This narrow and long channel is one of the three navigable passages connecting the Pacific and Atlantic Oceans and it is shared between Chile and Argentina. Within the framework of the ERANET Lac Project CLIMAR (http://climar.cnr.it/index.php/contact/) a modeling study was conducted to investigate the water circulation inside this Channel and in the surrounding areas in order to evaluate the effects of atmospheric forcing on the channel fluxes and main hydrodynamics. A high-resolution 3D hydrodynamic model based on the finite elements method was implemented to an extended domain covering the whole Patagonian Shelf, part of the Drake Channel and part of the South-Eastern Pacific Ocean. The model horizontal spatial resolution was varying between several km for open oceans up to 100 m for Ushuaya Bay inside the Channel. A full year simulation run was carried out to repro- duce the circulation inside the channel as generated by tides, atmospheric and thermohaline forcing. -

The material was collected during 12 summer expeditions organized from Diversity; 1997 to 2013. In all, 24 pelagic and 116 benthic taxa were recorded, most of them widely Distribution distributed Arctic-boreal species. The advection of different water masses from the shelf had a direct impact on the structure of the pelagic Malacostraca communities, resulting in the clear dominance of the sub-arctic hyperiid amphipod Themisto abyssorum in Kongsfjorden and the great abundance of Decapoda larvae in Hornsund. The taxonomic, functional and size compositions of the benthic malacostracan assemblages varied between the two fjords, and also between the glacier-proximate inner bays and the main fjord basins, as a result of the varying dominance patterns of the same assemblage of species. There was a significant drop in species richness in the strongly disturbed glacial bays of both fjords, but only in Hornsund was this accompanied by a significant decrease in density and diversity, probably due to greater isolation and poorer quality of sediment organic matter in its innermost basin. -
From the Southeast Australian Coast, with Comments on the Distribution and Habitat Preferences of Chondropodinae
Muvi schmallenbergi gen. nov., sp. nov. (Crustacea, Tanaidacea) from the southeast Australian coast, with comments on the distribution and habitat preferences of Chondropodinae Piotr Jóźwiak and Magdalena Błażewicz Department of Invertebrate Zoology and Hydrobiology, Faculty of Biology and Environmental Protection, University of Łódź, Łódź, Poland ABSTRACT Based on material collected from the shelf off southeast Australia (offshore of Portland), a new genus and new species, Muvi schmallenbergi gen. nov., sp. nov., of the tanaidacean family Metapseudidae, is described. Muvi is distinguishable from other genera within the subfamily Chondropodinae by having equally long antennular flagella. It also differs from other Chondropodinae by a combination of characters such as eyelobes with a group of visual elements, rostrum with smooth lateral edges, pereonites with lateral processes and pleotelson lacking lateral process, antennule article-1 with a single apophysis, maxillule inner lobe well-developed, labial palp bearing three distal setae, cheliped exopod well-developed and setose, pereopod-1 coxa with distinct apophysis, pleopods in five pairs, and uropod basis without apophysis. The genus Deidamiapseudes Sganga & Roccatagliata, 2016 is moved from Chondropodinae (Metapseudidae) to Apseudoidea incertae sedis. An identification key for the genera within Chondropodinae is given, and their distribution is discussed.

Initially it was found only in Corio Bay, but during the past fiveyears it has spread so that it now occurs throughout the western half of Port Phillip Bay. • Densities of Sabella in many parts of the bay remain low but densities are usually higher (up to 13/m2 ) in deeper water and they extend into shallower depths in calmer regions. • Sabella larvae probably require a 'hard' surface (shell fragment, rock, seaweed, mollusc or sea squirt) for initial attachment, but subsequently they may use their own tube as an anchor in soft sediment . • Changes to fish communities following the establishment of Sabella were analysed using multidimensional scaling and BACI (Before, After, Control, Impact) design analyses of variance. -

