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 composition.
•[5:31] He reports the study findings regarding species richness and community composition in redlined and greenlined neighborhoods.
•[6:55] Estien talks about the lasting legacy of racial injustice on the ecology of cities.
•[7:52] He explains why equitable access to biodiversity matters.
•[9:04] Caveats and limitations of the study.
•[10:09] Conclusion.

Tune into PNAS Science Sessions for a direct line to the people shaping modern science. Produced by PNAS, this podcast offers more than just summaries of published research; it’s where you hear the candid, often personal stories behind the headlines. Each episode features concise conversations with the researchers themselves-from emerging voices to established Academy members-alongside the policymakers whose decisions are informed by this work. You’ll get a genuine sense of the questions that drive these experts, the unexpected hurdles they face in their labs and field studies, and why their findings matter right now. The scope is deliberately wide, reflecting the interdisciplinary nature of science itself, covering discoveries that range from microscopic processes to planetary-scale phenomena. This isn't about dry lectures, but about capturing the human endeavor of investigation. For anyone curious about how science actually unfolds and wants to understand the context of breakthroughs as they happen, this podcast serves as an essential, engaging resource. It connects the dots between a published paper in a prestigious journal and the real-world implications that ripple out from it.
