Phylogeography of the invasive Brazilian peppertree in South Africa
Can a better understanding of the origins of the invasive tree species Schinus terebinthifolia in South Africa help to inform its management?

A hybridisation headache hinders control of invasive Prosopis species
Can large scale biogeographic studies provide insights into Prosopis genetic diversity, hybridisation and clarify taxonomic uncertainties?
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...

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...
Conservation genetics and niche shift estimates of the endemic and vulnerable Viola cheiranthifolia
Alpine oceanic ecosystems are considered amongst the most ephemeral and restricted habitats, with a biota highly vulnerable to climate changes and disturbances. As an example of an alpine insular endemic, Rodríguez...
Establishing the cell biology of apomixis in Boechera
The genus Boechera (Brassicaceae) is comprised of both sexual and apomictic species, permitting comparative analyses of meiotic disturbances and parthenogenesis. Hybridization, polyploidy and environmental adaptation...
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.

The evolutionary processes of apomictic brambles
Asexual reproduction is relatively common in higher plants and comprises vegetative reproduction or clonal reproduction through seeds (apomixis or agamospermy). Apomixis is found in less than 1% of angiosperms and...
Spontaneous hybridization in wild roses
A propensity to form polyploid hybrids is a peculiar feature of roses. Herklotz and Ritz investigate the population genetics of forty five mixed stands of dog roses across Central and South-Eastern Europe using...
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...

High levels of genetic diversity and population structure in an endemic and rare species: Implications for conservation
The analysis of genetic structure and variability of isolated species is of critical importance in evaluating whether stochastic or human-caused factors are affecting rare species. Low genetic diversity compromises the...
Introgression, genetic and morphological variation in sympatric oaks at the edge of their range
Historical and ongoing hybridization between the oak species Quercus petraea and Q. robur leads to difficulty in identifying the taxonomic status of individual trees. Despite this, Beatty et al. using genetic and...
Geographic distribution of the two cytotypes of Alnus glutinosa in Europe
Polyploidy in plants has been studied extensively. In many groups, two or more cytotypes represent separate biological entities with distinct distributions, histories and ecology. Mandák et al. analysed ploidy level...
