Effects of winter undernutrition on body composition and physiological profiles of white-tailed deer Effects of winter undernutrition on body composition and physiological profiles of white-tailed deer
We examined the effects of undernutrition and recovery on body composition and blood and urinary profiles of 6 captive white-tailed deer (Odocoileus virginianus) between 18 December 1984 and 3 May 1985. Deer were weighed, and blood and urine were collected every 2 weeks from 10 January to 3 May. At Weeks 2, 8, and 14, body composition was estimated by the dilution of tritiated water...

Survival and band recovery rates of mallards in New Zealand Survival and band recovery rates of mallards in New Zealand
Mallards (Anas platyrhynchos) were banded at 4 discrete study areas in New Zealand. We used hunting season recoveries in conjunction with band recovery models to estimate annual survival and recovery rates and to test hypotheses about sources of variation in these rates. Recovery rates varied among the 4 areas and from year to year within areas. Recovery rates were generally higher for...

Survival rates of birds of tropical and temperate forests: Will the dogma survive? Survival rates of birds of tropical and temperate forests: Will the dogma survive?
Survival rates of tropical forest birds are widely assumed to be high relative to the survival rates of temperate forest birds. Much life-history theory is based on this assumption despite the lack of empirical data to support it. We provide the first detailed comparison of survival rates of tropical and temperate forest birds based on extensive data bases and modern capture-recapture...

Recent trends in counts of migrant hawks from northeastern North America Recent trends in counts of migrant hawks from northeastern North America
Using simple regression, pooled-sites route-regression, and nonparametric rank-trend analyses, we evaluated trends in counts of hawks migrating past 6 eastern hawk lookouts from 1972 to 1987. The indexing variable was the total count for a season. Bald eagle (Haliaeetus leucocephalus), peregrine falcon (Falco peregrinus), merlin (F. columbarius), osprey (Pandion haliaetus), and Cooper's...

Habitat use by postfledging American black ducks in Maine and New Brunswick Habitat use by postfledging American black ducks in Maine and New Brunswick
We examined habitat use by 112 postfledging American black ducks (Anas rubripes) in eastern Maine and southwestern New Brunswick from September through early December of 1985, 1986, and 1987. Ducks were captured on Moosehorn National Wildlife Refuge (NWR), Maine. Palustrine Emergent Wetland was the most preferred habitat type. Riverine habitats were avoided in September, but were used...

Selenium accumulation and elimination in mallards Selenium accumulation and elimination in mallards
Selenium accumulation and loss were measured in adult mallards (Anas platyrhynchos) fed selenomethionine during two experiments. In Experiment 1, both sexes were fed a diet containing 10 ppm selenium for 6 weeks, followed by 6 weeks on untreated feed. Selenium accumulation in liver and muscle of females was described by C=A(1−e−bt). Concentrations of selenium were predicted to reach 95%...

Field testing of commercially manufactured capture collars on white-tailed deer Field testing of commercially manufactured capture collars on white-tailed deer
We conducted 31 tests of commercially manufactured capture collars on female white-tailed deer (Odocoileus virginianus) in the Superior National Forest, Minnesota, under temperatures from -37C to 22C. Deer were recaptured in 28 of the 31 tests; in the 3 failures, we remotely released the collars from the deer. Communication with the collars was achieved from up to 3.0 km on the ground...
