  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

    University essay from SLU/Dept. of Ecology

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

    Abstract : 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. READ MORE

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

    Keywords : amphibians; Caudata; capture-mark-recapture; breeding population size; body condition; conservation;

    Abstract : 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. READ MORE

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

    Abstract : 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. READ MORE

    Keywords : ;

    Abstract : 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. READ MORE

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