In this study, two ways of accumulating Pb were investigated: natural accumulation and chemically enhanced accumulation with the chelating agent ethylenediaminetetraacetic acid (EDTA). Young cattails (Typha latifolia) were removed from the Arcata Comm . . .

Improved understanding of the importance of estuarine wetlands to the function of coastal ecosystems has lead to increased restoration efforts of degraded wetlands. The South Slough National Estuarine Research Reserve (SSNERR) in Coos Bay, Oregon, has . . .

Five species of western gooseberries (Ribes: Grossulariaceae) hybridize to varying degrees in northwestern California and southwestern Oregon. Pollinator surveys and hand-pollination experiments were conducted to identify reproductive barriers between . . .

Throughout their global distribution, bats vary in their use of microhabitats along the vertical strata of forests. Ground-based detection techniques typically cannot sample canopy strata in taller forests as it falls beyond detection and netting rang . . .

The movement ecology of the adult northern red-legged frog (Rana aurora aurora) is essentially unknown throughout its range. Systematic studies, particularly those that investigate terrestrial movements of these animals, are urgently needed since this . . .

Long term comparisons are important for understanding intertidal community dynamics and documenting response to environmental pressures. This study compares the historical abundance of high intertidal sessile organisms at two rocky intertidal sites wi . . .

Historically human olfaction has been underestimated. There is considerable recent evidence that olfaction is biologically important in social and emotional contexts, including mate selection and kin recognition. Observations of humans in social conte . . .

I investigated seasonal activity, movement patterns, and habitat use of the wandering salamander, Aneides vagrans, in an old-growth forest canopy. During the fall and winter months from September 2000 to January 2003, a mark—recapture study of salaman . . .

The Early Devonian epoch (419.2 ±3.2-393.3 ±1.2 Ma) (Gradstein 2012) marked the commencement of a rapid evolutionary radiation and increase in the diversity and complexity of basal tracheophytes and other groups of land plants. While the importance of . . .
