High-throughput amplicon sequencing has become a well-established approach for microbial community profiling. Correlating shifts in the relative abundances of bacterial taxa with environmental

Abstract. Bacterial communities of the water and the biofilm formed during five years on an artificial substrate in Lake Baikal were studied by the pyrosequencing of 16S rRNA gene fragments; taxonomic diversity of bacterial communities and differences in their structure were revealed. All of the following statements are true concerning temperate lakes except: A) Fall and spring turnovers involve vertical mixing of temperature stratified waters. B) During fall and spring turnover, the oxygen rich hypolimnion moves up to the epilimnion. C) During late fall and early spring, a temperate lake has a uniform water temperature.

A guide to the natural history of freshwater lake bacteria. Abstract. The phylogenetic diversity of freshwater bacteria, particularly in tropical lakes, has not been thoroughly investigated. Here, we employed a cloning- and sequencing-based analysis of the 16S rRNA gene to investigate the composition of bacterial communities from the upper (UW, 0 m depth) and bottom (BW, 7 m depth) waters of a tropical unstratified freshwater lake. Freshwater lakes are bodies of still, unsalted water surrounded by land. They are usually found in low lying areas and are fed from streams, rivers and runoff from the surrounding area. Freshwater lakes provide a unique habitat for microbes because they differ from other aquatic habitats such as oceans and moving
