Programme Expérimental de Réhabilitation des Fossés à Poissons (1997-2000)

Truquet, Philippe; Lassus, Patrick; Honsell, Giorgio; Le Dean, Loic.

An image discrimination technique was developed to improve specific identification of some toxic Dinophysis cells (marine dinoflagellates involved in diarrhoeic shellfish poisoning), especially the ''acuminata'' and ''sacculus'' groups, which can be present at different ratios in natural sea-water samples collected during toxic episodes. This work was performed with image analysis software SAMBA (TITN Alcatel) using preserved cells directly observed through an inverted microscope and recorded with a video camera before further processing. All morphometric parameters used for discrimination of 7 different species or morphotypes of Dinophysis were tested with discriminant analysis. This study indicates that Dinophysis sp. and D. pavillardi seem well...

Cette étude s'inscrit dans le cadre du programme expérimental de réhabilitation des fossés à poisson initié au CREAA (1997-2000). Ce programme répond à une demande régionale pour la valorisation des fossés à poissons. Cet écosystème fait partie du patrimoine régional et marque surtout son identité culturelle, une volonté locale a été manifestée pour sa conservation et valorisation. Cependant l'aménagement de ces structures s'avère très coûteux, le grossissement de poissons, essentiellement l'anguille, a été prévu afin de justifier les frais d'aménagement. Par ailleurs, l'élevage extensif de poisson s'accompagne de la pratique d'autres activités telle que l'agriculture ou l'élevage. La cohabitation de ces différents types d' activités peut déstabiliser le...

Structure des peuplements bactériens : approche méthodologique et premiers résultats en milieux lagunaires

Numération et approche qualitative des populations bactériennes des lagunes aménagées de Certes (Arcachon). I. Bactéries hétérotrophés aérobies

Troussellier, M; Baleux, B..

After the enumeration of hétérotrophie bacteria from mediterranean and atlantic lagoons water and sediment by means of cultural methods, the qualitative study of each bacteria is carried on with the help of the API 20 B standardized microbiological method. The distinctive characteristics of bacteria of each communities are coded so that to build matrix of binary data. The grouping of bacteria is realized by means of both linnean systematic and numerical taxonomy. The communities structure they constitute found expression in a systematic dominance index (D2), a Shannon taxonomic regularity index (J) and a "functionnal" regularity index (E). To have a better description and interpretation of the main ecological features of bacterial communities, it seems...

Taxonomie et virulence de vibrions pathogènes d'huîtres creuses Crassostrea gigas

Baleux, B.; Caumette, P.; Trousselier, M..

Numeration, biomass, distribution within time, some physiological characters and a taxonomical outline, with a standardized micro method, of aerobic hétérotrophie bacteria isolated from sediments an waters, from fishponds of "Domaine de Certes" (Arcachon) from june 1977 to may 1978 are described. Number of hétérotrophie bacteria evolved in a significant way, according to seasons, and bacterial biomass is higher in the sediments than in the waters. Metabolic or physiological differences (proteolysis, denitrification) appeared among populations due to the origin of sediments. Moreover the qualitative study pointed out taxonomical units as Bacillus associated to seasons, or Agrobacterium associated to vegetable detritical sediments.

Pleuronectidae de l'île de la Réunion et de Madagascar. I. Poecilopsetta

Le Roux, Frédérique.

As the emergence of new vibriosis in the European Atlantic coasts has been associated with mass mortalities of molluscs cuasing important economic losses, the project obectives are to provide knowledge and operational tools to evaluate the impact of vibriosis on farmed japenese oyster Crassostrea gigas. Facing the diversity of Vibrio species associated to bivalve disease outbreaks, the difficulties of identification and the detemrination of their pathogenic abilities we propose a double approach to correlate phenotype/geneotype of a bacteria with risk of disease : 1) by genotyping we will evaluate if specific strains are associated with disease. 2) by evaluating likely virulence mechanisms implicated in pathogenesis, we will characterise the genes...

A perspective on the census of marine life. The role of natural history institutions for this programme

Lapegue, Sylvie; Ben Salah, Inès; Batista, Frederico; Heurtebise, Serge; Neifar, Lassad; Boudry, Pierre.

