Soil Properties and Plant Species Identity Independently Influence Arbuscular Mycorrhizal Fungal Composition Across Lowland Tropical Forests

Biotropica, Volume 58, Issue 2, March 2026.
We found that plant species identity and soil properties, especially soil phosphorus availability, independently structured arbuscular mycorrhizal fungal (AMF) community composition in tropical forests across central Panama. We also found that soil nutrient availability may mediate the interaction networks between plants and AMF. ABSTRACT Plant species

Interspecific variation in leaf phenology and its relationship with plant traits in a seasonal tropical forest

Functional Ecology, Volume 40, Issue 2, Page 433-450, February 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Leaf phenology plays an important role in plant life‐history strategies and in determining ecosystem‐level fluxes of carbon and water. In seasonal tropical forests, leaf phenology is highly variable among tree species, but limited quantitative data have hindered our ...

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

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 ...
