Distribution and ecology of the big-eared bat, Corynorhinus (=Plecotus) townsendii in Californa Distribution and ecology of the big-eared bat, Corynorhinus (=Plecotus) townsendii in Californa
This study had two primary objectives: to conduct roost surveys C. townsendii in two parts of California where distributional information was most limited or lacking, and to obtain information on roosting and foraging ecology in two distinctly different habitats. This project was urgently needed because 1) recent California Department of Fish and Game surveys (conducted in 1987-1991)...

Fuel bed characteristics of Sierra Nevada conifers Fuel bed characteristics of Sierra Nevada conifers
A study of fuels in Sierra Nevada conifer forests showed that fuel bed depth and fuel bed weight significantly varied by tree species and developmental stage of the overstory. Specific values for depth and weight of woody, litter, and duff fuels are reported There was a significant positive relationship between fuel bed depth and weight. Estimates of woody fuel weight using the planar...

The role of natural history collections in documenting species declines The role of natural history collections in documenting species declines
Efforts to document the decline of extant populations require a historical record of previous occurrences. Natural history museums contain such information for most regions of the world, at least at a coarse spatial scale. Museum collections have been successfully used to analyse declines in a wide range of plants and animals, at spatial scales ranging from single localities to large...

Genetic differentiation between wintering populations of lesser snow geese nesting on Wrangel Island, Russia Genetic differentiation between wintering populations of lesser snow geese nesting on Wrangel Island, Russia
Arctic breeding populations of Lesser Snow Geese (Chen c. caerulescens) range from Baffin Island in eastern Canada to Wrangel Island, Russia, which is located 650 km west of Alaska (Bellrose 1980). Although hundreds of thousands of Lesser Snow Geese may have occupied the Russian arctic in the mid1800s (see Takekawa et al., 1994), the Wrangel Island birds constitute the only remnant...

Contaminants in wintering canvasbacks and scaups from San Francisco Bay, California Contaminants in wintering canvasbacks and scaups from San Francisco Bay, California
Organochlorines, metals, and trace elements were measured in liver, kidney, or whole-body tissues of canvasbacks (Aythya valisineria), lesser scaups (A. affinis), and greater scaups (A. marila) collected from San Francisco Bay and three coastal areas of California during the winter of 1986–1987. Potentially toxic concentrations of mercury (mean ≤10.4 µg/g, dry weight) and selenium (mean...
