Résumé : International audience
Mapping spatial distributions of disease occurrence can serve as a useful tool for identifying exposures of public health concern. Infant mortality is an important indicator of the health status of a population. Recent literature suggests that neighborhood deprivation status can modify the effect of air pollution on preterm delivery, a known risk factor for infant mortality. We investigated the effect of neighborhood social deprivation on the association between exposure to ambient air NO2 and infant mortality in the Lille and Lyon metropolitan areas, north and center of France, respectively, between 2002 and 2009. We conducted an ecological study using a neighborhood deprivation index estimated at the French census block from the 2006 census data. Infant mortality data were collected from local councils and geocoded using the address of residence. We generated maps using generalized additive models, smoothing on longitude and latitude while adjusting for covariates. We used permutation tests to examine the overall importance of location in the model and identify areas of increased and decreased risk. The average death rate was 4.2‰ and 4.6‰ live births for the Lille and Lyon metropolitan areas during the period. We found evidence of statistically significant precise clusters of elevated infant mortality for Lille and an east-west gradient of infant mortality risk for Lyon. Exposure to NO2 did not explain the spatial relationship. The Lille MA, socioeconomic deprivation index explained the spatial variation observed. These techniques provide evidence of clusters of significantly elevated infant mortality risk in relation with the neighborhood socioeconomic status. This method could be used for public policy management to determine priority areas for interventions. Moreover, taking into account the relationship between social and environmental exposure may help identify areas with cumulative inequalities.

Résumé : Implementation of ecosystem-based approaches to marine management points to several shared objectives between conservation and fishery management that require better knowledge of the life history of the exploited resources, elucidation of the information encoded in the calcified tissues (otoliths, scales, bones, shells, and corals) of marine and freshwater organisms, and support for knowledge-based, sustainable ocean management and use. Calcified tissues have been employed since the 19th century to gain knowledge of life traits, population structure, and environmental relationships of fish and molluscs. Breakthrough advances include the discovery by Pannella (1971) of the daily growth increments and the discovery by Radtke (1984) of otolith tracer approaches, resulting in an exponential growth of publications and four dedicated international symposia. IOS2014 will be the fifth in a series of independent symposia convened since 1993, to encourage the exchange of information and expertise, and promote the development of new techniques and applications for otolith-based analysis in ecology, management, and conservation. This international forum is the centre for the exchange of information on developments in the field. New techniques of analysis, statistical treatment, and indeed new areas of application are all presented in this forum. The IOS series started in Hilton Head (USA) in 1993, followed by IOS1998 in Bergen (Norway), IOS2004 Townsville (Australia), and the IOS2009 Symposium held in Monterey (USA). In general, attendance ranged between 250–350 participants. IOS2009 counted 268 registrants from 36 countries, despite the economic crisis.

Résumé : Tourism in marine and coastal areas is a complex phenomenon. Tourism in coastal areas brings along both positive and negative effects on the environment as a result of activities exerted upon such areas by proponents and tourists. While tourism development results in the modification of coastal environments, it can also flourish where such environments are left unmodified as the pristine nature of the environments attract visitors. Alternatively, in order for marine and coastal tourism to develop and continue to attract tourists, there is the need for an integrated approach that can be translated into a sustainable coastal tourism development. The aim of this paper therefore, is to postulate and develop a framework and guideline to be addressed by decision-makers for coastal areas. Frameworks for sustainable coastal tourism development and coastal zone management (CZM) are suggested taking into account the multifaceted nature of the coastal environment. Although Hong Kong epitomizes a successful tourism destination, alternative tourism is attractive as the diversity of habitats and life forms makes the Hong Kong coastal area unique. For the ecological richness to continue to provide avenues for alternative tourism, it is argued that such frameworks should be adaptable and implemented for a sustainable coastal tourism policy.
La gestion des processus touristique dans des secteurs marins et côtiers est complexe. Les pratiques touristiques et récréatives s’accompagnent d’effets positifs et négatifs sur l'environnement. Le développement de tourisme peut s’épanouir sur des environnements faiblement modifiés mais il n’est pas sans conséquence sur la modification des environnements côtiers. Une gestion intégrée s’impose pour intégrer les pratiques touristiques dans un processus de développement côtier soutenable. Le but de cet article est de proposer un cadre et une orientation pour la gestion intégrée des secteurs côtiers. Des cadres pour le développement côtier soutenable de tourisme et la gestion côtière de zone (CZM) sont suggérés en tenant compte de la nature diversifiée des environnements côtiers. Bien que Hong Kong constitue destination touristique réussie, le tourisme littoral, avec des approches alternatives, est aussi un aspect à promouvoir tant autour de la diversité des habitats et que des formes de vie qui rendent le littoral d’Hong Kong unique.

