Anoplosyllinae y Eusyllinae (Polychaeta: Syllidae) del Gran Caribe, con comentarios sobre materiales tipo y no tipo

Zaabi-Sendi, Sana.

The polychaetes communities structure and functioning of the Cap Bon peninsula (Northeast coast of Tunisia), were analyzed from 52 stations from Sidi Daoud to Menzel Horr. The faunistic study reveals the presence of 238 polychaetes species among which 86 records are newly reported for the Tunisian coasts. The total number of polychaetes listed in Tunisia rises to 375 species. The polychaete community structure at the sites was examined by multivariate methods. five main polychaetes communities were identified in the study area, the sandy sediment community (SS), the muddy sediments community (SV), the coarse sediment community (SG), the fine-muddy sediment community (SFV) and the Heterogeneous sediments community (HS). These communities are distributed...

Significations ecologiques de la variabilite des polychetes dans le golfe de Tunis

Ruiz Ramírez, J. D..

La subfamilia Anoplosyllinae posee palpos fusionados en la base, sin surco central, tres antenas y dos pares de cirros tentaculares, faringe recta, corta y desarmada. Antenas, cirros tentaculares y primeros cirros dorsales lisos, el resto pueden ser lisos o semiarticulados. La subfamilia Eusyllinae posee palpos fusionados, parcialmente o libres, órganos nucales frecuentemente largos y diferenciados, uno o dos pares de cirros tentaculares, cirros dorsales que varían en longitud, usualmente lisos, cirro ventral presente, faringe usualmente derecha, con dientes o inerme. El objetivo de este estudio fue revisar material tipo y no tipo de las especies registradas para el Gran Caribe. Fueron examinados 186 ejemplares; 135 colectados en el Caribe mexicano y 51...

Ecología trófica del gatuzo, Mustellus schmitti (Springer 1939), en el Mar Argentino

Zaabi, S.; Afli, A..

The coastal areas, like the gulf of Tunis, are more and more affected by the increasing anthropic activities and nutriment inputs coming from the catchments area. The polychaeta populations show different reactions in front of such conditions and constitute an effective biological tool to detect the first signs of disturbance. In total, nine stations in the north-east of the gulf, were sampled by the Van Veen grab. In this study, the model of ecological groups and biotic index was used. It appears that the general state in the studied area is overall satisfactory, except for some ones where a situation of beginning of imbalance or of transition, seems taking place.

Fósseis do Devoniano de Goiás, Brasil (Sub-bacia Alto Garças, Bacia do Paraná)

Belleggia, M..

The narrownose smoothhound shark Mustelus schmitti is a benthic shark distributed from Florianópolis (27°S, Brazil) to Deseado River Estuary (47º45´S, Argentina) and occurs from shallow waters to 120m. This Thesis describes the feeding ecology of narrownose smoothhound shark M. schmitti in northern Argentinean Continental Shelf and is structured in four chapters. Chapter 1 contains an introduction and includes purpose, theory and concepts. In Chapter 2, the food habits of M. schmitti were studied based on analysis of stomach contents from specimens collected during the years 2008-2011. Of a total of 959 stomachs sampled during this period, 944 (98,43%) contained food. Prey items were identified to the lowest possible taxonomic level, counted and weighted....

RESUMO O registro fóssil do Devoniano do estado de Goiás (Sub-bacia Alto Garças, Bacia do Paraná) é ocorrente nos arredores de diversas cidades como Amorinópolis, Iporá, Caiapônia, Rio Verde e Doverlândia. Contudo, os fósseis encontrados em Goiás são, em sua maioria, representados por braquiópodes, comumente pertencentes aos gêneros Derbyina, Australocoelia, Australospirifer, Schuchertella, Orbiculoidea e Lingula. Embora também haja ocorrências, em menor número, de outros grupos como trilobitas, moluscos, tentaculitoideos, anelídeos, equinodermas, lycopsidas e cnidários, além dos microfósseis de quitinozoários, representados pelos gêneros Ramochitina, Ancyrochitina, Sphaerochitina, Angochitina, Conochitina, Lagenochitina e Cyathochitina. No entanto, os...

ABSTRACT We re-assess the taxonomic status of Owenia Delle Chiaje, 1841 from Southern Brazil based on estuarine specimens from Paranaguá Bay (Paraná) and Babitonga Bay (Santa Catarina), and literature records. Owenia caissara sp. n. is diagnosed by a branchial crown with five pairs of tentacles, branched close to the base of the crown, rectilinear collar with a pronounced lateral slit, two ventrolateral ocelli partially covered by the collar, up to 23 hooks on a single row in the first abdominal segment, regularly curved nuchal shape, regularly moderate teeth curvature, and long and thin scales with oval transition. The description of Owenia caissara sp. n. reinforces the idea that Owenia fusiformis sensu lato is a complex of closely related species that...

This study is based on the identification and distribution of spionid polychaetes in relation to abiotic characteristics of the environment at the mouth of the Valdivia-Tornagaleones estuary in south-central Chile. Four samplings were carried out in 2005, in which eight species were identified including Aquilaspio peruana, Boccardia polybranchia, Carazziella carrascoi, Dipolydora socialis, Minuspio patagónica, Rhynchospio glutaea, Scolelepis quinquedentata and Spiophanes sp. As it is typical of other estuaries in south central Chile, spionids were an important component of the macroinfauna of the Valdivia estuary. The distribution of the Spionidae family in the system showed higher species richness in the outer reach of the estuary but higher abundance...

Eunice rubra Grube (Annelida, Polychaeta, Eunicidae), a redescription based on the holotype and Brazilian specimens

Steiner,Tatiana Menchini; Nogueira,João M. de M.; Amaral,A. Cecília Z..

Based on features of the holotype and seven Brazilian specimens examined under stereomicroscope, light microscope, and scanning electron microscope, Eunice rubra Grube, 1856 is redescribed, allowing for intraspecific variation and providing informationon characters not included in a previous redescription. Characters important for the taxonomy of the genus varied widely, although in some cases because of fixation artefacts.

Polychaetes are metameric worms recognized for having parapodia, chaetae, and nuchal organs. Some authors have extended the Annelida to include Pogonophora, Echiura, and Clitellata. These suggestions are insufficient to generate a monophyletic group. They do not take into account two very large and important clades that in a cladistic analysis at a higher level are shown to be nested within the Annelida: the Ecdysozoa (arthropods and related taxa) and Enterocoela (deuterostomes and related taxa). Evolutionary histories of most characters across metazoan phyla are still very poorly known. Metameres and coeloms have been considered homoplastic in the literature, and yet the homeobox genes responsible for the expression of metamerism and of paired appendages,...

Sene-Silva,Gustavo.

The Oweniidae consist of five genera of tubiculous polychaetes occurring in all oceans from tropical topolarareas: Owenia Delle Chiaje, 1842, Myriochele Malmgren, 1867, Galathowenia Kirkegaard, 1959, Myriowenia Hartrnan, 1960 and Myrioglobula Hartrnan, 1967. The group is regarded as monophyletic based on the presence of dense fields of bidentate neuropodial hooks. Fourteen species were submitted to a cladistic analysis in PAUP 3.1.1 with the usage of 19 morphological characters.The taxonomic status of the ingroup taxa could be evaluated and it has been found that: (1) Owenia, Myriowenia and Myrioglobula are monophyletic, and (2) Myriochele, and Galathowenia are both paraphyletic taxa.
