Abstract:

The Middle Cambrian lophotrochozoans Odontogriphus omalus and Wiwaxia corrugata have been interpreted as stem-group members of either the Mollusca, the Annelida, or a group containing Mollusca + Annelida. The case for each classification rests on the organisms' unusual mouthparts, whose two to three tooth-rows resemble both the molluscan radula and the jaws of certain annelid worms. Despite their potential significance, these mouthparts have not previously been described in detail. This study examined the feeding apparatuses of over 300 specimens from the 505-million-year-old Burgess Shale, many of which were studied for the first time. Rather than denticulate plates, each tooth row comprises a single axial tooth that is flanked on each side by eight to 16 separate shoehorn-shaped teeth. Tooth rows sat on a grooved basal tongue, and two large lobes flanked the apparatus. New observations—the shape, distribution and articulation of the individual teeth, and the mouthparts' mode of growth—are incompatible with an annelid interpretation, instead supporting a classification in Mollusca. The ancestral molluscan radula is best reconstructed as unipartite with a symmetrical medial tooth, and Odontogriphus and Wiwaxia as grazing deposit-feeders.

Abstract:

Definition and classification probably rank second only to marriage as a source of controversy, but it is not in that spirit in which I want to write; I only want to show that there may be more than one viewpoint about Mollusca. Problems of definition and classification are different. Workers may agree on the defintions of phyla and classes, yet disagree on their arrangement. Definition and classification each have two separate and distinct phases: the work itself on developing a concept; and the general acceptance of this concept. New ideas by their very nature go against prevailing opinion; it is not a new idea itself which is the critical feature as is its acceptance. Acceptance of definition and/or classification tends to be a passive process and most teachers are content to quote uncritically that which is in the latest textbook.

Abstract:

The “primitive,” “minor” or “lesser” classes of the Mollusca comprise four groups that are typically recognized at the class level in most classification schemes. These classes are: (1) the Aplacophora, (2) the Monoplacophora, (3) the Polyplacophora, and (4) the Scaphopoda. Members of these classes are bilaterally symmetrical and typically possess a ventral muscular foot and a dorsal epidermal tissue (the mantle) that secretes a calcareous covering. Between these two structures lie the viscera. The space that develops between the mantle and the foot of the mollusc is referred to as the mantle cavity. Into this cavity open the ducts from the excretory, alimentary, and reproductive systems; gills are also typically located in this space. The anterior end of these molluscs is marked by a muscular head in which most of the ganglia are concentrated. The mouth is situated ventrally and opens internally into the pharynx which contains, at its anterior end, the radula and its associated musculature and support structures. The intestinal tract is typically arranged in complex loops.

Abstract:

Achieving consensus on the definition of the Mollusca is fortunately not prerequisite to the exercise of taxonomic classification and phylogenetic analysis. Definitions emerge from analysis, and it is therefore germane to consider the ways in which analytic procedures and underlying assumptions may affect growth of knowledge of the Mollusca.

Abstract:

Like most classifications of molluscan shell microstructure published during the past 25 years (e.g., MacClintock, 1967; Kobayashi, 1964, 1971; Taylor, Kennedy and Hall, 1969, 1973; Grégoire, 1972a), the present one is based largely on Bøggild's (1930) monographic work, redefined from a modern perspective of combined light and scanning electron microscopy. However, this is the first attempt to integrate shell microstructure terminology for mollusks with that employed by students of bryozoan and brachiopod shell microstructure (e.g., Williams, 1968a,b, 1970, 1973; Williams and Wright, 1970; Armstrong 1968, 1969; Sandberg, 1971, 1977; Brunton, 1972; MacKinnon, 1974, 1977; MacKinnon and Williams, 1974; Iwata, 1981, 1982). An integration of nomenclatorial schemes is desirable for purposes of interphylum comparison, and is presently needed because there is considerable overlap and inconsistency in the application of microstructural terminology even within single molluscan classes. The present synthesis of shell microstructure nomenclature is possible primarily because of the extensive data base of invertebrate shell mineralogy, microstructure and especially ultrastructure published in more than 300 references in the past 15 years. To these data, the authors have contributed original information of shell mineralogy and microstructure for scores of Recent and fossil mollusks, brachiopods and bryozoans, with a clear emphasis on bivalved mollusks. Many inadequately described microstructure terms have been reanalyzed during the course of this study, either by examining species cited in the literature, or by using closely related species. Perhaps because they are better studied, but probably for other reasons as well, the diversity of molluscan shell microstructures is considerably greater than that of brachiopods and bryozoans combined (Carter, 1979). Consequently, most of the present nomenclature is based on mollusks, and only three of the major microstructural arrangements described in this guide (crossed bladed, semi-nacreous and semi-foliated) were known first in brachiopods or bryozoans and later recognized in molluscs.

