  1. 1. Evolution of Ecological Communities in Spatially Heterogeneous Environments

    Författare :Jonas Wickman; Åke Brännström; Sebastian Diehl; Mathew A Leibold; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Spatial models; reaction-diffusion equations; eco-evolutionary models; adaptive dynamics; evolutionarily stable communities;

    Sammanfattning : Evolutionarily stable communities are the endpoints of evolution, and ecological communities whose traits are under selection will eventually settle into them. Hence, the properties of such communities are of particular interest, as they can persist over long evolutionary time scales. LÄS MER

  2. 2. Population-level consequences of spatial interactions

    Författare :Henrik Sjödin; Göran Englund; Åke Brännström; Per Lundberg; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : How is the nature of populations governed by the movement decisions made by their members? This is the core question in this thesis. To answer this question, I first assume that s movement decisions are based on conditions in their local environment. LÄS MER

  3. 3. Evolution of Plants : a mathematical perspective

    Sammanfattning : The Earth harbors around 300 000 plant species. The rich and complex environment provided by plants is considered a key factor for the extraordinary diversity of the terrestrial fauna by, for example, providing food and shelter. LÄS MER
