Nuevos registros del geco pestañudo (Aristelliger georgeensis) en la Reserva de la Biósfera Seaflower, Colombia

The Saint George Island Gecko is a Caribbean species recorded on the coasts and islands of Mexico, Belize and Honduras, and prefers rocky substrates, trees and shrubs. Its distribution in Colombia is limited to the archipelago of San Andrés, Providencia and Santa Catalina in the Seaflower Biosphere Reserve, where it has been recorded on the three most populated islands and on Roncador Key. During the scientific expeditions to the Reserve between 2014 and 2021, the search for this species was intensified through surveys in the emerged areas (islands and cays) of Serranilla, Serrana, Roncador, Alburquerque, Providencia and Santa Catalina. This species of gecko was recorded in all the localities visited, which broadens our knowledge of its geographic distribution. Since this is a nationally threatened species, these new records represent potential opportunities for its conservation. However, the introduced and invasive species recorded in most localities (i.e., Rattus spp., Gallus gallus domesticus, Hemidactylus frenatus and Periplaneta americana) pose a threat to this gecko and require urgent management measures.
