  1. 1. Analyzing Factors Influencing Reproductive Success of the Mountain Chicken : Nordens Ark Captive Breeding Program

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Chad Donaldson; [2019]
    Nyckelord :frog; frogs; mountain chicken; mountain chicken frog; leptodactylus; fallax; herpetology; amphibian; amphibians; multiple linear regression; statistical analysis; Nordens Ark; captive breeding; zoo; zoology; conservation; endangered species; grodor; groda; kycklinggroda; Nordens Ark; amfibier; zoologi; herpetologi; analys; hotade arter; bevarande; avel;

    Sammanfattning : Amphibians globally are declining with roughly a third facing extinction due primarily to threats linked to human impacts. One way in which this is being combated is by captive breeding programs. LÄS MER

  2. 2. The use of environmental DNA (eDNA) in biological monitoring of the Natterjack toad (Epidalea calamita)

    Master-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Lærke Breum Blom; [2018]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Environmental DNA (eDNA) is a promising new tool in the field of conservation management, which can contribute to non-destructive species determination as well as improved data on species occurrence. Still, it is important to gain knowledge on how eDNA works compared to conventional monitoring methods in order to evaluate the detection efficiency. LÄS MER

  3. 3. Importance of sampling design using an eDNA monitoring approach for pond-living amphibians

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Sabrina Mittl; [2017]
    Nyckelord :eDNA; amphibians; non-invasive sampling; genetic monitoring;

    Sammanfattning : The eDNA approach for monitoring aquatic species is already widely used. However, there are still uncertainties, for instance regarding the distribution of target DNA in ponds. These uncertainties need to be addressed when using eDNA in management. LÄS MER

  4. 4. Stigande havsnivåers påverkan på hotade groddjur

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Linn Andersson; [2017]
    Nyckelord :havsnivåhöjning; klimatförändringar; kustnära habitat; groddjur; bevarandearbete; naturvård; GIS; Earth and Environmental Sciences;

    Sammanfattning : Climate change and biodiversity loss are two of the major challenges of our time, and are strongly interconnected. Sea level rise is a consequence of these and a significant threat to global coastal habitats. LÄS MER

  5. 5. Semi-natural pastures in Scania: grazing and the support system

    Kandidat-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Dan Gerell; [2016]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Semi-natural pastures are one of the most species-rich habitats found in Sweden and many endangered species are connected to them. Strongly declining in area, semi-natural pastures in Sweden can be eligible for financial support within the EU agri-environmental scheme. LÄS MER
