We analyzed relations among phytoplankton and total bacterioplankton fractions in threelentic ecosystems (Neusa and Prado dams, and Fúquene lagoon) with different physicochemical characteristics,in the Andes of Colombia. Samplings were made in three sites of each water body during three surveys. Neusadam (meso to oligotrophic) had the lowest bacterial concentration; Prado dam (eutrophic) had a high bacterialand algal abundance, and the Fúquene lagoon (mesotrophic) had lower concentrations of phytoplankton but ahigh relative concentration of bacteria, probably because of its particular conditions: high organic matter and lownutrient levels in the water. There was a negative correlation of total bacterioplankton with the phytoplankton(Pearson=-0.4479, p=0.019, n=27) and a positive correlation between phytoplankton and heterotrophic bacteria(Pearson=0.3866, p=0.062, n=24) and between total bacterioplankton and DBO5 (Pearson=0.4088, p=0.034,n=27). Apparently, total bacterioplankton and phytoplankton were not coupling, but cultivable bacteria and thephytoplankton had some degree of relationship. Rev. Biol. Trop. 55 (1): 135-146.
