Abstract Background Rhizosphere microbial communities are key regulators of plant performance, yet few studies have assessed the impact different management approaches on rhizosphere microbiomes major crops. shaped by interactions between agricultural and host selection processes, but often consider these factors individually rather than in combination. We tested impacts (M) effects (R) community structure co-occurrence networks maize roots collected from long-term conventionally organically...
ABSTRACT Culture-independent DNA fingerprints are commonly used to assess the diversity of a microbial community. However, relating species composition community profiles produced by fingerprint methods is not straightforward. Terminal restriction fragment length polymorphism (T-RFLP) method in which phylogenetic assignments may be inferred from terminal (T-RF) sizes through use web-based resources that predict T-RF for known bacteria. The process quickly becomes computationally intensive...
We investigated patterns of intra‐ and interannual change in pelagic bacterial community composition (BCC, assessed using automated ribosomal intergenic spacer analysis) over six years eutrophic Lake Mendota, Wisconsin. A regular phenology was repeated across years, implying that freshwater communities are more predictable their dynamics than previously thought. Seasonal events, such as water column mixing trends temperature, were most strongly related to BCC variation. Communities became...
Background Giardia duodenalis is prevalent in tropical settings where diverse opportunities exist for transmission between people and animals. We conducted a cross-sectional study of G. people, livestock, wild primates near Kibale National Park, Uganda, human-livestock-wildlife interaction high due to habitat disturbance. Our goal was infer the cross-species potential using molecular methods investigate clinical consequences infection. Methodology/Principal Findings Real-time PCR on DNA...
ABSTRACT Wetland mitigation is implemented to replace ecosystem functions provided by wetlands; however, restoration efforts frequently fail establish equivalent levels of services. Delivery microbially mediated functions, such as denitrification, influenced both the structure and activity microbial community. The objective this study was compare relationship between soil vegetation factors community function in restored reference wetlands within a bank. Microbial composition assessed using...
ABSTRACT In all mammals, growth, development, pregnancy, and lactation increase nutritional demands. Although primate field studies tend to focus on shifts in activity diet as mechanisms compensate for these demands, differences digestive efficiency also are likely be important. Because the gut microbiota can impact host efficiency, we examined budget, diet, microbial community among adult male ( N = 4), female juvenile 5) wild black howler monkeys Alouatta pigra ) across a ten‐month period...
Abstract Recruitment of microorganisms to the rhizosphere varies among plant genotypes, yet an understanding whether microbiome can be altered by selection on host is relatively unknown. Here, we performed a common garden study characterize recruitment microbiome, functional groups, for 20 expired Plant Variety Protection Act maize lines spanning chronosequence development from 1949 1986. This time frame brackets series agronomic innovations, namely improvements in breeding and application...
In an effort to better understand the factors contributing patterns in freshwater bacterioplankton community composition and diversity, we coupled automated ribosomal intergenic spacer analysis (ARISA) of 16S RNA (rRNA) gene sequences follow persistence 46 individual phylotypes over 3 years Crystal Bog Lake. Additionally, sought identify linkages between observed phylotype variations known chemical biological drivers. Sequencing rRNA genes obtained from water column indicated presence...
Time-series observations and a phytoplankton manipulation experiment were combined to test the hypothesis that succession effects changes in bacterial community composition. Three humic lakes sampled weekly May-August correlations between relative abundances of specific operational taxonomic units (OTUs) each time series determined. To experimentally characterize influence phytoplankton, bacteria from lake incubated with one three or no phytoplankton. Following incubation, variation...
The cyanobacterial community colonizing phyllosphere in a well-preserved Brazilian mangrove ecosystem was assessed using cultivation-independent molecular approaches. Leaves of trees that occupy this environment (Rhizophora mangle,Avicennia schaueriana and Laguncularia racemosa) were collected along transect beginning at the margin bay extending upland. results demonstrated R. mangle L. racemosa harbor similar assemblages cyanobacteria each point transect. A. schaueriana, found only coastal...
Abstract Although elevated CO 2 ( eCO ) significantly affects the α ‐diversity, composition, function, interaction and dynamics of soil microbial communities at local scale, little is known about impacts on geographic distribution micro‐organisms regionally or globally. Here, we examined β ‐diversity 110 across six free air enrichment FACE experimental sites using a high‐throughput functional gene array. The was P < 0.05) correlated with distance under both conditions, but declined faster...
