Temporal patterns of Brassicaceae diversification
Huang et al. propose that whole genome duplication events serve as a constant pump for continuous and high species diversification.
Diversification in Mediterranean firs occurred much earlier than expected
Mediterranean firs appeared millions of years earlier than was supposed, and likely through a single colonization event from Asia.
Scaly Tree Ferns Have Slow and Steady Diversification
Did the Cyatheaceae become such a diverse family slowly over time, or in spurts? The largest molecular sampling yet points to gradual accumulation of species.
Distribution of Veronica polyploids is influenced by both habitat differentiation and historic glaciation
Species with higher ploidy levels prefer cooler, wetter habitats than diploids.
Arabidopsis halleri: a model system for studying population differentiation and local adaptation
Whilst studies on Arabidopsis thaliana have generally been highly molecular and/or genetic in nature, most studies using A. halleri have addressed adaptation and variation in adaptive traits in the species’ natural habitat.
A diversity of lipid composition in the seeds and fruits of the palm family
Palms are vitally important due to their high vegetable oil production, which can occur in both fruits and seeds. The full range of lipid storage and composition, however, hasn’t been well understood across this large and diverse group.
Identifying the biodiversity of the Mayan underworld
In the caves of Quintana Roo, there are not only stalactites hanging from the ceiling. There are tree roots too, but the roots of which trees?
