Les noms propres dans les Élégies d’André Chénier

Agnès Steuckardt
Comment expliquer la haute fréquence des noms propres dans les Élégies ? Après avoir mis en évidence leur surabondance, on montrera d’abord qu’elle est due à un empiètement du nom propre sur le territoire du nom commun : par leur production de sens, par leurs emplois métaphoriques ou métonymiques, des noms originellement propres assument des fonctions sémantiques ordinairement dévolues au nom commun. Si l’on perçoit bien dès lors comment les noms propres envahissent le discours...

Note on the association between Plakobranchus ocellatus (Mollusca: Gastropoda: Opisthobranchia) and Holothuria atra (Echinodermata: Holothuroidea)

Annie MERCIER & Jean-François HAMEL
This paper presents evidence of a commensal association between an opisthobranch (Plakobranchus ocellatus) and a sea cucumber (Holothuria atra). Field observations revealed that occurrences of P. ocellatus specimens and egg fil- aments were much more frequent on the body wall of H. atra than on that of two other holothurian species living in the same habitat. Roughly 95% of H. atra were colonized by P. ocellatus during the night, which corresponds to the active period...

A re-description of Periclimenaeus robustus Borradaile, the type species of the genus Periclimenaeus Borradaile, 1915 (Crustacea: Decapoda: Pontoniinae)

Alexander J. BRUCE
The type material of the pontoniine shrimp Periclimenaeus robustus Borradaile, 1915, is re-examined and the specimens re-described and illustrated. This species is the type species of the genus Periclimenaeus Borradaile, 1915, the second most speciose pontoniine genus, and is known only from the type material, which is now found to consist of two Periclimenaeus species.

Cliona microstrongylata, a new species of boring sponge from the Sea of Cortés (Pacific Ocean, México)

José Luis CARBALLO & José Antonio CRUZ-BARRAZA
A new species of excavating sponge of the family Clionaidae, Cliona microstrongylata sp. nov. was found in detritic bottoms from the Sea of Cortes at 26 m depth. The type grows in alpha stage boring a dead bivalve shell. It pres- ents very small orange-red papillae (from 150 to 850 µm in diameter), which are regularly distributed on the surface of the shell. They are level with the surface of the substratum and don't fuse....

Two new species and one new record of free-living marine nematodes from the Yellow Sea, China

Yong HUANG & Zhinan ZHANG
Two new species and one new record of free-living marine nematodes: Terschellingia major sp. nov., Halalaimus longamphidus sp. nov. and Paramicrolaimus mirus Tchesunov, 1988 from the Yellow Sea, China are described. Terschellingia major sp. nov. is characterized by large body size, papilliform precloacal supplements and absence of pos- terior bulb; Halalaimus longamphidus sp. nov. is characterized by very long amphids (more than 70 µm) and long bifid tip of tail. Paramicrolaimus mirus Tchesunov is redescribed...

Aquilastacus gen. nov. from the southern North Sea and the taxonomic position of Leptastacus operculatus Masry, 1970 (Copepoda: Harpacticoida: Leptastacidae)

A new genus of Leptastacidae (Copepoda: Harpacticoida) is described from subtidal sandy sediments in the Southern Bight of the North Sea. Aquilastacus serratus gen. nov. sp. nov. is most closely related to Arenocaris Nicholls with which it shares the unique sexual dimorphism on the P4 endopod, the distally constricted caudal rami and the loss of the subdistal spine on the P3 endopod in the female (and hence of the sexual dimorphism in the male). The...

Annual cycle of microphytoplankton from the coasts of the tropical Mexican Pacific

Despite the length of littorals, studies of annual cycles for phytoplankton in the Mexican Pacific are rare, espe- cially in tropical areas. A study of the phytoplankton (basically microphytoplankton) was realized in six locations off the States of Jalisco and Colima, from June, 2001 to May, 2002. A total of 286 taxa belonging to the taxonomic groups diatoms, dinoflagellates, cyanophyceae and silicoflagellates were identified. The best represented groups were dinoflagellates (157 taxa) and diatoms (119...

