Résumé : Cette étude souligne l’importance des enjeux touristiques pour les îles tropicales. La singularité des espaces est trop souvent négligée en raison de la vigueur des représentations fantasmées de l’île tropicale qui est perçue tel un lieu paradisiaque, un lieu d’accomplissement de désirs illimités où s’écoule une vie facile, avec ses rivages ensoleillés, entre récifs coralliens et plages de sable blanc bordées de cocotiers. Ces richesses immatérielles reposent sur des ressources bien réelles, abondantes et vulnérables, à l’image des emblématiques récifs coralliens. Certes les destinations insulaires tropicales ne connaissent pas les niveaux de fréquentation des grandes régions du monde, mais leurs flux doivent être reconsidérés au regard des caractéristiques de ces territoires (faible superficie, charge de population, rareté de la terre, limites des ressources) qui nécessitent la définition d’indications spécifiques. Mais l’avènement d’un tourisme de masse dans ces ultimes frontières, ces « Pleasure Periphery » nécessite de s’interroger sur la viabilité des stratégies de développement mises en œuvre autour du tourisme.
This study highlights the importance of tourism issues for the tropical islands. The singularity of the spaces is too often overlooked because of the strength of fantasized representations of the tropical island which is seen as a paradise, a place of accomplishment desires unlimited with an easy life, with its sunny shores, between coral reefs and white sandy beaches lined with coconut trees. These intangible wealth are based on real resources, abundant and vulnerable, like the emblematic image of coral reefs. Although the tropical island destinations are not supported the weight of the major touristic regions of the world but their flows should be reconsidered in the light of the characteristics of these territories (small size, load population, shortage of land, limits of resources) that require defining specific indicators. But the advent of mass tourism in these last frontiers, these "Pleasure Periphery" needs to question the sustainability of tourism development strategies.

Résumé : National audience
The late Lower to Middle Permian Panjal Traps (NW Himalaya, India-Pakistan) represent the greatest magmatic province erupted on the northern Indian platform during the Neotethys opening. New geochemical and isotopic analyses were performed on basalts from the eastern borders of the traps (SE Zanskar-NW Spiti area) in order to characterize this volcanism, to discuss its compositional variations in comparison to Panjal counterparts and its relationships with the opening of Neotethys. Lavas show features of tholeiitic low-Ti (< 1.6%) continental flood basalts with LREE, Th enrichments and Nb-Ta negative anomalies. Trace element ratios combined with {varepsilon}Ndi values (–3.6 to +0.9) and high Pb isotopic ratios suggest that these tholeiitic basalts were derived from an OIB-like mantle contaminated at various degrees by a continental crust component. Previous geochemical features are broadly similar to those of the coeval Panjal volcanic sequences identified westwards (Ladakh, Kashmir and Pakistan). Present geochemical constraints obtained for the Panjal Traps basalts suggest they originated from rapid effusion of tholeiitic melts during opening of the Neotethys Ocean. Similar magmatism implying an OIB-type reservoir is contemporaneously recognized on and along the adjacent Arabian platform. Both Indian and Arabian Permian volcanics were emplaced during coeval syn-rift to post rift transition. These Lower to Middle Permian south Neotethyan continental flood magmatism are regarded as associated to a passive rifting. In this scheme, OIB-type isotopic signature would be related either to a melting episode of syn-rift up-welling mantle plumes or to a melting of a regional abnormally hot and enriched mantle.

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 rapid development of the albacore tuna (Thunnus alalunga) driftnet fishery in the Pay of Biscay (Atlantic ocean, France) has incited European management authorities to ask for a study of its ecological impact on populations of common dolphins and striped dolphins. A programme with onboard observers has been led during 1992 and 1993, and a sighting survey has allowed the evaluation of the abundances of fractions of populations in the studied area. For the population of common dolphins, the biological parameter estimation has allowed the building of a discrete age-structured model based on a Leslie matrix. Sensitivity studies have been conducted using four model parameters (age of first reproduction, interval between births, juvenile and adult survival rates). Results show that the increase rate of the population presents the highest sensitivity versus adult survival rate and, in second place versus the interval between births.
Le développement rapide de la pêche au thon germon (Thunnus alalunga) au filet maillant dérivant dans le golfe de Gascogne a incité les instances de gestion européenne à demander une étude de son impact écologique sur les populations de dauphin commun et de dauphin bleu et blanc. Des observateurs embarqués à bord ont mené au cours des années 1992 et 1993 une campagne d'échantillonnage sur un parcours linéaire, ce qui a permis d'estimer l'abondance des fractions de populations présentes sur la zone étudiée. Pour la population de dauphins communs, l'estimation des paramètres biologiques a permis de construire un modèle à pas discret structuré en âge faisant appel à une matrice de Leslie. Des études de sensibilité ont été réalisées selon quatre paramètres du modèle; âge de première mise bas, intervalle entre mises bas, taux de survie des juvéniles, taux de survie des adultes sur les deux sexes confondus. Les résultats montrent que le taux d'accroissement de la population présente la plus forte sensibilité, en fonction du taux de survie des adultes avec, en deuxième ordre, l'intervalle entre mises bas.

