Abstract

Ruminant-mediated seed dispersal, an understudied process in tropical forests, was examined via Phyllanthus emblica–Axis axis interaction. A captive Axis deer regurgitated intact P. emblica seeds after retaining them in the rumen for 7–27 h. At Rajaji National Park, a considerable fraction (22%) of deer-regurgitated P. emblica seeds germinated, although lower than unconsumed seeds (72%). The size and strength of seeds like P. emblica might ensure that ruminants regurgitate them intact instead of defecating them.