Résumé : International audience
Idiopathic pulmonary fibrosis (IPF) is the most frequent chronic idiopathic interstitial pneumonia in adults. The management of rare diseases in France has been organised by a national plan for rare diseases, which endorsed a network of expert centres for rare diseases throughout France. This article is an overview of the executive summary of the French guidelines for the management of IPF, an initiative that emanated from the French National Reference Centre and the Network of Regional Competence Centres for Rare Lung Diseases. This review aims at providing pulmonologists with a document that: 1) combines the current available evidence; 2) reviews practical modalities of diagnosis and management of IPF; and 3) is adapted to everyday medical practice. The French practical guidelines result from the combined efforts of a coordination committee, a writing committee and a multidisciplinary review panel, following recommendations from the Haute Autorité de Santé. All recommendations included in this article received at least 90% agreement by the reviewing panel. Herein, we summarise the main conclusions and practical recommendations of the French guidelines.

Résumé : International audience
This study proposes a new approach for improving resource quality management, monitoring and treatment plant management, whatever the environmental and climatic stressors. First trend analysis of water quality at a river basin scale, based on historical water quality data and multivariate exploitation (principal component analysis, PCA), led to a classification of the monitoring stations with regard to the main pressures (land use, urbanization and hydroclimatic impacts). This method was applied to the Vilaine's watershed, the largest river basin in Brittany, western France, and one which is under agricultural and urban pressure. A complementary research using a UV index was proposed for the evaluation of spatial and temporal variations of water quality. This approach may be considered as a useful and relevant tool to quickly assess the variation of water quality and the main explanatory factors. It also points out monitoring stations under specific stressors considered as outliers regarding UV parameters. Finally, PCA and UV index give complementary results. PCA allows factors influencing drinking water resource to be highlighted and the UV index allows global water quality under specific times and impacts to be reflected.

Résumé : French Polynesia started it's Fish Aggregating Device programme in June 1981 with the positioning of the first buoy offshore of the main island of Tahiti. Since then, 251 structures have been installed throughout the 5 archipelagoes of this French overseas territory. The shape and size of the devices have evolved 8 times over this period, however, a single model has not yet been adopted. Trials are currently underway using lighter structures similar to those found in the Indian Ocean. The anchoring lines have progressively been modified through better knowledge of material and product availability, as well as better understanding of environmental constraints. The programme is entirely financed by the territorial government and managed by the public sector. This ongoing technical assistance, aimed towards the local small-scale coastal fishery, is considered an important factor to maintaining this activity alive. Up until 1997, this economical support policy of outer island populations far from the metropolis central town, along with incidental fishing methods around FADs, have given mitigated results without nevertheless putting into cause this programme. The use of 'drifting handlines' retained at the surface by small indicator floats are one of the contributing factors to the degradation of the anchor lines. It is now commonly accepted that a new fishing strategy must be adopted so that professional coastal fishermen become more aware with regards to an expensive work tool due to local bathymetric conditions, so that fishing effort is increased through the development of better adapted fishing techniques, and finally so that community spirit rules over individualism.Original Abstract: Le programme d'ancrage de DCP en Polynesie francaise a vu le jour en juin 1981 avec l'implantation d'un premier dispositif au large des cotes de Tahiti. Depuis cette date, ce sont 251 structures qui ont ete installees dans les cinq archipels de ce pays d'outre-mer. La forme et la taille des bouees ont evolue huit fois sans etre definitivement arretees a un seul modele et des essais sur des structures legeres de type " Ocean Indien " sont en cours. Les lignes d'ancrage ont fait l'objet de modifications progressives en raison de meilleures connaissances des produits ainsi que des contraintes du milieu environnant. Ce programme est finance en totalite par le territoire de la Polynesie francaise et gere par le secteur public. Il s'adresse a la pecherie artisanale et cotiere qui considere depuis de nombreuses annees cette assistance technique comme un atout indispensable au maintien de son activite. La politique d'engagement de ce soutien economique jusqu'en 1997 aupres des populations d'iles et atolls tres eloignes de la capitale ainsi que l'incidence de la technique de peche la plus repandue autour des DCP ont abouti a des resultats mitiges sans pour autant remettre en cause ce programme. En effet, les lignes a main derivantes et retenues en surface par une petite bouee temoin sont un des principaux facteurs de degradation des lignes d'ancrage. Il est desormais reconnu par tous les intervenants qu'une nouvelle strategie doit etre deployee afin que les pecheurs cotiers professionnels soient mieux responsabilises face a un outil de travail onereux en raison de la bathymetrie environnante, pour que l'effort de peche soit accru par l'utilisation de techniques de peche mieux adaptees, et enfin que l'esprit communautaire prime sur l'individualisme.

