The hidrologic characteristics of this lotic systerm<br />were also investigated in order search for biotic and abiotic interactions. From February:<br />1999 to January 2000, samples from two Iocalities were taken monthly and subjected to<br />physicochemical and biological analysis. The most important famlies were<br />Chironomidae (Diptera), Baetidae (Ephemeroptera) and Hydropsychidae (Trichoptera)<br />Both the physicochemical and biological characteristics of this ecosystem are rainfall<br />pattern dependent.</p>}, number={12}, journal={Tecné, Episteme y Didaxis: TED}, author={Ruiz Chavarro, María Victoria and Rincón Hernández, María Eugenia}, year={2002}, month={jul.} }
