1994, Wildlife Society Bulletin (22) 576-582
During the last 4 decades, numerous studies on a variety of raptor species have described breeding success and productivity, but few studies have reported the causes of nesting failures. Newton (1979:358) described causes of nesting failures for 6 species of raptors, but only 2 of these species (bald eagle [Haliaeetus...

Effects of controlled burning of chaparral on streamflow and sediment characteristics, East Fork Sycamore Creek, central Arizona
Stanley Baldys, H. W. Hjalmarson
1994, Water-Resources Investigations Report 93-4102
The effects of controlled burning of part of a chaparral-covered drainage basin on streamflow and sediment characteristics were studied in the upper reaches of the Sycamore Creek basin in central Arizona. A paired-watershed method was used to analyze data collected in two phases separated by the controlled burning of 45...

In 1991, the U.S. Geological Survey (USGS) began its National Water-Quality Assessment (NAWQA ) program to (1) document the quality of a large, representative part of the Nation's water resources; (2) define water-quality trends; and (3) identify major factors that affect water quality. In addressing these goals, the program will...

An individual-based model (IBM) was applied to the Lake Michigan rainbow trout (Oncorhynchus mykiss) population, with the objectives of explaining the observed variation in growth and in polychlorinated biphenyl (PCB) concentration within the population. When variation in prey PCB concentration was incorporated into the model, variability in PCB concentration among...

1994, Journal of Wildlife Management (58) 100-106
A wetland in central Arkansas was contaminated with polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans and because the area was a major waterfowl habitat, we studied the effects of the contamination on nesting wood ducks (Aix sponsa) during 1988-90. Residues in wood duck eggs, based on toxicity equivalency factors (TEFs) for combined...