Résumé : International audience
Introduction: Shark-based ecotourism is significantly developing around the world, often without appropriate management of risk. This activity involves a risk of accidental bites on divers that can be quite severe or even fatal. Objectives: To determine if ecotourism companies' liability can be engaged in the context of bites on scuba divers in presence of hand-feeding practices, supporting the legitimacy of financial compensation for the victims. Methods: We analyzed the development from the mid-eighties to 2010 of shark-based ecotourism through artificial provisioning practices in Moorea Island (French Polynesia) and more specifically the features and motivation of two bites on divers by Sicklefin Lemon sharks. Results: The specific practice of hand-feeding can be considered as a facilitating factor for accidental bites on divers, potentially involving the diving operator's responsibility. Conclusions: Our findings should support the technical work of experts that might be called in such cases.

Résumé : A major goal of natural resource managers is to foster and maximize environmentally responsible behavior among resource users. Interpretation is the process of conveying a message to someone to (a) enhance the awareness and appreciation that the person has with their surroundings, and to (b) encourage pro-environmental actions. It is one management tool that can be used to influence the actions or inactions of recreational visitors. Effective interpretation prompts the target audience to take action and provides opportunities for the audience to take action. An understanding of behavior and behavior change guides interpretive efforts so that they are effective in influencing behavior. This paper investigates the application of behavioral principles to test the most effective interpretive messages in influencing snorkeler behavior in Mombasa Marine Park. Key messages were incorporated into a training workshop for all the snorkel boat operators and associated crew enabling them to deliver an interpretation program to their clientele. Results indicate that the introduced interpretation program successfully influenced the behavior of snorkeling clients (i.e. led to more pro-environmental snorkel behavior), and increased visitor satisfaction (largely due to the transfer of information through the guide).
Un objectif majeur de gestionnaires des ressources naturelles est de favoriser et d’optimiser le comportement respectueux de l’environnement parmi les utilisateurs des ressources. L’interprétation est le processus de transmission d’un message à quelqu’un pour (a) accroître la sensibilisation et l’appréciation que la personne de son environnement, et pour (b) encourager les actions pro-environnementales. C’est un outil de gestion qui peut être utilisé pour influencer les actions ou inactions lors des visites de loisirs. Une interprétation efficace oriente les actions du public et lui ouvre des possibilités d’action. Une compréhension du comportement et du changement du comportement guide les efforts d’interprétation afin qu’ils soient plus efficaces dans l’influence du comportement. Cet article étudie l’application des principes comportementaux pour tester l’interprétation la plus efficiente des messages qui influencent le comportement des randonneurs palmés dans le parc marin de Mombasa. Des messages clés ont été incorporés dans un atelier de formation destiné aux exploitants de bateaux de plongée avec tuba et à leur équipage pour formuler un programme d’interprétation à leur clientèle. Les résultats indiquent que le programme d’interprétation mis en place a réussi à influencer le comportement des clients de plongée en apnée (à savoir conduit à un comportement de plongée plus pro-environnement) et à augmenter la satisfaction des visiteurs (en grande partie en raison du transfert de l’information par le guide.

