Modalités de la colonisation de l’île de la Réunion par le Bulbul Orphée (Pycnonotus jocosus)

Abstract: Le Bulbul orphée Pycnonotus jocosus a été introduit sur l'île de la Réunion au début des années 1970. La complexité du relief et la différence de répartition de la pluviosité sur les deux versants, font de la Réunion un modèle pour l’étude des processus de colonisation. Nos résultats mettent en évidence des vitesses de colonisation différentes des versants, la préférence allant aux milieux chauds et pluvieux qui sont colonisés en premier et où la densité de population est, encore à l’heure actuelle, largement … Show more

“…This recently‐introduced bulbul is currently restricted to ecotone areas and infrequently enters native forests, but it has a high propensity to fast colonization after introduction and naturalization (Clergeau & Mandon‐Dalger, 2001), enabling it to rapidly adapt to novel environments (Amiot et al, 2007). It is also well known for spreading invasive exotic plant species through zoochory (Mandon‐Dalger et al, 1999). Hence, its possible expansion into uninvaded habitats needs to be cautiously monitored since it may pose serious conservation issues for native plant assemblages, which can moreover be affected by a reduction of their dispersal by local functional extinctions of native birds (Anderson et al, 2021).…”

“…: Ardisia crenata, Clidemia hirta, Flacourtia spp., Fuchsia spp., Hedychium spp., Lantana camara, Ligustrum robustum subsp. walkeri, Litsea glutinosa, Psidium cattleianum, Rubus alceifolius, Schinus terebenthifolius, Solanum mauritianum) dont s'alimentent plusieurs oiseaux exotiques d'introduction relativement récente comme le Rossignol du Japon Leiothrix lutea (Tassin & Rivière, 2001) ou le Bulbul orphée Pycnonotus jocosus (Mandon-Dalger et al, 1999). L'invasion de Clidemia hirta dans l'est de l'île apparaît ainsi étroitement liée à celle de Pycnonotus jocosus (Mandon-Dalger et al, 2004).…”

“…Ainsi, l'étude de la distribution des invasions le long d'un gradient altitudi nal est susceptible d'apporter des éléments nouveaux sur l'invasibilité d'une gamme continue de milieux, naturellement ordonnés selon la température ambiante . L'île de La Réunion, soumise à des invasions biologiques nombreuses (Macdonald et al, 1991 ;Mandon-Dalger et al, 1999 ;Tassin & Rivière , 1999), et disposant d'un puissant gradient altitudinal, constitue un modèle biologique convenant préci sément à ce type d'étude .…”
