A species of endemic gecko, Phyllodactylus maresi, was rediscovered on Rábida Island in the Galápagos archipelago. The finding confirms its presence in this ecosystem after decades without reliable live records. Until now, only Holocene fossil remains and an image taken in 2012 had been accounted for.
During expeditions carried out in 2019 and 2021, researchers managed to detect live individuals of the reptile, a fact that was recently documented in a scientific publication. The rediscovery is considered a sign of success in the area’s ecological restoration programs.
Since 2011, Rábida Island has been the subject of restoration tasks led by the Galápagos National Park along with international organizations. Among the highlighted actions is the intensive control of invasive species such as rodents, which have been negatively impacting the native fauna.
These actions have allowed species like the gecko to have conditions to repopulate their habitats. The regeneration of the insular ecosystem shows that sustained conservation efforts can reverse processes of biodiversity loss.
Galápagos: restoration, science, and resilient biodiversity
The genetic and morphological studies carried out after the rediscovery of Phyllodactylus maresi reinforce the importance of maintaining scientific collections and genomic samples. These tools are key for the precise identification of species and the understanding of their evolutionary patterns.
The gecko is an example of how life can return when the main threats are eliminated. In this case, the removal of rodents allowed native reptiles to regain space and stability. This process, in turn, helps strengthen the insular food chains.
The archipelago was also the scene of another hopeful discovery: the coral Rhizopsammia wellington, considered missing for 25 years, was observed again in June. Its reappearance demonstrates the resilience of marine ecosystems when external pressures are reduced.
Conservation initiatives in Galápagos combine scientific monitoring, ecological restoration, and environmental education. These efforts aim not only to protect species but also to preserve the functional integrity of one of the planet’s most unique ecosystems.
The emblematic species of the archipelago
The Galápagos Islands are a natural laboratory where evolution manifests itself spectacularly. There, species that do not exist anywhere else in the world coexist, many of which were key in Charles Darwin’s studies.
Among the reptiles, the iconic giant tortoises and the marine iguanas stand out, unique in their ability to swim and feed underwater. They are also home to various species of finches, famous for their adaptations to different ecological niches.
The islands are home to mammals such as sea lions and dolphins, as well as endemic birds like the non-flying cormorant and the Galápagos albatross. In the sea, hammerhead sharks, rays, and green turtles complete an exceptional biodiversity picture.
This array of species makes Galápagos a critical point for global conservation. Its protection depends on the balance between controlled tourism, scientific research, and respect for an environment as fragile as it is valuable.
