  • Otago Submarine Canyons: Mapping and Macrobenthos
    Otago Submarine Canyons: Mapping and Macrobenthos Bryce A. Peebles A thesis submitted in partial fulfilment for the degree of Master of Science at the University of Otago December 2013 ii Abstract Submarine canyons are steep-sided “V’ or “U” shaped valleys that incise continental slopes worldwide. The geophysical and oceanographic features of submarine canyons can produce environmental conditions that cause benthic assemblages to be distinctive and productive compared to those of the adjacent slope; however the assemblages are potentially vulnerable to anthropogenic impacts, including bottom fishing. In order to help inform policy and management, submarine canyons need to be objectively defined topographically and their benthic assemblages characterised. A canyon network occurs off the Otago Peninsula, south-eastern New Zealand, but lack of detailed bathymetric data and adequate benthic sampling has limited study of the canyons. This thesis outlines a method of defining submarine canyon areas and examines epifaunal and infaunal assemblages of the Otago canyons and adjacent slope. Objective definition of the Otago canyon network in the GIS software GRASS along with the steps to use this methodology worldwide are described. Archival count data from 1966-74 on the epifauna are analysed using the PRIMER suite of programs to characterise epifaunal assemblages. Anomurans, polychaetes, asteroids and ascidians make up 70% of the epifaunal canyon assemblage. The epifaunal assemblage is clearly defined by water depth and recognisable from 380 m. Quantitative sampling of infauna in Saunders canyon, Papanui canyon and adjacent slope was carried out to examine infaunal community structure of the canyons and adjacent slope. Infaunal canyon assemblages are dominated by polychaetes, amphipods, ophiuroids, decapods and isopods in canyons, accounting for 75% of collected individuals.

  • Molluscs from the Miocene Pebas Formation of Peruvian and Colombian Amazonia
    Molluscs from the Miocene Pebas Formation of Peruvian and Colombian Amazonia F.P. Wesselingh, with contributions by L.C. Anderson & D. Kadolsky Wesselingh, F.P. Molluscs from the Miocene Pebas Formation of Peruvian and Colombian Amazonia. Scripta Geologica, 133: 19-290, 363 fi gs., 1 table, Leiden, November 2006. Frank P. Wesselingh, Nationaal Natuurhistorisch Museum, Postbus 9517, 2300 RA Leiden, The Nether- lands and Biology Department, University of Turku, Turku SF20014, Finland (wesselingh@naturalis. nnm.nl); Lauri C.

Kadolsky, 66, Heathhurst Road, Sanderstead, South Croydon, Surrey CR2 OBA, England ([email protected]). Key words – Mollusca, systematics, Pebas Formation, Miocene, western Amazonia. The mollusc fauna of the Miocene Pebas Formation of Peruvian and Colombian Amazonia contains at least 158 mollusc species, 73 of which are introduced as new; 13 are described in open nomenclature. Four genera are introduced (the cochliopid genera Feliconcha and Glabertryonia, and the corbulid genera Pachy- rotunda and Concentricavalva) and a nomen novum is introduced for one genus (Longosoma). A neotype is designated for Liosoma glabra Conrad, 1874a. The Pebas fauna is taxonomically dominated by two fami- lies, viz. the Cochliopidae (86 species; 54%) and Corbulidae (23 species; 15%). The fauna can be character- ised as aquatic (155 species; 98%), endemic (114 species; 72%) and extinct (only four species are extant). Many of the families represented by a few species in the Pebas fauna include important ecological groups, such as indicators of marine infl uence (e.g., Nassariidae, one species), terrestrial settings (e.g., Acavidae, one species) and stagnant to marginally agitated freshwaters (e.g., Planorbidae, four species).

J. Brook* A total of 358 species of molluscs (excluding pelagic species) is recorded here from coastal marine habitats around the northern Kermadec Islands. The fauna is dominated by species that are widely distributed in the tropical western and central Pacific Ocean. The majority of these are restricted to the tropics and subtropics, but some range south to temperate latitudes. Sixty-eight species, comprising 19% of the fauna, are thought to be endemic to the Kermadec Islands. That group includes several species that have an in situ fossil record extending back to the Pleistocene.

    THE EFFECT OF THE ECfOPARASITIC PYRAMIDELLID SNAIL, BOONEA IMPRESSA, ON THE GROWTH AND HEALTH OF OYSTERS, CRASSOSTREA VIRGINICA, UNDER FIELD CONDITIONS ELIZABETH A. WILSON,' ERIC N. POWELL,' AND SAMMY M. RAY· ABSTRACT BOfYMQ. (= Odostomia) impressa are contagiously distributed on oyster reefs so that some oysters are parasitized more than others. The parasite's mobility and the ability of oysters to recover from snail parasitism may be important in assessing the impact ofparasitism on oyster populations. Duringa 4-week exposure period in the field, B. impressa reduced American oyster, CrasS08trea virgillica, growth rate and increased the intensity ofinfection by the protozoan, Perki71/J'U8 (- Dermoeystidium) marillUB, but produced few changes in the oyster's biochemical composition because. although net productivity was reduced, the oysters retained a net positive energy balance (assimilation> respiration). During a 4-week recovery period, growth rate returned to normal (control) levels, but infection by P. marillUB continued to intensify in previously parasitized oysters kept B. impressa-free. Most changes in biochemical com­ position during recovery, including increased lipid and glycogen contents, could be attributed to the con­ tinuing increase in infection intensity of P. marillUB. Consequently, the temporal stability and size of snail patches. particularly as they regulate infection by P. marillUB, may be the most important factors influencing the impact of B. impressa on oyster reefs. Parasitism can be an important factor affecting the abundantly on oyster reefs from Massachusetts to population dynamics (Wickham 1986; Brown and the Gulf of Mexico, B. impressa has been reported Brown 1986; Kabat 1986) and health (Brockelman in numbers as high as 100 per oyster (Hopkins 1956).
