亚洲象Elephas maximus是唯一在非洲进化的象属（Elephas）物种。5-6 2000万年前迁移到欧亚大陆（Sukumar 2003）。亚洲象是仅存的几种巨型动物之一（Owen-Smith 1988），已经从c.其历史范围的95%（Sukumar 2006）。亚洲象吃水果时，它是可用的，排便完整的种子，其中一些后来发芽的粪便（Lekagul & McNeely 1977，Ridley 1930）。然而，到目前为止，还没有详细的研究亚洲象的食果性和种子传播（Corlett 1998）。据报道，亚洲象吃的水果的唯一共同特征是它们的体积相对较大，但没有证据表明它们是任何植物物种的唯一传播者（Corlett 1998），与更食果的非洲森林象Loxodonta africana cyclotis相反（Babweteera等人，2007年，Chapman等人，1992年，科克伦2003年，Feer 1995年）。
The Asian elephant Elephas maximus is the only living species of the genus Elephas (Elephantidae) that evolved in Africa c. 5–6 million y ago and migrated into Eurasia (Sukumar 2003). The Asian elephant is one of the few remaining extant megafauna (Owen-Smith 1988) and has disappeared from c. 95% of its historical range (Sukumar 2006). Asian elephants eat fruit when it is available, defecating intact seeds, of which some later germinate in the dung (Lekagul & McNeely 1977, Ridley 1930). However, to date there has been no detailed study of frugivory and seed dispersal by Asian elephants (Corlett 1998). The only common feature of the fruit reported to be eaten by Asian elephants is their relatively large size, but there is no evidence that they are exclusive dispersers of any plant species (Corlett 1998), in contrast to the more frugivorous African forest elephants, Loxodonta africana cyclotis (Babweteera et al. 2007, Chapman et al. 1992, Cochrane 2003, Feer 1995).
