Note

A patch of Halodule wrightii Aschers in the Indian River, Florida, was clipped near the sediment surface and a mirrored prism was set in place to photographically record subsequent regrowth of blades in situ. Tagging was considered not feasible. After a lag time of 1–3 days, mean blade length increased rapidly (up to 8.5 mm day−1) for several days. As older blades began to mature and their growth rate slowed down, the average growth rate of all blades decreased. Within 21 days the standing stock had been completely replaced, and the clipped plot was indistinguishable from a control plot.
