Decline and disappearance of the Dusky Seaside Sparrow from Merritt Island, Florida Decline and disappearance of the Dusky Seaside Sparrow from Merritt Island, Florida
The Dusky Seaside Sparrow, Ammospiza maritima nigrescens, was first discovered by Charles J. Maynard near Salt Lake on the St. Johns River west of Titusville, Brevard County, Florida, on March 17, 1872.

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...

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...

Consistency in habitat preference of forest bird species Consistency in habitat preference of forest bird species
The important management conclusion that follows from our results is that the habitat requirements of most forest bird species, although quite specific for each species, apply generally throughout their breeding ranges. Thus a habitat management program that proves beneficial in one part of the breeding range of a species has a high likelihood of success in an area hundreds of kilometers...
