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.

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 of ecological and genetic...

How repeatable is microevolution on islands?
Archipelagos provide a valuable framework for investigating phenotypic evolution under different levels of geographical isolation. García-Verdugo et al. analysed two co-distributed, widespread plant lineages to examine...

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 differentiation. Iris lutescens (Iridaceae) is a...

Style morph frequencies in tristylous Lythrum
A balance between stochastic processes and negative frequency-dependent selection largely determines style morph frequencies in heterostylous populations. Costa et al. investigate variation in morph frequencies at the...
Genetic variation, habitat destruction and survival
Habitat destruction and fragmentation affects genetic variation by reducing the size and increasing the isolation of populations.

Adaptive and neutral variation in Psilopeganum sinense
Natural selection and genetic drift are important evolutionary forces in determining genetic and phenotypic differentiation in plant populations.
Gene flow, drift and populations of Sardinian Aquilegia
The Mediterranean Basin is an important region for plant biodiversity, but there are relatively few studies of fine-scale genetic variation. Garrido et al. assess the spatial genetic structure of all known locations of...
Genetic connectivity and evolution in Crepis
Islands play a central role in the study of plant evolution in the Mediterranean. Mayol et al. analyse the impact of varying patterns of habitat occupancy on genetic diversity and structure in Crepis triasii, an endemic...
