Analysis of benthic macroinvertebrate samples from St. Marys River sediment cores 1987

In January, 1990, Tarandus Associates Limited was contracted by the Ontario Ministry of the Environment (MOE) to complete the identification, enumeration, and statistical analysis of benthic invertebrate samples collected at five stations in the St. Marys River in 1987. The objectives of the study were: 1) to identify, enumerate and tabulate benthic macroinvertebrates in sediment core samples from each station; and 2) to summarize and interpret the benthic data and examine relationships between the benthic community and various environmental factors.
