Résumé : The increase in the number of marinas and the problems that they pose has prompted Ifremer to analyse the consequences of these structures on the coastal environment. This report reviews the impacts associated with the construction and the operation of marinas. Some simple measures are proposed to reduce the inconveniences and ensure the compatibility of pleasure boating with other traditional activities. Most of all, these measures seek to reconcile the existence of marinas with environmental protection. This report is intended, in particular, for spatial planners and those responsible for protecting the coastal environment: representatives of administrative bodies; national, local, county ("department") and regional governments; organisations and associations in charge of environmental conservation.
La multiplication des ports de plaisance et les problèmes qu'ils posent ont incité l'Ifremer à analyser les conséquences de ces constructions sur le milieu littoral. L'ouvrage présenté passe en revue les impacts liés à la construction et à l'exploitation du port. Il propose quelques mesures simples qui visent à réduire les nuisances et assurer la compatibilité de la plaisance avec les autres activités traditionnelles. Et, surtout, il cherche à concilier l'implantation du port avec la protection de l'environnement. Cet ouvrage s'adresse, en particulier, à toutes les personnes qui ont des responsabilités dans la protection et l'aménagement du littoral: représentants de l'État, de l'Administration, des municipalités, des départements, des régions, organismes et associations chargés de sa sauvegarde.

Résumé : International audience
Hepatic periportal fibrosis, which affects 5–10% of subjects infected by Schistosoma mansoni, is caused by the T cell-dependent granuloma that develop around schistosome eggs. Experimental models of infection have shown that granuloma and fibrosis are tightly regulated by cytokines. However, it is unknown why advanced periportal fibrosis occurs only in certain subjects. The goal of the present study was to evaluate the cytokine response of S. mansoni-infected subjects with advanced liver disease in an attempt to relate susceptibility to periportal fibrosis with an abnormal production of cytokines that regulate granuloma and fibrosis. Fibrosis was evaluated by ultrasound on 795 inhabitants of a Sudanese village in which S. mansoni is endemic: advanced periportal fibrosis was observed in 12% of the population; 35% of the affected subjects exhibited signs of portal hypertension. Age (odds ratio (OR), 11.5), gender (OR, 4.2), and infection levels (OR, 2.2) were significantly (p < 0.01) associated with hepatic fibrosis. Cytokines produced by egg-stimulated blood mononuclear cells from 99 subjects were measured (75 with no or mild fibrosis; 24 subjects with advanced fibrosis). Multivariate analysis of cytokine levels showed that high IFN-γ levels were associated with a marked reduction of the risk of fibrosis (p = ‫OR, 0.1); in contrast, high TNF-α levels were associated with an increased risk (p = 0.05; OR, 4.6) of periportal fibrosis. Moreover, infection levels were negatively associated with IFN-γ production. These results with observations in experimental models strongly suggest that IFN-γ plays a key role in the protection of S. mansoni-infected patients against periportal fibrosis, whereas TNF-α may aggravate the disease.

