RODRIGUEZBARRIOS, JAVIER  e  OSPINA, RODULFO. Retention of Coarse Particulate Organic Matter in a Stream Tropical Mountain. Bogotá, Colombia. Acta biol.Colomb. [online]. 2007, vol.12, n.2, pp.33-46. ISSN 0120-548X.

Retention percentage of three fractions of coarse particulate organic matter (MOPG) and discharge effect over retention of particulate organic matter (MOP) were studied during five months in three sectors of a tropical mountain stream, at Eastern hills of Bogotá Colombia. The tropical condition of the system, showed a pattern of constant discharge although could be a different period from low and high discharge. Results showed as average value of retention percentage was high, with a negative association between flow magnitude and percentage of retention for each MOPG fraction, being more evident in small particles (rs=0.74, p
