Surveillance écologique et halieutique. Site de Gravelines. Novembre 1987 - Octobre 1988 ArchiMer
Delesmont, E; Delesmont, Régis; Delattre, J.m.; Grossel, Hubert; Le Fevre-lehoerff, Geneviève; Woehrling, Daniel; Martin, Jocelyne; Tetard, Alain; Dewarumez, Jean-marie; Menu, D..
Pendant la période Novembre 1987 - Octobre 1988, l'échauffement de l'eau dans le canal de rejet est équivalent à la période précédente (+ 8°C à + 8.5°C): Le taux de recyclage de l'eau calculé par rapport au bromoforme est de 4.3 %. Le bromoforme présente une valeur moyenne de 14 llg/1. La concentration moyenne annuelle de vibrions est 100 fois plus élevée au rejet qu'à la prise d'eau. La destruction de la biomasse chlorophyllienne due au transit est voisine de 50 % et celle de la biomasse zooplanctonique exprimée en carbone est d'environ 40 %. En 1988, les conditions météorologiques ont été favorables à la prolifération des Phaeocystis puis des noctiluques dans un milieu très eutrophisé. L'évolution des niveaux supérieurs de l'estran se confirme cette...

Les peuplements benthiques du plateau insulaire de la Martinique et des zones bathyales adjacentes. Cas particulier de la malacofaune ArchiMer
Paulmier, Gerard; Durand, Francoise.
Several oceanographic surveys in Martinique waters with, as main objectives, either geological mapping and evaluating marine aggregate resources of research into deep water carcinologie resources, nafe produced interesting informtion on benthic pppulations situated from the infralittoral to the bathyal shelf, for the wole of faunistic groups and more specifically for the malacofauna. The distribution of the various faunistic group has been analysed in function to the bathymetric, edaphic and possibly, thermic factors. The infralittoral zones, up to the 20 metres isobath, and circalittoral, between 60  and 80 metres, are known to have the richest populations. Corals, sponges, polychaete annelida and molluscs are the best represented, numerically as well as...

Etude bibliographique de quelques espèces planctoniques et benthiques littorales de la Manche - Volume 1 - Espèces phytoplanctoniques ArchiMer
Erard-le Denn, Evelyne; Populus, Jacques.
This catalogue deals mainly with common phytoplanktonic species found in the Channel. It is part of a bibliographical survey on pelagos and benthos. The main idea was to gather the largest possible amount of data on the eco-physiology of each species. To do so, studies were conducted in the main marine region where the species had been found and analysed. We focused on several reference ecological studies conducted in the coastal Channel, on the E.D.F. sites, by the C.N.E.X.O., the I.S.T.P.M. and some university laboratories. A great attention was also paid to the studies on seasonal cycles carried out in laboratories in Plymouth, Helgoland and in the Irish zones. (unverified OCR)

Le merlu du golfe de Gascogne et de la mer Celtique : Croissance, Répartition spatiale et bathymétrique, Ecologie alimentaire et Assemblages ArchiMer
Kacher, Mohamed.
In the Bay of Biscay and Celtic Sea waters, hake is considered as genetically homogeneous and form a unique stock with identical meristic characteristics. The vertebral mean vary from 50,68 (vertebrae) during the first year of life to 51,11 (vertebrae) for adults. 0-group Merluccius display a rapid growth with significant interannual variability (0.71 mm.day-1 in 2001 versus 0.74 mm.day-1 in 2002). The spawning period occurs in April and the average length on the firth January following the hatching is of 17.3 cm (first seasonal check / increment on the sagittal otolith is located about 0.143 cm from the nucleus). At the end of the first year of life the average length is about 24 cm. The longevity of the species is important and growth parameters (L =...

Arzul, G; Panouse, M; Romana, A; Fiala, M; Razouls, S; De Bovee, F; Labat, J.p..
As part of its nuclear program, E.D.F. put the C.N.E.X.O. in charge of the ecological study of a list of sites that had been considered for the implantation of nuclear power plants on the Mediterranean coast: PORT-la-N0UVELLE South, PORT-la-NOUVELLE North and FLEURY-sur-AUDE. The aim of this study is to compare, from an ecological point of view, the different sites during critical periods of the annual cycle: summer and spring. This report summarises the results of the two campaigns (ECOLION l and II) conducted on the area located between the Cap d'Agde and the Cap Leucate, and including the three studied sites. The study analysed the physicochemical parameters and the primary and secondary pelagic productions, and includes a qualitative and quantitative...

