Abstract

Anthropogenic forces have occurred throughout the duration of human occupation of our river systems. Their effects currently are ongoing and observable within river systems today. We tested for differences in the size distributions of fishes from archeological and ecological sites in the Lower Illinois River Valley (LIRV). There is a temporally related change in fish sizes between the two genera we tested, catfishes (Ictalurus spp.) and buffalo fishes (Ictiobus spp.), which may be attributed to anthropogenic influences, although other factors also impact observed temporal trends.
