In southeast China there is a puzzle. Pseudotaxus chienii lives as a relict, a plant that used to have a much wider geographic range. Now it’s limited to comparatively few locations. This is common for many plants that...

Genetic differentiation among varieties of a Neotropical savanna tree
The Neotropical savanna fruiting tree species, Hancornia speciosa (Apocynaceae) has high social and economic importance in Brazil. Originally classified as six botanical varieties, more recently only two have been...

The impact of floral morphology on genetic differentiation in two closely related biennial plant species
The genetic diversity and structure of plant populations are determined by the interaction of gene flow, genetic drift and natural selection. These processes are to some extent dependent on the mating system of plants...

Population genetic patterns in an endangered island perennial
Oceanic islands are of particular importance for the conservation of global diversity. Rare island plants with small population sizes and unique genetic patterns resulting from prolonged evolutionary isolation are...

Intra-species ecological divergence in irises
Speciation is often described as a continuum, from minor divergence of populations to complete reproductive isolation between species. Within-species population divergence can shed light on the first steps of speciation...

Spatial distribution of genetic variation in the flower colour polymorphic Iris lutescens
Flower colour polymorphism in plants had been used as a classic model for understanding the importance of neutral processes versus natural selection in population differentiation. Iris lutescens (Iridaceae) is a...
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...
