CHILEAN MARINE MOLLUSCA OF NORTHERN PATAGONIA COLLECTED DURING THE CIMAR-10 FJORDS CRUISE
Provedor de dados: 72
Autores: Cárdenas,Javiera; Aldea,Cristian; Valdovinos,Claudio.
The tip of the South American cone is one of the most interesting Subantarctic areas, both biogeographically and ecologically. Nonetheless, knowledge of the area's biodiversity, in particular that of the subtidal marine habitats, remains poor. Therefore, in 2004, a biodiversity research project was carried out as a part of the cruise Cimar-10 Fjords, organized and supported by the Chilean National Oceanographic Committee (CONA). The results of the subtidal marine mollusk surveys are presented herein. The samples were collected aboard the Agor 60 "Vidal Gormaz" in winter 2004. The study area covered the northern Chilean Patagonia from Seno de Relocanví (41°31'S) to Boca del Guafo (43°49'S), on the continental shelf from 22 to 353 m depth. The Mollusca were...

MORPHOLOGICAL AND ANATOMICAL FEATURES OF FLAMMULINA FESTIVA SCOTT, 1970 (STYLOMMATOPHORA; CHAROPIDAE) FROM SOUTHERN CHILE, WITH NOTES ON ITS NATURAL HISTORY
Provedor de dados: 72
Autores: Cádiz,Francisco J; Gallardo,Carlos S.
Flammulina festiva Scott, 1970 is a terrestrial gastropod endemic to southern Chile. Characteristics of living specimens, including the anatomy of the excretory and reproductive systems of this species are here reported for the first time. The excretory system of this species is of the charopid type with a short, curved primary ureter, and a secondary ureter which extends to the excretory sinus. The reproductive system exhibits characteristics similar to other Charopidae. There is an ovotestis that is divided into seven lobes, a well-developed albumin gland, an ovospermial duct with a proximally diverticulate, distally undivided prostatic gland, plus a short oviduct. The terminal portion of the system shows a pointed epiphallus, and a phallus within a...

Provedor de dados: 76
Autores: Sant'Anna,Bruno S.; Zangrande,Cilene M.; Reigada,Alvaro L. D.; Pinheiro,Marcelo A. A.
We evaluated the gastropod shell utilization pattern of the hermit crab Clibanarius vittatus (Bosc, 1802) at Pescadores Beach in São Vicente, State of São Paulo, Brazil. Specimens were collected monthly from May 2001 through April 2003, in the intertidal zone at low tide. The crabs were weighed and their carapace shield length measured. All gastropod shells were identified and had their shell biometric parameters (total length and aperture length) measured (mm) and weighed (g). A total of 2,344 hermit crabs (644 males, 1,594 females, 45 ovigerous females and 61 individuals in intersex), using 13 species of gastropod shells, were collected. Stramonita haemastoma (Linnaeus, 1767), Cymatium parthenopeum (Von Salis, 1793) and Achatina fulica (Bowdich, 1822)...

Preliminary biological characterization of the Saldanha hydrothermal field at the Mid-Atlantic Ridge (36 degrees 34 ' N, 32 degrees 26 ' W, 2200 m)
Provedor de dados: 5
Autores: Biscoito, M; Almeida, A; Segonzac, Michel.
A preliminary description of the biology of the Saldanha hydrothermal field in the Mid-Atlantic Ridge (36 degrees 34'N, 32 degrees 26'W, 2200 m) is given, based on direct observation, video images and samples. Venting occurs mainly in a diffuse way through sediment, but hydrothermal fluid discharges are visible through centimeter-long orifices, scattered on the sediment, over an area of approximately 400 m(2), at depths between 2,200 and 2,220 metres. Emitted fluids are transparent, with a temperature of 7-9 degrees C. An almost complete absence of macro- and megafauna around the venting orifices was found. The only vent invertebrate identified was the gastropod Phymorhynchus sp., with only two juvenile specimens caught. A careful examination of the images...

