Fig. 2. DCA ordination of species assemblages at survey sites in three different elevational zones along the longitudinal gradient of the Portuguesa River, Venezuela: Camaguan, 50-100 m (open squares); Middle, 100-150 m (filled circles); and Upper, 150-200 m (open triangles). The three regions were significantly different in assemblage composition (MANOVA, p <0.0001).
