dc.description.abstract	The distribution patterns of benthic algal assemblages in the Tinto, Odiel and Piedras rivers were analyzed during the winter of 2005 in 18 sampling stations. The main objective was to assess and compare the algal communities and parameters affecting them both in the zones affected by acid mine drainage (AMD) and in naturally alkaline waters. A total of 108 benthic diatom taxa and 31 non-diatom taxa were identi ed. Results showed large differences between algal communities in the two environments: Pinnularia acoricola, P. subcapitata and Eunotia exigua were the most frequent diatom taxa in regions affected by acid mine drainage, along with algae like Klebsormidium and Euglena mutabilis were the most relevant non-diatom taxa. In alkaline waters the dominant diatom taxa were Planothidium frequentissimum, Gomphonema angustum, Fragilaria capucina, and some species of Navicula (N. viridula, N. veneta or N. radiosa), accompanied by Oscillatoria and Anabaena as well as by streptophytes of the group of zygnemataceae and desmidiaceae
dc.description.abstract	Se han analizado los patrones de distribución de las comunidades algales bentónicas en los ríos Tinto, Odiel y Piedras, sumando un total de 18 estaciones de muestreo visitadas durante el invierno de 2005. El objetivo principal ha sido evaluar y comparar las comunidades algales y los parámetros que las afectan tanto en zonas in uenciadas por el drenaje ácido como en las zonas libres del mismo. Se han identi cado un total de 108 taxones de diatomeas bentónicas y 31 taxones de otras algas. Se observaron grandes diferencias en las poblaciones de productores primarios en ambos tipos de ambientes: Pinnularia acoricola, P. subcapitata y Eunotia exigua fueron las diatomeas más frecuentes en los ambientes afectados por el drenaje ácido, acompañadas por algas como Klebsormidium y Euglena mutabilis. En las aguas alcalinas las diatomeas dominantes fueron Planothidium frequentissimum, Gomphonema angustum, Fragilaria capucina y algunas especies de Navicula (N. viridula, N. veneta o N. radiosa), acompañadas por Oscillatoria y Anabaena y estreptótos del grupo de las zygnematáceas y de las desmidiáceas
