Contrasting factors drive within-lake bacterial community composition and functional traits in a large shallow subtropical lake

Contrasting factors drive within-lake bacterial community composition and functional traits in a large shallow subtropical lake

Lakes are considered as “islands” for assessing microbial biogeography, but bacterial community composition (BCC) and function may vary significantly within lakes, with the roles of scale and connectivity still unclear. This study investigated the spatial and temporal heterogeneity of the BCC (a...

Description
Summary:Lakes are considered as “islands” for assessing microbial biogeography, but bacterial community composition (BCC) and function may vary significantly within lakes, with the roles of scale and connectivity still unclear. This study investigated the spatial and temporal heterogeneity of the BCC (automated ribosomal intergenic spacer analysis) and functional traits (FT, carbon-source utilization), and the contribution of: (i) environmental variables, (ii) phytoplankton, (iii) season, and (iv) space, through variance partitioning in the large and well-mixed Lake Mangueira. The BCC and FT differed in time and space, with BCC being explained by environmental variables and phytoplankton, whereas FT was explained only by space. The smallest scale of variability detected by the BCC and FT (
