Effects of the herbicide atrazine on Ambystoma tigrinum metamorphosis: duration, larval growth, and hormonal response Effects of the herbicide atrazine on Ambystoma tigrinum metamorphosis: duration, larval growth, and hormonal response
We exposed larval tiger salamanders (Ambystoma tigrinum) reared in the laboratory from eggs collected from a prairie wetland in North Dakota to three concentrations of atrazine (0, 75, and 250 i??g/L) in a static renewal test to determine the pesticide's effect on (1) plasma corticosterone and thyroxine concentrations, (2) larval size, and (3) days-to-stage at stages 2 and 4 of...

Response of nesting ducks to predator exclosures and water conditions during drought Response of nesting ducks to predator exclosures and water conditions during drought
We investigated whether small predator exclosures might be a useful tool for increasing duck recruitment. During a period of increasing drought from 1987 to 1991, we monitored populations of dabbling ducks on 9 51-km2 study areas, 3 of which contained a centrally located 25-ha predator exclosure and 3 of which served as control areas. We did not detect an increase in duck pairs per...

Effects of management practices on grassland birds: Marbled Godwit Effects of management practices on grassland birds: Marbled Godwit
Information on the habitat requirements and effects of habitat management on grassland birds were summarized from information in more than 5,500 published and unpublished papers. A range map is provided to indicate the relative densities of the species in North America, based on Breeding Bird Survey (BBS) data. Although birds frequently are observed outside the breeding range indicated...

Effects of food supplementation on depredation of duck nests in prairies by striped skunks Effects of food supplementation on depredation of duck nests in prairies by striped skunks
We examined provision of supplemental food as a method for reducing depredation of upland-duck nests, especially by striped skunks (Mephitis mephitis). Predators negatively influence duck recruitment in grassland ecosystems. Managers are in search of methods, particularly nonlethal methods, for reducing nest depredation. We conducted this study on 24 areas managed for wildlife production...

Professionals in environmental education: Helping kids learn about forestry Professionals in environmental education: Helping kids learn about forestry
A K--8 school in a suburb of St. Paul has formed a partnership with natural resource professionals to create a school forest for environmental education in the field. The university and agency professionals worked with students to teach them the skills necessary to map and inventory their school grounds. Students then used the inventory data to develop a school forest plan. Over the past...

Causes and rates of mortality of swift foxes in western Kansas Causes and rates of mortality of swift foxes in western Kansas
Knowledge of mortality factors is important for developing strategies to conserve the swift fox (Vulpes velox), a species being considered for listing under the Endangered Species Act, but available information about swift fox mortality is inadequate. We used radiotelemetry techniques to examine the magnitude and causes of mortality of swift fox populations in 2 study areas in western...
