Abstract: This study evaluated the influence of rainfall amount on the abundance, species richness, and species occurrence and abundance distribution of the ciliate community associated with the bromeliad Aechmea distichantha. The plants were collected from a rock wall of about 10-km long at the left bank of Paraná River. We assessed the effects of both spatial and temporal variables on the community attributes, as well as whether plants geographically closer have a similar abundance distribution and species composition… Show more

“…Some amoeba species are known to outcompete flagellates after rewetting due to faster recovery rates (Geisen et al ) and could thus be the more dominant group in lower elevations at the beginning of the wet season when our experiment was conducted. Distinct effects of hydrological periods in structuring parts of bromeliad inhabiting communities have been observed previously (Buosi et al ).…”

“…Also, it has been observed that abundance of mosquito larvae, which function as a predator on microfauna, decreases with elevation (Eisen et al ). Previous studies have investigated certain effects on the community structure in phytotelmata separately, concluding that different abiotic factors, such as hydrological period (Buosi et al ), exposition to sun (Lopez and Rios , Carrias et al ) and water temperature (Kratina et al ), as well as resource concentration (Petermann et al ) and predation (Addicott , Kitching ) can affect species richness and/or (relative) abundance. Here, we transplanted bromeliad‐inhabiting microfauna between bromeliad pairs from the lower to the upper half of the elevational gradient and vice versa to study the effect of changing environmental conditions.…”
