▼ Marine bivalves are globally recognized as ecologically and commercially valuable species and, for over a century, researchers have been studying their feeding, digestion and other related physiological processes. These studies have shown that marine bivalves have complex feeding and particle processing behaviors to maximize growth in dynamic environmental conditions. Additionally, these studies have provided insights into the ecological roles that these animals can play in coastal waters. Suspension-feeding bivalves are commonly regarded as providing key ecosystem services through their feeding activities that improve water quality and clarity. However, marine bivalves are currently under threat from a variety of anthropogenic effects and there is concern about their future health under these new stresses. Here I examined several unexplored aspects of adult and larval bivalve feeding physiology in an attempt to better understand environmental effects on their feeding activity and ecosystem services. In Chapter 2, my co-authors and I examined the ecological feeding physiology of native Olympia oysters Ostrea lurida by determining their feeding and particle processing behavior in response to the effects of temperature, salinity, and total particulate matter. We examined and compared these processes to those of the non-native yet dominant commercial oyster species, the Pacific oyster Crassostrea gigas. From these studies, we describe the first modern detailed feeding behavior of O. lurida. We found that, although markedly different in laboratory studies, in situ feeding rates were similar between these species seasonally. We concluded that bivalve filtration services are likely to be greater with the emergence of C. gigas as the now dominant species in many PNW estuaries and seasonally much greater than the services historically contributed by O. lurida. In Chapters 3, my co-authors and I examined the particle processing behavior of bivalve larvae. This study was novel in that it utilized methods of our own design to examine the rarely evaluated post-oral particle processing behavior of larvae that historically has been difficult to measure. Additionally, it represented the first attempt at modeling larval guts as chemical reactors to provide insights into their digestive strategies. In Chapter 4, we again applied these novel techniques to evaluate the effects of ocean acidification on ingestion rates and particle processing of larvae of the California mussel Mytilus californianus. These data were applied to a simple larval energy budget to understand how impacts of ocean acidification on initial larval development may affect their subsequent development rates. The outcomes of these experiments provide useful information on feeding and particle processing activities of the adult and larval life stages of marine bivalves and the effects of environmental factors, such as ocean acidification.

▼ Resumo: Os Glossoidea Gray, 1847 (1840) compreendem uma superfamília de bivalves relativamente pequenos e taxonomicamente controverso. Tradicionalmente, baseados na conquiliologia e anatomia, eles vêm sendo subdivididos em três táxons, os Glossidae Gray, 1847, Vesicomyidae Dall & Simpson, 1901 e Kelliellidae Fischer, 1887. Em relação aos Kelliellidae, a maioria das espécies podem ser caracterizadas como sendo bivalves muito pequenos, frequentemente menores que 15 mm em comprimento de concha, ocorrendo em águas frias e profundas. Uma nova "Kelliella" sp., encontrada em águas rasas, é aqui descrita, baseada em um material coletado na Bacia de Campos, uma área intensamente explorada pela riqueza de petróleo na costa brasileira, localizada no Oceano Atlântico sudoeste, durante dois Projetos: "HABITATS" e "AMBES". Aqui, a descrição dessa nova espécie do gênero "Kelliella" é baseada em observações detalhadas da concha e da parte mole obtidas através de estereomicroscópio, imagens de MEV e cortes histológicos. Essa possível nova espécie é pequena (até 2,3 mm em comprimento), com valvas arredondadas, ligeiramente inequilateral e uma lúnula bem demarcada e ampla. Superfície externa com linhas de crescimento microscópicas; micro pústulas presentes na dissoconcha, próximo ao limite com a prodissoconcha. Placa da charneira com três dentes cardinais em cada valva. Sobre a anatomia, é descrita com duas aberturas paliais; glândulas de muco margeando toda a abertura pediosa-inalante, também presente na margem do manto dorso-posterior. Ctenídeo completo; palpos labiais muito pequenos. Pé bem desenvolvido com formato de foice com uma glândula de bisso presente. Provavelmente dióicos. "Kelliella" sp. é comparada com outras espécies de "Kelliella" que ocorrem nos oceanos Atlântico, Antártico, Pacifico e Ìndico, provando ser uma possível espécie nova registrada para a costa Brasileira; Abstract: The Glossoidea Gray, 1847 (1840) comprises a relatively small but taxonomically controversial superfamily of bivalve molluscs. Traditionally, based on conchological and anatomical grounds, they have being subdivided in three taxa, the Glossidae Gray, 1847, Vesicomyidae Dall & Simpson, 1901 and Kelliellidae Fischer, 1887. Regarding the Kelliellidae, most species can be characterized as being very small bivalves, often less than 15 mm in shell length, occurring in cold and deep waters. A new "Kelliella", discovered in the shallow waters, is here described, based on material collected in Campos Basin, an intense explored oil-rich area of the Brazilian coast, placed in the southwestern Atlantic Ocean, during two research Projects: "HABITATS" and "AMBES". Herein, the description of this new "Kelliella" is based on detailed observations of the shell and the soft parts through stereomicroscope, SEM images and histological sections. This possible new species is minute (up to 2.3 mm in length), valves rounded in outline, slightly inequilateral and well demarcated, wide lunule.

▼ Laternula elliptica are large bivalves found in high densities in soft sediments in coastal regions of the Southern Ocean. L. elliptica form an important part of the ecosystem, due to significant sediment stabilisation and deposition. Despite the important role L. elliptica play in their environment, little is known about how projected ocean change will impact future populations of this species. Invertebrate larvae are considerably more sensitive to environmental stressors than juveniles and adults, and increases in mortality and minor reductions in dispersal could significantly reduce future population sizes. In a rapidly changing climate, some of the greatest changes are expected at high latitudes. The greatest rates of warming of surface waters are occurring in the Southern Ocean. Additionally, undersaturation of aragonite due to ocean acidification is expected to affect these waters within decades. Calcifying organisms such as molluscs may be particularly sensitive to reduced pH and saturation states associated with ocean acidification. However, information on larval responses to these stressors in Antarctic species is limited. The larvae of L. elliptica are large and lecithotrophic. Maternally provided energy reserves sustain development until the completion of metamorphosis. While large reserves may support long development times and extended encapsulation, they are finite and cannot be replenished. Any stress during larval development could increase metabolic costs and deplete reserves, preventing metamorphosis. These stressors may also impact the calcification process and shell structures, resulting in weaker larvae at settlement that are more vulnerable to injury. Small reductions in larval survival could limit recruitment and population growth may decline. Various responses to ocean acidification (OA) and warming were studied in the larvae of L. elliptica. Larvae were raised under control pH and temperatures (~8.00 and - 1.7°C, respectively) and conditions representing projections for the Antarctic by the end of the century and 2300 (pH 7.80, 7.65 and -0.5, +0.5 and +1.5°C), both individually and in combination. The effect of these stressors on fertilisation rates, development timing and rates of abnormalities at various life stages were examined. Furthermore, SEM analysis determined the impacts of OA and warming on larval shell growth and morphology. Respiration rates and lipid reserves in developing larvae were also determined. Information on OA and temperature responses in Antarctic larvae is limited, and this is the first study on the effects of these stressors in Antarctic bivalves. Elevated temperatures largely improved development, increased early fertilisation rates, and accelerated development through all larval stages and larvae reached competency 5 d ahead of larvae at the control temperature. This would allow for faster settlement, significantly reducing time spent in more vulnerable development stages. Elevated temperatures also improved calcification in later D-stage larvae increasing shell… Advisors/Committee Members: Ken, Ryan, Vonda, Cummings.

