| The aim of the study was to verify the temporal variation of allochthonous material input into a stream, and which structures contribute to the organic material pool, as well as to analyze the occurrence of macroinvertebrates associated with the litter. Samples were taken from October, 2004 to October, 2005 in two transects along the riparian zone. At each transect, three sampling stations were chosen. At each one, submersed and suspended collectors (1.5 m above bottom) were installed. Input and retention of coarse benthic organic material were analyzed and classified as flowers and diaspores, (seeds and fruits) and vegetative structures (leaves and branches). There were no statistical differences between input of material in suspended and submersed... |
