On the basis of geographic and geological differences, rates of precipitation, and given the lack of basic data on the aquatic
ecology, the structure and dynamics of the phytoplankton of the high mountain lakes of the Andean cordilleras, the present study
develops limnological aspects of the paramo lakes of Colombia taking the following research problems into account: Are there
differences in phytoplankton composition of the lakes of the humid tropical Andes? What relationships are there between
the phytoplankton structure and the physical and chemical aspects of the paramo lakes of Colombia? Do the periods of
precipitation confer a sufficient seasonal variation on the physical and chemical variables of the lake to lead to a seasonal change in phytoplankton? What are the main features of the relation between the biochemical processes in the lakes and the change of phytoplankton species? This study is the result of a joint effort by numerous institutions and individuals. It arose in response to the need, in principle, to know about and understand processes that take place within paramo lakes, such as productivity, biomass, trophy state, nutrient cycle, and variables integrated into climatic and biochemical change of the lacustrine system. The high mountain aquatic ecosystems that are the subject of this study lie far from the centers that generate science and technology and also
represent forgotten areas that are depressed by unequal actions in the social and economic field. Consequently, comparing and contrasting the basic ecological characteristics of 20 paramo lakes of the Colombian cordilleras, although it was not an easy task, was a gratifying one.