Résumé : International audience
Well-designed and effectively managed networks of marine reserves can be effective tools for both fisheries management and biodiversity conservation. Connectivity, the demographic linking of local populations through the dispersal of individuals as larvae, juveniles or adults, is a key ecological factor to consider in marine reserve design, since it has important implications for the persistence of metapopulations and their recovery from disturbance. For marine reserves to protect biodiversity and enhance populations of species in fished areas, they must be able to sustain focal species (particularly fishery species) within their boundaries, and be spaced such that they can function as mutually replenishing networks whilst providing recruitment subsidies to fished areas. Thus the configuration (size, spacing and location) of individual reserves within a network should be informed by larval dispersal and movement patterns of the species for which protection is required. In the past, empirical data regarding larval dispersal and movement patterns of adults and juveniles of many tropical marine species have been unavailable or inaccessible to practitioners responsible for marine reserve design. Recent empirical studies using new technologies have also provided fresh insights into movement patterns of many species and redefined our understanding of connectivity among populations through larval dispersal. Our review of movement patterns of 34 families (210 species) of coral reef fishes demonstrates that movement patterns (home ranges, ontogenetic shifts and spawning migrations) vary among and within species, and are influenced by a range of factors (e.g. size, sex, behaviour, density, habitat characteristics, season, tide and time of day). Some species move <0.1–0.5 km (e.g. damselfishes, butterflyfishes and angelfishes), <0.5–3 km (e.g. most parrotfishes, goatfishes and surgeonfishes) or 3–10 km (e.g. large parrotfishes and wrasses), while others move tens to hundreds (e.g. some groupers, emperors, snappers and jacks) or thousands of kilometres (e.g. some sharks and tuna). Larval dispersal distances tend to be <5–15 km, and self-recruitment is common. Synthesising this information allows us, for the first time, to provide species, specific advice on the size, spacing and location of marine reserves in tropical marine ecosystems to maximise benefits for conservation and fisheries management for a range of taxa. We recommend that: (i) marine reserves should be more than twice the size of the home range of focal species (in all directions), thus marine reserves of various sizes will be required depending on which species require protection, how far they move, and if other effective protection is in place outside reserves; (ii) reserve spacing should be <15 km, with smaller reserves spaced more closely; and (iii) marine reserves should include habitats that are critical to the life history of focal species (e.g. home ranges, nursery grounds, migration corridors and spawning aggregations), and be located to accommodate movement patterns among these. We also provide practical advice for practitioners on how to use this information to design, evaluate and monitor the effectiveness of marine reserve networks within broader ecological, socioeconomic and management contexts.

Résumé : International audience
Chelonanthus alatus is a bat-pollinated, pioneer Gentianaceae that clusters in patches where still-standing, dried-out stems are interspersed among live individuals. Flowers bear circum-floral nectaries (CFNs) that are attractive to ants, and seed dispersal is both barochorous and anemochorous. Although, in this study, live individuals never sheltered ant colonies, dried-out hollow stems--that can remain standing for 2 years--did. Workers from species nesting in dried-out stems as well as from ground-nesting species exploited the CFNs of live C. alatus individuals in the same patches during the daytime, but were absent at night (when bat pollination occurs) on 60.5% of the plants. By visiting the CFNs, the ants indirectly protect the flowers--but not the plant foliage--from herbivorous insects. We show that this protection is provided mostly by species nesting in dried-out stems, predominantly Pseudomyrmex gracilis. That dried-out stems remain standing for years and are regularly replaced results in an opportunistic, but stable association where colonies are sheltered by one generation of dead C. alatus while the live individuals nearby, belonging to the next generation, provide them with nectar; in turn, the ants protect their flowers from herbivores. We suggest that the investment in wood by C. alatus individuals permitting still-standing, dried-out stems to shelter ant colonies constitutes an extended phenotype because foraging workers protect the flowers of live individuals in the same patch. Also, through this process these dried-out stems indirectly favor the reproduction (and so the fitness) of the next generation including both their own offspring and that of their siblings, all adding up to a potential case of inclusive fitness in plants.

Résumé : International audience
Marine Protected Areas (MPAs) are increasingly used for biodiversity conservation and the management of sustainable fisheries. The use of taxonomic surrogates in routine monitoring of the reserve effects on fish assemblages may represent a promising method due to its substantial technical and economic benefits. However, higher taxonomic ranks should be used as surrogates with caution, especially for fish, where the approach is still virtually undocumented. This study aims to shed light on relationships between taxonomic relatedness and ecological similarity, which is crucial to assess the relevance of species surrogacy to reflect species-level information and detect changes in fish related to protection regimes. By analyzing data from a Mediterranean MPA, we show that rather being related to taxonomic relationships, the ability of higher taxa to reflect species-level patterns was explained in terms of aggregation level and distribution of species within taxa. Null models using random aggregations of species were created to identify the best surrogates able to depict changes in responses of assemblages to protection observed at the species-level. Comparison of null model predictions with the more classical higher-taxon approach revealed that the latter was not reliable because, unlike null model outcomes, surrogates determined empirically were not relevant for other subsequent independent monitoring. The effectiveness of species surrogates to depict changes in responses of assemblages to protection observed at the species-level depended (1) on the numerical resolution of the aggregation and (2) the magnitude of differences between protected and unprotected locations. Such findings suggest that surrogacy approaches may be applied for routine monitoring of Mediterranean reef fish communities, although mere empirical determinations of sufficient taxonomy seems to be not reliable, legitimizing the use of alternative methods based on null models. Guidelines for the careful use of species surrogacy in the ecological evaluation of MPAs on fish assemblages are provided.

