DISTINGUISHING Campa guianensis Aubl. FROM Campa procera D.C. (MELIACEAE) BY MORPHOLOGY OF YOUNG SEEDLINGS [PDF]

open access: yesActa Amazonica, 1995
Seedling morphology was studied in Campa guianensisAubl. and Carapa proceraD. C. from germination to 90 days age. In both species germination is hypogeal and cryptocotylar. Both have rare albino seedlings.

Design, Physicochemical Characterization, and Antibacterial Activity of Freeze‐Dried Sodium Alginate Sponges Loaded With Amazonian Oil (Carapa guianensis Aubl.) and a Mn(II)‐Phenanthroline Complex for Potential Use in Topical Applications

open access: yesChemistry &Biodiversity, Volume 23, Issue 7, July 2026.
ABSTRACT This study reports the development of freeze‐dried sodium alginate sponges containing Amazonian andiroba oil (Carapa guianensis Aubl.) and [Mn(phen)2Cl2], aiming to obtain porous biomaterials with antibacterial activity for potential topical wound applications. X‐Ray diffraction revealed predominantly amorphous structures for all sponges (AA1,

Stomatal Decoupling From Photosynthesis Under High Temperatures Is Consistent With Stomatal Optimisation

open access: yesGlobal Change Biology, Volume 32, Issue 7, July 2026.
Many leaf gas exchange models predict that photosynthesis and stomatal conductance are tightly coupled and respond in parallel to changing environmental conditions. However, experiments show that when temperatures increase beyond the thermal optimum of photosynthesis, stomatal conductance may continue to rise while photosynthesis declines, facilitating

Compositional Characterization, Quality Parameters, and Physicochemical and Bioactive Properties of Pequi ( Caryocar brasiliense ) Oils From Xingu and Cerrado in Mato Grosso, Brazil

open access: yesJournal of the American Oil Chemists' Society, Volume 103, Issue 6, Page 609-622, June 2026.
Cerrado oil is richer in MUFA and antioxidant compounds, while Xingu oil shows higher SFA and enhanced oxidative stability, reinforcing the potential of pequi oil as a sustainable bioactive ingredient. ABSTRACT Pequi ( Caryocar brasiliense ) is a native fruit widely distributed in Brazilian biomes, specially in Cerrado, known for its high oil yield and

Development of species distribution models helps identify source country anomalies in timber supply chains

open access: yesEcosphere, Volume 17, Issue 4, April 2026.
Abstract For many timber species, a lack of consistent, comprehensive global distribution data makes validating supply source (country of harvest) difficult. To supplement these data, we developed species distribution models (SDMs) for the American mahogany species (genus Swietenia) to demonstrate how SDMs can assist in the analysis of supply sources ...

Animal–Plant Interactions Under Defaunation: Consequences for Amazonian Trees of Commercial Interest

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
We experimentally investigated the effects of medium‐ and large‐sized mammal defaunation on the removal and fate of seeds from economically important forest species in Amazonian forests. Our results show that mammal exclusion significantly reduced seed removal, although the magnitude of this effect varied among plant species.
