1. 1. Modelling spatial and temporal species distribution in the Baltic Sea phytobenthic zone

   Författare :Antonia Nyström Sandman; Hans Kautsky; Martin Isaeus; Georg Martin; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; species distribution modelling; niche; gradient; prediction; environmental factors; phytobenthos; scale; Marine ecology; Marin ekologi; Marine Ecology; marin ekologi;

   Sammanfattning : Statistical modelling is often used to relate the presence or abundance of species to environmental predictors, thereby providing a basis for predictive mapping of species or biodiversity. The variables included must thus be relevant and reflect actual changes in the environment. LÄS MER

3. 2. Factors structuring Fucus communities at open and complex coastlines in the Baltic Sea

   Författare :Martin Isaeus; Lena Kautsky; Johan Ehrlén; Stein Fredriksen; Stockholms universitet; []
   Nyckelord :Botany;

   Sammanfattning : This thesis deals with physical factors and biological interactions affecting the distribution of two fucoid species, Fucus vesiculosus and F. serratus, in the Baltic Sea. Studies have been carried out in two quite different environments: an archipelago, and an open rocky coast. LÄS MER