Résumé : Shelled molluscs are comprised of bivalves and gastropods. They are settled mainly on the continental shelf as benthic and sedentary animals due to their heavy protective shell. They can stand a wide range of environmental conditions. They are found in the whole trophic chain and are particle feeders, herbivorous, carnivorous, and predators. Exploited mollusc species are numerous. The main groups of gastropods are the whelks, conchs, abalones, tops, and turbans; and those of bivalve species are oysters, mussels, scallops, and clams. They are mainly used for food, but also for ornamental purposes, in shellcraft industries and jewelery. Consumed species are produced by fisheries and aquaculture, the latter representing 75% of the total 11.4 millions metric tons landed worldwide in 1996. Aquaculture, which mainly concerns bivalves (oysters, scallops, and mussels) relies on the simple techniques of producing juveniles, natural spat collection, and hatchery, and the fact that many species are planktivores.

Résumé : La mise en œuvre des politiques publiques du patrimoine et, plus largement, de l’environnement, se réalise par des instruments normatifs qui traduisent leur appréhension et leur saisie par le droit. Les différents outils institutionnels, conventionnels, législatifs et réglementaires contribuent dans une large mesure à la protection du patrimoine et de la biodiversité, au même titre que ceux qui se situent dans les domaines politique, économique et social. La protection concerne aussi bien le patrimoine naturel et la biodiversité que le patrimoine culturel et immatériel. La nature et le contenu des dispositifs de protection, qu’elle soit mise en œuvre aux niveaux national, régional ou international, procèdent de paramètres et se réfèrent à des objectifs divers mais convergents, parmi lesquelles les problématiques identitaire et patrimoniale occupent une place souvent déterminante. Elle doit en outre prendre en compte la spécificité des milieux comme des sociétés, et la relation des populations et des communautés à leur patrimoine, aussi bien reçu que construit.
The implementation of heritage public policies and, more widely, environmental policies, are carried out through legal instruments, which reveal the impact of the law on them. These different institutional, legislative and regulatory tools deeply contribute to the protection of heritage and biodiversity, as they do in the political, economical and social fields. The protec-tion they offer concerns as well natural, cultural and intangible heritage. The nature and methods of the protection, at the national, regional or international levels, result from para-meters and refer to different but convergent objectives, among which identity and heritage dimensions often have a decisive place. Moreover this protection must consider the specific environmental and social backgrounds, and the relation of the populations and communities with their heritage, let it have been received or built.

Résumé : This study assesses the place of MSEs in Haiti and gives a brief description of the relevant economic, regulatory and technological instruments of economic development and environmental protection. The discussions suggest that the application of such instruments will encourage and improve economic development in Haiti. The infrastructure necessary for MSEs drives growth and offers added value to economic development in Haiti. With an overview of Haitian MSEs we have been able to identify and palliate insufficiencies in the legislative framework regulating the operation of MSEs, as well as, understand their involvement in economic growth. MSEs are a powerful tool to reduce poverty, facilitate economic development and reinforce policies supporting environmental protection.
Ce travail dresse un bilan sur la situation des TPE en Haïti et propose une analyse succincte de l’impact des instruments économiques, règlementaires et technologique au développement économique et à la protection de l’environnement. Les discussions menées ont permis de découvrir que l’application de ces instruments est une perspective d’amélioration du développement économique des TPE.La structuration des TPE reste la principale action stratégique de croissance et représente une grande valeur ajoutée pour le développement économique du pays. Le panorama des TPE haïtiennes nous a permis de compléter les insuffisances du cadre légal réglementant le fonctionnement des TPE et de comprendre leur participation à la croissance économique du pays. Ce sont des outils indispensables pour réduire la pauvreté, faciliter le développement économique et renforcer les politiques de protection de l’environnement à travers le pays.