Résumé : International audience
The international symposium on Urban Growth and Natural Hazards, in particular in Developing Countries was held in the Université Blaise-Pascal, Clermont-Ferrand (France) on December 2 and 3, 1994. This meeting brought together about 70 researchers, Ph. D. students, and professionals from France and 12 other countries, representing universities, research agencies, as well as government and private companies. The symposium aimed to gather specialists who are engaged and acting in programmes on hazard appraisal, risk prevention and urban management in the city environment. These people compared experiences acquired in two different fields: on the one hand urban growth and its consequences, and on the other hand, natural hazards and their effects, in particular in developing countries.From the 41 contributions given at the symposium, 4 papers were selected by the editorial board of this Bulletin de l'Association de Géographes Français for this special issue, which includes three chapters corresponding to the three sessions of the symposium: (1) Natural hazards and environmental factors : inventory, diagnostic and classification, (2) Vulnerability of urban society and environment : concepts, approaches, and classification, (3) Tools for urban risk prevention and risk management in case of crisis and catastrophes.
Ce numéro du Bulletin de l'Association de Géographes Français résume les résultats des tables rondes et de 41 contributions de chercheurs français et étrangers au colloque international «Croissance urbaine et risques naturels dans les pays en développement» qui s'est déroulé à l'Université Blaise-Pascal, Clermont-Ferrand, les 2 et 3 décembre 1994. L'objectif général du colloque était de rassembler les diverses compétences existant en France et à l'étranger dans le domaine de l'évaluation et de la gestion des risques naturels et de confronter les expériences acquises à l'interface entre les villes en croissance et le champ d'action des phénomènes naturels créateurs de risques. Le colloque a donc réuni des chercheurs, des doctorants et des praticiens de 12 pays, chargés de prévention, de gestion des risques naturels et de gestion urbaine, principalement dans les grandes villes des pays en développement (P.E.D.).Les contributions ont été regroupées, exposées et discutées lors du colloque sous forme de 3 thèmes : (1) Les phénomènes naturels créateurs de dommages (= menaces) : diagnostic, inventaire et typologie, (2) Les vulnérabilités des sociétés et des espaces urbanisés : concepts, typologie et modes d'analyse, (3) Les outils d'aide à la prévention et à la gestion du risque en milieu urbain. Certaines d'entre elles ont fait l'objet des quatre articles de ce Bulletin de l'Association de Géographes Français.

Résumé : Overexploitation of marine resources remains a problem worldwide. Many works advocate for the use of marine reserves as a central element of future stock management in a sustainable perspective. In the present paper, we address the influence of protected areas upon fisheries sustainability within an eco-systemic framework through a dynamic bio-economic model integrating a trophic web, catches and environmental uncertainties. The model is spatially implicit. The evaluation of the ecosystem is designed through the respect along time of constraints of both conservation and guaranteed captures. Using the mathematical concept of invariance kernel in a stochastic context, we define different MPA effects according to biodiversity catches or mixed points of view. Numerical simulations inspired from data of Abore coral reef reserve in New Caledonia illustrate the main concepts. In this case, it is pointed out how MPA conservation effect is not necessarily conflicting with MPA catches effect. it is shown that such a co-viability requires medium exploitation rate. Moreover, the climatic changes represented by rise in cyclonic events seem to reinforce these assertions. (C) 2007 Elsevier B.V. All rights reserved.

Résumé : International audience
Overfishing and habitat destruction due to local and global threats are undermining fisheries, biodiversity, and the long-term sustainability of tropical marine ecosystems worldwide, including in the Coral Triangle. Well-designed and effectively managed marine reserve networks can reduce local threats, and contribute to achieving multiple objectives regarding fisheries management, biodiversity conservation and adaptation to changes in climate and ocean chemistry. Previous studies provided advice regarding ecological guidelines for designing marine reserves to achieve one or two of these objectives. While there are many similarities in these guidelines, there are key differences that provide conflicting advice. Thus, there is a need to provide integrated guidelines for practitioners who wish to design marine reserves to achieve all three objectives simultaneously. Scientific advances regarding fish connectivity and recovery rates, and climate and ocean change vulnerability, also necessitate refining advice for marine reserve design. Here we review ecological considerations for marine reserve design, and provide guidelines to achieve all three objectives simultaneously regarding: habitat representation; risk spreading; protecting critical, special and unique areas; reserve size, spacing, location, and duration; protecting climate resilient areas; and minimizing and avoiding threats. In addition to applying ecological guidelines, reserves must be designed to address social and governance considerations, and be integrated within broader fisheries and coastal management regimes.

