Hemócitos de Bradybaena similaris e Megalobulimus abbreviatus (Gastropoda, Stylommatophora)
Provedor de dados: 76
Autores: Rohr,Roberta A.; Amato,Suzana B.
Os hemócitos atuam no sistema de defesa contra organismos invasores e partículas estranhas, auxiliando o reconhecimento do que é próprio do corpo dos grastrópodes e o que não é. São escassas as informações e estudos sobre os hemócitos em espécies de moluscos saudáveis (sem infecções), principalmente em Bradybaena similaris (Fèrussac, 1821) and Megalobulimus abbreviatus (Bequaert, 1948). Portanto, este trabalho tem como objetivos a caracterização e quantificação dos hemócitos presentes na hemolinfa destas duas espécies. Neste trabalho, foram identificados três tipos celulares na hemolinfa de ambas espécies: as células redondas, hialinócitos e granulócitos. Os três tipos de hemócitos foram medidos e foi calculada a média do diâmetro total e do núcleo para...

Divergence genetique de quelques populations naturelles de Cepaea nemoralis et Cepaea hortensis en France
Provedor de dados: 5
Autores: Guiller, A; Madec, L.
Electrophoretic analysis of eight polymorphic loci in 23 mixed or monospecific populations of Cepaea nemoralis and Cepaea hortensis indicates important genetic dissimilarities between Breton and Pyrenean areas. The concordance between groups of samples and various latitudinal or altitudinal zones suggests that the influence of climatic factors could be involved. Founder effects also seem to increase the differentiation in some populations; the lower genetic variability in three pyrenean samples probably submitted to frequent extinctions could illustrate this process. Nevertheless, divergences corresponding to plurispecific samples suppose the absence of interactions between the two species.

Development of genomic probes for detection of hepatitis A virus and enteroviruses in shellfish
Provedor de dados: 5
Autores: Apaire, M; Leguyader, F; Besse, B; Billaudel, S.
The development of molecular biology techniques has modified research procedures for certain viruses, particularly hepatitis A virus (HAV) and enteroviruses. Accordingly, we designed cDNA and RNA genomic probes to detect viruses in shellfish in the environment. Better sensitivity was noted with RNA than cDNA probes: only 17/83 shellfish samples were positive with HAV and enterovirus DNA probes, where as 42/83 were positive with HAV and enterovirus RNA probes.

Systematics and phylogeny of the caryophyllidia-bearing dorids (Mollusca, Nudibranchia), with descriptions of a new genus and four new species from Indo-Pacific deep waters
Provedor de dados: 5
Autores: Valdes, A; Gosliner, Tm.
The phylogenetic relationships of the caryophyllidia-bearing dorids are studied, based on the examination of the type species of all the genera previously described. The phylogenetic hypothesis supports that the caryophyllidia-bearing dorids area monophyletic group and the sister group of the clade formed by Asteronotus Ehrenberg, 1831 and Halgerda Bergh, 1880. Several genera previously considered as valid or regarded as uncertain are here synonymized: Peronodoris Bergh, 1904, Trippa Bergh, 1877, Phlegmodoris Bergh, 1878, Petelodoris Bergh, 1881, Kentrodoris Bergh, 1876, Audura Bergh, 1878, Centrodoris P.

Microarray-Based Identification of Gonad Transcripts Differentially Expressed Between Lines of Pacific Oyster Selected to Be Resistant or Susceptible to Summer Mortality
Provedor de dados: 5
Autores: Fleury, Elodie; Moal, Jeanne; Boulo, Viviane; Daniel, Jean-yves; Mazurais, David; Henaut, Alain; Corporeau, Charlotte; Boudry, Pierre; Favrel, Pascal; Huvet, Arnaud.
Summer mortality of the Pacific oyster Crassostrea gigas is the result of a complex interaction between oysters, their environment, and pathogens. Heredity appears to be a major factor determining the sensitivity of oysters to summer mortality, allowing resistant (R) and susceptible (S) lines to be produced. We conducted genome-wide expression profiling of R and S gonads during the 3-month period preceding a summer mortality event, using a cDNA microarray that we designed. ANOVA analysis revealed that 34 genes were differentially expressed between R and S lines on four dates preceding the mortality event. Annotation of some of these genes highlights reproduction and its allocation and antioxidant defenses as the main pathways that operate differentially...

Campagne d'évaluation du stock de palourdes du bassin d'Arcachon - Année 2006
Provedor de dados: 5
Autores: Caill-milly, Nathalie; Duclercq, Benoit; Morandeau, Gilles.
Between 1980 and 1986, some Arcachon oyster farmers took up breeding the Japanese clam on the foreshore (Robert et Deltreil, 1990). This production was short lived. The steep fall in prices due to economic competition from Spain, Portugal, Italy and Tunisia, predator action such as the trigger fish (Popovsky et al., 1999), added to the significant amount of mortality that occurred in the summer and autumn of 1992 that affected two-thirds of the total stock, led to clam farming being abandoned at the end of the 1980s.  In the Arcachon basin, the Japanese clam (Ruditapes philippinarum) population, now natural to the area, has found favourable conditions for development and is expanding rapidly there. This species has been supplanting the local species...

The population of Pinctada margaritifera and Pinctada maculata lay eggs throughout the year. Temperature variations induce huge but asynchronous laying. Preferential periods of gonad maturity correspond to the season changings in both species. However. some differences between the two specics are noticed. Both species are protandric hermaphrodites. Female condition is unstable: a reversion to the male condition may be observed and is probably linked with stress. The average size for the first sexual maturation as weil as for sexual conversion are specified in P. margaritifera. The breeding conditions induce modifications in some reproductive cycle processes (maturation, sex-ratio). Some conditions suitable for reproduction may become unfavorable to...

Introduction: During each summer season, the IFREMER laboratory of Arcachon monitors, within the framework of the agreement with the Arcachon- Aquitaine Shellfish Farming Regional Section (SRC), the reproduction of cup oysters in the Arcachon basin.  This monitoring has as its goal to furnish oyster farmers with the information needed to implement spat catches: - dates and size of egg clutches, - larvae development rate, - presence in the environment of more evolved stages (close to fixation).  Reproduction was monitored between mid-June and mid-September, plankton was fished four times per week at the various sites representative of the basin. Oyster larvae at various stages are enumerated there.  At the end of the reproductive season (September to...

Diseases in mollusc hatcheries and their paraedox in health management
Provedor de dados: 5
Autores: Berthe, Franck.
Global molluscan aquaculture production is continuously increasing, dominated by five species, among which the Pacific cupped oyster, Crassostrea gigas, predominates. Hatchery production is accompanying this increase to assist consistent availability of juveniles for restocking, fishery enhancement, genetic improvements as well as for species diversification. Hatchery development contributes significantly to the demand for international transfers of live molluscs; a consequence of which pathogen transfer via transfer of live molluscs is currently recognised as a major cause of epizootic disease outbreaks. Diseases are a primary constraint to mollusc aquaculture growth and sustainability, severely impacting socioeconomic development in many countries....

