Article
Pollen and seed dispersal are key processes affecting the demographic and evolutionary dynamics of plant species, and are also important considerations for the sustainable management of timber trees. Through direct and indirect genetic analyses we studied the mating system and the extent of pollen and seed dispersal in an economically-important tim...
Article
Full-text available
Mating system and gene flow are major influencing factors of species population dynamics and evolution. These factors are often not characterized in tropical tree species, yet they constitute basic information that must be considered to implement sustainable management practices. In particular, as logging implies a reduction of the density of conge...
Article
Full-text available
Owing to the reduction of population density and/or the environmental changes it induces, selective logging could affect the demography, reproductive biology and evolutionary potential of forest trees. This is particularly relevant in tropical forests where natural population densities can be low and isolated trees may be subject to outcross pollen...
Article
ABSTRACT Aim Phylogeographical signatures of past population fragmentation and demographic change have been reported in several African rain forest trees. These signatures have usually been interpreted in the light of the Pleistocene forest refuge hypothesis, although dating these events has remained impracticable because of inadequate genetic mark...
Article
Full-text available
The evolutionary events that have shaped biodiversity patterns in the African rainforests are still poorly documented. Past forest fragmentation and ecological gradients have been advocated as important drivers of genetic differentiation but their respective roles remain unclear. Using nuclear microsatellites (nSSRs) and chloroplast non-coding sequ...

Conference Paper
Background The refuge hypothesis is often invoked for explaining the spatial structure of species diversity (SSDS) in central African rainforests. However, the present-day SSDS could also result from environmental filtering and stochastic processes. Thus, species distributional data are not sufficient for inferring the role of biogeographical facto...
