ORBi Open Repository and Bibliography
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.
Biodiversity and ecosystem services: think functional! - Uyttenbroeck, Roel; Hatt, Séverin; Paul, Aman; Boeraeve, Fanny; Francis, Frédéric; Danthine, Sabine; Frederich, Michel; Dufrêne, Marc; Bodson, Bernard; Monty, Arnaud
During the last years, several studies and reviews have considered the relation between biodiversity and ecosystem functioning or the provision of ecosystem services. Many studies found that plant functional traits and plant functional diversity (FD) are key drivers in this relation in terrestrial ecosystems. Researchers used different methods to obtain a gradient in plant FD to examine the effect on ecosystem services, going from observational studies of natural communities to synthetic assemblages. Furthermore, different methods exist to quantify plant FD going from simple functional trait richness to indices, distance-based frameworks and the division into FD components. In the AgricultureIsLife project,...
Le coût CO2 du réveillon de Noël - Ozer, Pierre
Pour vous, j’ai décortiqué le folder publicitaire Spécial Noël « Nos petits prix vous mettent en appétit » de l’hypermarché Carrefour pour préparer le repas familial tant attendu. Et voici ce que j'ai pu concocter pour huit personnes (200 g de produits à tête) avec, entre parenthèses, les kilomètres parcourus entre le pays de production et la Belgique ainsi que les kilogrammes de CO2 émis uniquement pour le transport (souvent aérien et intercontinental) de ces produits achetés. Rappelons ici que le transport aérien émet, en moyenne, 60 fois plus de CO2 que le transport par voie maritime.
Observations coupled to the overpasses of the polar vortex over mid-latitude Europe in winter 1995-1996 - Hennen, Olivier; De Mazière, Martine; Van Roozendael, Michel; Lambert, Jean-Christopher; Mahieu, Emmanuel; Demoulin, Philippe; Roland, Ginette; De Backer, Hugo
The spring 1996 polar vortex was very deep and cold, with temperatures down to the ice formation threshold, and persisted until March. The northern hemisphere ozone decrease in winter 1995-1996 was larger than ever before in the nineties. Particularly at the European mid-latitudes, transport of air masses from the polar vortex towards mid-latitudes had a noticeable impact on the stratospheric temperatures and composition. Such was not observed that clearly in the latest winter 1996-1997. In this work, signatures of polar vortex overpasses in spring 1996 at several European mid-latitude stations are indicated. Most significant events have been observed at these...
A framework for using decision-support tools at various spatial scales for the management of irrigated agriculture in semi-arid West-Africa - Wellens, Joost
The Kou watershed, situated in the Southwestern part of Burkina Faso, has succumbed since a couple of decades to a typical theater play of anarchistic water management. With its 1.800 km², this small watershed includes the second largest city of Burkina Faso (Bobo-Dioulasso), a former state run irrigated rice scheme and several informal agricultural zones. Despite the abundance of water resources, most water users find themselves regularly faced with shortages due to an increase in population and low irrigation efficiencies. Local stakeholders are hence in need of easy to use and low-cost decision support tools for the monitoring and exploitation...
Species richness and speciation in the genus Lepilemur in northwestern Madagascar - Wilmet, Leslie; Vermeulen, Cédric; Beudels-Jamar, Roseline; Schwitzer, Christoph
Sportive lemurs of the genus Lepilemur are small, nocturnal folivorous lemurs that are exclusively arboreal and generally have small distribution ranges. Owing to these characteristics, they are particularly negatively affected by deforestation and habitat fragmentation, which is reflected by the recent uplisting of many of the 26 Lepilemur species into one of the threatened categories of the IUCN Red List.
The main aim of this study is to understand the evolutionary mechanisms underlying species richness and speciation processes of the genus Lepilemur in northwestern Madagascar, and to test the predictions of the Inter-River-System biogeographic model of lemur distribution patterns proposed by...
