Do interactions of land use and climate affect productivity of waterbirds and prairie-pothole wetlands?
Michael J. Anteau
2012, Wetlands (32) 1-9
Availability of aquatic invertebrates on migration and breeding areas influences recruitment of ducks and shorebirds. In wetlands of Prairie Pothole Region (PPR), aquatic invertebrate production primarily is driven by interannual fluctuations of water levels in response to wet-dry cycles in climate. However, this understanding comes from studying basins that are...
