    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Resource polymorphism; phenotypic plasticity; phenotypic divergence; anti-predator responses; Perca fluviatilis; Rutilus rutilus; Dreissena polymorpha; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

    Sammanfattning : Individuals within a single population can vary widely in their phenotype e.g. in their body shape. These differences are an important source of biodiversity and they can precede evolutionary divergence within a population. LÄS MER

  2. 2. Ecological and evolutionary effects of predation in environmental gradients

    Författare :Gunnar Öhlund; Göran Englund; Skuli Skulason; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Understanding species interactions and how they affect densities and distributions of organisms is a central theme in ecological research. Studying such interactions in an ecosystem context is challenging as they often depend on species-specific characteristics and rates that not only change during the ontogeny of an organism, but also are affected by the surrounding environment.
