Complex evolution in an East Asian Magnolia species
Genetic incongruence hints at either ancient hybridization or incomplete lineage sorting.

How a conifer spread between isolated mountain-tops: the demographic history of Podocarpus latifolius/milanjianus
Were there land-bridges in the past that enabled trees to travel from mountaintop to mountaintop?

Where do all the Epipactis orchids come from?
Botanists use the orchid genus Epipactis as a model for speciation, but unravelling its family tree has been difficult.

Effect of climatic fluctuations of the Quaternary on xeric flora
Quaternary glaciations strongly affected the distribution of species from arid and semi-arid environments, as temperature drops were accompanied by strong fluctuations in rainfall. In this study, Ossa and colleagues...
The hidden diversity of Pitcairnia lanuginosa
Pitcairnia lanuginosa might look similar wherever you find it in South America, but hidden inside are some differences that can tell a tale about its past.

Patterns of mtDNA variation reveal complex evolutionary history of a relict and endangered peat bog pine
Assessments of eco-evolutionary mechanisms that shape the genetic structure of populations are important to understand the influence of environmental changes on plant ecosystems.In recent years, molecular markers...
Phylogeography of an Endangered Disjunct Herb: Long-distance Dispersal, Refugia, and Colonization Routes
Current diversity patterns are influenced by both historic and recent environmental conditions. Quaternary glacial cycles appear to have had a consistent role in shaping the genetic diversity and structure of plant...
Expansive reed populations – alien invasion or disturbed wetlands?
In southern Africa a pattern of Phragmites spp. reed expansion has occurred in recent decades that has shown a similar trend to cryptic invasions reported in North and South America. A recent Editor’s Choice...

Diversification of Dioon in the Mexican transition zone
The Mexican transition zone originated from the overlap of the Nearctic and the Neotropical biotas. By analysing the genetic variation within the cycad genus Dioon, a relict Neotropical group, Gutiérrez-Ortega et al...

Origins and domestication of the olive
The olive, Olea europaea (Oleaceae), is an iconic species in Mediterranean agriculture yet its origin is complex. Besnard et al. review the literature on the timeline of Mediterranean olive evolution and discuss the...
Island fragmentation and colonisation drove diversification of Aegean Nigella
Island organisms are generally understood to diverge through geographical (allopatric) speciation. This paradigm, however, might be too simplistic for continental islands that were connected with each other and/or the...
The Mediterranean cradle of Anthoxanthum diploid diversity
The Mediterranean region has cradled the evolution of many European plant taxa, including grass genera. Chumová et al. use a multidisciplinary approach combining sequence data, rDNA FISH, climatic niche characterization...
Genetic diversity and evolution of arbuscular mycorrhizal fungi in Arachnitis uniflora
Arachnitis uniflora is a mycoheterotrophic plant that obtains nutrients via arbuscular mycorrhizal fungi of neighbouring autrotrophic plants. Some mycoheterotrophic plants have the ability to associate with more than...
