Análise do efeito de borda com foco na distribuição da araucaria angustifolia

Abstract

The Araucaria angustifolia, also known as araucária or Paraná pine, is a native species of the southern region of Brazil, of great ecological, social, and economic importance. However, it faces threats due to the drastic reduction of its area caused by the conversion of forests for agricultural and livestock activities, as well as logging. The preservation of Araucaria and the Mixed Ombrophilous Forest (FOM) depends on conservation units (CUs), such as the Caçador National Forest. This study analyzes the impacts of edge effects on the abundance and size of Araucaria angustifolia in an FOM region, considering different types of matrices. The results reveal that temperature, humidity, and the surrounding matrix affect the species, which shows resistance to edge effects. Its presence in conservation areas is crucial for maintaining biodiversity and ecosystems, highlighting the importance of understanding its behavior to develop effective conservation strategies.
