Land use change alters functional gene diversity, composition and abundance in Amazon forest soil microbial communities.
Land use change in the Amazon rainforest alters the taxonomic structure of soil microbial communities, but whether it alters their functional gene composition is unknown. We used the highly parallel microarray technology GeoChip 4.0, which contains 83,992 probes specific for genes linked nutrient cycling and other processes, to evaluate how the diversity, abundance and similarity of the targete...
متن کاملLand-use types and soil chemical properties influence soil microbial communities in the semiarid Loess Plateau region in China
Similar land-use types usually have similar soil properties, and, most likely, similar microbial communities. Here, we assessed whether land-use types or soil chemical properties are the primary drivers of soil microbial community composition, and how changes in one part of the ecosystem affect another. We applied Ion Torrent sequencing to the bacterial and fungal communities of five different ...
متن کاملColonization patterns of soil microbial communities in the Atacama Desert
BACKGROUND The Atacama Desert is one of the driest deserts in the world and its soil, with extremely low moisture, organic carbon content, and oxidizing conditions, is considered to be at the dry limit for life. RESULTS Analyses of high throughput DNA sequence data revealed that bacterial communities from six geographic locations in the hyper-arid core and along a North-South moisture gradien...
متن کاملStructure and function of alpine and arctic soil microbial communities.
Cultivation-independent molecular phylogenetic techniques are now widely employed to examine environmental microbial diversity; however, the relationship between microbial community structure and ecosystem function is unclear. This review synthesizes cultivation-independent views of microbiological diversity with our current understanding of nutrient dynamics in alpine and arctic soils. Recentl...
متن کاملAnthropogenic land use shapes the composition and phylogenetic structure of soil arbuscular mycorrhizal fungal communities.
Arbuscular mycorrhizal (AM) fungi play an important role in ecosystems, but little is known about how soil AM fungal community composition varies in relation to habitat type and land-use intensity. We molecularly characterized AM fungal communities in soil samples (n = 88) from structurally open (permanent grassland, intensive and sustainable agriculture) and forested habitats (primeval forest ...
