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...

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...

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...
