摘要

通过对停泊在三个开放海域的沉积物捕集器获得的下沉颗粒的分析,首次探索了地中海东北部多胱氨酸放射虫的存在和多样性。共鉴定出30种,为阐明本研究中所遵循的物种概念提供了适当的参考和例证;已鉴定的种中有13种是刺虫,16种是纳塞拉虫,1种是Entactinarian。多样性最高的是爱奥尼亚遗址,在2014年11月期间共观察到23种,其中Nassellarian物种与Spumellarians物种数量相当;大量物种与杜布罗夫尼克附近亚得里亚海报道的动物群相同,但有趣的是,另有16种不是。在爱琴海北部和克里特海的地点观察到的放射虫多样性水平最低,最多只有3至4种。我们的观察也提高了对两种多胱氨酸物种的古生物地理知识,其中一种(Gonosphaera primordialis Jørgensen)以前在北半球和南半球高纬度地区已知,另一种(Qiuripylolena chikuchik Zhang和Suzuki)来自太平洋。

Diversity of polycystine radiolarians in sediment traps from the Ionian, North Aegean and Cretan Seas: A preliminary account

The presence and diversity of polycystine radiolarians in the North-Eastern Mediterranean Sea is explored for the first time through the analysis of sinking particles obtained from sediment traps moored in three open marine sites. In total, thirty species are identified for which we provide appropriate references and illustrations to clarify the species concept followed in this study; 13 of the identified species are Spumellarians, 16 are Nassellarians and one is an Entactinarian. The highest diversity is recorded in the Ionian site, in which 23 species were observed during November 2014, with approximately as many Nassellarian species as Spumellarians; a large number of species are in common with the fauna reported from the Adriatic Sea, off Dubrovnik, but interestingly, 16 others are not. The lowest levels of radiolarian diversity, with 3 to 4 species at best, were observed in the north Aegean and Cretan Sea sites. Our observations improve also the paleobiogeographic knowledge of two polycystine species, one of which (Gonosphaera primordialis Jørgensen) was known previously from the high latitudes of both the northern and southern hemisphere and the other (Qiuripylolena chikuchik Zhang and Suzuki) from the Pacific ocean.

期刊介绍: La Revue de micropaléontologie publie 4 fois par an des articles de intérêt international, consacrés à tous les aspects de la micropaléontologie. Les textes, en anglais ou en français, sont des articles originaux, des résultats de recherche, des synthèses et mises au point, des comptes rendus de réunions scientifiques et des analyses de ouvrages. La revue se veut résolument ouverte à tous les aspects de la micropaléontologie en accueillant des travaux traitant de la systématique des microfossiles (et de leurs équivalents actuels), des bactéries aux microrestes de vertébrés, et de toutes leurs applications en sciences biologiques et géologiques.
