Advancing an interdisciplinary framework to study seed dispersal ecology
Although dispersal is generally viewed as a crucial determinant for the fitness of any organism, our understanding of its role in the persistence and spread of plant populations remains incomplete. Dispersal influences...

Orchid conservation must be guided by an understanding of their ecology
What makes orchids unique can also make saving them a challenge.

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 geographic range. Now it’s limited to comparatively few locations. This is common for many plants that...

How does mixed mating persist, when self-pollination ensures a plant won’t reproduce?
Being a seed from self-pollination guarantees failure in Eucalyptus regnans. Yet despite this, new research shows a mixed-mating system. including selfing, is evolutionarily stable.

Demographic consequences of genetic variation for a plant invasion
Genetic variation may play an important role in plant population fitness and invasion success. Li et al. combine genetic analysis and demographic data to investigate the consequences of genetic variation for the...
