This study suggests an effect of temporal variation on the capture of mangrove crabs by pitfall traps. More crabs, and less consistently, more species were captured during a period with rainfall than a dry period. These results have important implications for methods used to sample mangrove crabs that are dependent on the activity of crabs such as pitfall traps, visual counts and hand-catches. Future studies that use these methods need to consider the effect of weather on the catchability of crabs and take into account these effects when interpreting data.