Problèmes de santé publique liés à la consommation de fruits de mer
Provedor de dados: 5
Autores: Lupo, Coralie; Angot, J.-l.
Seafood could be a solution to meet global food demand that will double by 2050. Seafood includes a wide variety of edible marine organisms, except fish and mammals. These are molluscs, crustaceans, echinoderms and algae. Like any food, seafood can involve hazards transmitted to humans through food, which affect the health of the consumer. These hazards are both biological (viruses, bacteria, parasites) and chemical (toxins, allergens, chemicals, microplastics). The exposure of populations to these hazards through seafood consumption can be notably explained by their mode of production and the dietary habits. Firstly, the sanitary quality of products reflects the quality of the aquatic environment from which they are taken, which can be contaminated by...

Hemic proliferative disease in the bay mussel, Mytilus edulis, has been studied following mortalities in Washington State (USA). The disease has been reproduced in the labortory. The establishment of this experimental model led to study tumoral characteristics of the atypic hemocytes : ultrastrure, in vitro cultivation, transplantation. The infectious etiology of this tumor has been verified. It has been hypothesized to result from a viral infection since retrovirus-like particules have been observed following induction by bromodeoxyuridine.

Inadequacy of bacterial indicators for assessing elimination rates of viruses from molluscan shellfish
Provedor de dados: 5
Autores: Burkhardt, W; Watkins, W; Rippey, S.
The reported incidence of shellfish-borne illness in the United States increased dramatically during the last decade. Most of the outbreaks are attributed to diseases of viral aetiology. These human health problems result primarily from the ingestion of raw shellfish which have accumulated enteric pathogens from environmental waters or from wet storage facilities. Our studies have demonstrated that hard-shelled clams concentrate different indicator micro-organisms at variable and unpredictable rates during the year. In temperate waters, this has been observed at two abbreviated periods in mid-spring and again in late fall when accumulation rates increased dramatically. Moreover, these rates were not generally coincident for viruses and bacteria. In...

Uncovering the shell game with barcodes: diversity of meiofaunal Caecidae snails (Truncatelloidea, Caenogastropoda) from Central America
Provedor de dados: 5
Autores: Egger, Christina; Neusser, Timea P.; Norenburg, Jon; Leasi, Francesca; Buge, Barbara; Vannozzi, Angelo; Cunha, Regina L.; Cox, Cymon J.; Jörger, Katharina M.
Caecidae is a species-rich family of microsnails with a worldwide distribution. Typical for many groups of gastropods, caecid taxonomy is largely based on overt shell characters. However, identification of species using shell characteristics is problematic due to their rather uniform, tubular shells, the presence of different growth stages, and a high degree of intraspecific variability. In the present study, a first integrative approach to caecid taxonomy is provided using light-microscopic investigation with microsculptural analyses and multi-marker barcoding, in conjunction with molecular species delineation analyses (ABGD, haplotype networks, GMYC, and bPTP). In total 132 specimens of Caecum and Meioceras collected during several sampling trips to...

Microarray analysis highlights immune response of Pacific oysters as a determinant of resistance to summer mortality
Provedor de dados: 5
Autores: Fleury, Elodie; Huvet, Arnaud.
Summer mortality of Crassostrea gigas is the result of a complex interaction between oysters, their environment, and pathogens. A high heritability was estimated for resistance to summer mortality, which provided an opportunity to develop lines of oysters that were resistant (R) or susceptible (S) to summer mortality. Previous genome-wide expression profiling study of R and S oyster gonads highlighted reproduction and antioxidant defense as constitutive pathways that operate differentially between these two lines. Here, we show that signaling in innate immunity also operates differentially between these lines, and we hypothesize that this is at the main determinant of their difference in survival in the field. A reanalysis of our published microarray data...

Autores: Harney, Ewan; Dubief, Bruno; Boudry, Pierre; Basuyaux, Olivier; Schilhabel, Markus B.; Huchette, Sylvain; Paillard, Christine; Nunes, Flavia.
The European abalone Haliotis tuberculata is a delicacy and consequently a commercially valuable gastropod species. Aquaculture production and wild populations are subjected to multiple climate-associated stressors and anthropogenic pressures, including rising sea-surface temperatures, ocean acidification and an emerging pathogenic Vibrio infection. Transcript expression data provides a valuable resource for understanding abalone responses to variation in the biotic and abiotic environment. To generate an extensive transcriptome, we performed next-generation sequencing of RNA on larvae exposed to temperature and pH variation and on haemolymph of adults from two wild populations after experimental infection with Vibrio harveyi. We obtained more than 1.5...

Transcriptomic response of the Pacific oyster Crassostrea gigas to hypoxia
Provedor de dados: 5
Autores: Sussarellu, Rossana; Fabioux, Caroline; Le Moullac, Gilles; Fleury, Elodie; Moraga, Dario.
Marine intertidal organisms commonly face hypoxic stress during low tide emersion; moreover, eutrophic conditions and sediment nearness could lead to hypoxic phenomena; it is indeed important to understand the molecular processes involved in the response to hypoxia. In this study the molecular response of the Pacific oyster Crassostrea gigas to prolonged hypoxia (2 mg O-2 L-1 for 20 d) was investigated under experimental conditions. A transcriptomic approach was employed using a cDNA microarray of 9058 C. gigas clones to highlight the genetic expression patterns of the Pacific oyster under hypoxic conditions. Lines of oysters resistant (R) and susceptible (S) to summer mortality were used in this study. ANOVA analysis was used to identify the genes...

Le controle chimique et biologique de Lymnaea truncatula Mueller. Etude des effets a long terme
Provedor de dados: 5
Autores: Rondelaud, D.
The treated habitats have not been recolonized by Lymnaea truncatula . Four aquatic snail species showed an increase in their numbers: L. glabra in the stations of Haute-Vienne, L. glabra, Physa acuta, P. hypnorum and Planorbis rotundatus in the habitats of Indre. The numbers of L. glabra and P. acuta reached their maximum on the third year and decreased thereafter; those of P. hypnorum and P. rotundatus slightly increased from the fourth or the fifth years treatment. The colonization of L. truncatula habitats was incomplete and did not reach over 50% of the surface for L. glabra and P. acuta , 20% for P. hypnorum and P. rotundatus . The bivalve Pisidium casertanum did not recolonize treated habitats. There were no modifications in the numbers of...

