In the heart of the Galapagos Islands, a tiny, unexpected hero emerged in 2002 that would change the course of conservation. The Australian ladybug (Novius cardinalis), small in size but immensely effective, became a crucial ally in the fight against an invasive insect that threatened to devastate the endemic flora of these islands. This is the story of how science, innovation, and nature itself came together to help preserve one of the most valuable biological treasures on the planet.

Two groundbreaking studies led by Stephen Blake, Ph.D., assistant professor of biology at Saint Louis University and Sharon L. Deem, DVM, Director of Saint Louis Zoo Institute for Conservation Medicine, in collaboration with the Charles Darwin Foundation (CDF) and teams of multidisciplinary scientists shed light on crucial aspects of the conservation of two critically endangered giant tortoise species endemic to the Island of Santa Cruz, Chelonoidis porteri and Chelonoidis donfaustoi. Both studies offer valuable insights into the challenges these emblematic species face and the strategies needed to ensure their survival in the face of potential future habitat alteration and climate change.
