Résumé : International audience
The main political concern in the southern areas of Madagascar is poverty alleviation. To alleviate poverty in the area, the government has chosen to enforce adjustment policies of the World Bank Group. According to the World Bank Group's argument, while artisanal mining is supposed to create significant economic, social and environmental problems, large-scale mining investment results in economic and social prosperity. This paper focuses principally on a re-analysis of the debates regarding the relationship between artisanal and large-scale mining and poverty alleviation in developing countries. Further, the paper offers an alternative viewpoint on these issues based on the example of Madagascar. In the last decade, Madagascar has experienced a significant increase in mining activity. Towards the end of the 90s, informal and artisanal mining emerged as one of the most important economic activities of the area with the development of the Ilakaka frontier. At the same time, foreign investments began to benefit from adjustment policies implemented by the government, and large-scale mining operations also commenced. As the local socio-economic system was deeply affected by these developments, it is wise to monitor the effects of each type of mining operation on poverty alleviation. On the one hand, it appears that governance insufficiency has hampered possibilities for broader economic prosperity through large-scale mining investments. On the other hand, while artisanal mining is frequently condemned by scholars, the negative comments seem to be overly pessimistic, as this activity can be demonstrated to provide considerable economic opportunities for both the native and migrant populations.

Résumé : To improve the knowledge of the survival of enteric viruses in a marine environment, the influence of physico-chemical parameters (temperature, UV, salinity) on the survival of infectious poliovirus 1 and hepatitis A Virus (HAV) in seawater was first studied, the influence of suspended solids (SS) on poliovirus adsorption and survival in seawater was then evaluated and the detection of rotavirus genome in environmental samples (shellfish, river water, treated wastewater) was finally investigated. The results show that temperature has a major impact on virus survival in seawater as the time necessary to inactivate 90 % of the virus (T-90) is 671 days at 4 degrees C and only 25 days at 25 degrees C. Ultraviolet light (42 mW s cm(-2)) rapidly inactivates viruses but HAV is more resistant (T-90 = 2.6 min) than the poliovirus 1 (T-90 = 1.3 min). By contrast, seawater salinity has no effect on virus survival. In presence of SS, 90 % to 99.9 % of the viruses were adsorbed. This adsorption does not provide any protection for viruses with low SS concentrations (3 and 15 mg L-1) but a slight increase in virus survival was observed with a high SS concentration (500 mg L-1). Finally environmental sample analysis indicated that 20 % shellfish, about 40 % river water and 40 % treated wastewater tested positive for the rotavirus genome.
Ce travail a pour but de mieux comprendre le devenir des virus en milieu marin. Dans ce cadre, l'influence de certains paramètres physicochimiques (température, UV et salinité) sur le pouvoir infectieux du poliovirus 1 et du virus de l'hépatite A (VHA) en eau de mer a été évalué, puis l'adsorption du poliovirus 1 sur les matières en suspension (MES) a été étudié, ainsi que les conséquences sur le pouvoir infectieux du virus et enfin le génome des rotavirus a été recherché en milieu naturel (eaux et coquillages). Les résultats montrent que la température est un paramètre important pour la survie des virus puisque le temps nécessaire à inactiver 90 % des virus (T90) en eau de mer est de 671 j à 4 °C alors qu'il est seulement de 25 j à 25 °C. Le rayonnement ultraviolet (42 mW s cm−2) testé en pilote expérimental, permet d'obtenir une inactivation rapide du poliovirus 1 (T90 = 1,3 min). Le VHA est plus résistant avec un T90 = 2,6 min. En revanche la salinité de l'eau de mer n'a pas d'influence sur la survie des virus. En ce qui concerne l'influence des MES, les résultats montrent qu'en présence de 3, 15 et 500 mg L−1 de Na-montmorillonite la majorité des virus est adsorbée (90 à 99,9 %). Cet état adsorbé ne procure aucune protection aux virus pour les faibles concentrations de MES (3 et 15 mg L−1) alors qu'une augmentation significative de survie est observée pour les fortes concentrations (500 mg L−1). Enfin, l'analyse d'échantillon de l'environnement a montré que 20 % des fruits de mer, environ 40 % des eaux de rivière et environ 40 % des eaux usées traitées testées contenaient du génome de rotavirus.

