Abstract

CALLISTO, M.; BARBOSA, F. A. R.  and  MORENO, P.. The influence of Eucalyptus plantations on the macrofauna associated with Salvinia auriculata in Southeast Brazil. Braz. J. Biol. [online]. 2002, vol.62, n.1, pp. 63-68. ISSN 1519-6984.  http://dx.doi.org/10.1590/S1519-69842002000100008.

The influence of Eucalyptus plantations on the structure and composition of macroinvertebrate communities associated with the aquatic fern Salvinia auriculata Aublet were investigated in a high altitude lake bordered by either secondary Atlantic forest or Eucalyptus plantations. Comparisons of the diversity of Chironomidae (Diptera, Insecta) larvae in the littoral zone between these two vegetation types showed higher diversity of larvae in waters bordered by Eucalyptus. The results demonstrated that the predominance of carnivorous taxa among the macroinvertebrate fauna appears to be the major controlling factor for limiting diversity in lake areas bordered by Eucalyptus.

Keywords : Chironomidae; Chironomus; macroinvertebrates; environmental impact.
