Environmental morphing enables informed dispersal of the dandelion diaspore
Animal migration is highly sensitised to environmental cues, but plant dispersal is
considered largely passive. The common dandelion, Taraxacum officinale, bears an intricate
haired pappus facilitating flight. The pappus enables the formation of a separated vortex ring
during flight; however, the pappus structure is not static but reversibly changes shape by
closing in response to moisture. We hypothesised that this leads to changed dispersal
properties in response to environmental conditions. Using wind tunnel experiments for flow …