Hermafroditismo Funcional de la Gónada de Fissurella crassa (Mollusca: Fissurellidae)
Provedor de dados: 77
Autores: Olivares Paz,Alberto; Jofré Madariaga,David; Alvarez Mazú,Carlos; Bustos-Obregón,Eduardo.
La costa del Pacífico sudoriental es el hábitat de las 13 especies de lapas descritas del subgénero Fissurella Brugière. En estas especies no existe dimorfismo sexual, los animales son dioicos, el sexo se reconoce explorando directa o indirectamente las gónadas y no tienen procesos de reversión sexual. La presencia de un organismo de Fissurella crassa con gónada formada por porciones de ovario y otras de testículo con capacidad para generar óvulos y espermatozoides, evidencia la potencialidad que los organismos de Fissurella poseen para desarrollar el hermafroditismo funcional. Sin embargo, el presente hallazgo no permite inferir si el agente desencadenante del desarrollo sincrónico funcional de la gónada hermafrodita es un factor endógeno y/o asociado a...

Microscopic Anatomy of the Male Reproductive System in Echinolittorina peruviana (Mollusca: Caenogastropoda)
Provedor de dados: 77
Autores: Castillo,Viviana M; Brown,Donald I.
Echinolittorina peruviana (Lamarck, 1822), a gonochoric representative of the Littorinidae on the SE Pacific coast, has a male reproductive system adapted for internal fertilization. We describe this system at both macro- and microscopic levéis, particularly the compartmentalized organization of the gonad, and the morphology of the penis. The male reproductive system has a variegated conical gonad-digestive gland complex. The gonad presents three compartments, 1) gametogenic acinar among the glandular acini, 2) periacinar with a layer of fusiform somatic cells and, 3) interacinar with glycogen storage cells shared with glandular acini. Spermatogenesis occurs within the acinar gametogenic compartment, with the germinal line organized in centripetal form...

The stratigraphy and regional structure of Miocene deposits in western Amazonia (Peru, Colombia and Brazil), with implications for late Neogene landscape evolution
Provedor de dados: 16
Autores: Wesselingh, F.P.; Hoorn, M.C.; Guerrero, J.; Räsänen, M.E.; Romero Pittmann, L.; Salo, J.A.
A biozonation based on molluscs is proposed for Miocene deposits of western Amazonia (Peru, Colombia and Brazil), commonly referred to as the Pebas Formation. The new zonation refines existing pollen zonations and provides a key for the quick assessment of the stratigraphic position of Neogene deposits in the field. The regional distribution of twelve mollusc zones reveals a structuring of geological units around the broad Iquitos-Araracuara anteclise. The structure of the subsurface appears to have been a major factor in the determination of present-day second and lower order river courses in the study area. Based on this work a biostratigraphic framework for Miocene deposits of western Amazonia, including fossiliferous deposits from adjacent basins...

A Miocene perspective on the evolution of the Amazonian biota
Provedor de dados: 16
Autores: Wesselingh, F.P.; Salo, J.A.
Between c. 23 and 8 Ma, western Amazonia was occupied by the vast Pebas long-lived lake/wetland system. The Pebas system had a variety of influences over the evolution of Miocene and modern Amazonian biota; it formed a barrier for the exchange of terrestrial biota, a pathway for the transition of marine biota into freshwater Amazonian environments, and formed the stage of remarkable radiations of endemic molluscs and ostracods. The lithological variation of the Pebas Formation has furthermore enhanced edaphic heterogeneity in western Amazonia, sustaining present-day high terrestrial diversity in the region.

Sexual selection on land snail shell ornamentation: a hypothesis that may explain shell diversity
Provedor de dados: 16
Autores: Schilthuizen, M.
Background: Many groups of land snails show great interspecific diversity in shell ornamentation, which may include spines on the shell and flanges on the aperture. Such structures have been explained as camouflage or defence, but the possibility that they might be under sexual selection has not previously been explored.   Presentation of the hypothesis: The hypothesis that is presented consists of two parts. First, that shell ornamentation is the result of sexual selection. Second, that such sexual selection has caused the divergence in shell shape in different species.   Testing the hypothesis: The first part of the hypothesis may be tested by searching for sexual dimorphism in shell ornamentation in gonochoristic snails, by searching for increased...

The molluscs of the brackish waters in the Netherlands (Mollusca)   The Netherlands is a river delta rich in brackish waters. The organisms in these waters need to be adapted to extreme conditions, especially large fluctuations in chlorinity. However, several species occur optimally in this habitat. In this paper a review is presented of the molluscs living in brackish waters in the Netherlands. All available data from literature, collections, literature and databanks were compiled for this cause. In The Netherlands a large variety of brackish waters can be found, like lakes, canals, old creeks, shallow pools, lagoons, estuaries and dykes. This paper focusses on the waters on the landside of the dikes. All species found in these waters are treated here....

Belemnitellid coleoids (Mollusca, Cephalopoda) from the type Maastrichtian, the Netherlands and Belgium
Provedor de dados: 16
Autores: Jagt, J.W.M.
Belemnitellid coleoids abound at some levels within the Gulpen and Maastricht formations in the study area, and ‘belemnite graveyards’ have long been known from the Bovenste Bos (Epen) and Slenaken-Beutenaken areas in southern Limburg, the Netherlands. Recent studies have demonstrated the presence of at least three species of the genus Belemnitella d’Orbigny, 1840, and five of Belemnella Nowak, 1913, and its subgenera Belemnella, Pachybelemnella Schulz, 1979, and Neobelemnella Naidin, 1975. Representatives of Belemnitella junior Nowak, 1913, and Belemnella (Neobelemnella) gr. kazimiroviensis (Skołozdrówna, 1932) are the only coleoids to reach the Cretaceous-Paleogene (K/Pg) boundary, and members of the latter group may even have persisted into the earliest...

Two new gastropods, Elysia bangtawaensis and E. siamensis from southern Thailand (Opisthobranchia, Sacoglossa, Elysiidae)
Provedor de dados: 16
Autores: Swennen, C.
Two new Elysia species were found in brackish mangrove habitats in the southern part of the Gulf of Thailand in the area around Pattani. Elysia bangtawaensis, a large species with grooved rhinophores, was discovered living on bare mud in mangrove forests. This species looks like a fallen leaf and shows sophisticated phototrophic behaviour enabling it to survive without feeding while producing many eggs over a long period. Elysia siamensis, a small species, was found on filamentous green algae in a brackish channel. The latter species has long, thin, cylindrical rhinophores, and is further characterized by a screw-like penis, and a long thin process on the tip of its metapodium.

During the NNM/Maluku Expedition 1996, in the framework of the NNM Fauna Malesiana Marine Program, a shrimp belonging to the species Periclimenes imperator Bruce, 1967, was found on a nudibranch while diving at 20 m depth in Seri Bay, on the south coast of Ambon. Periclimens imperator has been recorded throughout the tropical Indo-West Pacific, from East Africa and the Red Sea to Hawaii, from nudibranch and holothurian hosts. The nudibranch was identified as Chromodorus magnifica (Quoy &amp; Gaimard, 1832) (see Rudman, 1982: 216-219, figs. 17A, B, 18, 19).

