Full title

Microbial responses to increased moisture and nutrient resources in the McMurdo Dry Valleys of Antarctica

Abstract

The McMurdo Dry Valleys (MDV) are currently experiencing climate-induced changes including increased moisture and nutrient availability which are likely to intensify in the near future. We hypothesize that these changes will amplify connectivity among landscape units leading to enhanced coupling of nutrient cycles across landscapes, and increased biodiversity and productivity within the ecosystem. Results from experimental work suggest MDV lake and soil microbial communities may undergo rapid biogeochemical and biodiversity changes in response to increased resources. Our results will be discussed in the context of anticipated future climatic scenarios.