▼ Resumo: A quantidade de espécies envolvidas, a amplitude geográfica e a freqüência de ocorrência das invasões biológicas não conhecem precedentes. Atualmente as invasões são consideradas um processo composto de múltiplos estágios, dinâmico no espaço e no tempo. As populações invasoras podem estacionar em determinados estágios e até regredir a estágios anteriores antes de atingir a fase de clímax. As invasões são consideradas uma das grandes causas da extinção de espécies no planeta, desta forma, a compreensão dos mecanismos e fatores que influenciam o sucesso das invasões e o entendimento de seus efeitos em comunidades nativas é fundamental. O objeto de estudo do presente trabalho é o bivalve invasor Isognomon bicolor em costões rochosos do sudeste do Brasil. No capítulo I, padrões de distribuição e dominância de populações localizadas no litoral norte de São Paulo foram documentados. A situação atual da invasão de I. bicolor foi avaliada frente às populações de organismos nativos da área. No capítulo II, padrões de variabilidade e estruturação genética de populações de I. bicolor no litoral sudeste foram descritos e comparados com aqueles para populações do bivalve nativo Brachidontes solisianus. A combinação dessas duas abordagens permitiu uma maior compreensão do processo de invasão de I. bicolor e das conseqüências dessa invasão sobre as espécies nativas. Atualmente I. bicolor apresenta-se amplamente distribuído no litoral norte de São Paulo, entretanto, ao contrário de estudos anteriores, suas populações apresentam baixas porcentagens de cobertura nos costões onde ocorre. Tal fato deve-se a um evento de mortaliade em massa pelo qual a espécie passou recentemente. A alta variabilidade e baixa estruturação genética observada, semelhante à encontrada para o bivalve nativo B. solisianus, são indícios de um processo de invasão costituido por múltiplos episódios de introdução e da grande capacidade de dispersão do invasor. Esses resultados são preocupantes pois sugerem que as populações de I. bicolor estão relativamente estáveis e conectadas entre si, tornando sua exitinção na costa sudeste do Brasil improvável, mesmo após a ocorrência do evento de mortalidade em massa; Abstract: The species number, geographic scale and frequency of biological invasions are unparalleled. Currently, invasions are considered as a several stages process, dynamic in space and time. The invasive populations can remain at some stage or return to earlier stages before reaching the invasion climax. Invasions are considered one of the major causes of species extinction on the planet and thus. Understanding mechanisms and factors that influence invasion success and its effects on native communities is of primary imporatance. The present work studied the invasive Isognomon bicolor populations along the southeastern coast of Brazil. In Chapter I, the distribution and the dominance patterns of I. bicolor were documented along the northern coast of São Paulo. The population attributes of the invasive species I. bicolor were evaluated and compared… Advisors/Committee Members: Duarte, Luiz Francisco Lembo, 1951- (advisor), Solferini, Vera Nisaka, 1957- (advisor), Dias, Gustavo Muniz (committee member), Passos, Flávio Dias (committee member).

▼ Resumo: A conservação da biodiversidade marinha e o pouco conhecimento sobre a ecologia das espécies que habitam regiões mais profundas são temas atuais e amplamente discutidos. Com o objetivo geral de conhecer as espécies e a ecologia dos organismos marinhos bentônicos da Bacia de Campos - RJ, foi implantado o programa HABITATS- "Avaliação da Heterogeneidade Ambiental da Bacia de Campos". Apoiado pela Petrobras S.A./CENPES, o programa HABITATS foi realizado no período de fevereiro/2009 a julho/2009 e foi composto por nove transectos perpendiculares a linha da costa, localizados principalmente entre a Plataforma e o Talude Continental, totalizando 149 estações de coleta em faixas batimétricas que variaram de 25 a 3.000 metros de profundidade. O presente trabalho se baseia em espécimes obtidos a partir desse programa e tem como objetivos principais, o registro de duas famílias de bivalves (Cyamiidae e Spheniopsidae) para o Brasil, além da análise taxonômica e da descrição de três novas espécies de microbivalves. Após cerca de dois anos de triagens mais de 5.000 espécimes de bivalves provindos da Plataforma Continental foram analisados. Desse total foram identificadas 180 espécies, agrupadas em 47 famílias. Nesse trabalho foram descritas três novas espécies de microbivalves: Cyamiocardium sp. n. pertencente à família Cyamiidae; Grippina sp. n. e Spheniopsis sp. n. pertencentes à família Spheniopsidae. Ambas, devido ao tamanho diminuto (1,75 - 4,5 mm de comprimento), não puderam ter a sua anatomia descrita apenas por técnicas manuais de dissecção, sendo submetidas então a um processo de descalcificação e posteriormente a microscopia eletrônica de varredura e a histologia. Foram analisados 356 indivíduos de Cyamiocardium sp. n. sendo 25 destes com parte mole e coletados em uma faixa de 26-75m de profundidade. Para as espécies de Spheniopsidae, foram analisados 58 indivíduos de Grippina sp. n. sendo 20 com parte mole e coletados entre 21-53 m de profundidade e 189 indivíduos de Spheniopsis sp. n. sendo 2 com parte mole e coletados entre 17-148 m de profundidade. Para a família Cyamiidae cujas espécies eram até então distribuídas somente em águas australianas, neozelandesas, antárticas, subantárticas e magelânicas, o presente trabalho ampliou sua distribuição, fazendo o primeiro registro da família para águas brasileiras, além de descrever uma nova espécie. Já para a família Spheniopsidae além de um novo registro e da descrição de duas novas espécies, foi realizada a primeira descrição anatômica do grupo além de uma discussão sobre sua posição filogenética dentre os Anomalodesmata; Abstract: The conservation of marine biodiversity and little knowledge about the ecology of the species inhabiting deeper regions are current topics widely discussed.

