Wolf management in the 21st century: From public input to sterilization Wolf management in the 21st century: From public input to sterilization
Human-population increase and land development portend increasing conflict with large predators. Concurrently, changes and diversification of human attitudes are bringing increased disagreement about wildlife management. Animal-rights advocacy resulting from urbanization of human populations conflicts with traditional wildlife management. These forces focus more on wolves than on other...

Environmental contaminants and productivity in an extinct heronry at Charleston Harbor, South Carolina, U.S.A., 1984 Environmental contaminants and productivity in an extinct heronry at Charleston Harbor, South Carolina, U.S.A., 1984
Our objectives were to collect information on contaminant levels and productivity of wading birds at the Drum Island heronry in Charleston Harbor, South Carolina, before diversion of the Cooper River took place in 1985. The diversion was expected to reduce water flow by ∼80% into the Harbor, thereby concentrating industrial effluents near the heronry with potentially harmful effects...

Seed deterioration in flooded agricultural fields during winter Seed deterioration in flooded agricultural fields during winter
We determined rate of seed deterioration for 3 crops (corn, rice, and soybean) and 8 weeds commonly found in agricultural fields and moist-soil management units in the Mississippi Alluvial Valley (MAV). The weeds were broadleaf signalgrass (Brachiaria platyphylla), junglerice barnyardgrass (Echinochloa colonum), morningglory (Ipomoea sp.), panic grass (Panicum sp.), bull paspalum...

In memoriam: Harvey I. Fisher, 1916-1994 In memoriam: Harvey I. Fisher, 1916-1994
Harvey Irvin Fisher was born on 15 June 1916 in Edgar, Nebraska, and spent his youth near Blue Springs, Missouri. Following his A.A. from Kansas City in 1935, and B.S. from Kansas State University in 1937, he married Mildred Hoch; they had three sons. He received his Ph.D. from the University of California, Berkeley, in 1942. From 1942 through 1945, while at Berkeley, he was Technical...

Cytochrome P450 and contaminant concentrations in nestling black-crowned night-herons and their interrelation with sibling embryos Cytochrome P450 and contaminant concentrations in nestling black-crowned night-herons and their interrelation with sibling embryos
Hepatic cytochrome P450-associated monooxygenase activities were measured in 11-d-old nestling black-crowned night-herons (Nycticorax nycticorax) collected from a reference site (next to Chincoteague National Wildlife Refuge, VA, USA) and three contaminated sites (Cat Island, Green Bay, WI, USA; Bair Island, San Francisco Bay, CA, USA; and West Marin Island, San Francisco Bay, CA, USA)

Purification and immunochemical detection of β-naphthoflavone-and phenobarbital-induced avian cytochrome P450 enzymes Purification and immunochemical detection of β-naphthoflavone-and phenobarbital-induced avian cytochrome P450 enzymes
Livers from mallards (Anas platyrhynchos) were treated with either β-naphthoflavone (50 mg/kg) or phenobarbital (70 mg/kg). Purification of induced hepatic cytochrome P450 was accomplished using both DEAE and hydroxyapatite columns, as well as sodium dodecyl sulfate polyacrylamide gel electrophoresis separation. Polyclonal antibodies to these proteins were then produced in young male New...

Toxicity and oxidative stress of different forms of organic selenium and dietary protein in mallard ducklings Toxicity and oxidative stress of different forms of organic selenium and dietary protein in mallard ducklings
Concentrations of over 100 ppm (mg/kg) selenium (Se) have been found in aquatic plants and insects associated with irrigation drainwater and toxicity to fish and wildlife. Composition of diet for wild ducklings can vary in selenium-contaminated environments. Earlier studies have compared toxicities and oxidative stress of Se as selenite to those of seleno-DL-methionine (DL) in mallards...

Reproductive physiology Reproductive physiology
Conclusions: Although the general pattern of avian physiology applies to cranes, we have identified many physiological mechanisms (e.g., effects of disturbance) that need further study. Studies with cranes are expensive compared to those done with domestic fowl because of the crane's larger size, low reproductive rate, and delayed sexual maturity. To summarize, the crane reproductive...
