Résumé : The green turtle (Chelonia mydas) is an emblematic species of marine life. However, nowadays it is subject to many threats (poaching, by-catch). Even if there is deep growing measures for its protection, the green turtle still is an endangered species and it is listed in Appendix I of Washington Convention (CITES). In order to elaborate efficient conservation and management plans, perfect knowledge of green turtle biology, but also of its population structure and their characteristics, are needed. In this thesis, we have assessed genetic structure of green turtle populations in the South-Western Indian Ocean by using genetic tools. In all, 1551 tissue samples have been collected from our study zone and from our control site French Polynesia (37 samples). All kinds if individuals were sampled (except males in reproductive phase) from 15 sampling sites including nesting, foraging, and immature development site. We used both control region of mitochondrial DNA and 6 microsatellite loci to better infer maternal and paternal lineages. We identified 29 haplotypes in the South-Western Indian Ocean. They are distributed in 3 independent and highly divergent clades, including one composed with haplotypes from Atlantic Ocean. For 7 of these haplotypes, it was the first time they were detected in the study zone. Fifteen haplotypes were previously undescribed, distributed in all the 3 clades. These new haplotypes seem to be specific to the South-Western Indian Ocean, which is then an original zone. Besides, we found a high allelic richness. These results show the South-western Indian Ocean is rich and very diversified. This region plays an important role in the global diversity of the species. The South-Western Indian Ocean is one of the two contact zones presently known between the two metapopulations of green turtles (Atlantic-Mediterranean and Indo-Pacific). This contact induces a genetic cline based on CM8 (Atlantic) and C3 (Indo-Pacific) haplotype frequencies. Analysis of the microsatellite differentiation between individuals provides evidence of genetic exchanges between the two metapopulations in the region. The South-Western Indian Ocean participates to green turtle global genetic mixing. Studying the influence of several intrinsic and extrinsic factors on population structuring provides useful information for management plan elaboration. We found no significant difference between genetic structures of foraging females and males, contrary to immature turtles which seem to be organised in 'regional pools'. This organisation could be due to both immature natal homing and influence of oceanic currents. High mitochondrial differentiation of nesting females and low global microsatellite differentiation of our samples indicate male-mediated gene flow among populations of the study zone. The genetic composition of a sampling site presents no significant variation along the year, even if we could notice some trends. Nevertheless, it can be significantly different from a year to an other one. This may result from alternation of distinct populations on the same site. We noticed different evolution in 10 or 20 years of the genetic composition depending on the sampling site. Geographic distance seems not to have significant influence on population structuring concerning microsatellite markers. Nesting females of Saziley Beach (Mayotte Island, Comoros Archipelago) present genetic divergence from females nesting in the two other sampled beaches of this island. The observed population structure shows no contradiction with the organisation of oceanic currents in the South-Western Indian Ocean. Comparing the results from the two genetic markers used, we identified 8 genetic differentiated clusters of turtles in the study zone and at least 6 distinct populations. These clusters constitute 8 potential management units (MUs) which could serve as basis in the elaboration of conservation and management plans.
