Résumé : In the framework of French-Brazil co-operation, the French Institute of research for exploitation of the sea (IFREMER), the State of Bahia and the company Littoral Sul Maricultura have developed a new technique for shrimp farming (Penaeus vannamei) using floating cages. After trials carried out during three years, this technique turns out very interesting from several viewpoints. The growth speed and the survival rate are very good, the negative effects on the environmental quality are weak and local fishermen have proved eager to adopt this technique as a part-time activity. In the same time, a technico-economic analysis, using a computerised simulation tool, as well as a market analysis in the State of Bahia have been carried out in order to assess the feasibility of such a project and to help research and development decisions. Despite low first investment and good biological results, the ex-farm production cost of shrimps weighing 15 g is as high as 4,5 US$ per kilo. This price is due to the low productivity of the labour and to the cost of nets which have a short life-time. It is possible to consider this activity as profitable on the market of Salvador de Bahia. Nevertheless, the question is how to face the international competition, which is particularly strong in the case of tropical shrimps. The conditions allowing enterprises to develop a strategy based on product quality and environmentally friendliness are reviewed. [NOT CONTROLLED OCR]
Dans le cadre de la coopération Franco-Brésilienne, l'IFREMER, l'Etat de Bahia et la société Littoral Sul Maricultura ont développé une nouvelle technique d'élevage de crevettes pénéides (Penaeus vannamei) en utilisant des cages flottantes. Après trois années de mise au point, cette technique s'est avérée intéressante sur plusieurs aspects. La vitesse de croissance et le taux de survie sont très satisfaisants, les effets négatifs sur la qualité du milieu naturel sont faibles et les pêcheurs locaux ont accueilli favorablement cette nouvelle pratique en complément de leur activité traditionnelle. Parallèlement, une analyse technico-économique utilisant un outil de simulation informatique ainsi qu'une analyse du marché de la crevette dans l'état de Bahia ont été conduites afin d'évaluer la faisabilité d'un tel projet et d'orienter les actions de recherche et développement. En dépit d'investissements initiaux plus faibles que dans les élevages en bassins et de bonnes performances zootechniques, le coût de production de crevettes de 15 g atteint 4,7 US$ par kilo. Dans les conditions de marché de l'Etat de Bahia, la rentabilité d'un projet d'élevage de crevettes en cage serait assurée, mais la faible productivité du travail et le coût de remplacement des filets ne permettent pas d'avoir des coûts de production aussi bas que dans les élevages en bassins. C'est pourquoi la question se pose de la possibilité pour ce type de production innovante d'affronter une concurrence internationale très forte comme dans le cas des crevettes tropicales. En particulier, les conditions dans lesquelles les entreprises peuvent développer une stratégie de compétitivité basée sur la qualité de leurs produits et sur le respect de l'environnement sont analysées.

Résumé : Tampa had no existing philanthropic or charitable institutions at the beginning of this immigration wave and, in comparison to other communities, religious institutions played a relatively modest role there. El Centro Español was founded by the Spanish elite who dominated Ybor City, to preserve their identity, provide recreational opportunities and to offer low-cost health care for the many single men and the increasing number of families settling in the area. The club's Sanatorio, completed in 1906, was probably the most modern and complete hospital in Florida at the time.

Résumé : International audience
The maintenance in the long run of a positive carbon balance under very low irradiance is a prerequisite for survival of tree seedlings below the canopy or in small gaps in a tropical rainforest. To provide a quantitative basis for this assumption, experiments were carried out to determine whether construction cost (CC) and payback time for leaves and support structures, as well as leaf life span (i) differ among species and (ii) display an irradiance-elicited plasticity. Experiments were also conducted to determine whether leaf life span correlates to CC and payback time and is close to the optimal longevity derived from an optimization model. Saplings from 13 tropical tree species were grown under three levels of irradiance. Specific-CC was computed, as well as CC scaled to leaf area at the metamer level. Photosynthesis was recorded over the leaf life span. Payback time was derived from CC and a simple photosynthesis model. Specific-CC displayed only little interspecific variability and irradiance-elicited plasticity, in contrast to CC scaled to leaf area. Leaf life span ranged from 4 months to >26 months among species, and was longest in seedlings grown under lowest irradiance. It was always much longer than payback time, even under the lowest irradiance. Leaves were shed when their photosynthesis had reached very low values, in contrast to what was predicted by an optimality model. The species ranking for the different traits was stable across irradiance treatments. The two pioneer species always displayed the smallest CC, leaf life span, and payback time. All species displayed a similar large irradiance-elicited plasticity.