▼ O estuário do rio Formoso localiza-se no litoral sul do estado de Pernambuco (8º 39 - 8º 42 S e 35º 10 35º 05 W) e está inserido em uma área de proteção ambiental, denominada APA de Guadalupe. Este ecossistema desempenha um importante papel socioeconômico para a comunidade local, além de possuir uma grande diversidade ecológica. Os impactos produzidos pelos despejos de efluentes hospitalares e domésticos, aumento do trafego de embarcações motorizadas, carreamento de agrotóxicos de plantações das proximidades e uso destes para a pesca predatória, provocam um acentuado desequilíbrio no estuário, refletindo diretamente na população local, pela introdução de metais-traço nas áreas costeira e estuarina. Baseado nestas prerrogativas, o presente estudo visou a determinação das concentrações de metais-traço (zinco, selênio, arsênio, alumínio, ferro, manganês, chumbo e cromo) no sedimento superficial e em duas espécies de moluscos filtradores (Crassostrea rhizophorae e Mytella charruana), objetivando basicamente avaliar o grau de contaminação do estuário e fornecer indicadores para o estabelecimento de um futuro monitoramento ambiental da área. Amostras de sedimentos superficiais foram coletadas em 04 estações ao longo do estuário, durante os períodos seco e chuvoso do ano de 2009 nas margens direita e esquerda do estuário do rio Formoso. A profundidade do material coletado esteve compreendida entre 0 e 10 cm, onde as amostras foram colhidas durante as baixa-mares. Amostras do material biológico foram coletadas em bancos naturais do estuário localizados próximos à estação 2. Os parâmetros hidrológicos foram coletados nas mesmas estações do sedimento, na parte mais profunda da área. Os resultados obtidos indicaram elevadas concentrações de zinco, arsênio, ferro, manganês, chumbo e cromo nos sedimentos e arsênio, ferro e manganês nos moluscos bivalves. Para análise e quantificação dos metais nos sedimentos e moluscos, foram realizadas digestões ácidas próprias para cada matriz e utilizado o Espectrômetro de Emissão Ótica em Plasma Indutivamente Acoplado (ICP-OES). Os dados produzidos indicaram contaminação das matrizes utilizadas na pesquisa, onde os resultados obtidos foram comparados aos valores de referência das agências ambientais nacionais e internacionais Advisors/Committee Members: José de Macêdo, Silvio (advisor).

▼ 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".

▼ This dissertation investigated the ‘disco’ clam Ctenoides ales (Limidae), which is the only bivalve to have a behaviorally-mediated flashing display. Topics covered include (i) mechanisms, ultrastructure and movement that produce the flashing, (ii) the fitness value (function) of the flashing, (iii) the clams’ sensory abilities and vision, and (iv) the clams’ ecology, distribution and habitat. The flashing occurs on the clams’ mantle lip. Electron microscopy revealed two distinct tissue sides; one highly scattering side that contains dense aggregations of spheres composed of silica (white), and one highly absorbing side that does not (red). High-speed video confirmed that the two sides alternate rapidly, creating the appearance of flashing. Optical modeling suggested that the sphere’s diameter is nearly optimal for scattering light, especially at shorter wavelengths, which predominate in the ocean. This simple mechanism produces a striking optical effect. Three potential hypotheses for the fitness value of the flashing were investigated; conspecific attraction, prey luring, and/or predator deterrence. The lack of movement toward other C. ales when given visual cues in behavioral trials, as well as the clams’ inability to resolve flashing in other C. ales suggested conspecific attraction was not the function of the flashing. The lack of significant differences in prey abundance in experiments testing flashing versus non-flashing clams suggested prey luring was also not the function of the flashing. Predator deterrence is considered a possible function of the flashing due to (i) sulfur presence in the clam’s tissues, (ii) behavioral responses by predators during feeding trials as well as tissue preferences that suggest potential distastefulness, and (iii) the clams’ increase in flash rate when exposed to predators in the lab and the field. The presence of photosensitive pigments (rhodopsin, tubulin and retinochrome) was suggested from immunohistochemistry results in the ~40 eyes of C. ales in collaboration with A. Nahm-Kingston (University of Maryland Baltimore County). Transmission electron microscopy done in collaboration with R. Dubielzig, L. Teixeira, and C. Schobert (University of Iowa Veterinary School) confirmed that the morphology of the eye was inconsistent with image formation or the ability to resolve flashing in conspecifics. Therefore, the visual capability of C. ales is most likely used for predator detection. The clams’ distribution, depth, main habitats, projected sex ratios, movement based on size (sex) and sphere properties with depth were identified through SCUBA research at four field sites. The clams are found throughout the Indo-Pacific, from depths 3m to ≥50m. Their movement doesn’t vary with sex, and they exhibit a clumped distribution seemingly skewed towards males, which compounds their vulnerability in aquaria collections and highlights the need to determine their conservation status.

▼ The density, distribution and dynamics of benthic bivalve populations are believed to be largely determined by the planktonic larval phase of the life history. As the hard parts of larvae, such as the prodissoconch (larval shell), develop and grow, ambient environmental conditions are recorded as chemical signatures (elemental fingerprints). If the chemical signals of reference sites are known, the larval signatures can be matched to reference sites, hereby reconstructing the origin of the larvae. The collection and identification of larval bivalves is extremely difficult, however, previous studies have shown that the prodissoconch is retained into the juvenile phase, thus enabling juveniles to maintain a record of the larval movement. Before elemental fingerprinting can be used as a larval tracking tool, site specific signatures must be evident in the shells. As a precursor study to test the application of elemental fingerprinting to track bivalve larvae, the presence of spatial variability in shell signatures as well as the scale at which these variations occurred, were established for New Zealand conditions. Furthermore, temporal stability of the shell signatures was explored, as temporal stability is crucial if the signals of shells collected at one time are to be used as predictors of unknown samples collected at a different time. The venerid bivalve Austrovenus stutchburyi is a common and widespread constituent of New Zealand estuarine communities and were therefore selected as the study species. The chemical signatures of entire Austrovenus stutchburyi shells were examined to determine the inter-site spatial differences in elemental fingerprints of shells and also to characterise the temporal stability of the signatures. Furthermore, shells were ablated at two reference points (the prodissoconch and most recently formed shell material) to determine the intra-shell variation in the chemical signatures. Juvenile individuals were collected from 19 sites in the North Island of New Zealand as part of the whole shell spatial study. One site (in Tauranga Harbour) was examined for the temporal study, whilst four sites were used to compare intra-shell chemical variation. Whole shells were digested and analysed as solution based samples using inductively coupled ii ABSTRACT iii plasma-mass spectrometry (ICP-MS) for the spatial and temporal studies, and by laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) for the point ablation intra-shell variation study. Results showed that shell concentrations were sufficiently different to yield a classification success of 68% over 19 sites, however the classification success markedly increased as the number of sites included in the analysis decreased (e.g. 12 sites = 75%, 10 sites = 84%, 5 sites = 90%, 3 sites = 95%). Shells were successfully classified across all of the spatial scales that were tested (approximately 10 km to 1150 km). Temporal stability in chemical signatures was observed over a 44 day period. The chemical signatures were not correlated with…

