Abstract

International audience; Marie-Galante Island (Guadeloupe, French West-Indies) has recently been the object of several paleontological investigations in order to characterize the evolution of its terrestrial vertebrate paleobiodiversity during the last 40 000 years. This paper consists in a synthesis these recently obtained results obtained by crossed studies of several large vertebrate fossil assemblages (mammal, bird, squamate, and amphibian) collected in Late Pleistocene and Holocene deposits. Our work reveals apreviously inconspicuous now-extinct Pleistocene and Holocene vertebrate biodiversity. We observed that this past diversity was recently modified to become very different from what it is nowadays. Indeed, while a small number of extinction or extirpation events can be related to the Pleistocene-Holocene climatic transition, the faunal community of the island is nearly completely modified during the last millenaries. These modifications include the arrival of several exogenous taxa, and an extinction/extirpation rate of native species between 54% and 100% depending of taxa.Our results suggest that human impact was the main factor driving the evolution of the island terrestrial faunal diversity. We also demonstrate a possible impact of Pre-Columbian human populations on the faunal diversity of Marie-Galante Island which however remains minor in respect to the overwhelming modifications possibly related to the European colonization and subsequent anthropization of the island.

Abstract

International audience; Palaeo- and neo-taphonomic analyses rarely consider the whole faunal spectra in a single study, and works concerning birds of prey as microvertebrate accumulators mostly focus on small mammals such as rodents. However, these predators often hunt and consume a large range of species, including small mammals but also amphibians, lizards, birds, insects and sometimes fishes. Remains of these taxa are frequently found in great abundance in palaeontological and archaeological context, especially in caves. It is thus mandatory to conduct global and multi-taxa taphonomic approaches in order to better characterize the predators at the origin of fossil microvertebrate accumulations and the taphonomic history of the deposits. The aim of this communication is to provide an example of such multi-taxa neo-taphonomic approach tested on falcon and owl pellets from Dominica (Lesser Antilles). We propose a new methodology allowing comparisons between different taxa (bats, amphibians, squamates, and birds) and also experiment a cross-validation process through the implication of two specialists for each group (ES+DC for small mammals, SB+CB for herpetofauna, MG+VL for birds) for a better reliability of the taphonomic observations.

Abstract

International audience; Le site de la Grotte Blanchard récemment fouillé sur l’île de Marie-Galante permet de décrire l’évolution des communautés de vertébrés de l’île depuis les 40 derniers millénaires. Il en ressort un fort renouvellement de la biocénose entre le Pléistocène supérieur et l’actuel, illustré par des taux d’extinction variant entre 30% et 70% selon le groupe de vertébrés considéré : oiseaux, chiroptères ou squamates. La chronologie des événements observés et leur confrontation aux archives environnementales, archéologiques et historiques permet de mettre en relation les modifications biogéographiques et les changements du milieu d’origine climatique (maximum d’aridité du LGM, réduction de la surface des îles et submersion des littoraux par la remontée eustatique fini-glaciaire) ou anthropique (exploitation du milieu et introduction de faune exogène). Il en ressort que les biocénoses insulaires tropicales des Petites Antilles sont peu sensibles aux variations paléoenvironnementales d’origine climatique, les variations de biodiversité observées étant essentiellement imputables à une anthropisation des paysages initiée par le peuplement amérindien de l’archipel et qui s’accentue au cours des périodes historiques.
