Comunidades de invertebrados en aguas subterráneas y su relación con variables ambientales
Provedor de dados: 67
Autores: Tione,María L; Bedano,José C; Blarasin,Mónica T.
En los últimos años los acuíferos comenzaron a ser estudiados desde una visión ecosistémica, considerando en particular a sus comunidades de invertebrados. En acuíferos loéssicos, de baja permeabilidad, hasta el momento no se han estudiado los invertebrados que los habitan. El objetivo de este trabajo fue evaluar la influencia de variables ambientales en las comunidades de invertebrados en el acuífero freático loéssico de la cuenca del arroyo La Colacha (Córdoba). Se seleccionaron siete perforaciones según el espesor de la zona no saturada y el uso de la tierra circundante, y un ambiente superficial, considerado como referencia. Se efectuaron dos muestreos durante un año hidrológico. Las aguas analizadas fueron caracterizadas como aguas dulces, a excepción...

Autores: Stuardo,José R; Vega,René.
The Cephalocarid, Sandersiella chilenica sp. nov. from Coliumo Bay, Central Chile ( 36º 32' S lat.; 72º56' W long) is described. The new species was collected at only one bottom station (station 4) in a grid of 11 stations sampled monthly during 1982-83, with predominating fractions of fine sand, silt and clay. Four other species of the genus are so far known (Sandersiella acuminata Shiino 1965, and S.kikuchii Shimomura &amp;amp; Akiyama, 2008, from Japan, S. calmani Hessler &amp;amp; Sanders 1973 from off Perú, and S. bathyalis Hessler &amp;amp; Sanders 1973, from Walvis Ridge, and off Namibia, SE Atlantic, and off Santos, Brazil). S. chilenica sp. nov, is differentiated from each of these by its comparatively greater maximal length, its shorter and...

In silico analysis of polymorphic microsatellites in penaeid shrimp and construction of a free-access database
Provedor de dados: 74
Autores: Freitas,Patrícia Domingues de; Pinheiro,Allysson Pontes; Silva,Thiago Buosi; Galetti Junior,Pedro Manoel.
We performed an in silico analysis of all microsatellites so far described for penaeid shrimp and for which the polymorphic behavior has previously been analyzed. The objective of the study was to evaluate the structural characteristics of these microsatellites and identifying patterns which allow the characterization of the nature of these sequences in the penaeid genome. All data were compiled in a free-access database specially constructed for this study. Three hundred non-mononucleotide polymorphic microsatellite loci described for 12 shrimp species belonging to the family Penaeidae were analyzed and simple and compound microsatellites with di-, tri-, tetra-, penta- and hexanucleotide motifs were found. Dinucleotides and trinucleotides were the most...

Genetic structure of the sea-bob shrimp (Xiphopenaeus kroyeri Heller, 1862; Decapoda, Penaeidae) along the Brazilian southeastern coast
Provedor de dados: 74
Autores: Voloch,Carolina Moreira; Solé-Cava,Antonio Mateo.
The sea-bob shrimp, Xiphopenaeus kroyeri, is one of the most important economic marine resources along the entire Brazilian coast. Nevertheless, despite its economic importance, no studies have examined the population genetics of this species. In this paper, we used ten allozyme loci to study the pattern of genetic structuring in X. kroyeri along the southeastern Brazilian coast. Seven of the ten analyzed loci were polymorphic, yielding observed heterozygosity values higher than those reported for other penaeid shrimps. The population from São Paulo was significantly different from the other two populations (Rio de Janeiro and Espírito Santo), which, in turn, seem to form a single panmitic unit. Therefore, our results clearly indicate that conservation...

Ciclo de vida pós-marsupial e crescimento de Metamysidopsis elongata atlantica (Crustacea, Mysidacea, Mysidae) em cultivo de laboratório
Provedor de dados: 76
Autores: Gama,Andréa Mara da Silva; Montú,Mônica Adelina; Gusmão,Luiz Felipe M. de.
Metamysidopsis elongata atlantica (Bacescu, 1968) was reared in the laboratory for 45 days at 20±1°C and salinity of 30ppt. Growth curves (von Bertalanffy model) were calculated for both sexes and for each sex. The daily rate of carapace growth was significantly different between females and males (F test, p &lt;0.05). Before the sexual maturity (14 days), the growth rate of females was higher than that of males (females, 0.0457 mm day-1; males, 0.0448 mm day-1). After the maturity (15 to 45 days), these rates decreased similarly for both sexes (females, 0.0203 mm day-1; males, 0.0174mm day-1). The average growth rate was 0.0207mm day-1 over the 45 days. Twelve molts were observed in a period of 60 days. The first five molts occurred up to 14 days old (age...

Evaluation of the stomach contents of Eriphia gonagra from a rocky shore in the southeastern Brazilian coast
Provedor de dados: 76
Autores: Rodrigues,Larissa R.; Góes,João M. de; Silva,Thiago E. da; Teixeira,Gustavo M.; Andrade,Luciana S. de; Fransozo,Adilson.
ABSTRACT The rocky shores of Praia Grande, in Ubatuba (São Paulo, Brazil), are formed by rock and Sabellaridae polychaete sandy reefs. These microenvironments offer shelters and foraging areas for several marine organisms and attracts many tourists. The crab Eriphia gonagra (Fabricius, 1781) inhabits these structures and can be used as a bioindicator, since they may be affected by anthropogenic actions. This study evaluated the stomach contents and characterized the feeding habits of an E. gonagra population, inhabiting the rocky shores from Praia Grande, taking into account the sex, size, and microhabitat. Monthly samplings were performed in 1996 and 1997 and the crabs were manually captured on the rocky surface or into of the sand reefs. So, the...

Provedor de dados: 76
Autores: Almerão,Maurício P.; Mendonça Jr.,Milton de S.; Quadros,Aline F.; Pedó,Ezequiel; Silva,Luiz G. R.; Araujo,Paula Beatriz.
We analysed species abundance and composition during one year of sampling at Itapuã State Park, a conservation unit in the State of Rio Grande do Sul, southern Brazil. Samples were collected monthly from May 2003 to April 2004 along a 4 km forest trail divided in three transects along the slopes of a small hill. Terrestrial isopods were hand searched by three people for 40 minutes at two sampling sites along each transect, summing 240 minutes of sampling effort per transect per month. Six species distributed in six families were found. The collector curve stabilised when half the samples were taken, demonstrating sampling sufficiency: analytical estimates did not predict more species to be found in the trail. Atlantoscia floridana (van Name, 1940) was...

Taxonomic revision of doubtful Brazilian freshwater shrimp species of genus Macrobrachium (Decapoda, Palaemonidae)
Provedor de dados: 76
Autores: Pileggi,Leonardo G.; Mantelatto,Fernando L.
The freshwater prawns of the genus Macrobrachium Spence Bate, 1868 are widely distributed in rivers of tropical and subtropical regions and represent an interesting group with controversial taxonomy. The morphological characters traditionally used to separate species have shown a high intraspecific variation. Doubts about the status of M. birai Lobão, Melo &amp;amp; Fernandes, 1986, M. holthuisi Genofre &amp;amp; Lobão, 1978 and M. petronioi Melo, Lobão &amp;amp; Fernandes, 1986 have been arisen due to the high resemblance of the former two species with M. olfersi (Wiegmann, 1836), and the latter one with M. potiuna (Müller, 1880). Therefore, we performed a detailed morphological analysis of these species, including new characters not usually used in the...

Shape and size variations of Aegla uruguayana (Anomura, Aeglidae) under laboratory conditions: A geometric morphometric approach to the growth
Provedor de dados: 76
Autores: Diawol,Valeria P.; Giri,Federico; Collins,Pablo A.
Crustacean growth studies typically use modal analysis rather than focusing on the growth of individuals. In the present work, we use geometric morphometrics to determine how organism shape and size varies during the life of the freshwater crab, Aegla uruguayana Schmitt, 1942. A total of 66 individuals from diverse life cycle stages were examined daily and each exuvia was recorded. Digital images of the dorsal region of the cephalothorax were obtained for each exuvia and were subsequently used to record landmark configurations. Moult increment and intermoult period were estimated for each crab. Differences in shape between crabs of different sizes (allometry) and sexes (sexual dimorphism; SD) were observed. Allometry was registered among specimens;...

