Here we study effects of climate and groundwater on surface-water levels, the hydrological effects on wetland water chemistry, and the combined effects of climate, hydrology, and water chemistry on plant and animal communities of prairie pothole wetlands.
Complex interactions among hydrologic events initiated by people and the behaviors and characteristics of animal species (both native and introduced) lead to important scientific and management problems.
Concerted effort to monitor, analyze, and record sightings of non-native (introduced) aquatic species throughout the United States. Explains characteristics of the database that is compiled by this program.
