Abstract:
The Southern Caribbean (SCA) represents the most productive ecoregion of the Tropical Northwestern Atlantic (TNWA) province. In order to assess the diversity of pelagic copepods in the ecoregion, we present an inventory based on unpublished data obtained from several oceanographic cruises made in oceanic and neritic waters of Venezuela (1967–1968). We complement this information with previous regional surveys to obtain a revised systematic checklist of the pelagic copepod species in the SCA. We included in our list a total of 346 species and 2 subspecies; up to 11 species represent new records. This study allowed us to: (1) expand the distributional range of some species within the TNWA, (2) record the occurrence, in the SCA, of all species known to 12 of 42 families to occur in the TNWA, (3) determine that the number of species of Corycaeidae and Paracalanidae in the SCA is greater than previously documented for the TNWA. Overall, the species accumulation curve resulting from our data analysis allowed us to determine that the diversity of pelagic copepods is underestimated; our estimations suggest that the potential species number that can be recorded in the SCA is 12 to 48% above the figure herein established.

摘要：
加勒比海南部（Southern Caribbean, SCA）为热带西北大西洋（Tropical Northwestern Atlantic, TNWA）生物地理区内生产力最为旺盛的生态区域。为评估该生态区内的浮游桡足类（pelagic copepods）多样性，本研究基于1967至1968年间在委内瑞拉远洋与近岸浅海水域开展的多次海洋科考航次所获取的未发表数据，编制了物种名录。本研究结合既往区域调查数据对该名录进行补充，最终形成加勒比海南部浮游桡足类物种的修订系统分类名录。本次名录共收录346个物种及2个亚种，其中多达11个物种为该区域的新记录种。本研究实现了以下三项成果：（1）拓展了部分物种在热带西北大西洋的分布范围；（2）记录了热带西北大西洋42个科中12个科的所有已知物种在加勒比海南部的出现情况；（3）证实加勒比海南部的亮剑水蚤科（Corycaeidae）与拟哲水蚤科（Paracalanidae）的物种数量均高于此前热带西北大西洋的相关记录。综合来看，基于本研究数据分析得到的物种累积曲线（species accumulation curve）显示，加勒比海南部浮游桡足类多样性被低估；研究估算表明，该区域可记录的潜在物种数量较本次名录收录的物种数高出12%至48%。