Despite the economic importance of numerous oyster species throughout the world, our knowledge of their systematics and phylogeography remains fragmentary. In Europe, the indigenous species, Ostrea edulis, suffered overexploitation as well as two successive parasitosis over the last century. However, this species is still cultivated in Europe, and especially in Spain and France. Its distribution area stretches from the Atlantic coasts of Europe to the north of Africa as well as around the Mediterranean and Black Sea. Its Mediterranean and South Atlantic distribution area is shared with another indigenous species, the dwarf oyster, Ostreola stentina. Its very small adult size (a few centimetres) makes its culture pointless from a commercial point of view....

Bonamia ostreae, parasite de l'huître plate, Ostrea edulis: sa position taxonomique parmi les parasites du groupe "microcell", analyses des interactions hôte/parasite chez plusieurs populations d'huîtres plates

Pierrot-bults, Ac.

The Census of marine life programme (CoML) is expected to generate a large amount of information on the diversity, distribution, and abundance of marine communities, many of them new or poorly known. Institutions such as natural history museums can play a crucial role in providing the necessary tools to allow the CoML to advance knowledge in the fields of marine systematics and biogeography. These institutions can contribute taxonomic expertise to provide quality-controlled identifications of species; specimen collections to allow for cross-checking of occurrences and a historical context for new data; information, both paper and electronic, on taxonomy, ecology and other topics to enable researchers to review past work; education opportunities to inform...

Besnard-cochennec, Nathalie.

Bonamia ostreae is the causative agent of hemocyte disease. It has been detected first during mortalities occured in Franc in 1979. Bonamiosis spread rapidly among oysters farming in France and Europ. Another species, Bonamia sp. has been detected in New Zealand and Australia. These paasites were both included in the "microcell" group. This group contains 2 others parasites, Mikrocytos mackini affecting Crassostrea gigas in British Columbia (Canada) and M. roughleyi affecing Saccostrea glomerata in Australia. Structural and molecular caracterisation of all these parasites were realised. Results show tha B. ostreae, B. sp., B. exitiosus. Molecular tools are available for genus detection, Bonamia spp. and Mikrocytos and species identification (B. ostreae, B....

Efflorescences toxiques des eaux côtières françaises. Ecologie, écophysiologie, toxicologie

Berland, Brigitte; Lassus, Patrick.

Tandis que certa ines efflorescences micro-algales provoquent de sérieuses nuisances par leur développement exubérant, d'autres sont nocives en raison des toxines qu'elles produisent. Ces proliférations, dangereuses pour les organismes marins, mais aussi pour les consommateurs de fruits de mer, sont étudiées en France depuis 1983. Dès 1989, devant l'ampleur des phénomènes observés au niveau national et européen, un programme scientifique réunissant de nombreux in stituts et laboratoires, le PNEAT, a été créé afin de fédérer les moyens mis en oeuvre dans des disci plines aussi diverses que l'écologie, la biologie cellulaire, l'écophysiologie, la toxicologie et la chimie. Les résultats obtenus au cours de la période 1989-1995 sont présentés à la fois pour...

Taxonomie et phylogéographie des huîtres creuses dans l'Atlantique Sud

Three new genera and nine new species of the subfamily Candoninae (Crustacea, Ostracoda, Podocopida) from the Pilbara region (Western Australia)

Boutet, Isabelle.

L'étude de la taxonomie des huîtres est longtemps restée basée sur des critères morphologiques (forme de la coquille et description des organes) et géographiques. Ces considérations sont relativement peu fiables en particulier au niveau interspécifique du fait de la plasticité des caractères morphologiques d'une part de des introductions d'espèces étrangères sur les lieux de culture d'autre part. La biologie moléculaire est donc, depuis quelques années, un outil très utilisé pour différencier les espèces d'huîtres. La phylogéographie des huîtres de la région sud-atlantique a ainsi pu être étudiée grâce à différentes méthodes de recherche du polymorphisme réalisées sur le fragment mitochondrial 16S. La PCR-RFLP, la SSCP et le séquençage ont été utilisés...

