}Pesticides are receiving increasing attention as potential causes of amphibian declines, acting singly or in combination with other stressors, but limited information is available on the accumulation of current-use pesticides in tissue. The authors examined potential exposure and accumulation of currently used pesticides in pond-breeding frogs (Pseudacris regilla) collected from 7 high elevations sites in northern California. All sites sampled are located downwind of California's highly…

A negative relationship between Bd zoospore abundance in water and neonicotinoid concentrations in surface water is observed, which can be important contributors to a more complete understanding of the complex and potentially synergistic relationships between disease and pesticides.

It is suggested that freshwater snails can serve as bioindicators of pesticide exposure based on their capacity to passively accumulate tissue residues, and derived toxicokinetic parameters in the context of an environmentally relevant pulsed exposure suggests that residues can be measured in snails long after water concentrations fall below detection limits.

Test the hypothesis that pesticide concentrations are negatively correlated with frog population status by measuring pesticide concentrations in multiple media twice at 28 sites at high elevation in the southern Sierra Nevada, and results do not support the pesticide-site occupancy hypothesis.

It is found that cholinesterase activity in tadpoles was depressed in mountainous areas east of the Central Valley compared with sites along the coast or north of the Valley, and evidence that pesticides are instrumental in declines of these species is provided.

The role and relative effect of fish and pesticides on the mountain yellow-legged frog (Rana muscosa) is examined using unusually detailed data sets for a large portion of R.muscosa's historic range in California's Sierra Nevada, and the results represent the strongest evidence to date that windborne pesticides are contributing to amphibian declines in pristine locations.

For the two pesticides applied abundantly in the San Joaquin Valley during the sampling period, endosulfan and propargite, temporal variation in concentrations corresponded strikingly with application rates in the Valley with lag times of 1-2 weeks, which suggests that a large fraction of these two pesticides reaching the lakes originated in localized upwind areas within the Valley.

Examining the impact of a globally common herbicide on the survival of tadpoles for 16 days with and without the chemical cues emitted by predatory newts suggests that synergistic interactions between predatory stress and pesticides may indeed be a generalizable phenomenon in amphibians that occurs with a wide variety of pesticides.