▼ Resumo: Aplicações de Microscopias Eletrônicas de Transmissão (TEM) e Varredura (SEM) têm contribuído para a sistemática de moluscos bivalves e classificações de táxons mais abrangentes. Em muitos casos, os resultados dessas ferramentas metodológicas têm notavelmente complementado os estudos comparativos da anatomia interna e dos caracteres conquiliológicos, contribuindo para uma ampla compreensão das relações filogenéticas entre os representantes da classe Bivalvia. A morfologia dos espermatozóides de inúmeros táxons importantes das subclasses Pteriomorphia e Heterodonta permanece pouco ou nada estudada. A análise de espécies dessas subclasses pode corroborar estudos que abordam taxonomia e filogenia. No presente trabalho, foi realizado o estudo da ultraestrutura dos espermatozóides de espécies de bivalves das famílias Veneridae, Donacidae, Tellinidae (Ordem Veneroida, Subclasse Heterodonta,), Mytilidae (Mytiloida), Isognomonidae (Pterioida) e Ostreidae (Ostreoida) (pertencentes à Subclasse Pteriomorphia). Os espermatozóides de todas as espécies de bivalves analisadas, com exceção da espécie Tellina lineata, apresentaram uma morfologia típica de animais marinhos que liberam seus gametas fertilizando seus ovos na água do mar. A microscopia eletrônica de transmissão forneceu importantes caracteres que auxiliaram na diferenciação entre os espermatozóides das espécies Isognomon bicolor e I. alatus (única coletada em território estrangeiro); Donax hanleyanus e D. gemmula; Macoma biota e M. constricta. A célula gamética masculina de Tellina lineata foi considerada modificada, portadora de acrossomo cônico e curto, núcleo longo e helicoidal, mitocôndrias alongadas que se estendiam sobre a periferia da base nuclear, estruturas longas que se dispunham ortogonalmente (mas que não apresentavam o padrão convencional dos centríolos) e um flagelo simples. Na literatura acerca dos Bivalvia, considerase a cabeça alongada mais eficiente na penetração de óvulos que possuem ampla camada gelatinosa. O espermatozóide de Tivela mactroides (em comparação com aquele produzido por Anomalocardia brasiliana) possibilitou a descrição de determinadas características que podem contribuir para vantagens adaptativas nos ambientes nos quais os bivalves ocorrem. Uma característica interessante da cabeça alongada dos espermatozóides dos membros da família Veneridae é a presença de curvatura. Populações de Mytella podem ocorrer tanto em costões rochosos quanto em bancos de sedimento areno-lamoso. Não houve diferença entre essas populações e foi sugerido que ambas se tratam de M. charruana. A presença de perforatorium no espermatozóide de Mytella charruana permite sua alocação na subfamília Mytilinae. As descrições disponíveis na literatura sobre a morfologia do gameta masculino de ostras mostram uma significativa semelhança entre as espécies investigadas, corroborando o status monofilético da família Ostreidae. Segundo os resultados apresentados é possível afirmar que a espécie Crassostrea brasiliana ocorre na região de Cananéia.

Considering this context, in chapter 1, a survey of the aspects of the artisanal extraction activity for the mollusk Anomalocardia brasiliana (GMELIN, 1791) was carried out, noting the aspects relative to the socio-environmental perception of the women shellfishers associated to the colony of fishers Z-13 in the municipality of Senador Georgino Avelino/RN, Brazil. The methodology used was based on interviews using a structured questionnaire, applied to 41 women shellfishers. In the results, it became clear that the extraction activity is a source of income and the shellfish are used to compliment the family diet of this group. In Chapter 2, the reduction of A. brasiliana in natural stocks during rainy periods was investigated, as reported by the women shellfishers during the interviews, and could be related to the salinity of the water in the environment. In this context, an experiment was carried out in the laboratory, where the mollusks were subjected to the salinities: 5 ppt, 15 ppt, 25 ppt, 35 ppt, 45 ppt, 55 ppt and 65 ppt, with an experimental design consisted of 7 treatments with 7 repetitions distributed in 49 experimental units with 12 individuals in each experimental unit (RODRIGUES, 2015, adapted). The animals were fed with dehydrated microalgae (Spirulina spp). Among the results obtained, a greater survival of these animals was shown in the salinities of 25 ppt and 35 ppt, noting that the oscillation in the abundance of these animals throughout the year can be directly related to the salinity found in the environment. The present study showed the relevance of A. brasiliana extraction for the women shellfishers of the municipality and the survival of this mollusk at different salinities, especially in the salinities 25 ppt and 35 ppt.

Les écosystèmes côtiers sont parmi les plus vulnérables aux changements globaux actuels, qui entraînent notamment une augmentation de la température de l'eau, ainsi que de la fréquence des épisodes hypoxiques. La coquille Saint-Jacques, Pecten maximus, est une espèce subtidale évoluant à des profondeurs de 2 à 210 m. Malgré son intérêt commercial et un intérêt écologique majeur, cette espèce n'a fait l'objet que de peu d'études au niveau moléculaire. L'objectif de cette thèse était de caractériser les mécanismes moléculaires régissant l'acclimatation de cette espèce aux contraintes thermique et hypoxique. Nous avons dans un premier temps caractérisé les modifications d'expression des gènes/protéines, par des approches transcriptomiques (RNAseq) et protéomiques (2-DE), dans un tissu, le manteau, d'animaux exposés à une contrainte thermique prolongée (56 jours). Nous avons ainsi pu identifier les voies majeures de régulation (eg., AP-1), les grandes fonctions (eg., cytosquelette) et processus (eg., apoptose) impliqués dans la réponse, mais également d'observer les grandes orientations du métabolisme (eg., dégradation des lipides de réserve). La réponse des organismes à l'hypoxie dépend de leur manière de gérer les faibles teneurs en oxygène. Nous avons d'abord, par une approche comparative avec une espèce intertidale, la moule (Mytilus spp.), caractérisée la réponse physiologique de la coquille Saint-Jacques à l'hypoxie. Nous avons pu ainsi déterminer ses paramètres d'oxyregulation, plus particulièrement son Point critique en 02 (Pc02). Le développement d'une approche protéomique, couplant l'effet de la température et de l'hypoxie, nous a ensuite permis d'identifier plusieurs protéines (CK2, GLN, etc.) potentiellement impliquées dans la réponse au niveau moléculaire. Enfin, dans l'optique de mieux comprendre la physiologie particulière de ces mollusques dans leur environnement naturel, nous avons comparé les signatures protéomiques de deux populations de P. maximus évoluant dans des écosystèmes contrastés, i.e. en limite nord- (Norvège) et au centre- (Brest) de l'aire de répartition de l'espèce. Les résultats suggèrent des différences majeures entre les deux populations au niveau du cytosquelette. En conclusion, ce travail ouvre des perspectives nouvelles pour la compréhension des mécanismes moléculaires régissant l'adaptation des mollusques aux contraintes thermiques et hypoxiques, deux stress particulièrement importants pour les organismes marins dans le contexte du changement global.

