  1. 41. Springtails in space : factors structuring Collembola populations and communities, revealed by trait-based analyses

    Författare :Lina Ahlbäck Widenfalk; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The relative influence of environmental conditions, biotic interactions and dispersal limitation for community structure and diversity patterns is a reoccurring theme in community ecology. In studies of soil fauna communities, small-scale horizontal and vertical variations in environmental variables and biotic interactions have often been disregarded, despite these being key factors to understanding the diversity of soil fauna communities.

  3. 42. Genetic structuring in natural populations - the influence of life history strategies and asymmetric migration

    Författare :Lisa Sundqvist; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Population genetics; Asymmetric migration; Genetic differentiation; Resting stages; Gene flow; Phytoplankton; Macroalgae;

    Sammanfattning : In this thesis I investigate aspects of genetic differentiation and factors influencing the structure of populations. This is done with a special focus on life histories and dispersal strategies common in the marine environment. LÄS MER

  5. 44. Genetic Structuring and the Evolution of Lekking Behaviour in the White-bearded Manakin, Manacus manacus

    Författare :Lisa Shorey; David McDonald; Uppsala universitet; []

    Sammanfattning : Genetic structuring is common in natural populations. It is important to identify and consider population structure when studying evolutionary processes. Recently, the discovery of genetic structuring in some lekking bird species has opened up new perspectives on our understanding of the evolution of lek mating systems. LÄS MER