Peripatric speciation drives diversification and distributional pattern of reef Hermit Crabs (Decapoda: Diogenidae: Calcinus)
Provedor de dados: 5
Autores: Malay, Maria Celia (machel) D.; Paulay, Gustav.
The diversity on coral reefs has long captivated observers. We examine the mechanisms of speciation, role of ecology in speciation, and patterns of species distribution in a typical reef-associated clade-the diverse and colorful Calcinus hermit crabs-to address the origin of tropical marine diversity. We sequenced COI, 16S, and H3 gene regions for similar to 90% of 56 putative species, including nine undescribed, "cryptic" taxa, and mapped their distributions. Speciation in Calcinus is largely peripatric at remote locations. Allopatric species pairs are younger than sympatric ones, and molecular clock analyses suggest that &gt; 2 million years are needed for secondary sympatry. Substantial niche conservatism is evident within clades, as well as a few major...

La production chez les crustacés. Rôle dans les écosystèmes et utilisations
Provedor de dados: 5
Autores: Khmeleva, N; Goloubev, A.
This monograph is the first to state by a systematic research the rules which control the production of the organic losses in shape of eggs and exoskeletons during the life of Crustacea. The weight and the energy content of the material thrown out are the chief criteria selected to characterize the germinal production, relative to the egg-mass, and the exuvial production, relative to the organic fraction of the exoskeleton. The determination of these parameters, at the level of the organism or of the population, takes into account the systematic position of the animals, the duration of their intermolt periods, fecundity and other indices in relation to environmental factors. The loss of matter and energy with reproduction and molting(studied for different...

Introduction : Since 1978, new measures to better manage lobster fisheries were implemented in the Celtic Sea within the context of Community regulations. Meshing, in particular, was set at 60mm, but many owners, in order to maintain sufficient leeway vis-à-vis the regulations and to avoid administrative hassles adopted at the outset fish meshing at 70mm, even 80mm. Certain habits aiming to compensate for the losses due to these increases were established: Adoption of better-performing trawls, increase in the secondary catch and enlargement of the fisheries. At the same time, especially because of strong demand from international bodies, OEM and especially EEC, knowledge about the lobster spread and more reliable assessments were achieved, the main problem...

Problemes de morphogenese cuticulaire chez les crustaces
Provedor de dados: 5
Autores: Bouligand, Y.
The crustacean integument is an excellent model for the study of cuticular morphogenesis, at different organization levels. At the supermolecular level, subunits of chitin and protein assemble and show the organization of a stabilized liquid crystal. At higher levels corresponding to cells and cells populations, several controls are involved in the fine architecture of the epicuticle, in the mineral distribution and in characters which concern the whole animal, such as isometric or allometric growth.

Xylocythere sarrazinae, a new cytherurid ostracod (Crustacea) from a hydrothermal vent field on the Juan de Fuca Ridge, northeast Pacific Ocean, and its phylogenetic position within Cytheroidea
Provedor de dados: 5
Autores: Tanaka, Hayato; Lelièvre, Yann; Yasuhara, Moriaki.
This paper described Xylocythere sarrazinae sp. nov. (Ostracoda: Cytheroidea: Cytheruridae: Eucytherurinae), collected at 2196 m depth from the Grotto hydrothermal edifice (Main Endeavor Field, Juan de Fuca Ridge) in the northeastern Pacific Ocean. This new species was found living in association with Ridgeia piscesae tubeworm assemblages. It is the second representative of Xylocythere described from such vents. Xylocythere sarrazinae sp. nov. is easily distinguished from the seven described species of Xylocythere by the surface ornamentations of its carapace, with the most similar species to it being Xylocythere pointillissima Maddocks &amp; Steineck, 1987. However, Xylocythere sarrazinae sp. nov can be distinguished from X. pointillissima based on the...

Fécondité de Nephrops norvegicus dans le golfe de Gascogne
Provedor de dados: 5
Autores: Morizur, Yvon; Conan, Gérard; Guenole, A.; Omnes, Marie-helene.
Females of the Norway lobster Nephrops norvegicus (L.) incubate their eggs under the abdomen for a period of several months. The authors estimated the individual fecundity of N. norvegicus (1) before spawning, and (2) at the end of the incubation period. From these two relationships, they then calculated the average egg loss. Egg loss seems to be relatively higher for small females than for large ones. The mean egg loss estimated for the Bay of Biscay (45%) differs from the only other existing value (75%) calculated by other authors for Portuguese waters. Egg loss may regulate stock-density, and may be a mechanism intervening in stock-recruitment.

Temperature resistance studies on the deep-sea vent shrimp Mirocaris fortunata
Provedor de dados: 5
Autores: Shillito, B; Le Bris, Nadine; Hourdez, S; Ravaux, J; Cottin, D; Caprais, Jean-claude; Jollivet, D; Gaill, F.
The shrimp Mirocaris fortunata is a hydrothermal vent species that is found at most vent-sites along the Mid-Atlantic Ridge. This endemic species is found across a hydrothermal gradient, with thermal conditions ranging from 2-9 degrees C in ambient seawater to fairly warm values of about 25 degrees C. We performed in vivo experiments on M. fortunata specimens originating from different sites and depths (850 m to 2300 m), both at atmospheric pressure and in pressurized aquaria, to characterise the upper thermal limits of this species. Atmospheric pressure results show that thermal physiology should be studied at each population's native pressure. At in situ pressure, shrimps from Menez Gwen (850 m depth) and Lucky Strike (1700 m depth) do not survive...

Autores: Laroche, Jean; Benoely,; Siaviri, A.
Traditional fishing using beach seines was studied over a period of one year at the mouth of the Onilahy river. The catches/efforts were recorded on a daily basis, biological sampling and the measurement of hydrological parameters being carried out twice a month. The moderate variations of salinity and temperature (14 &lt; salinity &lt; 35; 25 degrees C &lt; temperature &lt; 30 degrees C) which were observed in the estuary can be explained by the semiarid climate of the area. Four species of penaeid shrimps are to be found on the Onilahy: Metapenaeus monoceros, Panaeus indicus, Penaeus monodon and Penaeus japonicus, which were mainly caught at the subadult/adult stage with a Carapace length between 10 and 50 mm. The presence of these important sizes at the...

Controle neuromodulateur et flexibilite d'expression d'un reseau neuronal central: Le systeme pylorique des crustaces decapodes
Provedor de dados: 5
Autores: Nagy, F; Cazalets, J; Moulins, M.
In decapod Crustacea, the rhythmic activity of the pyloric filter is programmed within a network of 14 neurons in the stomatogastric nervous system. The pyloric network activity is underlied by both the endogenous regenerative properties of its neurons and the organization of their synaptic connections. Both factors are controlled by central modulatory neurons. Two of these neurons were identified, the APM neuron, which induces, and the PS neuron, which suppresses, the regenerative properties of pyloric neurons. APM can start and PS can stop the rhythmic pyloric activity, but both of them can also change its expression. Because of this control, the pyloric network can produce several types of motor pattern.

The tanaidacean crustacean, Zeuxo holdichi was first described from Arcachon Bay, France, by Bamber in 1990. Since then, this species has been recorded several times in Europe, from Iberian Peninsula to Germany. In this present study, we report new records of this species along the northern coasts of France bordering the English Channel. It is hypothesized that Z. holdichi is being spread because of aquaculture activities.

Problèmes de santé publique liés à la consommation de fruits de mer

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...

Utilisation de critères fonctionnels (présence de spermatophore, maturation des ovaires) pour la détermination de la taille et de l'âge à maturité sexuelle des Nephrops norvegicus femelles de la région sud-Bretagne
Provedor de dados: 5
Autores: Morizur, Yvon.
The average length at which female Nephrops norvegicus attain their first maturity was determined during 1977 and 1978 by following the presence of spermatophores and development of the ovaries. During 1978, females were sexually mature at the age of 2 but in 1977 they did not mature before the age of 3. The cumulative maturity curves are sigmoid, due to an overlapping of Gaussian curves. A logistic equation was developed to calculate the percentage of mature females at each length. There is no evidence that the present fishing levels reduce the chances of a female with developing ovaries to be fertilized, since 90 to 100% of such females bear spermatophores.

