One potential driver Hadal for species diversification might be allopatry caused by geographical barriers, such as ridges or trenches, or Ecology physiological barriers associated with depth. We analyzed biodiversity and biogeography of 21 morphospecies of Sea of Okhotsk the deep-sea isopod family Haploniscidae to investigate barrier effects to species dispersal in the Kuril- Deep sea Kamchatka Trench (KKT) area in the Northwest (NW) Pacific. Our study is based on 2652 specimens from three Abyssal genera, which were collected during the German-Russian KuramBio I (2012) and II (2016) expeditions as well as Isopoda Kuril Kamchatka Trench the Russian-German SokhoBio (2015) campaign. The sampling area covered two potential geographical barriers Distribution (the Kuril Island archipelago and the Kuril-Kamchatka Trench), as well as three depth zones (bathyal, abyssal, Northwest Pacific hadal). We found significant differences in relative species abundance between abyssal and hadal depths. -

KAVANAGH1, GEORGE D. F. WILSON2 & ANNE MARIE POWER1 1 Department of Zoology, National University of Ireland, Galway, Ireland. [email protected] 2 Australian Museum, 6 College Street, Sydney, NSW 2010, Australia. [email protected] Abstract Two new species of Ischnomesidae, Haplomesus celticensis sp. nov. and Haplomesus hanseni sp. nov. are described from the southwest of Ireland and the Argentine Basin respectively. Both species lack the expression of pereopod VII, a characteristic that we argue is produced by progenesis, not neoteny as suggested by Brökeland & Brandt (2004). Haplomesus angustus Hansen, 1916 and Haplomesus tropicalis Menzies, 1962, also lack pereopod VII and are revised from the type material. The original description of Haplomesus angustus Hansen, 1916 describes the adult type specimen as a juvenile; the original description of Haplomesus tropicalis Menzies, 1962 fails to mention the lack of pereopod VII. Progenesis is discussed for the above species and within the family Ischnomesidae as a whole. Key words: Isopoda, Asellota, Ischnomesidae, Haplomesus, heterochrony, progenesis Introduction The Ischnomesidae is a family of marine benthic asellote isopods found mostly at bathyal and abyssal depths, with records from about 250–7000 m (Wolff 1962; Kussakin 1988). To date, 99 species have been described in five genera. The known diversity of this family, however, is increasing owing to recent reports of several new species (e.g. -

Cold seeps fluids provide an additional source of energy for various sulfide- and 27 hydrocarbon-harvesting bacteria, often in symbiosis with invertebrates, attracting a variety of other 28 organisms including crustaceans (e.g., Levin 2005; Vanreusel et al. 2009; Vrijenhoek 2013). The 29 percentage of crustaceans of all macrofaunal specimens is highly variable locally in modern seeps, from 30 0–>50% (Dando et al. 1991; Levin et al. -

Wilson1, J. Zhang3,15 and N. J. Bax2,16 Abstract Background: Our knowledge of the benthic fauna at lower bathyal to abyssal (LBA, > 2000 m) depths off Eastern Australia was very limited with only a few samples having been collected from these habitats over the last 150 years. In May–June 2017, the IN2017_V03 expedition of the RV Investigator sampled LBA benthic communities along the lower slope and abyss of Australia’s eastern margin from off mid-Tasmania (42°S) to the Coral Sea (23°S), with particular emphasis on describing and analysing patterns of biodiversity that occur within a newly declared network of offshore marine parks. Methods: The study design was to deploy a 4 m (metal) beam trawl and Brenke sled to collect samples on soft sediment substrata at the target seafloor depths of 2500 and 4000 m at every 1.5 degrees of latitude along the western boundary of the Tasman Sea from 42° to 23°S, traversing seven Australian Marine Parks. -
Crustacea, Malacostraca)*

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. -

Isopods are a highly diversified group of deep-sea fauna, with a wide variety of shapes which 14 must reflect a similar great variety of adaptations to the deep environments. The deep Mediterranean, 15 however, has a low diversity of isopods related to its oligotrophy, the thermal stability of deep-water 16 masses (~12.8 °C below 150 ˗ 200 m) and rather homogeneous geomorphology. -

In many cases isotopic variability can be influenced by the scale of sampling and biological characteristics including body size or sex. Sample size-corrected (SEAc) and Bayesian (SEAb) standard ellipse areas and generalised least squares (GLS) models were used to explore the spatial variability of δ13C and δ15N in Kiwa tyleri (decapod), Gigantopelta chessoia (peltospirid gastropod) and Vulcanolepas scotiaensis (stalked barnacle) collected from 3 hydrothermal vent field sites (E2, E9N and E9S) on the East Scotia Ridge (ESR), Southern Ocean. SEAb only revealed spatial differences in isotopic niche area in male K. tyleri. However, the parameters used to draw the SEAc, eccentricity (E) and angle of the major SEAc axis to the x-axis (θ), indicated spatial differences in the relationships between δ13C and δ15N in all 3 species. -