Cymatium corrugatum (Lamarck 1816) Gastropoda, Prosobranchia. A new species for the adriatic
Provedor de dados: 5
Autores: Simunovic, A.
Very valuable papers concerning malacology of the Adriatic Sea deal, for the most part, with the systematics, whereas there is a substantial number of papers with very scarce information on the ecology of individual species. Since I intended to provide some more comprehensive data on individual species, rather complex bionomic and biocoenological research was undertaken aiming to study the taxonomy and the ecology of the Prosobranchiata group. Present research covered different biotopes of the northern, middle and southern Adriatic, both in the shallow coastal and deeper open littoral, and hard and mobile bottoms. Material was collected in two ways: 1) Scuba diving or direct collection and observations; and 2) an indirect method of collection of samples by...

Donnees sur les gasteropodes dulcicoles de l'ouest de la France: Mise en evidence de cinq groupes d'especes (ACP)
Provedor de dados: 5
Autores: Costil, F.
24 Species of Gastropoda, representing 3357 specimens, have been sampled in 57 varied ponds of Brittany (France). The most frequent species (at least in 10% of the samples) are considered according to their average abundance and dominance. The average specific richness of the ponds where the species have been collected is studied. In a second stage, the Gastropoda are analysed by means of a principal component analysis. The 1-2 plane correspond to 87% of the whole variance. This analysis associated with a cluster analysis led to the partition of 5 groups of species.

Modelisation bioeconomique de la pecherie de buccin (Buccinum undatum L.: Gastropoda) du port de Granville (Manche ouest). Elements de gestion de la ressource.
Provedor de dados: 5
Autores: Santarelli, L; Gros, Philippe.
The totality of French landings of whelk (Buccinum undatum L.) is assignable to the fisheries of the Normand-Breton Gulf, western Channel. The aim of this paper is to forecast economic rent of the potters of the harbour of Granville, as a function of the two main variates open to supervision: the size of the fishing fleet, and the number of whelk-pots per ship. In order to assess the biological and financial consequences of a prospective development, a deterministic model of the fleet-resource system is proposed. Results of simulations emphasize the sharpness of the rent-dissipation problem under existing tendencies. Therefore some recommendations are put forward to derive a fishery policy that would enable the system to be maintained near optimal...

A model of fluff layer erosion and subsequent bed erosion in the presence of the bioturbator, Hydrobia ulvae
Provedor de dados: 5
Autores: Orvain, Francis; Le Hir, Pierre; Sauriau, Pierre-guy.
Previous studies have shown that the gastropod Hydrobia ulvae destabilizes the top layers of fine-grained sediments. This process is mediated by the formation of a "biogenic" fluff layer that includes tracks, faecal pellets and mucus. This fluff layer has been shown to be easily resuspended before general bed erosion. In order to examine how fluff layer and bed. erosion interact, flume experiments were performed with fluid sediments of varying water contents. Ten thousand snails were placed and allowed to crawl for 5 h on the sediment surface, and then the resuspended sediment mass was measured in response to step-wise shear stress increases. Two distinct erosion phases were observed: (1) initial resuspension of the fluff layer and (2) the subsequent bed...

Autores: Ramesh, A; Venugopalan, V.
Information available on the association of luminous bacteria with marine invertebrates is limited. Hence qualitative and quantitative investigations were undertaken with a view to understand the distribution of luminous microflora in relation to the environmental factors and also in the gut of two marine gastropods, Aplysia benedicti Eliot and Bullia tranquebarica (Roding) from Porto Novo (11 degree 29'N, 79 degree 46'E) waters of the East coast of India. The gut of the gastropods harboured maximum number of luminous bacteria when compared to the water and sediment. Qualitative analysis revealed the presence of two luminous bacterial components, viz. Vibrio harveyi and V. fishceri. V. fischeri was not found in association with A. benedicti . The isolates...

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...

Sanitation with sponge and plunger: western Atlantic slit-wormsnails (Mollusca : Caenogastropoda : Siliquariidae)
Provedor de dados: 5
Autores: Bieler, R.
Siliquariid Tenagodus (synonym: Siliquaria) snails are obligatory sponge commensals, with uncoiling and laterally slitted shells embedded inside Demospongiae hosts, and shell apertures facing the outside allowing for respiratory and gill-filter-feeding activities. Live-collected animals observed in situ within hosts provide the first detailed functional morphological study of the group, and form the basis for systematic revision of the western Atlantic members of type genus Tenagodus (Siliquariidae, synonym: Tenagodidae). Three species are recognized. Overall anatomical features of wide-ranging Atlantic T. modestus (Dall, 1881) and T. squamatus (de Blainville, 1827) [ = T. anguillae Morch, 18611 are similar to those previously described for New Zealand...