Provedor de dados: 5
Autores: Morizur, Yvon.
The size and age at sexual maturity of the lobsters was determined by secondary sexual characteristics (1) morphological criteria such as length of P1 protopodite, size of the abdomen, and the presence or absence of ovarian hairs in the female; and (2) functional criteria such as the presence of spermatophores in the female and development of the ovaries. A study of fecundity was carried out after maturation of the ovaries and at the end of incubation. The number of eggs lost during incubation was estimated at 45%. The contribution of different age classes to the global fecundity of the stock was simulated on a model of fecundity by recruits.

Antimicrobial peptides play a major role in innate immunity. The penaeidins, initially characterized from the shrimp Litopenaeus vannamei, are a family of antimicrobial peptides that appear to be expressed in all penaeid shrimps. As of recent, a large number of penaeid nucleotide sequences have been identified from a variety of penaeid shrimp species and these sequences currently reside in several databases under unique identifiers with no nomenclatural continuity. To facilitate research in this field and avoid potential confusion due to a diverse number of nomenclatural designations, we have made a systematic effort to collect, analyse, and classify all the penaeidin sequences available in every database. We have identified a common penaeidin signature...

Distribution of bacteria and associated minerals in the gill chamber of the vent shrimp Rimicaris exoculata and related biogeochemical processes
Provedor de dados: 5
Autores: Zbinden, M; Le Bris, Nadine; Gaill, F; Compere, P.
The shrimp Rimicaris exoculata dominates the megafauna of some Mid-Atlantic Ridge hydrothermal vent fields. This species harbours a rich bacterial epibiosis inside its gill chamber. At the 'Rainbow' vent site (36degrees 14.0'N), the epibionts are associated with iron oxide deposits. Investigation of both bacteria and minerals by scanning electron microscopy (SEM) and X-ray microanalysis (EDX) revealed 3 distinct compartments in the gill chamber: (1) the lower pre-branchial chamber, housing bacteria but devoid of minerals; (2) the 'true' branchial chamber, containing the gills and devoid of both bacteria and minerals; and (3) the upper pre-branchial chamber, housing the main ectosymbiotic bacterial community and associated mineral deposits.

Heat-shock response and temperature resistance in the deep-sea vent shrimp Rimicaris exoculata
Provedor de dados: 5
Autores: Ravaux, Juliette; Gaill, Françoise; Le Bris, Nadine; Sarradin, Pierre-marie; Jollivet, Didier; Shillito, Bruce.
The shrimp Rimicaris exoculata swarms around hydrothermal black smoker chimneys at most vent sites along the Mid-Atlantic Ridge. This species maintains close proximity to the hydrothermal fluid, where temperatures can reach 350degreesC and steep thermal and chemical gradients are expected. We performed in vivo experiments in pressurized aquaria to determine the upper thermal limit [critical thermal maximum (CTmax)] of R. exoculata and to investigate some characteristics of the shrimp stress response to heat exposure. These experiments showed that the shrimp does not tolerate sustained exposure to temperatures in the 33-37degreesC range (CTmax). A heat-inducible stress protein belonging to the hsp70 family was identified in R. exoculata, and its synthesis...

Feeding trials were conducted with over 22 different crustacean species to compare the potential use of two diets as Standard Reference Diets (SRD) in crustacean research. The two diets (BML 81 S, a casein/albumin based formula developed at the University of California, Bodega Marine Laboratory, and HFX CRD 84, a crab protein concentrate based diet formulated at the Canadian Department of Fisheries and Oceans Halifax Laboratory) were about equal in performance for most species tested. Though neither diet was an ideal SRD, the HFX CRD 84 formulation based upon a purified protein of marine origin was accepted as the interim SRD for use in aquatic crustacean studies.

Effective methods of traceability are urgently required for use in research as weil as in different types of aquaculture operations and to control trade in aquatic animais and praducts. In regard to the marking of fish, many different tagging methods have been described and the method to be used depends on the purpose and need for tagging. In contrast, for molluscs and crustaceans, only a few methods of marking such animais have been described, due to the practical difficulties.

Description of a new species of Petrolisthes in the Indo-West Pacific with a redefinition of P. hastatus Stimpson, 1858 and resurrection of P. inermis (Heller, 1862) (Crustacea, Anomura, Porcellanidae)
Provedor de dados: 5
Autores: Werding, Bernd; Hiller, Alexandra.
The porcellanid crab Petrolisthes hastatus Stimpson, 1858, has been traditionally viewed as a highly variable species with a wide distribution in the West Pacific. For more than a century there has been taxonomic confusion of this species with morphologically similar taxa, some of which were synonymized with Stimpson's taxon. We redefine P. hastatus, resurrect P. inermis as a valid species, discuss the status of P. tenkatei De Man, 1893, and describe a new species as P. elegantissimus from Indonesia.

Autores: Tong, P. H. S; Auda, Y; Populus, Jacques; Aizpuru, M; Al Habshi, A. Al; Blasco, F.
This study is an attempt to produce an assessment of the impact of shrimp aquaculture in the Mekong Delta (Viet Nam) on mangrove ecosystems. For this exercise we selected two sub-areas (Ca Mau and Tra Vinh provinces) encompassing a variety of land uses and ecological conditions. Twenty stations in Tra Vinh and 15 stations in Ca Mau have been surveyed several times from September 2000 to March 2002. Field investigations included mangrove soils studies, measurements of pH and salinity of the water, analysis of mangrove flora, and density and structure of the vegetation. Four Systeme Probatoire de l'Observation de la Terre (SPOT) scenes were used for the discrimination of mangrove types and for the delineation of landscape units. For the first time, five...

Macrostylis metallicola     spec. nov.—an isopod with geographically clustered genetic variability from a polymetallic-nodule area in the Clarion-Clipperton Fracture Zone
Provedor de dados: 5
Autores: Riehl, Torben; De Smet, Bart.
Background: The Clarion-Clipperton Fracture Zone (CCFZ) in the Northeast Central Pacific Ocean is a region of heightened scientific and public interest because of its wealth in manganese nodules. Due to a poor ecological understanding at the abyssal seafloor and limited knowledge of the organisms inhabiting this area, huge efforts in alpha taxonomy are required. To predict and manage potential hazards associated with future mining, taxonomy is an essential first step to grasp fundamental ecosystem traits, such as biogeographic patterns, connectivity, and the potential for post-impact recolonization. Amongst samples from the Global Sea Mineral Resources NV exploration area (EA) in the CCFZ an undescribed species of the isopod crustacean family Macrostylidae...

Cylisticus convexus, a rare synanthropic woodlouse in The Netherlands (Crustacea: Isopoda: Cylisticidae)  Until recently, the occurrence of Cylisticus convexus (De Geer, 1778) in the Netherlands was uncertain. The only certain old record dates from March 1927, when the species was collected at the coal-shed of the Zoological Museum at Amsterdam. During the last years, two specimens have been collected on semi-natural sites. Both were found on a dike, one near Everdingen, in the province of Gelderland, and one near Ritthem, in the province of Zeeland. These are the first records of C. convexus in the field. Yet the species certainly is very rare in The Netherlands. The most important morphological characteristics of the species are described and...

Sphaeromatidae (Crustacea, Isopoda) of the Beagle Channel and description of Cymodopsis beageli n. sp
Provedor de dados: 16
Autores: Brandt, Angelina.
During an expedition with RV Victor Hensen (1994) and the RV Polarstern (1996) Isopoda Sphaeromatidae were collected in and off the eastern entrance of the Beagle Channel. The species found, Caecocassidias patagonica Kussakin, 1967, Cassidinopsis emarginata (Guérin-Méneville, 1843) and Moruloidea darwinii (Cunningham, 1871), were previously all poorly or insufficiently described; therefore a redescription is presented herein. Exosphaeroma gigas (Leach, 1818) was also collected frequently, but it was already redescribed earlier and thus only the localities are presented. Moreover, a new species, Cymodopsis beageli, n.sp., which is most closely allied to Cymodopsis sphyracephalata Hurley &amp; Janssen, 1977, is described from the Beagle Channel.

