  3. 2. The use of regurgitated pellets from the great cormorant to detect the presence of the round goby

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Tim Dorup; [2023-08-07]
    Nyckelord :Invasive species; Regurgitated pellets; Great cormorant; Round goby; dPCR;

    Sammanfattning : The round goby (Neogobius melanostomus) is an invasive alien species that poses one of the greatest threats to biodiversity and ecosystem services in Sweden today. The round goby originates from the Black Sea and Caspian Sea but has in recent decades rapidly spread with global shipping traffic to new areas in Europe and North America. LÄS MER

  4. 3. Estimating historic ranges of extinct scavenging birds from North America during the late Pleistocene using co-occurrence data from the fossil record

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Melissa Miranda; [2023-06-30]
    Nyckelord :Scavenging birds; Vultures; Co-occurrence Data; Range Estimates; Spatial Autoregressive Models; Co-extinction;

    Sammanfattning : The aim of my study was to estimate and compare the historic range of nine scavenging birds from North America that went jointly extinct with their mammalian megafaunal prey in the Late Pleistocene. Although the severity and timing of their co-extinction are strongly correlated, there has been little analytical support in providing estimates for the possible geographic distribution of scavenging birds prior to the extinction event.

  7. 5. Evaluation of the ERA5-Land dataset for estimation of soil moisture in the permafrost region

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Alberta van Gent; [2023]
    Nyckelord :Soil moisture; ERA5-Land; International Soil Moisture Network ISMN ; permafrost region;

    Sammanfattning : The permafrost region covers a vast area of land surface on the northern hemisphere,storing large amounts of carbon. Unfortunately, climate warming leads to permafrostthaw altering the hydrothermal state of permafrost soils. Due to the remoteness of thepermafrost region, access to field measurements is restricted.