On altitude dependent characters in Albinaria idaea (L. Pfeiffer, 1849), with a revision of the species (Gastropoda Pulmonata: Clausiliidae)
Provedor de dados: 16
Autores: Engelhard, G.H.; Slik, J.W.F.
Several forms of Albinaria idaea (L. Pfeiffer, 1849) have been described as (sub)species from various sites on Mt. Ida (Central Crete). In recent years, however, much additional material has been collected, which made clear that no sharp boundaries exist between these forms. Moreover, several characters proved to be altitude dependent to a certain extent. It may be concluded that on Mt. Ida only a single evolutionary entity can be distinguished, viz. A. i. idaea. On the isolated Mt. Kedros, south-west of Mt. Ida, an undescribed allopatric form was found, which because of its smaller size and differences in altitude dependent characters was given subspecific rank as A. i. amabilis ssp. nov. On the Paximadia Isles, south of Central Crete, a percostate and a...

An isolated gastropod homing scar, etched into an arcoscalpelline (cirripede) scutum, is recorded from the upper Nekum Member (Maastricht Formation, upper Maastrichtian) at the ENCI-HeidelbergCement Group quarry. This trace may be assignable to the ichnogenus Lacrimichnus Santos, Mayoral &amp; Muñiz, that comprises etching scars produced by Neogene calyptraeid and/or capulid gastropods and ostreid bivalves from southern Spain and Portugal. However, it differs from both ichnospecies currently contained in that ichnogenus, L. bonarensis and L. cacelensis, in showing a relatively deep depression around the rim, irregularly distributed pit- and slit-like depressions, and an irregularly subcircular outline.

The Arion Hortensis complex (Pulmonata: Arionidae): designation of types, descriptions, and destributional patterns, with special reference to the Netherlands
Provedor de dados: 16
Autores: Winter, A.J. de.
A lectotype of Arion hortensis Férussac, 1819 and a neotype of A. distinctus Mabille, 1868 are selected in order to assure nomenclatural stability. Descriptions of preserved specimens of these species from large parts of central and western Europe are provided, as well as of living animals from The Netherlands and Belgium. The main characters used by Davies (1977, 1979) to separate the British representatives of this complex were found suitable in the rest of Europe as well, in contrast to some characters given by De Wilde (1983). Arion owenii Davies, 1979 was not present in the material studied. Provisional UTM-distribution maps (50 km grid) of A. hortensis and A. distinctus in Europe (except the British Isles and Belgium) are provided, besides 10 km grid...

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)
Provedor de dados: 16
Autores: Mead, A.R.
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.  Change, and therefore...

Provedor de dados: 16
Autores: Breure, A.S.H.; González Guillén, A.
This paper presents a comprehensive overview of literature on Cuban terrestrial molluscs since the 18th century. It currently cites approximately 1000 references, dealing with a) primary and secondary sources directly treating Cuban taxa or relevant for the study of the Cuban malacofauna; b) abstracts of congresses, unpublished theses, and internal reports ('grey literature'); and c) biohistorical papers dealing with the life and work of Cuban malacologists. To provide some context, we also give brief overviews of Cuban and non-Cuban authors and journals issued on the island relevant for Cuban malacology.

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...

Frustrating facts about area cladistics and species individuality
Provedor de dados: 16
Autores: Gittenberger, E.
Area cladistics suffer from the fact that areas have various “histories”, as such dictated by different groups of taxa. Consequently, a generalized area cladogram has not or hardly any biological meaning. Conflicting area cladograms may be derived from even the same species, when their ranges in different geological periods are used. This is a consequence of the individuality of species.

Slug assemblages in NW Germany (Gastropoda: Milacidae, Boettgerillidae, Limacidae, Agriolimacidae, Arionidae): a result of the mapping survey of Northrhine-Westphalia.  This survey provides information on inter-specific associations of slugs on a regional data base. Most of the data originate from the last ten years. In total, 25 slug species are known from the federal state Northrhine-Westphalia, Germany. A rough classification using two character species resulted in three groups. These groups correspond to habitat preferences, i.e. species that are regularly found together with Arion rufus usually occur in close-canopy forests and mid-successional stages, species that are regularly found together with Arion lusitanicus prefer open habitats to...

