Interspecific competition in germination of bird-dispersed seeds in a habitat with sparse tree vegetation in South Africa.

Results Germination trials: bird-ingested vs manually depulped seeds The comparisons of the germination rate between the bird-ingested and the manually depulped seeds were highly significant for the tree/shrub species (Wald χ 2 = 142.9, df = 3, P < 0.001; Fig. 3 ).
