Impacts of a Century‐Old Urban Dam on Water Quality and Habitat Composition, Flint River, Flint, MI
River Research and Applications, EarlyView.ABSTRACT Dams significantly influence river ecosystems worldwide, fragmenting habitats, altering sediment transport, and reducing biodiversity. Urban rivers are especially vulnerable, where dams compound stressors such as channelization, pollution, and degraded riparian zones. In response, dam removals are a growing restoration tool globally.

Wildlife Biology, EarlyView.Infectious diseases are commonly cited as significant contributors to wildlife population declines. It is, therefore, important to investigate the extent to which tools designed to mitigate the effects of infectious diseases explain wildlife responses to habitat management.
