Flagellate protist abundance in phytotelmata of Aechmea distichantha Lem. (Bromeliaceae) in the upper Paraná river basin - doi: 10.4025/actascibiolsci.v35i4.17134

摘要: In some Bromeliaceae species the leaf sheaths form a tank or phytotelma, accumulating water and organic detritus, conditions that allow establishment of different communities. Thus, this study evaluated relationship between diameter volume in bromeliad Aechmea distichantha Lem. density flagellates found phytotelmata, as well influence hydrological periods proximity sampled strata on phytotelma patterns abundance distribution. Samplings were conducted two 2010. each sampling, four plants collected from three strata, classified according to distance river level. A one-way ANOVA identified significant differences flagellate periods. The phytotelmata was evidenced by regression analyses, lack perimeter tank. Moreover, level did not pattern abundance. our results suggested period tanks are determinant heterotrophic phytotelmata.
