Burrow morphologies, crab characteristics and soil properties in different seasons across intertidal areas of a restored mangrove forest

This work analysed burrow morphologies, crab characteristics and soil properties across intertidal areas of a restored mangrove forest. Burrows were larger in monsoon, occupied by the juvenile crabs, but smaller in summer, occupied by adults. The burrows were longer and deeper with increasing soil m...

Description
Summary:This work analysed burrow morphologies, crab characteristics and soil properties across intertidal areas of a restored mangrove forest. Burrows were larger in monsoon, occupied by the juvenile crabs, but smaller in summer, occupied by adults. The burrows were longer and deeper with increasing soil moisture. Burrowing crabs were abundant in Avicennia, and their female population was high in open mudflat. Sesarmids were pre-dominant in Rhizophora while fiddlers in Avicennia, but only fiddlers were present in open mudflat. This work suggested to maintain soil moisture and mudflat across intertidal mangrove areas, for managing the crab functionality in restored mangrove habitats. •This workanalysed burrow morphologies in relation to crab and soil characteristics across the intertidal zones of a restored mangrove forest.•The burrow morphologies were significantly greater during monsoon, occupied by the juvenile crabs of smaller size and weight.•This work suggested to maintain open gaps across intertidal areas and to monitor soil moisture in restored mangroves for better crab functionality.
