The hermit crab Sympagurus dimorphus (Anomura: Parapaguridae) at the edge of its range in the south-western Atlantic Ocean: population and morphometry features

Sympagurus dimorphus is one of the 12 hermit crab species recorded for Argentinean waters. Despite the high abundance registered in some scallop fishing grounds, its biology remains little known. In the present study, we analysed some population features of S. dimorphus living in symbiosis with Epizoanthus paguricola from a series of samples taken in the Argentine Sea, south-western Atlantic Ocean. Our results showed that S. dimorphus was commonly found from 40ºS to lower latitudes, in a patchy distribution along the shelf-break front. The overall sex ratio was 1:1. The smallest ovigerous female measured 6 mm in cephalothoracic shield length and this size was used as parameter to define the size of juveniles. The sex ratio size class pattern corresponded to Type IV or anomalous curve. S. dimorphus is a dimorphic species, as evidenced by the larger size of the males and the positive allometric growth of the right cheliped. The species also showed asymmetry, with the left uropod always larger than the right one. To the best to our knowledge, this is the first report on population features and relative growth for a member of the genus, based on long-term sampling. This species presents a patchy distribution along the shelf-break of Argentina. Its density tended to decrease over the five-year sampling period regarding the recruitment of hermits associated with colonies of zoanthids. In addition, the relatively homogeneous nature of this refuge does not seem to influence the growth of the hermit crab, which presents sexual dimorphism in relation to the sex/size conditions.     

Three abdominal parasitic isopods (Isopoda: Epicaridea: Bopyridae: Athelginae) on hermit crabs from China and Hong Kong

Three bopyrid isopods of the subfamily Athelginae parasitizing hermit crabs collected in Chinese waters are discussed and described in this paper. Athelges takanoshimensis Ishii, 1914 Ishii, S. 1914.

宋初隐逸诗歌艺术风格探析

宋初隐逸诗人诗学＂晚唐＂宗贾岛,苦吟琢句,又吸取了山水田园诗派的艺术特长,故呈现出较为独特的艺术风貌。诗歌创作格调高雅绝俗,诗境清苦荒寒,时见冲淡闲逸之趣,整体诗风趋于平淡自然。其诗歌艺术主要是对晚唐五代诗风的继承,但他们摆脱功利主义专门致力于纯自然的题材,清新幽远的诗风在宋初诗坛独树一帜。     

唐宋之际隐逸文化的嬗变——以徐积为中心的考察

北宋学者徐积一生积极用世,身后却被赐谥处士。宋代类似赐处士号的数量明显增加,不少致仕官员与任学官者也被认定为隐士,体现出唐宋问隐逸文化的深刻变化。它表明宋廷开始改造传统隐逸文化内涵,实质是将隐逸文化的不合作内涵替换以合作,这是一种被隐逸,可称之为“赐隐”,是宋以下集权化的一项举措。     

Pattern of shell occupation by the hermit crab Pagurus exilis (Anomura,Paguridae) on the northern coast of São Paulo State,Brazil

The purpose of this study was to determine the shell occupation pattern of Pagurus exilis using the percentage of shell types that were occupied and the morphometric relationship between hermits and occupied shells. Specimens were collected monthly from July 2001 to June 2003. A total of 1737 individuals were collected, occupying 19 gastropod shell species. Buccinanops gradatum (82%) was the most occupied shell, followed by Natica isabelleana (6.4%), Stramonita haemastoma (3.2%), and Cymatium parthenopeum (2.2%). There was a differential shell utilization pattern between sexes; males occupied larger and heavier shells while the non‐ovigerous females occupied the lightest ones. Pagurus exilis occupied more bare shells instead of incrusted ones. Buccinanops gradatum was the most occupied shell species as a function of its availability in the survey, and this occupation is strongly associated with the higher internal volume presented by these shells.     

道不行乘桴浮于海——论孔子隐逸思想本质

孔子的主要思想是积极入世的,但在他的思想体系中也有隐逸思想的存在。在《论语》中,孔子多次谈到隐逸的问题,“道不行,乘桴浮于海”正是他隐逸思想的特殊表达,由此可以探析孔子隐逸思想产生的深刻原因和突出特点。
