  1. 1. Diving Deep: Seabird foraging tactics and local prey field

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Elin Andersson Sjöholm; [2024]
    Keywords : Common Guillemot; Uria aalge; Optimal Foraging theory; Hydroacoustic data; resource selection;

    Abstract : Foragers in patchy environments need to decide what patches to use and how to allocate their time between them. Optimal foraging theory describes these choices through the relationship between energy expenditure and energy gain. READ MORE

  3. 2. Werewolves to Are-wolves? Characterising key factors affecting public acceptance of a hypothetical Experimental Wolf Reintroduction in Scotland

    University essay from Lunds universitet/Internationella miljöinstitutet

    Abstract : The newest Scottish government Biodiversity Strategy prioritises control of overabundant deer populations. Ecological theory and real-life instances suggest an unorthodox deer management solution: wolf reintroduction (WR). Theoretically, wolves would prey on deer, thus alleviate grazing pressure on Scottish vegetation and help landscapes thrive. READ MORE

    Author : Pieter Otte; [2022]
    Keywords : climate change; snow cover; seasonal colour coat; crypsis; mismatch; camera trap; survival analysis;

Several mammalian and avian species in the northern hemisphere express a seasonal colour coat (SCC) making them white in winter periods and brown or dark in summer. READ MORE

  6. 5. The evolutionary origins of phagocytosis in microbial populations
