Aim. Ecogeographical body size variation in vertebrates (e.g., Bergmann’s rule) has long been recognized. However, the patterns and causes of intraspecific ecogeographical body size variation in ectotherms, and in amphibians in particular, are strongly debated. We identified the relationship between bioclimatic variables and body size predicted a priori by alternative hypotheses (heat balance; endurance, seasonality, starvation resistance, water availability; primary productivity, parental investment) proposed to explain ecogeographical patterns of body size in ectotherms, and we evaluated the relative support of these hypotheses in explaining body size variation of the Italian crested newt, Triturus carnifex. Location Twenty-three populations covering the whole range of T. carnifex (Austria, Croatia, Italy and Slovenia) Methods. We obtained data on body size (SVL) of 2639 adult newts from direct measurements and the literature; we obtained high resolution environmental data for the sampled localities. We used an information-theoretic approach to evaluate the support of the different hypotheses, by the data. We also integrated information on population genetics in our models. Results. We observed strong geographic variation of body size. The best AIC models showed that populations with larger body size are associated with cold climates and secondarily with high primary productivity. Furthermore, sexual dimorphism increases in cold climates, as the increase in body size was stronger for females. When taking into account population genetics, we did not find support for relationships with the other variables. Main conclusion. Our results are consistent with three hypotheses proposed to explain ecogeographic variation in amphibians: heat balance, increased parental investment of females and productivity. Information theory provides the framework for comparing hypotheses rather than looking for patterns. We suggest that evaluating the support of mechanisms can provide better insights than simply assessing whether ecogeographical variation is in agreement with some ‘rule’. [less ▲]

Hydrological measurements (temperature, conductivity, salinity) have been realized in 1982 and 1984 along the Calvi - Nice axis from the Corsican coast to 30 miles offshore. The data have shown a thermohaline front separating low saline coastal waters of atlantic origin from high saline offshore waters of deeper origin. A succession of divergences and convergences is associated to that discontinuity. During spring, the front is emphasized and the water upwellings reach the surface. During summer, the upwellings are limited by the vertical stratification but an isopycnal inclination is always observed from the front to the coast. [less ▲]

Nutrients (nitrate, ammonia, silicate, phosphate) and primary production rates have been determined in the Liguro-Provençal front and adjacent water masses in March, June and October 1984. Nutrients vary seasonally in relation with the spring netphytoplankton bloom but also with the mixing and the stratification of the waters. Maxima of primary production are generally found in areas where nutrients supply and light utilization are favourable to the phytoplankton growth. Specific differences in the phytoplankton composition probably explain the productivity variations observed at some periods. [less ▲]

Cruises realized on board of the RV "Recteur Dubuisson" in the region of the Liguro-Provençal Front (Corsican area) allow the description of the chlorophyllian pigments distribution from the coast to 30 miles offshore. During spring, maxima of phytoplankton are found on the thermohaline front. During summer (June to October), chlorophyll maxima are situated below the stratified layer which slopes down from offshore to the coast. [less ▲]

A 3-D, high resolution model is used to investigate the impact of the Calvi canyon on the ecohydrodynamics in early spring conditions. Numerical runs are performed to simulate the nitrate distribution. Results show that the canyon topography generates high downwelling (upwelling) in the western (eastern) part of the canyon. Downwelling is larger than upwelling within the canyon leading to a net downward nitrate transport there, while upstream and downstream of the canyon there are regions of upwelled water richer in nitrate. Simulations are performed for NE, upwelling favorable, wind conditions where data of nitrate concentration are available for model validation. [less ▲]

Le projet eCole a pour objectif de soutenir le développement des socles de compétences visés dans l’enseignement primaire et secondaire de la communauté française de Belgique. Il propose une plateforme en ligne reprenant par compétence des tâches susceptibles de les servir (http://www.e-cole.be). Environ 430 tâches y sont jusqu’ici répertoriées. Les deux premières années (2006 et 2007) ont été consacrées à la conception de l’outil, à la sélection et la création de tâches utiles au développement des compétences « lire » et « écrire » en français à destination des enfants de 10 à 14 ans. La troisième année (2008) est dédiée à son expérimentation et au déploiement d’activité au service du développement de compétences en mathématiques. Nous décrirons dans les paragraphes qui suivent une brève description de l’outil, de sa mise en oeuvre et des perspectives qui en résultent. [less ▲]

S'intéresser au phénomène des « bandes urbaines » en Belgique, et plus particulièrement aux groupements de jeunes pairs issus de l’immigration africaine subsaharienne, amène immanquablement à se pencher sur la sociologie de l'Ecole de Chicago. Une revue de la littérature existante nous conduit à nous tourner vers des auteurs comme H. S. Becker, A. V. Cicourel ou encore W. F. Whyte. Il importe cependant de s’interroger sur la pertinence de cet héritage intellectuel dans un contexte spatialement et temporellement différent. On sait en effet que la sociologie de l’Ecole de Chicago s’est développée parallèlement à la ville de Chicago elle-même et qu’elle prend en considération, entre autres, la dimension « immigration ». Dès lors, que retenir de la sociologie de l’Ecole de Chicago pour l’analyse d’autres terrains ethnographiques ? Prenant pour exemple le cas des « bandes urbaines » à Liège, ma communication aura pour objet d’examiner les apports de ce courant pour l’analyse de phénomènes déviants actuels. Je montrerai qu’au-delà d’enseignements théoriques (tels que l’idée d’apprentissage de la déviance par les pairs via H. S. Becker et le fait que les quartiers pauvres se caractérisent par une forme d’organisation sociale spécifique via W. F. Whyte), les apports méthodologiques de l’Ecole de Chicago et de l’anthropologie peuvent également être mobilisés pour des études contemporaines d’intérêt criminologique. Pour ce faire, outre les auteurs déjà cités, je m’appuierai aussi sur des auteurs comme D. Fassin, C. Ghasarian et M. Godelier. [less ▲]
