In this episode, Bob helps us understand how conservation breeding works as a response to the amphibian extinction crisis, especially when chytrid fungus makes protecting wild populations impossible and “insurance populations" are needed to prevent species loss.

Drawing on Bob’s experience, the episode traces early work on the Puerto Rican toad (sapo concho), then goes on to unpack population management and conservation breeding.

Then, together with Amphibian Ark’s Executive Director, Jonathan Wilcken, we outline the way Amphibian Ark works today and how it is going from a reactive crisis-response organization to a more proactive organization that continues rescuing amphibians in crisis around the world.

In Episode 2 of Amphibian Rescue, we trace the rapid shift from alarm to action that led to Amphibian Ark. After the 2004 Global Amphibian Assessment confirmed amphibians as the most threatened vertebrates and chytrid fungus spread globally, a 2005 summit in Washington, DC helped shape the Amphibian Conservation Action Plan and sparked the idea of emergency “survival assurance colonies,” with the idea of an “Amphibian Ark” coined there.

In this episode, Dr. Bob Lacy and Dr. Onnie Byers describe how IUCN’s CBSG/CPSG, ASG, and WAZA mobilized quickly, raised early pledges, and began building amphibian husbandry and collaboration across zoos, field teams, veterinarians, and researchers—helping create a global ex situ safety net that would, in 2007, become Amphibian Ark.

In Episode 1 of Amphibian Rescue, we go back to the beginning. Herpetologist Dr. Joe Mendelson takes us through the earliest signs of global amphibian declines and the timeline of how scientists went from dismissing the idea to finally accepting that there was a crisis to respond to.

Joe recounts how scientists worldwide initially dismissed disappearances as bad years until patterns converged at the 1989 World Congress of Herpetology and later evidence pointed to disease. The episode follows the slow recognition of chytridiomycosis, and Karen Lips’ documentation of a site’s chytrid arrival and subsequent crash. All of which kickstarted a global movement to respond to this crisis that is, unfortunately, not over yet.

Dr. Joe Mendelson III is Director of Research at Zoo Atlanta and adjunct professor at Georgia Tech University. He has dedicated his career to taxonomy and herpetology, and was among the first responders to the amphibian decline crisis. He is also a guitarist in the Atlanta-based science punk-rock band Leucine Zipper and the Zinc Fingers.
