Between-habitat movement of dusky-footed woodrats and vulnerability to predation
Article Abstract:
Management of northern spotted owls in northwestern California is helped by knowledge of their main pre species, the dusky-footed woodrat. A study tracked the woodrats using radio-telemetry, to investigate the low abundance of woodrats in old growth forests, in relation to their dominance in the diet of the northern spotted owls. There were no significant differences in home range size detected, and none of the woodrats emigrated permanently. The study found that woodrats would make short forays into older aged forests during the night, making them less accessible to avian predators.

Response of nesting ducks to habitat and management on the Monte Vista National Wildlife Refuge, Colorado
Article Abstract:
The effect of habitat and management on nest density and success was examined through duck nesting data provided by the Monte Vista National Wildlife Refuge in Colorado. 4,154 duck nests were discovered on 16,159 kms. of transect from 1964-1990 (except 1977). Mallards, at 54.5% of the duck nests, was the most abundant, with teal species and northern pintails coming close. Over the 26-year period, 52.4% of 4,154 nests were successful. Nest failure usually results from predation, desertion, flooding, and other unknown causes.
