Ceuthonoe, a new genus with type species C. nezhai sp. n. commensal with euplectellid glass sponge (Hexactinellida: Euplectellidae), is described and illustrated, based on the material collected from Weijia Guyot, western Pacific. The new genus is distinguished by a combination of characters: body with 32 segments; 14 pairs of elytra; prostomium with prominent cephalic peaks and facial tubercle; aciculae and chaetae on tentaculophores; biramous parapodium, each ramus with a long aciculum penetrating epidermis, without supra-or subacicular process; and noto- and neurochaetae with unidentate tips. Ceuthonoe gen. n. is mostly silimar to genera of Polynoinae in morphology. However the phylogenetic analysis based on cytochrome c oxidase subunit I, 16S, 18S, and 28S genes suggested that this new genus was separated from the main branch of Polynoinae. The study also discussed the genera related to the new genus. 相似文献

钙扇藻属(Udotea)植物广为分布于热带海洋，特别盛产于珊瑚礁上。绝大多数种类的分布具有很大的海区局限性，例如，一般的大西洋种类(除了个别例外)不产于印度-西太平洋海区，反过来也一样。与它们的广泛热带分布相反，对其分类研究工作做的却很少。自从1911年Gepp等对这个属进行了系统分类，报道了15种；六十几年来，只增添了一个新种和一个新变种，还没有任何藻类工作者对这属的系统分类进行研究。除Gepp等报道了它们的内部结构以外，其他藻类工作者仅简略地描述了外部形态和一些藻丝的情况。
1957年和1958年，中国科学院海洋研究所曾派调查组到我国西沙群岛进行海藻调查时，采集了113号标本。经过我们的初步分析研究，西沙群岛的钙扇藻属的区系是非常丰富的。本文所报道的六个新种，仅只是西沙群岛钙扇藻区系的一部分。所用标本，包括模式标本都保存在中国科学院海洋研究所植物标本室。 相似文献

Abstract. Ecology and morphology of Alcyonium (Parerythropodium) coralloides were studied in different sites of the Eastern Atlantic and the Mediterranean. The species is extremely variable in size, colony shape and colour. In the Mediterranean population, encrusting red colonies are mostly encountered, although lobate colonies also exist. White and pink colonies are considered mutants, which tolerate the stable environment of deeper habitats better than the conditions encountered in shallow biotopes. Mediterranean colonies are dioecious and reproduce sexually. In the Eastern Atlantic, lobate pink colonies are the most common form, and show little variability. These (at least partly) parthenogenic populations are considered offspring from stray larvae from more southern regions. This explains the rather patchy distribution of the Atlantic populations, as compared to the widespread distribution throughout the entire Western Basin of the Mediterranean and the Adriatic Sea. A study of the most important systematic characters of the species (growth form, sclerites and solenial network) leads to the conclusion that coralloides belongs to the genus Alcyonium. As a result, coralloides being its type-species, the genus Parerythropodium will have to be suppressed. 相似文献

唇口目、无囊亚目、枝室超科(Order Cheilostomata;Suborder Anasca; Superfamily Cellularinoidea) 的双胞苔虫科(Bicellariellidae Levinsen，1909)的种类十分丰富，它的成员从潮间带至4000 多米的深海海底，从热带海洋到寒冷的极地海域，都有广泛的分布。
双胞苔虫科群体通常直立，有时多少平卧(recumbent)，甚至松散被覆(encrusting)在基质上。分枝多数为双列，有时单列或多列。个虫(zooids)通常钙化弱，但几丁化强。在一列个虫中，每一个虫从其前位个虫的背面末端生出，故个虫末端多少重叠在其后续个虫的始端部分上。前膜(frontal membranes)通常大，常占个虫整个前表面，但有时较小，始端裸壁发达。个虫两侧通常内卷，整个个虫常呈陀螺形。刺通常存在，有端刺(distalspines)和侧刺(lateral spines)。有柄鸟头体(pedunculated avicularia)为双胞苔虫科所特有。有时无刺也无鸟头体。卵胞通常存在。群体分歧方式和粗胞苔虫科(Family Scrupocellariellidae)不同(图1)：两支子分枝的内列个虫来自不同的虫室。为了叙述方便，可用字母统一标注与分歧有关的个虫。A是准备分岐的两个交替排列的始位个虫。B是与A连续交替、位于分枝另一侧的末位个虫。E是与分歧中轴密切相关的后续个虫，称为轴个虫;C与D是Y状分枝的一枝(子分枝)的外列个虫，分别是A和B的直接后续个虫，在形状上它们与A和B一致，与A和B的区别在于它们彼此分歧，以便让其他两个后续个虫E和F嵌在它们中间。E来自A，位于A的内侧，F来自B，位于B的内侧，即群体分枝分歧后的两支子分枝的内列(个虫)来自不同的个虫: F来自B，G来自E。这是双胞苔虫科的分歧模式。 相似文献