Redescription of two species of Cymbasoma from southwest Britain and from Indonesia (Copepoda: Monstrileoida), with notes on taxonomy
Provedor de dados: 16
Autores: Suárez-Morales, E.
One of the main current problems in the taxonomy of the monstrilloid copepods is the lack of detailed descriptions. Most of these descriptions are poorly illustrated making the recognition of species even more difficult. Reexamination of specimens deposited in different museums of the world has vielded new taxa but also the opportunity of redescribing these species according to upgraded standards. Two species of Cymbasoma, one from southwest England and the other from the Java Sea are redescribed from the holotype specimens following upgraded standards. Both species are compared with related forms for the first time. The former species (C. striatus) has several interesting characters of which the most important is a fringe of striations covering about half...

Laophonte trispinosa Sewell is reported here from various localities in the Indian and the West Pacific Ocean, and is allocated to the herein erected genus Xanthilaophonte gen. nov. A second species, X. carcinicola spec. nov. is described from Indon »sia. The genus Xanthilaophonte gen. nov. is most closely related with Echinolaophonte Nicholls. Both species of this genus live in association with decapods, mainly Xanthidae, and occur on the carapax of their hosts, between the bristles. Comparison of the copepodid development clearly shows that the advanced morphology of Xanthilaophonte gen. nov. resulted from heterochrony events.

Possible lattice organs in Cretaceous Thylacocephala
Provedor de dados: 16
Autores: Lange, Sven; Schram, Frederick R.
Structures, reminiscent of the lattice organs in thecostracan crustaceans, are described from the carapace cuticle of Cretaceous thylacocephalans. The new lattice organ like structures occur in pairs along the dorsal midline. While these have a similar outline to true lattice organs, they seem to lack pores and do not occur in the highly apomorphic pattern found in thecostracans. These discrepancies do not easily support earlier ideas of a position of the thylacocephalans within the thecostracans. The significance of the possible lattice organs for inferring a relationship between thylacocephalans and thecostracans is discussed.

Platypodiella georgei spec. nov. (Brachyura: Xanthidae), a new crab from the island of St. Helena, South Atlantic Ocean, with notes on the genus Platypodiella Guinot, 1967
Provedor de dados: 16
Autores: Hartog, J.C. den; Türkay, M.
A new species of Platypodiella Guinot, 1967, from the island of St. Helena, P. georgei spec, nov., is described. This species was found associated with encrusting species of Palythoa Lamouroux, 1816 (Zoantharia). Ample evidence is presented that both the eastern Atlantic P. picta (A. Milne-Edwards, 1869) and the western Atlantic P. spectabilis (Herbst, 1794) also live habitually associated with encrusting species of Palythoa, rarely with other zoantharians. For each of the two East-Pacific members of the genus, P. rotundata (Stimpson, 1860) and P. gemmata (Rathbun, 1902), there is at least one rather detailed published record suggesting that these species too associate with Palythoa. Thus, this habit would seem to go for all five members of the genus. Data...

Autores: Damiano, Giuseppina; Garassino, Alessandro; Scali, Stefano; Teruzzi, Giorgio.
The study of fossil decapods have shown the need for reliable statistics to document the value of the characters considered. Morphometric data, however, are usually absent in scientific papers on living decapod crustaceans since neontological systematists normally analyze internal organs and tissues not available in fossils. A series of morphometric data for two extant species have been processed statistically in order to obtain numerical models that could be applied to fossil species showing morphological affinities.

Utility of 18S rDNA and ITS sequences as population markers for Lepeophtheirus salmonis (Copepoda: Caligidae) parasitising Atlantic salmon (Salmo salar) in Scotland
Provedor de dados: 16
Autores: Shinn, A.P.; Banks, B.A.; Tange, N.; Bron, J.E.; Sommerville, C.; Aoki, T.; Wootten, R.
Genetic differentiation within the salmon louse Lepeophtheirus salmonis (Krøyer, 1837), was investigated by the sequencing of specific nucleotide regions. Partial sequences of the 18S ribosomal RNA gene and the ribosomal internal transcribed spacer (ITS-1) region from single sea lice were amplified by the polymerase chain reaction (PCR). Lice were collected from wild and farmed Atlantic salmon ( Salmo salar L., 1758) from nine selected localities around the Scottish coastline. A 0.9kb fragment of the 18S ribosomal RNA gene was amplified and compared for several samples of lice which showed no observable differences between the lice from different collection sites confirming the absence of cryptic species. The 454 nucleotide ITS-1 sequence showed...

Provedor de dados: 16
Autores: Ledoyer, M.
This study deals with Caridean fauna living between the leaves of New-Caledonian seagrassmeadows (Cymodocea sp. principally) from zero to about eight meters and sampled during day and night. Twenty species (all figured) were caught (excluding Alpheidae). All are known. Nevertheless, in some cases, small variations have been observed by comparison with the same species from other areas. Presently, 70 species are recognized from New-Caledonian marine waters, including the 17 species reported in this papier for the first time from that region. Comparison with Caridean fauna of seagrass-meadows of other areas (Australia, Japan, Madagascar) shows a very important resemblance between them.

Autores: Suárez-Morales, E.
A specimen of a monstrilloid copepod collected by the U.S. Fisheries Steamer “Albatross“ in the Sulu Sea, west coast of Mindanao, Philippines, and deposited in the U.S. National Museum of Natural History, was taxonomically restudied. The specimen had been originally identified as a male of Monstrilla serricornis Sars by C.B. Wilson. Reexamination revealed that the specimen represents a new species of the genus Cymbasoma, C. mcalicei. This species can be distinguished by its body proportions and body size, but mainly by the structure of the genital lappets, which have a serrated posterior margin unique in the genus. This is the seventh species of Cymbasoma reported from East or Southeast Asia.

New studies of decapod crustaceans from the Upper Jurassic lithographic limestones of southern Germany
Provedor de dados: 16
Autores: Schweigert, Günter; Garassino, Alessandro.
The Upper Jurassic lithographic limestones of southern Germany have long been known for their exceptional preservation of decapod crustaceans (Glaessner, 1965), similar to the Upper Cretaceous of Lebanon (Hakel, Hadjoula) and the still poorly known Callovian strata at La Voulte-sur-Rhône (France). In these non-bioturbated limestones, the decay of decapod skeletons is reduced, so that besides the heavily mineralized chelae and carapace often even delicate structures such as pleopods and antennae are preserved. Recently, new decapod material has been obtained from both scientific and commercial excavations, in part in reopened lithographic limestone quarries.

Autores: Boulanouar, M.; Yacoubi, M.; Messouli, M.; Coineau, N.
The interstitial crustacean isopods of the genus Microcharon (Microparasellidae) are relatively well-diversified and widely distributed in Morocco. A new species, M. boutini, is described. The 5-dentate mandibular pars incisiva, the elongated inner lobe of the exopodite, and the reduced armature of the first male pleopod characterize the species. M. boutini n. sp. belongs to the monophyletic messoulii group of species, the most primitive representatives of the genus. The distribution of M. boutini n. sp. covers both the northwestern part of the Jbilet and the nearest adjacent plain, as well as the High Atlas of the Marrakech piedmont. From a historical biogeographic point of view, interstitial ancestral marine populations would have been left in...

Aspects of the evolution and biogeography of stygobiontic Isopoda (Crustacea: Peracarida)
Provedor de dados: 16
Autores: Wägele, Johann-Wolfgang.
The evolution of the stygobiontic isopods is discussed correlating the phylogenetic system with biogeography. All stygobiontic isopods probably are derived from remote marine ancestors. The colonization of subterranean aquatic biotopes occurred in two ways: (1) via the coastal groundwater in the case of the Microparasellidae, Gnathostenetroididae, Stenetriidae, and in Cyathura (Stygocyathura), (2) in most families, however, via epigean freshwater ancestors. Ancient freshwater isopods that must already have existed before the Cretaceous and whose stygobiontic phylogenetic lines partly must have existed before the opening of the Atlantic are the Aselloidea, Calabozoida, Phreatoicidea, and probably also the Protojaniridae. In the course of Cretaceous and...

Neocyclops medius Herbst, 1955 and Neocyclops vicinus (Herbst, 1955) are redescribed from intertidal interstitial water of sandy beaches along the Brazilian coast. The male of N. vicinus is described for the first time. Neocyclops vicinus can be easily distinguished from N. medius by the relatively longer caudal rami, the presence of a mandibular palp, and the sexually dimorphic antenna. This study revealed the leg 4 endopodite segments 2 and 3 as being fused in both species. The terminal segment of the 2-segmented leg 4 endopodite of the copepodite 5 does not differentiate into 2 distinct segments during the molt to adult. The plane of fusion is marked by a thin and incomplete line on the frontal surface. This scar was erroneously interpreted as a...