Résumé : International audience
1. The use of targets to provide measurable objectives and benchmarks for management, conservation, andrestoration of ecosystems is commonplace. In the marine and coastal realms, targets have been successful insetting sustainable limits to fisheries harvests, thresholds for pollutants, and recommended amounts ofrepresentative habitat included in marine protected area (MPA) networks. Quantifiable targets can dissuadegovernments from making dubious claims about investments in ocean protection that sound impressive butcannot be verified. Examples are presented where protection targets have been used successfully for marinemanagement, and instances where measurable and meaningful benchmarks serve to allow tracking of true progress.2. However, the setting of targets can also be a double-edged sword. In some cases, targets have proven useful,but in many instances, interventions made to fulfil targets not only give a false illusion of progress or even success,they present opportunity costs that impede further conservation.3. Some of these issues were raised in the 2003 article ‘Dangerous Targets?: Unresolved issues and ideologicalclashes around marine protected areas’ that appeared in Aquatic Conservation: Marine and FreshwaterEcosystems. Since its publication, the article’s warnings about how targets can sometimes be dangerous andcounter-productive have led to intense debate among scientists and policy-makers alike, and the paper has beencited in more than 500 publications. Yet today, more than a dozen years after the first ‘Dangerous Targets’publication, new targets are driving more MPA designations and conservation strategies than ever before, andthe ‘dangerous’ aspects of target setting have been largely ignored.4. This paper discusses old ‘dangers’ in the context of new developments in marine conservation, including thelingering problem of having simplistic metrics drive marine policies, and the unintended result that can often occurwhen outputs (percentage of area under MPA designation) do not align with true outcomes of effectivemanagement and conservation. Newly emerging ‘dangers’ in letting areal targets (percentage of area underMPA designation) drive MPA designations are also discussed, including how the rush to fulfil obligations toprotect a certain proportion of area is taking place in planning, separate from broader level, and potentiallymore holistic, marine spatial planning (MSP).5. The paper suggests five recommendations that would allow policy-makers to use targets more effectively,including: (1) increase transparency in planning, especially around specific goals and objectives of MPAestablishment; (2) use time-based areal targets when representativity is a goal of the protected area strategy; (3)

