The decline of amphibians in California's Great Central Valley The decline of amphibians in California's Great Central Valley
Declines in amphibian populations are rarely reported on the community or ecosystem level. We combined broad-scale field sampling with historical analyses of museum records to quantify amphibian declines in California’s Great Central Valley. Overall, amphibians showed an unambiguous pattern of decline, although the intensity of decline varied both geographically and taxonomically. The...

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...

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...

A new assay for quantifying brown algal phlorotannins and comparisons to previous methods A new assay for quantifying brown algal phlorotannins and comparisons to previous methods
Quantitative measurement of phlorotannins (polyphenolics) in brown algae (Phaeophyta) by colorimetric assays can be confounded because: (1) most such assays also react to nonphlorotannin substances (interferences) and (2) the appropriate reference compound for such assays is not always clear, although phloroglucinol is typically used. We developed a new assay in which 2,4...