Early Cretaceous decapod Crustacea from the Neuquén Basin, west-central Argentina
Provedor de dados: 16
Autores: Aguirre-Urreta, Maria Beatriz.
Marine deposits of the Neuquén Basin of west-central Argentina (southern South America) are richly fossiliferous; its Mesozoic invertebrate faunas, represented mostly by molluscs, have been extensively studied since the nineteenth century. However, Early Cretaceous decapod crustaceans are far less known, although part of the systematic framework has been published (Aguirre-Urreta, 1989). The aim of the present note is to provide updated information based on ongoing research into the systematics and taphonomy of this crustacean group in the Neuquén Basin.

A new species of Pseudoniphargus (Crustacea, Amphipoda) from subterranean water of northeastern Morocco: Historical biogeography and evolutionary aspects
Provedor de dados: 16
Autores: Abiari, A. Fakher el; Oulbaz, Z.; Messouli, M.; Coineau, N.
A new species of Pseudoniphargus, P. longiflagellum (Crustacea, Amphipoda) is described from subterranean fresh water of the Riftan region of Morocco. This species is closely related to the group P. ruffoi-P. longipes, which shares several apomorphic characters. The two-step model of colonization and evolution provides an understanding of the origin and the age of this stygobiont. P. longiflagellum is derived from marine ancestors that lived in the coastal groundwater of the Tethyan South-Rifian channel during the Miocene Tortonian period. The regression of this corridor during the late Tortonian period or at the beginning of the Messinian period may have played a major role in the evolutionary history through vicariance.

Developmental origins of normal and anomalous random right-left asymmetry: lateral inhibition versus developmental error in a threshold trait
Provedor de dados: 16
Autores: Palmer, A.R.
Dramatic examples of right-left asymmetry often inspire adaptive explanations, simply because it is hard to imagine how such forms could not be functionally significant. But are conspicuous morphological asymmetries necessarily adaptive? Surprisingly, in some species where direction of asymmetry is random, asymmetry in bilaterally paired traits may arise as a developmental error in a threshold trait. When cases of asymmetry are rare within a species, they are easily recognized as developmental errors. However, as asymmetrical individuals become more common, or if the asymmetry is in a signaling trait, the temptation to advance an adaptive explanation grows, particularly if the asymmetry is not clearly maladaptive. Several models of the ontogeny of...

A revision of the genus Matuta Weber, 1795 (Crustacea: Brachyura: Calappidae)
Provedor de dados: 16
Autores: Galil, B.S.; Clark, P.F.
Introduction Amid the gaudily-coloured parade of tropical crabs few are more splendidly patterned than the matutine genera. But the patterns decorating these species brought about taxonomic disarray and from the very beginning they baffled their researchers. Already in 1817 Leach remarked: "the characters which distinguish the species are very obscure". MacLeay (1838) wrote in exasperation: "there are many species confounded together under the name Matuta victor, I do not consider the above names of the family and genus to possess any authority". Stebbing (1905) concurred: "From the interminable discussion of minute differences, as to the importance of which distinguished authors neither agree one with another nor always with themselves, it seems safe to...

Garthambrus, a new genus of deep water parthenopid crabs (Crustacea: Decapoda: Brachyura) from the Indo-Pacific, with description of a new species from the Seychelles
Provedor de dados: 16
Autores: Ng, P.K.L.
A new genus of parthenopid crab, Garthambrus gen. nov., characterised by a broad carapace with strongly raised branchial and gastric regions, distinctive rostrum, sub-cylindrical ambulatory meri and a long distal segment of the second male pleopod, is established for six deep water species from various parts of the Pacific. A new species, Garthambrus posidon spec, nov., is also described from depths of between 480 to 600 m off the Seychelles in the Indian Ocean. It differs from its closest congener, G. poupini (Garth, 1993), in having a proportionately broader carapace, less granulated carapace and chelipedal surfaces, and in the form of the carapace regions.

Elemental analysis of Scottish populations of the ectoparasitic copepod Lepeophtheirus salmonis
Provedor de dados: 16
Autores: Shinn, A.P.; Bron, J.E.; Gray, D.J.; Sommerville, C.
Conventional nebulisation ICPMS (Inductively Coupled Plasma Mass Spectrometry), was used to determine the concentration of a broad range of elements in the salmon louse Lepeophtheirus salmonis. Lice samples were collected from Atlantic salmon in seven localities (4 fish farms and 3 wild salmon fisheries) on two separate sampling occasions and prepared for analysis. Sixty six elements were measured, 35 of these were found to be variable and were subjected to univariate and multivariate statistical analysis. The results of the single element comparisons showed that not all individual sites could be discriminated from each other. Sea lice collected from cultured salmonids could be discriminated from those on wild salmonids at the same site using the elements...

A case of homonymy in fossil verrucid barnacles: Verruca withersi (Crustacea, Thoracica)
Provedor de dados: 16
Autores: Jagt, J.W.M.; Buckeridge, J.S.
For fossil verrucid barnacles, the name Verruca withersi appears to have been used twice; Schram &amp; Newman described material from the Albian-Cenomanian (Cretaceous) of Colombia, while Kruizinga had previously recorded a new species from the Pleistocene(?) or perhaps younger strata of Sumba (Indonesia). We do not consider V. withersi Schram &amp; Newman to be a cirripede, therefore no replacement name is needed for this junior synonym. Verruca withersi Kruizinga is a valid species related to the extant V. cookei.

Palaemon vicinus spec. nov. (Crustacea: Decapoda: Palaemonidae), a new species of caridean shrimp from the tropical eastern Atlantic
Provedor de dados: 16
Autores: Ashelby, C.W.
A new species of Palaemon, P. vicinus spec. nov., is described from the tropical eastern Atlantic. The new species is very close to P. elegans Rathke, 1837, under which name it was previously recorded from West Africa. Palaemon vicinus spec. nov. is easily separated from P. elegans by possessing a small tooth on the fifth abdominal pleuron (quadrate in P. elegans) and by having 2-3 rows of setae in the grooming brush of the fifth pereiopod (4-5 in P. elegans). The discovery of the new species amongst material identified as P. elegans further highlights the need to reassess species level characters in the genus Palaemon.

Autores: Pretus, J.L.
Odontozona addaia, a new species of stenopodid shrimp is described from a marine cave in the island of Minorca (Balearic Islands), being the first record of the genus for the western Mediterranean. One male and one ovigerous female were found during a systematic propspection of several Balearic caves during 1988. Sexual dimorphism is observed and described; the differences mainly concern a more developed third pereiopod in the male, and a distinct shape and armature of the pleonites and pleopods in both sexes. The distinction of this new taxon from the other known closely related species, O. minoica, is discussed.

The interstitial stygobites of the genus Microcharon (Crustacea, Isopoda, Microparasellidae) are highly diversified in Morocco, especially in the High Atlas. A new species from the North Saharan platform is described. Microcharon oubrahimae n. sp. is characterized by the original morphology of the first male pleopod which exhibits a concave inner margin of the distal part and a subdistal position of the armature. From a phylogenetic point of view, M. oubrahimae does not belong to the lineage which includes the Moroccan Atlasian species. In contrast, it belongs to the eastern- Mediterranean group of species. It is related to the species of the group M. orghidani-M. bureschi-M. phlegetonis from Romania and Bulgaria. The two-step model of colonization and...

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...

Provedor de dados: 16

Neocyclops (Protoneocyclops) ferrarii sp. n. is described from Candy’s Pond, Twin Cays, Belize. It is morphologically closest to N. (P.) wellsi Petkovski, 1986 from Mozambique and N. (P.) herbsti Petkovski, 1986 from the Red Sea. Pediger 1 in Neocyclops is distinct although reduced and often concealed beneath the cephalic shield. Specimens of Neocyclops (N.) vicinus and N. (N.) medius showed the same condition, warranting the supposition that the free pediger 1 is a consistent feature of the genus. The genital double somite bears a transverse cuticular thickening which apparently supports the seminal receptacle. The importance of the integumental pore patterns of the urosome and legs as useful taxonomic characters is pointed out.

