Organochlorine residues and autopsy data from bald eagles 1966-68
Sixty-nine bald eagles found moribund or dead in 25 States during 1966-68 were analyzed for pesticide residues. Residues of polychlorinated biphenyls and DDE were detected in all samples of eagle carcasses; residues of dieldrin were detected in 68 and residues of DDD in 64; DDT, heptachlor epoxide, and DCBP were detected less frequently. Eight specimens had levels of dieldrin in the brain within t

Chemical and biological conditions in Bald Eagle Creek and prognosis of trophic characteristics of Foster Joseph Sayers Reservoir, Centre County, Pennsylvania
Foster Joseph Sayers. Reservoir will b.e impounded on moderately fertile soils; however, its water source, Bald Eagle Creek, is a bicarbonate-water stream that is over~y-enriched with nutrients. About 650 of the 1,730 acres to be inundated in summer are subject to infestation with aquatic weeds. Nuisance algal "blooms" are expected to occur in summer. The reservoir will stratify in early summer an

Propagation of captive American kestrels
A colony of kestrels (Palco sparverius) was established at the Patuxent Wildlife Research Center in 1964 in connection with work on pesticides. The kestrels were acquired from the wild, both as nestlings and as full-grown birds, and were housed in several rows of outdoor pens. Each 50 x 20 ft pen was covered with wire netting and had its long sides in common with adjacent pens. During the first

Interstitial water studies on small core samples, Deep Sea Drilling Project, Leg 1
The most dramatic variations in pore water composition occurred in Holes 2 and 3 in the Gulf of Mexico. Both holes showed a strong increase in salinity with depth, evidently owing to diffusion from underlying salt bodies. However, on Challenger Knoll (Hole 2) a sharp drop in salinity was observed in the cap rock of the salt dome in which chloride fell to only 4.8 percent. The drop is attributed to

Duck viral enteritis (duck plague) in North American Waterfowl
Duck Viral Enteritis (DVE) was first recognized in North America in January 1967, when an outbreak occurred in a commercial flock of white Pekin ducks in Suffolk County, Long Island, New York (Leibovitz and Hwang, 1968b). Originally described as a disease of domestic ducks in the Netherlands, DVE has since been reported from India and Belgium. it is also believed to have occurred in China and Fran