Resumo: O Brasil aderiu ao "Tratado Antártico" em 1975, e desde 1982 mantém o "Programa Antártico Brasileiro. A partir de 1984 as pesquisas brasileiras se concentraram na Baía do Almirantado, na Ilha Rei George, onde se localiza a base do país. A Baía do Almirantado foi eleita uma "Área Antártica Especialmente Gerenciada" pelas Partes Consultivas do Tratado Antártico e trata-se de um local representativo do ecossistema costeiro antártico, principalmente em termos de distribuição e composição de espécies. Lá os pesquisadores tem estudado a fauna bentônica da região, entre eles os Mollusca, que são abundantes e importantes no estudo dos processos que determinam a estrutura e o funcionamento das comunidades bentônicas marinhas. Este estudo se focou na classe Bivalvia, provendo um novo material de referência para identificação destes animais, e mais especificamente daqueles da Baía do Almirantado, apresentando-se como um guia ilustrado, com descrições detalhadas das conchas dessas espécies. Além disso, dados de distribuição geográfica e batimétrica foram reunidos para uma análise dessa fauna, na tentativa de qualificar a importância da região das Ilhas Shetland do Sul como um local estratégico para estudos em biogeografia. Foram identificadas 39 espécies de 18 famílias distintas, e seus dados de biologia, distribuição batimétrica e geográfica reunidos. As famílias mais representativas foram Philobryidae, Nuculanidae e Lasaeidae, contabilizando 15 espécies. As regiões com mais espécies em comum com a área estudada foram o Estreito de Magalhães, Ilha Georgia do Sul, Mar de Weddell, Península Antártica e sul do Chile; regiões notáveis pela riqueza de Bivalvia. As famílias mais largamente distribuídas, encontradas neste estudo, foram LImidae e Carditidae; e as mais restritas foram Siliculidae e Nuculanidae. A espécie com maior distribuição foi Cyclocardia astartoides, e as mais restritas Ennucula georgiana e Mysella narchii. As espécies encontradas se concentram nas profundidades até 1000 m, com seu número caindo para menos da metade além disso. Apenas seis espécies ocorrendo além dos 2000 m: Yoldiella profundorum, Limopsis marionensis, Limopsis lilliei, Adacnarca nitens, Limatula pygmaea e Cyclocardia astartoides. Este estudo demonstram a região da Baía do Almirantado como abrigo de uma fauna de Bivalvia composta por espécies estritamente antárticas, e outras que ocorrem ao norte da Convergência Antártica; sendo assim uma região importante para o estudo da distribuição destes animais
Abstract: Brazil abided to the "Antarctic Treaty" in 1975, and since 1982 maintains the "Brazilian Antarctic Program". As from 1984 the Brazilian researches focused on Admiralty Bay, in King George Island, where the country?s Antarctic base is located. Admiralty Bay was elected a "Antarctic Especially Managed Area" by the Antarctic Treaty Consultative Parties and is a representative place for the Antarctic coastal ecosystem, especially in views of species distribution and composition. In there researchers have been studying the regional benthic fauna, amidst it the Mollusca, abundant and important animals for the study of determinant process in the structure and operation of the marine benthic community. The present study focused on the class Bivalvia, providing a new reference source for identification of the group, and specifically for those of Admiralty Bay, presented as an illustrated guide with detailed shell descriptions for all the species found. Furthermore, data on geographic and bathymetric distribution were gathered for an analysis of this fauna, in attempt to qualify the importance of the South Shetland Islands as a strategic place for studies on biogeography. Thirty-nine species, of 18 distinct families, were identified, and their biological, geographical and bathymetrical data gathered. The most representative families were Philobryidae, Nuculanidae and Lasaeidae, counting 15 species in sum. The geographic regions with more species in common with the studied area were Strait of Magellan, South Georgia Island, Weddell Sea, Antarctic Peninsula and Southern Chile; notable regions for Bivalvia richness. The families found with the largest geographic distribution were Limidae and Carditidae, and the most restricted ones were Siliculidae and Nuculanidae. The species with largest geographical distribution was Cyclocardia astartoides, while the most restricted were Ennucula georgiana and Mysella narchii. The species found in this study are concentrated in depths until 1000 m, beyond that their number shortens to less than half. Only six occur deeper than 2000 m: Yoldiella profundorum, Limopsis marionensis, Limopsis lilliei, Adacnarca nitens, Limatula pygmaea and Cyclocardia astaroides. The present study shows Admiralty Bay as shelter to a Bivalvia fauna with strictly Antarctic species and northern ones, common north to the Antarctic Convergence, thus being an important place for studying the distribution of these animals