In addition to a taxonomic review of the whole order Thermosbaenacea, the general morphology and chaetotaxy are discussed in detail. Due to the results of cuticular staining, and through the study of specimens with SEM techniques also, corrections to earlier interpretations could be made. A chaetotaxic classification, modified after the one of Watling (1989), is presented. In the taxonomic part 34 species are recognized, belonging to seven genera (one new), four families (one new). The examination of adult material of the type species of Monodella, i.e., Monodella stygicola Ruffo, 1949, warranted the creation of Tethysbaena gen. nov., to comprise all other taxa previously included in Monodella.

A note on the systematic position of the Bathynellacea (Crustacea, Malacostraca) using molecular evidence
Provedor de dados: 16
Autores: Camacho, Ana Isabel; Rey, Isabel; Dorda, Beatriz A.; Machordom, Annie; Valdecasas, Antonio G.
Molecular data for the mt 16S rDNA gene fragment of a bathynellacean is here presented for the first time and used to analyze the relationship of the group within the crustacean class Malacostraca (Arthropoda, Bathynellacea). Two contrasting views have classified the bathynelids as being cither within the order Syncarida or in a separate super-order Podophallocarida belonging to the infra-class Eonomostraca, a disagreement based mainly on debates over external and internal morphology. The preliminary analyses offered here in question the placement of this Bathynellacea within the Syncarida, and suggest the need for a further study of relationships among the malacostracan groups.

Nieuwe vindplaatsen van het in Nederland uitgestorven gewaande vlokreeftje Echinogammarus stoerensis (Crustacea: Amphipoda: Gammaridea)
Provedor de dados: 16
Autores: Faasse, M.A.
The amphipod Echinogammarus stoerensis not extinct in The Netherlands (Crustacea: Amphipoda: Gammaridea)  The gammaridean amphipod Echinogammarus stoerensis has never been a common species in the Netherlands, due to the scarcity of suitable habitats. It is typically found under boulders on a gravelly substrate, where a freshwater flow occurs over the littoral zone. As a result of reinforcement of sea dykes, the typical habitat disappeared from The Netherlands. However, E. stoerensis proves to survive in less suited substrates with more silt, and freshwater supply only from rain.

Autores: Lotufo, Guilherme Ribeiro; Falavigna da Rocha, Carlos Eduardo.
Cuipora janaina gen. n., sp. n., and Cyclopina caiala sp. n. are described from the interstitial water of a sandy beach in Salvador, Bahia (Brazil). Cuipora is distinguished from all other genera of the subfamily Cyclopininae in having the endopodite of legs 1-4 2-segmented and the terminal segment armed with 4 setae. Cuipora is compared to Erythropolites Huys &amp; Boxshall, 1990, Herbstina Huys &amp; Boxshall, 1990, and Cyclopina Claus, 1862, with which it has most morphological similarities. Cyclopina caiala sp. n. is distinguished by the structure of the leg 5 of the male and female and by a particular combination of characters of the mouthparts. Taxonomical problems involving Cylopina mediterranea Steuer, 1940 are discussed.

Decapod crustaceans from the Oligocene of the Ligure Piemontese Basin, northern Italy
Provedor de dados: 16
Autores: Angeli, Antonio De; Marangon, Sergio.
Lithologically, the decapod-bearing levels of Rupelian (Oligocene) age in the Ligure Piemontese Basin, are characterized by an alternation of greyish blue marls with nodular elements and silt-rich, occasionally sandy, marls. The fossil studied for the present note have been collected mainly from pebbles or nodules which were eroded out of the higher levels exposed of this sedimentary complex, referred to as the ‘Formazione di Molare’. These levels overli the ‘Formazioni continentali delle Brecce di Costa Cravara e Pianfolco’, studied by Charrier et al. (1964) and dated as Early Rupelian. The levels yielding brachyuran fossils were attributed by Allasinaz (1987) to the transition between the ‘Formazione di Molare’ and the overlying ‘Marne di Rigoroso’, and...

Carefully collected molecular data and rigorous analyses are revolutionizing today’s phylogenetic studies. Although molecular data have been used to estimate various invertebrate phylogenies lor more than a decade, this study is the first survey of different regions of mitochondrial DNA in isopod crustaceans assessing sequence divergence and hence the usefulness of these regions to infer phylogeny at different hierarchical levels. 1 evaluate three loci from the mitochondrial genome (two ribosomal RNAs (12S, 16S) and one protein-coding (COI)) for their appropriateness in inferring isopod phylogeny at the suborder level and below. The patterns are similar for all three loci with the most speciose suborders of isopods also having the most divergent...

Three new sympatric species of remipede crustaceans, Speleonectes tanumekes, Speleonectes parabenjamini and Speleonectes minnsi, are described from an anchihaline cave on Great Exuma Island in the central Bahamas. Speleonectes tanumekes is a comparatively long and slender species distinguished by the largest number of trunk segments found in remipedes to date. Speleonectes parabenjamini is morphologically closely related to Speleonectes benjamini, but differs from the latter species by several distinct autapomorphies. Speleonectes minnsi is characterized by comparatively robust maxillules. The occurrence of three sympatric species is a remarkable record for the Remipedia adding to a total of 10 sympatric taxa. We discuss the high diversity of remipedes in...

Many papers on the taxonomy of fossil crustaceans are often based upon poorly preserved material and/or specimens that have been insufficiently prepared. The purpose of the present note is to outline some preparation methods that are applied in our (J.S.H. Collins and S.L.J.) ongoing studies of anomuran and brachyuran decapods from the Middle Danian limestones at Fakse quarry (Denmark), which have greatly enhanced the quality of our material. The techniques briefly outlined here involve: 1 – staining method; 2 – water blasting (as a cleaning tool in preparation of fossils); and 3 – negative preparation (with acid). Some of these techniques will have wide applications in other fields of paleontological research.

Un nouveau Microparasellidae (Crustacé Isopode) du Haut-Atlas; aspects phylogénétiques et biogéographiques
Provedor de dados: 16
Autores: Yacoubi-Khebiza, M.; Boulanouar, M.; Coineau, N.
The interstitial stygobiotic isopods of the genus Microcharon (Crustacea) are diversified in Morocco. A new species, M. ourikensis, is described. The new species shows some original characters for this genus: large size, strong elongation in the first male pleopod exopodal inner lobe, 5-dentate mandibular pars incisiva, and 5 spines on the last mandibular palp segment. The species is a member of the Ibero-Maghrebin messoulii group. It is an endemic representative of the Ourika valley groundwater in the Moroccan High Atlas. It derives from a littoral marine ancestor which could have colonized the continental subterranean water during Turonian or Senonian Tethyan regressions.

Interpreting ecology and physiology of fossil decapod crustaceans
Provedor de dados: 16
Autores: Feldmann, Rodney M.
Decapods are the most diverse and complex group of crustaceans, adapted for life in all parts of the marine environment, many aquatic habitats, and some terrestrial niches. With this diversity of life styles, a vast range of morphotypes of decapods has evolved, exploiting almost every imaginable variation in morphology of the complex exoskeleton that characterizes them. Many of the morphological variants are a response to exploiting a particular niche in which the organisms live or an adaptation to particular behavioral characteristics. Assessing the significance of morphological variation in the fossil record is challenging because of the taphonomic overprint that results in loss of soft tissue, preservation of partial remains of hard parts, and vastly...

Provedor de dados: 16
Autores: Henry, D.P.; Mclaughlin, P.A.
Since Darwin's (1854) description of 11 varieties of Megabalanus tintinnabulum (Linnaeus) [as Balanus tintinnabulum], 26 Recent taxa have been assigned to the genus. In this review, two taxa confounded by Darwin are reestablished [i.e., M. crispatus (Schroter) and M. dorbignii (Chenu)]. M. antillensis (Pilsbry) and M. intermedius (Darwin) are placed in synonymy with M. tintinnabulum sensu stricto. M. galapaganus (Pilsbry) is synonymized with M. peninsularis (Pilsbry) and M. xishaensis Xianqui &amp; Liu is considered a synonym of M. occator. Diagnoses and an illustrated key to the species are presented. Lectotypes are designated for M. tintinnabulum, M. crispatus, M. dorbignii, M. coccopoma (Darwin), M. spinosus (Chenu), M. validus (Darwin), and M. ajax...

