Evolutionary history of Pseudotaxus: old lineage, young populations

In southeast China there is a puzzle. Pseudotaxus chienii lives as a relict, a plant that used to have a much wider...

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...

The impact of floral morphology on genetic differentiation in two closely related biennial plant species

The genetic diversity and structure of plant populations are determined by the interaction of gene flow, genetic drift and natural selection. These processes are...

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...

Intra-species ecological divergence in irises

Speciation is often described as a continuum, from minor divergence of populations to complete reproductive isolation between species. Within-species population divergence can shed light...

Spatial distribution of genetic variation in the flower colour polymorphic Iris lutescens

Flower colour polymorphism in plants had been used as a classic model for understanding the importance of neutral processes versus natural selection in population...

Gene dispersal in wild carrot populations

How far can a gene disperse? Historical and contemporary gene dispersal can be estimated from spatial genetic structure and paternity analysis, and Rong et...

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...
