Vertical stratification of bat assemblages in flooded and unflooded Amazonian forests

摘要: Tropical rainforests usually have multiple strata that results in a vertical stratification of ecological opportunities for animals. We investigated if this influences the way bats use space flooded and unflooded forests Central Amazon. Using mist-nets set canopy (17 to 35 m high) understorey (0 3 we sampled four sites upland (terra firme), three seasonally by nutrient-rich water (varzea), nutrient-poor (igapo). rarefaction curves found species richness were very similar. An ordination analysis clearly separated bat assemblages from those both habitats. Gleaning carnivores associated with understorey, whereas frugivores abundant strata. Of frugivores, Carollinae some Stenodermatinae specialists, but several Steno- dermatinae mostly used canopy. The first group mainly includes that, general, feed on fruits shrubs, second figs other fruits. conclude communities occurs even within lower heights, such as Amazonian forests, distribution is closely related their diet foraging behaviour (Current Zoology 56 (4): 469-478, 2010).
