Abstract The northern Chilean coast is characterized by its high productivity and diversity due to the presence of the cold, nutrient-rich water of the Humboldt Current. In this scenario, the rocky shore provides many microhabitats for invertebrates such as crustaceans. The aim of the present study was to analyse potential species interactions using probabilistic models and contingency tables. In this particular case we analysed the potential interactions between two sympatric intertidal decapods, Cyclograpsus cinereus and Petrolisthes granulosus , on the rocky shores of Cifuncho Bay, an isolated bay in the north of Chile. The results revealed that both species had a uniform pattern, that was adjusted to a binomial distribution for C. cinereus , and a Poisson distribution for P. granulosus . These results are probably due to territorial behaviour, and this was corroborated by the results of the contingency table, which denoted the independence of both species. These results would not coincide with classical observations of intertidal decapods on rocky shores of continental Chile, as those denoted a gregarious pattern. However, on the other hand, the present results do not explain any details about potential interactions between the two species here analysed.
智利北部海岸的特点是其高生产力和多样性,由于洪堡流的寒冷,营养丰富的水的存在。在这种情况下,岩石海岸为甲壳类等无脊椎动物提供了许多微栖息地。本研究的目的是利用概率模型和列联表分析潜在的物种相互作用。在这个特殊的案例中,我们分析了在智利北部一个孤立的海湾Cifuncho湾的岩石海岸上,两种同属潮间带十足类动物Cyclograpsus cinereus和Petrolisthes granulosus之间的潜在相互作用。结果表明,这两个物种具有统一的分布模式,对C. cinereus调整为二项分布,对P. granulosus调整为泊松分布。这些结果可能是由于领土行为,这一点得到了列联表结果的证实,列联表表明了两个物种的独立性。这些结果与智利大陆岩石海岸的潮间带十足类动物的经典观察结果不一致,因为这些观察结果表明了一种群居模式。然而,另一方面,目前的结果并没有解释任何关于两个物种之间潜在相互作用的细节。

Abstract Two cylindrical crabs, Ixa cylindrus (Fabricius, 1777) and Ixa edwardsii Lucas, 1858 are herein recorded for the first time from the coastal waters of the eastern Arabian Sea. Both species were collected from the bycatch landing of the commercial demersal trawlers operated along the Gujarat coastal region, northwest coast of India, between 20 and 80 m depth. Both species have been recorded from the Bay of Bengal on the east coast of India, but there is no detailed information available on their taxonomic identification and global distributional records.

Abstract Capitulum mitella is an important species in the intertidal ecosystem and in the economy in China. This study explored the genetic diversity and population structure of C. mitella using mitochondrial 16S ribosomal subunit (16S rRNA) gene sequences. The researchers sequenced a 527 bp fragment of 16S rRNA from 390 samples collected from six localities along Western Taiwan Strait and identified 45 distinct haplotypes with an average haplotype diversity ( h ) of 0.451 and an average nucleotide diversity ( π ) of 0.00124. The pairwise statistics and AMOVA indicated a lack of significant population structure. The results indicated a recent expansion of the population of C. mitella in the study area. This expansion, combined with the species’ high dispersal capabilities, limited physical barriers, and the influence of oceanic currents, may be the factors contributing to its current phylogeographic structure. This study provides particularly important information for managing and protecting the resources of C. mitella in Southern China.
摘要半头草(Capitulum mitella)是中国潮间带生态系统和经济中的重要物种。本研究利用线粒体16S核糖体亚基(16S rRNA)基因序列研究了mitella的遗传多样性和群体结构。研究人员从台湾海峡西部6个地区收集的390份样本中测序了一个527 bp的16S rRNA片段,鉴定出45种不同的单倍型,平均单倍型多样性(h)为0.451,平均核苷酸多样性(π)为0.00124。两两统计和方差分析表明种群结构不明显。结果表明,研究区米特拉蝇种群近期有扩大的趋势。这种扩张,加上物种的高扩散能力、有限的物理屏障和洋流的影响,可能是造成其当前系统地理结构的因素。本研究为中国南方密草资源的管理和保护提供了重要的信息。

Abstract Many species of hermit crabs, such as Calcinus and Clibanarius spp., live on the rocky shores of tropical and warm temperate regions. During low tides, some of these species climb out of the tidal pools onto rock surfaces exposed to the air. In the genus Calcinus , however, such ‘Air-exposure (AE) behaviour’ was only known previously from Calcinus laevimanus . During a field study of the hermit crab fauna on Amami Oshima Island, Kagoshima, Japan, the AE behaviour of Calcinus elegans (Decapoda, Diogenidae) was observed on rocky shores. Moreover, the repeatability of the AE behaviour was confirmed. Therefore, we documented the AE behaviour of C. elegans as a second record of AE behaviour among Calcinus species by providing videographic evidence. The findings indicate that the AE behaviour has evolved in a broader range of Calcinus species than was previously assumed.
寄居蟹(Calcinus和Clibanarius spp.)生活在热带和暖温带的岩石海岸。在退潮时,其中一些物种爬出潮汐池,爬到暴露在空气中的岩石表面上。然而,在Calcinus属中,这种“空气暴露(AE)行为”以前只从Calcinus laevimanus中知道。在对日本鹿儿岛奄美大岛寄居蟹区系的野外调查中,对岩岸边的寄居蟹(Calcinus elegans,十足目,菊科)的AE行为进行了观察。此外,声发射行为的重复性得到了证实。因此,我们通过录像证据记录秀丽隐杆线虫的声发射行为,作为钙科动物中声发射行为的第二记录。研究结果表明,声发射行为的进化范围比之前假设的更广。

