| The diversity of the V3 loop tip motif sequences of HIV-1 subtype B was analyzed in patients from Botucatu (Brazil) and Montpellier (France). Overall, 37 tetrameric tip motifs were identified, 28 and 17 of them being recognized in Brazilian and French patients, respectively. The GPGR (P) motif was predominant in French but not in Brazilian patients (53.5% vs 31.0%), whereas the GWGR (W) motif was frequent in Brazilian patients (23.0%) and absent in French patients. Three tip motif groups were considered: P, W, and non-P non-W groups. The distribution of HIV-1 isolates into the three groups was significantly different between isolates from Botucatu and from Montpellier (P < 0.001). A higher proportion of CXCR4-using HIV-1 (X4 variants) was observed in... |

| Although the broad concept of mental models is gaining currency as a way to explore the link between how people think and interact with their world, this concept is limited by a theoretical and practical understanding of how it can be applied in the study of human-environment relationships. Tools and processes are needed to be able to elicit and analyze mental models. Because mental models are not directly observable, it is also important to understand how the application of any tools and processes affects what is measured. Equally important are the needs to be clear on the intent of the elicitation and to design the methods and choose the settings accordingly. Through this special edition, we explore how mental models are elicited using two approaches... |

| The fish remains sampled from archaeological sites are generally the result of human food refuse; therefore, the study of retrieved fish scales may provide reliable information on the season of capture and on paleoclimate and paleoenvironmental changes. Among Western European freshwater fishes, the grayling, Thymallus thymallus¸ has the most easily recognizable scales and is a commonly recovered species from Paleolithic contexts. This study, therefore, is based on the growth pattern analysis of modern and archaeological scales from grayling specimens. The modern specimens were collected monthly in France (n = 22), Switzerland (n = 16), Finland (n = 20) and Sweden (n = 10). Scale growth patterns were measured using numerical analysis to a high accuracy. The... |

| 15% of the shellfish production in France comes from natural deposits and the other 85% from farming. Years 1980-1990 showed a slight decrease in the shellfish production then a resurgence from 1985 onwards, an increase in the oyster production and a strong decrease in mussel production at the beginning of the 1980's followed by a resurgence due to the increase of open sea activity. In France, the shellfish market represents 300,000 tons, divided between oysters (40%), mussels (30%) and scallops (15%). Importations of mussels and scallops in order to supply the domestic market are important. On the other hand, external trade flows are very low as far as oysters are concerned: France is the only important market for oysters in Europe. (unverified OCR) |

| On December 11, 1999, Erika, an oil tanker flying the Maltese flag and loaded with 31 000 t of heavy fuel oil, was making its way from Dunkirk to Livorno when it encountered difficult weather conditions Southwest of the Brittany coast gale force winds 8 to 9 and 6 mwaves). On the morning of 12th December, the captain broadcast an SOS; his vessel was breaking in two, approximately 30 nautical miles to south of Penmarc'h Point (Fig. 1; Finistère, France). The fore section of the vessel sank during the night of the 12-13 December and the aft section was taken in tow on the morning December 13, but subsequently sank in the early afternoon. Both parts lay in 120 m of water and were located 10 km apart. Approximately, 19 000 t of heavy fuel oil were spilled into... |

| This study contributes to inventory programme on emerging pollutants in French waters and to the general reflection which will enable to update the list of relevant substnaces to be included in the new monitoring programmes to come. This work concerns the coastal part of the inventory programme on marine waters and sediments of France and five overseas french departments (OFD). In this goal, passive sampling techniques and direct extraction techniques have been tested through the implementation of in situ systems integrators POCIS (Polar Organic Chemical Integrative Sampler) and the extraction by SBSE bars (Stir bar sorptive extraction) directly in the waters sampled. Finally, analyzes of sediment completed the acquisition of data. Arount 40 stations were... |

| Estimation of changes in the relative abundance of fish species in catches off Arcachon, on the shelf and in the Bassin d'Arcachon, from 1727 to the present day, shows that some previously dominant species are becoming scarce. Some are actually not caught now in the south of the Bay of Biscay. Among these are the large bottom-living elasmobranchs with low reproduction rates, such as Echinorhinus brucus, Squatina squatina, Raja batis, Raja brachyura, Dasyatis pastinaca, Myliobatis aquila, Galeorhinus galeus, Mustelus asterias, Raja clavata, ,.. and some actinopterygians, such as Trigla lyra, while catches of Eutrigla gurnardus are much reduced. Bottom trawling is principally responsible for these reductions but all fishing methods used there have... |

