PL-East = Punta Laguna - East community; PL-West = Punta Laguna - West community;
*As the Punta Laguna - West community could not be included in the analysis an independent t-test was performed (see text);
Significant after applying Bonferroni's correction (see Methods);
identified as a community preferred behavior likely maintained by social learning;
ф functionally equivalent variant.
