Afromontane forest ecosystems share a high similarity of plant and animal biodiversity, although they occur mainly on isolated mountain massifs throughout the African continent. Kadu et al. use Prunus africana, one of...

Gene flow in mountain environments
Responses of high-mountain plant species to global change are highly influenced by the genetic background of the species, including genetic diversity or gene flow between populations. García-Fernández et al. study the...
Inbreeding and outbreeding depression in Grevillea
For many Australian plants little is known about either their population genetics or the effects on mating systems of variation in pollen transfer distances. Forrest et al. manipulate pollination of Grevillea...
Reproductive isolation and mycorrhizae in Orchis
Mycorrhizal fungi are needed for germination and seedling establishment in orchids, so associations may be involved in determining hybridization between species. Jacquemyn et al. show that in three species of the genus...
Gene dispersal in wild carrot populations
How far can a gene disperse? Historical and contemporary gene dispersal can be estimated from spatial genetic structure and paternity analysis, and Rong et al. (pp. 285–296) find that an estimate of gene flow in Daucus...
Genetic structuring in a large population of Arabidopsis
The perennial Arabidopsis lyrata is able to propagate both sexually and asexually, and this is expected to influence spatial genetic structure in the species. A fine-scale molecular study by Lundemo et al. (pp. 243–254)...
