Channel response to sediment wave propagation and movement, Redwood Creek, California, USA Channel response to sediment wave propagation and movement, Redwood Creek, California, USA
Redwood Creek, north coastal California, USA, has experienced dramatic changes in channel configuration since the 1950s. A series of large floods (in 1955, 1964, 1972 and 1975) combined with the advent of widespread commercial timber harvest and road building resulted in extensive erosion in the basin and contributed high sediment loads to Redwood Creek. Since 1975, no peak flows have...

Mitochondrial-DNA variation among subspecies and populations of sea otters (Enhydra lutris) Mitochondrial-DNA variation among subspecies and populations of sea otters (Enhydra lutris)
We used restriction-enzyme analysis of polymerase-chain reaction-amplified, mitochondrial DNA (mtDNA) to assess genetic differentiation of subspecies and populations of sea otters, Enhydra lutris, throughout the range of the species. There were several haplotypes of mtDNA in each subspecies and geographically separate populations. MtDNA sequence divergence of haplotypes of sea otters was...

Altered behavior of parasitized killifish increases susceptibility to predation by bird final hosts Altered behavior of parasitized killifish increases susceptibility to predation by bird final hosts
Parasites that are transmitted from prey to predator are often associated with altered prey behavior. Although many concur that behavior modification is a parasite strategy that facilitates transmission by making parasitized prey easier for predators to capture, there is little evidence from field experiments. We observed that conspicuous behaviors exhibited by killfish (Fundulus...

Geographic variation in migratory behavior of greater white-fronted geese (Anser albifrons) Geographic variation in migratory behavior of greater white-fronted geese (Anser albifrons)
We studied the migration and winter distribution of adult Greater White-fronted Geese (Anser albifrons frontalis) radio-marked on the Yukon-Kuskokwim Delta (YKD) and Bristol Bay Lowlands (BBL) of Alaska from 1987 to 1992. The major autumn staging site for geese from both breeding areas was the Klamath Basin on the California/Oregon border. However, temporal use of this area differed...

Physical properties of woody fuel particles of Sierra Nevada conifers Physical properties of woody fuel particles of Sierra Nevada conifers
A study of the physical properties of Sierra Nevada conifer fuel particles showed that average diameter, squared quadratic mean diameter, surface-area-to-volume ratio, and specific gravity varied significantly by species for all four timelag fuel diameter size classes. The nonhorizontal angle was not significantly affected by size class, and the developmental stage of the overstory did...
