms worldwide. A parasitic larval stage is included in the mussel's life cycle where its glochidia larvae attach to the gills of a host fish. LÄS MER

7. 20. 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