Résumé : International audience
The Lanzo peridotite massif is a fragment of oceanic lithosphere generated in an ocean-continent transition context and eclogitized during alpine collision. Despite the subduction history, the massif has preserved its sedimentary oceanic cover, suggesting that it may have preserved its oceanic structure. It is an exceptional case for studying the evolution of a fragment of the lithosphere from its oceanization to its subduction and then exhumation. We present a field and petrological study retracing the different serpentinization episodes and their impact on the massif structure. The Lanzo massif is composed of slightly serpentinized peridotites (<20% serpentinization) surrounded by an envelope of foliated serpentinites (100% serpentinization) bordered by oceanic metabasalts and metasedimentary rocks. The limit between peridotites and serpentinites defines the front of serpentinization. This limit is sharp: it is marked by the presence of massive serpentinites (80% serpentinization) and, locally, by dykes of metagabbros and mylonitic gabbros. The deformation of these gabbros is contemporaneous with the emplacement of the magma. The presence of early lizardite in the peridotites testifies that serpentinization began during the oceanization, which is confirmed by the presence of meta-ophicarbonates bordering the foliated serpentinite envelope. Two additional generations of serpentine occur in the ultramafic rocks. The first is a prograde antigorite that partially replaced the lizardite and the relict primary minerals of the peridotite during subduction, indicating that serpentinization is an active process at the ridge and in the subduction zone. Locally, this episode is followed by the deserpentinization of antigorite at peak P-T (estimated in eclogitized metagabbros at 2-2.5 GPa and 550-620 °C): it is marked by the crystallization of secondary olivine associated with chlorite and/or antigorite and of clinopyroxene, amphibole and chlorite assemblages. A second antigorite formed during exhumation partially to completely obliterating previous textures in the massive and foliated serpentinites. Serpentinites are an important component of the oceanic lithosphere generated in slow to ultraslow spreading settings, and in these settings, there is a serpentinization gradient with depth in the upper mantle. The seismic Moho limit could correspond to a serpentinization front affecting the mantle. This partially serpentinized zone constitutes a less competent level where, during subduction and exhumation, deformation and fluid circulation are localized. In this zone, the reaction kinetics are increased and the later steps of serpentinization obliterate the evidence of this progressive zone of serpentinization. In the Lanzo massif, this zone fully recrystallized into serpentinite during alpine subduction and collision. Thus, the serpentinite envelope represents the oceanic crust as defined by geophysicists, and the sharp front of serpentinization corresponds to an eclogitized seismic palaeo-Moho.

Résumé : International audience
The Longmen Shan range is one of the major topographic and structural features of the easternmargin of the Tibetan Plateau. With an impressive topographic gradient and low convergence rates across the range this region has raised important questions concerning the dynamics of plateaumargin settings, such as the long-term mechanisms of topographic evolution. The investigation of the distribution in space and time of denudation can provide critical insight into such dynamics and shed light on still unresolved controversies. For that purpose, we present a new dataset that documents the intensity and distribution of denudation processes across this plateaumargin through field survey of fluvial incision markers, quantitative geomorphology and cosmogenic nuclide derived basin-wide erosion rates. Erosion is < 0.5 mm/year in the frontal region of the Longmen Shan and between 0.5 and 1 mm/year further west, with a gradual decrease when reaching the northern headwaters of the Min Jiang watershed, adjacent to the beginning of the Tibetan Plateau. The spatialdistribution of denudation inferred from the various methods we use suggests that most of the differential uplift in the Central Longmen Shan is accommodated by the Beichuan Fault and frontal structures located in the foothills. The denudation pattern seems also to reflect the large-scale propagation of erosion from the Sichuan Basin toward the Plateau. This suggests that the Longmen Shan range is submitted to the combined influences of slow thrusting activity on the frontal structures and progressive westward regressiveerosion as a probable response to a pulse of uplift of the Tibetan PlateauEasternmargin, that started 10 Ma ago.