Résumé : International audience
The genus Nasutitermes is among the most abundant wood-feeding Termitidae and an extremely diverse and heterogeneous group in terms of its biogeography and morphology. Despite the major role of several Nasutitermes species as structural pests, the phylogenetic status of this genus is still unclear, along with a confused taxonomy and species identification remaining difficult. The first aim of this review was thus to gather and discuss studies concerning the taxonomic status of the genus Nasutitermes in order to clarify this crucial point. Then, our goal was to gain new insights into the management of N. corniger, considered to be the most economically detrimental pest of this genus in South America and a Nasutitermes model species, while filtering available information concerning its biology through the prism of termite control, as well as critically examine the existing methods. We indeed strongly believe that increasing our knowledge of this species’ biological strategies is the key to progress in the challenging question of their sustainable management.

Résumé : International audience
The island of Moorea in French Polynesia is representative of a relatively well preserved small tropical oceanic island but both its terrestrial and marine ecosystems are currently under strong anthropogenic pressures. The terrestrial ecosystems are facing an increasing urbanization, and the destruction and modification of their natural habitats by cultivation and forestry plantations, accidental or intentional fires, and particularly by the invasion of alien plant and animal species. Coastal areas and reef ecosystems are threatened by shoreline artificialization, sedimentation due to soil erosion, increasing uses of marine and lagoon resources and frequency of coral bleaching events. A significant erosion of terrestrial and marine biodiversity is observed on the island since the last decades. In the context of the Land Management Plan (PGA) and Marine Area Management Plan (PGEM) recently set up in the island by local authorities, scientific surveys and inventories were made in 2006 in order to assess the status of terrestrial biodiversity (vascular plants) and marine biodiversity (reef fishes) and compare areas with different anthropogenic pressures. Studies conducted on the flora and the vegetation at low and middle elevation along altitudinal transects show that the plant invasion process is related to climatic and topographic factors, and species autoecology. The marine study aims to compare the protected areas with control areas in order to test the effectiveness of protection measures and to propose a streamlined monitoring protocol. A methodological study in both terrestrial and marine ecosystems was conducted in order to propose biodiversity indicators which are crucial for decision making in conservation and sustainable development of island biodiversity. We used Geographic Information System (GIS) as a fast and intuitive tool for mapping indicators and their variability. This methodological approach developed on the island of Moorea could be used as a model for other tropical islands
Moorea est une petite île océanique tropicale de la Polynésie française relativement bien préservée, mais dont les écosystèmes terrestres et marins sont actuellement soumis à de fortes pressions anthropiques. Le milieu terrestre est confronté à une urbanisation croissante, à la destruction ou à la modification des habitats naturels pour l’extension des cultures ou des plantations forestières, aux incendies volontaires ou accidentels, et particulièrement à l’invasion d’espèces végétales et animales introduites. Les zones côtières et les récifs coralliens sont menacés par de multiples perturbations telles que l’artificialisation des lignes de rivage, l’apport de sédiments dus à l’érosion des sols, l’augmentation des usages des ressources marines et lagonaires et de la fréquence des phénomènes de blanchissement du corail. Une érosion sensible de la biodiversité terrestre et marine de l’île est observée depuis les dernières décennies. Dans le cadre du Plan Général d’Aménagement (PGA) et du Plan de Gestion de l’Espace Maritime (PGEM) mis en place par les autorités locales, des inventaires scientifiques ont été réalisés en 2006 dans le but d’évaluer l’état de la biodiversité terrestre (plantes vasculaires) et marine (poissons récifaux) et de comparer des zones soumises à différentes perturbations. Les études réalisées sur la flore et la végétation de basse et moyenne altitude le long de transects altitudinaux montrent des processus d’invasion végétale différents en relation avec les facteurs climatiques, topographiques et autoécologiques des espèces. Les études en milieu marin visent à comparer des aires protégées à des aires témoins afin de suivre l’efficacité des mesures de gestion. La réflexion méthodologique menée parallèlement sur les deux écosystèmes a pour but d’illustrer différents indices de biodiversité nécessaires à la prise de décision en matière de conservation ou de développement durable de la biodiversité insulaire et de réaliser un état de référence pour établir un diagnostic sur l’état de la biodiversité. La représentation cartographique des indices à l’aide d’un SIG, illustrée dans cette étude avec la richesse spécifique terrestre et marine, permet une lecture intuitive et rapide de la variabilité de cet indice dont la restitution est basée sur une standardisation du nombre d’espèces. Cette approche méthodologique développée sur l’île de Moorea pourrait servir de modèle pour d’autres îles tropicales

