But for Sonja Christensen, an assistant professor in the Department of Fisheries and Wildlife in Michigan State University’s College of Agriculture and Natural Resources, the focus — now and all year long — is on protecting deer from disease.

Pollutants are important to biodiversity’s role in spread of wildlife diseases

Conventional wisdom among ecologists holds that the more species there are inhabiting an ecosystem, the less vulnerable any one species will be to a threat like a parasite. A new study of tadpoles at the University of Wisconsin–Madison illustrates how overlapping biological and environmental factors can complicate how we value protecting diverse animal communities. The researchers found that environmental pollutants like road salt influence whether increased biodiversity helps or hinders disease outbreaks in wildlife, which can complicate how we value protecting diverse animal communities.
