Age, sex, reproduction, and spatial organization of lynxes colonizing northeastern Minnesota Age, sex, reproduction, and spatial organization of lynxes colonizing northeastern Minnesota
From 1972 through 1978, lynxes (Felis lynx) emigrating from Canada were studied in northeastern Minnesota. Fourteen individuals were radio-tracked, 8 were ear-tagged, and 49 carcasses were examined. Sex ratios of the samples were equal during the first years of the study, but females predominated later. At least half of the radio-tagged lynxes were killed by humans; no natural mortality...

Inferences regarding survival and recovery rates of winter-banded canvasbacks Inferences regarding survival and recovery rates of winter-banded canvasbacks
Banding and recovery data from 3 populations of winter-banded canvasbacks (Aythya valisineria) were analyzed and survival and recovery rates were estimated. Sex-specific differences in these rates were detected in some populations, and lower survival rates were exhibited by females. Some geographic variation in survival rates was evident, suggesting that canvasbacks should not be managed...

DDT contamination at Wheeler National Wildlife Refuge DDT contamination at Wheeler National Wildlife Refuge
Disposal of industrial waste resulted in massive DDT contamination at Wheeler National Wildlife Refuge, Alabama. Nearly a decade after the cessation of DDT manufacturing at the facility responsible, concentrations of DDT residues in the local fauna are still high enough to suggest avian reproductive impairment and mortality. Populations of fish-eating birds are low, endangered species...