La tortue verte (Chelonia mydas) constitue l'un des espèces emblématiques de la vie marine, pourtant de nombreuses menaces pèsent de nos jours encore sur sa survie (braconnage, captures accidentelles). Ainsi, malgré l'essor de mesures de protection menées à travers pour sa sauvegarde, la tortue verte constitue une espèce 'en danger d'extinction' et figure dans l'Annexe I de la Convention de Washington (CITES). Afin d'élaborer des plans de gestion et de conservation qui soient efficaces, il est important d'avoir une parfaite connaissance de la biologie de la tortue verte, mais aussi de la structure de ses populations et de leurs caractéristiques. C'est dans ce cadre que s'inscrit la présente étude. L'objectif de cette étude était d'acquérir des connaissances sur la structure des populations de tortues vertes dans le sud-ouest de l'océan Indien grâce à l'utilisation de l'outil génétique. Au total, 1551 échantillons de tissu ont été collectés dans la zone d'étude et dans notre site témoin la Polynésie française (37 échantillons). Toutes les catégories d'individus ont été échantillonnées (excepté les mâles en phase de reproduction) et les 15 sites d'échantillonnage comprennent à la fois des sites de ponte, d'alimentation et de développement pour les immatures. Deux types de marqueurs ont été utilisés : la région contrôle de l'ADN mitochondrial et 6 loci microsatellites, afin d'appréhender au mieux l'apport des lignées maternelles et paternelles. Nous avons pu mettre en évidence la présence dans le sud-ouest de l'océan Indien de 29 haplotypes distincts, appartenant à trois clades fortement divergents dont l'un constitué d'haplotypes originaires de l'océan Atlantique. Parmi ces haplotypes, 7 ont été détectés pour la première fois dans la zone d'étude, et 15 autres n'ont jamais été précédemment décrits chez cette espèce. Ils sont présents dans chacun des 3 clades d'haplotypes. Ces nouveaux haplotypes semblent spécifiques à la région, et en font une zone originale. On observe par ailleurs une grande richesse allélique dans les effectifs analysés. Ces résultats montrent que le sud-ouest de l'océan Indien est une zone riche et très diversifiée. Cette région joue un rôle important dans la diversité génétique globale de l'espèce. Le sud-ouest de l'océan Indien constitue l'une des deux seules zones connues à l'heure actuelle de contact entre les deux métapopulations de tortues vertes (Atlantique-Méditerranée et Indo-Pacifique). Ce contact a entraîné la formation d'un cline génétique portant principalement sur les fréquences relatives des haplotypes CM8 (Atlantique) et C3 (Indo-Pacifique). Les résultats obtenus lors de l'analyse microsatellite de la différenciation entre les individus originaires des deux métapopulations montrent que le sud-ouest de l'océan Indien constitue une zone d'échanges génétiques entre les deux métapopulations, participant au brasage génétique de l'espèce. L'étude de facteurs, intrinsèques et extrinsèques, pouvant influencer la structuration des populations apportent de nombreuses informations qui pourraient s'avérer utiles lors de l'élaboration de plans de gestion. La structure des femelles et des mâles en alimentation ne diffère pas, contrairement à celle des immatures qui semble s'organiser en 'pools régionaux' qui seraient le fruit de l'interaction d'un comportement de philopatrie et d'une influence des courants océaniques. La forte différenciation mitochondriale des femelles en ponte et la très faible différenciation microsatellite observée à l'échelle de la région, indiquent l'existence de flux de gènes via les mâles. La composition génétique d'un site ne varie pas de manière significative au cours de l'année. Par contre, elle peut varier d'une année à l'autre, signifiant l'alternance dans certains sites de ponte de plusieurs populations distinctes. L'évolution de la composition génétique d'un groupe, au cours de 10 ou 20 ans, diffère selon le site considéré. La distance ne semble pas influencer de manière significative la structuration des populations au niveau microsatellite. Les femelles en ponte sur la plage de Saziley (Mayotte) diffèrent génétiquement de celles pondant sur les deux autres plages de l'île. La structure observée des populations est en accord avec l'organisation des courants océanique dans la région. La confrontation des résultats obtenus à partir des deux marqueurs génétiques utilisés, permet la détermination de 8 ensembles génétiquement différenciés dans la zone d'étude et l'identification d'au moins 6 populations distinctes. Ces ensembles constituent autant d'unités de gestion (MUs) potentielles qui pourront servir de base à l'élaboration de plans de gestion et de conservation.

Picture was taken from Prado Street. El Capitolio, or National Capital Building was built between April 1, 1926 and May 20, 1929. Many of the best Cuban architects joined forces on the project.
In 1925, Gerardo Machado was elected president. Soon afterward under the mandate of the legislature he commissioned a new design from the Cuban architects Raul Otero and Eugenio Raynieri. The previous, partially completed building was demolished and work began on the new building on 1 April 1926. Construction was overseen by the U.S. firm of Purdy and Henderson.