A new spelaeogriphacean (Crustacea: Peracarida) from the Upper Jurassic of China
Provedor de dados: 16
Autores: Yan-bin, Shen; Taylor, Rod S.; Schram, Frederick R.
A new monotypic genus of Spelaeogriphacea is described from the Upper Jurassic of Liaoning Province, north-east China. This new genus and species brings the number of known spelaeogriphacean taxa to four, the others being two recent forms from Brazil and South Africa, and one from the Carboniferous of eastern Canada. The new Chinese form is morphologically (and phylogenetically) very similar to the recent spelaeogriphaceans, suggesting that the body plan seen in the recent Spelaeogriphacea was achieved relatively early in the history of the group. A cladistic analysis of this and several other peracaridan orders indicates that the Spelaeogriphacea may be a paraphyletic group. This suggests that much work remains to be done with respect to the taxonomy and...

The influence of recent inundations on the distribution pattern of the isopod Eluma purpurascens in the province of Zeeland (Crustacea: Isopoda: Oniscoidea)  Small scale mapping of Eluma purpurascens Budde-Lund, 1885 in the province of Zeeland revealed a remarkable distribution pattern. The species proved to be absent in parts which have been inundated during and after the second world war. This study shows that for the interpretation of distribution patterns the history of the study area should be considered.

Several species of “philosciid” Oniscidea are known from Brazil, most of them were found in the southern and eastern parts of this country. The genera Atlantoscia Ferrara &amp; Taiti, 1981, Benthana Budde-Lund, 1908 and Balloniscus Budde-Lund, 1908, the latter considered to represent a separate family Balloniscidae Vandel, 1963, are considered the only neotropical philosciids bearing respiratory areas on their pleopods. Therefore, representatives of these genera are re-examined to shed new light on the question whether these species can be considered to be a monophylum with the autapomorphy “respiratory areas present”, The phytogeny of the above-mentioned genera is discussed under morphological and biogeographical aspects. Furthermore, a remarkable new...

Autores: Hurley, D.E.
Besides his widespread activities in zoology and university development, Charles Chilton (1860—1929) was a pioneer in phreatic research who opened up the possibilities of the new science in the Southern Hemisphere. He described phreatic and subterranean species of Isopoda and Amphipoda from New Zealand, Australia and elsewhere and discussed the significance of their morphology and habitat. His finds included the first species of the widespread endemic Southern Hemisphere group, the Phreatoicoidea, and he pointed to Gondwanaland connections in this and other groups which he accepted and interpreted in the context of his time.

Autores: Ogwai, C.
The occurrence of ichthyoparasites and their cumulative effects was     observed at the inner Nyanza Gulf region of Lake Victoria. Protozoa,     Nematoda, Cestoda, Crustacea and Trematoda are mentioned. The parasite     fauna and the biocoenology of the hosts were studied and the seasonal     variation in infectivity was observed. Infection in the dams was     prevalent and was 75% at the peak. Some gill infected specimens were     examined between July and February. Infestation rates were higher     during the dry season. Males and juveniles dominated the infected     samples throughout the study period. The distribution pattern of the     hosts was also noted.

Abstract Eumunida pictaSmith, 1883, was considered for over a century an amphi-Atlantic species and the only representative of the genus in the Atlantic Ocean, until being split into three species: E. picta sensu stricto (from the northwestern Atlantic), E. bellade Saint Laurent &amp; Macpherson, 1990 and E. squamiferade Saint Laurent &amp; Macpherson, 1990 (from the northeastern and southeastern Atlantic, respectively). Eumunida is now expanded to include a new species, E. notialis, from off the Brazilian coast. Hence, this is the first record of Eumunida and Eumunididae from the southwestern Atlantic. The new species differs from all its Atlantic counterparts in having (1) four hepatic spines; (2) two carapace inframarginal spines; (3) the distal end of...

Epibiont occurrence on gastropod shells used by the hermit crab Loxopagurus loxochelis (Anomura: Diogenidae) on the northern coast of São Paulo, Brazil
Provedor de dados: 103
Autores: Ayres-Peres,Luciane; Mantelatto,Fernando L.
Gastropod shells occupied by hermit crabs are an important attachment substrate for epifauna, and these shells are often damaged. The present study aimed to characterize the epibionts and extent of damage for gastropod shells occupied by the hermit crab Loxopagurus loxochelis (Moreira, 1901). Samples were collected monthly over a period of one year (from July 2002 through June 2003), in the Caraguatatuba and Ubatuba regions, on the northern coast of São Paulo, Brazil. The sampling was performed using a fishing boat equipped with double-rig nets. The shells were identified and weighed. Loxopagurus loxochelis occupied 14 gastropod shell species in Caraguatatuba and five in Ubatuba. In the two areas, approximately 55% of these gastropod shells bore epibionts,...

Delayed metamorphosis in decapod crustaceans: evidence and consequences
Provedor de dados: 97
Autores: GEBAUER,PAULINA; PASCHKE,KURT; ANGER,KLAUS.
Most marine invertebrate species exhibit a complex life cycle including a planktonic larval phase and a benthic juvenile-adult phase. Metamorphosis and settlement are the links between these phases of development. In many species, metamorphosis is triggered by specific chemical and/or physical cues, mainly associated with the adult habitat. In the absence of such cues, competent larvae can delay their metamorphosis by a few days to several months. Most investigations on the delay of metamorphosis have been realised on sessile or sedentary species. In relation to mobile decapod crustaceans, the number of such studies is low, probably because the members of this group retain their mobility after metamorphosis, and hence, may depend less on enviromental cues...

La fauna de caprélidos (Crustacea: Amphipoda: Caprellidea) de la costa de Coquimbo, centro-norte de Chile, con una clave taxonómica para la identificación de las especies
Provedor de dados: 97
Autores: GUERRA-GARCÍA,JOSÉ M.; THIEL,MARTIN.
Los caprélidos son comunes y abundantes en muchos hábitats litorales del ambiente marino. Sin embargo este grupo de anfípodos no ha sido muy bien estudiado en la costa chilena. El estudio de los caprélidos se ha visto dificultado por su gran variabilidad morfológica y el hecho de que la literatura así como los especímenes de los museos son difíciles de localizar. El objetivo de este estudio fue entregar las herramientas taxonómicas para la identificación de las especies de crustáceos caprélidos comunes en el centro-norte de la costa de Chile. Se muestrearon distintos hábitats (boyas, bolones intermareales, praderas de algas y fanerógamas marinas) y se encontraron seis especies distintas de caprélidos: Caprellina longicollis (Nicolet, 1849), Caprella...

The distribution of littoral caprellids (Crustacea: Amphipoda: Caprellidea) along the Pacific coast of continental Chile
Provedor de dados: 97
Autores: THIEL,MARTIN; GUERRA-GARCÍA,JOSÉ M.; LANCELLOTTI,DOMINGO A.; VÁSQUEZ,NELSON.
Many littoral caprellid species have a very ample distribution, some having been reported from all over the world. The cosmopolitan distribution of many littoral caprellid species might be facilitated by the fact that they are often associated with fouling communities on floating objects, which have a high potential of far-range dispersal. This dispersal potential may also have implications for the distribution of caprellids on local and regional scales. Herein we examined the distribution of littoral caprellid species on two spatial scales, local (tens of kilometers) and regional (hundreds of kilometers) along the Pacific coast of continental Chile. On the local scale, we studied the caprellid fauna in different habitats (intertidal boulders, subtidal...

Ultrastructure of spermatozoa of the crab Ucides cordatus Linnaeus, 1763 is described and illustrated. Three parts can be distinguished: 1. the elongate-ovoid acrosome located anteriorly; 2. the cytoplasmic region; and 3. the nuclear region. The acrosome is composed of a thick electron-dense wall and a less electron-dense subacrosomal space. The cytoplasm region connects the acrosome with the nucleus, and three arms filled with microtubules arise from this region. The nucleus is polymorphous. The spermatozoon of Ucides cordatus follows the general pattern described for other Decapods.

