Freshwater mussel conservation: A global horizon scan of emerging threats and opportunities

Global Change Biology, Volume 29, Issue 3, Page 575-589, February 2023., 2023
We identified 14 emerging and poorly understood threats and opportunities for addressing the global conservation of freshwater mussels over the next decade. Prioritization of our topics can help to drive a proactive approach to the conservation of this declining group which provides a multitude of important ecosystem services. Abstract We identified 14