Résumé : International audience
Although migratory pelagic fishes generally exhibit little geographic differentiation across oceans, as expected from their life-history (broadcast spawning, pelagic larval life, swimming ability of adults) and the assumed homogeneity of the pelagic habitat, exceptions to the rule deserve scrutiny. One such exception is the narrow-barred Spanish mackerel (Scomberomorus commerson), where strong genetic heterogeneity at the regional scale has been previously reported. We investigated the genetic composition of S. commerson across the Indo-West Pacific range using control-region sequences (including previously published datasets), cytochrome-b gene partial sequences, and eight microsatellite loci, to further explore its phylogeographic structure. All haplotypes sampled from the Indo-Malay-Papua archipelago (IMPA) and the southwestern Pacific coalesced into a clade (Clade II) that was deeply separated (14.5% nucleotide divergence) from a clade grouping all haplotypes from the Persian Gulf and Oman Sea (Clade I). Such a high level of genetic divergence suggested the occurrence of two sister-species. Further phylogeographic partition was evident between the western IMPA and the regions sampled east and south of it, i.e. northern Australia, West Papua, and the Coral Sea. Strong allele-frequency differences were found between local populations in the southwestern Pacific, both at the mitochondrial locus (ΦST=0.282-0.609) and at microsatellite loci (^θ=0.202-0.313). Clade II consisted of four deeply divergent subclades (9.0-11.8% nucleotide divergence for the control region; 0.3-2.5% divergence at the cytochrome b locus). Mitochondrial sub-clades within Clade II generally had narrow geographic distribution, demonstrating further genetic isolation. However, one particular haplogroup within Clade II was present throughout the central Indo-West Pacific; that haplogroup was found to be sister-group to an haplogroup restricted to West Papua and the Coral Sea, yielding evidence of recent secondary westward colonization. Such a complex structure is in sharp contrast with the generally weak phylogeographic patterns uncovered to date in other widely distributed, large pelagic fishes with pelagic eggs and larvae. We hypothesize that in S. commerson and possibly other Scomberomorus species, philopatric migration may play a role in maintaining the geographic isolation of populations by annihilating the potential consequences of passive dispersal.

Résumé : International audience
The French education system remains highly centralized and only allows limited local adaptations for overseas territories. For example, if some laws (the last in 2013) allow the use of regional languages (e.g. Creole in the French West Indies) when they constitute a relevant contribution to the teaching, many official texts remain mainly based on the geographical, economical, historical, environment of the French mainland. We focus on some French BTS (Brevet de Technicien Supérieur / Advanced Technician Certificate), namely tourism and assistant manager, which are two important diplomas for the local development and in which microeconomic and management sciences plays a great part. The French BTS is a professional diploma prepared in two years after the “baccalauréat”, with national programs and evaluation criteria. The successful candidates are supposed to be immediately employable, especially in their local geographical environment. Thus, there exists a paradox between the national definition of the diploma and the local contexts of teaching. We discuss how teachers concretely deal with this situation on a day-to-day basis. Our hypothesis is that they act pragmatically, using their practical pedagogical content knowledge, without theoretical support for their action. In order to verify this hypothesis, we have conducted semi-structured interview with Guadeloupian teachers of the two aforementioned BTS. The main results shows that teachers adapt the national framework of the diploma, essentially by using local examples. This can be called a weak contextualization of the national texts. Indeed, these adaptations remain limited by fear of disadvantaging the students for the national exam. In addition, many context effects are shown, for example linked with local rules (concerning VAT, custom duties...) which are only partially taken into account by teachers. This demonstrates that the French educative system has not yet completely solved the opposition between national guideline and decentralization of the educational action.

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
This paper deals with data structures within GIS. Continuous phenomenons are usually represented by raster structures for simplicity reasons. With such structures spatial repartitions of the data is not easily interpretable. Moreover, in an overlapping clustering context these structures remove the links between the data and the algorithms. We propose a vector representation of such data based on non-regular multi-rings polygons. The structure requires multipart nested polygons and new set operations. We present the formalism based on belief theory and uncertainty reasoning. We also detail the implementation of the structures and the set operations. The structures and the set operations are illustrated in the context of forest classification having diffuse transitions.

