- W2186695980 abstract "espanolSe muestrearon cinco humedales de Bogota (Guaymaral, Jaboque, Juan Amarillo, Santa Maria del Lago y Tibanica) y un humedal rural (Meridor, municipio de Tenjo) cuatro veces durante los periodos climaticos seco, lluvioso y de transicion (entre 2007 y 2008). Se midieron las variables fisicoquimicas y se obtuvieron muestras de perifiton para evaluar la comunidad de diatomeas. Se establecieron valores de contaminacion para cada especie de diatomeas y se calculo un indice de estado limnologico para valorar la calidad ecologica de los humedales. De acuerdo con el estado limnologico establecido, los seis humedales se pueden clasificar de la siguiente manera: Santa Maria del Lago, Meridor y Jaboque presentan condiciones limnologicas pobres a moderadas; Tibanica estan en condiciones pobres; Guaymaral tiene condiciones malas a moderadas; y Juan Amarillo tiende a presentar malas condiciones permanentemente, lo que indica que es el humedal mas contaminado. El indice propuesto fue util para clasificar los humedales dentro de diferentes condiciones limnologicas y representa adecuadamente la calidad ecologica de los humedales de Bogota. EnglishFive wetlands in Bogota (Guaymaral, Jaboque, Juan Amarillo, Santa Maria del Lago and Tibanica) and one rural wetland (Meridor, Tenjo municipality) were sampled four times during dry, rainy and transitory climatic periods (between 2007 and 2008). Physico-chemical variables were measured and periphyton was sampled to evaluate the diatom community. The pollution value per taxon (PVT) was established for each diatom species and a periphytic diatom index for Bogota Wetlands (PDIBW) was calculated to evaluate the ecological quality of the wetlands. According to the limnological status thus established, the six wetlands can be classified as follows: Santa Maria del Lago, Meridor and Jaboque exhibit poor to moderate limnological conditions; Tibanica is in poor condition; Guaymaral has severely impaired to moderate conditions; and Juan Amarillo tends to present permanent severely impaired conditions, which indicates that it is the most polluted wetland. The index proposed was useful to classify the wetlands according to their limnological status, and it adequately represents the ecological quality of the Bogota wetlands." @default.
