Organochlorine residues in bats after a forest spraying with DDT Organochlorine residues in bats after a forest spraying with DDT
Background levels of DDT and its metabolites (ZDDT) were extremely low or not detected in five species of forest-dwelling bats in northeastern Oregon, i.e., areas not sprayed with DDT in 1974. Other organochlorine pesticides were rarely found and no polychlotinated biphenyls (PCBs) were detected at any time during the study. Four of five species of bats showed significant changes in Z...

Population ecology of the mallard: VII. Distribution and derivation of the harvest Population ecology of the mallard: VII. Distribution and derivation of the harvest
This is the seventh in a series of comprehensive reports on population ecology of the mallard (Anas platyrhynchos) in North America. Banding records for 1961-1975 were used, together with information from previous reports in this series, to estimate annual and average preseason age and sex structure of the mallard population and patterns of harvest distribution and derivation. Age ratios...

Regional population inferences for the American woodcock Regional population inferences for the American woodcock
Woodcock (Philohela minor) bandings and recoveries from 1967 to 1977 were analyzed from two large banding reference areas corresponding to existing Eastern and Central harvest units. We examined temporal, age-specific, sex-specific, and geographic variation in both survival and recovery rates, using recently developed stochastic models. Survival rate estimates for females were higher...

Mourning Dove Nesting: Seasonal Patterns and Effects of September Hunting Mourning Dove Nesting: Seasonal Patterns and Effects of September Hunting
A nationwide State/Federal cooperative study was initiated in 1978 to examine effects of September hunting on mourning dove (Zenaida macroura) nesting. This study was designed to (1) determine the proportion of the annual total of dove nesting activity and production that occurs in September and October, and (2) determine if survival rates of mourning dove eggs and nestlings are lower in...

Influence of dietary protein and excess methionine on choline needs for young bobwhite quail Influence of dietary protein and excess methionine on choline needs for young bobwhite quail
Experiments were conducted with young Bobwhite quail (Colinus virginianus) to investigate the effect of differing dietary protein levels and nondetrimental amounts of excess methionine on choline needs. Growth and feed consumption of quail fed an adequate (27.3%) protein purified diet supplemented with 2000 mg/kg of choline were unaffected by increasing the level of excess methionine to...

Wolf depredation on livestock in Minnesota Wolf depredation on livestock in Minnesota
Depredation by wolves (Canis lupus) on cattle, sheep, and other livestock in Minnesota currently is a minor problem except to a few individual farmers. Indices to the seriousness of the problem are available only from recent years, so historical trends cannot be detected. From 1976 through 1980 the number of farms in the wolf range suffering verified losses to wolves ranged from 9 to 19...
