FIGURE 1. The study area, (a.) Plan of the sand spit shows areas sampled during the mobile phase (A, B, C, D) and areas sampled during the immobile phase (1, 2, 3, 4, 5) (not drawn to scale), (b.) Cross section of the sand spit shows the distribution of vegetation and the relationship between tide levels and activity areas of Uca pugilator (not drawn to scale). The marks stood up best when placed near the posterior margin and could be seen clearly from a distance of five meters after three months. No modification of behavior was noted in marked crabs either immediately after release or during subsequent mobile activity phases. Immediate dispersal of the marked among unmarked members of the herd was observed in every case. Processing the catches always left ample time for dispersal into the mob before return to the burrows was triggered by the rising tide. Samples were taken during the mobile phase on seven consecutive days- October 2 through 8, 1970—at the same relative time of the second or daylight tidal cycle. Data for the Lincoln Index were drawn from captures of those marked the previous day. while continuing mark-recapture data over the entire.