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

Studies on the Streptaxidae (Mollusca: Gastropoda Pulmonata) of Malawi 12 Four new species of Gulella s.l.
Provedor de dados: 16
Autores: Bruggen, A.C. van.
Gulella annibiodiversitatis spec. nov. is described from a few scattered localities in montane forest above c. 1300 m in southern-central Malaŵi. It is mainly characterized by a smallish (4.9-6.3 mm high), smooth and generally featureless shell without apertural dentition. Gulella menkhorsti spec. nov., has a small (2.3-2.9 mm high) and smooth shell with a six-fold dentition and is probably a restricted range endemic; so far it has only been recorded from the Mpita Forest in southern Malaŵi. A single smooth and small shell (2.7 mm) with a seven-fold apertural dentition from the Misuku Hills in northern Malaŵi also does represent a new species, Gulella crux spec. nov. Another sample from the same area, introduced as Gulella nuchalis spec. nov., has a...

Hummelinckiella borinquensis, a new genus and species in the subfamily Stephopominae (Caenogastropoda: Siliquariidae) with notes on the genera Caporbis and Stephopoma and the “Blasian subregion”
Provedor de dados: 16
Autores: Faber, M.J.; Moolenbeek, R.G.
A new genus and species, Hummelinckiella borinquensis n.gen. &amp; n.sp. has been discovered in sediments from shallow water off Puerto Rico, the Dominican Republic, and Grand Turk (Turks &amp; Caicos Islands). Because of the striking sculpture of its protoconch, it is placed in a new genus of the subfamily Stephopominae. The only other known western Atlantic member of the Stephopominae is Stephopoma myrakeenae Olsson &amp; McGinty, 1958 recorded from the eastern Caribbean (Leeward Islands), herewith invalidating the “paciphile” status of this species and genus, and casting doubts on the value of the “Blasian Subregion”, indicated by Petuch (1990) as a biogeographical unit.

Pteropods (Mollusca, Euthecosomata) from the Early Eocene of Rotterdam (The Netherlands)
Provedor de dados: 16
Autores: Janssen, A.W.
A borehole was drilled at Rotterdam in 1955 as a demonstration during the E55 exhibition. Holoplanktonic molluscs (pteropods) were found to be present in the interval 504.5-655.0 m below rotary table (= RT). 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....

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...

Autores: Kabat, A.R.
The 1990 Rumphius Biohistorical Expedition to Ambon (Indonesia) made 44 collecting stations. Twenty-seven species representing 11 genera of the Naticidae (Gastropoda: Caenogastropoda) were collected at 29 stations. This paper provides keys to the genera and species, along with diagnoses and short synonymies of the species. The modern identity of the thirteen naticid species known to Rumphius in his “D’Amboinsche Rariteitkamer” (1705) is determined. Fifty described species of Naticidae are currently known from Malaysia and Indonesia, with 38 known from Ambon itself (this expedition and older museum collections).

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: Bruggen, A.C. van.
Gulella adami spec. nov. is described from a classical West African locality, Assini in the Ivory Coast (Côte d'Ivoire). It is most unusual in showing two superficial parietal processes, which may also be interpreted as a double angular lamella, in the aperture of the shell. The shell closely resembles that of various Enidae in SE Europe and adjoining areas around the Mediterranean, thereby providing a striking example of convergent evolution.

On the basis of both detailed distributional field studies and morphological analyses, a revision of the polytypic species Albinaria hippolyti from Central and Eastern Crete is presented. True subspecies are distinguished from mere geographic varieties by the presence of narrow hybrid zones. Using this criterion, four adjoining subspecies are recognised: A. h. hippolyti (Boettger, 1878), A. h. aphrodite (Boettger, 1883), A. h. holtzi (Sturany, 1904) and A. h. harmonia subspec. nov. Additionally, two geographically isolated and conchologically distinctive forms are also treated as subspecies: A. h. arthuriana (Boettger, 1878) and A. h. asterousea subspec. nov.

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,...

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...

They belong to three genera, Bostryx, Neopetraeus and Scutalus. It is hypothesized that carination originated independently in these lineages.

