  1. Data are from two zones (mudflat and saltmarsh) in three locations in Argentina, from north to south: Mar Chiquita (MCH); San Antonio Oeste (SAO) and Riacho San José (RSJ) from two environmental conditions in the saltmarsh zone of MCH: tidal situation previous and after flooding. The number in each bristle board denotes the percentage of site fidelity crabs and within the parentheses the total number of individuals tagged on the corresponding day
