The activity of marine microorganisms depends on community composition, yet, in some oceans, little is known about the environmental and ecological processes that structure their distribution. The objective of this study was to test the effect of geographic distance and environmental parameters on prokaryotic community structure in the Southern Ocean (SO). We described the total (16S rRNA gene) and the active fraction (16S rRNA-based) of surface microbial communities over a ~6.500 km longitudinal transect in the SO. We found that the community composition of the total fraction was different from the active fraction across the zones investigated. In addition, higher α-diversity and stronger species turnover were displayed in the active community compared to the total community. Oceanospirillales, Alteromonadales, Rhodobacterales and Flavobacteriales dominated the composition of the bacterioplankton communities, however, there were marked differences at the order level.

BYERS PENINSULA, Antarctica A team of Spanish researchers has detected microplastics in freshwater in Antarctica, indicating the particles are spreading to places virtually untouched by man.
The recent investigation, led by scientists from the Autonomous University of Madrid and Alcala University, confirmed the presence of polyester, acrylic and Teflon in the glacier-fed waters of the Byers Peninsula on Livingston Island.
“This area is a protected area since 1966, and only scientists are allowed to go there and only after filing a lot of paperwork,” Roberto Rosal Garcia, a professor at the University of Alcala, told Zenger News in an exclusive interview.
