    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 LIFE GoodStream project in Trönninge:current and expected effects on amphibianpopulations and otter presence : in collaboration with LIFE GoodStream andHushållningssällskapet in Halland

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap; Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Författare :Sofia Hedman; Karin Jermer; [2019]
    Nyckelord :;

    Sammanfattning : LIFE GoodStream is an EU-financed conservation project, which strives to improve the ecologicalstatus of a stream in the agricultural landscape of Halland County, Sweden. Since 2015, the project hasconstructed amphibian ponds, restored wetlands, removed dispersal barriers and worked to return theTrönninge stream (Trönningeån) to more natural conditions. LÄS MER

  3. 3. 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

  4. 4. 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

  5. 5. 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