Community ecology of tropical forest snails: 30 years after Solem
Provedor de dados: 16
Autores: Schilthuizen, M.
Since Solem’s provocative claim in the early 1980s that land snails in tropical forests are neither abundant nor diverse, at least 30 quantitative-ecological papers on tropical land snail communities have appeared. Jointly, these papers have shown that site diversity is, in fact, high in tropical forests; often more than 100 species have been recorded per site, which is somewhat more than normally found at sites in higher latitudes. At the same time, however, point diversities (which usually range between 10 and 30 species per quadrat) appear to be no different from the ones recorded for temperate localities, which suggests that the number of ways in which syntopic resource space can be subdivided among different land snail species has an upper limit that...

Comparative reproductive anatomy in the South African giant land snails (Gastropoda: Pulmonata: Achatinidae)

The history and current taxonomic status of 62 nominal taxa are revised that have been associated in the literature with the subgenus Tholachatina Bequaert, 1950, of genus Archachatina Albers, 1850, and the genus Cochlitoma Férussac, 1821, in the land snail family Achatinidae Swainson, 1840. Tangible, reliable characters have been found in the detailed features of the reproductive anatomy in this family. The results of comparative anatomical study convincingly reflect phylogeny in contrast to the comparative study of only the shell characters. This latter more strongly reflects the effects of the intrinsically variable environment over time. In the present study, both sets of characters are needed to refine identification.

Gastropod skeletal defences: land, freshwater, and sea compared
Provedor de dados: 16
Autores: Vermeij, Geerat J.
Predation is a primary agency of natural selection affecting  the evolution of skeletal form in gastropods. The nature of  antipredatory defence depends on how predators attack their  prey as well as on the types and quantities of resources that  are available to the potential victims. Here I review the five  main methods of predation on shell-bearing gastropods (swallowing  prey whole, apertural entry, drilling, shell breakage,  and partial consumption) and 31 categories of shell and opercular  defence that are effective at one or more of the three  stages of predation (detection, pursuit, and subjugation).  These categories are evaluated for marine Palaeozoic, marine  Late Mesozoic to Recent, freshwater, and terrestrial environments.  The five types of...

Two new sacoglossans (Gastropoda: Opisthobranchia) from Thailand
Provedor de dados: 16
Autores: Swennen, C.
Two new sacoglossans were found in brackish mangrove habitats near Pattani in the southern part of the Gulf of Thailand. Both are small species (&amp;lt; 10 mm) living hidden in clay with small green algae high in the intertidal zone becoming not submerged for days. They have black pigment on the dorsal side and their bodies clearly consist of two parts. One is named Gascoignella nukuli n. sp., which looks similar to G. aprica Jensen, 1985 from Hong Kong, but differs in radula, penial spine, body proportions and habitat. The other is G. jabae n. sp., which has two parallel cerata instead of a visceral sack on the posterior side of the body.

Pectinoidea (Mollusca, Bivalvia, Propeamussiidae, Entoliidae and Pectinidae) from the Austral Islands (French Polynesia)
Provedor de dados: 16
Autores: Dijkstra, H.H.; Maestrati, P.
Twenty-nine species of Pectinoidea (12 Propeamussiidae, 1 Entoliidae, 16 Pectinidae) are recorded from the Austral Islands, the southernmost archipelago of French Polynesia. One genus (Pectinidae: Lamellipecten n. gen.) and five species (Propeamussiidae: Parvamussium australanum n. sp., Cyclochlamys australensis n. sp., Cyclopecten ambiguus n. sp.; Pectinidae: Lamellipecten aduncus n. gen., n. sp., Mimachlamys erycina n. sp.) are new to science, and most others are new records for the archipelago. The near-shore fauna of Rapa has 12 species of Pectinidae, and half of these have narrow-range distributions. Such a remarkably high level of marine endemism is shared by other mollusc taxa on Rapa.

Results of the Rumphius Biohistorical Expedition to Ambon (1990). Part 13. Mollusca, Bivalvia, Cardiidae
Provedor de dados: 16
Autores: Poorten, J.J. ter.
31 Cardiidae species have been collected in Ambon, Indonesia by the Rumphius Biohistorical Expedition, comprising circa 40% of the known species of this family from the Indonesian archipelago. Seven of these could be traced to the figures given by Rumphius (1705) and an additional two, taking into account some reservations about the identity of Rumphius' depicted shells. This implies that all but one of Rumphius' species, viz. Tridacna (Tridacna) gigas (Linnaeus, 1758), have been reencountered by the present expedition. The expedition has yielded the first Indonesian published records of two species: Fulvia (Laevifulvia) lineonotata Vidal, 1994 and Acrosterigma dianthinum (Melvill &amp; Standen, 1899). For the latter this implies a considerable range...

Beiträge zur Kenntnis der Pupillacea : XI. Speleodentorcula Beroni gen. &amp; spec. nov. (Mollusca: Gastropoda: Orculidae) Aus einer Höhle in Euboea, Griechenland
Provedor de dados: 16
Autores: Gittenberger, E.
A new troglobitic genus and species, viz. Speleodentorcula beroni gen. &amp; spec. nov., is described from the island of Euboea, Greece. The species, known from a single cave only, is quite isolated systematically. According to the structure of its shell and the genitalia S. beroni should be classified with the Orculidae. Within this family Speleodentorcula is most similar to Walklea anatomically; conchologically there is some vague resemblance to Fauxulus (apertural denticles) and Odontocyclas, Walklea, Fauxulus and Afriboysidia (surface sculpture). Speleodentorcula alone is considered the sister group of the taxon encompassing these last mentioned four genera.

Miocene freshwater Mollusca from western Brazilian Amazonia
Provedor de dados: 16
Autores: Wesselingh, F.P.; Ranzi, A.; Räsänen, M.E.
Thirteen species of fossil molluscs are reported from the Solimões Formation of western Brazilian Amazonia. Based on mammalian chronology of the Solimões Formation and radiometric ages reported from coeval deposits in adjacent Peru, the age of the fauna is established as Late Miocene. The fauna includes five prosobranch gastropod species, seven pearly freshwater mussel species and one sphaeriid bivalve species. The supposed presence of Pachydon (Corbulidae: Bivalvia) in these deposits is rejected; Pachydon acreanum, whose status has long been uncertain, is transferred to the unionoid genus Callonaia. The Solimões mollusc fauna is entirely composed of obligate freshwater taxa, resembling species-poor modern Amazonian fluvial faunas. The presence of the...

