The phytotelmata and foliage macrofauna assemblages of a bromeliad species in different habitats and seasons

摘要: Abstract.  1. The macrofauna living inside the phytotelmata or on foliage of bromeliads could be directly affected by habitat and seasonality. Habitat may also have indirect effects affecting plant morphology. 2. In Chaco forests, a facultative epiphytic bromeliad (Aechmea distichantha) shows different morphology when growing in sun shade conditions. Therefore, abundance assemblage composition this were analysed habitats seasons. 3. Sun plants shorter, had higher tank water content, but lower litter mass than ones. Phytotelmata temperature pH similar between habitats. 4. In phytotelmata, richness per plant, as well total richness, among seasons. Detritivores more abundant predators all Shade proportion detritivores spring summer, not winter. 5. On foliage, winter. There no differences habitats, species plants. In was for shade, whereas ants The hunting spiders summer. 6. Our study showed that mainly affects bromeliad-foliage macrofauna, macrofauna.
