Résumé : Cet article traite de la spécificité de l’activité touristique à Bali, fondée sur une identité locale forte et un riche patrimoine naturel et culturel mais aussi troublante en raison de l’importance et la complexité des jeux d’acteurs, ou encore des contextes sociaux, religieux et géopolitiques propres à ce territoire insulaire. Nous analyserons les liens pérennes ou non entre patrimoine et développement en focalisant sur ce qui fait l’image de marque de Bali sur les plans touristique et politique : le tourisme culturel. Cette étude de cas illustre les dynamiques d’acteurs dans le cadre de l’île de Bali où l’on constate une forte imbrication entre tourisme international, protection de l’environnement et promotion du patrimoine culturel. Vendue comme un paradis tropical, perçue comme l'île des Dieux, Bali se voit contrainte de mesurer les risques d'un tourisme culturel qui se transformerait trop rapidement en culture touristique. Des pistes seront proposées afin d’encourager l’ensemble des acteurs à œuvrer pour que le « dernier paradis » (last paradise) ne devienne pas un « paradis perdu » (lost paradise).
Since the 1930s, Bali has been generally seen as a traditional tourism destination quite fashionable. Nowadays, a new kind of tourism, rather esoteric if not totally spiritual, is emerging on this small “paradise” often referred as a natural untouched and cultural preserved island. To attire more international tourists, the “Island of Gods”, as the tourism promoters still name this tropical holiday paradise, is now also targeting on the industry of “well-being”. This article deals about the specificity of the local tourism activity which is based on a strong cultural identity and a rich natural and also religious heritage. Uncontrolled development of this predatory industry brings also a lot of new problems, such as pollution or acculturation. Here, our aim is to focus and analyse the real and false ties between heritage, development and tourism, always by keeping in mind that the regional motto about tourism policy still is to encourage “cultural tourism” as a real model (a “brand”, in fact) of success. We especially try to explain, in this current work (still in progress), the touristic situation in the main cultural site located on the island: Ubud. This small city, really boosting during the last decade, is worldwide reputed for the rich cultural performances and seen as “the” artistic capital of Bali. Ubud offers also a perfect example of an intense and dynamic bond between cultural heritage and economic development. Often for the best and sometimes also for the worse. In this rural but international spot, it seems that tourism business allows the local population to live in better ways and, sometimes, even to reborn, culturally speaking! Our case study shows also the big threats behind the current tourism policy: the large scale business occurred by globalization and all the tourism opportunities thus provided cannot hide the real weakness that for sure also concern the balinese way of thinking and living. Cultural tourism could rapidly be transformed in a dangerous kind of tourism of the culture, with all the big (and bad) changes the Balinese don’t want to see happening on their lovely and holy island. So, the present reflection conducts us to think more deeply on some new and alternative ways of developing tourism in Bali. Finally, our aim is to think, first by listening to the desire of the Balinese themselves, in which best manner this “last paradise” will not become a “lost paradise”.