Provedor de dados: 16
Autores: Gittenberger, E.; Goud, J.
Taxonomic and biogeographic data on Babylonia and Zemiropsis, published after the 1981 monograph on Babylonia by Altena &amp; Gittenberger, are summarized and new data are added. Babylonia and Zemiropsis are characterized and considered most closely related genera. Babylonia lani spec. nov. and Babylonia umbilifusca spec. nov. are introduced as new to science. Babylonia leonis Altena &amp; Gittenberger, 1972, described from pliocene-pleistocene deposits, is reported as an extant species. The enigmatic “Babylonia” rosadoi is considered a Zemiropsis species on the basis of both shell morphology and distribution.

Fossil predation: did some clavilithine fasciolariid gastropods employ valve-wedging to feed on bivalves?
Provedor de dados: 16
Autores: Vermeij, Geerat J.
Several gastropods, including members of the  Busyconinae, wedge or chip bivalve prey by inserting the  outer lip between the valves. This habit, which is associated  with an abapically downwardly convex outer lip, often results  in breakage and subsequent repair of the lip. I tested the  hypothesis that convex-lipped clavilithines from the Eocene  of France and the Neogene of Indonesia had higher frequencies  of repair than their straight-lipped counterparts. Although  this prediction was verified, frequencies of repair are low (0  to 0.19) compared to those of busyconines, indicating either  that prey bivalves were small or that the predators are smaller  than most busyconines.

Notes on Micractaeon, a monotypic genus of African land snails (Gastropoda Pulmonata: Ferussaciidae?)
Provedor de dados: 16
Autores: Bruggen, A.C. van; Winter, A.J. de.
Micractaeon kakamegaensis Verdcourt, 1993 (type loc. Kenya, Kakamega Forest), is a synonym of Pseudopeas koptawelilense Germain, 1934 (type loc. Kenya, Mt. Elgon); the proper name is therefore Micractaeon koptawelilensis (Germain, 1934). New anatomical data are supplied, more or less confirming classification in the family Ferussaciidae. The shell is subject to some considerable variation in size, shape and sculpture. The species appears to be widely distributed in various types of forest in tropical Africa (Ghana, Cameroon, eastern and south-eastern Zaïre, Kenya, Malawi, and eastern Zambia); hypsometrical distribution is generally from c. 950 m to c. 2300 m, although in Ghana it has been collected at altitudes of between &amp;lt; 250 and c. 700 m.

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...

Studies on the Streptaxidae (Mollusca: Gastropoda Pulmonata) of Malawi9. Description of Gulella streptostelopsis, a new Streptostele-like species of Gulella.
Provedor de dados: 16
Autores: Bruggen, A.C. van.
Gulella streptostelopsis spec. nov. is described from a series of localities of mainly between 1000 and 1500 m a.s.l. in Malawi south of about 11°S. The minute, almost smooth, shell (length 2.0-2.4 mm) resembles that of the genus Streptostele (hence the name), but is characterized by three-fold apertural dentition and just under six whorls. This taxon may represent a new genus; pending studies on the anatomy no new generic name is proposed.

Abstract The malacofauna bycatch of sea-bob shrimp Xiphopenaeus kroyeri (Heller, 1862) trawl fisheries on the coast of Sergipe was studied for 5 years. The malacofauna bycatch considered was obtained in nine oceanographic sampling campaigns carried out between May 1999 and June 2003 in 18 stations distributed in six transects along depths of 10, 20 and 30 m. A total of 2,669 individuals of mollusk belonging to 54 species were captured on the 18 sea-bob shrimp trawl stations carried out along the coast of Sergipe. The considerable richness of mollusks was composed by 19 families and 31 species of gastropods, 12 families and 19 species of bivalves and 2 families and 4 species of cephalopods. The highest abundance were observed at stations 13 (373...

Redescription of Ventania avellanedae (Stylommatophora: Odontostomidae), a land snail endemic to the Ventania Mountain System, Argentina
Provedor de dados: 103
Autores: Pizá,Julia; Cazzaniga,Néstor J.; Ghezzi,Natalia S.
ABSTRACT Although the presence of apertural folds and lamellae is the most recognizable character of the Odontostomidae, some species lack them, mostly in Anctus Martens, 1860, Bahiensis Jousseaume, 1877 and Moricandia Pilsbry &amp; Vanatta, 1898. Eudioptus avellanedae Doering, 1881 - a slender odontostomid species that lacks even the slightest trace of folds or lamellae in its shell aperture - was however transferred to Odontostomus by Pilsbry in 1902 on the basis of its building forward of the aperture-margins. It is currently placed in its own monotypic subgenus, Cyclodontina (Ventania) Parodiz, 1940, on the basis of about the same argument. In this paper we redescribe its shell morphology and, for the first time, describe the internal anatomy of the...

