|Title:||Spatial Variation In Understory Frugivorous Birds In An Atlantic Forest Fragment Of Southeastern Brazil|
|Abstract:||Between April 1999 and March 2000 we studied the understory frugivorous birds in an late sucessional stage of an Atlantic Forest fragment at the Intervales State Park, SP. Our goal was to verify the existence of spatial variation in the capture pattern of these birds, and if this variation could be explained by structural characteristics of the understory, such as fruit abundance and species richness of fruiting plants. We set up five sample unities in the study area, each one consisting of a trail with a line of six mist nets along it and two 250 m2 plots adjacent to this trail. The structure of the understory was characterized by the following descriptors: total height, bole height, circumference at breast height and frequencies of plant life forms, all of them taken inside sub-plots. Monthly, plants inside the plots were examined for the presence of ornithochorous fruits and birds were mist-netted. The capture pattern of frugivorous birds varied spatially in the study area, possibly following the spatial variation occurred in fruit production or due to the low vegetation density in the understory, at least in one of the sample unities. This study shows that understory generalist frugivorous birds can be influenced by these factors, what may ultimately affect seed dispersal and establishment of understory ornithochorous plants in the Atlantic Forest.|