Résumé : This paper aims to explore the complex relationships between international tourism and the production and exchange of 'nature' in tropical countries. It is based on data gathered through an ethnographic case study approach on the changing aesthetic, economic and symbolic values attached to the coral reef in the tropical island of La Réunion, Indian Ocean. The analysis of this data shows that, from the point where the collective imaginaries in the Western world associate a 'magic' value with corals, an international institutionalisation process takes place in order to protect and preserve coral reefs and make them touristically accessible. This raises important issues related to the challenges the new value of tropical nature represents for the communication and exchange systems of communities in tropical countries. The paper first explores the meanings of the spiritual and religious value Western societies attribute to coral reefs. It then discusses the institutionalisation of tropical nature by international organisations and the problem of parallel land and natural space ownership systems in La Réunion. After that, it deconstructs the mystification policy of the coral reef operated by local institutions in La Réunion and examines the meaning of protecting the coral reef as a socially embedded 'communicative action' in La Réunion.
L’objectif de cette étude est d’explorer les relations complexes entre d'une part le tourisme international et d'autre part la production et l'échange de 'nature' dans des pays tropicaux. L'étude est basée sur des données recueillies à travers une approche ethnographique des valeurs esthétiques, économiques et symboliques attachées au récif corallien de l'île de La Réunion, dans l'océan Indien. L'analyse de ces données montre qu'à partir du moment où les imaginaires collectifs de l'Occident associent les coraux à une valeur 'magique', un processus d'institutionnalisation internationale s’engage dans le but de protéger, préserver et rendre accessibles au tourisme les récifs coralliens. Ceci implique des problématiques importantes liées à la mise à l'épreuve des systèmes de communication et d'échange des sociétés dans les pays tropicaux. L'étude explore d'abord la signification des valeurs spirituelles et religieuses qu'attribuent les sociétés occidentales aux récifs coralliens. Ensuite, elle discute l'institutionnalisation de la nature tropicale par des organisations internationales ainsi que le problème de l'existence de différents systèmes de gestion foncière à La Réunion. Enfin, l'étude déconstruit la politique de mythification du récif corallien mise en œuvre par des institutions locales à La Réunion et examinera la signification de 'protéger l'environnement' en tant qu'action communicante définie par les systèmes de communication et d'échange réunionnais.

Résumé : In January and February 2002, the presence of certain agricultural pesticides throughout the coastline of the Caribbean island of Martinique was investigated. The tropical climate of the French West Indies is suitable for banana production, which requires intensive use of pesticides. An inventory of all pesticides used on the island (compounds and tonnage) was compiled. Surveys and analyses revealed the presence of pesticides in the plumes of seven rivers. The organochlorine chlordecone and metabolites of aldicarb were detected at nearly all of the monitored sites, even though the use of chlordecone has been prohibited since 1993. Two triazines (ametryn and simazine) were also identified. The concentrations of carbamates and triazines detected in the water and sediment samples from Martinique are comparable to those reported for mainland France. Chlordecone concentrations in the sediment and particulate matter samples were, however, particularly high in the samples from Martinique. Toxicological implications are discussed. Of particular concern are the high levels of chlordecone (which is bioaccumulating and carcinogenic) and further monitoring of this compound is recommended, especially in fish and other sea-food products.

Résumé : International audience
Marine ecosystems cover about 70% of the planet surface and are still an underexploited source of useful metabolites. Among microbes, filamentous fungi are captivating organisms used for the production of many chemical classes of secondary metabolites bound to be used in various fields of industrial application. The present study was focused on the collection, isolation, screening and genotyping of pigmented filamentous fungi isolated from tropical marine environments around La Réunion Island, Indian Ocean. About 150 micromycetes were revived and isolated from 14 marine samples (sediments, living corals, coral rubble, sea water and hard substrates) collected in four different locations. Forty-two colored fungal isolates belonging to 16 families, 25 genera and 31 species were further studied depending on their ability to produce pigments and thus subjected to molecular identification. From gene sequence analysis, the most frequently identified colored fungi belong to the widespread Penicillium, Talaromyces and Aspergillus genera in the family Trichocomaceae (11 species), then followed by the family Hypocreaceae (three species). This study demonstrates that marine biotopes in La Réunion Island, Indian Ocean, from coral reefs to underwater slopes of this volcanic island, shelter numerous species of micromycetes, from common or uncommon genera. This unstudied biodiversity comes along with the ability for some fungal marine inhabitants, to produce a range of pigments and hues.

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

Expedition Pakaihi I Te Moana was conducted in 2011 to the Marquesas Islands, lying between 07°50ʹ S and 10°35ʹ S latitude and 138°25ʹ W and 140°50ʹ W longitude. The expedition combined extensive collections and visual censuses of the shore fish fauna. A total of 74 species are added as new records for the Marquesas Islands; the coastal fish fauna of the Marquesas Islands is increased from 415 to 495 species and the number of endemic species is increased from 48 to 68 species. This increases the percentage of species-level endemism for the Marquesas Islands to 13.7%, ranking as the third highest region of endemism for coral reef fishes in the Indo-Pacific. Only two other peripheral regions, the Hawai'ian Islands and Easter Island, have higher values.

