Description:

We will measure the correspondence of endpoints from chronic toxicity tests with the amphipod, Hyalella azteca, to a series of in situ macrobenthic community endpoints, starting with those endpoints most similar to those monitored in the laboratory test, then expanding to include community level endpoints that represent the most developed methods for characterizing ecological condition in streams.

Project Information:

Approach :An integrated study of Peak Creek, Pulaski, VA will include observations of impact in both field and laboratory with appropriate chemical and physical observations to link the two sets of observations. Samples will be collected from 8 stations varying in degree of metal contamination on 4 sampling dates. Both upstream depositional and downstream riffle habitats will be sampled. By comparing chronic toxicity test results to instream community response in both habitats, toxicity test results can be compared to the real-world data most closely related to the population tested in the laboratory but also to the real-world data that represents our best developed measures of ecological condition. The degree of correspondence between toxicity test results and field impact will be characterized using tabular decision matrices, correlation analyses, errors from predicting field impact based on multivariate concentration-response models derived from laboratory tests, and goodness-of-fit tests. Seasonal variation in correspondence will be assessed through partial regression coefficients.
