Distribution quaternaire d’un escargot rare en Guadeloupe, amphibulima patula (Brugière, 1789) (mollusca; amphibulimidae): implications paléoenvironnementales et écologiques

Abstract

The islands of Guadeloupe are small oceanic islands that home to an original terrestrial mollusc fauna comprising twelve species endemic to the islands themselves and thirteen species endemic to the Lesser Antilles. With a total of seventy-three taxa characterized to species or subspecies, the Guadeloupean terrestrial molluscs form a rich, highly varied faunal community (Charles, 2016), and represent a potential source of powerful palaeoenvironmental proxies. However, Quaternary land snails are

A fossil Diploglossus (Squamata, Anguidae) lizard from Basse-Terre and Grande-Terre Islands (Guadeloupe, French West Indies)

“…. A combination of these two factors, limited geographical distribution and human-induced environmental changes are also evoked by Lenoble et al 46. to explain the recent extirpation of the terrestrial mollusk Amphibulima patula from several Guadeloupe islands, and could also have influenced the extirpation of galliwasps.…”

“…A combination of these two factors, limited geographical distribution and human-induced environmental changes are also evoked by Lenoble et al . 46 to explain the recent extirpation of the terrestrial mollusk Amphibulima patula from several Guadeloupe islands, and could also have influenced the extirpation of galliwasps. The role of exogenous predators (mongoose, cat, dogs, rat…), which are often evoked as one of the main factors of the extinction of insular squamates in the Caribbean 47 48 could also be considered as a key factor.…”
