摘      要：The probability and pattern of secondary seed dispersal by dung beetles(Scarabaeinae)depend on their community structure and composition at the site of primary deposition,which,in turn,seem to be strongly determined by ***,we expected pronounced differences in secondary seed dispersal between forest and savanna in the northern Ivory Coast,West *** found 99 dung beetle species at experimentally exposed dung piles of the olive baboon(Papio anubis(Lesson,1827)),an important primary seed disperser in West ***-six species belonged to the roller and tunneler guilds,which are relevant for secondary seed *** species showed a clear habitat *** to the Neotropics,species number and abundance were much higher in the savanna than in the *** and tunnelers each accounted for approximately 50%of the individuals in the savanna,but in the forest rollers made up only 4%.Seeds deposited into the savanna by an omnivorous primary disperser generally have a higher overall probability of being more rapidly dispersed secondarily by dung beetles than seeds in the ***,rollers disperse seeds over larger *** contrast to other studies,small rollers were active in dispersal of large seeds,which were seemingly mistaken for dung *** results suggest that rollers can remove seeds from any plant dispersed in primate dung in this ecosystem.
