Activities
I am examining how freshwater communities respond to anthropogenic influenences across different spatial and temporal scales. I am especially concerned with interactions in watersheds and catchments as they affect the riparian zones and in-streamprocesses. The present concerns are associated with de-forestation, introduction of alien species, livestock grazing, and mining as it affects (1) temperature, (2) organic inputs into streams, (3) shade and riparian canopy cover, (4)hyporheic and lateral groundwater connectivity from the riparian zone to the stream channel. I work in a team where we are attempting to use the combination of remote sensed information and field study to determine how ecosystem function (e.g., community structure, population structure (genetics and physiology), trophic web, nutrient cycling, stream flow dynamics) is affected by these activities.
