Pnas Science Sessions

How redlining affects biodiversity Science Sessions are brief conversations with cutting-edge researchers, National Academy members, and policymakers as they discuss topics relevant to today's scientific community. Learn the behind-the-scenes story of work published in the Proceedings of the National Academy of Sciences (PNAS), plus a broad range of scientific news about discoveries that affect the world around us. In this episode, Cesar Estien explores the legacy of mid-20th century redlining through the biodiversity of disadvantaged neighborhoods. In this episode, we cover: •[00:00] Introduction •[1:04] Cesar Estien, an urban ecologist at the University of Washington, describes the practice of redlining. •[2:50] He tells how a study of redlining and environmental quality led to a study of animal diversity. •[3:33] Estien describes why the study cities of San Francisco, Oakland, Los Angeles, and San Diego were chosen for the study. •[4:25] He explains the difference between species richness and community com
