    This study investigated the spatial variation in the components of a microbial food web (viruses, picoplankton, nanoflagellates, and ciliates) in different hydrographic environments in the Taiwan Strait during winter. Water temperature and salinity varied spatially, with lower temperatures (– °C) and salinities (– psu) in the northern part of the Taiwan Strait, largely.

Bacterioplankton community composition, production, and abundance vary seasonally in most freshwater systems where temporal patterns have been examined, and these variations appear to track climatic variations that affect numerous biogeochemical processes.

Protistan size-selective grazing on aquatic bacteria has frequently been demonstrated in the laboratory, but its postulated effects on the size distribution of natural bacterioplankton communities.

Bacterial community structure has been shown to be altered by bacterivory (Simek et al., ; Suzuki, ), to change during the aging of laboratory-made aggregates (Grossart and Ploug, ) and during long-term (8–10 days) incubations (Massana et al., ).

Our results demonstrate that it also changes during shorter. The effect of signal compounds and of different incubation conditions on the culturability (i.e., the fraction of all cells capable of growth) of natural bacterioplankton from the eutrophic lake Zwischenahner Meer was investigated over a period of 20 months.

Bacterioplankton counting is the estimation of the abundance of bacterioplankton in a specific body of water, which is useful information to marine microbiologists. Various counting methodologies have been developed over the years to determine the number present in the water being observed.

Bacterioplankton refers to the bacterial component of the plankton that drifts in the water column. The name comes from the Ancient Greek word πλανκτος (planktos), meaning "wanderer" or "drifter", and bacterium, a Latin term coined in the 19th century by Christian Gottfried are found in both seawater and freshwater.

Bacterioplankton occupy a range of ecological niches. Peter, H., Jeppesen, E., De Meester, L. et al. Changes in bacterioplankton community structure during early lake ontogeny resulting from the retreat of the Greenland Ice Sheet. Bacterioplankton definition is - plankton composed of bacteria.

How to use bacterioplankton in a sentence. Fjords and open oceans are two typical marine ecosystems in the Arctic region, where glacial meltwater and sea ice meltwater have great effects on the bacterioplankton community structure during the summer season.

This study aimed to determine the differences in bacterioplankton communities between these two ecosystems in the Arctic region. We conducted a detailed census of. A field study over an annual cycle in a shallow, wetland pond dominated by Nymphaea odorata was combined with laboratory experiments to determine the fate of DOM from aquatic macrophyte primary productivity in the microbial food web.

DOM concentrations, bacterial abundance and productivity, and protistan abundance were more than an order of magnitude higher during warm months (water. Effect of nutrient enrichment on bacterioplankton biomass and community composition in mesocosms in the Archipelago Sea, northern Baltic.

Both surface ( m) and bottom (3–45 m) water samples were collected from Shenhu Bay (stations 1, 2, and 3) in MayDongshan Bay (stations 4, 5, and 6) in August.The phylogenetic composition and leucine-uptake of bacterioplankton was more markedly affected by resource availability than by grazing pressure, which only had a strong effect on the dynamics of R-BT bacteria within the P-limited area of the reservoir.Microbes are considered to have a global distribution due to their high dispersal capabilities.

However, our knowledge of the way geographically distant microbial communities assemble after dispersal in a new environment is limited.

In this study, we examined whether communities would converge because similar taxa would be selected under the same environmental conditions, or would diverge.
