During the years '86 to '88, 192 badger dens were visited in the province of Luxembourg in Belgium. Ninety of them were occupied by badgers. The previous census ('82/'85) revealed only 66 inhabited setts. The situation of the species seems therefore better now. That small population increase is thought to be the consequence of the change in the rabies control policy. Systematic gassing of dens was stopped in 1982 and oral vaccination of foxes started in 1986. Three vaccination campaigns were conducted in 1986 and 1987 in an area extending along the border of the grand duchy of Luxembourg and covering approximately half of the badger census zone. In the vaccination area, more new dens were digged and more old ones were occupied again than in the unvaccinated zone whereas a greater number was abandoned or destroyed in the latter one. Nowadays, forestry (namely clear cuttings) and poaching are currently viewed the main threats on the badger in the province of Luxembourg. [less ▲]

An inventory of the Coccinellidae present in the collection of the Department of functional and evolutionary Entomology (ULg - Gembloux Agro-Bio Tech) was performed on the period extending from 2001 to 2009. This collection is essentially made up of insects collected by first year students. The aim of this work is to assess the evolution of the species belonging to this family with special interest in their relative amount and the species richness. This study was focused on the data from Wallonia and Brussels-Capital Region (Belgium), not enough insects having been collected in Flanders. Among the identified individuals, 27 species were observed, including 21 belonging to the subfamily of Coccinellinae, 2 to Epilachninae and 4 to Chilocorinae. Most of the species are native to Belgium. However, Harmonia axyridis (Pallas 1773), an exotic species coming from the South-East of Asia, was introduced in Belgium in 1997. This alien ladybird was firstly collected by the students in 2002 and the amount of collected individuals does not cease increasing until 2009. By contrast, a decrease of species richness, as well as the relative amount of Adalia bipunctata (L. 1758), Propylea quatuordecimpunctata (L. 1758) and Psyllobora vigintiduopunctata (L. 1758), is highlighted. The link between these evolutions is discussed. [less ▲]

Cet article examine l’évolution et la modulation des usages des « objets médiateurs » en design industriel depuis l’avènement des outils de CAO (Conception Assistée par Ordinateur). Ces outils ont longtemps été étudiés en regard des avantages et inconvénients que leur utilisation constituait pour le processus de conception, et toujours en comparaison des outils dits « traditionnels » (dessins à main levée, maquettes) [9 ; 5]. L’article suggère d’étudier plutôt ces outils, médiateurs de l’activité de conception, pour leur complémentarité qui apparaît parfois très en amont du processus de conception (dès la phase conceptuelle). Les bases théoriques qui structurent l’ensemble de l’intervention sont présentées et discutées à la lumière de cette suggestion tout comme les principaux résultats d’une intervention in situ, pour une objectivation des nouvelles pratiques « métier ».

Forest planning is more and more made of activities which require to take into account a great amount of various sets of ecological, economical and social data which have to be considered in a diversity of space and time-scales. Facing such complexity the managers need of guidance in coming to the right decision. Some decision support systems are presented and briefly described as concerns nature, objectives and possible applications to concrete situations. [less ▲]

On the basis of an exhaustive consultation of the literature describing the temporal evolution of land cover in arid, semiarid and dry subhumid regions of West Africa, this study shows that the deforestation trend has been very important during the second half of the 20th century. This trend to deforestation is globally large (2% per year) and is clearly alarming. Although our results differ from FAO's official data, it is demonstrated that those are questionable. In addition, if dense woody formations have been strongly reduced in the study area, our study indicates that degraded woody formations are currently declining. Our results clearly go against the recent conclusions of some authors preaching the idea of a 'greening Sahel'. [less ▲]

Tillage reduction seems to affect porosity distribution, orientation and connectivity. Soil samples were removed from plots under conventional tillage or reduced tillage. Their water retention curves were measured, and the characterization of soils porosity was made using x-ray microtomography measurements. Results show differences in the meso as well as in the macroporosity. [less ▲]