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...

Locomotion of Stramonita haemastoma (Linnaeus) (Gastropoda, Muricidae) on a mixed shore of rocks and sand
Provedor de dados: 104
Autores: Papp,Marcos G.; Duarte,Luiz F.L.
Mixed shores of rocks and sand are appropriate systems for the study of limitations that the isolation of rocks may impose for gastropods that typically inhabit rocky shores. We marked 52 Stramonita haemastoma (Linnaeus, 1767) snails on a mixed shore and found that 34 of them moved between rocks one to four times during 15 surveys in a period of 72 days. In the experiments, the snails moved on rock by continuous, direct, ditaxic, alternate undulations of the foot sole but on submerged sand they used slower arrhythmic discontinuous contractions of the foot sole. They switched between modes of locomotion in response to the type and topography of the substrate and possibly to water dynamics. In nature, snails moved between rocks forming aggregations where...

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...

Addisonia enodis (Vetigastropoda: Lepetelloidea) associated with an elasmobranch egg capsule from the South Atlantic Ocean and the discovery of the species from deep waters off northeastern Brazil
Provedor de dados: 49
Autores: Lima,Silvio Felipe Barbosa; Simone,Luiz Ricardo Lopes; Guimarães,Carmen Regina Parisotto.
Abstract A gastropod specimen of the subfamily Addisoniinae Dall, 1882 is reported here for the first time associated with an elasmobranch egg capsule from the South Atlantic Ocean. A specimen of Addisonia enodis Simone, 1996 was found living inside an egg capsule of Atlantoraja castelnaui (Miranda Ribeiro, 1907) (Arhynchobatidae Fowler, 1934) from shallow waters off southeastern Brazil. Previous studies have reported the association of members of the genus Addisonia Dall, 1882 only with the egg capsules of sharks from the family Scyliorhinidae Gill, 1862 and skates from the family Rajidae de Blainville, 1816. Other specimens of A. enodis are also here reported to occur off northeastern Brazil based on shells found in deep waters off the state of Sergipe,...

Autores: Lima,Silvio Felipe Barbosa; Lucena,Rudá Amorim; Santos,Galdênia Menezes; Souza,José Weverton; Christoffersen,Martin Lindsey; Guimarães,Carmen Regina; Oliveira,Geraldo Semer.
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...

Occurrence of Naididae (Annelida: Oligochaeta) from three gastropod species in irrigation fields in southeastern Brazil
Provedor de dados: 49
Autores: Martins,Renato Tavares; Alves,Roberto da Gama.
In the present study we report the occurrence of three Naididae species from three gastropod mollusk species. The species Dero (Dero) righii was found from mollusks of the genus Biomphalaria. Nais communis was found from Biomphalaria sp. and Aplexa rivalis. Chaetogaster limnaei was found from Biomphalaria sp., Aplexa rivalis and Lymnaea columella. In Brazil, previous studies have reported the occurrence of Chaetogaster limnaei from Biomphalaria solely, while Nais communis have been found from Pomacea bridgesii and Dero (Dero) righii in the sediment of aquatic habitats in Mato Grosso do Sul. Our results indicate that, due to their locomotion, naidids are capable of colonizing different substrates in aquatic environments.

On the oviposition and egg masses of Conus regius (Neogastropoda: Conidae) from northeastern Brazil
Provedor de dados: 49
Autores: Gonçalves,Pricila Bento; Lima,Silvio Felipe Barbosa; Oliveira,Geraldo Semer Pomponet; Lucena,Rudá Amorim.
Abstract Characteristics of the egg masses of Conus regius Gmelin, 1791 are described and figured for the first time for the coast of Brazil based on a female specimen found in the process of oviposition during the day in the state of Bahia, northeastern Brazil. Two clusters of egg masses were found in the subtidal zone of Itapuã beach attached to rocky substrate in a completely unprotected site. Oviposition likely began at least one day earlier, since the specimen had already affixed an entire egg mass and was ovipositing a second cluster at the time it was found. The egg masses were arranged in short, irregular rows of three to nine closely spaced capsules in parallel and facing the same direction. One egg mass cluster consisted of 34 capsules. Conus...

