| বিবরন: | Weekly samples were taken from microscope glass slides attached to acrylic substrata 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 bio-mass and productivity increased with the time of colonization at station 1. Station 2, with four times more water flow, had lower diversity and mean evenness values. During the colonization process the were 76 species (22 families). The Chrysophyta, mainly diatoms, were the most abundant (56 % of the total), followed by Clorophyta (29 %), Cyanophyta (11 %) and Cryptophyta (4 %). |
