  1. 1. Neophobia and parental care in collared flycatchers (Ficedula albicollis)

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Maja Svedberg; [2023]
    Keywords : Neophobia; collared flycatcher; ficedula albicollis; parental care;

  3. 2. Not everything that glitters is gold : does linear infrastructure create an ecological trap for golden eagles?

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Michelle Etienne; [2020]
    Keywords : HIREC; animal ecology; animal movement; animal behaviour; integrated step selection function; wildlife traffic accidents; maladaptive behaviour; fitness; habitat selection;

    Abstract : Animals can be caught in an “ecological trap” when they select for seemingly attractive habitats at the expense of their fitness. This maladaptive behaviour is often a consequence of human induced rapid changes in their natal environment, such as the development of linear infrastructure, where roads and railways create novel feeding conditions through traffic induced mortality of other species and powerline areas provide perching or nesting sites.

    University essay from SLU/Dept. of Animal Environment and Health

    Author : Maja Wedin; [2016]
    Keywords : broiler chicken; perching; sleeping behaviour; welfare; hybrids; organic production;
