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.

The introduction of alien species is arguably the most important driver of biodiversity loss for oceanic islands. Our work seeks to evaluate the effects of alien invasive species, climate change, and other anthropogenic pressures on the biodiversity of the Galapagos Marine Reserve and the Eastern Tropical Pacific in order to better sustain coastal communities and prevent marine species extinction.
