Distribution of Veronica polyploids is influenced by both habitat differentiation and historic glaciation

Species with higher ploidy levels prefer cooler, wetter habitats than diploids.

Resprouting potential of rhizome fragments in an invasive aquatic plant

Non-native aquatic Ludwigia species from a polyploid complex are among the world’s most problematic invasive plants. A new paper in AoBP finds out why.

The Miscanthus sacchariflorus homeland lies beneath the waves

A study of the genetic diversity of Miscanthus sacchariflorus has revealed that the centre of its diversity now lies under the Yellow Sea.

Role of ploidy in Arabidopsis arenosa colonization of alpine habitats

Doubling the chromosomes of Arabidopsis arenosa does not always lead to strong ecological niche differentiation.

The morphometrics of autopolyploidy: insignificant differentiation among sexual–apomictic cytotypes

Polyploidization of the plant genome affects the phenotype of individuals including their morphology. In autopolyploids, we expect mainly nucleotypic effects, from a number of...

A new biological species in the Mercurialis annua polyploid complex

In eastern Spain (and many other places if you look) you can find Mercurialis annua, a plant with a complicated sex life. A new...

Phylogenetic relationships of two endemic eyebright species from the eastern European Alps

Mountain ranges host a considerable number of endemic species, which is considered to be the result of the complex origin of mountain ranges, shaped...

AoBP special issue announcement: Population differentiation in plants

Plant populations continually change over space and time. Many factors contribute to this differentiation with some resulting in evolutionary change. Unravelling the relative importance...

Sexuality and apomixis in Hieracium are tightly associated with ploidy

Asexual reproduction via seeds (apomixis) is an important speciation mechanism in angiosperms, but its frequency is largely unknown. Mráz and Zdvořák used flow cytometric...

Identifying evolutionary patterns in complex plant groups with DNA barcoding

The sequencing of short standardised pieces of DNA (DNA barcodes) is commonly used to tell species apart. This approach is thought to be of...

X-ray dose limits for microscopy lower than we thought

Subtle damage to hydrated tissue occurs at a far lower dosage than previously thought, and may be difficult to recognize.

Habitat partitioning through reproductive interference in Geranium

We’re familiar with seeing insects flit from one flower to the next, carrying pollen as they do so. What happens when they...

Improving overyielding in legume-based mixtures

A major challenge when supporting the development of intercropping systems remains the design of efficient species mixtures. The ecological processes that sustain...

The Oaks of the North Are Unexpectedly Well-Defended

Normally you would expect plant defences to increase, the closer you get to the equator. This is where insect life is more...
