百余年上海冬夏季降水与太平洋海温的相关关系及其年代际差异

利用上海1873—2001年的冬季和夏季降水量与太平洋海温资料，通过计算上海冬季和夏季降水量与太平洋海温的同期和超前相关以及滑动相关系数，讨论上海冬季和夏季降水年代际变化趋势及其与太平洋海温场的相关关系在不同年代和不同空间区域上的显差异．分析发现，上海冬季和夏季的降水均存在明显的年代际阶段性变化，但总体雨量增加的趋势不明显，降水量和太平洋海温的相关关系在不同年代和不同空间区域上存在着显的差异，这种年代际相关关系的差异可能是造成用统计方法做短期气候预测时产生不确定性的主要原因之一．因此作为短期气候预测的常用预报因子之一的太平洋海温场在进行统计预报的应用过程中，适当地考虑在不同时间尺度上的相关差异，将有利于提高预测的准确性和减少统计预测方法中的不确定性．     

The genus Coralaxius redefined,with the description of two new species (Crustacea: Decapoda: Axiidae)

The genus Coralaxius is rediagnosed, and the type species C. nodulosus (Meinert, 1877), the holotype of which was found to be identical with C. abelei Kensley and Gore, 1982, is redescribed. The two new species of Coralaxius are described, viz. C. galapagensis from the Galapagos Islands, and C. indopacificus from Fiji and the Comoro Islands. On the basis of carapace, gill and appendage characters, it is concluded that C. indopacificus is more primitive than the other two species. The genus is thought to have had a tethyan distribution, with the eastern Pacific representative being cut off from the western Atlantic form with the raising of the Isthmus of Panama.     

浅析联总援华物资中的美军剩余物资

抗日战争结束后，联合国救济善后总署(以下简称“联总”)紧急采购大批美军剩余物资，用以帮助中国恢复经济；来自太平洋战区的部分剩余物资货箱品名混乱，货单极不完备，给物资移交、处置工作造成极大困难，并在联总和行总之间引起一系列误会和龃龉；经过在上海就地装配修理，绝大部分剩余物资陆续投入使用，有力地促进了我国战后交通和工矿业的恢复。     

ENSO循环与行星位置的相互关系(Ⅰ):木星、土星视赤纬与赤道东太平洋海温的联系

 利用通用天文软件SKYMap Pro Version 8计算了木星和土星的月视赤纬,将其与ENSO循环及赤道太平洋关键区海温距平进行对比分析,发现两者存在明显联系,主要包括:木星视赤纬由正经过赤道变为负时,容易发生EL-Nino事件,而且事件持续时间较长,1980年代及以前发生过3次这样的情况都对应持续较长的EL-Nino事件,1980年代以后的2次EL-Nino事件群发期,其中心都发生在木星视赤纬从正向负转化期间.EL-Nino易发生在木星视赤纬的正极值和赤道附近,而负极值附近很少发生.LA-Nnia事件在1980年代及以前发生在木星视赤纬极值和赤道之间的中间视赤纬区域内,但1980年代以后,则容易发生在木星视赤纬负极值附近.一些EL-Nino事件发生年的木星视赤纬位置近乎在1条直线上,过去60年中有4条这样的直线,将EL-Nino事件分成4个组,每个组内都准确地由4个事件组成.当土星视赤纬靠近或离开赤道时(大概在±5°~10°),都会有EL-Nino发生,但在赤道区域却几乎不发生EL-Nino事件.     

Parasite community of the golden cownose ray Rhinoptera steindachneri Evermann and Jenkins 1891 (Chondrichthyes: Myliobatidae), in Acapulco Bay,Guerrero, Mexico

The parasite community of the ray Rhinoptera steindachneri from Acapulco Bay was examined and quantified; analyses were based on the sex of the host and the date of sampling. A total of 171 specimens of R. steindachneri were examined during July–August of 2010, and May and July of 2012. Twenty-one species of parasites were found: three species of Monogenea; eight adult and one larval species of Cestoda; one larval species of Nematoda; five species of Copepoda; two species of Isopoda; and one species of Hirudinea. Cestodes had the greatest species richness (43% of the total species), followed by the copepods (24%). Two species of cestode, Glyphobothrium sp. and Rhinebothrium sp., were collected only from adult rays. At the component community level, species richness showed statistically significant variation between 13 and 16 species, which is similar to previous reports for other species of rays. The parasite component communities and infracommunities of R. steindachneri exhibited similar patterns: high species number and low numerical dominance by a particular species of parasite. The differences of body size of male vs. female rays, and a change in diet and feeding behaviour with the age of R. steindachneri, are likely important factors in the structuring of their parasite communities.     

North Pacific species of the amphipod (Crustacea) family Stegocephalidae,with description of one new species and redescription of another

The genera and species of the family Stegocephalidae Dana, 1852 (Crustacea: Amphipoda) of the North Pacific, including the Bering Sea, are surveyed, and a key to the species is presented. One new species, Stegocephalus beringi n. sp., is described, and Stegocephalopsis ampulla (Phipps, 1774) is redescribed; S. vegae Oldevig, 1959 is synonymized with S. ampulla. Comments are given on the morphology of three additional species.     

