DUGiDocsMicrobial community assembly and biogeography in the Pyrenean lacustrine district
Text Complet
The microbial metacommunity of the Pyrenees mountain range has never been studied at the regional level. In this PhD thesis, the main goal is to describe the taxonomic diversity and reveal the ecological processes (biotic and abiotic) behind the spatial distribution and heterogeneity of surface communities of alpine lakes. With a sampling of more than 300 lakes during summer of 2011 and high-througput sequencing of ribosomal markers (16S and 18S rRNA), we analized the microbial profiles of archaeal, bacterial and eukaryotic communities. We highlighted the discovery and description of novel and unknown lineages such as Pacearchaeota or Woesearchaeota (Archaea) or Chytridiomycota (Eukarya). We analyzed the role of environmental filtering and dispersal processes, as well as potential species interactions as drivers of local community assemblages