Résumé : International audience
In order to study the acclimatization process over 14 days of exposure to tropical climate, 9 triathletes performed 4 outdoor indirect continuous multistage tests in both thermoneutral and tropical conditions. The thermoneutral test (TN, 14 C, 45% rh) was performed before traveling to the tropical area (Martinique, FWI). The tropical tests were performed 2, 8, and 14 days after arrival (32.9 C, 78% rh). During each trial, we measured tympanic temperature, sweat rate, body mass loss, heart rate (HR), and performance. The results showed that 1) the mean tympanic temperature was greater in T2 (P < .001), T8 (P < .01) and T14 (P < .01) than in TN and significantly lower in T14 than in T2 (P < .05); 2) the mean sweat rate was significantly greater (P < .001) in T2, T8 and T14 than in TN and significantly greater (P < .05) in T8 and T14 than in T2; 3) the body mass loss after trials was significantly greater (P < .001) in T2, T8 and T14 than in TN and significantly greater (P < .05) in T8 and T14 than in T2; 4) the mean HR and HR at rest were significantly higher (P < .005) in T2 than in TN, T8, T14 and the mean HR was significantly lower (P < .05) in T14 than in the other trials; and 5) the performance time was significantly lower in T2 (P < 0.02), T8 (P < 0.03) and T14 (P < 0.05) than in TN. We concluded that 14 days of exposure.

Résumé : International audience
STUDY OBJECTIVE: There is no consensus about the management of large spontaneous pneumothoraces. Guidelines recommend either needle aspiration or chest tube drainage and most patients are hospitalized. We assess the efficiency of ambulatory management of large spontaneous pneumothoraces with pigtail catheters. METHODS: From February 2007 to January 2011, all primary and secondary large spontaneous pneumothoraces from Lorient's hospital (France) were managed with pigtail catheters with a 1-way valve. The patients were discharged immediately and then evaluated every 2 days according to a specific algorithm. RESULTS: Of the 132 consecutive patients (110 primary, 22 secondary), 103 were exclusively managed as outpatients, with full resolution of the pneumothorax by day 2 or 4, which represents an ambulatory success rate of 78%. Mean time (SD) of drainage was 3.4 days (1.8). Seven patients were initially hospitalized but quickly discharged and had full resolution by day 2 or 4, leading to a total success rate of 83%. The use of analgesics was low. The 1-year recurrence rate was 26%. If successful, this outpatient management is potentially cost saving, with a mean cost of 926, assuming up to 2 outpatient visits and 1 chest radiograph, compared with 4,276 if a chest tube was placed and the patient was admitted to the hospital for 4 days. CONCLUSION: Ambulatory management with pigtail catheters with 1-way valves could be a reasonable first-line of treatment for large spontaneous pneumothoraces. Compared with that of other studies, our protocol does not require hospitalization and is cost saving.

Résumé : From 1972, when Solomon Taiyo Limited (stl) started a pole-and-line fishing operation, to 1980, stl vessels had been catching tuna almost exclusively from surface free-swimming schools. In 1981, a fad programme group purse-seining fishing operation, using the Filipino "payao" model, was put in place. Results were excellent and STL vessels quickly adapted their fishing methods to make the best use of fads. STL slightly modified the original payao design to better suit its own needs and nowadays, about 90% of the group purse seine catch, i.e. 5,800 t annually, and around 60-70% of the pole-and-line catch, i.e. about 15,000 t annually, come from fad fishing. fads bring benefits not only to stl but also to the rural communities of the region. For stl, it allows savings on the operational costs, especially those of pole-and-line fishing operations, reduction of searching time and a better regularity of fish landings. For the rural communities, it gives better returns to bait-ground owners through royalties paid by stl for their baitfishing boats and it allows local fishing communities (known as canoe-fishermen) to increase their catches using fishing methods (artisanal) such as trolling and midwater handlines set around fads. This provides fish for family consumption and a source of income from fish sold. Overall, the importance of fads to stl's fishing operation, and therefore to the local economy as a whole, is high, although no precise value can be attached to it.