Coasts are among the most vulnerable ecosystems to the ongoing global changes, which result in increased water temperatures and frequencies of hypoxic episodes. The great scallop, Pecten maximus, is a subtidal species living at depths of 2-210 m. In spite of its commercial and major ecological values, only few studies at the molecular level were performed on this species. This thesis aimed at characterizing the molecular mechanisms implied in acclimation of this species to thermal and hypoxia stresses. We first characterized the…

L’huître creuse Crassostrea gigas est le produit aquacole le plus commercialisé dans le monde. Cependant, en France et dans d’autres régions du monde, des mortalités estivales massives affectent de façon alarmante les populations naturelles et cultivées de cette espèce, surtout aux stades juvéniles. Ces évènements sembleraient être liés à un déséquilibre entre les acteurs de la triade hôte – agent pathogène – environnement, favorisant l’affaiblissement des mécanismes de défense de l’hôte, et par conséquent, l’apparition et/ou l’augmentation de maladies. Parmi les facteurs environnementaux pouvant contribuer à ce déséquilibre, les contaminants chimiques sont connus pour moduler les capacités de défense de divers organismes aquatiques. Les phénoloxydases (PO) sont les enzymes-clés d’une cascade biochimique responsable de la production de mélanine et sont impliquées dans les défenses immunitaires et dans la reconnaissance du non-soi chez les invertébrés. Récemment, une activité de type PO a été détectée chez C. gigas, et a été proposée comme biomarqueur potentiel de la contamination chimique. Cependant, de nombreuses inconnues existent quant aux différents types d’activité PO présents chez C. gigas, et à leur implication dans les mécanismes de défense chez cette espèce. Dans ce contexte général,les objectifs de cette thèse ont été d’ 1) identifier les différents types de PO présents dans différents tissus de l’huître 2)évaluer le potentiel des PO en tant que biomarqueurs dans des expériences d’exposition in vivo à des contaminants organiques, 3) évaluer le potentiel des PO en tant que biomarqueurs dans des études de biosurveillance in situ. Nous avons pu montrer, pour la première fois chez cette espèce, l’existence de deux types d’activité PO : une activité catécholase et une activité laccase. De plus, nous avons pu mettre en évidence in vitro un effet bactéricide lié à l’activité des PO contre deux souches pathogènes de l’huître, Vibrio splendidus et V. aesturianus, dont leur présence a été fréquemment associée aux phénomènes de mortalités estivales. Enfin, grâce à une analyse multi-biomarqueurs sur différents tissus de C. gigas,l’ensemble des résultats ont permis de proposer que les PO pourraient être utilisées comme biomarqueurs de stress environnemental, plutôt que de contamination, dans la surveillance de la qualité des eaux côtières et estuariennes.

The Pacific oyster Crassostrea gigas is the leading aquaculture product at the worldwide level. However, massive summer mortalities affect dramatically cultivated and natural oyster populations, especially at young life stages. These events could be linked to an unbalance between the different actors of the triad host – pathogen agent – environment, which could favour a weakening of defence mechanisms in the host, and consequently, the emergence and/or increase of diseases. Among environmental factors that could contribute to this unbalance, chemical contaminants are known to modulate defence capacities in different aquatic organisms. Phenoloxidases (POs) are the…

O alto da Bacia Hidrográfica do Rio Ribeira de Iguape foi submetido a intensa atividade mineira, cujo objeto mineral principal era a obtenção de chumbo (Pb). Durante longo período as condições de explotação foram rudimentares, não havendo controle sobre o impacto ambiental gerado durante as fases de extração e beneficiamento do minério, cujos rejeitos (escória e concentrado) foram lançados por anos diretamente no rio Ribeira de Iguape. Com o propósito de se criar uma indicação clara do comprometimento ambiental ou não da bacia hidrográfica do rio Ribeira de Iguape quanto ao teor dos metais Cd, Pb, Cr, Zn e Cu, este trabalho exibe resultados de valores que podem servir de referência em teor para estes metais. Para tanto, foram coletadas amostras de duas espécies de moluscos bivalves, Anodontites tenebricosus e Corbicula fluminea e de sedimento aluvionar, em uma porção localizada a montante das fontes de contaminação pelas atividades de mineração e fundição. Os moluscos foram coletados por exame tátil do substrato, seus tecidos foram separados das conchas, liofilizados e analisados em espectrômetro de massa (ICP/MS) e em espectrômetro de absorção atômica (AES). Os valores médios foram em sua maioria inferiores aos valores obtidos por outros autores em pontos localizados ao longo do rio Ribeira de Iguape sob a influência das atividades de mineração e fundição. Em relação às amostras de sedimento aluvionar estas foram separadas em duas porções, uma contendo sedimentos com minerais não magnéticos e a outra sedimentos com minerais magnéticos. Estas amostras foram tratadas granulometricamente e analisadas por fluorescência de raio X (FRX), a fim de se obter a concentração dos metais contidos em cada fração granulométrica. Nas amostras de sedimento não magnético, o composto químico em maior concentração foi SiO2. Quanto aos metais potencialmente tóxicos aqui investigados, todos foram encontrados nestas amostras. Já em relação ao sedimento magnético, as amostras exibiram constituição química composta principalmente por Fe2O3. Os metais Pb, Cr, Zn e Cu, foram encontrados em maior concentração nas amostras referentes as frações granulométricas mais finas, sendo a concentração do Cr nitidamente mais elevada. A elevada concentração deste metal nas amostras de sedimento magnético, quando comparada com as obtidas nas amostras não magnéticas, pode indicar uma provável origem do Cr a partir do mineral cromita (FeCr2O4). Estes dados juntamente com informações contida na literatura específica, indicam que provavelmente a origem do Cr, Pb, Zn e Cu na bacia do rio Ribeira de Iguape possui origem geogênica. De maneira geral, as concentrações dos metais potencialmente tóxicos aqui verificadas, tanto nas amostras referentes às duas espécies de moluscos quanto nas amostras de sedimentos, são inferiores, em sua maioria, às obtidas em pontos ao longo do rio Ribeira de Iguape estudados por outros autores onde há influência das atividades de mineração, o que permite considerar esses dados como referência.

