Using organelle markers to elucidate the history, ecology and evolution of plant populations
Species-area relationships explained by the joint effects of dispersal limitation and habitat heterogeneity.
It is suggested that heterogeneous habitat and dispersal limitation are two predominant mechanisms for maintaining the spatial distributions of the species in these two forests.
The large‐X effect in plants: increased species divergence and reduced gene flow on the Silene X‐chromosome
Evaluating the role of the X‐chromosome in the speciation of two closely related plant species – the white and red campions (Silene latifolia and S. dioica) – that hybridize widely across Europe demonstrates that the X-linked genes show a very small and insignificant amount of interspecific gene flow, while gene flow involving autosomal loci is significant and sufficient to homogenize the gene pools of the two species.
Neutral theory in macroecology and population genetics
This work critically discusses opportunities and theoretical challenges in neutral macroecology, particularly in regard to effective community size, ecological drift, community differentiation and ecological dominance.
Hubbell's fundamental biodiversity parameter and the Simpson diversity index
This work developed an analytical relationship between this biodiversity parameter and the well-known Simpson diversity index, which suggests that diversity patterns of the metacommunity can also be equally described by the Simpson index.
On estimation of the ratio of pollen to seed flow among plant populations
The effects of contrasting patterns of gene flow for different plant genes on their population structure under isolation by distance, on Nei's genetic distance measure, on divergence in nucleotide sequence between populations and on gene phylogenies are explored.

Species Diversity in Local Neutral Communities
It is demonstrated that the local species diversity patterns converge to that of the metacommunity as the size of the embedded local community increases, and a simple relationship exists between the fundamental diversity parameter of neutral theory and Simpson’s index for local communities.