Résumé : Society's needs for a network of in situ ocean observing systems cross many areas of earth and marine science. Here we review the science themes that benefit from data supplied from ocean observatories. Understanding from existing studies is fragmented to the extent that it lacks the coherent long-term monitoring needed to address questions at the scales essential to understand climate change and improve geo-hazard early warning. Data sets from the deep sea are particularly rare with long-term data available from only a few locations worldwide. These science areas have impacts on societal health and well-being and our awareness of ocean function in a shifting climate. Substantial efforts are underway to realise a network of open-ocean observatories around European Seas that will operate over multiple decades. Some systems are already collecting high-resolution data from surface, water column, seafloor, and sub-seafloor sensors linked to shore by satellite or cable connection in real or near-real time, along with samples and other data collected in a delayed mode. We expect that such observatories will contribute to answering major ocean science questions including: How can monitoring of factors such as seismic activity, pore fluid chemistry and pressure, and gas hydrate stability improve seismic, slope failure, and tsunami warning? What aspects of physical oceanography, biogeochemical cycling, and ecosystems will be most sensitive to climatic and anthropogenic change? What are natural versus anthropogenic changes? Most fundamentally, how are marine processes that occur at differing scales related? The development of ocean observatories provides a substantial opportunity for ocean science to evolve in Europe. Here we also describe some basic attributes of network design. Observatory networks provide the means to coordinate and integrate the collection of standardised data capable of bridging measurement scales across a dispersed area in European Seas adding needed certainty to estimates of future oceanic conditions. Observatory data can be analysed along with other data such as those from satellites, drifting floats, autonomous underwater vehicles, model analysis, and the known distribution and abundances of marine fauna in order to address some of the questions posed above. Standardised methods for information management are also becoming established to ensure better accessibility and traceability of these data sets and ultimately to increase their use for societal benefit. The connection of ocean observatory effort into larger frameworks including the Global Earth Observation System of Systems (GEOSS) and the Global Monitoring of Environment and Security (GMES) is integral to its success. It is in a greater integrated framework that the full potential of the component systems will be realised. Crown Copyright (C) 2011 Published by Elsevier Ltd. All rights reserved.

Résumé : Après avoir rappelé que comme concept de gestion des territoires, le développement durable peut s’inscrire dans un système territorial complexe, l’article s’interroge sur les imaginaires associés à la ruralité et à l’insularité. Largement issue du regard de nos sociétés urbaines, la critique des abus d’un modèle de développement insulaire peu respectueux d’un environnement détérioré et/ou à l’abandon, conduit à promouvoir une gestion des territoires intégrant également une dimension économique et socioculturelle, notamment un fort mouvement de « patrimonialisation », sorte de réinvention de l’île mythique, symbole d’un équilibre passé. Divers exemples (île grecque de Skopelos, Corse, Martinique) montrent que ressources et savoir-faire spécifiques, difficilement transposables en dehors du contexte insulaire, peuvent être considérés comme un atout pour le développement ; ils renforcent l’identité d’une communauté et inspirent des dynamiques sociales renouvelées. Pour autant, il importe de réfléchir aux interactions entre des filières qui partagent les mêmes lieux, les mêmes ressources et impliquent les mêmes personnes. À l’évidence, la qualité du lien social augmente la résilience du système territorial même si cela passe par une redéfinition des règles collectives qui visent à inventer des solidarités durables passant davantage par des savoir-être ensemble que par des savoir-faire purement techniques.
As a concept of territorial management, sustainable development can be analysed in the systemic vision allowed by complex territorial systems. This article wonders about the representations associated to rural areas and insularity. Largely encouraged by our modern societies, the critical vision of island development – not environmentally friendly models – promotes an integrated vision of development aiming at combining economical and sociocultural considerations. The great movement of cultural heritage, sort of reinvention of mythic islands symbolising a past equilibrium is then progressively supported. Different examples dealt with in this article (The Greek island of Skopelos, Corsica, Martinique) show that resources and specific know-how, not easily transferable out of the insular context, can be considered as strong advantages for development. They reinforce communities’ identity and favour new social dynamics. Obviously, quality ties increase the resilience of the territorial system even though it necessitates to redefine collective rules that aim at inventing sustainable solidarity relying mainly on knowing how to behave instead of pure technical know-how.