Abstract:

The goal of this dissertation is to explore novel and non-traditional taxonomic characters that may be useful for mollusks, and combine them with radular and shell characters to carry out a taxonomic review of the genus Cribrarula (Cypraeidae). Shells in this genus have conspicuous dorsal spots, but like odler cowries, lack sculpture, spines, and other shell characters commonly used in gastropod taxonomy. For these reasons, cowrie shells are considered uninformative. The study of dorsal spots (DS) and related characters suggest that at least in this complex, the dorsal spots may represent a record of the mantle papillae. If the hypothesis is correct, then DS may provide information on the soft parts that previously was only available from the study of live or preserved specimens. Each species in the complex has a species-specific range of DS, marginal spots, and allied characters, thus suggesting that they may be useful in distinguishing species in the complex. The odontophore cartilage provides support for the radula and attachment for the muscles responsible for feeding. Although intimately connected to the radula and known since the 1800's, the taxonomic value of the odontophore has been overlooked. A study of odontophore variation in the family Cypraeidae proposes the structure as a novel taxonomic character, potentially applicable to most mollusks. The Cribrarula cribraria Linnaeus, 1758 complex is reviewed, and twelve species and six subspecies are recognized on the basis of multivariate analyses of shell characters, the radula, odontophore, and geographic distribution. The shell, radula, odontophore and distributional maps are illustrated for each taxon. The nominal species, cribraria, ranges from East Africa to the Central Pacific, and several populations are distinctive enough to be recognized as subspecies. The other eleven species are restricted to narrower ranges along the periphery of the distribution of cribraria. During the review of Cribrarula, a new species from New South Wales was described as C. gravida Moretzsohn, 2002.

Abstract:

The aim of this study is to assess the biological accumulation of pesticide residues in aquatic organisms in Sai Gon - Dong Nai (SG-DN) estuary. Fish and mollusks were collected directly at the Soai Rap and Long Tau estuary of the SG-DN river system, washed and separated for taking the tissue. The organochlorine compounds from the tissue were then extracted and analyzed by gas chromatography system. The results showed that, the concentration of OCPs in Tegillarca granosa, Meretrix lyrata, Margaritifera auricularia and Bostrychus sinensis varied from 6.4 to 59.9 μg/kg, 7.2 to 322 μg/kg, 4.5 to 62.1 μg/kg and 2.9 to 114.3 μg/kg fresh weight, respectively. In general, molluscs species that accumulate more heptachlor, aldrin, endrin or dieldrin tend to accumulate less DDT (dichlorodiphenyltrichloroethane). Endosulfan was the most commonly found in three bivalve mollusks while DDTs (1.5–75.2 μg/kg, averaging 8.7 μg/kg weight) was the most popular OCPs in the fish (Bostrychus sinensis) samples. In DDT group, the p,p’-DDT metabolite accounted for the largest percentage, reaching 50% of total DDTs. In HCH (Hexachlorocyclohexane) group, β-HCH isomer was predominant in almost samples.

