    A large percentage of plant and animal diversity is concentrated in the tropics. Among these, low tropical forests occupy an important place in Mesoamerica since they are one of the ecosystems most threatened by human activity. The marked seasonality of these forests, together with pressure from humans, alters of ecological processes. Herbivory was quantified with a categorical index for precise estimations in two ravines, one conserved and the other perturbed. Two levels of study were considered: the community level and the species level with only those species common to the two ravines. Significant differences were obtained between the two ravines for the two levels of study: z=3.130 and P=0.001, for the analysis at the community level and z=2.88 and P=0.003, for shared species. The different types of anthropogenic pressure provoke alterations in ecological processes, such as herbivory, with serious consequences for the plant community.

    Keyworks: ravines, ecology, plant-animal interactions, anthropogenic pressure.
