An ecological study of waterfowl on artificial impoundments in southern Alberta / Lloyd B. Keith
Material type:
TextSeries: Thesis ; (M.Sc.)Publication details: Edmonton, AB : University of Alberta, 1955.Abstract: During the period from May to August inclusive, 1953 and 1954, studies in waterfowl ecology were conducted on the short grass prairie near Brooks, Alberta. A group of artificial impoundments constructed by Ducks Unlimited was chosen as the study area. Investigation and analyses of aquatic and terrestrial vegetation, soils, predation, nesting cover,population dynamics, and food habits were undertaken to ascertain waterfowl preferences and other factors affecting duck production.Vegetative studies disclosed three terrestrial plant communities in the study area, viz., the short grass prairie association, the Juncus community, and the Hordeum community. These were cover- mapped, and quadrats analyzed from each yielded information on species dominance,the effect of grazing, and the potential nest cover. A survey of aquatic vegetation indicated the presence of a rich and diverse flora. What are believed the first Alberta records of Ruppia occidentalis and Elodea canadensis were found her