Résumé : After a period of rapid development of the sites (an increase in both reared surface area and production), tropical shrimp aquaculture is currently being faced with critical problems due to economical and ecological constraints. In many countries with favourable conditions for shrimp aquaculture such as indonesia or Vietnam, sites are often badly selected and/or over-exploited. This conducts to sorne extent to decreases or collapses in the production due to the difficulty in predicting the maximum production capacity of the sites. Furthermore, it appears that production sustainability depends on many factors among which socio-economy and ecolo gy are of prime importance. The STD3 project titled « Assessment of tropical shrimp aquaculture impact on the environment in tropical countries using hydrobiology, ecology and remote sensing as helping tools for diagnosis )) was initiated in 1994, with the aim to study the sustainability of marine shrimp aquaculture in tropical areas, main! y Indonesia and Vietnam, through the following tasks: (i) improve site selection and study the impact of aquaculture on marine environments presenting a variable sensitivity to organic sewage, (ii) analyse the socio-economical aspects and profitability of the aquaculture industry and of common resources (iii) use remote sensing and geographical data bases for diagnosis and monitoring of site degradation (iv) reinforce the capacity of Asian scientists through training. Severa! aquaculture sites have been investigated in the Lampung region (South Sumatra, Indonesia), the Mekong delta (Vietnam) and on the West coast of New-Caledonia, providing a large range of typical ecosystems encountered in Asia and in the Pacifie, from coralline sites to coastal plains with mangrove and deltaic areas. The study concerned the spatial structure and seasonal influence of these ecosystems, the temporal variation during the course of the project (3 years) and the relation between the ecological structure and farm productions. Remote sensing provides a synoptic vision over large land expanses. Severa! scenes were processed for landuse mapping using conventional classification techniques. Concerning water quality assessment, a general relation for the Java sea was found between image and field data in terms of total suspended matter. Applying this relation to a new site in Sumatra has provided an initial approach to water type and, together with land use mapping, a preliminary assessment of the suitability of the area to shrimp aquaculture development. Socio-economic research has been focused on the identification ofneeds for collective action, including public policy, in the perspective of shrimp farming sustainability. The main concern is in the regulation of shrimp farming intensification and extensification at the scale of coastal ecosystemic entities in a common property resource management perspective. The common considered here is coastal water quality. Comparing the local development profiles and the institutional grounds for the design and implementation of collective management rules shows that variables such as land tenure system, farm owner socio-economic profile, social homogeneity or heterogeneity of the farmers are key factors to analyse the potential for sustainability. The defmition of water quality and the possible means to ensure its collective management are discussed. The main conclusion is that the economie incentives to farming development are strong but there is no significant difference among traditional, semi-intensive and intensive systems in terms of economie efficiency or wealth distribution. The description of the functioning of the different kinds of ecosystems make it possible to give an advice concerning the positioning of the activity inside the ecosystem, and furthermore to have a reference state in order to determine the impact of the activity on the coastal environnement. This impact can be summarized as an increase in the concentration of total suspended matt€?r, of particulate organic matter and of sulfate reducing bacterias. This organic ma~.er is either issued from rearing activities or from telluric origine, due to mangrove eradication when building the ponds. An evaluation of the relationship existing between productivity and characteristics of each ecosystem bas been conducted by correlating ecological indicators data (concentration of total suspended matter, particulate organic matter, chlorophyll, percentage of pheopigments in total pigments and cyanobacteria and sulfatereducing bacteria in water and sediments) with the average production of the farms. This comparison lead to the compilation of a scale of observed production integrating the range of these environmental parameters with shrimp production levels, bound to facilitate the positioning of shrimp farming in relation with the confmement leve! of each ecosystem. Lastly, ali geographie data originated from the various compartments of the study have been geo-referenced and loaded into a geographical information system. This allows to display any query made on spatial variables and their related statistical data, including the ir variations over the last few years and to reveal patterns and phenomena otherwise not obvious.