Résumé : The problems caused by venomous fish in the waters of the Lesser Antilles were studied in two notes published by the state-run Technical Assistance and Social Credit Company (SATEC) and in older works by Poey (1866), Arcisz (1950) and Randal (1958). The first SATEC note gives the brief description and classification of venomous coastal fishes of St. Barthelemy; the other SATEC note explores the hypotheses on the origin of venomousity of tropical fish based on a vast literature review (Morice, 1961, 1962). It also gives in the appendix a complete list of "fearful" species (this is how venoumous fish are designated in the local language and the "ciguatera" is called a "hurt fish") in St. Barthelemy waters and reports the cases of poisoning studied on the island since September 1960.In October 1963, we carried out a short expedition to St. Martin, during which we established equivalences between local names used by the inhabitants of St. Barthelemy and St. Martin to designate dangerous species. Moreover, thanks to kind help by a doctor at the Marigot hospital, we were able to note details on the symptoms from a series of serious poisonings that occurred at Marigot and surrounding areas in July-August 1963. The species incriminated by the victims of this poisoning had been caught in the south-west of the "Ile des Chiens" situated in the north-west of St. Martin and were all part of the list previously established for St. Barthelemy.
Les problèmes posés par la vénénosité de certains poissons des eaux des Petites Antilles ont fait l'objet, en de:hors de travaux anciens de POEY, 1866 à ARCISZ, 1950 et RANDALL, 1958) de deux notes ronéotypées par les services de la S.A.T.E.C. L'une concerne la description rapide et la classification des poissons côtiers vénéneux de l'île de St-Barthélémy; l'autre étudie les théories émises à propos de l'origine de la vénénosité des poissons tropicaux, ceci après compilation de la vaste littérature parue à ce sujet (MORICE, 1961 : 1962) ; elle donne également en annexe la liste complétée des espèces « redouteuses » des eaux de St-Barthélémy avec notification des cas d'empoisonnement étudiés dans l'île depuis septembre 1960 (c'est en effet par ce qualificatif que les poissons vénéneux sent désignés dans le patois de St-Barthélémy, et la « ciguatera)) est appelée « mal poisson ))). En octobre 1963, nous avons effectué une courte mission d'étude à St-Martin, séjour au cours duquel nous avons pu établir l'équivalence des noms vernaculaires utilisés par les habitants de St-Barthélémy et de St-Martin pour désigner les espèces dangereuses; de plus, grâce au concours aimable du médecin de l'hôpital de Marigot, nous avons pu noter les détails symptomatologiques d'une série d'intoxications graves survenues à Marigot et clans ses environs en juillet-août 1963. Les espèces incriminées par les victimes de cette intoxication avaient été capturées dans le sud-ouest de l'îlot des Chiens, dans le nord-ouest de St-Martin et faisaient toutes partie de la liste établie précédemment pour St-Barthélémy.

Résumé : International audience
Despite their importance in marine biodiversity, invertebrates are far less studied than vertebrates. Given the current globalbiodiversity crisis and insufficient taxonomic resources, sustained efforts need to be undertaken to assess species diversity,especially in the highly threatened ‘biodiversity hotspots’. Réunion is a young volcanic island lying in the Mascarene Islands(south-western Indian Ocean, SWIO), a marine biodiversity hotspot. A substantial sampling effort was conductedaround Réunion Island to document shallow water reef-associated ophiuroid (brittle-stars) diversity, a class recognised asthe most diverse among echinoderms. A total of 33 species were documented, increasing the known species richness ofthe island by 56%. Findings include 15 new records for Réunion, 11 for the Mascarene Islands and 8 for the Indian Ocean.The most diverse family was Ophiocomidae, a family of large, abundant and conspicuous tropical species. Even in thiswell studied family, a new species was revealed by this survey. Morphological variants together with DNA sequence variationswithin several species revealed cryptic species. We compared our results with the known fauna of other MascareneIslands and discuss biogeographic implications for the region.