Les fonds ostréicoles de la Seudre et du Bélon ArchiMer
Hinard, Gustave.
Le développement plus ou moins rapide de l'huître, sur un banc naturel ou dans un parc,dépend en premier lieu de la nourriture qui lui est fournie. Or, celte nourriture est très variable, en qualité comme en quantité. suivant les lieux. de telle sorte que certains endroits du littoral sont impropres à l'ostréiculture, d'autres spécialement propres à l'élevage, ou à la pousse, ou à l'engraissement. Il est de règle qu'une huître s'engraisse mal dans les emplacements ou elle fut élevée; inversement, les centres d'engraissement les plus réputés conviennent peu, en général, à la reproduction et au demi-élevage. L'étude des divers facteurs qui peuvent agir sur la nutrition de l'huître, en particulier de ceux qui conditionnent les apports alimentaires, cette...

The Percy Sladen Trust expedition to the Indian ocean in 1905 - Vol. 4 ArchiMer
Gardiner, Stanley J..
This paper contains a description of the Lepidoptera, exclusive of the Tortricidae, Tineidae, Orneodidae, and Pterophoridae, of t he Seychelles Archipelago, and of the coral islands of Aldabra, Assumption, Cosmoledo and Astove, though the collections from the three latter islands are too small to be considered representative. The collections from the Seychelles were obtained very largely by Mr Hugh Scott, who spent eight months (July 1905-March 1909) in the group and devoted the whole time to entomological collecting.

Gruvel, M.; Joubin, L.; Vayssiere, A.; Perrier, R..
C'est à l'époque même (1883) où se terminait la Campagne du "Talisman", après celle du « Travailleur », que paraissait le grand travail du Dr Hoek sur les Cirrhipèdes recueillis dans l'Expédition du « Challenger ». Ce travail fut une véritable révélation en ce qui concerne ce groupe spécial, car cinquante-neuf espèces nouvelles s'y trouvaient décrites, dont un genre nouveau, fort intéressant. [OCR NON CONTRÔLE]

Observatoire national du cycle de vie de l’huître creuse en France. Rapport annuel ECOSCOPA 2017 ArchiMer
Pouvreau, Stephane; Fleury, Elodie; Petton, Sebastien; Corporeau, Charlotte; Lapegue, Sylvie.
Occupant une place de premier ordre dans les paysages côtiers français, l’ostréiculture est le premier contributeur de la filière aquacole française avec une production estimée à 85 000 tonnes ces dernières années. Véritable espèce ingénieur, l’huître creuse, installée en France depuis plus de 50 ans, joue aussi un rôle essentiel sur le plan écologique dans les écosystèmes qui l’abritent. Pourtant, depuis plusieurs années, cette filière subie une baisse de production et les bancs naturels, garants de la diversité génétique, sont mis en danger. Ces phénomènes sont la conséquence directe de l’épizootie causée par OsHV-1 (sous sa forme µVar) affectant les naissains et des mortalités d’adultes associées à la bactérie Vibrio aestuarianus. Ces épisodes de...

The Percy Sladen Trust expedition to the Indian ocean in 1905 - Vol. 2 ArchiMer
Gardiner, Stanley J..
In the following pages sorne account is given of 20 species of Nemerteans from the Eastern Indian Ocean. In addition to those collected by the Percy Sladen Expedition, we bave been able to examine a collection made by Mr. Oyril Crossland at and near Zanzibar, and also a few procured by Professor Herdman from Ceylon. To these two gentlemen we desire to express our thanks. Other specimens reached us besides those described below, but owing to their imperfect condition or to their unsatisfactory preservation we have not included them in our account. [NOT CONTROLLED OCR]

La nouvelle stratégie mise en place au cours de la 9ème période de surveillance de Gravelines consiste à abandonner l'étude temporelle caractérisée par un grand nombre de campagnes pour privilégier les variations spatiales, pour trois situations annuelles printanière, estivale et automnale, afin de comparer l'ensemble des paramètres aux quatre stations entrée de centrale, rejet, point impacté à T = + 3°C et point de référence T = O°C (hors impact). Les domaines d'études sont: la climatologie, le fonctionnement de la centrale, l'hydrologie, la microbiologie, le plancton, l'halieutique, le benthos. Dans tous les domaines l'effort est mis sur les estimations de déficit de biomasses au rejet d'une part et les compétitions intréspécifiques quand le milieu...

