Ecosystems are defined by the interactions among the plants, animals, microorganisms and abiotic, environmental features that affect them. This course will cover the flows of energy, carbon, and nutrients within ecosystems, tracing the key processes that define ecosystem function. Through the course, we will develop the connections between organisms, abiotic factors and ecosystem processes. This analysis will include a consideration of plot-level, regional and global scales. The effects of environmental change on ecosystem processes will be highlighted.
