Effects of DDT on bobwhite quail adrenal gland Effects of DDT on bobwhite quail adrenal gland
A wide range of responses to sublethal levels of DDT exist, many of which are species specific and vary within each species depending upon age, sex, and physiological state. Sublethal levels of DDT do cause an increase in the adrenal cortical tissue of bobwhite quail, which may cause increased secretion of corticosteroids, and in turn affect reproduction. A delicate homeostatic balance...

Relations of the brown pelican to certain environmental pollutants Relations of the brown pelican to certain environmental pollutants
Nearly all brown pelican eggs collected from 13 colonies in South Carolina, Florida, and California in 1969 and from 17 colonies in South Carolina and Florida in 1970 exhibited eggshell thinning. Of the 100 eggs analyzed for residues of pollutants, all eggs contained measurable quantities of DDE; most eggs contained measurable quantities of p,p'-DDD, p,p'-DDT, dieldrin, or PCB's...

Breeding red-winged blackbirds in captivity Breeding red-winged blackbirds in captivity
Ability to establish and maintain self-sustaining breeding colonies of captive Red-winged Blackbirds (Agelaius phoeniceus) would facilitate long-term studies designed to develop methods for alleviating blackbird depredations as well as provide basic life history data. To be most useful, the colonies should be established in pens near laboratory facilities; this frequently involves...

Taxonomic status of certain clapper rails of southwestern United States and northwestern Mexico Taxonomic status of certain clapper rails of southwestern United States and northwestern Mexico
Examination of 58 Clapper Rail specimens taken in the breeding season from the Colorado Valley and the west coast of mainland Mexico verifies the distinctness of the races Rallus longirostris yomanensis, R. 1. rhizophorae, and R. 1. nayaritensis. Rallus 1. yumanensis is a relatively pale brown, pointed-winged, summer resident of freshwater marshes along the valley and delta of the...

Relationships between chemical structure and rat repellency: II. compounds screened between 1950 and 1960 Relationships between chemical structure and rat repellency: II. compounds screened between 1950 and 1960
Over 4,600 compounds, chiefly organic types, were evaluated using both a food acceptance test (Part A) and a barrier penetration bioassay (Part B), to correlate relationships between chemical structure and rodent repellency. These chemicals are indexed and classified according to the functional groups present and to the degree of substitution within their molecular structures. The...
