Contrasting Phylogenetic Signals in Flowering and Fruiting Phenology at Species and Assemblage Scales in a Climbing Plant Community

Journal of Vegetation Science, Volume 36, Issue 6, November/December 2025.
This study examined the phylogenetic conservatism of flowering and fruiting in 78 climbing plant species relative to environmental gradients in a South Brazilian forest. Although species‐level analysis found a weak phylogenetic signal, a strong influence was detected at the assemblage scale, revealing that evolutionary history mediates the phenology ...

Endophytic fungi associated with Araucaria angustifolia (Bertol.) Kuntze

Anais da Academia Brasileira de Ciências
The diversity of endophytes and their ecological relationships with the endangered conifer Araucaria angustifolia (a critically endangered species) are unrevealed. This study aimed to characterize the diversity of endophytic fungi associated with A. angustifolia.

O cultivo da araucária para produção de pinhões como ferramenta para a conservação

Pesquisa Florestal Brasileira, 2012
A madeira da araucária (Araucaria angustifolia  (Bertol.) O. Kuntze) teve grande importância econômica no Brasil, principalmente entre 1930 e 1970. O desmatamento ocasionou a redução drástica do tamanho populacional de araucária e atualmente ela integra ...

Aerial sketchmapping for monitoring forest conditions in Southern Brazil. [PDF]

, 2015
Aerial sketchmapping is a simple, low cost remote sensing method used for detection and mapping of forest damage caused by biotic agents (insects, pathogens and other pests) and abiotic agents (wind, fire, storms, hurricane, ice storms) in North America.

Tall stature and small leaves: ecological strategies that enhance tree growth across the subtropical Brazilian Atlantic Forest

Oikos, Volume 2025, Issue 8, August 2025.
Ecological strategies reflect the mechanisms used for species to sustain a population. Predicting plant growth in ecological communities is crucial, especially with climate change impacting ecosystem functioning. By employing a large dataset for the subtropical Brazilian Atlantic Forest (BAF), we evaluated whether species' relative growth rates (RGR ...

Density of Araucaria angustifolia wood from overstocked stand

Pesquisa 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.

BIOMASSA E CARBONO ORGÂNICO EM POVOAMENTOS DE Araucaria angustifolia (Bertol.) Kuntze

Ciência Florestal, 2015
The objective was to estimate the biomass and organic carbon in Araucaria angustifolia stands with different ages. The Araucaria angustifolia stands studied were not pruning but were thinning in difference ages.