Os moluscos bivalves sÃo alimentos de grande importÃncia nutricional sendo ususalmente consumidos nas regiÃes costeiras. Quando ingeridos in natura (crus) ou levemente cozidos, podem oferecer risco Ã saÃde pÃblica por serem filtradores e acumuladores de resÃduos quÃmicos e biolÃgicos, principalmente se a qualidade sanitÃria da Ãgua onde forem capturados estiverem comprometidas. A presente pesquisa tem como objetivo estudar a espÃcie Tagellus plebeius ("unha de velho") no estuÃrio do rio cearÃ em Fortaleza - Ce, considerando aspectos de seu ciclo reprodutivo, da sua biologia populacional e de suas condiÃÃes microbiolÃgicas. Para a anÃlise do ciclo reprodutivo os exemplares de T. plebeius foram coletados mensalmente no estuÃrio do rio cearÃ em Fortaleza - Ce (03, 42, 09.8 S; 35, 35, 49.0 W) no perÃodo de abril de 2006 a junho de 2007 em marÃs diurnas de sizÃgia. A cada mÃs as gÃnadas de 30 indivÃduos fram submetidas a exame histolÃgico. Para as amostragens microbiolÃgicas, as anÃlises foram feitas em dois meses da estaÃÃo seca )novembro e dezembro de 2006) e em dois meses da estaÃÃo chuvosa (marÃo e abril de 2007). Foram isoladas 22 cepas suspeitas de Salmonella spp., das quais 11 cepas foram confirmadas atravÃs do teste de sorologia com o antisoro polivalente O:H, sendo identificados 3 sorovares (S. Bredeney, S. London e S. Muenchen) e 1 (uma) cepa foi classificada atÃ subespÃcie: S. enterica subesp. enterica. Dentre os fatores ambientais observados neste estudo, a precipitaÃÃo pluviomÃtrica e a salinidade foram os que apresentaram as maiores amplitutes de variaÃÃo. O aumento da contaminaÃÃo por coliformes termotelorantes (45ÂC) na estaÃÃo chuvosa pode estar relacionado ao aporte de Ãgua doce no rio, como uma consequente diminuiÃÃo da salinidade associada a uma maior contaminaÃÃo bacteriologica. A correlaÃÃo significativa observada entre a salinidade e as fases "MaturaÃÃo/EliminaÃÃo Inicial" (M/E) e "Atresia Acular" (AC) mostra tambÃm a influÃncia desta variÃvel ambiental no desenvolvimento gonadal da espÃcie, prolongando ou reduzindo as fases do seu ciclo reprodutivo.

La palourde grise européenne, Ruditapes decussatus est un coquillage d’importance socio-économique en Europe du Sud. Sa production est basée sur le recrutement naturel, qui est sujet à de fortes fluctuations annuelles. Au Portugal, les principales zones de production de cette espèce sont les lagunes de Ria de Aveiro et Ria Formosa. Ces populations présentent des réponses différentes à l'induction de la ponte, résultat d’intérêt dans un contexte d'amélioration de la production aquacole. L'objectif de cette thèse était d'améliorer les connaissances sur la reproduction de R. decussatus en utilisant des approches génomiques et cellulaires avec pour principales applications : le conditionnement de géniteurs et la qualité des gamètes.Le cycle de reproduction de ces populations a été caractérisé par histologie pour le développement gonadique, l’aire gonadique et le diamètre de l’ovocyte. À l'exception de la dynamique de la gamétogénèse, aucune différence significative n’a été identifiée entre populations. Grâce à un effort de séquençage (Illumina) de banque d’ADNc de différents tissus/stades pour enrichir en transcrits liés à la reproduction, une puce à ADN (oligoarray) représentant 51 678 contigs a été produite et utilisée afin de caractériser les bases transcriptomiques de la reproduction de R. decussatus. Des gènes différentiellement exprimés et la voie “N-Glycan biosynthesis”, impliquées dans l'interaction spermatozoïde – ovocyte, ont été soulignés, ce qui suggère que la reconnaissance entre gamètes puisse expliquer en partie les différences de succès d'induction de ponte entre ces populations. De plus, le transcriptome d’ovocytes collectés chez 15 femelles a été analysé par puce à ADN avec pour objectif d'identifier des potentiels marqueurs de la qualité des ovocytes. Des gènes codant pour des protéines chaperonnes, dont certains caractérisés comme des ARNm maternels essentiels pour le développement précoce, sont apparus différentiellement exprimés entre ovocytes de bonne et mauvaise qualité établie sur le taux de larves D obtenu. La présente étude fournit de nouvelles informations génomiques précieuses pour la compréhension de la reproduction de cette espèce et liste des gènes candidats codant la protéine disulforide isomerase (PDI), des calmodulines et la caspase 8 comme points de départ possibles pour des études fonctionnelles. Leur implication dans les phases importantes de la reproduction comme l’interaction spermatozoïde-ovocyte, la protection de l'ovocyte, la régulation du calcium et l'apoptose ont font des marqueurs potentiels de la qualité ovocytaire de cette espèce.

The European clam, Ruditapes decussatus is considered a high value seafood product in Southern Europe. Its production is almost based on natural recruitment, which is subject to annual fluctuations. In Portugal, two of the main production areas of this species are Ria de Aveiro and Ria Formosa Lagoons. These populations were characterized by different responses to spawning induction, which is of great interest in a context of improvement of…

A Anomalocardia brasiliana está entre os moluscos bivalves marinhos mais coletados em Pernambuco, região nordeste do Brasil, esse marisco é naturalmente encontrado principalmente no litoral norte, onde a pesca artesanal sempre foi uma atividade tradicional. O presente estudo teve como objetivo avaliar as relações alométricas no crescimento e peso do marisco A. brasiliana, na praia de Mangue Seco, litoral norte de Pernambuco. Para verificar se o marisco apresentou alometria positiva, negativa ou isometria, foram realizadas regressões não lineares (metodologia Gauss Newton) entre as medidas comprimento/largura, comprimento/altura, largura/altura, peso da concha/peso partes moles e comprimento/peso (total, concha e parte mole). Ao realizar as análises da A. brasiliana verificou-se que a relação comprimento/largura foi alométrico positivo e as demais relações foram negativas. Os resultados desse estudo podem ser utilizados na elaboração de planos de manejo para o desenvolvimento da pesca e maricultura e servir como base para diagnosticar efeitos ocasionados por possíveis alterações ambientais.