Additions to the hydroids (Cnidaria) of the Galápagos,with a list of species reported from the islands

The hydroid fauna of the Galápagos Islands, Ecuador, is known largely from reports of collections made between 1932 and 1938 during several Allan Hancock Pacific Expeditions. Of some 100 nominal species (excluding Stylasteridae) reported from the archipelago overall, including species obtained during other expeditions, 81 are recognized as valid. An additional 15 species are added here, 14 of them based on collections undertaken between 1992 and 2000. Leptothecates account for 66 of the 96 species, while anthoathecates comprise the remaining 30. One previously undescribed leptothecate, Halopteris violae, sp. nov., is characterized and compared with H. tenella (Verrill, 1874) and H. minuta (Trebilcock, 1928), species it closely resembles. Gonothecae of Sertularella costata Leloup, 1940 are described for the first time. Plumularia galapagensis, nom. nov., is proposed as a replacement name for the invalid junior primary homonym Plumularia tenuissima Fraser, 1938b (not Plumularia tenuissima Totton, 1930). Under provisions of the International Code of Zoological Nomenclature, the widely used name Cladocoryne floccosa Rotch, 1871 is designated a nomen protectum and assigned precedence over its largely unknown senior synonym Hydra corynaria Bosc, 1797, which is reduced to the status of nomen oblitum. Balella irregularis (Fraser, 1938) from the Galápagos is considered conspecific with Balella mirabilis (Nutting, 1905) from Hawaii and Japan. Six new combinations are introduced: Bimeria laxa Fraser, 1938a is assigned to the genus Garveia Wright, 1859, as G. laxa (Fraser, 1938a); Tubularia integra Fraser, 1938a is assigned to Ectopleura L. Agassiz, 1862, as E. integra (Fraser, 1938a); Campanulina ramosa Fraser, 1938a is assigned to Opercularella Hincks, 1868, as O. ramosa (Fraser, 1938a); Bonneviella minor Fraser, 1938a is assigned to Scandia Fraser, 1912, as S. minor (Fraser, 1938a); Campanularia gracilicaulis Fraser, 1938a is assigned to Clytia Lamouroux, 1812, as C. gracilicaulis (Fraser, 1938a); Sertularia anceps Fraser, 1938a is assigned to Dynamena Lamouroux, 1812, as D. anceps (Fraser, 1938a). Hydroids of the Galápagos are moderately well known faunistically, at least in comparison with those of other areas in the Eastern Pacific Tropical Region.     

Use of morphological and molecular data to identify three new sibling species of the genus Munida Leach, 1820 (Crustacea,Decapoda, Galatheidae) from New Caledonia

Three cryptic species of the genus Munida from New Caledonia, previously identified as M. tuberculata Henderson, , M. notata Macpherson, and M. clinata Macpherson, , are described and illustrated. The three species are identified by subtle and constant morphological characters, which match clear differences in molecular sequences (16S rDNA and COI genes). The results also confirm the importance of several of these characters (e.g. length of the antennular and antennal spines) in the taxonomy of the genus Munida.     

New and little‐known species of Didemnidae (Ascidiacea,Tunicata) from Australia (Part 3)

The majority of the 58 species discussed, including 10 new species, were collected by scuba divers at 5–10?m in waters around Australia. Species are from Leptoclinides (11), Polysyncraton (11), Didemnum (19), Trididemnum (7), Lissoclinum (8), Clitella (1), and Diplosoma (1), and new species are in all except Trididemnum and Diplosoma. Additional characters (including a pyloric vesicle reported previously in the Holozoidae and several unrelated didemnid taxa) have been detected for the monotypic genus Clitella Kott, , which is recorded for only the second time. A review of known Australian ascidian species confirms the Didemnidae as the most speciose ascidian family in these waters. In this family, there appears not to be appreciable gene flow between tropical and temperate waters and few species have a continuous tropical–temperate range. A preponderance of Western Pacific non‐indigenous species is in the north, while indigenous species, some probably isolated from related tropical ones, are dominant in the temperate waters of the southern half of the continent. Although intraspecific variation and convergence obscures species differences, some aspects of the living organisms detected in in situ photographs contribute to identification. Keys to Australian didemnid species described since the publication of the Australian Ascidiacea part 4, Didemnidae (Kott ) are included.     

New species of Monstrilloida (Crustacea: Copepoda) from the Eastern Tropical Pacific

Monstrilloid copepods were collected from the oceanic island Isla del Coco in the Eastern Tropical Pacific; two undescribed species were found, one of Cymbasoma and one of Monstrillopsis. The first species, represented by females only, is distinguished by the structure of its fifth legs, the antennular armature and the position of the ovigerous spines. The new Monstrillopsis, represented by male specimens, is distinguished by its genital lappets and details of the antennule armature. The isolation of this island, 532 km from the mainland, and the limited dispersal means of monstrilloids suggest potential endemism of these species. A recent record of Cymbasoma tumorifrons from the Mexican Pacific was found to represent a new species of Cymbasoma. It can be distinguished from C. tumorifrons, probably a Mediterranean form, by its body shape and antennular armature. These findings double the number of monstrilloid species known from the Eastern Tropical Pacific.