A new species of the wholly freshwater hymenosomatid crab genus Limnopilos Chuang & Ng, 1991, is described from Tonle Sap River in the lower Mekong drainage, Cambodia. This is the fourth species known, and the second one from Indochina. The type species, of Limnopilos, L. naiyanetri Chuang & Ng, 1991, was from the Chao Phraya drainage to the west in central Thailand. The new species is characterized by the presence of a rostrum, relatively shorter ambulatory legs and a different structure of the male first gonopod. Limnopilos sumatranus Naruse & Ng, 2007, is also recorded from southern Peninsular Malaysia for the first time.

The green tiger shrimp, Penaeus semisulcatus, is a commercial species supporting important fishery along the Palk Bay coasts. It is a much sought-after seafood commodity influencing the livelihood of the local fishers. This study aims to investigate the fecundity of the species in relation to its morphometry. Fecundity is an index of reproductive capacity used to calculate a stock’s reproductive potential and the egg’s survival. The absolute fecundity of the shrimp ranged from 26 100 to 750 000 ova alive per female, and the mean absolute fecundity from 59 100 to 583 000 ova alive per female. The relationship between fecundity and the morphometric measurements showed a positive exponential correlation. One-way ANOVA indicated a significant difference in the different size classes’ carapace length, total weight, ovary weight, absolute fecundity, stomach weight, and gastrosomatic index. There was no significant difference between the relative fecundity and the gonadosomatic index. This study provides insight into the reproductive potential of P. semisulcatus for efficient management of the resource in Palk Bay, Tamil Nadu, India.
半沟斑对虾是一种商业物种,为帕尔克湾沿岸的重要渔业提供支持。它是一种备受追捧的海鲜商品,影响着当地渔民的生计。本研究旨在研究该物种的繁殖力与其形态计量学的关系。繁殖力是一种衡量繁殖能力的指标,用于计算股票的繁殖潜力和卵子的存活率。虾的绝对繁殖力在26 100至750 000个卵子,平均绝对繁殖力为59 100至583 000个卵子存活。生殖力与形态计量测量之间的关系显示出正指数相关性。单因素方差分析表明,不同大小类的甲壳长度、总重量、卵巢重量、绝对繁殖力、胃重量和胃体细胞指数存在显著差异。相对繁殖力和性腺指数之间没有显著差异。本研究深入了解了印度泰米尔纳德邦帕尔克湾半溃疡假单胞菌的繁殖潜力,以有效管理该资源。

This present paper presents an inventory of benthic Malacostraca in the Gulf of Oran. The softbottom crustacean fauna was studied between February 2021 and September 2021. Samples were collected from 8 coastal stations. The class Malacostraca was represented with 2 subclasses, Eumalacostraca and Phyllocarida. Sixty-one species and 290 individuals belonging to seven crustacean orders (Amphipoda, Decapoda, Isopoda, Tanaidacea, Mysida, Lophogastrida and Leptostraca) were identified. Amphipoda were represented with the highest number of species (36) followed by Decapoda (11) and Isopoda (6). Tanaidacea and Mysida were poorly represented, with 3 and 2 species, respectively. Lophogastrida and Leptostraca were both represented by only one species. Among the crustaceans encountered, Ampelisca was the most dominant genus. The present inventory indicates that the carcinological fauna in the Gulf of Oran is less diversified than it is in other zones that have been studied on the Algerian coast (Gulf of Arzew, Bay of Bou-Ismail, and Bay of Algiers).
本文介绍了奥兰湾底栖马拉斯卡的清查情况。在2021年2月至2021年9月期间对软底甲壳类动物群进行了研究。样本采集自8个沿海站点。Malacostraca纲由Eumalacostraca和Phyllocarida两个亚纲代表。共鉴定出甲壳纲7目(片足目、十足目、等足目、足足目、足足目、足足目、细足目)61种290个个体。其中,片足目(36种)最多,其次是十足目(11种)和等足目(6种),田足目(3种)和田足目(2种)较少。Lophogastrida和Leptostraca均为1种。在遇到的甲壳类动物中,Ampelisca是最占优势的属。目前的清单显示,奥兰湾的致癌动物群的多样性低于阿尔及利亚海岸研究过的其他地区(阿尔泽湾、布伊斯梅尔湾和阿尔及尔湾)。
