Figure 8. Grazing on halimeda incrassata branches with terminal 

 segments that were approximately 20 hr old (new) versus 

 branches with terminal segments that appeared several days 

 old (old). Vertical bars throught the histograms show +1SE. 

 On 19 of the 37 ropes, herbivores removed all of both plants 

 (2 ropes) or none of either plant (17 ropes); these 

 replicates were excluded from Wilcoxon Paired-Sample Test 

 since they provided no information on the relative 

 susceptibility of new versus old branches. The sample size 

 used to generate the p-value in the figure was thus 18.
