dc.description.abstractOrnithochorous fruits make up an important part of the diet of birds and many studies have related the different morphological types of fruits with the choice by birds. We analyzed the intrinsic characteristics of plants and how human impact can affect this choice. Through analyses of covariance we related the degree of human pressure in each study site (high or low) and the morphological characteristics of 57 ornithochorous species with visiting rates and consumption of fruits by birds. We did not find any intrinsic plant characteristic (life form, size and type of diaspore) that explains the rates of consumption and visit by birds. On the other hand, the degree of human impact affected directly the mutualism between plants and birds. Plant species located in areas that suffer high human pressure had number of visits and consumption rates 3,3 and 3,5 lower than plants located in pristine areas, respectively. The negative consequences of the reduction of consumption of fruits in areas with high human pressures may directly affects the interactions between birds and plants and the regeneration of the ornithochorous species.en
