Randomized lasso links microbial taxa with aquatic functional groups inferred from flow cytometry [PDF]

, 2019
High-nucleic-acid (HNA) and low-nucleic-acid (LNA) bacteria are two operational groups identified by flow cytometry (FCM) in aquatic systems. A number of reports have shown that HNA cell density correlates strongly with heterotrophic production, while ...

Biogeographic patterns of abundant and rare bacterioplankton in three subtropical bays resulting from selective and neutral processes

The ISME Journal, 2018
Unraveling the relative importance of ecological processes regulating microbial community structure is a central goal in microbial ecology. Here, we used high-throughput sequencing to examine the relative contribution of selective and neutral processes ...

Biogeographical diversity among marine bacterioplankton [PDF]

Aquatic Microbial Ecology, 2000
The phylogenetic diversity of bacteria isolated on solid media from the Baltic Sea, Mediterranean Sea, Southern CaMornia Bight, Skagerrak, Weddell Sea (ice) and Andaman Sea was investigated by means of 16s rRNA gene sequence analysis. Of the 128 sequenced isolates, 5 2 % showed similarity on the species level to previously reported bacteria, while as ...

Particle-Associated Bacterioplankton Communities Across the Red Sea. [PDF]

Environ Microbiol
ABSTRACT Pelagic particle‐associated bacterioplankton play crucial roles in marine ecosystems, influencing biogeochemical cycling and ecosystem functioning. However, their diversity, composition, and dynamics remain poorly understood, particularly in unique environments such as the Red Sea.

Determinants of bacterioplankton structures in the typically turbid Weihe River and its clear tributaries from the northern foot of the Qinling Mountains

Ecological Indicators, 2021
The Weihe River is the largest tributary of the typically sediment-laden Yellow River in China. Assuming that high sediment concentrations may increase the turbidity of water bodies, and therefore affect riverine ecosystem, in which the bacterioplankton ...

Spatial and temporal dynamics of bacterioplankton community composition in a subtropical dammed karst river of southwestern China

MicrobiologyOpen, 2019
River damming influences the hydro‐physicochemical variations in karst water; however, such disruption in bacterioplankton communities has seldom been studied.

Effects of Glyphosate on the Planktonic Microbiota: An Experimental Approach

Environmental Toxicology, EarlyView.
ABSTRACT Glyphosate is one of the most widely used herbicides in the world, including in Brazil, and its dispersion through habitats and surface waters can impact entire aquatic ecosystems. However, experimental studies evaluating the effects of pesticides on whole planktonic communities, considering attributes such as richness, density and composition—

The Employment of Hydrogen Peroxide in Water Disinfection Poses a Threat to Aquatic Ecosystems Because of Its Toxicity to Nontarget Organisms

Environmental Toxicology, EarlyView.
ABSTRACT Hydrogen peroxide is widely used in water and wastewater treatment, particularly in advanced oxidation processes that aid in the degradation of compounds and microbial disinfection. Despite concerns about potential environmental contamination, its impact on freshwater ecosystems remains inadequately studied.

Impact of UV Radiation on Bacterioplankton Community Composition [PDF]

Applied and Environmental Microbiology, 2001
ABSTRACT The potential effect of UV radiation on the composition of coastal marine bacterioplankton communities was investigated. Dilution cultures with seawater collected from the surface mixed layer of the coastal North Sea were exposed to different ranges of natural or artificial solar radiation for up to two diurnal cycles ...
