ORBi Open Repository and Bibliography
(146.867 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.

Comment étudier la communication entre dauphins captifs et soigneurs ? - Servais, Véronique; Delfour, Fabienne
Cet article présente la manière dont nous avons abordé la communication interspécifique dans le cas d’une étude toujours en cours sur les systèmes de communication formés par des soigneurs et leurs dauphins au Parc Astérix de Paris. La première partie aborde les principales difficultés théoriques et méthodologiques qui se sont posées à nous pour la description de ce système de communication hétérogène. La seconde partie présente le cadre théorique mobilisé, les choix méthodologiques et les résultats attendus (les analyses sont toujours en cours). La troisième partie pose la question de l’intercompréhension sous la forme d’une compréhension sociale qui n’exclut pas...

Cues from introduced fish alter shelter use and feeding behaviour in adult alpine newts - Winandy, Laurane; Denoël, Mathieu
Amphibians are particularly affected by alien fish introductions and are declining worldwide. However, the behavioural mechanisms behind the observed cases of coexistence and exclusion patterns between adult amphibians and fish are poorly understood. In the present study, we aimed at testing the hypothesis that adult newts display different feeding and space use behaviour in the presence of fish cues (i.e. access less food resources and use more shelters than when fish cues are absent). To achieve this we measured behavioural patterns in 100 adult Alpine newts (Mesotriton alpestris) in a replicated laboratory design (20 tanks × 7 replicates across time)....

Sensitivity to tactile novelty in the terrestrial isopod, Porcellio scaber - Anselme, Patrick
Invertebrates have been studied at biochemical, ecological, and behavioural levels, but current knowledge about the impact that learning may have on behaviour is rather sparse. The present study aimed to examine the sensitivity of isolated rough woodlice (Porcellio scaber Latreille 1804) to the tactile novelty of their environment. A simple way to test this issue was to refer to the place preference paradigm, traditionally used in vertebrates. In Experiment 1, woodlice were placed in a compartment for 30 min in order to assess their ability to develop habituation in the absence of reward. In Experiment 2, woodlice were exposed to...

Effects of a sublethal pesticide exposure on locomotor behavior: A video-tracking analysis in larval amphibians - Denoël, Mathieu; Libon, Sylvie; Kestemont, Patrick; Brasseur, Catherine; Focant, Jean-François; De Pauw, Edwin
Organochlorine pesticides such as endosulfan have been shown to have both lethal and sublethal effects on amphibians. In this context, behavioral endpoints have proved their usefulness in evidencing impacts of such chemicals at environmental concentrations that do not necessarily cause mortality. The recent development of video-tracking technologies now offers the possibility of accurately quantifying locomotor behaviors. However, these techniques have not yet been applied to evaluating the toxicity of pesticides in amphibians. We therefore aimed at determining the potential toxicity of endosulfan on endpoints associated with locomotion after short-term environmental endosulfan exposure in Rana temporaria tadpoles and at using these...

ESTUDIO COMPORTAMENTAL DE UN GRUPO DE PRIMATES Lagothrix sp. É. GEOFFROY, 1812 (ATELIDAE, PRIMATES) EN SEMI CAUTIVERIO EN UN CENTRO DE RESCATE EN LA AMAZONÍA ECUATORIANA - Carrillo Bilbao, Gabriel Alberto; Martin, Sarah; Martinage, Alice; Rigaux, Gaëlle
El comportamiento de un grupo de Lagothrix sp. en semicautiverio fue estudiado durante los meses de Febrero a Junio 2011. El grupo está conformado por siete hembras y cuatro machos. El proyecto Primates Ecuador mantiene un protocolo en el cual se estudió el comportamiento por medio de barridos y de focales desde las 8:00 hasta las 17:00. Adicionalmente se estudió el uso del estrato. En cuanto al uso de tiempo, se observó dos picos altos del comportamiento de alimentación entre las 8-8h59 y entre las 13h-13h59 que corresponden con la alimentación artificial que se les proporciona en el centro de...
