Species traits as predictors for intrinsic sensitivity of aquatic invertebrates to the insecticide chlorpyrifos
Ecological risk assessment (ERA) has followed a taxonomy-based approach, making the assumption that related species will show similar sensitivity to toxicants, and using safety factors or species sensitivity distributions to extrapolate from tested to untested species. In ecology it has become apparent that taxonomic approaches may have limitations for the description and understanding of speci...
متن کاملRisks to aquatic organisms from use of chlorpyrifos in the United States.
The risk of chlorpyrifos (CPY) to aquatic organisms in surface water of North America was assessed using measured concentrations in surface waters and modeling of exposures to provide daily concentrations that better characterize peak exposures.Ecological effects were compared with results of standard laboratory toxicity tests with single species as well as microcosm and mesocosm studies compri...
متن کاملExposures of aquatic organisms to the organophosphorus insecticide, chlorpyrifos resulting from use in the United States.
Concentrations of CPY in surface waters are an integral determinant of risk to aquatic organisms. CPY has been measured in surface waters of the U.S. in several environmental monitoring programs and these data were evaluated to characterize concentrations, in relation to major areas of use and changes to the label since 2001, particularly the removal of domestic uses. Frequencies of detection a...
متن کاملSample Size Choice for Microarray Experiments
We review Bayesian sample size arguments for microarray experiments, focusing on a decision theoretic approach. We start by introducing a choice based on minimizing expected loss as theoretical ideal. Practical limitations of this approach quickly lead us to consider a compromise solution that combines this idealized solution with a sensitivity argument. The finally proposed approach relies on ...
متن کاملEffects of sample size on accuracy of species distribution models
Given increasing access to large amounts of biodiversity information, a powerful capability is that of modeling ecological niches and predicting geographic distributions. Because, sampling species’ distributions is costly, we explored sample size needs for accurate modeling for three predictive modeling methods via re-sampling of data for well-sampled species, and developed curves of model impr...