Le programme mis en oeuvre par la DRV (Paris, CREMA-L'Houmeau, DELIAO Brest, COP Tahiti, GIE/RA Nouvelle Calédonie), dans le cadre d'un projet européen STD3 «(Sciences et Technique au Service du Développement», en collaboration avec l'Université de Montpellier II, l'Ecole Nationale d'Agronomie de Rennes, l'ITC (Hollande), l'Institut Océanographique de Nha Trang (Vietnam), le BADC de Jepara et le BPPT de Jakarta (Indonésie), avait pour but la mise au point de méthodes permettant d'améliorer la sélection des sites ainsi que le suivi du développement et de l'impact de l'aquaculture des crevettes Péneides en milieu tropical pour éviter la surexploitation. Quatre axes de recherche ont été défmis : a) identifier la nature et quantifier les rejets de déchets issus de ce type d'aquaculture, b) définir les caractéristiques écologiques des écosystèmes susceptibles d'accueillir l'activité aquacole et suivre leur évolution sous l'influence des rejets, c) déterminer l'influence de la gestion des fermes et des ressources (aspects économiques) sur les performances de productivité, d) déterminer la capacité de la télédétection comme outil de diagnostic d'impact à l'échelle de la région, e) mener un programme de formation d'étudiants et jeunes chercheurs Vietnamiens et Indonésiens.

Understanding genomic evolution in wild populations is of particular importance because evolution is a central process in our understanding of populations’ history and their future response to global changes. In addition to fundamental knowledge, the study of populations’ evolution has wide applications such as conservation/restoration genetics or epidemiology. Indeed, genetic diversity is the ‘fuel’ for populations’ evolution and adaptation to new conditions, and estimating the extent and the geographic structure of genetic diversity, as well as identifying the evolutionary forces behind (demography, gene flow, and adaptation) are thus major challenges in the current context of global changes. [br/]A particular attention is currently devoted to the process of genetic divergence in wild populations, with emphases on gene flow, local adaptation, and their interactions. Indeed, adaptation in wild populations is supported in many species by many kinds of experiments based on both quantitative phenotypic traits and molecular data. However, the processes governing populations’ evolution are poorly understood in the tropical rainforest of Amazonia, and the relative influence of neutral and adaptive processes are continuously discussed. [br/]I am a young scientist interested in the process of genomic divergence in wild (tree) populations. I aimed at understanding how evolution structures the genetic diversity and governs molecular divergence in wild populations, with particular emphases on gene flow and local adaptation. During five years as a young scientist, I worked on answering the following questions, focusing on two tree species occupying vulnerable areas: mainly [i]Eperua falcata[/i] in Amazonia and, to a lesser extent, [i]Abies alba[/i] in the Mediterranean area.[br/][u]Scientific questions:[/u][br/]- Which evolutionary drivers are responsible of the structure of genetic diversity in wild populations occupying wide areas? This question was addressed at different geographical scales: from large (regional) to very local (microgeographic) scales. [br/]- What is the relative influence of neutral (gene flow, inbreeding) and adaptive drivers in the process of genetic divergence?[br/]- Is microgeographic adaptation possible in spite of extensive gene flow between populations occupying the extreme boundaries of an ecological gradient? [br/]- What is the extent of natural selection in the (whole) genome of wild populations? [br/][br/]My research work is at the interface between three promising disciplines: Evolutionary genomics (i.e. the study of populations evolution and the evolutionary drivers behind), Bioinformatics (i.e. the treatment of next-generation data), and Bayesian modelling (i.e. the empirical calibration of complex mechanistic model). I intend to take advantage of the recent advances in sequencing and informatic technologies to bring up to date the field of ecological genetics and evolutionary biology, by developing modern research strategies to study the process of genomic divergence in wild populations.

