Testudinidae The genus Manouria comprises two species of threatened and unusual tortoises, believed to represent primitive chelonian stock. Manouria emys is the largest mainland Asian tortoise and inhabits mid-elevation mountainous wet forest from Myanmar through peninsular Malaysia and parts of Indonesia. Manouria impressa occurs, at times sympatricaly, in upper elevation forests in mainland Southeast Asia. In this paper I discuss aspects of the ecology and behavior of the two species based on some of the of most detailed field research conducted. Wanchai et al. (manuscripts submitted) have documented patterns of diet, ranging and nesting in M. impressa in Phu Luang Wildlife Sanctuary in northernmost Thailand. Wanchai (2009) had earlier studied diet and ranging in a population M. emys phayrei in Kaeng Krachan National Park in southwestern Thailand. Both species of Manouria prefer moist forested habitat and are often found sitting in streams. Both are active mainly during rainy months and M. impressa in particular appears to spend substantial periods of the year in active, buried under leaf litter. M. impressa includes a high percentage of mushrooms in its diet. M. e. phayrei also feeds on mushrooms as well as Alocasia sp. and a variety of leafy plants, and during the bamboo growth season will ascend mountain slopes to feed on new bamboo shoots. Both species build mound nests, in some cases exceeding 30 cm in height. The paper discusses aspects of the evolutionary ecology of the genus Manouria in light of these reported patterns of behavior in the wild.
