Résumé : International audience
In the past the Caribbean was restricted to offering elitist tourist activities, but over the last three decades it has to a large extent opened its doors to international tourism. The advent of mass tourism has been accompanied by a redistribution of the tourism functions and flows within the region. The significant growth in tourism, although essential to the economies of the Caribbean islands, has given rise to a number of issues, the first being the necessity to examine the multiplier effect from tourism revenue within these externally-dependent economies. Next there is both the question of access to resources and the closing of tourist sites in a context where local communities are focusing on coastlines to develop their own numerous tourism and recreational activities. These developments will inevitably require us to consider environmental issues and the sustainability of today’s predominant tourism activities.
Longtemps limité à des pratiques touristiques élitistes, l’espace caribéen s’est largement ouvert au tourisme international au cours des trois dernières décennies. L’avènement du tourisme de masse s’est accompagné d’une redistribution des flux et de fonctions touristiques dans cette région. Les enjeux, qui accompagnent l’importance croissante du fait touristique, essentiel pour les économies des îles caribéennes, sont de plusieurs ordres : tout d’abord, il convient de s’interroger sur les effets d’entraînement des revenus du tourisme dans le cadre de ces économies extraverties. Se pose également la question de l’accès aux ressources et de la fermeture des lieux touristiques, dans un contexte où les sociétés locales développent aussi leurs propres pratiques touristiques et récréatives ; autant d’usages qui se polarisent sur des ressources littorales et doivent nous interpeller sur les enjeux environnementaux et la durabilité des pratiques touristiques qui prévalent aujourd’hui.

Résumé : International audience
This study constitutes one of the few works conducted on the colonization of recent lava flows by fish communities in coral reef environment. It attempted to describe the mechanisms of colonization and environmental variables infuencing the structure of communities on the lava flows of the Piton de la Fournaise volcano at Reunion Island. It also proposed some hypotheses on the mechanisms of selection and speciation of endemic species of thesouthwestern Indian Ocean region, particularly diversified on the most recent lava flows of the Piton de la Fournaise, and provided a model of distribution of environmental and fish assemblage variables in four homogeneous patterns of colonization (landscapes) retained within the study area. The results showed fish community structure strongly related to measured environmental variables, of which depth, width of the island shelf, age of the lava flow and distance to the most recent lava flow were the most influential. It also appeared that the maximum endemic species richness was measured on the shallower stations, with narrow insular shelf, located on recent lava flows, near the lava flow from the eruption of 2007 (latest volcanic event). These characteristics define a harsh environment, to which endemic species seem well-adapted due in particular to their strong demographic and dietary flexibility. Finally, the patterns of colonization were characterized by significantly different environmental variables. The four homogeneous areas, defined by two geomorphological features, basalt blocks and drop-offs, nested within two locations, inside and outside the volcanic enclosure (current caldera), hosted fish communities whose dominant diets mainly depend on the nature, the abundance and the accessibility of available food resources. Overall, the study highlights that during early stages of ecological succession, site selection by fish communities is highly dependent on environmental constraints, specially of volcanic origin, but the physical habitat selection (geomorphology, substrate rugosity, percentage of soft substrate) seems to have littleimportance, while at least on the trophic structure and the distribution of endemic species.
