Cryptic bivalves with descriptions of new species from the Rodrigues lagoon

This paper describes a number of new taxa in the Arcidae, Philobryidae, Mytilidae, Galeommatidae, Kelliidae, Cyamiidae, Carditidae, Thraciidae and Clavagellidae. A further 17 species are included as new to the malacofauna of Rodrigues. Most of the species included came from cryptic habitats, of which the most interesting are apparently cavernicolous and similar to those described from southern Japan. Other species were described from crevice or algal turf communities. The most understudied group is the Galeommatoidea with four species described as new and a further five with as yet unresolved taxonomy.     

Two new Tarphius species from Macaronesia (Coleoptera,Zopheridae)

Two new species of Tarphius are described: Tarphius desertaensis n. sp. sifted from saxicole lichens on the small islet of Deserta Grande, east of Madeira, and Tarphius jandiensis n. sp. from Fuerteventura, in the Canary Islands, where it lives in the upper parts of the massif of Jandía as a relict of the once more hygrophilous fauna that inhabited the island. Both species are of small size and have a fairly convex body.     

国家利益英语网络宣传效果调查与思考——以钓鱼岛为例

文章采用派生唯素的内容分析编码法（derived etic content analysis coding approach）,对国内外4家知名网站关于钓鱼岛问题的相关报道进行分析研究。结果发现：不同媒体对钓鱼岛问题的报道有明显的倾向性。西方媒体比较关注＂霸权政治＂、＂平衡发展＂、＂民族主义＂、＂中日邦交＂和＂领土争端＂,而中国媒体则强调＂钓鱼岛主权＂、＂钓鱼岛问题的合理性＂、＂和平发展＂和＂国家主权＂,而对＂民族主义＂、＂平衡发展＂和＂领土争端＂等问题的讨论相对较少,对＂霸权政治＂则几乎没有任何反驳。

High-resolution climate recorded in the δ13 C of Porites lutea from Nansha Islands of China

A Porites lutea core from Yongshu Reef of Nansha Islands covering 50_year growth history is analyzed for carbon isotopic composition with monthly and seasonal resolution, and the results show that the coral δ 13 C generally has clear yearly cycles. The calibration indicates that the coral δ 13 C can record the sunshine duration, total cloud cast and rainfall of the Yongshu Reef, and it also shows significant association to El Nio events. From 1950 to 1999, the δ 13 C shows a clear long-term declining trend, which indicates a decrease in the sunshine duration and an increase in cloud cast and rainfall over Yongshu Reef over the past fifty years.

Coral cover as a proxy of disturbance： A case study of the biodiversity of the hermatypic corals in Yongxing Island, Xisha Islands in the South China Sea

The Yongxing Island is the biggest island of Xisha Islands in the middle part of the South China Sea. It occupies 1.8 square kilometers of land area and has permanent residence on it. There are only a few papers on the coral community of the Xisha Islands, reporting the species composition, structure and zonations of the hermatypic coral community in 1970s. The present study describes the hermatypic coral community based on the quadrat survey after almost 30 years in Yongxing Island in August 2002. It was the first time to present the percent cover data of live corals of Yongxing Island via a systematic scheme of quantitative quadrat sampling. The average total percent cover of the live coral is 68.4%. We found the total percent cover （TPC） could be an idea proxy of the overall disturbance regime impinging on the coral community. TPC can be used as an integrated measure of disturbance to coral reef. Using this surrogate, the best fit relation between TPC of the live corals and species richness, species diversity, or the species evenness is the unimodal second-order polymorphic parabola equation. This result is expected by the intermediate disturbance hypothesis （IDH）. From the fitted parabola equations, we calculated the best TPCs corresponding to the maximal species richness, the highest species diversity, or the most evenness respectively. They are surprisingly stabilized between 55% and 58%. Coral cover is the basic parameter widely available for most observation, research or monitoring programs. The good qualitative characteristics of percent cover provide powerful tool for the experimental, theoretical and modeling studies of coral reef in response to the disturbance.     

南沙诸岛的法律地位

根据《联合国海洋法公约》第121条的规定,岛屿可以享有与大陆同等的海域范围,而不具备社会经济属性的岩礁则不能拥有专属经济区和大陆架。南沙群岛的归属争议归根结底来自对其岛礁周围海域自然资源的争夺,因此明确南沙诸岛的法律地位是解决主权争端的关键。在运用国际法基本原理,并结合各岛礁的地理信息以及经济价值加以系统分析中,对南沙诸岛的法律地位进行明确,以期在实践中为维护中国在南海的海洋权益提供理论依据。     