Résumé : A new benthic phototrophic dinoflagellate is described from sediments of a tropical marine cove at Martinique Island and its micromorphology is studied by means of light and electron microscopy. The cell contains small golden-brown chloroplasts and the oval nucleus is posterior. It is laterally compressed, almost circular in shape when viewed laterally. It consists of a small epitheca tilted toward the right lateral side and a larger hypotheca. In the left view, the cingulum is more anterior and the epitheca is reduced. The cingulum is displaced and left-handed. This organism is peculiar in having no apical pore and its thecal plate arrangement is 2 ' 1a 7 '' 5c 3s 5 ''' 1 ''''. The plates are smooth with small groups of pores scattered on their surface. An area with 60-80 densely arranged pores is found near the centre of the 2 ''' plate, on the left lateral side. Morphologically, these features are different from all other laterally compressed benthic genera. In addition, molecular genetic sequences of SSU and partial LSU form a distinct and well-supported clade among dinoflagellates and support the erection of a new genus. However, molecular phylogenies inferred from ribosomal genes failed to confirm any clear relationship with other benthic taxa and affinity with other laterally compressed dinoflagellates has not been demonstrated. Hence, the taxonomic affinity of Madanidinium loirii with a defined order and family is unclear at the moment.

Résumé : Due to favourable environmental conditions and political will, marine fish farming has developed recently around the Mediterranean. The Mediterranean area is characterised by a large number of islands which are extremely diversified from geographical, political or socioeconomic point of views. As a matter of fact, it turns out that almost a third of the Mediterranean fish farming production comes from these islands which have proven to offer good conditions for the development of that new activity. The reasons why somany enterprises have been established on islands are very diverse. Taking advantage of good environmental conditions is the most common motivation, since islands are usually less submitted to constraints due to town extension, industry development or intensive agriculture. Moreover, as far as European Union countries are concerned, incentive policy towards ultraperipheral or late development regions has made it possible to attribute specific subsidies to islands for aquaculture in the aim of more employment and wealth. Like any other economic activity, aquaculture has to face some specific constraints due to the insular context. Transport to and from the islands is more expensive and less regular, which has a negative impact on the price competitiveness of the insular products. Local markets are often too small to make it possible for the enterprises to develop first at a domestic level and to take advantage of economies of scale. Thanks to their positive and attractive world-wide image, Mediterranean islands could promote the quality of their products on the basis of geographical origin, of quality of the environment or of specific production processes. Information networks implementation and marketing approach in terms of image are challenges Mediterranean islands have to take up in order to supply the large European seafood market with quality products.

Grâce à de bonnes conditions de milieu et à une volonté politique affirmée, l'élevage des poissons marins s'est développé récemment dans la Méditerranée. Le bassin méditerranéen possède un très grand nombre d'îles qui sont très diverses de par leur caractéristiques géographiques, politiques ou socio-économiques. Près du tiers de la production de poissons marins d'élevage des pays méditerranéens est réalisée dans des îles. Les raisons qui ont incité tant d'entreprises à s'établir sur des îles sont diverses. La motivation principale avancée par les promoteurs de l'aquaculture insulaire méditerranéenne est la qualité de l'environnement des îles et la disponibilité en sites, justifiée par le fait que les îles sont moins soumises à certaines contraintes comme l'extension des villes, le développement de zones industrielles ou l'intensification de l'agriculture. La politique d'aide envers les régions ultra-périphériques ou en retard de développement a permis d'attribuer des subventions spécifiques aux îles pour développer l'aquaculture dans un objectif de création de richesse et d'emploi. Comme toute autre activité économique dans les îles, l'aquaculture doit faire face à des contraintes directement liées à l'insularité. Le transport est plus coûteux et moins régulier, ce qui a un effet négatif sur la compétitivité prix des produits. Les marchés locaux sont souvent trop petits pour permettre aux entreprises de se développer d'abord en interne et de profiter d'économies d'échelle. Une réponse possible à cette contrainte de concurrence internationale pourrait être la promotion des produits sur la base de l'origine géographique,de la qualité de l'environnement ou de procédés de production spécifiques afin de valoriser l'image très positive et la notoriété de ces îles dans le monde entier. Les réseaux dédiés à l'information, à la recherche et au transfert technologique sont des outils nécessaires pour compenser les contraintes dues à la petite taille et à l'isolement dans le but de fournir le vaste marché européen en produits de la mer de qualité.

