Bioecological aspect of Trichoptera from the Carrizal Stream (Boyacá, Colombia)
Main Article Content
In this work, the community structure of Trichoptera and its spatial distribution along an altitudinal gradient at the Carrizal stream located on the Iguaque Sanctuary (Boyacá, Colombia) was studied. Monthly determinations of physical and chemical parameters were registred from September 1994 to October 1995 in order to establish the biotic and abiotic relationships. The community consisted of 15 genera belonging to nine families. The most important genera of caddisflies found were Ochrotrichia (28%) and Contulma (17.8%), Helycopsiche (13.4%), and Mortoniella (9.49%). The physical-chemical and biological characteristics of the Carrizal stream is dictated by the rainfall pattern. This lotic ecosystem can be considered as oligotrophic, due to limited levels of nitrogen and phosphorus, low conductivity, and quantity of suspended solids.
