The researchers find: “By modifying both habitat structure and prey abundance, beaver engineering affected bat activity, richness, and feeding activity directly and indirectly. The research was funded by the Blue-Green Biodiversity Research Initiative (through Swiss Federal Institutes of Technology Domain) and National Beaver Project. The authors confirmed their hypothesis, finding “that bat species richness, activity and feeding activity were significantly higher in beaver-engineered Pool compared to Control areas. Ultimately, the researchers find that bats and birds feeding on contaminated midges could result in low to moderate chronic pesticide exposure.
