  1. 1. Detectability of insects in Malaise traps : assessing insect detectability in Malaise traps through High-Resolution Sampling, and development of a novel marking technique

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Viktor Gårdman; [2023]
    Nyckelord :Malaise trap; activity; movement; weather; mark-recapture; detectability; insects;

    Sammanfattning : Malaise traps are extensively used in insect surveys and studies, yet the detectability of insects in relation to the traps remain unknown. Detectability is the odds that a taxon ends up in a trap, given that the taxon is present in the area around the trap. LÄS MER

  3. 2. Status of three great crested newt Triturus cristatus populations after translocation

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Filippa Hedenberg; [2022]
    Nyckelord :amphibians; Caudata; capture-mark-recapture; breeding population size; body condition; conservation;

    Sammanfattning : The great crested newt Triturus cristatus has a high legal protection in Europe through the Bern Convention and Habitats Directive, which often come into conflict with human development. Translocation of populations are increasingly being used as a “solution” to this conflict, but the implications for the populations’ status are not known. LÄS MER

  4. 3. Long-term population dynamics in a population of grass snakes (Natrix natrix) : and implications of climate change

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Ludvig Palmheden; [2022]
    Nyckelord :body condition; hibernaculum; long-term data; mark-recapture; population size;

    Sammanfattning : The impact of climate change on reptile populations is poorly studied, and this includes snakes, which are elusive by nature, making it problematic to preform long-term population studies. Here we have done both. LÄS MER

  5. 4. Creating an Application for Crowdsourcing the Data Collection of Northern Pike

    Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Filip Hultgren; Christopher Rydell; Max Rylander; [2019]
    Nyckelord :;

    Sammanfattning : Northern pike (Esox Lucius) serves an important role in the ecosystem of the Baltic sea, and is therefore commonly used as a model species for studying the entire ecosystem. Photographic mark-recapture is a method for studying animal populations through the tracking of individual animals based on photographs of distinctive markings on their bodies. LÄS MER

  7. 5. Wildlife corridor use amongst reticulated giraffes (Giraffa camelopardalis reticulata) at Ol Pejeta Conservancy, Kenya

    Master-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Johanna Lund; [2019]
    Nyckelord :Giraffa camelopadalis reticulata; reticulated giraffe; migration; photographic mark-recapture; Ol Pejeta Conservancy; Laikipia; Kenya; wildlife corridor;

    Sammanfattning : The African continent is home to many large and unique wildlife species and is, as is commonly known, considered to be the birthplace of the human race. The numbers and strength of this wide array of species is however diminishing rapidly before our eyes (Campbell et al., 2003; Ogutu et al., 2016). LÄS MER