Résumé : Total mercury (HgT) and monomethylmercury (MMHg) were investigated in a tropical head watershed (1 km(2)) of French Guiana. The watershed includes a pristine area on the hill slopes and a former gold mined flat in the bottomland. Concentrations of dissolved and particulate HgT and MMHg were measured in rain, throughfall, soil water and at three points along the stream. Samples were taken in-between and during 14 storm events at the beginning and middle of the 2005 and 2006 rainy seasons. Dissolved and particulate HgT concentrations in the stream slightly increased downstream, while dissolved and particulate MMHg concentrations were low at the pristine sub-watershed outlet (median = 0.006 ng L-1 and 1.84 ng g(-1), respectively) and sharply increased at the gold mined flat outlet (median = 0.056 ng L-1 and 6.80 ng g(-1), respectively). Oxisols, which are dominant in the pristine area act as a sink of HgT and MMHg from rain and throughfall inputs. Hydromorphic soils in the flat are strongly contaminated with Hg (including Hg droplets) and their structure has been disturbed by former gold-mining processes, leading to multiple stagnant water areas where biogeochemical conditions are favorable for methylation. In the former gold mined flat high dissolved MMHg concentrations (up to 0.8 ng L-1) were measured in puddles or suboxic soil pore waters, whereas high dissolved HgT concentrations were found in lower Eh conditions. Iron-reducing bacteria were suggested as the main methylators since highest concentrations for dissolved MMHg were associated with high dissolved ferrous iron concentrations. The connection between saturated areas and stagnant waters with the hydrographic network during rain events leads to the export of dissolved MMHg and HgT in stream waters, especially at the beginning of the rainy season. As both legal and illegal gold-mining continues to expand in French Guiana, an increase in dissolved and particulate MMHg emissions in the hydrographic network is expected. This will enhance MMHg bio-amplification and present a threat to local populations, whose diet relies mainly on fish.

Description : Beaucoup de rumeurs, d'histoires plus ou moins extraordinaires, d'idées reçues circulent sur les araignées, véhiculées ou entretenues par la littérature fantastique et le cinéma, ou tout simplement par la tradition et le bouche-à-oreille. Mais que nous dit la science à ce propos ? Entre fantasmes, croyances et connaissances, Patrick Maréchal, Président de l'Institut Caribéen pour Nature et Culture présente une mini-conférence sur le sujet.

Résumé : International audience
PURPOSE AND METHODS: To determine the effects of cycling on a subsequent triathlon run, nine male triathletes underwent four successive laboratory trials: 1) an incremental treadmill test, 2) an incremental cycle test, 3) 30 min of cycling followed by 5 km of running (C-R), and 4) 30 min of running followed by 5 km of running (R-R). Before and 10 min after the third and fourth trials, the triathletes underwent pulmonary function testing including spirometry and diffusing capacity testing for carbon monoxide (DL(CO)). During the C-R and R-R trials, arterialized blood samples were obtained to measure arterial oxygen pressure (PaO2). During all trials, ventilatory data were collected every minute using an automated breath-by-breath system. RESULTS: The results showed that 1) the oxygen uptake (VO2) observed during subsequent running was similar for the C-R and R-R trials; 2) the ventilatory response (VE) during the first 8 min of subsequent running was significantly greater in the C-R than in R-R trial (P < 0.05); 3) only the C-R trial induced a significant increase (P < 0.05) in residual volume (RV), functional residual capacity (FRC), and the ratio of residual volume to total lung capacity (RV/TLC); and 4) although a significant decrease (P < 0.05) in DL(CO) was noted after C-R, no difference between the two exercise trials was found for the maximal drop in PaO2. CONCLUSIONS: We concluded that 1) the C-R trial induced specific alterations in pulmonary function that may be associated with respiratory muscle fatigue and/or exercise-induced hypoxemia, and 2) the greater VE observed during the first minute of running after cycling was due to the specificity of cycling. This reinforces the necessity for triathletes to practice multi-trial training to stimulate the physiological responses experienced during the swim-cycle and the cycle-run transitions.

Résumé : The slides were taken on collecting trips sponsored by the William L. Bryant Foundation, where books, music and art indigenous to the regions were gathered. The are organized by geographical location.
The town of Bath is located in the John Crow Mountains in Saint Thomas, Jamaica. Mineral springs flow from the rocks and are piped into the bath house, pictured, where the cold and hot waters of the springs are mixed together. The water’s high mineral (sulfur and lime) content is believed to have medicinal properties. The bath has been officially known as the Bath of the Saint Thomas the Apostle. Bath Fountain Hotel and Spa is run by the Jamaican Ministry of Tourism. In front of the building are many automobiles including a taxi. Along the stream, pictured, are dasheens (taros), ferns, palms, and other trees. Slide labeled Jam. St. Thomas min bath at Bath (SE).
