ORBi Open Repository and Bibliography (327.254 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.

  3. Feeding ecology of sea stars of the Southern Ocean: possible influence of sea ice on trophic niche partitioning

    Le Bourg, Baptiste; Blanchard, Alice; Danis, Bruno; Jossart, Quentin; Lepoint, Gilles; Moreau, Camille; Michel, Loïc
    Sea stars (Echinodermata: Asteroidea) are a key component of the Southern Ocean benthos, with 12% of the known sea star species living in the Southern Ocean. This group is considered quite resistant to seawater temperature changes. However, it is still likely to be impacted by the modifications of environmental conditions and food web functioning linked to climate change occurring in the Southern Ocean. Indeed, reduced abundances or disappearance of common prey put sea star populations at risk. However, trophic diversity, and notably capacity to switch prey according to environmental conditions (i.e. trophic plasticity) could help Southern Ocean sea stars to...

  5. Otolith shape development in young-of-the-year chub (Cyprinidae, Squalius cephalus)

    Gibert, Pierre; Bounket, Bernadette; Morat, Fabien; Carrel, Georges; Maire, Anthony; Gennotte, Vincent
    Only a very few studies have focused on the influence of age on the otolith morphometry of cyprinids. Chub Squalius cephalus (L.) is an abundant and widespread European rheophilic cyprinid. Otolith shape analysis was used in many studies to characterize diverse local populations. In the present study we have evaluated the influence of age on the shape of otoliths during the early life of Chub when reared for experiment. Features of the sagittae, asterisci, and lapilli of laboratory-hatched larvae of the chub, were investigated until day 180 after hatching. Our observations showed that the lapilli and the sagittae were both present...

  11. Underwater silence world: the end of the dogma

    Parmentier, Eric
    Passive acoustics can offer inexpensive, non-invasive and no-destructive means of assessing temporal and spatial patterns in the distribution of individuals engaging in calling. In marine environments, passive acoustic recording methods can be used at depths not accessible to humans, independent of weather conditions, and for a long term. However, these studies have often restricted their investigations to the monitoring of one or two aquatic species. One reason of this loss of information is quite easy to explain: most of the sounds can be detected but cannot be identified. In many families, calling abilities are described in one or two species...

  14. Effects of fluid preservation on sea star stable isotope composition: do they prevent the use of museum collections for trophic ecology studies?

    Le Bourg, Baptiste; Lepoint, Gilles; Balthasart, Pierre; Michel, Loïc
    Stable isotope analyses (SIA) of carbon (δ13C) and nitrogen (δ15N) are now a common tool to investigate the trophic ecology of organisms and the functioning of food webs. After field sampling, organism tissues are usually preserved frozen or dried before subsequent analysis. However, museum samples, or samples not initially collected for SIA, are often fixed in preservative solutions such as formaldehyde or alcohol. These preservation methods may alter stable isotope ratios in tissues, making them difficult to interpret. Consequently, these effects should be quantified. Here, we investigated long-term effects of common preservation methods on δ13C and δ15N values of sea...

  15. Evolution de la forme des otolithes de juvéniles de chevaines (Cyprinidae, Squalius cephalus)

    Gibert, Pierre; Bounket, Bernadette; Morat, Fabien; Carrel, Georges; Maire, Anthony; Gennotte, Vincent
    L’analyse de la forme des otolithes est utilisée pour caractériser diverses populations locales, mais seulement quelques études s’intéressent à l’influence de l’âge sur la forme des otolithes. Le Chevaine Squalius cephalus (L.) est un poisson cyprinidé rhéophile très abondant et avec une large aire de répartition en Europe. Dans l’étude présentée, nous avons observé le lien entre l’âge et la forme des otolithes durant les premiers mois de la vie de Chevaines élevés en condition expérimentale. Les caractéristiques de forme des sagittae, asterisci, et des lapilli de chevaines éclos en laboratoire ont été étudiées jusqu’à l’âge de 180 jours post-éclosion. Nos...

  19. Effects of fluid preservation on sea star stable isotope compositions: Can museum collections be used for trophic ecology studies?

    Le Bourg, Baptiste; Lepoint, Gilles; Balthasart, Pierre; Michel, Loïc
    Stable isotope analyses (SIA) of carbon (δ13C) and nitrogen (δ15N) are a common tool to investigate the trophic ecology of marine organisms. After field sampling, animal tissues are usually preserved frozen or dried before subsequent analysis. However, museum samples, or samples not initially collected for SIA, are often fixed in preservative solutions. These preservation methods may alter stable isotope ratios in tissues and these effects should be quantified. Here, we investigated long-term effects (1, 3, 6, 9 and 12 months) of four preservation methods (freezing, alcohol, formaldehyde, drying) on δ13C and δ15N values of sea stars. In particular, we tried...
