Rare Species Re-emerges in the Galápagos Islands Following Extinction
In the remote and biodiverse Galápagos archipelago, a significant milestone has been achieved in the conservation of the endemic leaf-toed gecko (Phyllodactylus maresi). Once thought to be extinct, this species has made a remarkable comeback on Rábida Island, thanks to a targeted rewilding project that aimed to restore the island's ecosystems [1][2][3].
The project, completed in 2012, focused on the eradication of invasive rats from the island. The removal of these non-native predators allowed native species, like the leaf-toed gecko, to recover and reclaim their habitats [4]. This milestone exemplifies the power of carefully planned conservation interventions in rebalancing fragile island ecosystems and enabling biodiversity to bounce back dramatically.
The genetic analysis of the leaf-toed gecko on Rábida Island provides valuable insights into the evolving nature of wildlife conservation. The geckos on Rábida Island have been found to be genetically distinct from other populations of the species found on different islands, suggesting that they may have evolved separately [5]. This genetic distinction could warrant consideration as an Evolutionary Significant Unit (ESU).
The first live specimen of the leaf-toed gecko was found on Rábida Island in 2012, marking the beginning of the gecko's resurgence. Since then, the island's ecosystems have shown signs of regeneration, and the gecko has reemerged as a common sight. The gecko, measuring about eight centimeters, was known only through 5,000-year-old fossils until recent years [6].
The conservation of the leaf-toed gecko on Rábida Island serves as a case study for the importance of tailoring conservation efforts to the unique genetic characteristics of a species. It also underscores the need for continued research and targeted conservation efforts in the Galápagos Islands, which face ongoing challenges posed by invasive species [7].
The rediscovery and conservation of the leaf-toed gecko on Rábida Island is a beacon of hope and a model for similar conservation efforts worldwide. A recent study published in PLOS ONE provides detailed insights into the gecko's return, offering valuable lessons for future conservation initiatives [8]. The gecko's return is an extraordinary success in conservation and a testament to the power of targeted conservation efforts.
