Abstract
Ovassiminea brevicula (Pfeiffer) (Assimineidae: Gastropoda) was oneof the most abundant and representative benthic invertebrates in the SamutSongkhram mangrove swamp, Thailand. It lived mainly in the mangrove forest with high average densities ranging from 44 to 340 snails·m-2and abundant in the sites where much litter, dead branches and seedlingswere present. Average shell length in the mature forest ranged from 4.73to 5.74 mm (range: 2.26–8.30 mm) and size structures showeddifferent patterns among the stations. In the seaward mudflat, O. breviculaappeared immediately after the saplings of Avicennia alba Blume1826 were planted. Thereafter, its densities increased with the growth of A. alba trees, probably due to provision of favourable microhabitats underthe canopies. In the mudflat with only small saplings and outside the canopyof the young forest 2 years after planting, mean shell lengths were 3.45 and3.19 mm respectively. Under the canopy of the young forest, however,mean shell length was 4.34 mm with a few larger snails. Three cohortswere separated for snail populations in the mature forest and larval recruitmentseemed to occur from February to May.
