Biología stream biofilms Periphyton colonization tropical limnology Variation in the structure of the periphytic community that colonizes artificial substrata inthe Medellín river (Colombia). Weekly samples were taken from microscope glass slides attached to acrylicsubstrata were placed at subsuperficial level in two sampling stations in the higher section of the Medellín river,Colombia, from January through March 1998. Diversity and evenness varied with time (Friedman p<0.05).There were spatial differences in biomass, productivity, diversity and evenness (Friedman p<0.05). Total biomassand productivity increased with the time of colonization at station 1. Station 2, with four times more waterflow, had lower diversity and mean evenness values. During the colonization process the were 76 species (22families). The Chrysophyta, mainly diatoms, were the most abundant (56 % of the total), followed by Clorophyta(29 %), Cyanophyta (11 %) and Cryptophyta (4 %). Rev. Biol. Trop. 55 (2): 585-593.
