50-70% of Guadeloupe’s lizards and snakes have become extinct since the 17th century.
A new study takes an opposite view of these trends by documenting the evolution of reptilian biodiversity in the Guadeloupe Archipelago in relation to the successive colonization of these islands by American and European Indian populations. This work was participated by scientists from prehistoric times to current laboratories in particular: civilization (UNESCO’s definition of culture is as follows  🙂PACEA, Environment and Anthropology CNRS (The National Center for Scientific Research, known by the acronym CNRS, is the largest …) / University.

This massive loss of biodiversity from the colonial period highlights the great stability of reptile biodiversity during earlier periods, although climate change and colonization of the Amerindian population had little impact on the environment. The results obtained also allow new connections to be established: a relationship between reptile size and patterns Life (Life is the given name 🙂 And the chances of their extinction, and one between the extinction of reptiles and post-colonial agricultural practices and the role of predators introduced in the colonial era such as conversation (The domestic cat (Felis silvestris catus) is a carnivorous mammal of the family …) And the Indian ferret.
