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.
Linking bees and flowers: mutualistic interaction networks to study ecosystem functioning - Uyttenbroeck, Roel; Monty, Arnaud
In recent years, much attention is going to pollinators, as they are important for the increasing food production while being threatened by agricultural intensification and other environmental drivers. While honeybees (Apis mellifera L.) are generalist according to their flower preferences, wild pollinators’ flower preferences can go from generalist to very specialist. The same goes for plant species, which can be generalist or specialist in the pollinator species they need to get pollinated. The combination of a set of generalist and specialist plant species with a pollinator community consisting of generalists and specialists in a certain habitat, results in an interaction...
Impact of Climate Change on “Aphid - Natural Enemies” Relationship - Boullis, Antoine; Oostrom, Marjolein; Francis, Frédéric; Verheggen, François
While the effects of global atmospheric changes on vegetation and associated insect populations (bottom-up interactions) are increasingly studied, how these gases affect the interactions between insects and their natural enemies (top-down interactions) is less clear. As the efficacy of natural enemies is governed largely by behavioral mechanisms, changes in their prey-seeking behavior or the behavior of insect prey defenses can change the dynamics of insect populations.
The impact of increases in atmospheric carbon dioxide concentrations on aphid population dynamic is well documented. However, nothing about their chemical ecology is reported in the literature. Aphids are using many chemical signals to communicate...
Projet Termitofuel: les termites et leurs symbiontes pour mieux valoriser la biomasse ligno-cellulosique - Bauwens, Julien; Tarayre, Cédric; Brasseur, Catherine; Destain, Jacqueline; Vandenbol, Micheline; Portetelle, Daniel; Thonart, Philippe; De Pauw, Edwin; Haubruge, Eric; Francis, Frédéric
L’exploitation actuelle de la biomasse ligno-cellulosique, extrêmement abondante sur Terre, est liée à la production de déchets relativement peu valorisables. C’est pourquoi le projet TERMITOFUEL étudie la digestion du bois chez les termites, grâce à une approche pluridisciplinaire, en vue d’améliorer la production de bioéthanol de seconde génération. Au sein de l’Unité d’Entomologie Fonctionnelle et Evolutive, l’approche protéomique est employée afin d’identifier les micro-organismes présents dans le tube digestif des termites et caractériser les activités enzymatiques.