| Le ROCCH produit les données chimiques nécessaires à l'évaluation de la qualité chimique des eaux marines, et notamment la qualité des zones conchylicoles françaises. En 2020, un total de 110 échantillons de mollusques collectés et analysés (dont 40 points hors zones conchylicoles suivies) permet de dresser un bilan de la qualité des côtes métropolitaines. Un secteur présente une non – conformité avec le dépassement de la teneur admissible en plomb dans les moules de la baie de Daoulas (sud – est de la rade de Brest). Plusieurs secteurs atteignent ou dépassent 50 % de la concentration-seuil : le nord de la rade de Brest (HAP), le sud de la rade de Brest (plomb et cadmium), le pertuis charentais (cadmium), l’estuaire de la Gironde (cadmium), l’étang de... |

| In a document from the General Secretariat of the Merchant Navy (P. 3 - MJ - June 1976), it is written: The coast is a rare asset, limited in essence as it is not interchangeable. Moreover, it is coveted and used by numerous users, sometimes aggressive or very powerful, who often take up the areas that are the richest from a biological point of view. This reality is at the origin of a number of land occupancy issues, all the more when a rational or enhancive preliminary choice has not been made. It can also lead to damages or pollutions, the coastal area being more exposed as rivers carry all the effluents which flow into them from their source to the ocean". Witnessing this competition, it appears that marine cultures need to be considered as very... |

| European stakeholders engaged in combatting the eutrophication of the North Sea welcomed three Water Framework Directive innovations: a more holistic approach to quality, the binding nature of WFD objectives, and greater public participation. Twenty years later, however, there has been a disappointing amount of progress in the reduction of diffuse pollution. In the Seine River Basin, the amount of livestock rearing is low; yet the basin is subject to significant diffuse pollution due to agriculture. This paper reports our study of this case; we examine the literature on WFD implementation policy in order to identify the physical and social causes of this failure to reduce diffuse pollution. We show that the nitrates, phosphorus, and pesticides that affect... |

| Marine mercury (Hg) concentrations have been monitored in the French coastline for the last half a century using bivalves. The analyses presented in this study concerned 192 samples of bivalves (mussels: Mytilus edulis and Mytilus galloprovincialis and oysters: Crassostrea gigas and Isognomon alatus) from 77 sampling stations along the French coast and in the French Antilles sea. The goals of this study were to assess MeHg levels in various common bivalves from French coastline, and to identify possible geographic, taxonomic or temporal variations of concentrations. We show that the evolution of methylmercury (MeHg) concentrations covary with total mercury (HgT) concentrations. Moreover, in most of the study sites, HgT concentrations have not decreased... |

| La production d'huîtres creuses françaises est actuellement supérieure à 100 000 tonnes. Elle est assurée par la culture d'une seule espèce, Crassostrea gigas, élevée dans la plupart des centres ostréicoles. Cette espèce s'est avérée résistante aux différentes maladies qui ont affecté tout d'abord l'huître creuse, Crassostrea angulata (Viroses), puis l'huître plate Ostrea edulis (Marteilia refringens et Bonamia ostreae). Ainsi, malgré toutes les controverses que cette implantation a provoquées, le fait essentiel est que depuis 1970-1971, la profession ostréicole a pu rester active, grâce à la culture de C. gigas, et ce, malgré les nombreux problèmes auquels elle a du faire face. |

| According to the media the French fishing industry has been in permanent state of crisis for the last 40 years. This paper recounts the events surrounding three major episodes of crises (late 1970s, mid-1990s, and early 2000s), and the measures taken by governments to resolve them. Invariably, these involved the distribution of sizeable amounts of public aids, in different forms, to the fishing sector. The efficacy of the subsidy programmes is discussed with reference to the goals stated by their proponents, regarding trade balance, competitiveness, profitability, employment and safety. Overall, the massive aids granted to the sector (comparable with the gross value of landings, annually) have not achieved the stated objectives and, paradoxically, have... |