Anomalocardia brasiliana is one of the most common bivalve marine mollusks found in Pernambuco, in the Northeast of Brazil. This shellfish is mainly found on the northern coast of the region, where hand fishing has always been a traditional activity. The aim of the present study was to assess the allometric ratios of growth and weight of the shellfish A. brasiliana, on Mangue Seco beach, in northern Pernambuco. Non-linear regression was performed (Gauss Newton methodology) to investigate if the shellfish exhibited positive, negative or isometric allometry using the following measurements: length/width; length/height; width/height; weight of the shell/soft tissue weight and length/weight (total, shell and soft tissue). Analysis of A. brasiliana confirmed that the length/width ratio was positively allometric whereas all other ratios were negative. The results of the present study may be used in the preparation of management plans for fishing and mariculture development and as a basis to diagnose possible effects caused by environmental changes.

▼ This study is divided into four sections beginning with a consideration of the effects of an hitherto undescribed coccidian parasite of the ovary of this bivalve on the dynamics of a particular population from Kames Bay, Millport, Isle of Cumbrae, Scotland. The parasite was found to bring about complete or partial castration of female Tellina tenuis but had no effect on males. The general biology of Tellina-tenuis is reviewed and discussed in relation to observations that were carried out over one year on the age structure, growth, density, reproduction and degree of parasitization of this bivalve. The population parameters were found to have changed little over the last fifty years. There was not found to be any significant change in the condition index that could be related to the destruction of the gonad by the parasite. This is the first description of a coccidian parasite of the ovaries of any marine mollusc. The second section describes the life cycle and developmental stages of the coccidian parasite. The parasite is believed to be monoxenous with sporogony and anisogamy orcurring in the ovary of the host. Endogenous stages were observed in the primary germ cells of the gonadal follicles. A diagnosis is presented based on the number of sprozoites per sporocyst and sporocysts per oocyst. The name Mcrocystis tellinovum (sp. nov. ) is proposed for this coccidian. The genus Merocystis belongs to the family Aggregatidae within the sub-order Eimeriorina of the order Eucoccidiorida. An ultrastructural study of both sexual and asexual stages is presented in support of this diagnosis. The third section of this study is an investigation of the observation that a large proportion of the Tellina tenuis examined histologically contained inclusion bodies within the secretory cells of the digestive gland. These inclusions were comprised of dense masses of pleomorphic mycoplasma-like organisms. The first part of this section describes the morphology and ultrastructure of these organisms and the histopathological effects on the host digestive gland. A description of the normal digestive gland iss-given including observations of the cyclic changes in appearance that take place in response to the influence of tidal rhythms. This is believed to be the first description of a mycoplasma-like organism from a marine invertebrate. The fourth section is concerned with a series of experiments to determine the nature of a virus seen in association with the mycoplasma-like organism. The virus was isolated from the host cells by density gradient centrifugation and its morphology was compared with a second virus isolated by Hill (1975) through the medium of a fish cell culture. It was found that these two viruses were quite distinct from each other. Attempts were made to propagate both viruses in an established cell line from the Atlantic salmon and the results are described and discussed.

Estudos ecotoxicológicos podem ser empregados na avaliação da qualidade de ecossistemas, por meio do uso de biomarcadores, que são alterações em parâmetros em nível subindividual que indicam que um organismo foi exposto a contaminantes. Os bivalves são organismos frequentemente utilizados em estudos ecotoxicológicos e a espécie Corbicula fluminea (Corbiculidae) está entre aquelas que mais aparecem nos estudos realizados em ambientes dulcícolas. O chorume produzido em lixões e aterros de resíduos domésticos é uma mistura complexa e variável que contém diversos tipos de compostos tóxicos, tais como metais e compostos orgânicos xenobióticos, os quais podem causar alterações em biomarcadores de animais aquáticos. No presente trabalho, fez-se o uso de biomarcadores para avaliar a toxicidade do chorume em bivalves C. fluminea em dois tipos distintos de testes de toxicidade. Foram realizados testes de toxicidade in situ em três pontos (P1, P2 e Periq3) de um córrego contaminado por chorume de aterro doméstico e, também, testes de toxicidade em laboratório com diferentes diluições (10X, 18X, 32X e 50X) do chorume bruto retirado do mesmo aterro controlado. Os biomarcadores avaliados foram de biotransformação de xenobióticos (EROD: 7-etoxiresorufina-O-deetilase; GST: glutationa S transferase; MXR: mecanismo de resistência a multixenobióticos), estresse oxidativo (ERO: geração de espécies reativas de oxigênio; CAO: capacidade antioxidante total; LPO: lipoperoxidação), danos no DNA (ensaio do cometa), conteúdo de metalotioneínas (MT) e expressão relativa dos genes piGST e MT. Além disso, nos testes de toxicidade in situ foi avaliado o acúmulo dos metais Al, Cd, Cr, Cu, Mn, Ni e Pb nas brânquias e glândulas digestivas dos bivalves. Nos testes realizados em laboratório também foram analisadas a expressão gênica dos genes da GST e MT, nos bivalves expostos por 5 dias a diluição de 50X. Os resultados mais relevantes mostram que o chorume, independente do tipo de teste de toxicidade empregado, provoca a redução da atividade da EROD em brânquias e indução na glândula digestiva, o aumento da atividade da GST, a redução do MXR, ocorrência de LPO e aumento do conteúdo de MT. O ensaio do cometa realizado mostrou que danos no DNA de hemócitos de bivalves C. fluminea ocorrem a partir de 15 dias de exposição ao chorume. O metal Cr teve maior acúmulo nos tecidos dos bivalves confinados nos três pontos do córrego contaminado por chorume, podendo este ser um potencial contaminante do chorume com ação tóxica sobre os bivalves. Conclui-se que mesmo nos experimentos em campo ou em laboratório o chorume foi tóxico para os bivalves, que apresentaram alterações mesmo no ponto mais distante da fonte de chorume e na maior diluição testada. Isto mostra que o tratamento ou diluições do chorume precisam ser maiores ou mais eficientes para evitar danos mais severos e permanentes a biota aquática.

