For more than 10 years (2007-2018), the benthic macroinvertebrates of Bahía de Chamela (Mexican Pacific) were sampled at 31 sites (0-25 m depth). A total of 308 species of the five main classes of benthic molluscs were obtained (106 bivalves, 185 gastropods, 13 polyplacophorans, two scaphopods and two cephalopods). This is a significant increase in the number of species (246 new records) compared to the 62 species previously recorded more than 10 years ago. The distribution in the 31 localities of the bay is given for the first time for most of the species, together with information on its ecological rarity (incidence in the samples). Two families of bivalves (Veneridae and Mytilidae) and three families of gastropods (Calyptraeidae, Muricidae and Collumbellidae) comprised ~ 30% of all species. Ecological rarity was evident with 45 families (45.0%) with only one species and 178 species (57.8%) collected in one site and 67 (21.8%) in two sites. The molluscs of Bahía de Chamela represent 12.2% of all species recorded in the Mexican Pacific. Their biogeographic affinities are mostly related to the Tropical Eastern Pacific (TEP) including the oceanic islands and a few are restricted to the Tropical Mexican Pacific (TMP). Some have broader distributions to adjacent northern and southern temperate regions of the American Pacific, one to the western Atlantic, two pantropical (PAN) and two cosmopolitans (COS). The range distribution of each species was reviewed and updated, thus finding that seven species have extended their ranges of geographic distribution.

来自墨西哥巴伊亚德查梅拉的海洋软体动物的物种丰富度和生物地理亲和力

在十多年来(2007-2018),Bahíade Chamela(墨西哥太平洋)的底栖大型无脊椎动物在31个地点(0-25 m深度)进行了采样。共获得了五种主要底栖软体动物中的308种(106个双壳类,185个腹足类,13个多斜足类,两个腕足类和两个头足类)。与十年前以前记录的62个物种相比,该物种的数量(246个新记录)显着增加。首次首次给出了该海湾大多数物种在海湾31个地方的分布,以及有关其生态稀有性的信息(样本中的发生率)。约有30%的物种为两个双壳类(V属和and科)和三个腹足类(Ca形科,鼠科和bell科)。45个家庭的生态稀缺性显而易见(45。0%)只有一个物种,一个站点收集了178种(57.8%),两个站点收集了67种(21.8%)。巴伊亚德查梅拉的软体动物占墨西哥太平洋记录的所有物种的12.2%。它们的生物地理亲和力主要与包括海洋岛屿在内的热带东太平洋(TEP)有关,少数与热带墨西哥太平洋(TMP)有关。有些分布到美洲太平洋的北部和南部温带地区,一个分布到西大西洋,两个泛热带(PAN)和两个世界性(COS)。审查并更新了每个物种的范围分布,因此发现有七个物种扩展了其地理分布范围。巴伊亚德查梅拉的软体动物占墨西哥太平洋记录的所有物种的12.2%。它们的生物地理亲和力主要与包括海洋岛屿在内的热带东太平洋(TEP)有关,少数与热带墨西哥太平洋(TMP)有关。有些分布到美洲太平洋的北部和南部温带地区,一个分布到西大西洋,两个泛热带(PAN)和两个世界性(COS)。审查并更新了每个物种的范围分布,因此发现有七个物种扩展了其地理分布范围。巴伊亚德查梅拉的软体动物占墨西哥太平洋记录的所有物种的12.2%。它们的生物地理亲和力主要与包括海洋岛屿在内的热带东太平洋(TEP)有关,少数与热带墨西哥太平洋(TMP)有关。有些分布到美洲太平洋的北部和南部温带地区,一个分布到西大西洋,两个泛热带(PAN)和两个世界性(COS)。审查并更新了每个物种的范围分布,因此发现有七个物种扩展了其地理分布范围。有些分布到美洲太平洋的北部和南部温带地区,一个分布到西大西洋,两个泛热带(PAN)和两个世界性(COS)。审查并更新了每个物种的范围分布,因此发现有七个物种扩展了其地理分布范围。有些分布到美洲太平洋的北部和南部温带地区,一个分布到西大西洋,两个泛热带(PAN)和两个世界性(COS)。审查并更新了每个物种的范围分布,因此发现有七个物种扩展了其地理分布范围。
