| Abstract | Structuring of bacterioplanktonic populations and factors that determine the structuring of specific niche partitions have
been demonstrated only for a limited number of colder water environments. In order to better understand the physical
chemical and biological parameters that may influence bacterioplankton diversity and abundance, we examined their
productivity, abundance and diversity in the second largest Brazilian tropical bay (Guanabara Bay, GB), as well as seawater
physical chemical and biological parameters of GB. The inner bay location with higher nutrient input favored higher
microbial (including vibrio) growth. Metagenomic analysis revealed a predominance of Gammaproteobacteria in this
location, while GB locations with lower nutrient concentration favored Alphaproteobacteria and Flavobacteria. According to
the subsystems (SEED) functional analysis, GB has a distinctive metabolic signature, comprising a higher number of
sequences in the metabolism of phosphorus and aromatic compounds and a lower number of sequences in the
photosynthesis subsystem. The apparent phosphorus limitation appears to influence the GB metagenomic signature of the
three locations. Phosphorus is also one of the main factors determining changes in the abundance of planktonic vibrios,
suggesting that nutrient limitation can be observed at community (metagenomic) and population levels (total prokaryote
and vibrio counts). | pt_BR |