Abstract:

D’un point de vue géographique, la lagune de Venise n’a que peu en commun avec les baies principales de la Bretagne septentrionale, si ce n’est son ouverture sur la mer. Les deux réalités étudiées ont pourtant en commun leur soumission à l’action des marées qui a poussé les populations littorales à développer des savoirs et des techniques de pêche traditionnelles d’une très grande richesse et qu’ils ont su faire évoluer au cours du temps pour mieux les adapter aux caractéristiques du milieu.Les différentes formes de récolte et de pêche, l’élevage des moules en particulier, ont entraîné une domestication et une anthropisation de ces zones. En Bretagne, tout comme à Venise, la valorisation de la moule en tant que ressource alimentaire et économique est assez tardive.Que ce soit dans les sources bibliographiques ou durant l’enquête réalisée sur le terrain, notre recherche nous a permis de repérer des allusions fréquentes à la toxicité présumée de ce mollusque, à Venise appelé « peòcio » c’est-à-dire « pou » et considéré non comestible. Quels mécanismes ont métamorphosé la moule en un aliment aujourd’hui apprécié et recherché ? Et comment des zones, autrefois très pauvres se sont transformées, en des lieux renommés pour la production de moules ? C’est pour répondre à ces questions que nous avons entrepris la reconstruction de l’histoire de la mytiliculture
From a geographic perspective, the Venice Lagoon has almost nothing in common with the main northern bays of “Bretagne”; simply, both open on the sea. Therefore, the two studied realities have to share their submission to the action of tides that have pushed the coastal communities to develop fishing knowledge and techniques. They were able to evolve over time to better suit the characteristics of the environment. The different forms of harvesting and fishing, mussel farming in particular, led to domestication and human impacts in these areas. In “Bretagne”, as in Venice, is rather late the development of mussels as food and as economic resource.Whether in the literature sources or during the survey in the field, our research has led us to identify frequent allusions to the alleged toxicity of this mollusk in Venice called “peòcio” that mean “cootie” and considered inedible. What mechanisms have metamorphosed mussels into a regarded and sought food today? And how formerly very poor areas are transformed into places renowned for the production of mussels? It is to answer these questions that we undertook the reconstruction of the history of the mussel
Da un punto di vista geografico la laguna di Venezia ha poco in comune con la Bretagna settentrionale se non il suo sbocco sul mare. Di conseguenza le due realtà condividono la dipendenza dall’azione delle maree, le quali hanno spinto le popolazioni litoranee a sviluppare dei saperi e delle particolari tecniche di pesca adattate alle caratteristiche dell’ambiente.Nel corso della nostra ricerca abbiamo incontrato delle frequenti allusioni alla presunta tossicità del mitilo, a Venezia chiamato “peòcio”, cioè pidocchio. Infatti a Venezia, come in Bretagna, la valorizzazione dei mitili quale risorsa alimentare ed economica è un fenomeno tardivo. Quali meccanismi hanno trasformato i mitili in un alimento che è oggi apprezzato e ricercato? E in che modo delle zone un tempo molto povere si sono trasformate in località rinomate per la produzione di questi molluschi? Per rispondere a queste domande abbiamo ricostruito la storia della mitilicoltura

Abstract:

