Food habits and organochlorine contaminants in the diet of black skimmers, Galveston Bay, Texas, USA Food habits and organochlorine contaminants in the diet of black skimmers, Galveston Bay, Texas, USA
More than 500 food items of nestling Black Skimmers were identified representing 18 species of fish and 2 invertebrates. DDE and poly-chlorinated biphenyls (PCBs) were the only contaminants consistently detected in the black skimmer diet, carcass, and egg samples. Eggs contained 14 times the level of PCBs detected in the fish diet.

Sex and storage affect cholinesterase activity in blood plasma of Japanese quail Sex and storage affect cholinesterase activity in blood plasma of Japanese quail
Freezing at -25?C had confounding effects on cholinesterase (ChE) activity in blood plasma from breeding female quail, but did not affect ChE activity in plasma from males. Plasma ChE activity of control females increased consistently during 28 days of storage while both carbamate- and cidrotophos-inhibited ChE decreased. Refrigeration of plasma at 4?C for 2 days had little effect of ChE

Home range behavior among box turtles (Terrapene c. carolina) of a bottomland forest in Maryland Home range behavior among box turtles (Terrapene c. carolina) of a bottomland forest in Maryland
Eastern box turtles (Terrapene c. carolina) in a Maryland bottomland forest were studied over a period of years (1944-1981). Home ranges of 51 males averaged 146 + SD 48 m long and 105 + SD 38 m wide; ranges of 52 females averaged 144 + SD 52 m long and 100 + SD 38 m wide. An approximation of average home range size, based on an ellipse, is 1.20 ha for males and 1.13 ha for females...

Pentachlorophenol Hazards to Fish, Wildlife, and Invertebrates: A Synoptic Review Pentachlorophenol Hazards to Fish, Wildlife, and Invertebrates: A Synoptic Review
Pentachlorophenol (PCP) is now widely used as a wood preservative, and this has contributed to the detection of PCP residues in air, rain, groundwaters, surface waters, fish and aquatic invertebrates, and in human urine, blood, and milk of nursing mothers. This report briefly reviews the technical literature on ecological and toxicological aspects of PCP in the environment, with emphasis...

Responses to human intruders by birds nesting in colonies: Experimental results and management guidelines Responses to human intruders by birds nesting in colonies: Experimental results and management guidelines
Colonies of nesting wading birds and seabirds were studied at coastal sites in Virginia and North Carolina to determine distances at which birds flushed in response to human intrusion. There were few statistically significant relationships between flushing distances and colony size. Similarly, there were few differences between responses during incubation compared to post-hatching...

Contaminant residues in fish from Tensas River National Wildlife Refuge Contaminant residues in fish from Tensas River National Wildlife Refuge
Tensas River National Wildlife Refuge, Madison Parish, Louisiana, consists of bottomland hardwood swamps interspersed with small lakes and bayous supporting a diverse assemblage of waterfowl, fish, and assorted species of game and nongame wildlife. Fish collected in the refuge in 1984–85 from areas receiving direct inflow from agricultural runoff contained from 5 to 10 μg/g total DDT...

Population trends of North American shorebirds based on the International Shorebird Survey Population trends of North American shorebirds based on the International Shorebird Survey
Shorebirds Charadrii are prime candidates for population decline because of their dependence on wetlands that are being lost at a rapid pace. Thirty-six of the 49 species of shorebirds that breed in North America spend most of the year in Latin America. Because populations of most species breed and winter at remote sites, it may be most feasible to monitor their numbers at migration...
