Resumen
The aim of this study was to describe some architectural models and study their behavior in
vegetation structure, allometric patterns and their growth dynamics to support management
activities and conservation of tree species in seasonal forest of Santa Maria (RS). In the first
chapter a descriptive analysis was performed of the species present in the fragment and its
architectural models. A list of 53 species of tree flora of a Subtropical feasonal forest in Santa
Maria (RS), distributed in 45 genera and 28 families in the local flora gifts inventoried. In the
second chapter a study of the species and the behavior of architectural models were performed
in the vertical structure of the community. When an association was detected between species
and their architectural models with vertical forest strata. The natural disturbances in the
architecture of the forest as the formations of gaps provide explanations for the persistence of
species with irregular distribution in the vertical structure of the Forest. In the third chapter of
the mechanical designs of architectural models have been studied and have been selected
among a few variables, which best explain the increase in basal area of individual trees in the
remaining. The variables that best explained the increase in basal area of trees were diameter
at breast height, crown diameter and salience index, and the architectural models of
categorical variable increased the efficiency of regression. The study of vegetation dynamics
from the behavior of groups of species of architectural models are promising for planning
activities of forest ecosystems.
