1987, Book chapter, Seabirds: feeding ecology and role in marine ecosystems
Distribution and effects of acidic deposition on wildlife and ecosystems
K. L. Stromborg, J. R. Longcore
Peter Kaemar, J. Legath, editor(s)
1987, Book chapter, Collected Reports from the Czechoslovak-American Symposium on Toxic Effects of Chemical Environmental Contaminants upon Production and Reproduction Ability in Free-Living Animals (held October 3-4, 1983).
Acidic deposition occurs over most of the United States and the deposition patterns and theoretical vulnerabilities of aquatic ecosystems to chemical changes can be delineated, but few data exist on concomitant biological effects. Hypothetical direct effects are limited primarily to toxicity of various heavy metals mobilized at reduced...
Genetic management of endangered species at the Patuxent Wildlife Research Center

1987, Book chapter, Waterfowl and Wetlands Symposium: Proceedings of a Symposium on Waterfowl and Wetlands Management in the Coastal Zone of the Atlantic Flyway
Using previously published atlas data for 122 mixed-species wading bird colonies on islands along the Atlantic coast (Maine to Florida, 1976-77), we examined relationships between population sizes of 11 species of egrets, herons, ibises, and wood storks (Mycteria americana) and nine habitat variables. On nautical charts, we measured four island...

Field methods to evaluate effects of pesticides on wildlife of the northwestern United States
Charles J. Henny
1987, Book chapter, Collected Reports from the Czechoslovak-American Symposium on Toxic Effects of Chemical Environmental Contaminants upon Production and Reproduction Ability in Free-Living Animals (held October 3-4, 1983)
Field .methods used to evaluate the impact of organochlorine and organophosphate pesticides on wildlife populations in the Pacific Northwest are reviewed. Five field studies, presented in a CASE HISTORY format, illustrate study designs .and thetypes of information collected. The pesticides investigated included DDT, heptachlor, endr1n, and famphur, and the species...
