Abstract:
We investigated changes in diversity and density of testate amoebae in epiphytes of trees in tropical montane rain forests of<br/>
southern Ecuador. Local ? microscale [height on tree trunk of 0 (base of tree trunk), 1 and 2 m; TH I, TH II and TH III, respectively] and<br/>
regional ? macroscale (forests at 1000, 2000 and 3000 m) changes were investigated. At the macroscale diversity and density of testate<br/>
amoebae peaked at 2000 m. At the microscale diversity reached a maximum at TH I, whereas density reached a maximum at TH III. The<br/>
percentage of empty shells at the macroscale was at a maximum at 2000 m and at the microscale at TH I, whereas the percentage of live<br/>
cells was at a maximum at 3000 m and at TH III. The diversity of testate amoebae in epiphytes found in the present study was high (113<br/>
species). However, only two to nine species were dominant representing 54?85 percent of total living testate amoebae. The results suggest<br/>
significant variations in density and diversity of testate amoebae at both the micro- and macroscale. However, for testate amoebae density<br/>
the macroscale appears most important whereas changes in diversity are more pronounced at the microscale.
