Distribution of Functional Traits Along Climatic Gradients in the Subtropical Atlantic Forest

open access: yesAustral Ecology, Volume 50, Issue 11, November 2025.
We assessed the correlation between climatic factors and altitude with the spatial distribution of tree functional traits in the Subtropical Atlantic Forest. Deciduousness, symbiotic fixation of nitrogen (SNF), toothed leaf, spinescence and leaf area were more significantly associated with climatic drivers.

Density of Araucaria angustifolia wood from overstocked stand

open access: yesPesquisa Florestal Brasileira, 2016
The aim of this work was to evaluate the radial and longitudinal variations of wood specific gravity in an overstocked stand of Araucaria angustifolia, with 65 years. The stand was located in the National Forest of Açungui, Campo Largo, Parana State, Brazil, with thinning recorded between 1970 and 1980, without subsequent thinnings.
