A study of Arenaria provincialis's (Caryophyllaceae) geographic range finds that despite its narrow distribution it has a high level of molecular variation.

Population genetics of purple saxifrage (Saxifraga oppositifolia L.) in the high Arctic archipelago of Svalbard
The genetic characteristics of species impact their capacity to maintain populations and colonize new areas, and the presence of genetic diversity is especially important for plant populations in highly stochastic...

Genetic diversity and conservation of the Canarian Flora (Review)
Canarian endemic plants are phylogenetically constrained by the traits of the colonizing lineages, although also influenced by distances to the mainland.
Genetic structure and diversity of Coffea
In addition to the two species cultivated for coffee, Coffea arabica and C. canephora, the genus has a further 123 wild species, of which 112 are native to Africa and the Indian Ocean islands. Razafinarivo et al. assess...
Genetic connectivity and evolution in Crepis
Islands play a central role in the study of plant evolution in the Mediterranean. Mayol et al. analyse the impact of varying patterns of habitat occupancy on genetic diversity and structure in Crepis triasii, an endemic...
Manioc marriage mystery unearthed
Echoing Forrest Gump’s famous box of chocolates quote (number 40 in the American Film Institute’s Top 100 movie quotes), you never really know what to expect when you get married. Well, certainly in some parts of Africa...

Progenitor–derivative speciation in Pozoa
Progenitor–derivative speciation occurs when an isolated peripheral population diverges from the ancestral condition and forms a derivative species. López et al. find evidence of this type of speciation in the genus...
Biased morph ratios and skewed mating success
In distylous plant species, skewed morph ratios are not uncommon and may arise from a range of factors such as demographic stochasticity and leakage of the heteromorphic incompatibility system. Meeus et al. study...
Progenitor–derivative speciation in orchids
Sexually deceptive Ophrys orchids attract specific pollinators, and shifts in these pollinators may drive speciation with a progenitor–derivative pattern. Schlüter et al. find evidence for such a scenario in an east...
