Halogenated diphenyl ethers identified in avian tissues and eggs by GC/MS
Chlorinated and brominated diphenyl ether compounds (DPEs) have been detected by gas Chromatography/ mass spectrometry (GC/MS) in eggs and carcasses of fish-eating birds from Louisiana, Michigan, Ohio, Rhode Island, Texas, Virginia, and Ontario, Canada. Three of these compounds were quantified; the highest concentration of 0.90 ppm tetrachloro DPE was found in a common tern carcass (Sterna hirund

Chewing-removal of radio collars by wolves in Wisconsin
From May 1980 through august 1981 we placed 11 machine-belt radio collars on 10 adult gray wolves (Canis lupus) from 4 packs in northwestern Wisconsin. This note reports the loss of 7 collars from chewing by other wolves, apparently pack-mates.

Factors affecting the distribution of mallards wintering in the Mississippi alluvial valley
The Mississippi Alluvial Valley (MAV) is the principal wintering area for Mallards (Anas platyrhynchos) in the Mississippi Flyway. Here, we consider it a distinct habitat (sensu Fretwell 1972), i.e. fitness is relatively homogeneous among ducks within the MAV but different from that of ducks in other such habitats. We analyzed recovery distributions of Mallards banded preseason (July-September 195

Impacts of forest herbicides on wildlife: Toxicity and habitat alteration
This paper begins with a review of both laboratory and field studies on tbe possible direct toxic effects of herbicides on terrestrial vertebrates, primarily birds and mammals. Alteration of the palatability of forage and changes in reproductive success are also discussed. Emphasis is placed on the use of herbicides in forestry; studies dealing with agricultural systems are referenced where appr
