Microbial community assembly and biogeography in the Pyrenean lacustrine district

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 comm...

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 assemblagesLa metacomunidad microbiana de Pirineos nunca ha sido estudiada a nivel de región completa. En esta tesis se busca describir la diversidad taxonómica y revelar los procesos ecológicos (bióticos y abióticos) que pueden estar tras la distribución espacial y la heterogeneidad de las comunidades superficiales de lagos alpinos. Mediante un muestreo de más de 300 lagos durante el verano de 2011 y técnicas de secuenciación masiva de genes ribosómicos (16S y 18S rRNA) se obtuvieron los perfiles microbianos de comunidades de arqueas, bacterias y eucariotas. Se puso énfasis en el descubrimiento y descripción de linajes nóveles y desconocidos como Pacearchaeota o Woesearchaeota (Archaea) o Chytridiomycota (Eukarya). Se analizan el filtro ambiental y procesos de dispersión, así como las interacciones potenciales entre especies como responsables del ensamblaje de las comunidades localesUniversitat de GironaOrtega Casamayor, EmilioGuasch i Padró, HelenaUniversitat de Girona.

description 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).
