Spatial distribution of brachyuran crabs in Sarawak with emphasis on fiddler crabs (Genus UCA) as biomonitors of heavy metal pollution
This study consisted of intertidal surveys to determine the general distribution and zonation of intertidal Brachyuran crabs along the coast of Sarawak and investigations into the use of fiddler crabs (genus Uca) as a biological monitor for heavy metal pollution. The suitability of fiddler crabs as...
