摘要

几内亚湾的特点是一个复杂的水文和支持高物种多样性。最近的一项研究表明,该地区可以被认为是稀有物种的避难所。2012年,在加纳海岸(几内亚湾)的R/V F. Nansen号上进行了密集采样,结果发现了大量底栖无脊椎动物,包括过硬壳类动物。初步调查表明,Cumacea的多样性很高,95%的物种是科学上的新物种。种数最多的属是竹属(Eocuma),共有7种;其中六种被证明是科学上的新发现,在这里进行了描述。此外,利用基于形态特征的系统发育树、贝叶斯二元马尔可夫链蒙特卡罗生物地理分析和文献资料等方法,分析了梭子鱼的全球分布。讨论了西非动物群的辐射中心。

Diversity of and biogeographic insights into the Atlantic Eocuma (Cumacea: Peracarida)
Abstract The Gulf of Guinea is characterised by a complex hydrology and supports a high species diversity. A recent study has indicated that the area can be considered a refuge for rare taxa. Intensive sampling off the coast of Ghana (Gulf of Guinea) in 2012 on board the R/V F. Nansen resulted in the discovery of a large number of benthic invertebrates, including peracarid crustaceans. A preliminary investigation demonstrated a high diversity of the Cumacea, with 95% of the species being new to science. The most species-rich genus was Eocuma with seven species; six of them proved new to science and are described here. Additionally, the global distribution of Eocuma was analysed with the help of a phylogenetic tree based on morphological characters, Bayesian Binary Markov chain Monte Carlo biogeographic analysis and literature data. The radiation centres of the west African fauna are discussed.

期刊介绍: The European Zoological Journal (previously Italian Journal of Zoology) is an open access journal devoted to the study of all aspects of basic, comparative and applied protozoan and animal biology at molecular, cellular, tissue, organ, organismal, population, and community-ecosystem level. Papers covering multiple levels of organization and integrative approaches to study animal form, function, development, ecology, evolution and systematics are welcome. First established in 1930 under the name of Il Bollettino di Zoologia, the journal now has an international focus, reflected through its global editorial board, and wide author and readership.
