    Abstract : In this thesis, I try to proceed one step further towards an understanding of the biogeographic processes forming the distribution patterns of organisms that we see today. Babblers and warblers are diverse groups of passerines that are phylogenetically intermixed with other groups in the superfamily Sylvioidea. READ MORE

  7. 5. Factors influencing the biogeography of bacteria in fresh waters - a metacommunity approach

    Author : Jürg Brendan Logue; Eva S. Lindström; Silke Langenheder; Lars Tranvik; Byron Crump; Uppsala universitet; []

    Abstract : One of ecology’s primary goals is to comprehend biodiversity and its patterns of distribution over space and time. Since microorganisms play a pivotal role in key ecological processes, the diversity of microbial communities may have important implications for the stability and functioning of Earth’s ecosystems.
