“…Los arroyos de la región pampeana se caracterizan por la ausencia de vegetación riparia, por bajas velocidades de corriente y por ser receptores de una cantidad elevada de efluentes industriales y domésticos (Feijoó and Lombardo 2007). En la zona Metropolitana del Gran Buenos Aires, la población y las industrias se concentran alrededor de tres cuencas de caudal considerable y de gran superficie: Matanza-Riachuelo, Reconquista y Luján.…”

“…Las concentraciones de materia orgánica (estimada según las DBO y DQO), nutrientes, OD y la abundancia de bacterias coliformes superaron los valores establecidos en la legislación argentina para proteger la vida acuática (SRHN 2005). El efecto de la polución orgánica y la eutrofización son determinantes de las diferencias existentes entre arroyos pampeanos (Feijoó and Lombardo 2007). Estos arroyos están sujetos a variaciones fuertes en sus concentraciones de fósforo y de material particulado (Rodríguez Castro 2015;Ranieri 2015) a causa de las fluctuaciones estacionales y las precipitaciones (Feijoó et al 1999).…”

“…The streambed consists of fine sediments (primarily silt and clay) without stones or pebbles (Feijoó et al, 2014). Besides, even in the upper-stream reaches, the absence of riparian vegetation, results in high levels of irradiance along the course, favoring the development of dense macrophyte stands and phitoperiphyton growth (Feijoó & Lombardo, 2007). Moreover, the heterogeneity of the pampean streams, resides not in the different types and sizes of the substrates present but rather in the diverse architecture of the aquatic plants which shelter a rich and dense invertebrate community .…”

“…However, high nutrient levels have been reported for these streams even in sites with low or moderate cattle-raising and agriculture Iheringia, Série Zoologia, Porto Alegre, 105(2):228-234, 30 de junho de 2015 (Feijoó et al, 1999;Bauer et al, 2002). The occurrence of high nutrient concentrations is characteristic of pampean streams (Feijoó & Lombardo, 2007). Indeed, nutrient levels in stream water show a relatively high concentration when compared with other lotic systems of the world (Feijoó et al, 2014).…”

“…According to Parodi (1942) the intense competition of the grasses for water in periods of rainfall deficit would have impeded the establishment of hardwood trees within the region. Even in the upper-stream reaches, the absence of riparian vegetation, results in high levels of irradiance along the course, favoring the development of dense macrophyte stands and accompanying algal growth (Feijoó & Lombardo, 2007).…”
