摘要: Detrended correspondence analysis (DCA) was evaluated for its effectiveness in displaying factors controlling the spatial distribution of benthic insects an oligotrophic stream where experimental gradient (copper) that selectively affects population abundances imposed. DCA proved to be highly sensitive differences among samples and consistently provided ecologically meaningful species ordinations.