Ovigerous females of Arenaeus cribrarius were collected at Ubatuba, São Paulo, and maintaining in aquaria under controlled temperature (25±1ºC), salinity (35±1‰) and photoperiod (12:12). A small sample of eggs was collected for each 24h, for morphological description, chromatic changes and biometric analysis throughout the embryonic development. Eight egg stages were photographed and had their small and large diameters measured under a microscope provided with camera lucida. The egg's shape was low elliptical during all the embryogenesis and showed size increase (24.4%) and volume (91.1 %), when the last stage were compared with the first one. According to mean egg diameter and volume, the eggs should be pooled in three different groups (1-3; 4-6; 7-8)...

Autores: Melo-Filho,Gustavo A.S. de; Melo,Gustavo A.S. de.
The purpose of this work is to analyse the taxonomy and distributional patterns of the species of the genus Munida Leach, 1820 which occur along the Brazilian coast. The species of Munida present some peculiar characteristics, rarely found in any other marine group. They live in groups with great number of individuals (gregariousness) and with several species found together in the same population (sintopy). In addition, they exhibit a great degree of intraspeciftc variation and, paradoxally, a little variability among the species. These factors make a better understanding of the systematics of this group very difficult. In the present study the utilization of non variable characters was emphasized. As a corollary of this study, "species-complexes" were...

Autores: Nogueira Júnior,Miodeli; Haddad,Maria A.
Associations between jellyfish and other organisms are frequently reported. Neverhteless, few of those records include crabs inhabiting medusae. Lychnorhiza lucerna Haeckel, 1888 were sampled (n = 1988) on the coast of the State of Paraná (25º20'-25º55'S, 48º10'-48º35'W), southern Brazil, from December 1997 to December 2004. Eight percent (166 individuals) of the medusae had one spider crab Libinia ferreirae Brito Capello, 1871 living within its subgenital porticus or on the oral arms. Megalopal stages of the same crab were also found on three jellyfish. All crabs associated with L. lucerna were young and smaller (&lt; 3 cm) than solitary crabs caught on the bottom. Thus, L. ferreirae probably colonizes the jellyfish as a late larva and uses it as a...

The growth study, in length and weight, of Aegla leptodactyla Buckup &amp;amp; Rossi, 1977, was developed based on biometric data of 2,435 specimens collected from Rio da Divisa, a tributary of the Rio Silveira, district of São José dos Ausentes, Rio Grande do Sul State, Brazil. The samplings were realized from April/2000 to July/2001. The captured specimens had recorded the Sex and the length and width of cephalothorax. The specimens from June/2000, November and May/2001 were weighted, and those from June and July/2001 had recorded their length and width of the chelipeds. For the description of the growth the von Bertalanffy's model was utilized. The growth curves in length (mm), for data obtained through the modal progression, are described by the...

Efeito da densidade populacional sobre as curvas de crescimento de Macrobrachium rosenbergii (De Man) em cultivo semi-intensivo (Crustacea, Palaemonidae)
Provedor de dados: 104
Autores: Valenti,Wagner Cotroni; Mello,Jeanette de Toledo Cardoso de; Castagnolli,Newton.
In this article the length growth curves of Macrobrachium rosenbergii (De Man, 1879) held in different population densities were analysed. Postlarvae prawns were stocked into five 0,02 ha earthen ponds at densities of 4, 8, 12, 16 and 20 ind./m² during six months. Forthnightly, the mean total length of animals from each pond were obtained by means of random samples. For each population the length growth curves and the instantaneous growth rate expressions were determined. The growth rate and the asymptotic maximum length decreased with the stocking density raised. This effect is greater when the density ranges in low levels. The growth decrease can be due to intraspecific competition for life resources and to negative interactions between individuals, as...

The overall mean density of the copepods was 9,085 ind.m-3 with the peaks exceeding 15,000 ind.m-3 in the summer and autumn during the first three years (1993 - 1995). The PCA analysis was used to relate the environmental conditions with the distribution of the copepods. The increases in the abundant species, namely Acartia lilljeborgi, Oithona hebes, Oithona oculata, Paracalanus quasimodo, Parvocalanus crassirostris and Euterpina...

The present study analyzed the growth of males and females of the hermit crab Clibanarius vittatus (Bosc, 1802), at São Vicente, São Paulo, Brazil. Monthly collections were made from May/2001 through April/2003, at the Pescadores Beach in São Vicente. The 2,501 crabs caught were identified and sexed and the carapace shield length (CSL) was measured. For the seasonal growth study, the population was divided into 5mm size classes (CSL) and analyzed by the Bertalanffy method, with the aid of the program Fisat II. The mean sizes of the 703 males and 1,798 females were 8.94±1.80 and 6.61±1.13 mm, respectively. A seasonal growth pattern was observed, with males reaching an asymptotic size (14.92 mm) larger than that of females (13.85 mm). Males began the growth...

Natural diet of Neohelice granulata (Dana, 1851) (Crustacea, Varunidae) in two salt marshes of the estuarine region of the Lagoa dos Patos lagoon
Provedor de dados: 52
Autores: Barutot,Roberta Araujo; D'Incao,Fernando; Fonseca,Duane Barros.
Natural diet of Neohelice granulata in two salt marshes of Lagoa dos Patos, RS were studied. Sampling was performed seasonally and crabs were captured by hand by three persons during one hour, fixed in formaldehyde (4%) during 24 h, transferred to alcohol (70%). Each foregut was weighed and repletion level was determined. Differences between sexes in the frequencies of occurrence of items were tested by χ2test. A total of 452 guts were analyzed. Quali-quantitative analyses were calculated following the method of relative frequency occurrence and relative frequency of the points. At both sites, for both sexes and in all seasons, the main food items were sediment, Spartina sp. and plant detritus. The highest values of mean repletion index were estimated for...

Reproductive pattern comparison of Uca thayeri Rathbun, 1900 and U. uruguayensis Nobili, 1901 (Crustacea, Decapoda, Ocypodidae)
Provedor de dados: 52
Autores: Costa,Tânia Marcia; Silva,Stella Maris Januário; Negreiros-Fransozo,Maria Lucia.
Ovigerous females of Uca thayeri and U. uruguayensis were used to achieve and compare their reproductive pattern. The females mean size was 6.6 ± 0.8mm for U. uruguayensis and 17.3± 4.4mm for U. thayeri. The mean fecundity obtained for U. uruguayensis was 1883 ± 490 eggs (N = 27) and for U. thayeri was 31068 ± 11186 eggs (N = 31). The differences observed in reproductive pattern of U. thayeri and U. uruguayensis suggest an adaptive strategy by each species: U. thayeri presented seasonal reproduction with a pronounced intensity from January to March and higher fecundity, while U. uruguayensis reproduction was continuous all year round, but with lower fecundity.

Larvae and post-larvae of Penaeidae and Palaemonidae in coastal lagoons of the North of Rio de Janeiro (Macaé, RJ)
Provedor de dados: 57
Autores: ALBERTONI,E. F.; PALMA-SILVA,C.; ESTEVES,F. A.
The northern part of the state of Rio de Janeiro shelters many coastal lagoons, located, mostly, in the "restinga" strip that stretches from the municipality of Macaé to the municipality of Quissamã. During 1995 and 1996 samplings were made aiming to verify the diversity and density of Natantia larvae in the Imboassica, Cabiúnas and Comprida lagoons. The monthly samples were taken with a 500 µ net, in horizontal drags from a boat. In Comprida lagoon no larvae of any family of these crustaceans were found. In Cabiúnas lagoon, the autumn was the season of the year with greatest relative abundance, the larvae belonging to only one genus: Macrobrachium. In Imboassica Lagoon samples were taken in two situations related to the variation of the water level and...

Em lavoura de arroz irrigado, é utilizada uma grande quantidade de agroquímicos que, dependendo da sua persistência a campo e toxicidade, podem contaminar corpos d’água e afetar organismos vivos. Com o objetivo de determinar o efeito de concentrações de campo dos herbicidas Clomazone, Quinclorac, Metsulfuron-methyl e Propanil na comunidade zooplanctônica (Cladocera, Copepoda e Rotifera), conduziu-se um experimento em viveiros de aqüicultura, de março a maio de 2005, na estação do outono. Nos dias 1°, 2°, 3°, 7°, 10°, 18°, 31° e 51° após a aplicação dos herbicidas, foram coletadas amostras de água para se determinarem parâmetros físico-químicos da água, concentração dos herbicidas e comunidade zooplanctônica. Os parâmetros médios da qualidade da água foram:...