Seasonal variability of planktonic copepods in Tunis North Lagoon (Tunisia, North Africa)

Neila ANNABI-TRABELSI, Mohamed Néjib DALY-YAHIA & Mohamed Salah ROMDHANE
This paper describes temporal and seasonal variations in the composition and abundance of the planktonic cope- pod community in the North lagoon of Tunis and the influence of selected environmental factors (temperature, salinity, sus- pended particulate matter and chlorophyll a concentrations) on this community. Samples were collected weekly from March 2001 to September 2002. Total planktonic copepod abundance showed low densities and high variability, lacking any clear seasonal pattern. In total, 24 species were identified....

Characterization of an actin gene family in Palmaria palmata and Porphyra purpurea (Rhodophyta)

Line LE GALL, Christophe LELONG, Anne-Marie RUSIG & Pascal FAVREL
The actin gene family was investigated in Palmaria palmata and Porphyra purpurea, two members of the Rhodoplantae. Respectively four and two partial actin gene sequences were isolated from P. purpurea and P. palmata by PCR using actin primers deduced from the conserved regions of many classes of organisms. In P. purpurea, the partial actin gene puract1, puract2 and puract3 were shown to code for proteins whereas puract4 is a pseudogene. This result confirms the presence...

Rediscovery of Coryne fucicola (de Filippi, 1866) (Cnidaria: Hydrozoa)

Coryne fucicola (de Filippi, 1866) has been considered a somewhat problematic species of unknown origin and whose last records date back more than a century. However, a living colony was recently rediscovered at Roscoff and the species is redescribed in this report. It is evidently a valid species and clearly distinct from other similar species like Coryne pusilla and C. muscoides. This was also confirmed using 16S sequence data. The relationship to the similarly problematic...

First record of Trunculariopsis trunculus (Linnaeus, 1758) (Mollusca: Gastropoda) from the basin of Arcachon (Gironde): the second exotic muricid on the French Atlantic coast

The species Trunculariopsis trunculus (Linnaeus, 1758) is first recorded in the basin of Arcachon (Gironde, France). Eight living specimens, of which three are illustrated here, were collected in 1996/1997, 2002, 2003 and 2004, at 3 to 5 meters deep in the Courbey channel, close to the city of Lège-Cap-Ferret. They reach a large size (84-105 mm in height) and correspond to adult individuals. Thus, this record shows the occurrence of a second exotic muricid on...

The mollusc community associated with maerl beds of Ustica Island (Tyrrhenian Sea)

Living molluscs associated with circalittoral maerl have been studied at Ustica Island (southern Tyrrhenian Sea). Five sediment samples from two sites were collected in November 1996 and July 1997 using a van Veen grab (0.1 m2), at 50 m depth. Two-way crossed PERMANOVA revealed non-significant temporal and spatial differences in abundance. The molluscan community was composed of both hard bottom and soft bottom species typical of circalittoral coastal detritic and to coarse sands and fine...

Upper littoral rhombognathines (Acari: Halacaridae) of Singapore: description of three new species

Abstract: Three rhombognathine species are described, species which predominate in the upper tidal area, in a zone not regularly submerged during every tidal cycle. The three species are Isobactrus similis sp. nov., Rhombognathus bulbosus sp. nov. and R. major sp. nov. Isobactrus similis inhabits barnacle colonies on rocks, Rhombognathus bulbosus patches of green algae on stems of mangroves and R. major algal turfs on rocky cliffs.

Tapas CHATTERJEE & Cheon Young CHANG2
3A new species of halacarid mite belonging to the genus Copidognathus viz. C. fistulosus is described on the basis of specimens collected from an algal bed in Jeju Island, South Korea. Copidognathus fistulosus sp. nov. is closely related to C. koreanus Chatterjee & Chang and C. laevisetosus Chatterjee, Lee & Chang. Morphological similarities and dissimilarities among them are discussed.

