Title A name given to the resource Zooplankton Responses In A Tropical System With Environmental Stress Creator An entity primarily responsible for making the resource Nelson Javier Aranguren Riaño, José Daniel Monroy-González Description An account of the resource Processes of environmental transformation that currently occur in the climatic change context generate changes in ecosystems and biological communities. ¿How populations respond to these stressors? ¿what effects could occur on taxonomic and ecological diversity? The taxonomic composition and structure of the zooplankton was analyzed with relationship to environmental changes in a tropical water reservoir located at 6º02`18``N and 73º29`16`` W. During four months, samples were taken weekly covering stations of low, medium, and high precipitation. A high degree of temporal variability was established, it associated with a short hydraulic retention time estimated at 8 days.  Nine species were collected, of which Keratella tropica tropica and Thermocyclops decipiens were the two most abundant and constant species. Found values of H’ diversity and S richness were considered low, corresponding to a little mature community associated with a fluctuating physical environment and supported by high variation coefficients of electrical conductivity and Sechhi disk transparency. Drastic variations on the system volume in short time lapses generate important changes in the physical expression of system with a direct effect on composition and structure of the zooplankton. In general, the response model of the zooplankton in the reservoir according to the statement by the intermediate disturbance hypothesis.    RESPUESTAS DEL ZOOPLANCTON EN UN SISTEMA TROPICAL CON ALTA TENSIÓN AMBIENTAL   Los procesos de transformación ambiental que se dan en la actualidad, en un marco de cambio climático, generan modificaciones en los ecosistemas y comunidades biológicas, ¿Cómo responden las poblaciones a estos factores de tensión? ¿Qué efectos se darían sobre la diversidad taxonómica y ecológica? Se analizó la variación de la composición taxonómica y estructura del zooplancton en función de los cambios ambientales en un reservorio tropical ubicado a 6º02`18``N y 73º29`16`` O.  Semanalmente se realizaron muestreos en la zona limnética del sistema durante cuatro meses que abarcaron los periodos seco, de transición y de alta precipitación. Se estableció un  alto grado de variabilidad temporal asociada al poco tiempo de retención hidráulica estimado en 8 días. Se registraron 9 especies, entre ellas Keratella tropica tropica y Thermocyclops decipiens  que fueron las más abundantes y constantes. Los valores de diversidad H´ y riqueza S hallados se consideran bajos, lo que corresponde a una comunidad poco madura vinculada a un ambiente físico fluctuante, evidenciado en los elevados coeficientes de variación de la conductividad eléctrica y la transparencia Secchi. La fluctuación del volumen del sistema en lapsos cortos de tiempo, genera cambios significativos en la expresión física del sistema con efecto directo sobre la composición y estructura del zooplancton.  En general el modelo de respuesta del zooplancton en este reservorio, se ajusta a los supuestos de la hipótesis de disturbio intermedio.
