Effects of white phosphorus on mallard reproduction Effects of white phosphorus on mallard reproduction

Extensive waterfowl mortality involving thousands of ducks, geese, and swans has occurred annually at Eagle River Flats, Alaska since at least 1982. The primary agent for this mortality has been identified as white phosphorus. Although acute and subacute lethality have been described, sublethal effects are less well known. This study reports on the effects of white phosphorus on...

Lead poisoning of passerines at a trap and skeet range Lead poisoning of passerines at a trap and skeet range

Our objective was to determine if ground foraging passerines in a woodland surrounding a trap and skeet range were subject to lead poisoning. Lead availability to birds was determined by shot counts and soil and earthworm analysis. Avian exposure to lead was identified by measuring free-erythrocyte protoporphyrin levels in blood and lead in tissues of three passerine species. Results...

The role of population monitoring in the management of North American waterfowl The role of population monitoring in the management of North American waterfowl

Despite the effort and expense devoted to large-scale monitoring programs, few existing programs have been designed with specific objectives in mind and few permit strong inferences about the dynamics of monitored systems. The waterfowl population monitoring programs of the U.S. Fish and Wildlife Service, Canadian Wildlife Service and state and provincial agencies provide a nice example...

Camping impact management at Isle Royale National Park: an evaluation of visitor activity containment policies from the perspective of social conditions Camping impact management at Isle Royale National Park: an evaluation of visitor activity containment policies from the perspective of social conditions

A survey of backcountry and wilderness campsites at Isle Royale National Park reveals that the park?s policies for managing visitor impacts have been remarkably effective in limiting the areal extent of camping-related disturbance. However, the dense spatial arrangement of designated campsites within backcountry campgrounds has also contributed to problems with visitor crowding and...

Epilogue: Lessons yet to be learned Epilogue: Lessons yet to be learned

This chapter provides a summary of the book Ecotoxicology of Amphibians and Reptiles edited by Sparling, Linder and Bishop. In addition to the comparative lack of information on effects and residue burdens of known contaminants in amphibians and reptiles, there is a plethora of new chemicals being produced and released into the environment on which no data exist at all. According to the

Early avian research at the Savannah River Site, South Carolina: historical highlights and possibilities for the future Early avian research at the Savannah River Site, South Carolina: historical highlights and possibilities for the future

Avian biology and collection of baseline population data was a major part of the first decade (1951-1961) of field research at the Savannah River Site (SRS). Baseline inventories involving organisms and land-use types were part of the mission in the early contracts between the Atomic Energy Commission (now the Department of Energy) and the University of Georgia prior to the establishment...