An overview of the land-snail fauna of the Lesser Antillean island of Dominica is given, based on data from literature and four recent surveys. There are 42 taxa listed, of which the following species are recorded for the first time from the island: Allopeas gracile (Hutt on, 1834), A. micra (d’Orbigny, 1835), Beckianum beckianum (L. Pfeiffer, 1846), Bulimulus diaphanus fraterculus (Potiez &amp; Michaud, 1835), Deroceras laeve (Müller, 1774), Sarasinula marginata (Semper, 1885), Streptostele musaecola (Morelet, 1860) and Veronicella sloanii (Cuvier, 1817). The enigmatic Bulimulus stenogyroides Guppy, 1868 is now placed in the genus Naesiotus Albers, 1850. Helicina epistilia Guppy, 1868 is now considered a synonym of H. platychila (Megerle von Mühlfeld,...

I made use of the known dates of reclamation (and of afforestations) in the IJsselmeerpolders in The Netherlands to assess evolutionary adaptation in Cepaea nemoralis. At 12 localities (three in each polder), I sampled a total of 4390 adult individuals in paired open and shaded habitats, on average 233m apart, and scored these for genetic shell colour polymorphisms. The results show (highly) significant differentiation at most localities, although the genes involved differed per locality. Overall, though, populations in shaded habitats had evolved towards darker shells than those in adjacent open habitats, whereas a 'Cain &amp; Sheppard' diagram (proportion yellow shells plotted against ‘effectively unbanded’ shells) failed to reveal a clear pattern. This might suggest that thermal selection is more important than visual selection in generating this pattern. Trait differentiation, regardless of whether they were plotted against polder age or habitat age, showed a linear increase of differentiation with time, corresponding to a mean rate of trait evolution of 15–31 kilodarwin. In conclusion, C. nemoralis is capable of rapid and considerable evolutionary differentiation over 1–25 snail generations, though equilibrium may be reached only at longer time scales

Mytilus antiquorum J. Sowerby, 1821, is recorded from the Coralline Crag Formation of East Anglia (UK) and the Lillo Formation (Oorderen, Kruisschans and Merksem members) of the Antwerp area (Belgium). The species is diagnosed on the basis of newly collected material and differentiated from modern European mussel species. The presence of M. antiquorum in the southern North Sea Basin is restricted to the Middle (Piacenzian) and early Late Pliocene (Gelasian). A possible occurrence of the species in the latest Pliocene of northern Greenland is discussed. A second Middle- Late Pliocene North Sea Basin species, tentatively referred to as M. edulis forma giganteus Wood, 1874, is diagnosed and discussed. The systematic status of this species remains unsolved. In...

On the only Greek Sphincterochila species, two Libyan close relatives, Cerigottella subgen. nov., and an extended diagnosis of the Sphincterochilidae (Mollusca, Gastropoda Pulmonata)
Provedor de dados: 16
Autores: Gittenberger, E.
From Greece, based on conchological characters, a single, endemic Sphincterochila species has been reported about a century ago. Its occurrence is still thought to be restricted to the islet of Andikithira. The structure of the genitalia, hitherto unknown, demonstrates that it concerns a separate species indeed; its closest relatives known are two Libyan species. These three species differ from the Sphincterochila species studied so far most clearly by the stimulatory organ, inserting not on the genital atrium but far more distally on the vagina. They are classified within Cerigottella subgen. nov.

Olssoνella Scalatella (Guppy) living off northern South America (Mollusca: Neogastropoda: Cancellariidae)
Provedor de dados: 16
Autores: Verhecken, A.
Olssonella scalatella (Guppy, 1873), originally described from early Pliocene deposits in Jamaica, still occurs as a recent species off the northern coast of S. America. This opinion is based on shells collected off Surinam and French Guyana, fossil specimens from the type-locality, and data from the literature. O. smithii (Dall, 1888) is considered a closely related recent species, occurring more to the north; it differs from O. scalatella mainly in characters of the protoconch. Conchological characters of the two taxa are discussed and some general notes are given concerning the importance of protoconch characters.

The gut contents of five juvenile individuals of the loggerhead turtle Caretta caretta (L.) from waters around Madeira, Selvagem Grande (Selvagens Islands) and São Miguel (Azores) were analysed macro- and microscopically. Macroscopic investigations showed that epipelagic salps (e.g., Pyrosoma atlanticum Péron) and gastropods (e.g., Ianthina spp. and Pterotrachea spp.) constituted an important part of the food remains present in these loggerheads. To a lesser extent this also holds for organisms such as goose-barnacles (Lepas spp.). and Idotea metallica Bosc, which live on drifting materials, including algae. Microscopic examination revealed the presence in all turtles of large numbers of nematocysts, deriving mainly from Siphonophora and to a lesser extent...

The upper sample of Middle Eocene (Lutetian) age yielded just a few unidentifiable limacinids. The section between 507.5-607.0 m, of Early Eocene (Ypresian) age, yielded poorly preserved pteropods and demonstrated that the complete interval belongs to pteropod zone 9. Apart from the most abundant species, Camptoceratops priscus, which is the index taxon of pteropod zone 9, the section yielded Heliconoides mercinensis and Limacina taylori, which are known to accompany the index species. Two further limacinid species are described as new to science, viz....

Brooding in a temperate zone land snail: seasonal and regional patterns
Provedor de dados: 16
Autores: Sulikowska-Drozd, A.; Maltz, T.K.; Kappes, H.
The goal of this study is to assess if the reproductive strategy of a brooding land snail shifts along a climatic gradient. We focused on the following traits: timing and length of the reproductive season, brood size, ontogenetic dynamics of embryos, and reproductive mode (viviparity versus egg-laying). We dissected the central European door snail Alinda biplicata, collected monthly from eight populations covering the oceaniccontinental climatic gradient within the species’ distribution range. Forty percent of the 1706 dissected individuals were brooding. The species displayed a spring-summer reproductive activity pattern: intrauterine brooding was recorded between March and September; first embryos of a developmental stage that equals that of live-born...

Holoplanktonic Mollusca (Gastropoda: Pterotracheoidea, Janthinoidea, Thecosomata and Gymnosomata) from the Pliocene of Pangasinan (Luzon, Philippines)
Provedor de dados: 16
Autores: Janssen, A.W.
Fifteen samples taken from interbedded sandstone, siltstone and claystone of Pliocene age, underlying the Bolinao Limestone, at the localities Anda, Roxas and Tiep (Pangasinan, Luzon, Philippines), were analysed for holoplanktonic gastropods; they have yielded 50 species (16 Heteropoda, one Janthinidae, and 33 Pteropoda, the latter consisting of 30 Euthecosomata, two Pseudothecosomata and one Gymnosomata). Faunal diversity between the localities sampled is restricted and explained by differences in sample size and/or preservation. The time interval represented by all samples taken together is postulated to have been brief. Fifteen new taxa (= 30% of the total number of encountered holoplanktonic molluscan species) are erected; Atlanta lingayanensis sp....

