Influence of protein level and supplemental methionine in practical rations for young endangered masked bobwhite quail Influence of protein level and supplemental methionine in practical rations for young endangered masked bobwhite quail
A study was conducted to examine the protein requirement of young endangered masked Bobwhite quail (Colinus virginianus ridgwayi). Five practical starting rations containing 24 to 32% protein were fed alone and supplemented with methionine for 5 weeks. Supplemental methionine significantly improved growth of quail fed diets containing 24 and 26% protein. Increasing the protein level...

The peregrine falcon in Arizona: Habitat utilization and management recommendations The peregrine falcon in Arizona: Habitat utilization and management recommendations
The peregrine falcon once bred in significant numbers in Arizona. Good documentation is available for specific breeding sites and an additional 20 general locations. This report, based on the published literature, an extensive personal contact survey, an aerial habitat inventory (over 124 hours air time), and ground visits to over 300 locations, provides information on habitat...

Enzyme activities in plasma, liver, and kidney of black ducks and mallards Enzyme activities in plasma, liver, and kidney of black ducks and mallards
Activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatine phosphokinase (CPK), alkaline phosphatase (ALP), and lactate dehydrogenase (LDH) were measured in plasma, liver, and kidney, and gamma-glutamyl transferase (GGT) was measured in liver and kidney of black ducks (Anas rubripes). Activities of ALT, AST, GGT, and ornithine carbamyl transferase (OCT) were...

Hormonal treatment and flight feather molt in immature Sandhill Cranes Hormonal treatment and flight feather molt in immature Sandhill Cranes
Molt, the production of a new generation of feathers, is a poorly understood physiological phenomenon in nondomestic birds. Often in large birds like geese, flight is restricted by clipping the primary remiges on 1 wing and flight is restored after the molt when the primaries are replaced. A similar technique would be desirable for use with cranes conditioned for release to the native...

Diazinon residues in insects from sprayed tobacco Diazinon residues in insects from sprayed tobacco
Pooled samples of tobacco hornworms collected from a field sprayed with 0.84 kg/ha of diazinon were analyzed for residues at various intervals after application. No residues of the toxic metabolite diazoxon were detected (sensitivity 0.5 ppm) in any sample. Only one sample exceeded 1.0 ppm of the parent compound and was collected 4 hours after spraying. Residues declined over time (P

Small mammal-heavy metal concentrations from mined and control sites Small mammal-heavy metal concentrations from mined and control sites
Total body concentrations of zinc, copper, cadmium, lead, nickel, mercury and arsenic were determined for Peromyscus maniculatus and Microtus pennsylvanicus from an active zinc-copper mine near Timmins, Ontario, Canada, and a proposed zinc-copper mine near Crandon, Wisconsin, USA. Metal concentrations were evaluated with respect to area, species, sex and age groups. Metal concentrations...
