Abundance data of 66 macroinvertebrate morphospecies (columns) living on 75 stones (rows) of a stream in southeast Brazil. Stones were around 20 cm diameter and were sampled from downstream (pedra1) to upstream (pedra75) direction. Consecutive stones are spaced 1-6 m. Details can be found in Melo & Froehlich (2001).
