Evidence for the local depletion of bay duiker Cephalophus dorsalis, within the Ipassa Man and Biosphere Reserve, north-east Gabon
Abstract
Malgré son statut de protection, la Réserve d'Ipassa, au nord-est du Gabon, a subi d'intenses activités de braconnage. Des études récentes des mammifères ont montré que la réserve en abrite encore une grande diversité mais que leur densité a décliné de façon dramatique au cours des deux dernières décennies. Nous avons évalué les changements de la diversité des espèces de céphalophes dans la réserve en comparant les données récoltées il y a 20 ans et celles de 2005-2006 dans la même région. Les deux seules espèces présentes aujourd'hui sont le céphalophe bleu et le céphalophe de Peters. La densité des céphalophes bais était de 7,1 individus/km2 dans les années 1980 mais il semble qu'il n'y en ait plus à cet endroit. Comme la chasse pour l'approvisionnement fut la seule activité pratiquée dans la réserve au cours des 20 dernières années et que le céphalophe bai est une espèce particulièrement prisée par les chasseurs de la région, il est très probable que la chasse soit la raison de cette disparition locale.

In Gabon, the small Blue duiker is significantly less abundant in remote forests within the boundaries of the Ivindo National Park than in hunted areas with similar vegetation cover close to the town of Makokou, while the larger Peter's and Bay duiker are less abundant or even depleted.
“For example, in Gabon, the small Blue duiker is significantly less abundant in remote forests within the boundaries of the Ivindo National Park than in hunted areas with similar vegetation cover close to the town of Makokou, while the larger Peter's (Cephalophus callipygus) and Bay duiker (C.dorsalis) are less abundant or even depleted (van Vliet 2008, van Vliet et al. 2007).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
