Periphyton as indicator of non-point pollution: the case of upper basin of the Reconquista river (Buenos Aires, Argentina). Periphyton in the upper basin of the Reconquista River was studied in orderto identify the species that compose and analyze possible changes in its structure due to diffuse pollution from agricultural activities. Six samplings were carried out between December 2006 and May 2008 atintervals of three months in eight reaches adjacent to areas where agricultural and cattle farming activities are developed. Significant differences between the two types of activity were found applying similarity analysis between communities being higher the concentration of chlorophyll-a and lower the autotrophy indexes in agricultural areas. A total of 158 species per reach were found with highly variable species richness (at least 10 species and 67 species maximum). Neither an outstanding dominance by any of the species nor among diversity estimated by Shannon index were found at all sites. The conclusion was that the presence of Ulnaria ulna and Gomphonema parvulum was associated with agricultural sites whereas Nitzschia palea, Raphidiopsis mediterranea and Trachelomonas sp3 were associated with cattle farming. Se estudió el perifiton de la cuenca superior del río Reconquista con el objetivo de identificar las especies que lo componen y analizar las posibles modificaciones en su estructura debidas a la contaminación difusa provocada por las actividades agropecuarias. Se realizaron entre diciembre de 2006 y mayo de 2008 seis muestreos a intervalos de tres meses en ocho tramos adyacentes a campos dondese desarrollan actividades agrícolas y ganaderas. Aplicando análisis de similitud entre comunidades se encontraron diferencias significativas entre ambos tipos de actividad siendo más alta la concentraciónde clorofila-a y menores los índices de autotrofia en zonas agrícolas. Se contabilizaron un total de 15 especies con una riqueza específica muy variable (mínimo 10 especies y máximo 67 especies) portramo. No se encontró una marcada dominancia por parte de alguna de las especies ni en la diversidad estimada por el índice de Shannon en todos los sitios. Se concluye en cuanto a la composición específicaque la presencia de Ulnaria ulna y Gomphonema parvulum se asocia a sitios agrícolas mientras que Nitzschia palea, Raphidiopsis mediterranea y Trachelomonas sp3 a sitios ganaderos.