Abstract: The reef ecosystems of Morro de São Paulo are located in the Tinharé-Boipeba Environmental Preservation Area which was established in 1992 in the state of Bahia, Brazil. Despite this area has been created more than two decades ago, no study has provided knowledge on the invertebrate biodiversity associated with such reef ecosystems. The present investigation provides the first inventory of benthic mollusks associated with the reef ecosystems of Morro de São Paulo based on the collection of living specimens and fresh empty as well as some worn shells. Mollusks were sampled in January 2015 and August 2016 through intensive searches from the intertidal to shallow subtidal habitats of the reefs on three beaches of Morro de São Paulo. Taxonomic...

Autores: Zanol,Joana; Fernandez,Monica Ammom; Oliveira,Ana Paula Martins de; Russo,Claudia Augusta de Moraes; Thiengo,Silvana Carvalho.
O caramujo africano invasor Achatina fulica foi introduzido no Brasil a partir de Estados do Sul e Sudeste em pelo menos três ocasiões. Atualmente sua distribuição já abrange 24 dos 26 estados e o Distrito Federal. Populações densas dessa espécie vêm causando incômodos à populações humanas, danos à jardins e pequenas plantações, além de atuarem como transmissoras de duas zoonoses (angiostrongilíase abdominal e meningoencefalite eosinofílica) e outras parasitoses de interesse veterinário. No presente estudo, apresentamos novas ocorrências de A. fulica no Estado do Rio de Janeiro (Brasil) assim como dados sobre as larvas de nematódeos de interesse médico e veterinário encontradas em exemplares dessa espécie coletados neste estado.

Abstract: The pronounced dry season determines the characteristics of the semiarid region of Brazil. Numerous small reservoirs are built to overcome this condition, accumulating multiple uses and causing important changes in the landscape and the local biota. Considering the limited amount of information about the malacofauna of reservoirs, mainly in the Northeast region of the country, this inventory provides a list of mollusks from three important reservoirs located in the city of São Julião, state of Piauí. The collections were carried out monthly between May/2017 and April/2018, sampling a total of 11,149 mollusks, corresponding to the species Melanoides tuberculata (Müller, 1774) (n = 9,724), Biomphalaria straminea (Dunker, 1848) (n = 1,361) and...

EXPLOTACIÓN, USOS Y ESTADO ACTUAL DE LA CIGUA O BURGAO CITTARIUM PICA (MOLLUSCA: GASTROPODA: TROCHIDAE)EN LA COSTA CONTINENTAL DEL CARIBE COLOMBIANO
Provedor de dados: 50
Autores: Osorno Arango,Adriana; Díaz Merlano,Juan M.
La cigua o burgao, Cittarium pica es un gasterópodo común y conspicuo de la zona intermareal del litoral rocoso del Caribe y ha sido utilizado como alimento por el hombre desde tiempos precolombinos. Aunque la extracción del recurso es realizada únicamente por pescadores artesanales y principalmente para autoconsumo de pobladores locales, su abundancia se ha visto reducida notablemente durante los últimos diez años, por lo que la especie hace parte de la lista roja de fauna amenazada en varios países caribeños, incluido Colombia. El presente estudio tuvo por objeto hacer un diagnóstico del estado actual de la población de C. pica a lo largo de la costa continental del Caribe colombiano, así como una caracterización general de los niveles de explotación y...

Biogeographic and species richness patterns of Gastropoda on the southwestern Atlantic
Provedor de dados: 57
Autores: FLOETER,S. R.; SOARES-GOMES,A.
Patterns of richness and biogeography of Gastropoda molluscs were determined based on lists of species from five sites along the southwestern Atlantic. The analysis of the distribution patterns of these sites confirmed the existence of a broader transition zone between southern Espírito Santo State (21°S) and Rio Grande do Sul State (32°S). This zone is very heterogeneous, presenting a low endemism rate and a significant number of species common to the near provinces, and does not show enough consistency to be considered as an independent biogeographic province as proposed by Palacio (1980). Observing the distribution of species along the southwestern Atlantic we find an increase in the proportion of species with greatest latitudinal ranges (occurring from...
