Composition and dynamics of allochthonous organic matter inputs and benthic stock in a Brazilian stream
Riparian vegetation provides the nutrient and energy input that maintains the metabolism and biodiversity in tropical headwater streams. In the present study, it was hypothesised that ∼30% of riparian plant species contribute over 70% of coarse particulate organic matter and, because tropical plants...

Riparian vegetation provides the nutrient and energy input that maintains the metabolism and biodiversity in tropical headwater streams. In the present study, it was hypothesised that ∼30% of riparian plant species contribute over 70% of coarse particulate organic matter and, because tropical plants are perennial and semi-deciduous, it was expected that leaf fall would occur year round. The aims of the present study were to evaluate the composition and structure of the plant riparian zone and the input and associated benthic stock of organic matter. The riparian vegetation was composed of 99 taxa. The most abundant plant species were Tapirira obtusa, Sclerolobium rugosum, Croton urucurana, Byrsonima sp. and Inga sp.

The biomass contributed monthly by the vegetation ranged from 28 ± 6 g m-2 to 38 ± 11 g m -2, and the mean monthly benthic standing stock was 138 57 g m -2.
