[Vertical stratification and host preference by vascular epiphytes in a Chiapas, Mexico, cloud forest].

The high diversity of vascular epiphytes in neotropical montane forest has been explained as the result of vertical stratification of the forest and specific relationships between epiphytes and their hosts trees at local scales. In a lower montane cloud forest, we studied the vertical stratification and host preferences of vascular epiphytes in a 0.0625 ha plot where 41 trees > or = of 10 cm DBH were sampled during 12 months in 2001 and 2002.