Polychaete assemblages on shallow-water benthic habitats along the Sinop Peninsula (Black Sea, Turkey)

The present study describes polychaete assemblages on three shallow-water benthic habitats, Ulva rigida, Cytoseira barbata and Mytilus galloprovincialis, in relation to space and time from the Sinop Peninsula (Turkish Black Sea coast). A total of 55 polychaete species and 21493 individuals belonging to 16 families were identified. Among the species, eight are reported for the first time from the Black Sea and 29 species from the Turkish Black Sea coasts. The polychaete density in the...

Bacterioplankton growth on extracellular organic carbon from marine microalgal cultures

Konstantinos Ar. KORMAS
Marine bacterial growth on extracellular organic carbon (EOC) of Chlorella minutissima, Dunaliella tertiolecta and Chaetoceros gracilis was studied. EOC was retrieved after filtration of optimum growing algal cultures at the middle of the exponential growth phase and the stationary phase. The filtrates were inoculated with natural marine bacterial assem- blages. The batch cultures were monitored for dissolved organic carbon (DOC) concentrations, bacterial yield, biomass and oxygen respiration over a period 3.5-10 days. The overall bacterial...

Holoplanktonic polychaetes from the Gulf of Tehuantepec, Mexico

Composition, abundance, and main assemblages of holoplanktonic polychaetes were analysed in the Gulf of Tehuantepec. This Gulf, in Mexican waters of the eastern tropical Pacific, is a very productive system due to an upwelling during the winter. Zooplankton samples were taken over a station grid covering neritic and oceanic waters during March and November 1978. Most species showed their highest densities in the oceanic region. In the western Gulf, the area sam- pled in both...

Alimentation et condition de la dorade Sparus aurata (Teleostei: Sparidae) dans la lagune du Mellah (Algérie Nord-Est)

Lamya CHAOU, Farid DERBAL, M. Hichem KARA & Jean Pierre QUIGNARD
Dietary habits and condition of gilt-head sea bream Sparus aurata (Teleostei: Sparidae) in the Mellah lagoon (North-Eastern Algeria). The feeding habits of Sparus aurata in the Mellah lagoon (northeastern Algeria) was studied using three simple methods (frequency of occurrence of prey, numeric percentage and percentage weight) and a feeding coeffi- cient. Monthly variations in the stomach vacuity were also examined. The diet includes a wide variety of food organisms, fish and molluscs bivalvia constituting the...

Drifting branches of Crambe maritimaL. with fruits

Gerhard C. CADÉE
The observation of dried branches of Crambe maritima L. in drift along the shore, with fruits still attached, indi- cates dispersal by the sea of this coastal plant is not restricted to single drifting fruits, but also occurs as drifting branches with the fruits still attached. Along the shore such branches are transported further by the wind as "tumble-weeds", losing their fruits during tumbling.

Palaemonella burnsi Holthuis, 1973, a pontoniine shrimp (Crustacea: Decapoda: Palaemonidae) new to the Japanese fauna

Alexander J. BRUCE
The pontoniine shrimp, Palaemonella burnsi, is recorded for the first time outside the Hawaiian Islands. The single specimen, from the Ryukyu Islands, Japan, indicates a considerable extension of the species distribution, that it is not an endemic Hawaiian species, and that it may occur in pools on coral reef flats and is not restricted to anchialine habi- tats.

Taxonomy of Oncaeidae (Copepoda: Cyclopoida) from the Red Sea. VII. Oncaea cristata, a new species related to the ovalis…complex, and a revision of O. ovalis Shmeleva and O. bathyalis Shmeleva from the Mediterranean

A new small species of oncaeid copepod, Oncaea cristata, is described from the mesopelagic zone of the Red Sea. The species is characterized by a very small outer distal spine on the endopods of swimming legs 2 and 3, being shor- ter than the terminal conical projection on the distal segment. Females of an oncaeid species sharing this distinct morpho- logical character were described by Shmeleva (1969) from the Adriatic Sea under the name O....
