Canopy structure and conifer dominance in rainforests
Globally, conifer dominance is restricted to cold and nutrient-poor habitats, probably due to competition for light with angiosperms. Aiba et al. use a ground-based,

Hydrochoric gene flow in invasive riparian Impatiens
Riparian systems are prone to invasion by alien plant species, which may be facilitated by hydrochory, the transport of seeds by water.
