Relationships between nesting populations of wading birds and habitat features along the Atlantic Coast Relationships between nesting populations of wading birds and habitat features along the Atlantic Coast
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 characteristics (area, length, width, shape...

Field methods to evaluate effects of pesticides on wildlife of the northwestern United States Field methods to evaluate effects of pesticides on wildlife of the northwestern United States
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 studied included the...

Genetic management of endangered species at the Patuxent Wildlife Research Center Genetic management of endangered species at the Patuxent Wildlife Research Center
Summary: The Patuxent Wildlife Research Center conducts one of the world's largest and best-known research programs for captive propagation of endangered wildlife. In order to be effective and to ensure the long-term survival of species, researchers at Patuxent attempt to manage captive populations according to the principles of population genetics. This includes the use of estimated...

The use of kestrels in toxicology The use of kestrels in toxicology
Various species of kestrels have become important bioindicators of environmental quality and test species for comparative toxicology in captivity. At least 7 species of kestrels have been used to document the presence of environmental contamination primarily organochlorines and metals, in at least 15 countries. Captive kestrels have been used in studies involving a wide variety of...

Oral and intramuscular toxicity of inorganic and organic mercury chloride to growing quail Oral and intramuscular toxicity of inorganic and organic mercury chloride to growing quail
The lethal toxicity of inorganic (HgCl 2 ) and organic (CH 3 HgCl) mercury chloride was compared for Coturnix (Japanese quail, Coturnix japonica) of different ages from hatch through adulthood by single‐dose acute oral and intramuscular injections and by a 5‐d dietary trial. Sublethal mercury toxicity was studied by evaluation of plasma and brain cholinesterase activity. CH 3 HgCl was...
