  • Haustrum Scobina) Is an Endemic Direct- Developing Marine Mollusc Found in High Abundances at Rocky Intertidal Environments Across the Entirety of New Zealand
    Abstract: An effective investigation of the underlying ecological processes that shape genetic diversity and connectivity typically requires comparisons among phylogeographic studies of multiple species. Phylogeographic studies of New Zealand’s coastal marine benthos have historically relied on post hoc speculation rather than directed research questions to investigate ecological processes. There has also been a lack of studies on direct developing marine molluscs. Direct developers are expected to have a low potential for dispersal and thus show a pattern of genetic isolation by distance across their distributions. Recent research indicates that this assumption may frequently be violated by instances of long distance dispersal/translocation. The oyster borer (Haustrum scobina) is an endemic direct- developing marine mollusc found in high abundances at rocky intertidal environments across the entirety of New Zealand. This distribution and life history makes H. scobina an ideal target to study genetic connectivity in a species expected to show low realised dispersal and high population genetic structuring. This thesis research used 379 new DNA sequences from the mitochondrial gene cytochrome c oxidase subunit 1 (COI) to investigate the phylogeography of H. scobina across the southern North Island. In addition 16 new COI sequences were inadvertently sequenced from the morphologically similar congener Haustrum albomarginatum. Results from both species support the recently proposed division of H. scobina and H. albomarginatum as separate species. H. scobina populations show significant geographic structure and a lack of haplotype diversity across the south- eastern North Island concordant with results of another previous study of a direct developer. This finding suggests that ecological processes may be producing similar population genetic structures for direct developers generally.

  • Xenophoridae, Cypraeoidea, Mitriforms and Terebridae (Caenogastropoda)
    Taxonomic study on the molluscs collected in Marion-Dufresne expedition (MD55) to SE Brazil: Xenophoridae, Cypraeoidea, mitriforms and Terebridae (Caenogastropoda) Luiz Ricardo L. SIMONE Carlo M. CUNHA Museu de Zoologia da Universidade de São Paulo, caixa postal 42494, 04218-970 São Paulo, SP (Brazil) [email protected] [email protected] Simone L. R. L. & Cunha C. M. 2012. — Taxonomic study on the molluscs collected in Marion-Dufresne expedition (MD55) to SE Brazil: Xenophoridae, Cypraeoidea, mitriforms and Terebridae (Caenogastropoda). Zoosystema 34 (4): 745-781. http://dx.doi.org/10.5252/z2012n4a6 ABSTRACT The deep-water molluscs collected during the expedition MD55 off SE Brazil have been gradually studied in some previous papers. The present one is focused on samples belonging to caenogastropod taxa Xenophoridae Troschel, 1852, Cypraeoidea Rafinesque, 1815, mitriforms and Terebridae Mörch, 1852. Regarding the Xenophoridae, Onustus aquitanus n. sp. is a new species, collected off the littoral of Espírito Santo and Rio de Janeiro, Brazil, 430-637 m depth (continental slope). The main characters of the species include the small size (c. 20 mm), the proportionally wide shell, the white colour, the short peripheral flange, the oblique riblets weakly developed and a brown multispiral protoconch. This appears to be the smallest living species of the family, resembling in this aspect fossil species. In respect to the Cypraeoidea, the following results were obtained: family Cypraeidae Rafinesque, 1815: Erosaria acicularis (Gmelin, 1791) and Luria cinerea (Gmelin, 1791) had the deepest record, respectively 607-620 m and 295-940 m, although the samples were all dead, eroded shells. Family Lamellariidae d’Orbigny, 1841: a total of three lots were collected, provisionally identified as Lamellaria spp.

    Nearshore Marine Biodiversity of the Sunshine Coast, South-East Queensland: Inventory of molluscs, corals and fishes July 2010 Photo courtesy Ian Banks Baseline Survey Report to the Noosa Integrated Catchment Association, September 2010 Lyndon DeVantier, David Williamson and Richard Willan Executive Summary Nearshore reef-associated fauna were surveyed at 14 sites at seven locations on the Sunshine Coast in July 2010. The sites were located offshore from Noosa in the north to Caloundra in the south. The species composition and abundance of corals and fishes and ecological condition of the sites were recorded using standard methods of rapid ecological assessment. A comprehensive list of molluscs was compiled from personal observations, the published literature, verifiable unpublished reports, and photographs. Photographic records of other conspicuous macro-fauna, including turtles, sponges, echinoderms and crustaceans, were also made anecdotally. The results of the survey are briefly summarized below. 1. Totals of 105 species of reef-building corals, 222 species of fish and 835 species of molluscs were compiled. Thirty-nine genera of soft corals, sea fans, anemones and corallimorpharians were also recorded. An additional 17 reef- building coral species have been reported from the Sunshine Coast in previous publications and one additional species was identified from a photo collection. 2. Of the 835 mollusc species listed, 710 species could be assigned specific names. Some of those not assigned specific status are new to science, not yet formally described. 3. Almost 10 % (81 species) of the molluscan fauna are considered endemic to the broader bioregion, their known distribution ranges restricted to the temperate/tropical overlap section of the eastern Australian coast (Central Eastern Shelf Transition).
