520 |a"The Yamaska River watershed in Quebec, Canada, is intensely farmed and heavily polluted with poorly treated domestic and industrial wastes. In this study, the responses of several components of the benthic macroinvertebrate community to municipal/industrial versus agricultural pollution in the Yamaska River and its tributaries were investigated, and the performance of eight diversity and biotic indices for assessing these responses was evaluated"--Abstract.
