Temporal variability in the diversity and composition of stream bacterioplankton communities

Environmental Microbiology, 2012
Summary Bacterioplankton in freshwater streams play a critical role in stream nutrient cycling. Despite their ecological importance, the temporal variability in the structure of stream bacterioplankton communities remains understudied.

Bacterioplankton: A Sink for Carbon in a Coastal Marine Plankton Community

Science, 1986
Recent determinations of high production rates (up to 30 percent of primary production in surface waters) implicate free-living marine bacterioplankton as a link in a "microbial loop" that supplements phytoplankton as food for herbivores. An enclosed water column of 300 cubic meters was used to test the microbial loop hypothesis by following the fate ...

SAR11 clade dominates ocean surface bacterioplankton communities

Nature, 2002
The most abundant class of bacterial ribosomal RNA genes detected in seawater DNA by gene cloning belongs to SAR11-an alpha-proteobacterial clade. Other than indications of their prevalence in seawater, little is known about these organisms. Here we report quantitative measurements of the cellular abundance of the SAR11 clade in northwestern Sargasso ...

Global patterns of diversity and community structure in marine bacterioplankton

Molecular Ecology, 2007
Abstract Because of their small size, great abundance and easy dispersal, it is often assumed that marine planktonic microorganisms have a ubiquitous distribution that prevents any structured assembly into local communities. To challenge this view, marine bacterioplankton communities from coastal waters at nine locations distributed ...

Bacterioplankton diversity and community composition in the Southern Lagoon of Venice

Systematic and Applied Microbiology, 2010
The Lagoon of Venice is a large water basin that exchanges water with the Northern Adriatic Sea through three large inlets. In this study, the 16S rRNA approach was used to investigate the bacterial diversity and community composition within the southern basin of the Lagoon of Venice and at one inlet in October 2007 and June 2008.

Inoculation history affects community composition in experimental freshwater bacterioplankton communities

Environmental Microbiology, 2018
Summary Priority effects occur when the arrival order of species or genotypes has a lasting effect on community or population structure. For freshwater bacteria , priority effects have been shown experimentally among individual species, but no experiments have been performed

Bacterioplankton community indicators for seasonal variation in a fragmented subtropical river

Environmental Monitoring and Assessment, 2022
In this study, spatiotemporal investigations were conducted along five cascade dams in the main channel of the North River of China during 2019 to explore bacterioplankton community indicators of water environments in a fragmented, highly regulated river.

Marine Bacterioplankton Diversity and Community Composition in an Antarctic Coastal Environment

Microbial Ecology, 2011
The bacterial community inhabiting the water column at Terra Nova Bay (Ross Sea, Antarctica) was examined by the fluorescent in situ hybridization (FISH) technique and the genotypic and phenotypic characterization of 606 bacterial isolates. Overall, the FISH analysis revealed a bacterioplankton composition that was typical of Antarctic marine ...

Impact of light on marine bacterioplankton community structure

Aquatic Microbial Ecology, 2005
Reports of widespread proteorhodopsin and bacteriochlorophyll a genes suggest that light may facilitate the growth of many marine bacteria. We tested this hypothesis by conducting 3 light manipulation experiments with bacterial communities obtained off the Southern California coast.
