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.
Dortoirs urbains et dispersion diurne des étourneaux Sturnus vulgaris au pays de Liège en 1978-79. - Metzmacher, Maxime; Ghiot, Alain; Jacob, Jean-Paul; Ruwet, Jean-Claude
During the last decade, strarlings have built up considerable urban populations in the city of Liège,causing much trouble to inhabitants in the vicinity of the roosting sites. This success migh be attribuable to the sheltered situation of the city in a deep valley, abundance of large trees in green spaces along bank of the river Meuse and in public parks, good situation amid pastures in the countryside, and on important migration routes.
Before any attempt to reduce this underisable population, the city's authorithies have promoted a research on the localisation, evaluation, evolution of roosting groups, as well as on pre-roosting...
Facteurs climatiques et reproduction du Pinson des arbres (Fringilla coelebs L.) sur le plateau des Hautes-Fagnes - Metzmacher, Maxime
The influence of climatic and behavioural factors on the progress and success of the breeding cycle of chaffinches (Fringilla coelebs) has been investigated on the Hautes-Fagnes plateau (Belgium). From april to july 1980, three line transects (two of 1,6 and one of 1,2 km) in Norway spruce plantations were regularly prospected. The estimation of the number of territorial males was improved by a sonographic analysis of their songs, The breeding season has been marked twice by unfavourable weather conditions. In april, a cold-wave produced flocks reformation, but after then the cycle could evolve normally. In june-july, heavy rains seem to...
Organisation spatio-temporelle de la reproduction chez le Moineau espagnol Passer hispaniolensis en zone semi-aride - Metzmacher, Maxime
Nests supports are made atractive on a high-perched position as far as the Spanish sparrow is concerned. Such supports should be closely-packed, provided with a plethora of sprigs and located near cereal fields. The breeding colonies of early clutches that gather several thousands of birds in Orania are comparatively independant of aquatic areas. High density nest zones within a colony of birds seem to be related not only to the supports themselves but also to the diversified vegetal environment.
Simultaneous species reproduction in the Oran area is carried out in each region accordingly. Futhermore, results reveal that the reproduction may...
Le menu des jeunes Moineaux domestiques, Passer domesticus L., et espagnols, Passer hispaniolensis TEMM., en Oranie. - Metzmacher, Maxime
The composition and the structure of the nestling sparrows were studied in the north-west of Algeria. The nestling's food of the two sparrows consisted mainly of animal food in the beginning of the nestling period, the vegetable fraction of the diet become more important at the end of this period. Preys hierarchy can vary with nestling age, colony situation and season. The two sparrows, and their recognised age-classes, have similar diet structure. The distribution of preys between the different taxa revealed that the sparrows are generalist predators. The spanish sparrow,however, exhibit sometimes a strong specialisation.
