Drought, post-dispersal seed predation and the establishment of epiphytic bromeliads (Tillandsia spp.)

Post-dispersal predation in epiphytes is poorly documented. In the course of a study on in situ germination of two Tillandsia species in a deciduous forest in Yucatan, Mexico, post-dispersal seed predation rates by the Yucatan deer mouse (Peromyscus yucatanicus) averaged 90%. Post-dispersal predation was thus more limiting than drought.附生植物的种子扩散后捕食现象鲜有文献记载。在针对墨西哥尤卡坦半岛一处落叶林中两种铁兰属（Tillandsia）植物的原位萌发研究中，尤卡坦鹿鼠（Peromyscus yucatanicus）造成的种子扩散后捕食率平均达90%。因此，种子扩散后捕食的限制作用强于干旱。