On the stratigraphic position of the Delden Member (Breda Formation, Overijssel, the Netherlands) with implications for the taxonomy of Pygocardia (Mollusca, Bivalvia)
Provedor de dados: 16
Autores: Bosch, J.; Wesselingh, F.P.
Re-identification of parts of the mollusc fauna of the Delden Member, especially Pygocardia and Panopea species, from the vicinity of Delden (Overijssel prov., the Netherlands) and comparison with other Neogene faunas from the southern North Sea Basin imply a late Early to early Late Pliocene age for the Delden fauna, that usually is attributed to the Miocene. Shell measurements performed for this study revealed that the species definitions for Pliocene North Sea Basin Pygocardia are inadequate.

Autores: Cole, M.L.; Herbert, D.G.
Gulella bruggeni spec. nov., G. bomvana spec. nov., G. tietzae spec. nov. and G. ndibo spec. nov. are described from the Transkei region of Eastern Cape Province, South Africa. All are minute, smooth-shelled species with complex apertural dentition. Due to their limited ranges and continuing decline in extent and quality of habitat, G. bruggeni spec. nov., G. bomvana spec. nov. and G. ndibo spec. nov. are likely to meet the distribution-based criteria for red-listing as Critically Endangered and G. tietzae spec. nov. as Endangered. G. aprosdoketa and G. chi are discussed and illustrated for comparison and the known distribution of each is extended.

Provedor de dados: 16
Autores: Bruggen, A.C. van; Winter, A.J. de.
‘Marconia’ hamiltoni s.l. is known from two discrete mountainous areas in Malawi, i.e. the (southern) Mt. Mulanje complex, and the (more northern) Zomba Plateau s.l. These uplands are separated by about 65 km of lower lying land with different types of vegetation and climate. Material from these two regions may be distinguished as separate species, the southern populations having comparatively small and broad shells with some apertural dentition (‘M’. hamiltoni, lectotype designated), while the northern populations have noticeably larger and more slender shells with a more reduced apertural dentition (‘M’. malavensis). Discussion of the type localities for both taxa shows that these are either localized in an unlikely place (‘M’. hamiltoni) or unclear...

Provedor de dados: 16
Autores: Dance, S.P.
Since 1758, with the publication of Systema Naturae by Linnaeus, thousands of scientific names have been proposed for molluscs. The derivation and uses of many of them are here examined from various viewpoints, beginning with names based on appearance, size, vertical distribution, and location. There follow names that are amusing, inventive, ingenious, cryptic, ideal, names supposedly blasphemous, and names honouring persons and pets. Pseudo-names, difficult names and names that are long or short, over-used, or have sexual connotations are also examined. Pertinent quotations, taken from the non-scientific writings of Gertrude Stein, Lord Byron and William Shakespeare, have been incorporated for the benefit of those who may be inclined to take scientific...

Decline of the Jakarta Bay molluscan fauna linked to human impact
Provedor de dados: 16
Autores: Meij, S.E.T. van der; Moolenbeek, R.G.; Hoeksema, B.W.
In 1937/38 representative mollusc collections were made in Jakarta Bay (West Java, Indonesia). New data from here and the adjacent offshore Thousand Islands archipelago (Kepulauan Seribu) became available in 2005. Although collecting efforts and sampling methods differed, a comparison of the molluscan fauna of Jakarta Bay between 1937/38 and 2005 reveals a distinct deterioration. From 1937 to 2005, Jakarta Bay received increasing amounts of sewage from the greater Jakarta area, as well as increased sediment input from the deforested West Java hinterland. Predatory gastropods and numerous mollusc species associated with carbonate (reef) substrate have vanished from Jakarta Bay, among which many edible species.

Flying high: on the airborne dispersal of aquatic organisms as illustrated by the distribution histories of the gastropod genera Tryonia and Planorbarius
Provedor de dados: 16
Autores: Wesselingh, F.P.; Cadée, G.C.; Renema, W.
The actual and fossil distribution patterns of the aquatic gastropod genera Tryonia and Planorbarius indicate that avian dispersal was an important dispersal mechanism in the geological past. Combining the distribution histories of these genera with ecological data on modern relatives provides insights into the process of dispersal of aquatic taxa in general. Avian dispersal of aquatic taxa is facilitated by a variety of factors, including mass occurrence in resting/foraging places of migrating birds, ways to attach to the birds and to overcome desiccation during flight, as well as easy reproduction from a single specimen when introduced into a new habitat. The uncertain taxonomical status of aquatic organisms, as well as biased preservation and sampling,...

Molluscs from the Miocene Pebas Formation of Peruvian and Colombian Amazonia
Provedor de dados: 16
Autores: Wesselingh, F.P.; Anderson, L.C.; Kadolsky, D.
The mollusc fauna of the Miocene Pebas Formation of Peruvian and Colombian Amazonia contains at least 158 mollusc species, 73 of which are introduced as new; 13 are described in open nomenclature. Four genera are introduced (the cochliopid genera Feliconcha and Glabertryonia, and the corbulid genera Pachyrotunda and Concentricavalva) and a nomen novum is introduced for one genus (Longosoma). A neotype is designated for Liosoma glabra Conrad, 1874a. The Pebas fauna is taxonomically dominated by two families, viz. the Cochliopidae (86 species; 54%) and Corbulidae (23 species; 15%). The fauna can be characterised as aquatic (155 species; 98%), endemic (114 species; 72%) and extinct (only four species are extant). Many of the families represented by a few...

The ecology of shell shape difference in chirally dimorphic snails
Provedor de dados: 16
Autores: Schilthuizen, M.; Haase, M.; Koops, K.; Looijes, S.M.; Hendrikse, S.
The Southeast-Asian tree snail subgenus Amphidromus s. str. (Gastropoda Pulmonata: Camaenidae) is unusual among all gastropods for its genetic antisymmetry: populations consist of stable mixtures of individuals with clockwise (dextral) and counterclockwise (sinistral) coiling directions. Although previous studies in A. inversus suggest that this genetic dimorphism is maintained by sexual selection, it cannot be ruled out that environmental factors also play a role. Adult shell shapes in A. inversus are known to show subtle differences between both coiling morphs, and it is  known that in snails in general, shell shape is under environmental selection, thus creating the possibility that micro-niche use of both coiling morphs differs. In this paper, we first...

Our knowledge concerning taxonomy and zoogeography of the fossil and recent species of the helicid genus Theba is summarized and enlarged. The fossil T. arinagae spec. nov. is described from Gran Canaria. The recent T. andalusica spec. nov. and T. sacchii spec. nov. are described from the southernmost part of the Iberian peninsula and the southernmost part of Morocco, respectively. This implies that four fossil and ten recent Theba species are recognized. Two of the fossil species are very insufficiently known. Some recent species are polytypic, which results in 17 (sub)specific taxa in total. Neotypes are selected for T. subdentata legionaria and T. solimae.

