Waterfowl-macrophyte interactions: implications for conservation of freshwater ecosystems / Adrienne J. Froelich

By: Material type: TextTextSeries: Thesis ; (Ph.D.)Publication details: Notre Dame, IN : University of Notre Dame, 2001.Description: xiii, 177 p. : ill. ; 28 cmAbstract: The physical, chemical and biological environment of aquatic habitats is strongly affected by vascular plants. Any factor that affects the species composition or biomass of aquatic macrophytes will thus have indirect effects on the other components of the food web. Many species of waterfowl are dependent on aquatic plants during the winter. Because the reproductive success and annual survival of waterfowl is influenced by food availability on the wintering grounds, it is important to understand the factors that regulate the standing stock and diversity of vascular plants in wintering habitat.