Résumé : Les espaces naturels protégés sont aujourd’hui à l‘échelle mondiale l’une des principales politiques publiques mises en œuvre pour faire face à la destruction des écosystèmes. Leur nombre a beaucoup augmenté ces dernières années et les modes d’action qu’ils recouvrent se sont considérablement diversifiés. Pour autant, les écosystèmes continuent à se dégrader, et l’efficacité de ces dispositifs est souvent remise en cause. Cette thèse vise à analyser les facteurs influant sur l’efficacité des espaces protégés pour la conservation d’écosystèmes amazoniens encore peu dégradés. Elle étudie pour cela la mise en œuvre de dispositifs relevant de doctrines de gestion de l’environnement différentes, basées sur (i) la limitation réglementaire maximale des activités humaines impactantes pour les écosystèmes, (ii) la gestion des ressources par des populations locales ou traditionnelles ou (iii) la mise en place d’une gestion forestière durable sur des terres publiques. Nous nous plaçons dans une posture comparative entre la Guyane (France) et l’Amapá (Brésil), territoires partageant une frontière commune, principalement matérialisée par le fleuve Oyapock. La comparaison internationale entre ces deux régions présentant une couverture exceptionnelle en espaces protégés, dans des conditions écologiques et géographiques relativement similaires, nous permet d’observer l’influence du contexte historique et sociopolitique sur les modes de prise en charge de la gestion de l’environnement par les aires protégées. Nous nous sommes basés sur une approche constructiviste, appuyée sur une production de données principalement qualitatives (entretiens semi-directifs, analyse de documents, observation participante…). Nous avons ainsi procédé à une déconstruction critique des dispositifs « aires protégées », permettant de mettre en lisibilité les enjeux environnementaux qu’ils portent, et d’analyser l’efficacité environnementale des stratégies mises en œuvre. Cette analyse s’est articulée autour d’une lecture à la fois diachronique et multiscalaire des processus de gestion.Nous montrons que la mise en place des espaces protégés de Guyane et d’Amapá a été portée par des coalitions d’acteurs structurées autour de doctrines de gestion, c’est à dire de conceptions partagées des conditions de mise en œuvre d’une « bonne gestion environnementale ». Les dispositifs créés ont hérité des ressources stratégiques d’action et de la légitimité de ces coalitions. Les coalitions porteuses de la création des espaces protégés en Amapá sont fortement articulées aux mouvements sociaux et environnementaux plus généraux de l’Amazonie brésilienne, notamment pour les revendications socio-environnementales émergeant à la sortie de la période dictatoriale. En Guyane française, les espaces naturels protégés sont principalement la résultante de compromis entre d’une part une volonté d’exemplarité de l’action de la France en Amazonie, et d’autre part une recherche de minimisation des conflits avec les acteurs politiques locaux.
Nowadays, natural protected areas are one of the main public policies implemented at the international level in order to prevent the destruction of ecosystems. During the last decades, they became very numerous, and mobilized more and more diversified modes of action. However, natural ecosystems continue to deteriorate, and the effectiveness of protected areas is often questioned. The aim of this thesis was to analyse the factors influencing the effectiveness of protected areas in a context of Amazonian ecosystems that are still well preserved. We observed the implementation of environmental management arrangement (protected areas) that are based on various doctrines: (i) the strong limitation of all harmful human activities through legislation; (ii) the management of resources by local or traditional populations; and (iii) the implementation of sustainable forest management on public lands. We adopted a comparative approach between Guyana (France) and Amapá (Brazil), territories that share a common border, mainly identifiable by the Oyapock River. These two territories present quite similar ecological and geographical conditions, and both have an exceptional coverage of protected areas. Therefore this international comparison allowed us to observe the influence of the historical and socio-political context on the implementation of protected areas. We used a constructivist approach, mainly based on qualitative data (semi-structured interviews, document analysis, participant observation...). We effected a critical deconstruction of "protected areas" management arrangements in order to make their environmental objectives intelligible, and we analysed the environmental effectiveness of the strategies implemented. This analysis was based on a diachronic and multiscalar lecture of management processes. We show that the establishment of protected areas in Guiana and Amapá was led by coalitions of actors structured around management doctrines, i.e. shared conceptions of "good environmental management". Management arrangements created inherited the strategic resources of action and the legitimacy of these coalitions. In Amapá, coalitions were strongly articulated with wider social and environmental movements of the Brazilian Amazon, especially in the case of socio-environmental claims rising at the end of the dictatorship. In French Guiana, the natural protected areas are mainly the result of compromise between the French willingness to serve as an example in the Amazon region, and the minimisation of conflicts with local politicians.

Résumé : International audience
The French West Indies (F.W.I.) were French colonies with a specific legal frame until 1946 when they became French departments. Since that time the legal frame in force concerning archaeological heritage protection is exactly the same than in metropolitan France. In this system all the laws relating to cultural heritage are grouped in the "Code du Patrimoine" (Heritage code), which contains several topics such as archives, museums, archaeology and historic monuments. Some articles refer to the Penal Code, the Code of Urban Development, the Environmental Code or the Mining Code. These laws are supplemented by various decrees that define the applying conditions for different areas: rescue archeology (decree 2004-490), INRAP , advisory bodies, the content of the field reports, penal provisions, etc ... The heritage laws have been created in 1917 (Historic Monuments) and 1941 (archaeology). The law on rescue archeology is in force only since 2001 and is an application of the European Convention of Malta (1992). However, the implementation of the regulation and of the institutions in charge of is application in the French West Indies is fairly recent. In this presentation after a general presentation of the archaeological heritage protection French system we will focus on the different aspects of is application in F.W.I.: difficulties linked to the application of a system suited for metropolitan France, the level of the French West Indian people implication in the archaeological heritage protection and the future perspectives.

