Zooplankton-mediated changes of bacterial community structure

Microbial Ecology, 1994
Enclosure experiments in the mesotrophic Schöhsee in northern Germany were designed to study the impact of metazooplankton on components of the microbial food web (bacteria, flagellates, ciliates). Zooplankton was manipulated in 500-liter epilimnetic mesocosms so that either Daphnia or copepods were dominating, or metazooplankton was virtually absent ...

Structure of epiphytic bacterial communities of weeds

Microbiology, 2017
Dynamics of the taxonomic structure of epiphytic bacterial communities of the rhizosphere and phyllosphere of seven weed species was studied. The major types of isolated organisms were identified using phenotypic and molecular biological approaches.

Bacterial community structure in fumigated soil

Soil Biology and Biochemistry, 2014
Abstract Soil microbial biomass has been determined since the mid 1970's by the chloroform fumigation incubation technique as proposed by Jenkinson and Powlson (1976). The microbial biomass C can be determined by subtracting the CO2 emitted from an unfumigated soil (mineralization of soil organic matter) from that emitted from a chloroform fumigated ...

Anthropogenic disturbance affects the structure of bacterial communities

Environmental Microbiology, 2010
Summary Patterns of taxa abundance distributions are the result of the combined effects of historical and biological processes and as such are central to ecology. It is accepted that a taxa abundance distribution for a given community of animals or plants following a perturbation will typically change in structure from one of high ...

Structure of bacterial communities in diverse freshwater habitats

Canadian Journal of Microbiology, 2012
The structures and dynamics of bacterial communities from raw source water, groundwater, and drinking water before and after filtration were studied in four seasons of a year, with culture-independent methods. Genomic DNA from water samples was analyzed by the polymerase chain reaction – denaturing gradient gel electrophoresis system and by cloning of ...

Evidence for selective bacterial community structuring on microplastics

Environmental Microbiology, 2018
Summary In aquatic ecosystems, microplastics are a relatively new anthropogenic substrate that can readily be colonized by biofilm‐forming organisms. To examine the effects of substrate type on microbial community assembly, we exposed ambient Baltic bacterioplankton to plastic substrates commonly found in marine environments ...

Plant community richness and microbial interactions structure bacterial communities in soil

Ecology, 2015
Plant species, plant community diversity and microbial interactions can significantly impact soil microbial communities, yet there are few data on the interactive effects of plant species and plant community diversity on soil bacterial communities. We hypothesized that plant species and plant community diversity affect soil bacterial communities by ...
