Predicting spatial patterns of soil bacteria under current and future environmental conditions.

摘要: Soil bacteria are largely missing from future biodiversity assessments hindering comprehensive forecasts of ecosystem changes. bacterial communities expected to be more strongly driven by pH and less other edaphic climatic factors. Thus, alkalinisation or acidification along with climate change may influence soil bacteria, subsequent influences for example on nutrient cycling vegetation. Future therefore needed. We applied species distribution modelling (SDM) quantify the roles environmental factors in governing spatial abundance OTUs predict how changes these a temperate mountain area. Models indicated that related (especially pH), and/or topography explain part most OTUs. This supports expectations microorganisms have specific requirements (i.e., niches/envelopes) they should accordingly respond Our predictions indicate stronger role over predictors (e.g. climate) distributions yet predicted smaller than their current variation across space. The extent community varies as function elevation, but general, deviations neutral decrease abundances diversity bacteria. findings highlight need account changes,