Résumé : International audience
Loin d’apparaître comme de simples interfaces, les littoraux de la Caraïbe sont constituésd’enclaves fonctionnelles qui se juxtaposent donnant une mosaïque créole polyéthnique(mosaïque raciale), aux fractures sociales et spatiales marquées (mosaïque sociale et spatiale).Dans ces îles paysannes qui traditionnellement tournent le dos à la mer, la plage a longtempsété perçue par les populations littorales et les pêcheurs comme une continuité de l’île de laplantation pour y habiter et y pêcher. Une marge ouverte à tous dont la population rurale seméfiait pour ne l’aborder que quelques heures dans l’année à Pâques ou à la Pentecôte.2 Tout au long du XX siècle, une véritable subversion du regard s’opère par les classesdominantes, bourgeoises et touristes qui investissent les plages, souvent celles qui n’étaientguère fréquentées. Quitter la plage peu à peu investie par les touristes pour les fonds blancsou la Baignoire de Joséphine constitue une nouvelle marque, une volonté de maintenir unehiérarchie sociale par la distance.3 Depuis quelques années, les plages deviennent des lieux d’hybridation entre les populationslocales et les touristes. Avec la tertiairisation des sociétés, les populations antillaises desclasses moyennes et défavorisées découvrent les plages qui occupent une place importantedans la culture (publicité, télé…) des jeunes générations. Les plages sont investies etdeviennent peu à peu des espaces conviviaux.4 La ségrégation sociospatiale demeure cependant dans les pratiques, les temps et même lesespaces occupés. Si certains îlets et fonds blancs, comme les plages s’ouvrent au plus grandnombre, la piscine privée, le yacht, l’îlet privé, l’enclave protégée permettent toujours deconserver distance et discrétion. De même la capacité financière nécessaire à la pratique decertains sports nautiques permet cette démarcation. Ainsi, touristes, Métropolitains et Antillaisdes classes moyennes ou appartenant à la bourgeoisie, se côtoient et se croisent mais nepratiquent pas forcément la même plage.

Résumé : International audience
BACKGROUND: People in developed countries are widely exposed to low levels of organochlorine pesticides, polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs). Seafood is a major contributor to PCB exposure. Toxicity of those various pollutants to reproductive and endocrine functions raises questions about possible effects on fertility. We explored whether serum levels of these pollutants and seafood consumption were associated with the fertility of couples enrolled in a French birth cohort (PELAGIE). METHODS: Time-to-pregnancy was investigated in 3,421 pregnant women by asking how many months they had taken to conceive. Levels of 14 organochlorine pesticides, 12 PCBs, and 10 PBDE compounds were measured in cord blood serum from a random subcohort (n = 394). Mercury concentrations measured in maternal hair were considered as a potential coexposure. Fecundability odds ratios (ORs) were estimated from multivariate discrete-time Cox proportional hazard models. RESULTS: Shellfish consumption was associated with longer time-to-pregnancy (fecundability OR ≥twice/week vs. 0.410 µg/L vs. <0.266 µg/L, fecundability OR = 0.46 [0.32-0.66]). In multiple sensitivity analyses, reduced fecundability was most consistently associated with shellfish consumption, p,p'-DDE, total PCBs, PCB153, and PCB187. Models that simultaneously included multiple coexposure factors led to similar conclusions. CONCLUSIONS: Our findings were robust in sensitivity analyses, including analysis restricted to primiparous women. These results suggest that PCBs, p,p'-DDE, and other shellfish contaminants may impair human fertility.

Résumé : We investigated the relationship between habitat association and physiological performance in four congeneric species pairs exhibiting contrasting distributions between seasonally flooded and terra firme habitats in lowland tropical rain forests of French Guiana, including Virola and Iryanthera (Myristicaceae), Symphonia (Clusiaceae), and Eperua (Caesalpiniaceae). We analyzed 10-year data sets of mapped and measured saplings (stems 150 cm in height and <10 cm diameter at breast height [dbh]) and trees (stems 10 cm dbh) across 37.5 ha of permanent plots covering a 300-ha zone, within which seasonally flooded areas (where the water table never descends below 1 m) have been mapped. Additionally, we tested the response of growth, survival, and leaf functional traits of these species to drought and flood stress in a controlled experiment. We tested for habitat preference using a modification of the torus translation method. Strong contrasting associations of the species pairs of Iryanthera, Virola, and Symphonia were observed at the sapling stage, and these associations strengthened for the tree stage. Neither species of Eperua was significantly associated with flooded habitats at the sapling stage, but E. falcata was significantly and positively associated with flooded forests at the tree stage, and trees of E. grandiflora were found almost exclusively in nonflooded habitats. Differential performance provided limited explanatory support for the observed habitat associations, with only congeners of Iryanthera exhibiting divergent sapling survival and tree growth. Seedlings of species associated with flooded forest tended to have higher photosynthetic capacity than their congeners at field capacity. In addition, they tended to have the largest reductions in leaf gas exchange and growth rate in response to experimental drought stress and the least reductions in response to experimental inundation. The corroboration of habitat association with differences in functional traits and, to a lesser extent, measures of performance provides an explanation for the regional coexistence of these species pairs. We suggest that specialization to seasonally flooded habitats may explain patterns of adaptive radiation in many tropical tree genera and thereby provide a substantial contribution to regional tree diversity.