Résumé : International audience
AimEcological connectivity is currently considered to be essential to enhance biodiversity conservation efforts and benefit adjacent areas. We evaluate the spatial structure of vulnerable marine benthic invertebrate populations based on connectivity to improve the placement of marine protected areas.LocationGulf of Lions, NW Mediterranean Sea.MethodsWe used a spatially explicit metapopulation model to explore how larval dispersal affects marine benthic invertebrate dynamics at local and regional scales. Minimum recruitment success (the proportion of larvae that settle in a site and survive between spawning and first reproduction, which is required to ensure species persistence) is proposed as a measure of vulnerability. Three contrasting simulations were constructed: closed versus connected populations, habitat loss versus recruitment failure disturbances and varying patterns of oceanographic connectivity. The rescue factor (the ratio of minimum recruitment success in connected and closed populations) quantified the decrease in vulnerability because of oceanographic connectivity.ResultsIn the Gulf of Lions, connectivity reduced population vulnerability by a rescue factor of 5.3. The minimum recruitment success for regional persistence decreased from 3% to 0.2% when species' life expectancies increased from 2 to 50 years. Connectivity enabled the spread of individuals over the entire region, but there were higher densities in sink sites, where low retention rates do not allow for local persistence (western tip of the gulf). Source sites, defined as those sites bringing metapopulation resistance to recruitment failure and stresses from habitat loss, were located in the centre of the gulf.Main conclusionsConnectivity drives the spatial structure of population density distribution and population vulnerability in the absence of any other structuring factor. In the Gulf of Lions, marine protected areas are located in population sinks; however; if protection measures were taken in the central part, populations would benefit throughout the region via the rescue effect.

Résumé : The coastal marine environment presents some specificity compared to other aquatic environments: it is both the receiving end of pollution on land and the most biologically rich marine area, where are developing many uses (fisheries and aquaculture, salt production, tourism, thalassotherapy). The coastal zone is therefore vulnerable to chronic chemical pollution and its protection requires research, monitoring and regulation. A dual strategy can be put into place: a preventive approach to avoid placing on the market of toxic substances to humans and the environment, and a retrospective approach based on public policies for the protection and restoration of degraded aquatic environments.
Le milieu marin côtier présente une certaine spécificité par rapport aux autresmilieux aquatiques : il est à la fois le milieu récepteur ultime des pollutions terrestres et la zone la plus riche biologiquement, et le milieu où se développent de nombreuses activités (pêche et cultures marines, saliculture, tourisme, thalassothérapie). La zone côtière littorale est par conséquent vulnérable aux pollutions chimiques chroniques et sa protection nécessite recherche, surveillance et réglementation. Une double stratégie peut être mise en place : une approche préventive pour éviter la mise sur le marché de substances toxiques pour l'Homme et l'environnement, et une approche rétrospective basée sur des politiques publiques pour la protection et la restauration des milieux aquatiques dégradés.

