Abstract

The Canary Islands constitute one of the major marine biodiversity hotspots in the eastern-central Atlantic, with decapod crustaceans being a highly representative group in the benthic environment due to their vast diversity of taxa and occupied ecosystems. This study identifies three significant milestones corresponding to the publication of comprehensive decapod checklist for the Canary Islands in 1973, 1995, and 2018. The lists of coastal benthic decapod species (0–300 m depth) were revised and updated, indicating the biogeographic pattern and vertical distribution range of each species in the region. Changes in the composition of the biogeographic patterns of coastal decapods in the Canary Islands were analysed to evaluate whether they could be considered as a useful indicator of the tropicalization process in the region. Particular attention was paid to variations in the percentages of species with warm water affinity versus those with Atlanto-Mediterranean preferences, with the former showing a clear upward trend.

沿海底栖十足目动物生物地理格局的变化：过去 50 年加那利群岛热带化的指标

加那利群岛是大西洋中东部主要的海洋生物多样性热点地区之一，由于其分类群和所占生态系统的巨大多样性，十足目甲壳类动物是底栖环境中极具代表性的群体。本研究确定了三个重要的里程碑，分别是 1973 年、1995 年和 2018 年出版的加那利群岛十足目甲壳动物综合名录。对沿海底栖十足目物种清单（0-300 米深度）进行了修订和更新，指出了每个物种在该地区的生物地理格局和垂直分布范围。分析了加那利群岛沿海十足目动物生物地理格局组成的变化，以评估这些变化是否可被视为该地区热带化进程的有用指标。特别关注了温水亲缘物种与亚特兰大-地中海亲缘物种的百分比变化，前者呈明显上升趋势。

期刊介绍： Estuarine, Coastal and Shelf Science is an international multidisciplinary journal devoted to the analysis of saline water phenomena ranging from the outer edge of the continental shelf to the upper limits of the tidal zone. The journal provides a unique forum, unifying the multidisciplinary approaches to the study of the oceanography of estuaries, coastal zones, and continental shelf seas. It features original research papers, review papers and short communications treating such disciplines as zoology, botany, geology, sedimentology, physical oceanography.