The terrestrial micro-arthropod fauna of the South Sandwich Islands

The South Sandwich Islands are an isolated maritime Antarctic volcanic island arc 550-600km south-east of South Georgia. The terrestrial biology of the islands, with emphasis on the unique habitats associated with volcanically warmed ground, was investigated in 1997 and compared with the data collected during the only previous (1964) terrestrial expedition to the archipelago. The terrestrial fauna includes 29 free-living micro-arthropod species (nine Collembola and 20 Acari) and two, currently unidentified, enchytraeid worms; a further eight parasitic and sublittoral Acari are recorded in the literature. Freshwater habitats are very restricted in the archipelago and no freshwater fauna was located. Supralittoral pools on a single island contained the marine isopod Cassidinopsis maculata. There are no endemic taxa and no shoreline invertebrates other than the supralittoral Archisotoma brucei (Collembola) and two Enchytraeidae. Diversity on individual islands is, in part, a function of available ice-free ground area. The majority of dominant species throughout the archipelago, Cryptopygus antarcticus (Collembola), Nanorchestes nivalis, Eupodes minutus, Alaskozetes antarcticus and Halozetes belgicae (Acarina), originate on other maritime Antarctic islands, while Ayersacarus tilbrooki (Acarina) is sub-Antarctic. Few (one to three) individuals of several other sub-Antarctic species were recorded by either 1964 or 1997 expeditions, but only Pilellus rykei (Acarina) was reported by both. None of the sub-Antarctic species thought to be associated with geothermally warmed ground in 1964 was confirmed in 1997, despite extensive sampling of the same sites. It is more probable that sub-Antarctic colonists frequently arrive on the South Sandwich Islands but are unable to establish longterm viable populations. Cryptopygus caecus, now widespread on Candlemas I., is a solitary exception to this generalization.     

The Cheilostomate Bryozoa (Bryozoa: Cheilostomatida) collected by the Spanish 'Antartida 8611' Expedition to the Scotia Arc and South Shetland Islands

The Cheilostome Bryozoa of the ‘Antartida 8611’ Expedition, collected by the Spanish Oceanographic Institution (Instituto Espanol de Oceanografia, IEO) during the Antarctic summer 1986–87 are listed. This expedition collected abundant material of benthic invertebrates at many stations in the Scotia Sea archipelagos and South Shetland Islands, of which 70 yielded Cheilostomate Bryozoa. Of 85 species found, 32 have been collected in areas where they were not previously known. Twenty of them are recorded north of their known limit of distribution and two recorded south. Most of these species are cited for the first time for the Scotia Arc, thus supporting the generally admitted homogeneity of the Antarctic fauna. The presence of Arachnopusia monoceros in the Southern Ocean is confirmed; a previously unknown variability in the colony shape of Kymella polaris is reported and the ovicell of Exochella umbonata is described. In addition, four species have been proposed as new to science, three of them, belonging to the genera Cellaria, Klugerella and Hippomonavella, described in the present work and one, Macropora georgiensis, included in a previous work. Together with the discussion of the new species of Klugerella, the specific composition of this genus is updated, with the assignation of Membraniporella aragoi (Audouin) and Membraniporella marcusi Cook to Klugerella. The examination of the inner side of the orifice and the frontal wall of three species of Hippomonavella reveals that the frontal is at least partially umbonuloid and that this genus is better accommodated in the family Bitectiporidae MacGillivray, 1895 than in Smittinidae Levinsen, 1909. Se presenta un listado de los Briozoos Queilostomados obtenidos en la campana ‘Antartida 8611’ del Instituto Espanol de Oceanografia (IEO) durante el verano antartico de 1986-87. Esta expedicion recolecto un abundante material de invertebrados bentonicos en un alto numero de estaciones de los archipielagos del arco del Scotia y las islas Shetland del Sur, de las cuales 70 contenian briozoos. De las 85 especies encontradas, 32 se han recogido en areas en las que no eran conocidas previamente. De ellas, 22 aumentan hacia el norte su limite de distribucion y dos hacia el sur. Muchas de estas especies se citan por primera vez en el arco del Scotia, corroborando la generalmente admitida homogeneidad de la fauna antartica. La presencia de Arachnopusia monoceros en aguas antarticas, que habia sido puesta en duda, se confirma; se describe una variabilidad antes no conocida de la forma colonial de Kymella polaris, asi como la ovicela de Exochella umbonata, que no habia sido encontrada. Ademas, cuatro especies se han propuesto como nuevas para la Ciencia, de las que tres, pertenecientes a los generos Cellaria, Klugerella e Hippomonavella, se describen en este trabajo, y la otra, Macropora georgiensis, se ha incluido en una revision del genero publicada anteriormente. En la discusion de la nueva especie de Klugerella, se actualiza la composicion especifica de este genero, anadiendo al mismo Membraniporella aragoi (Audouin) y Membraniporella marcusi Cook. Se pone de manifiesto que la pared frontal de Hippomonavella es al menos parcialmente umbonuloide y, dadas las caracteristicas de dicha pared y del orificio, se propone que el genero Hippomonavella esta mejor situado en la familia Bitectiporidae MacGillivray, 1895 que en Smittinidae Levinsen, 1909.
