ORBi Open Repository and Bibliography (311.807 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.

  13. In Search for Marine Antarctic Cyanobacteria

    Lara, Yannick; Stelmach Pessi, Igor; Durieu, Benoit; Lepoint, Gilles; Wilmotte, Annick; Michel, Loïc
    Cyanobacteria are among the most ancient prokaryotic phyla present on the planet. They are thought to be responsible of two major geological changes and evolutionary process, the Great Oxygenation Event and the Endosymbiosis, which supported modern Life. In Polar freshwater and terrestrial ecosystems, cyanobacteria often constitute the major carbon fixers and the base of the food web. They are present in a wide range of habitat from hypersaline lakes to cryoconites. Nevertheless, their presence between the Polar front and Antarctic coast remains enigmatic. For a long time, it has been accepted that they were not present in Antarctic waters (Wilkins...

  15. Morphological diversification of the endemic Antarctic fishes Trematominae (Notothenioidei, Teleostei)

    Frederich, Bruno; Heindler, Franz Maximilian; Christiansen, Henrik; Dettai, Agnès; Lepoint, Gilles
    Adaptive radiation involves the early, rapid ecological and morphological diversification of multiple lineages from a common ancestor into new, diverging adaptive zones. Regarding this definition with emphasis on the tempo of diversification, Antarctic notothenioids represent one of the very few examples of adaptive radiation in marine fishes. Time-calibrated phylogenies suggest that the diversification of most speciose notothenioid lineages occured between 20 and 15 Ma. The subfamily Trematominae is one of those diverse subclades showing a large range of ecological niches. In the present study, we aim to describe the evolutionary history of Trematomus species. By combining a consensus time-tree and...

  16. Trophic ecology of icefishes (Notothenioidei, Perciformes) in a context of climate change

    Peignot, Quentin; Frederich, Bruno; Lepoint, Gilles; Michel, Loïc
    The Southern Ocean currently undergoes major environmental modifications related to climate change. When faced with environmental changes, all organisms are expected to have some intrinsic capacity to adapt their ecological habits to their new life conditions. Currently, biological traits of many Antarctic species are still unknown and we need such information to assess their capacity to adapt to natural and anthropogenic perturbations. Notothenioidei (Perciformes), or icefishes, are endemic to the Southern Ocean and they are an important trophic component of these marine ecosystems. Here we used stable isotopes ratios of carbon (δ13C) and nitrogen (δ15N) of two well represented genera...

  18. Isotopic compositions of North Sea marine mammals

    Damseaux, France; Pomeroy, Paddy; Sierbert, Ursula; Jauniaux, Thierry; Das, Krishna
    For over a decade, the North Sea has been undergoing significant changes due to global changes and overfishing. We conducted meta-analyses on marine mammals sampled in the North Sea to test the potential impact of changes in fish stocks on feeding behaviour of grey seals, harbour seals and harbour porpoises. Data included δ13C and δ15N values measured in blood cells and muscles from the three species. SIBER, an isotopic niche quantification approach, is used to highlight potential dietary similarity and thus competition between marine mammal species. Harbour seals sampled in Germany showed the highest δ15N values, reflecting a trophic position...
