ORBi Open Repository and Bibliography (173.157 recursos)
In may 2007, the ULg's Administrative Board (joined in June 2007 by the FUSAGx) decided to create an institutional repository and defined a strong institutional self-archiving policy to increase the visibility, accessibility and impact of the University's publications (Board's decision). This decision led to the official launch, in November 2008, of the ORBi platform including both the Academic Bibliography and the Institutional Repository of the Wallonia-Europe University Academy.

10. Relevance of pedotopographical indicators in the assessment of spatial distributions of soil depth and soil water resources under forest stands : General Methodology - Ridremont, François; Deraedt, Deborah; Robert, Tanguy; Degré, Aurore; Claessens, Hugues
Water resources constitute one of the most decisive factors of the adaptation of forest ecosystems facing climate changes. The assessment of soil water resources should lead a better understanding of forest sites vulnerability to water stress and provide appropriate management recommendations for the choice of trees species and sylvicutlural techniques. This study aims to assess the relevance of pedotopographical indicators in the assessment of spatial distributions of soil depth and soil water resources under forest stands. The study area is located in the shale-slate stones pedological context of the Belgian Ardenne ecoregion. It falls within the constrasted relief of the...

12. Corsican seagrass detritus: An opportune shelter or a copepod Eldorado? - Mascart, Thibaud; Lepoint, Gilles; Remy, François; Gobert, Sylvie; Dauby, Patrick; De Troch, Marleen
Seagrass ecosystems are extensive beds of marine flowering plants bordering tropical and temperate coastal regions. They play an important role in maintaining biological productivity and bio-geochemical cycles in the sea and support higher diversity and abundance of fauna in comparison to adjacent non-vegetated areas. The seagrass meadow primary production can be directly consumed through herbivory but the majority of the plant material falls on the sea floor during the autumnal leaf senescence. The leaf litter then degrades within the meadow or accumulates with other micro- and macrophytodetritus to form detritus accumulations on the adjacent non-vegetated sand patches. These exported accumulations...

14. Evolution de la ressource ligneuse et des stocks de carbone - Marien, Jean-Noel; Bisiaux, F.; Boulogne, M.; Craps, D.; Diowo, S.; Dubiez, Emilien; Gigaud, M.; Gond, V.; Lavialle, J.; Peltier, Régis; Pennec, A.; Peroches, A.; Procès, Pierre; Rerolles, J.; Schure, J.; Vermeulen, Cédric; Yamba Yamba, T.; Larzillière, Adélaïde
Entre 2010 et 2012, une étude complexe a été menée pour apporter des éléments qualitatifs et quantitatifs fiables sur l’évolution de la ressource ligneuse sur le bassin d’approvisionnement en bois énergie de Kinshasa. Cette étude pluridisciplinaire (Figure 1) a mobilisé l’analyse d’images satellites, la cartographie, les inventaires forestiers, la dendrométrie, des études sur la carbonisation traditionnelle et la compréhension des dynamiques sociales et économiques des zones d’étude. En plus d’analyser l’évolution de la couverture forestière sur la période de suivi (1984-2012), ce travail a permis de quantifier pour la première fois, sur des bases scientifiques et des méthodologies solides, les stocks...

15. Quaternary rainforests of the Northern Congo Basin: contribution of charcoal analysis - Morin-Rivat, Julie; Bremond, Laurent; Gillet, Jean-François; Doucet, Jean-Louis; Beeckman, Hans
In comparison with the wood charcoals uncovered in the soils of the temperate regions, charcoals from the tropical regions remain little studied yet, in particular those from the dense humid forests of Central Africa. Here we aim at showing the interest of the analysis of soil charcoals so as to understand the current environments through some examples of taxonomical identifications conducted on charcoals sampled in several soil pits in Cameroon and in the Republic of the Congo. These charcoals were hand-split then observed under an incident light microscope. The anatomical features that are hold in the charcoals and described according...

16. The end of roaming in the forest causes a loss of timber resources: the paradox of slash-and-burn agriculture - Morin-Rivat, Julie; Fayolle, Adeline; Favier, Charly; Bremond, Laurent; Gourlet-Fleury, Sylvie; Lejeune, Philippe; Beeckman, Hans; Doucet, Jean-Louis
Tropical forests are not believed as pristine anymore. Their structure and specific composition are induced by past climatic and human disturbances over years. In the African moist forests, the emergent trees are mainly light-demanding. These trees are considered to derive from the recent disturbances of the last centuries. Most of them are exploited for their timber. However, several of these tree species are currently suffering from a lack of regeneration that threatens the specific diversity of the forests and the sustainability of timber exploitation. Through dendrometric and radiocarbon analyses we found that the majority of the trees of the Congo...
