USFWS selected geographic analyses USFWS selected geographic analyses
The geographic information system (GIS) used by the National Wetlands Research Center (NWRC) of the U.S. Fish and Wildlife Service has been valuable in assisting natural resource managers in planning and managing coastal fish and wildlife resources. In the past 5 years, NWRC has conducted about 60 studies employing this technology. Applications have ranged from simple natural resource...

Estimating wintering Bald Eagle densities in the Mississippi Alluvial Valley Estimating wintering Bald Eagle densities in the Mississippi Alluvial Valley
Surveys on the winter distribution of Bald Eagles have been concentrated in the northern USA (Hastings 1988, Mattson 1988), where Bald Eagles are most common. Few density estimates for wintering Bald Eagles exist. In the past, different survey techniques with little standardization have been used. Statistical analyses and error measurements of existing winter survey data usually are not...

Global climate change: USFWS coastal research Global climate change: USFWS coastal research
Scenarios of global climate change are still ambiguous; however, increasing sea level and atmospheric carbon dioxide (CO2) concentrations seem certain, although rates of change are still being debated. Predictions for other aspects of climate change, such as temperature, tropical storm frequency and intensity, and precipitation, are still in debate, and all predictions for local (e.g...

Effects of site, landscape features, and fire regime on vegetation patterns in presettlement southern Wisconsin Effects of site, landscape features, and fire regime on vegetation patterns in presettlement southern Wisconsin
The presettlement tree cover (1831–33) of 3 townships in a southern Wisconsin landscape was analyzed using original survey records. Four forest types were identified: closed forest, open forest, savanna, and prairie. Comparisons of vegetation types and landscape pattern were made between the east and west sides of the Pecatonica River, which bisects the landscape and could have acted as...

Sensitivity of greenback cutthroat trout to acidic pH and elevated aluminum Sensitivity of greenback cutthroat trout to acidic pH and elevated aluminum
The greenback cutthroat trout Oncorhynchus clarki stomias is a threatened subspecies native to the upper South Platte and Arkansas rivers between Denver and Fort Collins, Colorado, an area also susceptible to acid deposition. In laboratory studies, we exposed this subspecies to nominal pHs of 4.5–6.5 and to nominal aluminum concentrations of 0, 50, 100, and 300 μg/L; the control was pH 6...