Résumé : Ce numéro de la Revue Etudes Caribéennes consacré au tourisme vise à poser les bases d’une réflexion sur le fonctionnement des lieux touristiques, les programmes d’aménagement touristique et les différents enjeux pour les territoires. Lieu ouvert ou lieu fermé, flux concentré ou flux diffus, la nature du lieu touristique, avec ses pratiques, classiques ou originales, oriente les types d’impacts potentiels. Les choix opérés en matière d’aménagement touristique sont donc primordiaux : dans quelles conditions opte-t-on pour un tourisme balnéaire classique, massif, ou pour une approche touristique alternative ? Ces différentes déclinaisons sont-elles attachées à des territoires spécifiques ? Faut-il opposer ces deux approches ou les considérer complémentaires dans leurs environnements respectifs, peuvent-elles partager un même espace ? L’objectif de ce numéro thématique est de réunir des approches diverses et renouvelées qui développent des analyses sous l’angle de l’économie, de l’aménagement du territoire, de la sociologie, de la géographie… Les articles pourront proposer une réflexion théorique ou privilégier des études de cas, traitant des relations tourisme de masse – tourisme alternatif ou s’attachant à illustrer l’une de ces deux aspects. Les terrains privilégiés ne seront pas exclusivement caribéens et américains, ils pourront relever de n’importe quelle région du monde et illustrer des situations présentes et/ou passées. Les thématiques privilégiées seront : 1. Les concepts de tourisme de masse et de tourisme alternatif (identification, caractéristiques, logiques spatiales, enjeux économiques, sociaux, environnementaux). 2. Les lieux du tourisme masse (stations balnéaires, villes historiques, formes spécifiques d’aménagement des lieux et les types de structures d’accueil) 3. Alter-tourismes et renouvellement des pratiques touristiques (écotourisme, tourisme communautaire, agrotourisme …) 4. L’aménagement des lieux touristiques et les modalités de gestion des environnements protégés (conservation, protection et pratiques touristiques et récréatives) 5. Les enjeux économiques, sociaux, environnementaux autour de différents types de lieux touristiques. This issue of the Revue Etudes Caribéennes, devoted to tourism, aims to lay the foundations of a reflection on the functioning tourist places, their development programs and the different challenges presented to them. Exposed/Open or closed location, concentrated or diffused flows, the nature of these tourist places with their traditional or original customs, orientate different types of potential impacts. The choices made in tourism development are essential: in which conditions should be opted for the traditional seaside tourism, or for mass tourism, or for alternative tourism? Are certain properties linked to specific territories? Should we oppose these two approaches or consider them as complementary in their environments and can they share the same place? The objective of this thematic issue is to call for various and renewed approaches which develop analysis in terms of the economy, regional planning, sociology, geography etc. Articles may propose a theoretical reflection or focus on case studies, dealing with the relations of mass tourism, alternative tourism, or to illustrate one of these two aspects. Priorities fields will not exclusively be Caribbean and American but can come from any part of the world and can illustrate post and/or present situations. The prioritized analysis will include: 1. The concepts of mass tourism and alternative tourism (identification, characteristics, spatial logics, and economic, social and environmental issues). 2. Places of mass tourism (resorts, historic cities, specific forms of site layout and reception facilities) 3. Alter-tourism and the renewal of tourism practices (ecotourism, community tourism, agrotourism) 4. The development of tourist spots and of management methods concerning protected environments (conservation, protection, tourism practices and recreational practices) 5. Economic, social, and environmental issues surrounding different types of tourist places. Este número de la Revista Estudios Caribeños consagrado al turismo apunta a poner las bases de una reflexión sobre el funcionamiento de los lugares turísticos, los programas de ordenación turística y las diferentes apuestas para los territorios. Lugar abierto o cerrado, flujos concentrados o flujos difusos, la naturaleza del lugar turístico, con sus prácticas, clásicas u originales, orienta los tipos de impactos potenciales. Las elecciones operadas en materia de ordenación turística son primordiales: ¿en qué condiciones se opta por un turismo balneario clásico, masivo, o por un enfoque turístico alternativo? ¿Estas diferentes declinaciones están relacionadas a territorios específicos? ¿Se debe oponer estos dos enfoques o considerarlos complementarios en sus ambientes respectivos, pueden compartir el mismo espacio? El objetivo de este número temático es de reunir los diversos y renovados enfoques que desarrollan los análisis sobre el ángulo de la economía, la ordenación del territorio, la sociología, la geografía… Los artículos podrán proponer una reflexión teórica o privilegiar los estudios prácticos, tratando las relaciones turismo de masa-turismo alternativo o dirigirse a ilustrar uno de estos dos aspectos. Los terrenos privilegiados no serán exclusivamente caribeños y americanos, podrán hacer frente a cualquier región del mundo e ilustrar situaciones presentes y/o pasadas. Los temas privilegiados serán: 1. Los conceptos de turismo de masa y de turismo alternativo (identificación, características, lógicas espaciales, apuestas económicas, sociales, ambientales). 2. Los lugares de turismo de masa (estaciones balnearias, ciudades históricas, formas específicas de ordenación de lugares y de tipos de estructuras de recepción). 3. Alter-turismos y renovación de las prácticas turísticas (ecoturismo, turismo comunitario, agroturismo...). 4. La ordenación de lugares turísticos y las modalidades de gestión de los ambientes protegidos (conservación, protección y prácticas turísticas y recreativas). 5. Las apuestas económicas, sociales, ambientales alrededor de diferentes tipos de lugares turísticos.