Résumé : Evidence has accumulated that climate variability influences the state and functioning of marine ecosystems. At the same time increasing pressure from exploitation and other human activities has been shown to impact exploited and non-exploited species and potentially modify ecosystem structure. There has been a tendency among marine scientists to pose the question as a dichotomy, i.e., whether (1) "natural" climate variability or (2) fishery exploitation bears the primary responsibility for population declines in fish populations and the associated ecosystem changes. However, effects of both climate and exploitation are probably substantially involved in most cases. More importantly, climate and exploitation interact in their effects, such that climate may cause failure in a fishery management scheme but that fishery exploitation may also disrupt the ability of a resource population to withstand, or adjust to, climate changes. Here, we review how exploitation, by altering the structure of populations and ecosystems, can modify their ability to respond to climate. The demographic effects of fishing (removal of large-old individuals) can have substantial consequences on the capacity of populations to buffer climate variability through various pathways (direct demographic effects, effects on migration, parental effects). In a similar way, selection of population sub-units within metapopulations may also lead to a reduction in the capacity of populations to withstand climate variability and change. At the ecosystem level, reduced complexity by elimination of species, such as might occur by fishing, may be destabilizing and could lead to reduced resilience to perturbations. Differential exploitation of marine resources could also promote increased turnover rates in marine ecosystems, which would exacerbate the effects of environmental changes. Overall (and despite the specificities of local situations) reduction in marine diversity at the individual, population and ecosystem levels will likely lead to a reduction in the resilience and an increase in the response of populations and ecosystems to future climate variability and change. Future management schemes will have to consider the structure and functioning of populations and ecosystems in a wider sense in order to maximise the ability of marine fauna to adapt to future climates.

Résumé : International audience
Semantic web standards, tools, ontologies and related technologies have considerably matured in the recent years. Nowadays, accessing a wide catalogue of biological, social, environmental, and ecological data sources helps stakeholders working on biodiversity to answer their complex questions. Will the real time access to web resources effectively support the definition of strategies to conserve and manage biodiversity? How might semantic web technologies help us to handle the complex and heterogeneous big data related to biodiversity? The workshop aims to identify the key challenges faced by the bioinformatics community, discuss potential solutions and identify the opportunities emerging from the trans-disciplinary interactions between Plant Science and Informatics experts. Therefore, we expect the bioinformatics experts to explain how they apply semantic web standards and tools to their scientific topic, from biology, agriculture, agro-ecology, genomics, environmental studies, to social sciences, citizen sciences. Research papers presenting various aspects of semantic web technologies applied to biodiversity data, ranging from position papers to implemented systems descriptions and their evaluation, will be selected. We are particularly interested in the use of the semantic technologies to design and develop systems that supports research on agricultural and wild biodiversity conservation and management for food security. Examples may include strategies for resilience to climate change pressures, sustainability of productive ecosystems, ecosystems services monitoring or territories management, rather than systems supporting only research on climate patterns or soil erosion.