Three new ostracod genera: Humphreyscandona n. gen., Pilbaracandona n. gen., and Notacandona n. gen., and nine new species are described from subterranean waters of the Pilbara Region, Western Australia. They belong to the subfamily Candoninae of the order Podocopida, and are characterized by a 5-segmented antennula and ornamented carapace. Humphreyscandona n. gen. contains five species, all with reduced posterior furcal claw and prominent external lobe on hemipenis. The other new genera each contain two species. Pilbaracandona n. gen. is also characterized by a reduced posterior furcal claw, but can be separated from the previous genus by the chaetotaxy of the antennula, mandibula, and general appearance of the hemipenis. Notacandona n. gen. is separated...

2012 is het jaar van de bij, in het leven geroepen vanwege de achteruitgang van zowel de wilde bijen als de honingbij. Doel van dit bijenjaar is meer aandacht te vragen voor deze belangrijke bestuivers in onze natuur en land- en tuinbouw. In dit bijenjaar is het verheugend te kunnen constateren dat Andrena rosae, één van onze ernstig bedreigde soorten wilde bijen, zich enigszins lijkt te herstellen.

The springtail Isotomurus maculatus new to the fauna of the Netherlands (Insecta: Collembola) Isotomurus maculatus (Schäffer, 1896) is a southern European springtail, which is recorded here as new for the fauna of the Netherlands. Specimens were collected on five sites in different regions of the Netherlands. The sites, a garden, a roadside verge and a lane with trees can be characterised as synatropic with a large degree of disturbance. In northern Europe Isotomurus maculatus is a eurytopic species that colonises ruderal sites very quickly. This conclusion is based on the description of the sites and the ecology of species collected together with I. maculatus. The distribution in Europe and the taxonomy of the species is described. It is argued that I....

Mol, A.W.M..

Athalia longifoliae is removed from synonymy with A. circularis and is upgraded to the species level from A. circularis ssp. longifoliae. The species is recorded for the first time for the Netherlands (19 localities) and for Germany (one locality). Differences between A. longifoliae and A. circularis are described and some notes on the ecology of A. longifoliae are given. In the Netherlands A. longifoliae was found only in a few limited areas where its host, Veronica longifolia grows, whereas A. circularis is common throughout the Netherlands. As both taxa occur within the same geographical area, do not interbreed and occupy their own ecological niche, these is no reason to treat A. longifoliae as a subspecies of A. circularis.

Motmuggen vormen een vast onderdeel van de fauna van de bebouwde omgeving. De larven leven veelal van organisch afval en de mugjes worden dan ook vaak in en om afvalbakken gezien. Het voorkomen van de verschillende soorten in deze biotoop worden besproken aan de hand van lichtvondsten van de auteur in Soest en door diverse personen binnenshuis verzamelde monsters, aangevuld met enkele handvangsten. Enkele taxonomische problemen binnen het genus Psychoda worden toegelicht en het overzicht over de verspreiding van de exoot Clogmia albipunctata wordt geactualiseerd. Vijftien tot twintig soorten zijn in de stedelijke biotoop gewoon, voor het overgrote deel behorende tot het genus Psychoda. Hiervan zijn P. albipennis, P. satchelli, P. cinerea, P. alternata en...

In the last decades, Van der Meijdenʼs editions of the Heukels’ Flora recognized only a single taxon in the 'Bolboschoenus maritimus group’ for the Netherlands: Bolboschoenus maritimus (L.) Palla, formerly known as Scirpus maritimus L. This is probably because the previously recognized infraspecific taxa were solely based on inflorescence architecture. These characters, however, vary between and within populations, and even within clones or individuals. However, in Central Europe the study of a new character, pericarp morphology, resulted in new insights in the taxonomy of the ‘Bolboschoenus maritimus group’. A species new to science, B. laticarpus Marhold, Hroudová, Ducháček & Zákr., has been reported to occur in the Netherlands as well. In this...

Review of the genus Psilota in the Netherlands (Diptera: Syrphidae) A review of the genus Psilota in the Netherlands is presented. It is demonstrated that the genus is represented by a complex of two species, Psilota anthracina Meigen, 1822 and P. atra (Fallén, 1817), as already indicated by Kassebeer. Both species can be separated using the key provided below. The interpretation of the species is exactly opposite to that in recent literature. Unfortunately, the holotype of P. atra Fallén was lost during transport. Therefore, we designate a neotype, again a male from Sweden (fig. 6). Our interpretation of the species is based on this neotype and the description and pictures of P. anthracina by Meigen. The habitats of both species in the Netherlands...
