Measuring and monitoring biological diversity: Standard methods for mammals Measuring and monitoring biological diversity: Standard methods for mammals
Measuring and Monitoring Biological Diversity: Standard Methods for Mammals provides a comprehensive manual for designing and implementing inventories of mammalian biodiversity anywhere in the world and for any group, from rodents to open-country grazers. The book emphasizes formal estimation approaches, which supply data that can be compared across habitats and over time. Beginning with...

Diagnostic criteria for selenium toxicosis in aquatic birds: dietary exposure, tissue concentrations, and macroscopic effects Diagnostic criteria for selenium toxicosis in aquatic birds: dietary exposure, tissue concentrations, and macroscopic effects
A feeding study with mallard ducks (Anas platyrhynchos) was conducted during March to July 1988 in Laurel, Maryland (USA), to identify diagnostic criteria for selenium toxicosis in birds. One-year-old male mallards in groups of 21 were fed diets containing 0, 10, 20, 40, or 80 parts per million (ppm) selenium, as seleno-DL-methionine, for 16 weeks. All ducks receiving 80 ppm died. Ducks...

Patch occupancy and dispersal of spruce grouse on the edge of its range in Maine Patch occupancy and dispersal of spruce grouse on the edge of its range in Maine
We surveyed 18 habitat patches (black spruce (Picea marinana) - tamarack (Larix larcina) wetlands) for spruce grouse (Dendragapus canadensis canadensis) on Mount Desert Island, Maine, during April-May in 1992 and 1993 to determine patch occupancy relative to patch area. We also equipped nine juvenile grouse with radio transmitters to determine movement and habitat use outside of patches...

Prevalence and histopathology of shell disease in turtles from Lake Blackshear, Georgia Prevalence and histopathology of shell disease in turtles from Lake Blackshear, Georgia
Turtles in Lake Blackshear, Crisp County, Georgia (USA) were evaluated for shell disease during intensive trapping efforts on 8 and 9 May 1990. The disease was most prevalent in Pseudemys concinna (74%) and Trachemys scripta (35%). The degree of necrosis on the carapace was significantly positively correlated with the degree of necrosis on the plastron in T. scripta (rs = 0.50), but not...

A resource conservative procedure for comparison of dose-response relationships A resource conservative procedure for comparison of dose-response relationships
The evaluation of effects of toxicants on a wildlife community can be complicated by varying responses among the community's constituent populations. Even within populations, considerable variability in dose-response relations may result from different avenues of exposure to the toxicant. Full-scale investigations of the dose-response relations among a variety of species and avenues of...