Résumé : For Norwegians the name of our country is based on a route - "the way to the North" - and this was not a built route but using of the coast-line itself. As long as the boats and ships were the main means of travel this coastal way - "Nor-way" - was the main communication basis for most people, and for transport of goods. But even in the interior of the country, water, namely rivers and lakes were the main structures for communication. The lakes were most efficient for transport during the cold winters, by sledges on the frozen surfaces.When new means of transport took over most of the traffic, however, sea, lakes and rivers in many ways became obstacles instead of means of communication (?). This gave the government and others new challenges. In the sailing period up to the end of the eighteen hundreds, boats and harbors were the investment focus and sailors were recruited in every community from the age of 15. This meant that in a remote area at the Arctic Circle there were plenty of people who have been sailing around most of the work and could easily be hosts of visitors.This paper is mostly focusing on "how to market and develop these beautiful coastal areas to travelers using either their own cars, bikes, boats or collective transport". What types of geographical units are suited for marketing and developing such areas and how might local producers of accommodation, food & beverages, crafts, activities and arts be included in such organizations. The main focus will be on the work of organization "Kystriksvegen Reiseliv AS" that have been working with these challenges for closed to two decades. What have their successes and obstacles been and how have they been able to operate a sustainable business on a long coastal route with many car ferries, small islands, fjords and mountains and more than twenty municipalities.
Pour les Norvégiens, le nom de notre pays est basé sur un itinéraire - «le chemin vers le Nord» - et ce n'était pas une route construite, mais qui repose sur la ligne de côte elle-même. Tant que les bateaux et les navires étaient le principal moyen de déplacement de cette façon côtière – "Nor-way" - était la base principale de communication pour la plupart des gens et pour le transport de marchandises, et même à l'intérieur du pays, l'eau, à savoir les rivières et les lacs étaient les principales structures de communication. Les lacs sont les plus efficaces pour le transport pendant les hivers froids, par traîneaux sur les surfaces gelées.Avec l’arrivée des nouveaux moyens de transport, la mer, les lacs et les rivières à bien des égards, sont devenus obstacles (?). Cela a donné de nouveaux défis au gouvernement. A l’époque de la voile jusqu'à la fin des dix-huit centaines, des bateaux et des ports ont été l'objet d'investissements et les marins ont été recrutés dans toutes les collectivités dès l’âge de 15 ans. Cela signifie que dans une région éloignée dans le cercle arctique, il y avait beaucoup de gens qui étaient navigateurs et pouvaient facilement être les hôtes de visiteurs.Ce document est principalement axé sur «la façon de commercialiser et de développer ces belles régions côtières de voyageurs qui utilisent soit leurs propres voitures, motos, bateaux ou de transports collectifs». Quels types d'unités géographiques sont adaptés pour la commercialisation et le développement de ces régions ? Comment les producteurs locaux d'hébergement, de nourriture et de boissons, d’artisanat, les activités et les arts sont inclus dans ces organisations ? L'accent principal sera mis sur le travail de l’organisation "Reiseliv AS Kystriksvegen" qui a travaillé sur ces défis de fermeture depuis deux décennies. Quelles ont été leurs réussites et obstacles, et comment ont-ils pu exploiter une entreprise durable sur une longue route côtière avec des car-ferries, de nombreuses petites îles, des fjords et des montagnes et plus d’une vingtaine de municipalités.

