Climate Change Impacts on Canadian Arctic Tundra Ecosystems: Interdisciplinary and Multi-scale Assessments: Spatial and Temporal Variation
Principal Investigator: Siciliano, Steven D
Licensed Year(s): 2008 2007
Summary: Tundra ecosystems are known to be strongly patterned. Understanding how these patterns control carbon and nutrient fluxes is critical to successfully modeling changes in the tundra ecosystems. The hypothesis is that the geospatial relationship between soil carbon and nitrogen cycling with community composition controls ecosystem response to global warming. To answer this, the links between various...
