dc.description.abstract | The Genovesa Marine Iguana is found only on the island of Genovesa in the Galápagos Islands, Ecuador. The extent of occurrence and area of occupancy is estimated at 28 km2 . The population size is poorly known and estimated at 900–15,000 total iguanas, with fewer than 9,000 mature individuals. Genetic data indicate a moderate effective population size. Overall population trend is unknown, but is subject to extreme reductions and fluctuations during El Niño events, which are predicted to intensify in the future with ongoing climate change. Genovesa Marine Iguanas are threatened by a region-wide increase in human population and visitation that has multiplied the impacts from marine pollution, habitat degradation, and chance of invasive species introductions and emergent diseases. Land-based tourist presence and intensity has been shown to have a significant overall negative effect on iguana health. This subspecies qualifies for listing as Critically Endangered. | |
