We investigated if this stratification influences the way bats use the vertical space in flooded and unflooded forests of theCentral Amazon. Using mist-nets set in the canopy (17 to 35 m high) and in the understorey (0 to 3 m high) we sampled four sitesin upland unflooded forests (terra firme), three in forests seasonally flooded by nutrient-rich water (varzea), and three in forestsseasonally flooded by nutrient-poor water (igapo). Using rarefaction curves we found that species richness in the understorey andcanopy were very similar. An ordination analysis clearly separated the bat assemblages of the canopy from those of the understorey inboth flooded and unflooded habitats. Gleaning carnivores were clearly associated with the understorey, whereas frugivores wereabundant in both strata. Of the frugivores, Carollinae and some Stenodermatinae were understorey specialists, but several Stenodermatinaemostly used the canopy. The first group mainly includes species that, in general, feed on fruits of understorey shrubs,whereas the second group feed on figs and other canopy fruits. We conclude that vertical stratification in bat communities occurseven within forests with lower canopy heights, such as Amazonian seasonally flooded forests, and that the vertical distribution ofbat species is closely related to their diet and foraging behaviour.展开更多

The distribution of hibernating bats was analysed in five selected zones designated Ⅰ-Ⅴ. These zones have a similar relative humidity, diverse temperature ranges inside the system, as well as air flow rates. A multi-year research programme highlighted the relationships between the occurrence of hibernating bats of various species and the microclimate of these particular zones. What is of essential importance are the sites with an air flow in their zones exceeding 0.02 m·s^-1, then is temperature and humidity. The air flow determines more intensive settling of wintering bats (zones Ⅲ, Ⅳand Ⅴ). The zone Ⅱ-tourist zone with periodic air flows and often visited by humans is the least used by hibernating bats.展开更多
