A Study on Bacterioplankton Community Composition in a Nature Reservoir

Applied Mechanics and Materials, 2013
The relationship between bacterioplankton community composition and environmental factors in a constructed small-scale reservoir was studied. Polymerase chain reaction (PCR) - denaturing gradient gel electrophoresis (DGGE) fingerprinting was used to detect plankton communities.

Water masses influence bacterioplankton community structure in summer Kongsfjorden

Extremophiles, 2019
To ascertain the saying "Everything is everywhere, but the environment selects", it was imperative to find out the main factor influencing bacterioplankton composition at genus level of Kongsfjorden where was influenced both by glacier melting water and Atlantic water. Thus, bacterioplankton diversity was investigated using pyrosequencing. In addition,

Bacterioplankton Community Composition in Flowing Waters of the Ipswich River Watershed

The Biological Bulletin, 2002
moptera), and the isopod Philoscia vittata were the most common invertebrates encountered in the marsh. In the marsh-grass-removal experiment we found a significant decrease in abundance of leafhoppers ( [2] 26.9, P 0.0001), as well as spiders (Order Araneae) ( [2] 8.72, P 0.013), greenhead fly larvae (Tabanus nigrovittatus) ( [2] 14.23, P 0.001), and ...

Bacterioplankton Community Variation Across River to Ocean Environmental Gradients

Microbial Ecology, 2011
Coastal zones encompass a complex spectrum of environmental gradients that each impact the composition of bacterioplankton communities. Few studies have attempted to address these gradients comprehensively. We generated a synoptic, 16S rRNA gene-based bacterioplankton community profile of a coastal zone by applying the fingerprinting technique ...

Effect of Nutrient Loading on Bacterioplankton Community Composition in Lake Mesocosms

Microbial Ecology, 2006
Changes in bacterioplankton community composition were followed in mesocosms set up in the littoral of Lake Vesijärvi, southern Finland, over two summers. Increasing nitrogen and phosphorus concentrations in the mesocosms represented different trophic states, from mesotrophic to hypertrophic.

Structuring of bacterioplankton communities by specific dissolved organic carbon compounds

Environmental Microbiology, 2012
Summary The main role of microorganisms in the cycling of the bulk dissolved organic carbon pool in the ocean is well established. Nevertheless, it remains unclear if particular bacteria preferentially utilize specific carbon compounds and whether such compounds have the potential to shape bacterial community ...

[Effects of sediment resuspension on bacterioplankton community composition].

Huan jing ke xue= Huanjing kexue, 2011
To determine the response of bacterioplankton community to sediment resuspension we set up two different intensities of the sediment resuspension in experimental microcosms. We employed the terminal restriction fragment length polymorphism (T-RFLP), denaturing gradient gel electrophoresis (DGGE) methods to characterize the bacterial community structure.

Successive changes in bacterioplankton communities in the river rhine after copper additions

Environmental Toxicology and Chemistry, 1995
Abstract The sensitivity of bacterioplankton to copper was analyzed to see whether initial steps in the selection of copper-tolerant life-forms in mixed populations of bacteria were accompanied by changes in basic metabolic parameters. Analysis took place by measuring the incorporation of [3H]thymidine and [3H]leucine, and the hydrolysis

Bacterioplankton community composition and activity in the Atlantic Ocean [PDF]

, 2007
Temporal and spatial patterns of bacterioplankton in six different provinces of the AtlanticOcean were examined between 1996 and 2004. The abundance and integrated biomassof three prokaryote groups (Prochlorococcus spp., Synechococcus spp. and heterotrophicbacteria) were used to detect standing stock changes and characterise communitystructure in the ...