Newly-discovered muscle in the larva of Patella coerulea (Mollusca, Gastropoda) suggests the presence of a larval extensor
Provedor de dados: 16
Autores: Damen, Peter; Dictus, Wim J.A.G.
The development of the muscular system of the gastropod mollusc Patella has been thoroughly studied. As a result, two larval retractors, the main and accessory larval retractor, had been described in the larva of Patella. These muscles were supposed to be responsible for the retraction of the larval body into the shell. Previously no larval extensors, which would be responsible for the extension of the larval body out of the shell, have been described. Using cell-lineage tracer injection and phalloidin staining of muscles, a newly-discovered muscle is herein identified in the larva of Patella coerulea. A functional model is presented in which two muscles are responsible for the extension of the larva, the newly-discovered muscle together with the...

Anatomical evidence for the occurrence of Lymnaea (Galba) palustris (O.F. Müller, 1774) and L. (Galba) corvus (Gmelin, 1778) (Gastropoda: Lymnaeidae) in the Netherlands
Provedor de dados: 16
Autores: Velde, G. van der; Kessel, C.M. van.
A study was made on the Lymnaea (Galba) palustris complex in The Netherlands. Investigations on the genitalia proved that in The Netherlands two species are present, viz. L. palustris (O. F. Müller, 1774) and L. corvus (Gmelin, 1778), which can not in all cases be distinguished by shell characters. Genitalia were prepared, drawn and several measurements were carried out to investigate the variation within the two species. It appeared that most characters show a partial or total overlap. Some characters appeared to separate the two species absolutely. One of these is very useful for a quick distinction of both species, viz. the situation of the truncus receptaculi with respect to the oviductus, which character is already visible after a general dissection...

Autores: Gernet,Marcos de Vasconcellos; Belz,Carlos Eduardo; Baggio,Rafael Antunes; Birckolz,Carlos João; Santos,Elizângela da Veiga; Simone,Luiz Ricardo L.; Abbate,Daniel; Metri,Rafael.
Abstract Exotic species are those that occur in an area beyond their natural limit and they are considered invasive when they cause harm to the economy, environment, or human health. In coastal environments, ballast water and inlays on the hull and other parts of vessels are the main ways of introducing invasive aquatic alien species. Nassarius foveolatus (Dunker, 1847) is native from the Central and East Indian Ocean to the East China Sea. The first specimens (empty shells) of N. foveolatus were collected manually on November 11, 2017 on the Rocio footbridge, located in the Paranaguá Estuarine Complex, on the coast of the State of Paraná, southern Brazil. Posteriorly, live specimens were collected in other localities of this bay. It is already possible to...

HOW DOES HACCP CHANGE U.S. SEAFOOD EXPORTS?-ANALYSIS WITH FISHES, MOLLUSCA, AND SHELLFISH OTHER THAN MOLLUSCA
Provedor de dados: 31
Autores: Li,   Xiaoqian; Saghaian,   Sayed H.
Although the effect of HACCP on international trade is an issue with many concerns recently, only a few empirical studies focus on the impact of HACCP on U.S seafood export industry. Using the approach of Gravity Model with adjustment of unobserved country characteristics, this paper contributes to analyze the differential effects of HACCP implementation on three kinds of seafood: fishes, mollusca, and shellfish other than mollusca. The results indicate that HACCP application has negative but insignificant effect on seafood exports in the short run. In the long run, HACCP only negatively and significantly affect seafood exports of mollusca and shellfish. Moreover, the higher risk of food born disease seafood has, the easier is seafood trading affected by...

Provedor de dados: 103
Autores: Piffer,Pedro Ribeiro; Arruda,Eliane Pintor de; Passos,Flávio Dias.
Macoma biota Arruda &amp;amp; Domaneschi, 2005, is a recently described species known only from the intertidal zone of Praia da Cidade, Caraguatatuba Bay, in the state of São Paulo, southeastern Brazil. The main purpose of the present paper is to describe the biology of M. biota, beginning with a detailed analysis of its anatomy and functional morphology and how these attributes are correlated with its habitat and life history. The morphology of the organs in the pallial cavity and their sorting devices indicate that this species has efficient mechanisms to process large amounts of particles that enter this cavity via the inhalant current. M. biota can rapidly select the material suitable for ingestion and direct the undesired excess to the rejection...

Provedor de dados: 103
Autores: Lacerda,Luiz Eduardo M.; Miyahira,Igor C.; Santos,Sonia B.
The freshwater snail Gundlachia ticaga (Marcus &amp;amp; Marcus, 1962) is widely distributed in Brazil, but its morphology has been poorly studied. We compared the shell morphology of samples from four sites (Vila do Abraão, Vila de Provetá, Parnaioca and Praia do Sul) in Ilha Grande (Angra dos Reis, state of Rio de Janeiro) in order to evaluate differences within and among four populations. We used nine morphometric characters representing shell size and shape. To analyze shell morphology we considered aperture shape, sculpture of teleoconch, apex carving and position. The resulting dataset was correlated by Pearson´s linear correlation and shell differences among populations were tested using ANOVA and Discriminant Function Analysis. The results showed...

First record of Thylaeodus (Gastropoda: Vermetidae) from the Equatorial Atlantic Ocean, with the description of a new species
Provedor de dados: 103
Autores: Spotorno,Paula; Simone,Luiz Ricardo L.
The vermetid Thylaeodus equatorialis sp. nov. is endemic to the São Pedro and São Paulo Archipelago, located at the mid equatorial Atlantic Ocean. The species is closely related to Thylaeodus rugulosus (Monterosato, 1878), as indicated by similar shell characters, coloration of the soft parts, and feeding tube scars. However, T. equatorialis sp. nov. mainly differs from T. rugulosus in the operculum/aperture diameter ratio (~79% versus 100%), by having well developed pedal tentacles and fewer egg capsules in brooding females. In addition, the new species has the following unique characteristics: size almost twice as large (shell, tube aperture, erect feeding tube, protoconch and egg capsules) as the other Atlantic species; unusual method of brooding egg...

The digestive gland of Phyllocaulis soleiformis is a compound tubular gland. The secretory tubules are made up of two main cell types: the digestive cells and calcic cells. The digestive cells are the most numerous, usually columnar, and exhibit three different functional stages: absorptive, secretory and excretory. These cells contain two cytoplasmic granules types and, in the excretory stage, most of the cell is occupied by a large vacuole. The calcic cells occursingly or frequently in groups of two or three, are triangular shaped and have distinct apical granules, and yet calcic histochemical detected granules. In addition, there is a third cell type, without characteristic cytoplasmic granules and which correspond to the undifferentiated cells. The...

