Although dam removal is an increasingly common stream restoration tool, it may also represent a major disturbance to rivers that can have varied impacts on environmental conditions and aquatic biota. In a paper titled "Dam Removal Effects on Benthic Macroinvertebrate Dynamics: A New England Stream Case Study, five researchers from Wesleyan examined the effects of dam removal on the structure, function, and composition of benthic macroinvertebrate (BMI) communities in a temperate New England stream. The benthic—or "bottom-dwelling”—macroinvertebrates are small aquatic animals that are commonly used to study biological conditions of water bodies. The paper is published in the May 21…
