  4. 2. Where our feet have taken us : Examples of human contact, migration, and adaptation as revealed by ancient DNA

    Author : Alexandra Coutinho; Mattias Jakobsson; Helena Malmström; Carina Schlebusch; Tom Gilbert; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Human demography; migration; adaptation; human contact; ancient DNA; human evolution; African prehistory; Scandinavian prehistory; Biology with Specialisation in Human Evolution and Genetics; Biologi med inriktning mot människans evolution och genetik;

    Abstract : In spite of our extensive knowledge of the human past, certain key questions remain to be answered about human prehistory. One involves the nature of cultural change in material culture through time from the perspective of how different ancient human groups interacted with one another. READ MORE

  5. 3. Ecology and evolution of large-scale bird migration patterns : A natural history and comparative study of the migration in common and little ringed plovers

    Author : Linus Hedh; Evolutionär ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ringed plover; leap-frog migration; migration speed; migration process; light level geolocator; migration;

    Abstract : Migration distance and seasonal redistribution patterns may vary between and within bird populations. A common pattern is leap-frog migration, in which northerly breeding populations migrate farther and winter south of more southerly breeding populations. READ MORE

  6. 4. The Problem of Partial Migration - the Case of the Blue Tit

    Author : Anna Nilsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Naturvetenskap; Natural science; Djurekologi; Animal ecology; Ekologi; Ecology; weather; personality; partial migration; metabolic rate; evolution of migration; dominance; Cyanistes caeruleus; climate change; blue tit; behavioural strategies; bird migration;

    Abstract : In the evolution of bird migration, partial migration is assumed to be an important intermediate step between migration and residency. Partial migration is characterised by the existence of both migratory and resident individuals in a given population. READ MORE

  7. 5. On the role of migration for the distribution of arctic birds - a circumpolar perspective

    Author : Sara Henningsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bird migration; broad-scale distributions; geographic breeding range; geography of migration; non-breeding range; barriers to migration; Arctic birds; evolution of migration routes;

    Abstract : Flexibility as well as constraints to the evolution of migration routes has the possibility of affecting large-scale patterns of geographical ranges of animals both by facilitating, but sometimes restricting, accessibility to and colonization of new regions. This dissertation concerns the broad-scale effects migration has on the distributional patterns of birds in the Arctic. READ MORE
