Spring-staging ecology of midcontinent greater white-fronted geese Spring-staging ecology of midcontinent greater white-fronted geese
A major part of the midcontinent greater white-fronted goose (Anser albifrons) population stages for several weeks in spring in the Rainwater Basin Area (RBA) of south-central Nebraska where substantial mortality from disease occurs periodically. Effective management of this population requires better data on use of habitat, vulnerability to disease, and the role of staging areas in...

Optimizing sampling effort for sampling warmwater stream fish communities Optimizing sampling effort for sampling warmwater stream fish communities
We measured the variation of some commonly used fish community attributes for two warmwater stream reaches during June–October 1992 and 1993. Habitat‐specific variation among samples, expressed as coefficients of variation (SD/mean) collected throughout the study ranged from 0.13 to 1.58 and were lower for community‐level attributes such as species richness (total number of species) and...

Ranges of North American breeding birds: visualizing long-term population changes in North American breeding birds Ranges of North American breeding birds: visualizing long-term population changes in North American breeding birds
These maps show changes in the distribution and abundance patterns of some North American birds for the last 20 years. For each species there are four maps, each representing the average distribution and abundance pattern over the five-year periods 1970-1974, 1975-1979, 1980-1984, and 1985-1989. The maps are based on data collected by the USFWS/CWS Breeding Bird Survey (BBS). Only BBS...

Conservation Reserve Program and migratory birds in the northern Great Plains Conservation Reserve Program and migratory birds in the northern Great Plains
U.S. Department of Agriculture programs have mediated supply and demand of commodities and maintained the agricultural industry, but several programs have also offered various kinds of conservation benefits. The 1985 Food Security Act (Farm Bill) featured the Conservation Reserve Program (CRP), which paid farmers to plant perennial cover on highly erodible lands and to leave this land...

The occurrence of mycoplasmas in selected wild North American waterfowl The occurrence of mycoplasmas in selected wild North American waterfowl
We determined the prevalence of mycoplasma infection in breeding mallard (Anas platyrhynchos) and canvasback (Aythya valisineria) hens and their broods from the central United States (1988 to 1990); and wintering American black duck (Anas rubripes) and mallard hens from the eastern United States (1990 to 1993). Mycoplasmas were isolated by culturing tracheal swabs from 656 live birds and...

U.S. Fish and Wildlife Service 1979 wetland classification: a review U.S. Fish and Wildlife Service 1979 wetland classification: a review
In 1979 the US Fish and Wildlife Service published and adopted a classification of wetlands and deepwater habitats of the United States. The system was designed for use in a national inventory of wetlands. It was intended to be ecologically based, to furnish the mapping units needed for the inventory, and to provide national consistency in terminology and definition. We review the...

Contributions of the Conservation Reserve Program to populations of breeding birds in North Dakota Contributions of the Conservation Reserve Program to populations of breeding birds in North Dakota
Previous studies have shown that habitat provided by the Conservation Reserve Program (CRP), a feature of the 1985 farm bill, is used by many birds. The present study quantitatively assesses the importance of the CRP by estimating changes in breeding-bird populations of North Dakota projected if CRP land would revert to cultivation. Of 18 species that were common in CRP or crop fields or...

Differential effects of coyotes and red foxes on duck nest success Differential effects of coyotes and red foxes on duck nest success
Low recruitment rates prevail among ducks in the Prairie Pothole Region of North America, primarily because of high nest depredation rates. The red fox (Vulpes vulpes) is a major predator of duck eggs, but fox abundance is depressed by coyotes (Canis latrans). We tested the hypothesis that nest success of upland-nesting ducks is higher in areas with coyotes than in areas with red foxes...

Evaluations of duck habitat and estimation of duck population sizes with a remote-sensing-based system Evaluations of duck habitat and estimation of duck population sizes with a remote-sensing-based system
During 1987-90, we used high-altitude photography, aerial videography, counts, and models to estimate sizes of breeding populations of dabbling ducks (Anatinae) and duck production and to identify duck habitat on U.S. Fish and Wildlife Service land and easements and on private land in the prairie pothole region of the United States. The study area contained about 3.1 million wetland...
