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

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

Post-dispersal, epiphyte seed predation is poorly documented. Our study on the in situ germination of two Tillandsia species in a deciduous forest in Yucatan, Mexico showed an average post-dispersal seed predation rate by the Yucatan deer mouse (Peromyscus yucatanicus) of 90%. Post-dispersal predati...

Zusammenfassung:Post-dispersal, epiphyte seed predation is poorly documented. Our study on the in situ germination of two Tillandsia species in a deciduous forest in Yucatan, Mexico showed an average post-dispersal seed predation rate by the Yucatan deer mouse (Peromyscus yucatanicus) of 90%. Post-dispersal predation was thus more limiting than drought.
