Description : Antarctica is a continent of enigmas. Stunning geographic beauty belies its inhospitable climate. Covered a mile thick in ice, it is the world's largest desert. Fossil ferns found in its mountains speak of its prehistory as a tropical rainforest, but now is largely devoid of life. Its most famous inhabitant, the penguin, is thought of as a flightless bird, but soars underwater much as a falcon glides the sky. Perhaps one of the greatest enigmas is the contrast between the terrestrial and marine environments. On land, monochromatic snow and ice support little life, yet the sea teams with life, life that expresses itself with the full rainbow of colors. Color is but one manifestation of chemical ecology. The Antarctic benthos supports an extensive community of predators and prey, competitors and facilitators. A harsh geographic history has contributed to marine diversification and enhanced what we now recognize as a rich flora and fauna, commensurate in some instances with temperate kelp forests and even approaching the richness of tropical marine environments. Not surprisingly, Antarctic benthic ecology is highly dependent on chemical mediation of interspecific interactions, interweaving chemodiversity with biodiversity in a classical yin and yang feedback loop. The evolution of selective chemical defenses facilitates drug discovery research, producing suites of metabolites that inform structure-activity studies and add breadth to bioactivity profiles. This presentation will focus on recent and contextual research from our lab which has demonstrated the potential for new biomedical lead molecules and scaffolds from these difficult to access biological resources.

Résumé : International audience
Diffusion parameters for HTO, 36Cl−, and 125I− were determined on Upper Toarcian argillite samples from the Tournemire Underground Research Laboratory (Aveyron, France) using the through diffusion technique. The direction of diffusion was parallel to the bedding plane. The purpose of the present study was 3-fold; it was intended (i) to confirm the I− interaction with Upper Toarcian argillite and to verify the effects of initial I− concentration on this affinity, as previously observed by means of radial diffusion experiments, (ii) to highlight any discrepancy between Cl− and I− diffusivity, and (iii) to investigate the effect of an increase of the ionic strength of the solution on the anionic tracers' diffusive behaviour. The results show that the effective diffusion coefficient (De) and diffusion accessible porosity (εa) values obtained with an ionic strength (I.S.) synthetic pore water of 0.01 eq L−1 are: De = 2.35-2.50 × 10−11 m2 s−1 and εa = 12.0-15.0% for HTO, and De = 14.5-15.5 × 10−13 m2 s−1 and εa = 2.5-2.9% for 36Cl−. Because of anionic exclusion effects, anions diffuse slower and exhibit smaller diffusion accessible porosities than HTO, taken as a water tracer. The associated effective diffusion coefficient (De) and rock capacity factor (α) obtained for 125I are: De = 7.00-8.60 × 10−13 m2 s−1 and α = 4.3-7.2%. Such values make it possible to calculate low 125I distribution ratios (0.0057 < RD < 0.0192 mL g−1) which confirm the trend indicating that the 125I rock capacity factor increases with the decrease of the initial I− concentration. Additional through-diffusion experiments were carried out with a higher ionic strength synthetic pore water (I.S. = 0.11 eq L−1). No evolution of HTO diffusion parameters was observed. The anionic tracers' effective diffusion coefficient increased by a factor of two but no clear evolution of their accessible porosity was observed. Such a paradox could be related to the particularly small mean pore size of the Upper Toarcian argillite of Tournemire. The most significant finding of this study is the large discrepancy (factor of two) between the values of the effective diffusion coefficient for 125I and 36Cl. Whatever the ionic strength of the synthetic solution used, 125I exhibited De values two times lower than those of 36Cl. A detailed explanation for this difference cannot be given at present even if a hypothesis based on ion-pairing or on steric-exclusion cannot be excluded. This makes questionable the assumption usually made for quantifying 125I sorption and postulating that 36Cl and 125I would diffuse in the same porosity. In other terms, at Tournemire, 125I sorption could be more pronounced than previously indicated.

Résumé : International audience
Within thirty years, the small island of Saint-Barthelemy (25 km²) is out of its secular isolation to be among major luxury tourism destinations in the world. In this study, the idea is to identify structural element and different cyclical factors that help to understand Saint-Barthelemy tourism situation. The small size of the territory itself can be seen as a fundamental handicap or, conversely, as a considerable asset. Everything depends on development project. It is necessary to know how to take advantage of specific characteristics of this type of territory. In Saint-Barthelemy case, scarcity is coveted; this coveted rarity is accessible only for rich people. The coveted rarity leads to luxury. Isolation is relative: this destination is not accessible to the jumbo jets. The airline market is controlled essentially by two small local companies and the airspace is open to charter flies and private aircrafts. Some other companies provide more or less regular flights from nearby airports of San Juan (Puerto Rico), Sint-Maarten and Guadeloupe. Luxury cannot be decreed, it is not planned. Luxury tourism is the election of a territory by elites who gather there to enjoy away from the rest of the world.
En l’espace de trente ans, la petite île de Saint-Barthélemy (25 km²) est sortie de son isolement séculaire pour s’imposer parmi les grandes destinations du tourisme de luxe dans le monde. Dans le cadre de cette étude, l’idée est d’identifier les éléments structurels et les différents facteurs conjoncturels qui permettent de comprendre la situation touristique de Saint-Barthélemy. L’exiguïté du territoire en lui-même peut être perçue comme un handicap fondamental ou, inversement, comme un atout considérable. Tout dépend du projet de développement. Il faut savoir tirer profit des spécificités du territoire considéré. Dans le cas de Saint-Barthélemy, l’exiguïté favorise la rareté et cette rareté convoitée n’est accessible qu’aux personnes les plus argentées. La rareté convoitée conduit au luxe. L’isolement est relatif : cette destination n’est pas accessible aux avions gros porteurs, l’essentiel du marché aérien est contrôlé par deux petites compagnies locales et l’espace aérien est ouvert aux petits avions privés. Le luxe ne se décrète pas, il ne se planifie pas. Le tourisme de luxe, c’est l’élection d’un territoire par des élites qui s’y retrouvent pour jouir de leur fortune à l’écart du monde.

Résumé : Les pouvoirs publics doivent faire face à la pollution des sols et des ressources en eau, par un pesticide organochloré (la chlordécone). La forte rétention de ce pesticide dans les sols volcaniques et la microstructure peu accessible des allophanes conduit au constat qu'il sera difficile de dépolluer les sols par des techniques classiques (chimiques, phytoremédiation ou biodégradation) déjà peu adaptée à cette molécule persistante. Nous proposons donc une alternative à la dépollution : la séquestration des pesticides. L'objectif est de favoriser le piégeage des pesticides dans le sol en incorporant de la matière organique (MO). Les résultats obtenus démontrent l'efficacité du procédé avec des transferts sol/eau et sol/plantes fortement diminués grâce à l'ajout de MO.