Résumé : International audience
In this paper we present a new local remeshing algorithm that is dedicated to the problem of erosion in finite element models whose grid follows the movement of the free surface. The method, which we name Surface Lagrangian Remeshing (SLR), is adapted to 2D Lagrangian models which couple surface erosion with deformation of Earth materials. The remeshing procedure preserves nodes defining the surface submitted to erosion and removes nodes belonging to surface elements whose internal angles or area is critically low. This algorithm is ideally suited to track long term surface evolution. To validate the method we perform a set of numerical tests, using triangular finite elements, which compare the results obtained with the SLR algorithm with global remeshing and with analytical results. The results show good agreements with analytical solutions. Interpolation errors associated with remeshing are generated locally and numerical diffusion is restricted to the remeshed domain itself. In addition this method is computationally costless compared to classical global remeshing algorithm. We propose to couple the SLR method with the Dynamical Lagrangian Remeshing (DLR) algorithm to enable local remeshing only of Lagrangian models coupling large deformation of Earth materials with large erosion.

Résumé : International audience
This paper describes an operational protocol for integrating conservation and restoration with land-use planning in islands. Conservation challenges are intensified in insular systems due to higher ecosystem vulnerability, limited spatial options, low data availability, rapid land-use change and, globally, short-term vision planning. Our operational planning protocol integrates ecological and socio-economic factors to identify the best spatial options for conserving and restoring biodiversity, inside and outside extant reserves, while minimising future land-use conflicts. Conservation and restoration targets are formulated for species, habitats and ecological processes that support biodiversity. An optimal network of priority sites is selected to achieve those targets across the landscape. The prioritisation process integrates a Conservation Costs Index to optimise conservation and restoration investments. We discuss the outcomes of the planning protocol in terms of site prioritisation, stakeholders' participation and general implications for spatial planning in insular systems. As with many islands, the study area of Réunion Island has experienced rapid urban and agricultural expansion, which threatens its unique biodiversity. Forty three per cent of the island is currently protected in a National Park but only half of this reserve network contributes to the achievement of targets. An additional 21% of land should be conserved mainly to ensure the persistence of ecological connections between the marine, terrestrial and freshwater realms. Finally we emphasize that our method doesn't substitute the land-use planning debate but is aimed to better prepare the conservation sector for negotiating future land-use allocation with other socio-economic sectors in islands

Résumé : International audience
Tourism in coastal and island environments: Continuity, limits and perspectives Coastlines and islands are particularly affected by the development of tourism worldwide. Between "desire costal" and "fantasy Island", its coveted spaces for both their tangible and intangible dimensions, open to tourism. Attracted by the economic opportunities they so desperately need, more or less aware of their comparative advantage and their limitations, they deliver resources preserved, the most vulnerable, which are the subject of complex relationships and issues.
Les littoraux et les îles sont des espaces particulièrement prisés par le développement du tourisme à travers le monde. Entre " désir de rivages " et " île fantasmée ", ces espaces convoités, tant pour leurs dimensions tangibles qu'intangibles, s'ouvrent au tourisme. Séduits par les opportunités économiques dont ils ont tant besoin, plus ou moins conscients de leur avantage comparatif et de leurs limites, ils livrent des ressources préservées, des plus vulnérables, autour desquelles se construisent de complexes relations et enjeux.

Résumé : DNA metabarcoding on soil samples is increasingly used for large-scale and multi-taxa biodiversity studies. However, DNA extraction may be a major bottleneck for such wide uses. It should be cost/time effective and allow dealing with large sample volumes so as to maximise the representativeness of both micro- and macro-organisms diversity. Here, we compared the performances of a fast and cheap extracellular DNA extraction protocol with a total DNA extraction method in retrieving bacterial, eukaryotic and plant diversity from tropical soil samples of ca. 10 g. The total DNA extraction protocol yielded more high-quality DNA. Yet, the extracellular DNA protocol provided similar diversity assessments although it presented some differences in clades relative abundance and undersampling biases. We argue that extracellular DNA is a good compromise between cost, labor, and accuracy for high throughput DNA metabarcoding studies of soil biodiversity.