▼ Exposed sand beaches are increasingly under pressure from human population growth and recreation. Activities, such as vehicle driving and horse riding, can pose a significant threat to specialist fauna living in the sediment. Few studies have evaluated how vehicles affect sand beach fauna and none have examined the impacts of horse users on burrowing bivalves. The research questions addressed were: do vehicles and/or horses on sand beaches impact on intertidal shellfish populations? Following on from this, can management policies mitigate any negative impacts from such activities on sand beaches? This research required an interdisciplinary approach utilising methodologies from coastal geomorphology, biological science and management. The intertidal distribution of the New Zealand surfclam Paphies donacina (southern tuatua) determined seasonally on six exposed surf beaches along Pegasus Bay. The impacts of vehicle and horse users on shellfish survival were experimentally investigated, and novel in situ methods were developed to examine the effects of horses on bivalve survival. Intertidal tuatua were small (< 30 mm) and shallowly buried. Found approximately 30 m below the last high tide line, they may be exposed to vehicle and horse users. There was a positive linear relationship between the number of vehicle passes and tuatua mortality (% tuatua mortality = 4.8 + 0.23 x number of vehicle passes). On average, horse riding resulted in 36.9% tuatua mortality within a single hoof print, but walking resulted in lower mortality than trotting or galloping. Extrapolative modelling predicted that the long-term presence of these users would be highly detrimental to shellfish. Reducing the temporal frequency and spatial extent of vehicle and horse users on sand beaches could decrease shellfish mortality. The thesis results were used to evaluate current management techniques and provide management options to minimise the potential impacts of beach users on shellfish resources.

▼ This thesis investigates the reason(s) for an anomalous distribution of mussels on Wellington’s South Coast. Wellington Harbour supports large populations the mussels (Perna canaliculus, Aulacomya maoriana and Mytilus galloprovincialis) however; all these species are absent from the nearby South Coast. The physical difference between Harbour and Coastal sites was confirmed from water samples taken at eight sites inside and outside Wellington Harbour between September 1998 and February 2000. These data showed significant differences between Harbour and Coastal sites in seven of eleven parameters tested. Larval densities were investigated at Harbour and Coastal sites; data showed larval density to be approximately an order of magnitude greater in Harbour waters compared to the Coast. Larval density in Coastal waters reached a maximum of 380 mˉ³ and is therefore not expected to be a major limiting factor. Similar results were found for studies of settlement density on artificial substrates. Settlement at Harbour sites was approximately 10 times that at Coastal sites, however, mussel densities of up to ≈3700 mˉ² at Coastal sites indicate that settlement is also unlikely to be a factor contributing to mussel absence. Comparisons were made of body condition index between Harbour mussels and those from the Harbour relocated to the Island Bay Marine Laboratory (IBML) on Wellington’s South Coast. All mussel species experienced a significant decrease in condition at IBML when compared with those from the parent population in Wellington Harbour. Levels of mortality were high in P. canaliculus (60%) and M. galloprovincialis (70%) and moderate in A. maoriana (30%). This indicated the possibility of nutrient limitation as a cause of mussel absence. This was corroborated by a similar study using RNA:DNA ratio as a biochemical index of condition. Mussels held at IBML experienced a significant decrease in RNA:DNA compared to those from the parent population within the Harbour. Further investigation of nutrient limitation was conducted by way of feeding experiments to estimate the scope for growth (SFG) of each mussel species. In P. canaliculus, SFG had a mean (±SD) of 45.6 J gˉ¹ hˉ¹ (±78.9) and only 27% of observations were negative. A. maoriana had lower SFG estimates, mean SFG was 19.1 J gˉ¹ hˉ¹ (±66.7) and negative SFG was recorded 43% of the time. M.galloprovincialis had mean SFG of 1.26 J gˉ¹ hˉ¹ (±39.1), 52% of SFG estimates were negative. While these data do not overwhelming support the hypothesis of nutrient limitation, they do go some way toward corroborating the findings of the condition index experiments. Models to predict SFG were derived from data in the feeding experiments, these models were derived from a small range of low seston concentrations. A second group of models was derived from studies conducted by Gardner (2001) to give a broader range of seston concentrations. Seston data from the water sampling described above were used to estimate SFG at eight sites inside and outside the Harbour over the period from… Advisors/Committee Members: Gardner, Jonathan.

▼ Spencer Gulf is a large, shallow, metahaline embayment along the southern Australian continental margin (~22,000 km2, > 60 m water depth). The gulf experiences inverse estuarine circulation and seasonally fluctuating water temperatures, salinities, and nutrient levels. The gulf floor is covered with temperate carbonate sediments (sands, gravels, and muds) that are skeletal remains of heterozoans; bivalves, coralline algae (rhodoliths), bryozoans, benthic foraminifera, and echinoids are common constituents throughout. These carbonates are interpreted to be accumulating in five depositional environments: dense seagrass meadows, sand flats with sparse seagrass growth, rhodolith pavements, open gravel/sand barrens, and muddy seafloors. Detailed seasonal oceanographic data and hydrodynamic model outputs were used to delimit oceanographic influences on sedimentation patterns. The depth of the euphotic zone is interpreted as the most important control on benthic environment distributions within the gulf. Salinities, hydrodynamics, and nutrient concentrations also affect biological assemblages and facies patterns. Seagrasses and rhodoliths require sufficient light for growth and, thus, compete for space on euphotic seafloors. Seagrasses colonize the shallowest, best-illuminated areas. Rhodolith pavements occur in regions of the gulf where seagrasses are excluded: seafloors where surface-water nutrients promote growth of phytoplankton that decrease light penetration, and energetic channels with high bottom-water currents. Calm, subphotic seafloors are characterized by soft sediment environments (open gravels, sands, and muds). Benthic calcareous organisms are surprisingly diverse throughout the gulf, despite elevated seawater salinities (up to 47‰). Abundant carbonate muds set Spencer Gulf apart from other shallow temperate provinces. The origin of this mud is primarily from the breakdown of skeletal particles via maceration. Mineralogical composition is, therefore, a mixture of aragonite, intermediate-Mg calcite, and low-Mg calcite. Rhodolith pavement deposits were investigated in detail to determine how oceanographic conditions influence sedimentation in these environments. Rhodolith pavements provide habitats for diverse calcareous invertebrates, which can be used as environmental indicators. The rhodoliths themselves within Spencer Gulf, however, do not show morphological differences that can be used as indicators of water energy levels, as some authors have suggested. This study demonstrates that integration of detailed oceanographic data and facies analysis aids interpretations of benthic environments and sediment distribution patterns.