Roule, L.; Marion, A.f.; Billard, A.; Koehler, R.; Fischer, H.; Joubin, L.; Calvet, L..
Les Annélides et les Géphyriens , recueillis dans les dragages du "Travailleur" et du "Talisman", cumprennent 21 espèces. Ce nombre n'est pas très considérable . Il faut tenir compte, en effet , de la petitesse des individus, qui les laisse passer aisément inaperçus. Pourtant, par l'importance des caractères , par la haute valeur de certaines particularités, en plusieurs cas par la grande quantité des échantillons recueillis , cette collection supplée à un tel défaut. Son étude permet d'acquérir, sur les deux classes , quelques notions d'ensemble au sujet de leur manière d'être dans les grands fonds de la mer. [OCR NON CONTRÔLE]

Verspreiding en ecologie van de dansmug Glyptotendipes ospeli in Nederland (Diptera: Chironomidae) Naturalis
Tempelman, D..
Distribution and ecology of the chironomid Glyptotendipes ospeli in the Netherlands (Diptera: Chironomidae) This paper adresses the ecology, biology and distribution of the larvae of the chironomid Glyptotendipes ospeli Contreras-Lichtenberg, 1999. No information is available on the ecology and biology of the adults. Glyptotendipes ospeli was described in 1999 after larvae collected in Amsterdam (the Netherlands) had been reared to adults. There is only one record from outside the Netherlands: a larva collected in Pripyat River (Belarus). In the Netherlands, larvae of this species have so far been recorded on 36 localities. Locally it can be rather common. Most records originate from standing, medium-sized, shallow waters in cities, e.g. ponds in city...

De boorvlieg Myopites apicatus nieuw voor Nederland (Diptera: Tephritidae) Naturalis
Smit, J.T..
Myopites apicates, a new fruitfly for the Netherlands (Diptera: Tephritidae) For some time a representative of the genus Myopites was expected to be found in the Netherlands, as three species were known to occur in the surrounding countries (M. tenellus, M. eximia, M. innulaedyssentericae). In 2003 Myopites apicatus Freidberg, 1980 was finally recorded. Surprisingly, this was not one of the aforementioned three species. In this paper a key to the four species known from northwestern Europe is presented.

Het zweefvliegengenus Sphegina in Nederland (Diptera: Syrphidae) Naturalis
Smit, J.T..
The genus Sphegina Meigen, 1822 in the Netherlands (Diptera: Syrphidae) A survey of the genus Sphegina in the Netherlands is given. Some nomenclatural changes are indicated, which resulted in the following five species which are now known from the Netherlands: Sphegina clavata (Scopoli, 1763), Sphegina clunipes (Fallén, 1817), Sphegina elegans (Schummel, 1843), Sphegina sibirica Stackelberg, 1953 and Sphegina verecunda Collin, 1937. Some of the rarer species were confused with other species in the past or overlooked in the field. Several collections were re-examined and new records were gathered. This resulted in new distribution maps for the Dutch species and a description of the habitats.

Carpelimus zealandicus, een nieuwe kortschildkever voor Nederland (Coleoptera: Staphylinidae) Naturalis
Cuppen, J.G.M..
Carpelimus zealandicus, a new rove beetle for the Netherlands (Coleoptera: Staphylinidae) In this paper the first occurrence in the Netherlands of the rove beetle Carpelimus zealandicus, originating from New Zealand, is reported. One specimen was collected on 23.v.2002 on the banks of the straightened lowland stream Hoge Raam near Sint Hubert (province of Noord- Brabant). In Europe, banks of different types of water form the normal habitat of C. zealandicus, with an apparent preference for newly created ones. During a period of forty years after the introduction of the species in Europe (England) and by an apparently good colonisation power, C. zealandicus has succeeded to build up a large distribution area in Western Europe. Despite occasionally large...
