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. -

Department of Zoology and Aquaculture, Acharya Darwin Ch. and P Padmavathi Nagarjuna University Nagarjuna Nagar, Abstract Andhra Pradesh, India Among the various groups represented in the macrobenthic fauna of the Bay of Bengal at Prakasam P Padmavathi district, Andhra Pradesh, India, molluscs were the dominant group. Molluscs were exploited for Department of Zoology and industrial, edible and ornamental purposes and their extensive use has been reported way back from time Aquaculture, Acharya immemorial. Hence the present study was focused to investigate the diversity of Molluscan fauna along Nagarjuna University the Paleru and Moosy backwaters of Prakasam district during 2016-17 as these backwaters are not so far Nagarjuna Nagar, explored for malacofauna. A total of 23 species of molluscs (16 species of gastropods belonging to 12 Andhra Pradesh, India families and 7 species of bivalves representing 5 families) have been reported in the present study. Among these, gastropods such as Umbonium vestiarium, Telescopium telescopium and Pirenella cingulata, and bivalves like Crassostrea madrasensis and Meretrix meretrix are found to be the most dominant species in these backwaters. Keywords: Malacofauna, diversity, gastropods, bivalves, backwaters 1. Introduction Molluscans are the second largest phylum next to Arthropoda with estimates of 80,000- 100,000 described species [1]. These animals are soft bodied and are extremely diversified in shape and colour. -

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. -

Av. Benavides 5400, Surco. P.O. Box 18-131. Lima, Perú. Abstract: Peru is an ecologically diverse country, with 84 life zones in the Holdridge system and 18 ecological regions (including two marine). 1910 molluscan species have been recorded. The highest number corresponds to the sea: 570 gastropods, 370 bivalves, 36 cephalopods, 34 polyplacoforans, 3 monoplacophorans, 3 scaphopods and 2 aplacophorans (total 1018 species). The most diverse families are Veneridae (57spp.), Muricidae (47spp.), Collumbellidae (40 spp.) and Tellinidae (37 spp.). Biogeographically, 56 % of marine species are Panamic, 11 % Peruvian and the rest occurs in both provinces; 73 marine species are endemic to Peru. Land molluscs include 763 species, 2.54 % of the global estimate and 38 % of the South American esti- mate. The most biodiverse families are Bulimulidae with 424 spp., Clausiliidae with 75 spp. and Systrophiidae with 55 spp. In contrast, only 129 freshwater species have been reported, 35 endemics (mainly hydrobiids with 14 spp. The paper includes an overview of biogeography, ecology, use, history of research efforts and conser- vation; as well as indication of areas and species that are in greater need of study. -

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. -
