Trait coordination reveals the fast–slow plant economics spectrum along the vertical canopy profile in central Amazonian forests

Functional Ecology, Volume 39, Issue 12, Page 3596-3610, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Understanding how environmental drivers affect tree functioning is essential to improve predictions of tropical forests' response to climate change. While functional traits directly influence tree performance, our understanding of how canopy environments shape their ...

Deciphering fire tolerance of trees at the Amazonia–Cerrado transition by trait‐based approach: Implications from species to communities

American Journal of Botany, Volume 112, Issue 10, October 2025.
Abstract Premise Understanding how fire impacts trees is essential for predicting the effects of novel fire regimes on plant diversity in the transition between the world's two most diverse biomes, the Cerrado and the Amazonia. Here we addressed knowledge gaps regarding physiological damage and mortality in transitional species within fire‐prone ...

Litter Dynamics and Nutrient Stocks in a Chronosequence of Hyperxerophilous Forest Under the Effect of Clear Felling

Ecology and Evolution, Volume 15, Issue 10, October 2025.
We investigated litter accumulation and nutrient stocks across a forest regeneration chronosequence in hyperxerophilous Caatinga following clear‐cutting. Using multivariate statistics and structural decomposition indices, we identified functional litter profiles and their association with nutrient cycling and soil resilience. Our findings highlight how

Photochemical performance and source-sink relationships in galls induced by Pseudophacopteron longicaudatum (Hemiptera) on leaves of Aspidosperma tomentosum (Apocynaceae)

Photosynthetica (Praha), 2020
The establishment of the galling insect generates a biotic stress that leads to tissue transformation. However, galls can maintain chlorophyll (Chl) and consequently photosynthesize. Herein, we evaluated the consequences of the biotic stress generated by

Indole Synthesis via Allenyl Ester; Enantioselective Total Synthesis of Geissoschizoline

ChemistryEurope, Volume 3, Issue 5, September 18, 2025.
An indole synthesis via an allenyl ester intermediate at ambient temperature has been developed. The mild reaction conditions allow the use of a broad range of substrates. Notably, the utility of this approach is demonstrated through the asymmetric total synthesis of geissoschizoline, a Strychnos‐type monoterpenoid indole alkaloid.

Antiparasitic Indole Alkaloids from and from the Peruvian Amazonia

Natural Product Communications, 2014
Twenty-three indole alkaloids were isolated from Aspidosperma desmanthum and A. spruceanum . Alkaloids 1 - 4 were isolated from the leaves, 5 - 8 from the stem bark and 9 - 15 from the root bark of A. desmanthum .
