Transportation impacts to wildlife on state route 37 in northern San Pablo Bay, California Transportation impacts to wildlife on state route 37 in northern San Pablo Bay, California
State Route 37 bisects conservation lands managed by San Pablo Bay National Wildlife Refuge (U.S. Fish & Wildlife Service) and Napa-Sonoma Marshes Wildlife Area (California Department of Fish and Game) in Solano and Sonoma Counties. The 2-lane highway connects Interstates 101 and 80 in northern San Francisco Bay and experiences ~26,000 vehicles per day. Road-killed wildlife between Napa...

The use of geographic information for fire management planning in Yosemite National Park The use of geographic information for fire management planning in Yosemite National Park
Fire has played a critical role in the ecosystems of Yosemite National park for millennia. Before the advent of Euro-Americans, lightning fires and fires set by Native Americans burned freely across the landscape. These fires burned periodically, with the interval between fires dependent on the availability of ignition sources, adequate fuels, and weather conducive to burning. As a...

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...

Parasites and marine invasions Parasites and marine invasions
Introduced marine species are a major environmental and economic problem. The rate of these biological invasions has substantially increased in recent years due to the globalization of the world's economies. The damage caused by invasive species is often a result of the higher densities and larger sizes they attain compared to where they are native. A prominent hypothesis explaining the...

Relating body condition to inorganic contaminant concentrations of diving ducks wintering in coastal California Relating body condition to inorganic contaminant concentrations of diving ducks wintering in coastal California
One egg from each of 114 red-breasted merganser (Mergus serrator) nests in 1977 and 92 nests in 1978 was collected and later analyzed for organochlorines, polybrominated biphenyls (PBBs), polychlorinated styrenes (PCSs). and metals. One egg was also collected from each of the dabbling duck nests located: Twenty-nine of these eggs were analyzed for organochlorines and metals in 1977; 10...

Estimates of carrying capacity for sea otters in Washington state Estimates of carrying capacity for sea otters in Washington state
Analyses of eggs of three species of North American accipitrine hawks for organochlorines and heavy metals indicate that contamination with DDE may be the primary cause of recent population declines of two of the species, Cooper's hawk and sharp-shinned hawk.

Trophic strategies, animal diversity and body size Trophic strategies, animal diversity and body size
A primary difference between predators and parasites is the number of victims that an individual attacks throughout a life-history stage. A key division within natural enemies is whether a successful attack eliminates the fitness of the prey or the host. A third distinctive axis for parasites is whether the host must die to further parasite development. The presence or absence of...

Good medicine for conservation biology: The intersection of epidemiology and conservation theory Good medicine for conservation biology: The intersection of epidemiology and conservation theory
A survey of organochlorine residues in woodcock wings was undertaken to determine whether these wings are suitable for showing regional differences in residues and to obtain a baseline in 1970-71 for later comparisons. Woodcock wings were obtained from the annual hunter's wing survey. Samples came from eight States (Louisiana, Maine, Michigan, New Hampshire, New Jersey, New York...
