The distribution of plant species around the Mediterranean basin is a product of the influence of both geographical barriers and of climatic changes experienced during the Tertiary, with the transition from a warm to a...

East African traditional bananas: the resources of an understated diversity
Banana cultivation is a long tradition for numerous communities in East Africa, growing particularly the robust diploid ‘Mchare’ variety in the Kilimanjaro and the triploid ‘Mutika’ in the Great Lakes region. Since the...

Adaptation of ecological strategies to climate within species
In Grime’s C-S-R strategy model, plant ecological strategies vary between ruderals (R), stress-tolerators (S) and competitors (C). These variations are assumed to reflect adaptation of species to the environment...
Geographic population structure in an outcrossing plant invasion after centuries of cultivation and recent founding events
Population structure and genetic diversity of plant invasions are the result of evolutionary processes such as natural selection, drift and founding events. Some invasions are also molded by specific human activities...

Does the seed bank contribute to the build-up of a genetic extinction debt for grassland populations of Campanula rotundifolia?
Genetic diversity was highest in above-ground populations, though below-ground populations contained 8 % of unique alleles that were absent above-ground.
Genetic evaluation of an endemic plant from Patagonia
Oxalis laciniata is endemic to the Patagonia region of South America, inhabiting high mountains and steppe and even growing on the coast. In a recent study published in AoB PLANTS by López and Bonasora, the marked...

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...
Frequent wildfires modify genetic structure in Pinus halepensis
The recurrence of wildfires is predicted to increase due to global climate change. Budde et al. examine the population genetic effects of frequent fires in natural stands of the fire-adapted Mediterranean tree Pinus...
Origin of distribution and genetic diversity of a savanna species
Cyclic glaciations were frequent throughout the Quaternary and this affected species distribution and population differentiation worldwide. Combining ecological niche modelling and phylogeographical analysis, this study...

From South America to Shenzhen, China; road trip of an invasive weed
The South American weed Mikania micrantha has spread rapidly across Southern China since its introduction to the Shenzhen region in 1984. Geng et al. used SSR markers to investigate and map genetic diversification of...
Mixed mating after the loss of self-incompatibility in a long-living perennial herb
Flowering plants display an extensive range of adaptive floral forms, which are often correlated with their mating systems. The maintenance of contrasting strategies such as those adopted by obligate outcrossers...
Historical refugia and origins of genetic diversity in a Neotropical savanna tree species
Souza et al. investigate the role of Pleistocene climate changes in driving the geographic distribution and genetic diversity of Dimorphandra mollis, a tree species endemic to the Cerrado, the largest Neotropical...