Résumé : The Gold Coast in Australia is one of these coastal places, which developed through taking advantage of its environmental assets, such as direct access to the sea, a white sandy shoreline, an extensive and naturally protected broadwater and several large accessible rivers. While many other coastal cities relied on port facilities to develop commercial and naval activities, the City of Gold Coast emerged and grew as a tourism destination. Largely because of this phenomenon, the pattern of settlement and subsequent development of the city differs from most traditional Australian settlement and development patterns. Today, the Gold Coast is one of the most famous tourist cities in Australia and it accommodates more than ten million visitors annually.In the wider Australian context, 85% of the population lives within 50 km of the beach, evidencing popular lifestyle cultural preferences of many Australians. Given this preoccupation with the coast, one may expect that Australia would be at the forefront of coastal tourism developments and coastal protection. There is, however, no overriding jurisdiction covering planning law enforcement in maritime areas and, this situation has led to many social and environmental conflicts. The City of Gold Coast is a case in point and no more so than currently (2017) with proposals to build a cruise terminal or/and a casino, and high rise residential towers on its protected coastal strip (the Spit).This paper demonstrates how the evolution and resolution of development conflicts on the Spit (Gold Coast) are symptomatic of the evolution of place values and the national coastal management and how, this informs a shift towards coastal protection.
La ville côtière de Gold Coast, en Australie, s’est développée grâce à un environnement naturel exceptionnel, qui comprend un accès direct à la mer, un littoral de sable blanc, une large baie naturellement protégée et plusieurs rivières. Si la plupart des autres villes du littoral australien se sont appuyées sur leur port pour développer leurs activités commerciales et navales, la ville de Gold Coast est, depuis ses débuts, une ville touristique. De ce fait, son mode et ses formes de développement se différencient de ceux que l’on rencontre traditionnellement dans les autres villes. Aujourd’hui la ville de Gold Coast est l’une des principales destinations touristiques australiennes et accueille plus de dix millions de visiteurs par an.En Australie, 85% de la population habite dans un rayon de 50km de la plage, avec les préférences de style de vie qui y sont associées. Vu cette attraction pour le littoral, on pourrait présumer que l’Australie soit à l’avant-garde des développements touristiques et de la protection de son littoral. Cependant, du point de vue national, comme, historiquement, il n’y a eu qu’une faible jurdiction concernant l’aménagement et la protection des zones maritimes et du littoral, de nombreux conflits sociaux et environmentaux ont vu le jour. La ville de Gold Coast concentre malheureusement nombre de ces conflits ; le dernier en date concernant le projet de construction d’un terminal de bateaux de croisière et/ou d’un casino avec quelques tours residentielles sur une langue de terre protégée (le Spit).L’objectif de cet article est de montrer comment l’évolution et la résolution des conflits sur le Spit de Gold Coast, tous liés à des projets de développements touristiques, reflètent non seulement l’évolution de la valeur d’un lieu et l’approche nationale du développement du littoral, mais aussi le changement vers une meilleure protection du littoral.

Résumé : The patterns of variations in fisheries time series are known to result from a complex combination of species and fisheries dynamics all coupled with environmental forcing (including climate, trophic interactions, etc.). Disentangling the relative effects of these factors has been a major goal of fisheries science for both conceptual and management reasons. By examining the variability of 169 tuna and billfish time series of catch and catch per unit effort (CPUE) throughout the Atlantic as well as their linkage to the North Atlantic Oscillation (NAO), we find that the importance of these factors differed according to the spatial scale. At the scale of the entire Atlantic the patterns of variations are primarily spatially structured, whereas at a more regional scale the patterns of variations were primarily related to the fishing gear. Furthermore, the NAO appeared to also structure the patterns of variations of tuna time series, especially over the North Atlantic. We conclude that the patterns of variations in fisheries time series of tuna and billfish only poorly reflect the underlying dynamics of these fish populations; they appear to be shaped by several successive embedded processes, each interacting with each other. Our results emphasize the necessity for scientific data when investigating the population dynamics of large pelagic fishes, because CPUE fluctuations are not directly attributable to change in species' abundance.

Résumé : International audience
Different marine habitats are characterised by different soundscapes. How or which differences may be representative of the habitat characteristics and/or community structure remains however to be explored. A growing project in passive acoustics is to find a way to use soundscapes to have information on the habitat and on its changes. In this study we have successfully tested the potential of two acoustic indices, i.e. the average sound pressure level and the acoustic complexity index based on the frequency spectrum. Inside and outside marine protected areas of Moorea Island (French Polynesia), sound pressure level was positively correlated with the characteristics of the substratum and acoustic complexity was positively correlated with fish diversity. It clearly shows soundscape can be used to evaluate the acoustic features of marine protected areas, which presented a significantly higher ambient sound pressure level and were more acoustically complex than non-protected areas. This study further emphasizes the importance of acoustics as a tool in the monitoring of marine environments and in the elaboration and management of future conservation plans. Coral reef ecosystems are among the most biologically diverse and complex marine ecosystems worldwide. In addition to their biological and ecological importance, coral reefs support major economic and physical functions (e.g. food production, tourism, biotechnology development and coastal protection) that are essential for many countries 1. Unfortunately, coral reefs are severely threatened: 20% of coral reefs can no longer be defined as such, another 25% are currently endangered and another 25% will be endangered by 2050 2. The frequency and severity of natural perturbations (e.g. cyclone, outbreaks of predators, particularly the crown-of-thorns starfish [COTS] Acanthaster planci) and anthropogenic perturbations (e.g. ocean acidification, pesticides, rising seawater temperatures) on coral reefs have greatly increased worldwide in the last three decades, and, as a consequence, reef communities (fish, coral and benthic invertebrates) have suffered unprecedented levels of decline 3,4
