Abstract
In two streches of the Itaúna stream, one in a gallery forest and the other in an herbaceous vegetation zone, litter matter input (sorted by leaves, ligneous and reproductive components) were measured during a year. In the gallery forest stretch, the direct input and lateral transport attained 713 g.m-2.year-1 and 421 g.m-1. year-1, respectively. In contrast, the herbaceous vegetation stretch showed a direct litter input and lateral transport of only 86 g.m-2.year-1 and 124 g.m-1. year-1, respectively. The empoverishment of riparian vegetation had a significant effect on the decrease of allochthonous input to stream mainly by direct input. Peaks of direct input into Itaúna stream occurred during late dry season and in the early wet season. They were attributed to leaf fall from riparian trees and to enviromental conditions, such as wind. In March, which was the rainy season in this region, a peak of lateral transport was observed mainly in the herbaceous vegetation stretch, probably induced by runoff.
A introdução de serapilheira (separada em folhas, galhos e partes reprodutivas) foi medida, durante 1 ano, em dois trechos do Córrego Itaúna, um em zona de mata galeria e outro em zona de vegeta��ão herbácea. No trecho circundado por mata de galeria, a entrada direta e por transporte lateral atingiu 713 g.m-2.ano-1 e 421 g.m-1.ano-1, respectivamente. Por outro lado, no trecho circundado por vegetação herbácea, obteve-se valores de entrada direta de serapilheira e transporte lateral de somente 86 g.m-2.ano-1 e 124 g.m-1.ano-1, respectivamente. O empobrecimento da vegetação ripária teve um efeito significativo na diminuição da entrada alóctone para o curso d’água principalmente por via direta. Ocorreram picos de entrada de serapilheira para o Córrego Itaúna no final da estação seca e começo da estação chuvosa, atribuídos à queda de folhas das árvores ripárias e às condições ambientais, como vento. Em março, foi observado um pico de transporte lateral principalmente no trecho de vegetação herbácea, provavelmente devido ao escoamento superficial.
