John Wiens

John Wiens is an ecologist and evolutionary biologist known for his research on biodiversity and extinction rates. He is a professor at the University of Arizona, where he focuses on understanding the impacts of environmental change on species and their habitats. Recently, he co-authored a study published in PLOS Biology, which challenges the notion that we are currently experiencing a mass extinction, suggesting that while species extinctions are significant, extinctions at the genus level remain relatively low.
