(A) Percent fusion vs. time, species differences. For comparable extents of fusion, L. pictus requires higher calcium concentration than S. purpuratus. The data were collected using a sample time of 0.02 (L. pictus) and 0.1 (S. purpuratus) s. (B) Rate, d(%fusion)/dt vs. time in the continued presence of calcium. The maximum rate of fusion is larger and occurs earlier in L. pictus compared with S. purpuratus. The data were low-pass filtered with a 1.0 Hz cutoff frequency before calculating the derivative using third order forward differences.