Autores: Santos,Marco Antonio Vasconcelos; Diniz,José Antonio Picanço.
Os hemócitos do caramujo Biomphalaria glabrata, um importante transmissor do trematódeo Schistosoma mansoni no Brasil, foram coletados de especimens na região Bragantina, localizada a oeste do estado do Pará. Os hemócitos foram examinados por meio de microscopia eletrônica de transmissão. As células foram fixadas pelo método de rotina com o uso do tampão PHEM (PIPES, HEPES, EGTA e Magnésio). Foram descritos os aspectos ultra-estruturais celulares como inclusões citoplasmáticas limitadas por membranas, mitocôndrias, retículos endoplasmáticos e outros. As observações mostram que esse tampão possui a propriedade de preservação do citoesqueleto celular, apresentando bons resultados na preservação das estruturas dos hemócitos e suas organelas.

The first finding of Ostrea cf. puelchana (Bivalvia) living as epibiont on Callinectes exasperates (Decapoda)
Provedor de dados: 3
Autores: Lima, Silvio Felipe Barbosa; Lucena, Rudá Amorim; Queiroz, Vinicius; Guimarães, Carmen Regina Parisotto; Breves, André.
 This paper describes the epibiosis of Ostrea cf. puelchana on Callinectes exasperatus (Gerstaecker, 1856), both collected from the estuary of the Paraíba River, in the state of Paraíba, northeastern Brazil. The basibiont crab was captured using a trap installed in mangrove area at a depth of about 2 meters. The oyster was closely attached to the left side of dorsal carapace covering most of the epibranchial, mesobranchial and metabranchial regions. Possible advantages and disadvantages for both the epibiont and the basibiont are discussed. We believe that young O. cf. puelchana may avoid a variety of potential predators due to the considerable movement capacity of C. exasperatus and may also serve as a small protective shield for the basibiont. However,...

El Género Nodipecten Dall (Bivalvia, Pectinidae) en el Neógeno de la Patagonia (Argentina)
Provedor de dados: 41
Autores: del Río,Claudia J.
El registro más antiguo del género Nodipecten Dall corresponde al Mioceno temprano alto, momento durante el cual tuvo, de acuerdo al registro fosilífero conocido hasta el momento, una distribución discontinua sobre el litoral atlántico occidental, registrándoselo en Patagonia y en la región caribeña. A fines del Mioceno medio se extinguió en Patagonia y desde entonces permaneció restringido a las latitudes tropicales del continente americano hasta hoy, expandiéndose al área tropical del Pacífico oriental en el Mioceno tardío. Su asociación a taxones paratropicales en Patagonia indica el desarrollo de aguas cálido-templadas en la región, reflejando el Óptimo Climático del Neógeno y su extinción en la región y su retracción a latitudes tropicales coincidió...

Molluscan assemblages from the marine Holocene of Uruguay: composition, geochronology, and paleoenvironmental signals
Provedor de dados: 41
Autores: Martínez,Sergio; Rojas,Alejandra; Ubilla,Martín; Verde,Mariano; Perea,Daniel; Piñeiro,Graciela.
Dates of marine Holocene molluscs from Uruguay (Villa Soriano Formation) range from 6849 to 1858 cal. years BP. There are no significative gaps among the different ages obtained, with the exception of the interval 2276-2830 calculated years BP. Two kinds of concentrations are distinguished: autochthonous, for which a low energy depositional environment is inferred, and parautochthonous, deposited in foreshore and nearshore high-energy environments. Results of different types of multivariate analyses on presence-absence and abundance data show that only three localities are clearly differentiated from the others. The discrimination of two of them (Arazatí, Las Cañas) is explained by the presence of only one or two species, but the third (Punta Rasa) is the...

Análisis tafonómico de quitones (Polyplacophora: Mollusca) holocenos de Tierra del Fuego, Argentina
Provedor de dados: 41
Autores: Gordillo,Sandra.
En el Holoceno marino de Tierra del Fuego los quitones representan una fracción menor dentro de las asociaciones de moluscos, principalmente formadas por bivalvos y gastrópodos. En este trabajo se analizan las razones de su escasa abundancia relativa. El análisis de sus atributos tafonómicos y paleontológicos indica que la condición tafonómica de una placa de quitón es el resultado de una combinación de factores biológicos, ecológicos y ambientales. Se concluye que los quitones constituyen buenos indicadores paleoecológicos y paleoambientales, ya que mantienen fidelidad ecológica respecto a las paleocomunidades de las cuales derivan, y también permiten evaluar los procesos post-mortem ocurridos hasta su descubrimiento.

Abstract: Coastal ecosystems of northeastern Brazil have important biodiversity with regard to marine mollusks, which are insufficiently studied. Here we provide an inventory of mollusks from two sites in the estuary of the Paraíba River. Mollusks were collected in 2014 and 2016 on the coast and sandbanks located on the properties of Treze de Maio and Costinha de Santo Antônio. The malacofaunal survey identified 12 families, 20 genera and 21 species of bivalves, 17 families, 19 genera and 20 species of gastropods and one species of cephalopod. Bivalves of the family Veneridae Rafinesque, 1815 were the most representative, with a total of five species. Gastropods of the family Littorinidae Children, 1834 had the greatest species richness. The most abundant...

First record of Melanoides tuberculatus (Müller, 1774) and Biomphalaria tenagophila (d´Orbigny, 1835) on Ilha Grande, Rio de Janeiro, Brazil
Provedor de dados: 49
Autores: Santos,Sonia Barbosa dos; Miyahira,Igor Christo; Lacerda,Luiz Eduardo Macedo de.
Small populations of Melanoides tuberculatus (Müller, 1774) and Biomphalaria tenagophila (d´Orbigny, 1835), were found at Vila do Abraão, being the first record of these species to Ilha Grande, Angra dos Reis, Rio de Janeiro. They were probably introduced after 2004, perhaps following release from aquaria. The possible spread of these species to other freshwater habitats in the island, their effects on native snails and links with public health are discussed. The record of M. tuberculatus appears to be the first for a Brazilian insular area. The recent introduction of these species offers a remarkable opportunity to monitor introduced species and to understand the invasion process in an insular stream in southeastern Brazil.

Provedor de dados: 52
Autores: Viana,Marina Gomes; Rocha-Barreira,Cristina de Almeida.
Adult animals of Spondylus americanus were analyzed and specialized sensorial structures, the sensorial papillae and the eyes, were characterized. The sensorial papillae were projections on the edge of the mantle in form of light brown fingers which had function of percepting stimulus coming from the medium. They were constituted by loose conjunctive tissues with longitudinal muscular fibers and externally covered by ciliated cubic epithelium, which presented high amount of melanocytes that gave the coloration of the papillae. The eyes were more complex, being on small stalks histologically similar to the papillae. They exhibited a circular formate and had a metallic blue color. Theses structures were constituted by a corneo epithelium, cornea, lens,...
