Microbial control over carbon cycling in soil
A major thrust of terrestrial microbial ecology is focused on understanding when and how the composition of the microbial community affects the functioning of biogeochemical processes at the ecosystem scale (meters-to-kilometers and days-to-years). While research has demonstrated these linkages for physiologically and phylogenetically "narrow" processes such as trace gas emissions and nitrifica...

متن کاملElevated carbon dioxide accelerates the spatial turnover of soil microbial communities.
Although elevated CO2 (eCO2 ) significantly affects the α-diversity, composition, function, interaction and dynamics of soil microbial communities at the local scale, little is known about eCO2 impacts on the geographic distribution of micro-organisms regionally or globally. Here, we examined the β-diversity of 110 soil microbial communities across six free air CO2 enrichment (FACE) experimenta...
متن کاملElevated carbon dioxide alters the structure of soil microbial communities.
Pyrosequencing analysis of 16S rRNA genes was used to examine impacts of elevated CO(2) (eCO(2)) on soil microbial communities from 12 replicates each from ambient CO(2) (aCO(2)) and eCO(2) settings. The results suggest that the soil microbial community composition and structure significantly altered under conditions of eCO(2), which was closely associated with soil and plant properties.
متن کاملModeling soil microbial dynamics in carbon and nitrogen cycling
Goal To determine the relative importance of different mechanisms that influence carbon loss from soil under variable soil-moisture conditions. The soil contains more carbon than the atmosphere and plants combined (Scurlock and Hall 1998). This carbon is important for maintaining soil fertility, controlling erosion, and the long-term storage of carbon that could be released into the atmosphere....
