Relationships between rotifers, phytoplankton and bacterioplankton in the Corumbá reservoir, Goiás State, Brazil
Abstract
This study evaluates the relationships between rotifers and phytoplankton and rotifers and bacterioplankton in a tropical reservoir. Fourteen stations in the reservoir were sampled, including in its arms and tributaries, in the dry and rainy seasons. The highest rotifer density was found in the dry season, mainly in the upper and intermediary stretches of the reservoir. Brachionus calyciflorus, Polyarthra vulgaris, Keratella tropica, K. cochlearis, K. americana and Pompholyx complanata were the most abundant species. Densities of B. calyciflorus and bacteria were significantly correlated. On the other hand, there was an inverse relationship between P. vulgaris and bacteria. Diatoms (Bacillariophyceae) were observed to be associated to K. americana. We suggest that the rotifer populations play a part in microbial and herbivory food webs.