Résumé : International audience
Geographical distribution of parasite species can provide insights into the evolution and diversity of parasiticcommunities. Biogeography of marine parasites is poorly known, especially because it requires anunderstanding of host-parasite interactions, information that is rare, especially over large spatial scales.Here, we have studied the biogeographical patterns of dactylogyrid parasites of chaetodontids, one of themost well-studied fish families, in the tropical Indo-west Pacific region. Dactylogyrid parasites were collectedfrom gills of 34 butterflyfish species (n = 560) at nine localities within an approximate area of62 million km2. Thirteen dactylogyrid species were identified, with richness ranging from 6 to 12 speciesat individual localities. Most dactylogyrid communities were dominated by Haliotrema angelopterum orHaliotrema aurigae, for which relative abundance was negatively correlated (q = !0.59). Parasite richnessand diversity were highest in French Polynesia and the Great Barrier Reef (Australia) and lowest in Palau.Three biogeographic regions were identified based on dactylogyrid dissimilarities: French Polynesia,characterised by the dominance of H. angelopterum, the western Pacific region dominated by H. aurigae,and Ningaloo Reef (Australia), dominated by Euryhaliotrema berenguelae. Structure of host assemblageswas the main factor explaining the dissimilarity (turnover and nestedness components of the Bray-Curtis dissimilarity and overall Bray-Curtis dissimilarity) of parasite communities between localities,while environment was only significant in the turnover of parasite communities and overall dissimilarity.Spatial structure of localities explained only 10% of the turnover of parasite communities. The interactionof the three factors (host assemblages, environment and spatial structure), however, explained the highestamounts of variance of the dactylogyrid communities, indicating a strong colinearity between the factors.Our findings show that spatial arrangement of chaetodontid dactylogyrids in the tropical Indo-westPacific is primarily characterised by the turnover of the main Haliotrema spp., which is mainly explainedby the structure of host assemblages.

Résumé : Unveiling the genetic basis of local adaptation to environmental variation is a major goal in molecular ecology. In rugged landscapes characterized by environmental mosaics, living populations and communities can experience steep ecological gradients over very short geographical distances. In lowland tropical forests, interspecific divergence in edaphic specialization (for seasonally flooded bottomlands and seasonally dry terra firme soils) has been proven by ecological studies on adaptive traits. Some species are nevertheless capable of covering the entire span of the gradient; intraspecific variation for adaptation to contrasting conditions may explain the distribution of such ecological generalists. We investigated whether local divergence happens at small spatial scales in two stands of Eperua falcata (Fabaceae), a widespread tree species of the Guiana Shield. We investigated Single Nucleotide Polymorphisms (SNP) and sequence divergence as well as spatial genetic structure (SGS) at four genes putatively involved in stress response and three genes with unknown function. Significant genetic differentiation was observed among sub-populations within stands, and eight SNP loci showed patterns compatible with disruptive selection. SGS analysis showed genetic turnover along the gradients at three loci, and at least one haplotype was found to be in repulsion with one habitat. Taken together, these results suggest genetic differentiation at small spatial scale in spite of gene flow. We hypothesize that heterogeneous environments may cause molecular divergence, possibly associated to local adaptation in E. falcata.

Résumé : International audience
We studied the monogenean communities of 34 species of butterflyfish from the tropical Indo-West Pacific, identifying 13 dactylogyrid species (including two species that are presently undescribed). Monogenean assemblages differed significantly between host species in terms of taxonomic structure, intensity and prevalence. Parasite richness ranged from 0 (Chaetodon lunulatus) to 11 (C. auriga, C. citrinellus and C. lunula). Host specificity varied between the dactylogyrids species, being found on 2-29 of the 34 chaetodontid species examined. Sympatric butterflyfish species were typically parasitized by different combinations of dactylogyrid species, suggesting the existence of complex host-parasite interactions. We identified six clusters of butterflyfish species based on the similarities of their dactylogyrid communities. Dactylogyrid richness and diversity were not related to host size, diet specialization, depth range or phylogeny of butterflyfish species. However, there was a weak positive correlation between monogenean richness and diversity and host geographical range. Most communities of dactylogyrids were dominated by Haliotrema aurigae and H. angelopterum, indicating the importance of the genus Haliotrema in shaping monogenean communities of butterflyfishes. This study casts light on the structure of the monogenean communities of butterflyfishes, suggesting that the diversity and complexity of community structures arises from a combination of host species-specific parameters.
