bird pollination in an angraecoid orchid on reunion island (mascarene archipelago, indian ocean).although numerous angraecoid orchids in madagascar display typical sphingophilous syndrome (i.e. white, nectariferous, long-spurred flowers, producing a strong scent at the crepuscule that is attractive to moths), three species of angraecum in reunion, belonging to the endemic section hadrangis, have atypical unscented and short-spurred flowers. the aim of the study was to investigate the implication of plant-pollinator interaction on the evolution of floral morphology of these peculiar island f ...200616554310
the geographic scale of diversification on islands: genetic and morphological divergence at a very small spatial scale in the mascarene grey white-eye (aves: zosterops borbonicus).oceanic islands provide unique scenarios for studying the roles of geography and ecology in driving population divergence and speciation. assessing the relative importance of selective and neutral factors in driving population divergence is central to understanding how such divergence may lead to speciation in small oceanic islands, where opportunities for gene flow and population mixing are potentially high. here we report a case of genetic and morphological structure in the mascarene grey whit ...201020504327
investigating the role of the melanocortin-1 receptor gene in an extreme case of microgeographical variation in the pattern of melanin-based plumage pigmentation.the réunion grey white-eye (zosterops borbonicus) is a single-island endemic passerine bird that exhibits striking geographically structured melanic polymorphism at a very small spatial scale. we investigated the genetic basis of this color polymorphism by testing whether the melanocortin-1 receptor (mc1r), a gene often involved in natural melanic polymorphism in birds, was associated with the observed plumage variation. although we found three non-synonymous mutations, we detected no associatio ...201223227219
