Figure 4. Change in width (X+1SE) of newly forming segments of 

 Halimeda incrassata as a function of time of day. Since 

 multiple branch tips on one plant could not be considered 

 indpendent replicates, we considered the mean width of tips 

 on each plant a replicate. Plots are thus based on the 

 average segment width per plant.
