Changes in seed dispersal processes and the potential for between-patch connectivity for an arid land daisy

Emmerson, Louise; Facelli, Jose M; Chesson, Peter; Possingham, Hugh P; Day, Jemery R

Description

Dispersal is a major and critical process in population biology that has been particularly challenging to study. Animals can have major roles in seed dispersal even in species that do not appear specifically adapted to animal-aided dispersal. This can occur by two processes: direct movement of diaspores by animals and modification of landscape characteristics by animals in ways that greatly influence dispersal. We exploited the production of large, persistent dispersal structures (seed heads,...[Show more]
