Avian species differences in the intestinal absorption of xenobiotics (PCB, dieldrin, Hg2+) Avian species differences in the intestinal absorption of xenobiotics (PCB, dieldrin, Hg2+)
1. Intestinal absorption of a polychlorinated biphenyl, dieldrin, and mercury (from HgCl2) was measured in adult Northern bobwhites, Eastern screech owls, American kestrels, black-crowned night-herons and mallards in vivo by an in situ luminal perfusion technique. 2. Bobwhites, screech owls and kestrels absorbed much more of each xenobiotic than black-crowned night-herons and mallards. 3...

Management to conserve forest ecosystems Management to conserve forest ecosystems
Historically, management of forests for wildlife has emphasized creation of openings and provision for a maximum of edge habitats. Wildlife managers have believed, quite logically, that increased sunlight enhances productivity among plants and insects, resulting in greater use by game animals and other wildlife. Recent studies comparing breeding bird populations of extensive forests with...

Contaminants in wood stork eggs and their effects on reproduction, Florida, 1982 Contaminants in wood stork eggs and their effects on reproduction, Florida, 1982
One egg was removed from five Wood Stork (Mycteria americana) nests at each of eight colonies in central and northern Florida in 1982. DDE and mercury were present in all eggs with concentrations ranging up to 9.4 and 0.73 ppm wet weight, respectively. PCBs occurred in 25 eggs with a high value of 3.5 ppm. No other organochlorine compounds occurred in more than 307. of the eggs...

DDE in birds' eggs: Comparisons of two methods for estimating critical levels DDE in birds' eggs: Comparisons of two methods for estimating critical levels
The sample egg technique and eggshell thickness-residue regression analysis were comparatively evaluated as tools in estimating critical levels of DDE in birds? eggs that seriously affect reproductive successa nd population starts....In comparing critical values of DDE that were derived from the two methods, the estimates were lower using the sample egg technique for both the Brown...

Avian endocrine responses to environmental pollutants Avian endocrine responses to environmental pollutants
Many environmental contaminants are hazardous to populations of wild birds. Chlorinated hydrocarbon pesticides and industrial pollutants are thought to be responsible for population declines of several species of predatory birds through eggshell thinning. Studies have demonstrated that these contaminants have estrogenic potency and may affect the functioning of the gonadal and thyroidal...
