This type of causal and mechanistic understanding will make predictions of microbial community behavior more robust and actionable in addressing microbially mediated global problems. (frontiersin.org)
I have a particular interest in using newest development in sequencing technologies and bioinformatical analysis to gain a mechanistic understanding of microbial community function at a genome resolved level. (gfz-potsdam.de)

We also observed larger temporal variability in soil microbial community structure in Kabwe than in Lusaka. (researchsquare.com)
Systems approaches require accurate analyses of the spatio-temporal properties of the different microenvironments present in soil. (ncl.ac.uk)

Substantial enrichments of moss sequences, which are keystone taxa for soil crust development in arid regions, were detected after just 7-8 months of development. (warwick.ac.uk)

Partly decayed organic matter is called humus Components of Soil Organic Matter. (jakesonline.org)
Soil is a mix of varying amounts of inorganic matter, organic matter, water, and air. (jakesonline.org)
Very remote spaces showing a slower turnover of substrates illustrate a mechanism which may contribute to the long-term storage of organic matter in soils. (lu.se)

Our results clearly indicate distinct pattern of microbial community structure in response to forest management and time. (cyberleninka.org)
However, they also propose that there may be, in some instances, a disconnection between microbial community structure and its functions. (cyberleninka.org)
The aims of this study were to investigate the patterns of and connections between microbial community structure and microbially-mediated functions across different FMPs as a function of time. (cyberleninka.org)
This study investigated the effects of primary species groups ( Acacia , Eucalyptus ) used in shelterbelts in south-eastern Australia on soil microbial community structure in comparison with those under adjacent pastures. (ukdiss.com)
2015). Much less attention has been given to how soil bacterial and fungal community structure and function are impacted by the identity of the tree species used, or the restoration process itself (Cavagnaro et al. (ukdiss.com)
2004). One area of particular interest is the effect of plant community structure on soil microbial community structure and function (Prescott and Grayston, 2013). (ukdiss.com)
The enrichment culture can be used to study soil and sediment microbial community structure and function. (vassar.edu)

Plant rhizospheres enrich for a complex, and often consistent, subset of the bulk soil microbial reservoir. (k-state.edu)

In a multivariate regression tree analysis of soil physicochemical properties and genes detected by functional microarrays, the main factor that explained the different microbial community functional structures was C : N ratio. (hindawi.com)
Rather, the soil factors, C : N ratio, phosphate, and total N, were the main factors driving the differences in functional genes across the fields examined. (hindawi.com)

Additionally, soil pore differences across depths became exacerbated as BSCs developed over time. (warwick.ac.uk)

This release of nutrients feeds the microbial population in the soil. (highbrixgardens.com)
When rocks break down to clay and contribute their nutrients to building crops the soil slowly becomes demineralized. (highbrixgardens.com)
Soil biology, on the other hand, has access to plenty of minerals (if the soil has been remineralized) but need an energy source to liberate rock-bound nutrients. (highbrixgardens.com)
Plant roots excrete carbohydrates that feed soil biology which return the favor by making bound-up nutrients available to the plant. (highbrixgardens.com)
Provide consultancy services at national and international level to design and develop techniques for efficient use of nutrients, water, soil and other waste resources. (edu.pk)

Reduced DNA yields can significantly constrain PCR detection limits to levels inadequate for metagenomic analysis, especially from humus-rich soils. (peerj.com)

Shelterbelt systems which contain a mixture of different plant genera have the potential to exhibit greater microbial community heterogeneity than single species plantations. (ukdiss.com)

Stressed microbial community gradually adapted to the disturbance to form a new stable community. (biodiversity-science.net)
After the disturbance finished, a new stable microbial community might return to the initial community. (biodiversity-science.net)
