  2. 1. Magnetic map sense in animals: effects of geographic and magnetic displacements

    Author : Jannika Boström; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Oenanthe oenanthe; skylight polarization; geomagnetic map; geomagnetic field; endogenous migration programme; migratory fuelling; orientation; animal navigation;

    Abstract : Migration research is a large and diverse field and in my thesis I have focused on the impact of geomagnetic cues on animal orientation, navigation and migratory fuelling. Several animal species from widely different taxa possess the ability to sense and make use of geomagnetic information during migratory or homing events. READ MORE

  6. 4. Getting informed in a risky world : risk assessment, predator information & parental decisions

    Author : Nicole Schneider; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Predation ultimately affects the fitness of individuals. In nest building species like birds, the predation of dependent offspring is the most important source of reproductive failure, favouring the selection of parental adaptations to enhance offspring survival. READ MORE

  7. 5. When climate is changing: effects of phenology and local climate on individual fitness

    Author : Meit Öberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The fitness impacts of climate change on seasonal breeding organisms is, in part, linked to local climatic effects on phenology (i.e. the timing of major life events, such as breeding and migration) and how these relate to temporal changes in resource distribution. READ MORE
