Abstract
Increasing coastal development and global warming have resulted in large-scale habitat changes, with artifi- cial coastal structures replacing extensive tracts of natural shores. In Singapore, for example, more than 63% of the natural coastline has been replaced by seawalls. Multiple studies from both temperate and tropical re- gions have compared species diversity supported by these artificial structures with natural rocky shores. Few, however, have estimated and compared the population size and movement of common intertidal species between these two habitat types. Using mark-recapture techniques, this study investigated: (1) the popula- tion size of three common gastropod genera ( Nerita s..
