Effect of the Fleshy_fruits Eating Birds on Seed Dispersal.

Lu Changhu, Chang Jiachuan ( Northeast Forestry University, Harbin 150040).  
Frugivorous birds can be divided into two groups: dry_fruits and Fleshy_fruits eating birds. Fleshy_fruits eating birds swallow the whole fruit and consume the pulp. Seeds are vomited or excreted wholly and dispersal. There are some characteristics of seeds spatial pattern during dispers process. Germination ratio of seeds through birds digestive system may be increased. Many factors affect on birds' selection of fruits. Co_adaption exists in many aspects between birds and birds_dispersed plants. Mild toxins often exist in fruit, which may prevent birds from over_eating a time in one place. Future study would be in two directions: seed dispersal ecology and eco_chemistry in seed dispersal.
