Macrobenthic sampling of a transect of six stations on the North coast of Central Java in October 1985 revealed three distinct communities which can be regarded as paraliels of those from north temperate waters: (i) An Amphioplus (Lymanella) laevis/Lovenia sp. community parallel with the Amphiura chiajei/Brissopsis lyrifera community. (ii) A Tellinides timorensis community parallel with Tellina spp. communities. (iii) A Laciolina philippinarum community parallel with Macoma spp. communities. A strict comparison of the structure of the first two of these communities with their counterparts in England shows that within-habitat diversity is similar in both regions. Diversity at two shallower subtidal stations is higher than at two deeper stations: this is attributed to the effects of natural, low-level, physical disturbance which maintains the communities in a sub-climax stage. Total abundance and biomass of the macrobenthic fauna was lower at the Javanese stations than in their temperate counterparts. [ABSTRACT FROM AUTHOR]
