Contact Admin. Our study aims to determine active microbial community structure changes within different aquatic sites and its relationship with environmental factors and viruses as potential drivers of diversification in different aquatic areas of this ecosystem.
In this study, bacteria and archaea composition 16S rRNA subunit pyrolibraries and picoplankton and viral abundance were determined at ponds, springs and lagoon sites of the wetland during wet and dry seasons February and July , respectively.
Viral abundance and viral to picoplankton ratio VPR also presented greater values at ponds compared to spring sites, reaching up to 4. A greater richness of archaea was also detected in ponds characterized by functional groups such as known methanogens and ammonia oxidizers, and uncultured groups. The wet season occurs during austral summer DecemberβFebruary , which presents high cloud coverage and intense precipitation including snowfall Garreaud, Former results show high microbial diversity, which in terms of bacterioplankton are dominated by the phylum Bacteroidetes, Proteobacteria, Crenarchaeota, Actinobacteria, among others e.
In this paper, we examine the composition of the active microbial community present in different aquatic environments of Salar de Huasco such as spring, ponds, and the main lagoon including sites with higher microbial complexity like ponds with microbial mats, during different periods wet and dry season using pyrosequencing of 16S rRNA, to recover most of the variability in this ecosystem.
Sampling took place in Salar de Huasco, Chile, during February and July of , corresponding to wet and dry season, respectively, to cover different sources of variability in the aquatic ecosystems explored, associated with climatic conditions.
