PROGRAMAS DE SECAGEM PARA MARUPÁ (Simarouba amara), PARÁ-PARÁ (Jacaranda copaia) E VIROLA (Virola surinamensis)

FLORESTA, 2013
Um programa de secagem é uma indicação, para cada espécie e espessura, das condições ambientais necessárias dentro da câmara de secagem convencional, que equilibram as taxas de secagem com a formação de defeitos. Entre as metodologias para a elaboração de programas de secagem, destacam-se aquelas baseadas em equações empíricas cuja variável ...

Marked tree demographic variation along subtle elevation differences partially explains species' habitat associations in an Amazonian forest

Journal of Ecology, Volume 113, Issue 10, Page 2860-2874, October 2025.
These findings show that even small differences in elevation can lead to biologically meaningful variation in resource access that translates into significant differences in tree growth and survival. However, resource access could not fully explain the patterns of topographically driven demographic variation we observed. While certain species may still

Tree crown architecture: a tool for decay resistance evaluation [PDF]

, 2013
The variability of natural durability contributes to the bad perception of some wood end-users. In our search, we need to adjust our methods and strategies to estimate natural durability and extract higher value from wood resources.

Evaluation of Yield, Chemical Composition and Antioxidant Capacity of the Essential Oil From Leaves and Fruits (Seed and Bark) of Virola sebifera Aubl. (Myristicaceae)

Flavour and Fragrance Journal, Volume 40, Issue 5, Page 892-904, September 2025.
In the study of V. sebifera plant organs, the leaves exhibited the highest EO content, with peak production in February, the Amazonian winter. Notably, among the various plant parts yielding EO, the fruit peel contained the highest oil concentration. ABSTRACT The essential oils (EOs) of Virola sebifera were obtained from leaves, seed fruits and husked ...

Anthropogenic disturbances simplify frugivory interactions in Amazonia

Oikos, Volume 2025, Issue 7, July 2025.
Frugivory interactions are essential ecological processes for the regeneration of tropical forests, ensuring ecosystem resilience following disturbances. However, little is known about how frugivory interactions are shaped by anthropogenic disturbances, especially in Amazonia – one of the most biodiverse ecosystems on Earth.