Abstract. Pinna nobilis Linnaeus 1758 is an endemic bivalve mollusc in the Mediterranean Sea, where it inhabits seagrass meadows, especially Posidonia oceanica (L.) Delile. It is the largest bivalve in the Mediterranean, reaching lengths up to 120 cm. In its natural habitat, P. nobilis lives with the anterior part of the valve buried in the seabed, attached to Posidonia rhizomes by byssus threads. This habit makes it impossible to measure its total length directly in situ. As the only way to determine the individual age is the relationship between age and total length, several equations have been proposed to estimate total length by relating it to the unburied parts of the shell. Such measurements are essential to ecological studies that consider age, growth, and population dynamics, and that evaluate the environmental factors that affect this species.Accurately estimating total length depends on the accuracy and precision of the method employed to measure the unburied shell parts. In this paper, we point out the lack of precision of the instruments and methods used until now; we also demonstrate the reason for this imprecision. A new device to measure unburied parts of Pinna nobilis with a precision comparable to that obtained when measuring extracted valves is described. This device is unaffected by substratum type and reduces measurement time. The latter is a very important feature, because these procedures are usually performed whilst SCUBA diving. Finally, a growth equation has been fitted to the measurements obtained with the new device from a population located in Moraira (Alicante, western Mediterranean). 相似文献

A new homoscleromorph sponge species was observed for the first time in 2002 along the coast of Provence (France) and since then, several investigations have been implemented. The new homoscleromorph species is devoid of skeleton and it is thus related to the Oscarella genus. Oscarella balibaloi sp. nov. has been found in several littoral submarine caves of the Western Mediterranean Sea (France and Spain). After several years of monitoring, we show that this sponge is becoming abundant in several locations. The species has a peculiar habit, often overgrowing massive sponges, gorgonians or some erected bryozoans. Oscarella balibaloi sp. nov. is thinly encrusting, with an irregular morphology, lobate surface, and soft and very slimy consistency. Its color is white to orange. At the cytological level, this new species is characterized by three distinct types of cells with inclusions in its mesohyl: one with vacuoles and the others with paracrystalline inclusions. The reproduction pattern is very similar to other Oscarella species. We also present a specific metabolic fingerprint and compare it to that of other Mediterranean Oscarella species. 相似文献

Precious corals represent peculiar substrata for several species of boring sponges that exploit their carbonatic scleraxis, strongly decreasing their commercial value. Here we describe a new species of the genus Alectona from Japan recorded in a colony of Paracorallium japonicum (Kishinouye, 1903). The spicular complement of the new species consists of diactinal spicules covered by mushroom-like tubercles, often modified into styloid forms, and fusiform amphiasters with two or sometimes four verticils, each generally made up of six short tubercled rays. A complete survey of the literature on boring sponges recorded in precious corals in the Mediterranean Sea and Pacific Ocean indicates that the species of the family Alectonidae are the most strictly associated to this kind of substratum. Their world distribution, in fact, partially or totally overlap that of their coral hosts. 相似文献

An excavating sponge, which covers extensive areas of limestone rock, has been found at several locations of the Eastern Mediterranean Sea. This zooxanthellate clionaid, brown with yellow oscula, may have an extension of several square meters under the β-form, similar to what has been described in coral reef areas. It has been observed at 3–30 m depth, generally in clear water in the Ionian Sea, Crete, Cyprus and Lebanon. The gross morphology and the spicule characters are described from all the collected specimens. The spicule complement, with variable tylostyles and rare, sometimes absent, thin spirasters, is compared with that of Cliona parenzani Corriero & Scalera-Liaci 1997 from the Apulian coast (Ionian Sea, Mediterranean Sea), and of several Caribbean and Indo-Pacific clionaid species, which display the same morphology and rather similar spicule characters. The sponge is tentatively identified as C. parenzani , although there are some differences with the type specimens in the highly variable spiculation, suggesting that it may represent a species complex similar to what is known for other species in the Caribbean and Indo-Pacific areas. Although the sponge appears to be closely related to large brown spreading clionaids from tropical areas and was previously practically overlooked in the Eastern Mediterranean, it does not appear to be a recent introduction. It is suggested that it could be a survivor in the warmer area of the Mediterranean of an ancient thermophilous fauna, which did not survive in the colder Western Basin during glacial episodes of the Pleistocene. 相似文献

This paper proposes a new network-based approach to analyse intergroup relations in fishing ports. The technique of clustered graphs is applied to the case of the Andalusian fishing ports to assess the balance between intra and inter-professional relationships. The patterns of sociability in Mediterranean and Atlantic fishing enclaves in the southern region of Spain were compared, examining their implications for participatory governance of marine resources. The personal networks of 53 fishermen, ship owners or skippers and key individuals of 18 Andalusian fisheries were analysed. The personal networks were compared in terms of fishing ground (Atlantic versus Mediterranean) and port type (by size and form of participation). The data of 45 individuals with whom each respondent usually interacts in the harbour was summarised in clustered graphs of intra-group and inter-group relationships between 8 professional roles in the harbour. Results show primarily that personal networks of Mediterranean ports are overall denser, in comparison with those of the Atlantic, which are more centralised and have a higher average betweenness. Secondly, in the Atlantic a clear difference of roles between ship owners and skippers is observed. A strong link between ship owners and the crew was found, and also between the ship owner and commercial roles in the Mediterranean. Small ports seem to be more apt for the artisanalisation of fisheries, as well as for the European Union’s Common Fisheries Policy. 相似文献
