New species of Brodskius,Rythabis, and Omorius (Crustacea: Calanoida) from deep Antarctic waters

Three new species of rare benthopelagic clausocalanoidean genera with sensory setae on the maxilla are described from female specimens collected during the German Antarctic expeditions ANDEEP I–III in 2002 and 2005, mainly from abyssal depths close to the sea bed. Brodskius abyssalis sp. nov. differs from congeners by the lack of rostral filaments, two setae on the second segment of antenna exopod, thread‐like tips of maxillary worm‐like sensory setae, and the length of spines of P5 exopod. Rythabis assymmetrica sp. nov. is distinguished from other species in the genus by asymmetrical posterior corners of the prosome, the shape of spermathecae, and setal numbers on the maxillulary distal basal endite plus endopod. Omorius curvispinus sp. nov. is characterized by strongly curved setae of the maxillipedal syncoxa, a comparatively long seta on the basis of antenna, a slightly swollen genital double‐somite, and the shape of spermathecae. The genera Brodskius, Omorius, and Rythabis are recorded for the first time from the southern hemisphere.     

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.     

Sipunculans and echiurans from the deep Angola Basin

Sipunculans and echiurans collected by the “DIVA 1” expedition by RV Meteor (Cruise M48/1) to the deep‐sea bottom of the Angola Basin are recorded. Seven species from five genera and two separate phyla are recognized; only the echiuran Pseudoikedella achaeta has not been recorded hitherto in the southern sector of the Atlantic Ocean. A gradient analysis using redundancy analysis (RDA) under the CANOCO package indicates the existence of a neat latitudinal gradient of sipunculans along the Angola Basin from the southernmost stations towards the northern ones. The local abundance of abandoned horny tubes of polychaetes at some of the sampling sites of the northernmost stations explains the dense aggregations of Nephasoma diaphanes. This species exhibits an opportunistic lifestyle inside empty polychaete tubes on the abyssal plains of the Angola Basin.     

中印共同崛起与双边关系的深度磨合

中印两国共同崛起是一个独特的历史性事件,这在推动地区和世界的巨大变革的同时,也深刻影响着双边关系的发展。在中印关系的深度磨合中,边界纠纷等老难题表现得更为复杂,经贸摩擦等新问题也涌现出来。互信鸿沟、自信与自卑交织及印度外交中的实用主义是这些问题难以解决的深层原因。中印必须耐心和妥善处理这些问题,才能维护和促进共同崛起的双赢局面。     

An abyssal species of Sagitta (Chaetognatha) from the North East Atlantic

A Chaetognath species new to science, Sagitta abyssicola is described from specimens taken at abyssal depths (3500–4000 m) in the north east Atlantic Ocean and comparisons are made with related species of the ‘planctonis’ group namely S. planctonis Steinhaus, 1896, S. zetesios Fowler, 1905 and S. marri David, 1956. Ecological data are provided.

新型双向冲击发电装置在波浪能发电中应用

在对海洋的开发利用中,海洋波浪能的开发方法太过复杂、单一。针对沿海海浪方向调查分析,设计出一种双向海洋波浪能发电装置,并对其具体结构和工作原理作了详细描述,该装置巧妙的工程设计,可以连续不断产生电能,由于海浪冲击和退去均会带动叶轮旋转产生机械能,可以将此转化为电能,在该发电装置得到推广应用的前提下,其有极大的提升空间和广阔的应用前景。     

开发西北热潮中的边疆矿产资源调查——以“中国西北科学考查团”为例的研究

“中国西北科学考查团”在野外工作的6年，正值中国社会开发西北热潮蓬勃兴起之时，考查团的工作对开发西北热潮起到了推波助澜的作用。中国地质学者对西北地区矿产资源给予了极大的关注，并取得了举世瞩目的成果。通过对地质考察报告的解读，总结中国学者在矿产资源调查方面的贡献及其社会影响，分析中国学者以及中国社会关注边疆矿产资源的原因。
