Relationships Between Microbial Communities and Ecosystem Processes in High Latitude Ecosystems: Interactions that Influence Soil, Sediment, and Aquatic Processes in a Changing Cryosphere.
Session ID#: 161266
Session Description:
Microbial communities in soils, wetlands, rivers, and lakes of high latitude ecosystems are an understudied yet important component of local to global biogeochemical cycles. The cryosphere is rapidly changing, resulting in unprecedented transitions in ecosystem state and function. Because high latitude ecosystems are critical to the global carbon cycle, changing biogeochemical dynamics related to permafrost thaw, wildfire, shrubification, lake drainage, glacier retreat and other processes can have large feedbacks to climate warming. In particular, winter and shoulder season processes are an important and understudied aspect of high latitude ecosystems. The relationships between microbial and ecosystem pattern and processes that underpin large scale ecosystem change are poorly constrained, due to lack of basic ecological principles that guide understanding and lack of methodologies to study complex microbial phenomena at multiple spatial, temporal, and ecological scales. This session aims to bring together microbial ecologists and biogeochemists to synthesize our knowledge of microbial community influence on cryosphere processes under global change.
