This study aims to describe the patterns of soft bottom macrozoobenthic richness along French coasts. It is based on a collaborative database developed by the “Réseau des Stations et Observatoires Marins” (RESOMAR). We investigated patterns of species richness in sublittoral soft bottom habitats (EUNIS level 3) at two different spatial scales: 1) seaboards: English Channel, Bay of Biscay and Mediterranean Sea and 2) 0.5° latitudinal and longitudinal grid. Total observed richness, rarefaction curves and three incidence-based richness estimators (Chao2, ICE and Jacknife1) were used to compare soft bottom habitats species richness in each seaboard. Overall, the Mediterranean Sea has the highest richness and despite higher sampling effort, the English Channel...

Based on a parallel sampling conducted during autumn 2008, a comparative study of the intertidal benthic macrofauna among 10 estuarine systems located along the Channel and Atlantic coasts of France was performed in order to assess the level of fauna similarity among these sites and to identify possible environmental factors involved in the observed pattern at both large (among sites) and smaller (benthic assemblages) scales. More precisely this study focused on unraveling the observed pattern of intertidal benthic fauna composition and diversity observed at among-sites scale by exploring both biotic and abiotic factors acting at the among- and within-site scales. Results showed limited level of similarity at the among-site level in terms of intertidal...

A new species of Pista Malmgren, 1866 (Polychaeta, Terebellidae) from the north-western Mediterranean Sea
Provedor de dados: 5
Autores: Labrune, Céline; Lavesque, Nicolas; Bonifácio, Paulo; Hutchings, Pat.
A new species of Terebellidae, Pista colini sp. n., has been identified from the harbour of Banyuls-sur-Mer, north-western Mediterranean Sea. This new species was found in very high densities, exclusively in gravelly sand deposited manually, and was not found in the original source habitat of the gravel. This species is characterized by the colour of the ventral shields with pinkish anterior part and a blood red posterior part in live specimens, a pair of unequal-sized plumose branchiae inserted on segment II and anterior thoracic neuropodia with long-handled uncini. The presence of long-handled uncini even in the smallest specimens constitutes the major difference between Pista colini sp. n. and other Pista species with a single pair of branchiae such as...

La sole est la ressource halieutique qui contribue le plus aux débarquements en valeur des pêches réalisées dans le golfe de Gascogne (52 M € en 2007-09). Elle arrive aussi en première place dans les débarquements de la pêche charentaise (8 M € en 2007-09). Une flottille de grands fileyeurs spécialisés dans sa pêche s'est développée dans le golfe de Gascogne, dont certaines des unités les plus performantes sont basées à Royan. Le port de La Cotinière est l'un des premiers pour les débarquements de sole des chalutiers opérant dans le golfe de Gascogne. Cette espèce contribue aussi à l'équilibre financier annuel de nombreux petits bateaux côtiers.

A new species of the Marphysa sanguinea complex from French waters (Bay of Biscay, NE Atlantic) (Annelida, Eunicidae)
Provedor de dados: 5
Autores: Lavesque, Nicolas; Daffe, Guillemine; Bonifacio, Paulo; Hutchings, Pat.
A new species of Eunicidae, Marphysa victori sp. n., has been identified from Arcachon Bay, Bay of Biscay, NE Atlantic. This new species, belonging to the sanguinea complex, is characterised by branchiae with long filaments from chaetigers 26–34, the presence of four types of pectinate chaetae with first ones present from chaetiger 2, a large number of both pectinate chaetae and compound spinigers, and the pygidium with only one pair of pygidial cirri. An identification key for European species of the genus Marphysa is provided.

Within the COST action EMBOS (European Marine Biodiversity Observatory System) the degree and variation of the diversity and densities of soft-bottom communities from the lower intertidal or the shallow subtidal was measured at 28 marine sites along the European coastline (Baltic, Atlantic, Mediterranean) using jointly agreed and harmonized protocols, tools and indicators. The hypothesis tested was that the diversity for all taxonomic groups would decrease with increasing latitude. The EMBOS system delivered accurate and comparable data on the diversity and densities of the soft sediment macrozoobenthic community over a large-scale gradient along the European coastline. In contrast to general biogeographic theory, species diversity showed no linear...

Use of biotic indices in semi-enclosed coastal ecosystems and transitional waters habitats - Implications for the implementation of the European Water Framework Directive
Provedor de dados: 5

This study deals with the application of macrozoobenthos-based biotic indices (BI) within the frame of the implementation of the European Water Framework Directive. More precisely, this study aimed at assessing the performance of five recently developed methodologies (BI) for the assessment of ecological quality status (EcoQ) in two semi-enclosed, sheltered coastal ecosystems and in one transitional water body situated along the Western French coast, namely Marennes-Oleron Bay, Arcachon Bay, and the Seine Estuary. This study showed that these five indices rarely agreed with each other, describing very different pictures of the overall EcoQ of the three study sites. This work also clearly underlined the limitations of these approaches, notably the...

Recent expansion of the oriental shrimp Palaemon macrodactylus (Crustacea: Decapoda) on the western coasts of France
Provedor de dados: 5
Autores: Lavesque, Nicolas; Bachelet, Guy; Beguer, Melanie; Girardin, Michel; Lepage, Mario; Blanchet, Hugues; Sorbe, Jean-claude; Moderan, Julien; Sauriau, Pierre-guy; Auby, Isabelle.
The invasive oriental shrimp Palaemon macrodactylus Rathbun, 1902 has considerably extended its distribution in transitional waters along the Atlantic and Channel coasts of France during the period 2007-2010. The most probable method of a primary introduction of this species is ballast waters, but passive transport by water currents is also a possible mechanism of colonization (secondary introductions). Palaemon macrodactylus is a powerful invader of transitional waters and these new populations should be monitored in the future to assess any consequences to native species.

Provedor de dados: 5
Autores: Lavesque, Nicolas; Bonifacio, Paulo; Londono-mesa, Mario H.; Le Garrec, Vincent; Grall, Jacques.
A new species of Terebellidae, Loimia ramzega sp. nov., has been identified from North Brittany beaches (English Channel). This new species is characterized by its gigantic size (max 650 mm, live), two pairs of lateral lappets on segments 1 and 3; first pair more ventral, second pair more developed and lateral but oblique, with wavy edge. Nine ventral pads from segment 2 (fused on segments 2 and 3), first three pads swollen, next ones subsequently decreasing in size. Three types of notochaetae, asymmetrically bilimbate, symmetrically bilimbate and capillary. Uncini pectinate with 6 teeth (some with 5 teeth) slightly decreasing in size, in one vertical row. Pygidium with about 14 long conical marginal papillae surrounding anus.

The Terebelliformia-Recent Developments and Future Directions
Provedor de dados: 5
Autores: Hutchings, Pat; Carrerette, Orlemir; Nogueira, João M. M.; Hourdez, Stephane; Lavesque, Nicolas.
Terebelliformia comprises a large group of sedentary polychaetes which live from the intertidal to the deep sea. The majority live in tubes and are selective deposit feeders. This study synthesises the current knowledge of this group, including their distribution, in the different biogeographic regions. We highlight the new methodologies being used to describe them and the resolution of species complexes occurring in the group. The main aim of this review is to highlight the knowledge gaps and to stimulate research in those directions, which will allow for knowledge of their distribution and abundances to be used by ecologists and managers.