Résumé : Sea fish farms with production of more than 20 tons per year in France must obtain two operating licences: (i) one for Sea Farming (AECM), with the aim of ensuring that the granted site and use of the maritime public domain for exploitation will respect all restrictions of general interest; (ii) one for regulating Facilities Classified for the Protection of the Environment (ICPE). Although the first one requires a relatively simple licence request file, the second one demands a very complete file, which includes, beyond the notice of exploitation information, a complete impact study, as well as a hazards study and a health and safety notice. In this context, petitioners in Corsica (adjustment of status or new exploitation) are faced with the same difficulties, which highlighted the need for a methodological guide adapted to each region's specific situation, assembling in particular the necessary baseline data (legal, zootechnical, geographical, climatic, socio-economic, ecological...) as well as recognised methods for evaluating the potential effects of the farm on the environment. Development of this guide was supported by ADEC and supervised by a steering committee composed of representatives from the administrations concerned, fish farmers and scientific bodies. The significant aspects dealt with the effects of fish farming on Posidonie herbarium, a protected species very present in Corsica and with coordinating the two AECM and ICPE procedures. For each part of the ICPE file, the guide introduces the technical or scientific context and, depending upon the case, the state of the art, sources of available data, acquisition and methods of acquiring measurements and of assessing the potential effects, as well as practical editing recommendations. Finally, the guide is made complete by a model schedule of conditions designed to help petitioners to have a specialist research department incorporate all or part of the file. This guide primarily concerns first-time marine facilities for exploitation in Corsica, conceived of as in the open sea rather than in confined spaces. Nonetheless, any fish farmer or future fish farmer needing to process a request for an exploitation licence may find it useful.
Les piscicultures marines de plus de 20 t/an de production sont soumises en France à l'obtention de deux autorisations d'exploiter : (i) celle au titre des Cultures Marines (AECM), visant à s'assurer que le site concédé et l'usage du domaine public maritime pour l'exploitation permettent de respecter l'ensemble des contraintes d'intérêt général ; (ii) celle au titre de la réglementation des Installations Classées pour la Protection de l'Environnement (ICPE). Si la première nécessite un dossier de demande d'autorisation relativement simple, la seconde requiert un dossier très complet, qui comprend, outre une notice de renseignements sur l'exploitation, une étude d'impact complète, ainsi qu'une étude des dangers et une notice d'hygiène et de sécurité. Dans ce contexte, les demandeurs en Corse (régularisation ou exploitation nouvelle) sont confrontés aux mêmes difficultés, ce qui a mis en évidence le besoin d'un guide méthodologique adapté aux spécificités régionales, rassemblant en particulier les données de base nécessaires (juridiques, zootechniques, géographiques, climatiques, socio-économiques, écologiques...) ainsi que les méthodes reconnues de l'évaluation des effets potentiels de la ferme sur l'environnement. L'élaboration de ce guide a été soutenue par l'ADEC et suivie par un comité de pilotage composé de représentants des administrations concernées, des pisciculteurs et d'organismes scientifiques. Les aspects importants ont porté sur les effets de la pisciculture sur l'herbier de Posidonie, espèce protégée très présente en Corse et sur la coordination entre les deux procédures AECM et ICPE. Pour chaque partie du dossier ICPE, le guide présente le contexte technique ou scientifique et selon le cas, l'état de l'art, les sources de données disponibles, les méthodes d'acquisition des mesures et d'évaluation des effets potentiels, ainsi que des recommandations pratiques de rédaction. Enfin, le guide est complété par un cahier des charges type destiné à aider les demandeurs à confier à un bureau d'étude spécialisé la réalisation de tout ou partie de la constitution du dossier. Ce guide concerne prioritairement les installations marines de nouvelles exploitations en Corse, envisagées en mer ouverte plutôt que dans des espaces confinés. Néanmoins tout pisciculteur ou futur pisciculteur devant instruire une demande d'autorisation d'exploiter peut y trouver intérêt.

Résumé : International audience
Dudley et al. [9] commented on our paper [11], arguing that the current IUCN objective-based categorization ofprotected areas, which is also used in marine protected areas (MPAs), should not be abandoned and replaced bythe new regulation-based classification system [11]. Here we clarify that we do not advocate replacing thecurrent IUCN categories, but highlight the benefits of using both the objective-based IUCN categories and thenew regulation-based classification when applied to MPAs. With an increasing number of MPA types beingimplemented, most of them multiple-use areas zoned for various purposes, assessing ecological and socioeconomicbenefits is key for advancing conservation targets and policy objectives. Although the IUCN categoriescan be used both in terrestrial and marine systems, they were not designed to follow a gradient of impacts andthere is often a mismatch between stated objectives and implemented regulations. The new regulation-basedclassification system addresses these problems by linking impacts of activities in marine systems with MPA andzone classes in a simple and globally applicable way. Applying both the IUCN categories and the regulationbasedclasses will increase transparency when assessing marine conservation goals.

