钩虾体内寄生棘头虫幼虫在中国的首次报道

钩虾(Gammarus sp.)是一类栖息于水底及聚集于水草丛的端足类动物.我国对钩虾的研究主要是种类鉴定,而且也主要是近几年的研究成果1.钩虾作为棘头虫的中间宿主,在国外已有很多报道2,3.然而在国内对棘头虫生活史的研究甚少,特别是对鱼类的棘头虫4.       

强壮藻钩虾的繁殖及胚胎发育的形态学观察

强壮藻钩虾隶属于节肢动物门甲壳纲端足目钩虾亚目的一种小型水生生物,在20世纪80年代初由任先秋首次记录并进行形态学描述,主要分布在中国黄海、渤海、东海、日本和北太平洋海岸。强壮藻钩虾主要生活在有机物丰富的海水中并常栖息于大型水草中,可全年在野     

THE TROPHIC ECOLOGY OF FRESHWATER GAMMARUS SPP. (CRUSTACEA:AMPHIPODA): PROBLEMS AND PERSPECTIVES CONCERNING THE FUNCTIONAL FEEDING GROUP CONCEPT

Gammarus spp. are widespread throughout a diverse range of freshwater habitats and can be the dominant part of many benthic macroinvertebrate assemblages, in terms of both numbers and/or biomass. Although the vast majority of studies have emphasized the herbivorous nature of Gammarus spp. and their ‘shredder’ functional feeding group (FFG) classification, we show that a far wider food base is exploited than has been previously acknowledged. This ‘plasticity’ as herbivore/predator is linked to the success of Gammarus spp. in persisting in and colonizing/invading disturbance-prone ecosystems. Intraguild predation and cannibalism are more common than previously realized. This behaviour appears to be a causal mechanism in many amphipod species replacements. Additionally, Gammarus spp. are major predators of other members of the macroinvertebrate community. Furthermore, while many studies have emphasized fish predation on Gammarus spp., we illustrate how this fish: amphipod, predator: prey interaction may be a two-way process, with Gammarus spp. themselves preying upon juvenile and wounded/trapped fish. We urge that a new realism be adopted towards the trophic ecology of Gammarus spp. and their role as predators and prey and that previously established FFG assumptions of both the food and the feeder be questioned critically.

A new freshwater species of the genus Jesogammarus (Crustacea: Amphipoda: Anisogammaridae) from northern Japan

-A new species of anisogammarid amphipod, Jesogammarus (Jesogammarus) mikadoi sp. nov., is described from freshwater habitats in northern Honshu, Japan. The species is distinguished from its congeners by having dorsal setae on pereonites 5-7 and pleonites 1-3.     

A new species of pelagic amphipod of the genus Lestrigonus (Crustacea: Amphipoda: Hyperiidea: Hyperiidae) from eastern Australia

A new species of pelagic amphipod, Lestrigonus ducrayi sp. nov.,from eastern Australia, is described and illustrated. It isvery similar to Lestrigonus bengalensis Giles, 1887, but isreadily distinguished by a relatively shorter telson (aboutone-third peduncle uropod 3) and, in mature males, pereonites1–5 are fused as in females. The two species often occurtogether in the same plankton sample; the new species beingmore abundant inshore, although both species seem to preferinshore waters. A key to the species of Lestrigonus is provided.
