Macro-infaunal diversity and assemblage in the mangrove habitat of Lawas, Sarawak, Malaysia

The diversity and composition of macrofaunal communities are important components to understand the mangrove ecosystem structures and functions. To understand the seasonal distribution of macro-infaunal community and diversity, this study was conducted from July 2019 to February 2020 in the intertid...