Résumé : The document, fifth edition of a collection which has started in 1997, presents a survey of marine-related activities in France. The commercial sector includes exploitation and extraction of marine resources, manufacturing industry, private services. In this new edition, a special effort is devoted to the analysis of maritime ports related industries. The non-commercial sector includes public services, among which the Navy, state services, education, safety, marine and coastal environment protection, marine sciences. Each activity of the commercial sector is described by key figures (turnover, value added, employment). The non-commercial sector includes data on running costs, in particular personnel costs. In addition to indicators, qualitative information is provided on the recent developments and future prospects of industries.
Le document, cinquième édition d'une série lancée en 1997, présente un panorama des activités liées à la mer en France. Le secteur marchand comprend l'exploitation et l'extraction des ressources marines, l'industrie manufacturière, les services privés. Dans cette nouvelle édition, un effort particulier est consacré à l'analyse de l'activité portuaire. Le secteur non marchand est constitué des services publics, dont la Marine nationale, les services de l'État, l'enseignement, la sécurité, la protection de l'environnement littoral et marin, la recherche scientifique. Chaque activité du secteur marchand est décrite par des chiffres-clés (chiffre d'affaires, valeur ajoutée, emploi). Sur le secteur non marchand sont fournies des données de coûts, dont les coûts de personnel. Tous ces indicateurs sont accompagnés d'informations qualitatives sur l'évolution récente et les perspectives des branches d'activité.

Résumé : International audience
Testes of most male mammals present the particularity of being externalized from the body and are consequently slightly cooler than core body temperature (4-8 degrees C below). Although, hypothermia of the testis is known to increase germ cells apoptosis, little is known about the underlying molecular mechanisms, including cold sensors, transduction pathways, and apoptosis triggers. In this study, using a functional knockout mouse model of the cold and menthol receptors, dubbed transient receptor potential melastatine 8 (TRPM8) channels, we found that TRPM8 initiated the cold-shock response by differentially modulating cold- and heat-shock proteins. Besides, apoptosis of germ cells increased in proportion to the cooling level in control mice but was independent of temperature in knockout mice. We also observed that the rate of germ cell death correlated positively with the reactive oxygen species level and negatively with the expression of the detoxifying enzymes. This result suggests that the TRPM8 sensor is a key determinant of germ cell fate under hypothermic stimulation.Borowiec, A.-S., Sion, B., Chalmel, F., Rolland, A.

Cold/menthol TRPM8 receptors initiate the cold-shock response and protect germ cells from cold-shock-induced oxidation.

Résumé : Le tourisme est souvent présenté comme l’un des instruments d’un développement durable, même s’il connaît une expansion difficilement maîtrisable, au détriment du patrimoine environnemental, insulaire et littoral en particulier, comme dans les DOM-TOM.Le tourisme a des impacts, culturels et sociaux notamment, sur l’environnement. Les ressources du patrimoine alimentent de leur côté la demande et l’offre touristiques. Un tourisme assis sur une gestion ad hoc des ressources du patrimoine constitue un facteur puissant de durabilité du développement local. La soumission de l’activité touristique aux exigences de protection, de conservation et de gestion reproductible de la biodiversité et du patrimoine naturel, dans les aires protégées de la Caraïbe française en particulier, génère des approches, des stratégies et des comportements nouveaux. La démarche écotouristique appelle une gestion participative et intégrée des ressources et des espaces, et constitue un défi pour les opérateurs du tourisme comme pour les acteurs de l’environnement, et une opportunité de « réappropriation » de leur milieu de vie par les populations locales. Il faut alors en clarifier le concept et les implications ; puis en analyser les objectifs et les enjeux dans une perspective de développement durable.
Tourism often appears as one a tool for a sustainable development, even if it is not easy to control, in the détriment of island and costal environment heritage, as in French overseas regions. Besides the cultural and social impacts of tourism upon environment, the heritage resources nuture the touristic request and offer. If based on an appropriate management of those resources, it may be a strong incentive for local sustainable development. The respect of protection, conservation and sustainable management of biodiversity and natural resources by tourism, especially in the overseas regions of French West Indies, produces new approaches, strategies and behaviours. The ecotourism approach, calling for a joint and integrated management of resources and areas, is a challenge for tour operators as for environment actors, and brings local population an opportunity to reappropriate their life environment. Its concept and implications must then be clarified, before analysing its aims and stakes regarding sustainable development
