Abstract
Paleontological and archaeological data collected since the 1950s from the Guadeloupe Islands allow modern and past occurrences of bird species to be compared and changes (colonization, extirpation and extinction) in avian communities over the last 30,000 years to be highlighted. Here we report data from 24 assemblages from sites spread across Basse Terre, Grande Terre, La Désirade, Marie Galante and Les Saintes dating from the Late Pleistocene, before the arrival of humans, to the Historical period, subdivided into five main periods: pre‑human, Archaic, Ceramic, Contact and Colonial. At least 55 taxa have been identified, belonging to 26 families and 16 orders. Approximately 65 % of the identified taxa are the first fossil occurrences documented for the Guadeloupe or Lesser Antilles Islands (36 taxa) and provide a wealth of information for reconstructing the past geographic distribution of avian communities. Furthermore, a large part of the bird species became extinct (2 taxa) or were extirpated (17 taxa) from one or more islands of Guadeloupe, primarily during the Colonial period. Our results show direct and indirect human impact to be the main factor underlying the loss of avian biodiversity in the archipelago. These results are part of a modification of the Caribbean terrestrial vertebrate biocenosis in the second half of the Holocene, via the extinction of a significant number of non-volant terrestrial vertebrates. Among the terrestrial birds, these changes lead to a few extinctions, but mainly, to the local disappearance or reduction in habitat size of most forest birds.
自20世纪50年代以来在瓜德罗普群岛收集的古生物学和考古学数据使鸟类物种的现代和过去发生的情况进行了比较,并突出了过去3万年鸟类群落的变化(殖民化,灭绝和灭绝)。在这里,我们报告了来自Basse Terre, Grande Terre, La dsamsiade, Marie Galante和Les Saintes的24个地点的数据,这些地点从晚更新世开始,在人类到来之前,到历史时期,细分为五个主要时期:前人类,古代,陶瓷,接触和殖民时期。目前已鉴定出至少55个分类群,隶属于16目26科。其中约65%的分类群是在瓜德罗普岛或小安的列斯群岛(36个分类群)首次发现的化石,为重建过去鸟类群落的地理分布提供了丰富的信息。此外,大部分鸟类物种在瓜德罗普岛的一个或多个岛屿上灭绝(2个分类群)或灭绝(17个分类群),主要是在殖民时期。我们的研究结果表明,直接和间接的人类影响是导致群岛鸟类生物多样性丧失的主要因素。这些结果是全新世下半叶加勒比陆生脊椎动物生物群落变化的一部分,通过大量非洄游性陆生脊椎动物的灭绝。在陆生鸟类中,这些变化导致少数物种灭绝,但主要是导致大多数森林鸟类的局部消失或栖息地面积缩小。
期刊介绍:
La revue Quaternaire créée dès 1964 par l"AFEQ sous le nom de Bulletin de l"AFEQ est devenue Quaternaire en 1990. Ce journal scientifique paraît au rythme de quatre numéros par an. La revue publie des numéros d"auteurs (par ordre d"arrivée des manuscrits après acceptation) ou des numéros thématiques sur proposition ou invitation par le comité de rédaction. Les articles (en langue française, anglaise ou allemande) traitant de tous les aspects du Quaternaire sont acceptés. La revue est publiée avec le concours du Centre National de la Recherche Scientifique.