On the origin and evolution of Antarctic Peracarida (Crustacea, Malacostraca)* ANGELIKA BRANDT Zoological Institute and Zoological Museum, Martin-Luther-King-Platz 3, D-20146 Hamburg, Germany Dedicated to Jürgen Sieg, who silently died in 1996. He inspired this research with his important account of the zoogeography of the Antarctic Tanaidacea. SUMMARY: The early separation of Gondwana and the subsequent isolation of Antarctica caused a long evolutionary his- tory of its fauna. Both, long environmental stability over millions of years and habitat heterogeneity, due to an abundance of sessile suspension feeders on the continental shelf, favoured evolutionary processes of “preadapted“ taxa, like for exam- ple the Peracarida. This taxon performs brood protection and this might be one of the most important reasons why it is very successful (i.e. abundant and diverse) in most terrestrial and aquatic environments, with some species even occupying deserts. The extinction of many decapod crustaceans in the Cenozoic might have allowed the Peracarida to find and use free ecological niches. Therefore the palaeogeographic, palaeoclimatologic, and palaeo-hydrographic changes since the Palaeocene (at least since about 60 Ma ago) and the evolutionary success of some peracarid taxa (e.g. Amphipoda, Isopo- da) led to the evolution of many endemic species in the Antarctic. Based on a phylogenetic analysis of the Antarctic Tanaidacea, Sieg (1988) demonstrated that the tanaid fauna of the Antarctic is mainly represented by phylogenetically younger taxa, and data from other crustacean taxa led Sieg (1988) to conclude that the recent Antarctic crustacean fauna must be comparatively young. -

Diversity of Tanaidacea (Crustacea: Peracarida) in the World’s Oceans – How Far Have We Come? Magdalena Blazewicz-Paszkowycz1*, Roger Bamber2, Gary Anderson3 1 Department of Polar Biology and Oceanobiology, University of Ło´dz´,Ło´dz´, Poland, 2 Artoo Marine Biology Consultants, Ocean Quay Marina, Southampton, Hants, United Kingdom, 3 Department of Biological Sciences, University of Southern Mississippi, Hattiesburg, Mississippi, United States of America Abstract Tanaidaceans are small peracarid crustaceans which occur in all marine habitats, over the full range of depths, and rarely into fresh waters. Yet they have no obligate dispersive phase in their life-cycle. Populations are thus inevitably isolated, and allopatric speciation and high regional diversity are inevitable; cosmopolitan distributions are considered to be unlikely or non-existent. -

Frank Abstract Crustaceans possess a huge variety of body plans and inhabit most regions of Earth, specializing in the aquatic realm. Their diversity of form and living space has resulted in equally diverse eye designs. This chapter reviews the latest state of knowledge in crustacean vision concentrating on three areas: spectral sensitivities, ontogenetic development of spectral sen sitivity, and the temporal properties of photoreceptors from different environments. Visual ecology is a binding element of the chapter and within this framework the astonishing variety of stomatopod (mantis shrimp) spectral sensitivities and the environmental pressures molding them are examined in some detail. The quantity and spectral content of light changes dra matically with depth and water type and, as might be expected, many adaptations in crustacean photoreceptor design are related to this governing environmental factor. Spectral and temporal tuning may be more influenced by bioluminescence in the deep ocean, and the spectral quality of light at dawn and dusk is probably a critical feature in the visual worlds of many shallow-water crustaceans. -

This species closely resembles T. chotkarakde Bird & Bamber, 2000 and T. rawhitia Bird, 2011 in having the uropod with the endopod biarticulate and the exopod uniarticulate, but differs from them in the following characters: pereonite 4 as long as pereonite 5; mandibles lacking the molar; the number of simple setae on the antenna, propodal palm, and dactylus of pereopods 1–3; the number of spiniform setae on the cutting surface of the chelipedal dactylus; and the number of setae on the pleopods. We also determined a nearly complete nucleotide sequence for the 18S rRNA gene in T. japonica. In both sexes, Tanaopsis japonica sp. nov. bears serial ridges and grooves on the chela, antennule, and antenna. -

In an initiative to help further our understanding, invertebrate surveys over the past seven years have now revealed more than 500 species, many of which are endemic. This is an essential reference guide to these species. Illustrated with hundreds of representative photographs, it includes brief narratives on the biology and ecology of the major taxonomic groups and characteristic features of common species. It is primarily aimed at scientifi c observers, and is intended to be used as both a training tool prior to deployment at-sea, and for use in making accurate identifi cations of invertebrate by catch when operating in the HIMI region. Many of the featured organisms are also found throughout the Indian sector of the Southern Ocean, the guide therefore having national appeal.
