Il existe de nombreuses formes de blocages susceptibles de limiter la reproductibilité des expériences d’éco-quartiers, par exemple en termes de maîtrise foncière ou par la nécessité pour des acteurs de la construction de sortir de leurs démarches traditionnelles. Notre recherche s’est focalisée sur un aspect à la fois partiel et essentiel de la problématique, en l’occurrence les préférences résidentielles. Nous avons, pour ce faire, réalisé une enquête sur le potentiel commercial de la formule de l’éco-quartier. Cette enquête, conduite par la méthode de l’évaluation contingente, s’est focalisée sur les ménages qui alimentent le peuplement des banlieues périurbaines. Pour le contexte investigué - la Wallonie - et pour le proche futur, il ressort de l'enquête que l’éco-quartier ne va pas conduire à des effets significatifs sur l’endiguement de la périurbanisation. Répondre par la négative quant à la possibilité d’endiguer l’étalement urbain par la multiplication des projets d’éco-quartiers ne signifie pas pour autant que cette formule ne puisse pas jouer un rôle significatif dans la production immobilière future. Si l’on cherche à donner une estimation crédible quant à la demande susceptible de choisir la formule de l’éco-quartier plutôt que la formule du lotissement périurbain, nos résultats poussent à avancer l’ordre de grandeur des 10 %.

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 ▲]