Résumé : Hawaii was one of the first locations to adapt the Philippine payao concept for use in high energy, deep-water environments. Initial experimental fad deployments were made by the National Marine Fisheries Service in 1977. In 1980, the State of Hawaii started deploying FADs in a programme that has since expanded to its current status of 52 approved surface fad sites. Funding is primarily derived from federal US programmes and the FADs are primarily focused on the sport fishing community. fad sites were selected to expedite access by sport fishermen; specific sites were chosen after consultation with fishermen at public hearings. Since 1997, the FAD system has been managed on a collaborative basis between the State of Hawaii and the University of Hawaii. Hawaiian FADs evolved through two previous designs before the current system of single-sphere spar-buoy was adopted. Today's FADs have an "inverse catenary" mooring system comprised of sections of floating and sinking rope attached to a "tripod" concrete block anchor system. fad sites range between 3.2 km and 46 km from shore. Mooring depths range between 200 and 3,000 metres. Average on-site longevity is 31 months; there is no correlation between longevity and depth of mooring. Windward locations have significantly shorter lifespans than leeward locations. Ten to twenty fads are replaced each year. Each FAD costs approximately us$ 7,500 to build and deploy. Hawaiian fads are heavily used by private and commercial sport fishermen and by small-scale artisanal and commercial fishermen. Commercial pole-and-line boats occasionally use the FADs to capture skipjack tuna. Hawaiian FADs will continue to be used for various types of pelagic fisheries research.

Résumé : International audience
The emerging orbicular batfish (Platax orbicularis) aquaculture is the most important fish aquacultureindustry in French Polynesia. However, bacterial infections are causing severe mortality episodes.Therefore, there is an urgent need to find an effective management solution. Besides the supplyingdifficulty and high costs of veterinary drugs in French Polynesia, batfish aquaculture takes place close tothe coral reef, where use of synthetic persistent drugs should be restricted. Medicinal plants andbioactive algae are emerging as a cheaper and more sustainable alternative to chemical drugs. We havestudied the effect of local Polynesian plants and the local opportunistic algae Asparagopsis taxiformis onbatfish when orally administered. Weight gain and expression of two immune-related genes (lysozyme ge Lys G and transforming growth factor beta - TGF-b1) were studied to analyze immunostimulant activityof plants on P. orbicularis. Results showed that several plants increased Lys G and TGF-b1 expressionon orbicular batfish after 2 and 3 weeks of oral administration. A. taxiformis was the plant displaying themost promising results, promoting a weight gain of 24% after 3 weeks of oral administration andsignificantly increasing the relative amount of both Lys G and TGF-b1 transcripts in kidney and spleen ofP. orbicularis.

Résumé : International audience
Microsatellites (SSRs) are highly susceptible to expansions and contractions. When located in a coding sequence, the insertion or the deletion of a single unit for a mono-, di-, tetra-, or penta(nucleotide)-SSR creates a frameshift. As a consequence, one would expect to find only very few of these SSRs in coding sequences because of their strong deleterious potential. Unexpectedly, genomes contain many coding SSRs of all types. Here, we report on a study of their evolution in a phylogenetic context using the genomes of four primates: human, chimpanzee, orangutan, and macaque. In a set of 5,015 orthologous genes unambiguously aligned among the four species, we show that, except for tri- and hexa-SSRs, for which insertions and deletions are frequently observed, SSRs in coding regions evolve mainly by substitutions. We show that the rate of substitution in all types of coding SSRs is typically two times higher than in the rest of coding sequences. Additionally, we observe that although numerous coding SSRs are created and lost by substitutions in the lineages, their numbers remain constant. This last observation suggests that the coding SSRs have reached equilibrium. We hypothesize that this equilibrium involves a combination of mutation, drift, and selection. We thus estimated the fitness cost of mono-SSRs and show that it increases with the number of units. We finally show that the cost of coding mono-SSRs greatly varies from function to function, suggesting that the strength of the selection that acts against them can be correlated to gene functions.

Résumé : Since 1980 a programme of Fish Aggregation Device (fad) deployment has been carried out in the Cook Islands. Government has deployed all fads between 1 to 3 nautical miles from shore at depths ranging from 800 to 1,600 metres. The fads have undergone various designs with varying degrees of success. The average fad lifespan during the early 1980s was nine months; however, it increased to 18 months, with some fads in operation in excess of 30 months. Each fad cost between nz$ 7,000 and nz$ 9,000 to build and deploy. Since their introduction, fad have been widely accepted as a very effective apparatus in coastal small-scale fishing activities, specifically for pelagic species. Judging by the progressive behaviour of local fishing communities, there is sufficient reason to believe that fads have created productive fishing zones for Cook Islands fishermen to enable them to supply the ever-increasing local market for fresh fish. fads are an integral part of local fishing communities and provide a reasonable form of income to the increasing fishing community.
