Résumé : L’aquaculture de crevettes Litopeneus stylirostris, qui est apparue en 1970 en Nouvelle-Calédonie, est devenue une activité économique importante aujourd’hui avec 17 fermes en production et un tonnage de 2000 tonnes en 2004. Situées sur des zones d’arrière mangrove, les fermes exercent une pression sur l’environnement limitrophe, notamment les mangroves. Le rejet des eaux usées des fermes aquacoles dans le lagon semble constituer le principal impact sur l’environnement côtier. La présente étude qui a été lancée dans le cadre du programme ZoNéCo a pour principal objectif l’évaluation d’éventuels impacts de l’aquaculture sur les mangroves de Nouvelle-Calédonie. Elle s’attache : - d’une part à étudier l’évolution des différentes strates végétales d’une mangrove en terme de structure et de superficie par le biais d’analyses diachroniques de photographies aériennes de 3 sites (2 sites jouxtant des fermes aquacoles aux caractéristiques différentes et 1 site vierge) ; - d’autre part à analyser in situ quelques paramètres physico-chimiques (pH, potentiel d’oxydo-réduction, concentrations d’azote et de phosphore totaux dans l’eau, le sédiment et les feuilles de palétuviers) et biologiques (richesse spécifique et densité des organismes mégabenthiques du sédiment à proximité des bassins) sur ces trois sites et voir dans quelle mesure ils peuvent être utilisés comme indicateurs d’impacts. L’analyse diachronique des photographies aériennes depuis 1954 jusqu’en 2004 a mis en évidence sur les sites proches de fermes aquacoles une progression et une densification des palétuviers Rhizophora vers l’intérieur des terres. Cette évolution qui était minime avant construction des fermes est plus marquée depuis. En revanche, peu de changements ont été observés sur le site vierge. Parallèlement, un développement de zones envasées et l’apparition de trouées ont été observés sur les sites exploités depuis l’établissement des fermes. La description de la végétation et les mesures des paramètres physico-chimiques montrent des différences significatives entre sites et au sein même d’un site. La pertinence des méthodologies et l’interprétation des variations intra et inter sites sont discutées. Le faible nombre d’observations ne nous permet pas d’attribuer les variations à un éventuel impact de l’aquaculture. D’autres études seront nécessaires pour valider ces résultats.

Résumé : The Momareto cruise was held from August 6 to September 6, 2006 on the new French oceanographic vessel Pourquoi pas? The ROV Victor 6000 visited three vent fields, ranging from 850m to 2300m, on the Mid-Atlantic Ridge. The scientific objective of the cruise was to study the spatial and temporal dynamics of hydrothermal communities colonizing these active vent sites. Aside scientific and technological objectives, one of the major goals of this cruise was to share the excitement of our science with the public. For this, the results of the project were shared through different media. The most challenging and exciting communication event remains the real-time transmission of images acquired by the ROV Victor at 1700m depth to a 250 person audience on land.

Résumé : International audience
Obligately epizoic diatoms (Bacillariophyta) on vertebrates were first described from cetaceans, but turtles, both freshwater and marine, also host very specific floras. Several scrapings of juvenile Chelonia mydas have allowed the description of two new diatom taxa whose valves are asymmetrical about the transapical axis, Tripterion societatis sp. nov. and Chelonicola caribeana sp. nov. These taxa are very small and show some morphological plasticity. Such plasticity might suggest their inclusion in genera with slightly different characteristics from Tripterion and Chelonicola as originally delimited. Based on our observations, an emended diagnosis is proposed for Chelonicola.

Résumé : We investigated performance trade-offs among seedlings of nine tropical tree species during a five-year field experiment. Seedlings were grown in eight microhabitat types composed of paired gap and shaded understory sites in each of four soil types. We defined performance trade-offs relevant to coexistence as significant pairwise rank reversals for species performance between contrasting situations, of which we characterize three types: microhabitat, fitness component, and ontogenetic. Only 2 of 36 species pairs exhibited microhabitat trade-offs or reversed rankings for survival or relative growth rate (RGR) among microhabitats, and only one species pair reversed performance ranks among soil types. We found stronger evidence for rank reversals between fitness components (survival and RGR), particularly in gap vs. understory environments, suggesting a general trade-off between shade tolerance (survival in shade) and gap establishment (RGR in gaps). Third, the most frequent rank reversals between species pairs occurred between early and later ontogenetic stages, especially between fitness components in contrasting microhabitats. Overall, 15 of 36 pairs of potentially competing species exhibited some type of seedling performance trade-off, two species pairs never outperformed one another, and for 19 species pairs one species was a consistent better performer. We suggest that ontogenetic trade-offs, in concert with microhabitat and fitness component trade-offs, may contribute to species coexistence of long-lived organisms such as tropical trees.

Résumé : Both short-term and long-term morphodynamics of sand barrier systems forced by moderate storm conditions have been studied significantly in the literature. However, the dynamics of the emerged beach -- from a seaside water depth of ~ 1.5 metres below the lowest tide to the back-barrier -- impacted by typhoons remain scarcely documented. This study focuses on the analysis and a better understanding of the morphologic changes of such an emerged beach, when it is forced by one typhoon, several typhoons or the combination of a summer season of typhoons and a winter season of Monsoon wave/ wind conditions. The monitoring of near-shore hydrodynamics and beach morphodynamics was performed in the Wan-Tzu-Liao sand barrier from November 2011 to August 2012. Waves, currents and water level were measured at an offshore buoy (Cigu buoy; 18 m of water depth; 1.5 km seaward the studied zone), a current profiler (4 m of water depth), and a serie of pressure sensors deployed along a cross-shore section from the lower intertidal zone up to the eolian dune. Tide was obtained from a tide gauge inside the lagoon and wind conditions were obtained respectively from an inland station and the offshore Cigu buoy. Morphodynamic changes were monitoring thanks to DGDPS surveys performed on a grid including a 300 meters long portion of sand barrier extending from the subtidal zone to the back-barrier, as well as along two cross-shore and two long-shore profiles located within the grid. Surveys were performed each week during winter and just before and after each storm during the typhoons summer season. This field methodology provided a new and very robust dataset in order to quantify sand barrier dynamics exposed to high-energy events at various time scales. Amongst the eight typhoons recorded, TALIM is the most significant and representative. Offshore wave height reached 10.34 m (Tp = 14.6 s) at Cigu buoy and 2.3 m in 4 m of water depth. Morphological changes recorded 6 m of retreat for the dune front, a 20 m large dune breaching and the occurence of a wash-over fan in the lagoon. These changes form a well-known morphodynamic responses to moderate storms. More surprisingly, TALIM drove a significant nourishment of the supratidal zone, as well as a positive sand balance on the whole sand barrier. Five other typhoons resulted in the same type of morphological responses while two typhoons resulted in a strong erosion of the whole emerged beach. During winter and spring (moderate wave conditions and strong Monsoon winds), sand moved from the beach front to the back-barrier. For the whole year, the sand barrier recorded a 12 m landward migration concomitantly with a 12 m widening without abrasion of the dune elevation.
