Diagnostic brain residues of dieldrin: Some new insights Diagnostic brain residues of dieldrin: Some new insights
Forty adult male cowbirds were fed a diet containing 20 ppm dieldrin; 20 of the birds were randomly selected to die from dieldrin poisoning and 20 were sacrificed when dieldrin had made them too sick to eat. An average of 6.8 ppm dieldrin (range of 1.51 to 11.7) in the brain on a wet-weight basis was associated with a treatment-related cessation of feeding, whereas an average of 16.3 ppm...

Asiatic clam (Corbicula manilensis) and other foods used by waterfowl in the James River, Virginia Asiatic clam (Corbicula manilensis) and other foods used by waterfowl in the James River, Virginia
Corbicula manilensis was found in the gizzards of 24 ducks of 5 species taken from the James River, Virginia, between 1973 and 1976. Percent average volume in these species ranged from trace to 6%. This is the first known occurrence of this exotic clam in the food of duck in Chesapeake Bay. A total of 135 other food items was identified from the 116 gizzards of 9 species that were...

Plasma corticosterone and thyroxine concentrations during chronic ingestion of crude oil in mallard ducks (Anas platyrhynchos) Plasma corticosterone and thyroxine concentrations during chronic ingestion of crude oil in mallard ducks (Anas platyrhynchos)
1. Blood samples were collected from mallard ducks after 6, 12, and 18 weeks of dietary exposure to mash containing 0.015%, 0.150%, and 1.500% crude oil. 2. Plasma corticosterone concentrations in ducks fed mash containing 0.150% or 1.500% Alaskan Prudhoe Bay crude oil were uniformly depressed when compared to values in untreated control birds. 3. Plasma thyroxine concentration was not...

Effects of lead shot ingestion on delta-aminolevulinic acid dehydratase activity, hemoglobin concentration, and serum chemistry in bald eagles Effects of lead shot ingestion on delta-aminolevulinic acid dehydratase activity, hemoglobin concentration, and serum chemistry in bald eagles
Lead shot ingestion by bald eagles (Haliaeetus leucocephalus) is considered to be widespread and has been implicated in the death of eagles in nature. It was recently demonstrated under experimental conditions that ingestion of as few as 10 lead shot resulted in death within 12 to 20 days. In the present study hematological responses to lead toxicity including red blood cell ALAD...

Coccidia of Aleutian Canada geese Coccidia of Aleutian Canada geese
Fecal samples from 122 captive and 130 free-ranging Aleutian Canada geese (Branta canadensis leucopareia) were examined for oocysts of coccidia. Free-ranging geese sampled on the spring staging ground near Crescent City, California were infected with Eimeria hermani, E. truncata, E. magnalabia, E. fulva, E. clarkei and Tyzzeria parvula. Except for E. clarkei, the same species of coccidia...

Acute toxicities of toxaphene and endrin to larvae of seven species of amphibians Acute toxicities of toxaphene and endrin to larvae of seven species of amphibians
Seven species of amphibian larvae were exposed to toxaphene and endrin in a continuous-flow dosing system to determine differences in sensitivity to the two compounds, EC50 and LC50 estimates varied from those for Rana sphenocephala by no more than one order of magnitude when calculated on the basis of intended concentrations. Removal of pesticides from water by the test animals was...