The taxonomy and biogeography of the southern African pheasant shell fauna are poorly known. Thirty–one nominal taxa referable to Phasianelloidea have been described or recorded in this region, but no systematic revision of these has ever been undertaken. Morphological evidence suggests that 16 taxa represent valid species, 13 are synonyms and two represent incorrect identifications. DNA sequence data from mitochondrial COI and 16S markers are used to assess the validity of the described nominal southern African Tricolia species. Phylogenetic analyses recovered seven distinct clades. Tricolia adusta, T. elongata, T. formosa, T. kochii, T. saxatilis and T. neritina were recovered as distinct species. Tricolia africana and T. capensis are genetically indistinguishable. However, morphological characters of the shell are clearly diagnosable. This could be due to incomplete sorting (ancestral polymorphism) reflecting recent speciation with rapid morphological and ecological divergence co–incident with geographical separation. Similarly, there is little genetic differentiation between T. bicarinata, T. insignis and T. kraussi. In this case the similarity is also supported by morphological data as the three species are conchologically close with intergrading shell characters, and might even be one species exhibiting ecogeographic variation in shell form. Monophyly of the southern African Tricolia species is not supported as well as the relationship between these and the European Tricolia pullus. In the last chapter a molecular phylogeny based on sequence data from mtDNA (COI and 16S), nuclear (18S and 28S) and the combined data (COI, 16S, 18S and 28S) is presented for the Phasianelloidea. Bayesian inference analyses performed on the combined data support the monophyly of Tricolia sensu stricto, Eulithidium and Phasianella. Tricolia sensu lato is not monophyletic, as its southern Australian and Indo–West Pacific species do not cluster with its southern African and Eastern Atlantic representatives. The position of Hiloa and Gabrielona within the Phasianelloidea is unresolved. Phylogenetic reconstructions using bayesian inference support monophyly of the Phasianelloidea.

Abstract:

Abstract Aquaculture species diversity is much greater than that of farmed terrestrial species and they occupy more diverse positions within the network of life. The species that form the network of life are classified by the discipline of taxonomy founded by Carl von Linné, who introduced the unambiguous binomial nomenclature of species. Taxonomic classification of species within higher-level categories in the network of life is based on their phylogenetic (ancestral) relationships that can be revealed by comparing their genomes. Many aquatic animals are used for aquaculture, but three taxa dominate: fish (class of subphylum vertebrates), molluscs (a phylum), and crustaceans (subphylum of phylum arthropods). Although many aquatic species are being cultured, only a handful of fish, mollusc, and crustacean species are produced at high quantity and account for most of global seafood production. Freshwater fish, in particular carp, contribute most to aquaculture yields. A single marine species of crustaceans (Western whiteleg shrimp) accounts for more than half of crustacean aquaculture, the remainder being contributed mostly by freshwater crayfish and prawns. Molluscs are farmed almost exclusively by mariculture with cupped oysters such as the Pacific (Japanese) cupped oyster dominating mollusc aquaculture for production of seafood. Aquaculture production of marine seaweed has tripled since the turn of the millennium but its exact contribution to seafood production is difficult to estimate because of alternative uses.

Abstract:

Dr Allen Sturge spelled out some of the problems facing researchers who worked on the British Palaeolithic in his first Presidential Address to the Prehistoric Society of East Anglia. For the Drift period, the main task was ‘to ascertain the relative ages of the humanly-worked stones, and the number of the periods concerned’.1 In 1908, when Sturge made this suggestion, he was troubled by suspicions that the French divisions—Chellean, Acheulian, and Mousterian—were too broad to encompass the variety of British tools. He called on the younger school of geologists to help solve the dificulty. A few elderly Wgures, familiar from previous chapters, would accompany Sturge’s younger school of geologists as they worked on various sequences that could give a date to the stone tools of Britain. James Geikie published The Antiquity of Man in Europe in 1914, still defending his sequence of interglacials. 2 Harmer was inspired to take up the glacial researches of his old friend Wood as the twentieth century dawned. The refiection left by the Glacial epoch in East Anglia also led the young geologist Percy Boswell (1886–1960) to consider the connections between boulder clays and Palaeolithic industries. Dawkins continued to promote his classification of Quaternary mammals and to attack Geikie’s views, but two newcomers took a different approach to the palaeontological sequence. Martin A. C. Hinton and Alfred Santer Kennard used the bones of smaller mammals and the shells of molluscs to reconstruct the geological history of the Thames Valley. They maintained the traditional antagonism of palaeontologists towards the theories of glacial geologists by suggesting controversial links between the river drifts and the glacial sequence.3 Meanwhile, Warren, the eolith sceptic, developed his own opinions about the British Palaeolithic sequence and its place in geological time as he worked on Palaeolithic sites around Essex. Several different answers to Sturge’s question about the relative ages of stone tools would be extracted with the help of these sequences of glacial deposits, bones and shells, and river sediments.
