The insular Caribbean is home to an exceptionally rich and unique biodiversity, that faces many threats. Because of its island ecosystems, Caribbean biodiversity is particularly exposed to the threat of invasive exotic species. Among these species, reptiles have received relatively little attention from scientists and managers, unlike species considered more spectacular, such as mammals or lionfish. However, several species of reptiles have already invaded many Caribbean territories, at the expense of native species. The risk of an increased invasion or the arrival of new invasive species is further accentuated by the trade in exotic reptiles, air and maritime traffic between the islands and with the mainland, as well as mass tourism. As a result, it is urgent to increase our knowledge about these species and their invasion dynamics, in particular to be able to adopt appropriate management measures.

The MERCI project aims to complete scientific knowledge about several species of invasive exotic reptiles: geckos, anole lizards, freshwater turtles and iguanas. It also aims to implement concrete actions allowing the monitoring of these species, their management in the field, and more effective preventive measures in the territory of the Lesser Antilles (Guadeloupe, Dominica, Saint Lucia, Saint Vincent and the Grenadines ).
