| Abstract |
|
Testudinidae Geochelone yniphora The endemic Madagascar tortoise Geochelone yniphora exhibits a very localised distribution in the vicinity of Baly Bay on the northwest coast of the island. Data on growth, feeding, activity patterns, and habitat preference relate to adaptations in a strongly seasonal (wet-dry), tropical climate. Current distribution and density data indicate that G. yniphora is on the verge of extinction. This endangered status can be attributed to: (1) commercial exploitation in the past; (2) current heavy predation by the African bush pig; and (3) continuing habitat modification by indigenous agriculturists who create and maintain anthropogenic savannas through annual burning.
