LAND SNAIL DIVERSITY IN A SQUARE KILOMETRE OF TROPICAL RAINFORST IN SABAH, MALAYSIAN BORNEO

We surveyed the land snail fauna in a single square kilometre of undisturbed tropical rainforest on acidic soil in the Danum Valley Conservation Area, Sabah, Malaysian Borneo. A malacofauna assessment protocol developed for a Cameroonian rainforest (de Winter & Gittenberger, 1998) was adapted to the present study.
