Signed: Date: 12/09/2014 i Determination of the Abundance and Population Structure of Buccinum undatum in North Wales Zara Turtle Abstract A mark-recapture study and fisheries data analysis for the common whelk, Buccinum undatum, was undertaken for catches on a commercial fishing vessel operating from The fishing location, north Wales, from June-July 2014. Laboratory experiments were conducted on B.undatum to investigate tag retention rates and behavioural responses after being exposed to a number of treatments. Thick rubber bands were found to have a 100 % tag retention rate after four months. Riddling, tagging and air exposure do not affect the behavioural responses of B.undatum. The mark-recapture study was used to estimate population size and movement. 4007 whelks were tagged with thick rubber bands over three tagging events. -
Preliminary Appraisal of Imposex in Areas Under the Influence of Southern Brazilian Harbors

FILLMANN2* 1Laboratório de Zoobentos, Instituto de Ciências do Mar, LABOMAR/UFC, Av. da Abolição, 3207, Bairro Meireles, CEP 60165-081, Fortaleza, CE, Brasil 2Fundação Universidade Federal do Rio Grande, C.P. 474, CEP 96201-900, Rio Grande, RS, Brasil (Received November 1, 2006; Accepted January 10, 2007) ABSTRACT Imposex in gastropod mollusks is an efficient and low-cost biomarker for pollution by organotin compounds. Such substances are typically found in areas with an intense flux of vessels, such as marinas and harbors. This study preliminarily evaluated the occurrence of imposex in Stramonita haemastoma (Linnaeus, 1758) populations along the areas under the influence of the main harbors from southern Brazil (Paranaguá, PR; São Francisco do Sul, SC; Itajaí, SC; and Rio Grande, RS). Although no chemical analyses were performed so far to confirm the presence of organotins, the occurrence of imposex strongly suggests a contamination by these compounds in the studied areas and it is likely that the closest from the harbors (as the main sources) the more contaminated the environment. However, due to the limitations of S. haemastoma, it is important to assess the response of alternative species adapted to mesohaline environments and non-consolidated substrates, in order to make up for the lack of indicator species for some areas such as Patos Lagoon and Itajaí-Açu estuaries. Key words: imposex, Stramonita haemastoma, organotin, estuary, southern Brazil. -

Nittionat Museum of Nbturat History, Smithsonian institution. PVbshington, DC 2a560 USA Abstract: Bathybuccinum (Ovulatibuccinunz) clarki new species, is described from bathyal depths off the central Aleutian Islands, This new species is provisienally assigned to the genus Batdybuccinum primarily en the basis of its distinctive triangular operculum with terminal nuclcus, and large osphradium, which are rare features in Buccininae. Conchologi- cally, the new species most closely resembres Buccinum (EpistobuccinumJ epistomium Dall, 1907, which, however, has a typical buccinid eperculum that is large, oval, with a subcentral nucleus. Key words: Neogastropoda, Buccinidae, Batlu,buccinum, North Pacific, new species. Introduction Neogastropods of the family Buccinidae comprise a diverse and abundant component of the subtidal to abyssal fauna of carnivores and scavengers, especially in temperate and polar regions. The rank and composition of this taxon has been subject to widely varying interpretations (e.g. Boss, 1982; Ponder & Waren, 1988; Vaught, 1989), and is still far from resolved. Habe & Sato (1972) divided the northern Pacific Buccinidae into six subfamilies, including the nominotypical subfamily Buccininae. Golikov (1980) mono- graphed the Buccininae, subdividing it into 3 genera, 3 subgenera and 88 species. Tiba and Kosuge (1984) reviewed and illustrated 49 North Pacific species of the genus Buccinum. Most recently, Golikov & Sirenko (1988) proposed a new classification of the subfamily Buccininae, recognizing 5 genera, 23 subgenera and I08 species, all from the boreal region. -

Rapa whelks eat bivalve molluscs. They are generalist predators; that is, they do not require a particular kind of bivalve. They will eat whatever bivalves are avail- able to them. In the lower Chesapeake Bay the poten- tial menu for rapa whelks includes hard clams (Mercenaria mercenaria, Figure 2), mussels (Mytilus Figure 2: Two adult hard clams.

We studied 18 species of Buccinidae that belong to eight different genera and inhabit the China coastal seas. We analyzed the patterns of divergence between an outgroup and basal ingroup taxa, the monophyly of the genus Neptunea, and the position of one unnamed species within the Buccinidae. A phylogenetic tree (neighbor-joining (NJ) method) was reconstructed based on the sequences of 18S rRNA, 28S rRNA and COI, with Rapana venosa as outgroup. The NJ tree indicated that the 18 species could be divided into five groups. The genus Buccinum was monophyletic, whereas Neptunea was shown to be paraphyletic since it included Siphonalia subdilatata and Neptunea sp., a new species. -