Résumé : International audience
Tropical islands are characterized by thermal and orographical forcings which may generate microscale air mass circulations. The Lesser Antilles Arc includes small tropical islands (width lower than 50 km) where a total of one-and-a-half million people live. Air quality over this region is affected by anthropogenic and volcanic emissions, or saharan dust. To reduce risks for the population health, the atmospheric dispersion of emitted pollutants must be predicted. In this study, the dispersion of anthropogenic nitrogen oxides (NOx) is numerically modelled over the densely populated area of the Guadeloupe archipelago under weak trade winds, during a typical case of severe pollution. The main goal is to analyze how microscale resolutions affect air pollution in a small tropical island. Three resolutions of domain grid are selected: 1 km, 333 m and 111 m. The Weather Research and Forecasting model (WRF) is used to produce real nested microscale meteorological fields. Then the weather outputs initialize the Lagrangian Particle Dispersion Model (FLEXPART). The forward simulations of a power plant plume showed good ability to reproduce nocturnal peaks recorded by an urban air quality station. The increase in resolution resulted in an improvement of model sensitivity. The nesting to subkilometer grids helped to reduce an overestimation bias mainly because the LES domains better simulate the turbulent motions governing nocturnal flows. For peaks observed at two air quality stations, the backward sensitivity outputs identified realistic sources of NOx in the area. The increase in resolution produced a sharper inverse plume with a more accurate source area. This study showed the first application of the FLEXPART-WRF model to microscale resolutions. Overall, the coupling model WRF-LES-FLEXPART is useful to simulate the pollutant dispersion during a real case of calm wind regime over a complex terrain area. The forward and backward simulation results showed clearly that the subkilometer resolution of 333 m is necessary to reproduce realistic air pollution patterns in this case of short-range transport over a complex terrain area. Globally, this work contributes to enrich the sparsely documented domain of real nested microscale air pollution modelling. This study dealing with the determination of the proper resolution grid and proper turbulence scheme, is of significant interest to the near-source and complex terrain air quality research community.

Résumé : International audience
Assessing population connectivity is necessary to construct effective marine protected areas. This connectivity depends, among other parameters, inherently on species dispersal capacities. Isolation by distance (IBD) is one of the main modes of differentiation in marine species, above all in species presenting low dispersal abilities. This study reports the genetic structuring in the tropical hydrozoan Macrorhynchia phoenicea (sensu Postaire et al., 2016a), a brooding species, from 30 sampling sites in the Western Indian Ocean and the Tropical Southwestern Pacific, using 15 microsatellite loci. At the local scale, genet dispersal relied on asexual propagation at short distance, which was not found at larger scales. Considering one representative per clone, significant positive F-IS values (from -0.327*** to 0.411***) were found within almost all sites. Gene flow was extremely low at all spatial scales, among sites within islands (<10km distance) and among islands (100 to >11,000km distance), with significant pairwise F-ST values (from 0.035*** to 0.645***). A general pattern of IBD was found at the Indo-Pacific scale, but also within ecoregions in the Western Indian Ocean province. Clustering and network analyses identified each island as a potential independent population, while analysis of molecular variance indicated that population genetic differentiation was significant at small (within island) and intermediate (among islands within province) spatial scales. As shown by this species, a brooding life cycle might be corollary of the high population differentiation found in some coastal marine species, thwarting regular dispersal at distances more than a few kilometers and probably leading to high cryptic diversity, each island housing independent evolutionary lineages.
