Endemic to the Democratic Republic of Congo (DRC) and classified as Endangered by IUCN, the Bonobo survival depends exclusively on management measures taken by a country having to deal concomitantly with several problems affecting its development. The current government’s intention to designate new protected areas need to be complemented by effective long-term conservation programs, taking into account both bonobos populations requirements and local socio-economic realities. As part of a WWF conservation program, our study focuses on recently discovered Bonobo populations in West RDC, an eccentric location of the species range. The region is characterized by numerous anthropogenic activities including logging and cattle ranching and is composed of forest-savannah mosaics in which Bonobo has hardly ever been studied in comparison with those evolving in central DRC rainforests. Preliminary observations already indicate that these Western populations differ from other known populations in terms of habitat use, with regular savannahs patches crossing and savannah fruits consumption. To shed further lights on species adaptation’s spectrum, our study investigates local population density; nesting sites choice; and diet composition. Here we present a baseline population density derived from 5 walks along transects using marked-nest count method and we discuss factors inducing nesting sites choice. Ultimately, our results should allow for the formulation of specific management recommendations to be used in regional conservation program. [less ▲]

The Bonobo could be one of the species facing the biggest conservation challenge in the years to come. Endemic to the West Democratic Republic of Congo (DRC), its survival depends exclusively on the management measures taken by a country having to deal concomitantly with many problems affecting its development, i.e. demographic explosion, poverty, insecurity and deforestation. But the survival of bonobos, classified as Endangered by IUCN (2010) and restricted to a relatively small range, will require newly designated and effective protected areas. This will imply long-term conservation programs, taking into account the bonobos’ populations requirements, as well as the local socio-economic needs and realities. In 2005, a large population of bonobos has been identified in Western DRC, in a rather eccentric part of the species range compare with the best known populations inhabiting the rainforest of center DRC. The Western region, known as the Lake Tumba Landscape, is characterized by a relatively poor rural human population, an active bushmeat trade, and is divided into several logging concessions and cattle ranches. In 2007, WWF initiated a vast conservation program in the area, including an eco-tourism project involving the habituation of 2 bonobos populations. Until now, only sparse information has been gathered but preliminary studies indicate that habitat use by bonobos – a forest-savannah mosaic – differs substantially from that of other known populations. The objective of the research is to define the eco-ethological profile of those 2 populations. For this purpose, we will characterize diet and food preferences, examine population density and try to identify factors inducing nesting sites’ choice. This information will help understanding habitat use by bonobos in the Western region, and should allow us to come up with specific management measures to be adopted by logging concessions, WWF and ICCN as part of the region’s conservation program.

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 %.

La mise en oeuvre coordonnée de mesures d'aménagement et d'urbanisme, de management environnemental et d'écologie industrielle est préconisée pour contribuer à une plus grande durabilité des zones d'activité économique.

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 ▲]
