Wolf pack witness Wolf pack witness
Arctic wolves have almost never come in contact with humans because of their location in the extreme northern latitudes. Their lack of experience with human intruders makes them an easy species to study.

Malocclusion in the jaws of captive bred Arctic wolves Malocclusion in the jaws of captive bred Arctic wolves
Similar abnormalities in the skulls of captive Arctic Wolves (Canis lupus arctos) and a wild Arctic wolf found dead on Ellesmere Island, Canada, in 1986 are described. The malocclusion is likely to be recessively inherited and would be expressed more frequently in association with increased levels of inbreeding. A re-shaping of the skulls may have occurred due to the effects of the...

Diagnostic criteria for selenium toxicosis in aquatic birds: dietary exposure, tissue concentrations, and macroscopic effects Diagnostic criteria for selenium toxicosis in aquatic birds: dietary exposure, tissue concentrations, and macroscopic effects
A feeding study with mallard ducks (Anas platyrhynchos) was conducted during March to July 1988 in Laurel, Maryland (USA), to identify diagnostic criteria for selenium toxicosis in birds. One-year-old male mallards in groups of 21 were fed diets containing 0, 10, 20, 40, or 80 parts per million (ppm) selenium, as seleno-DL-methionine, for 16 weeks. All ducks receiving 80 ppm died. Ducks...

Patch occupancy and dispersal of spruce grouse on the edge of its range in Maine Patch occupancy and dispersal of spruce grouse on the edge of its range in Maine
We surveyed 18 habitat patches (black spruce (Picea marinana) - tamarack (Larix larcina) wetlands) for spruce grouse (Dendragapus canadensis canadensis) on Mount Desert Island, Maine, during April-May in 1992 and 1993 to determine patch occupancy relative to patch area. We also equipped nine juvenile grouse with radio transmitters to determine movement and habitat use outside of patches...
