Of mice and mallards: Positive indirect effects of coexisting prey on waterfowl nest success Of mice and mallards: Positive indirect effects of coexisting prey on waterfowl nest success
Coexisting prey species interact indirectly via their shared predators when one prey type influences predation rates of the second prey type. In a temperate system where the predominant shared predator is a generalist, I studied the indirect effects of rodent populations on waterfowl nest success, both within the nesting season among sites and among years. Among six to ten upland fields...

September-March survival of female northern pintails radiotagged in San Joaquin Valley, California September-March survival of female northern pintails radiotagged in San Joaquin Valley, California
To improve understanding of pintail ecology, we radiotagged 191 hatch-year (HY) and 228 after-hatch-year (AHY) female northern pintails (Anas acuta) in the San Joaquin Valley (SJV), and studied their survival throughout central California, USA, during September-March, 1991-1994. We used adjusted Akaike Information Criterion (AICc) values to contrast known-fate models and examine...

Habitat use and foraging behavior of Townsend's big-eared bat (Corynorhinus townsendii) in coastal California Habitat use and foraging behavior of Townsend's big-eared bat (Corynorhinus townsendii) in coastal California
Radiotracking studies of Townsend's big-eared bat (Corynorhinus townsendii) were conducted in grazed grassland and coastal forest (California bay, Douglas-fir, and redwood) at Point Reyes National Seashore in coastal central California. Radiotagged bats were used to determine the foraging patterns of both female and male bats and to locate alternate roost sites. The animals showed...

Use of acoustic classification of sidescan sonar data for mapping benthic habitat in the Northern Channel Islands, California Use of acoustic classification of sidescan sonar data for mapping benthic habitat in the Northern Channel Islands, California
Highly reflective seafloor features imaged by sidescan sonar in nearshore waters off the Northern Channel Islands (California, USA) have been observed in subsequent submersible dives to be areas of thin sand covering bedrock. Adjacent areas of rocky seafloor, suitable as habitat for endangered species of abalone and rockfish, and encrusting organisms, cannot be differentiated from the...
