Stemflow Dynamics in the Jamari National Forest (Brazilian Amazon): I. The Role of Tree Structure

Biotropica, Volume 58, Issue 3, May 2026.
A portion of rainfall that contacts tree canopies is drained down tree stems as stemflow. Stemflow is an underexamined component of rainfall partitioning in tropical forests. To investigate how tree canopy structural attributes influence stemflow in the Brazilian Amazon, we measured stemflow, rainfall, and dendrometric parameters of 56 trees in the ...

The Flooding Gradient Affects Seed Dispersal by Fruit‐Eating Fishes in Amazonian Whitewater Floodplain Forests

Biotropica, Volume 58, Issue 3, May 2026.
This research approaches the interaction between frugivorous fish and the flooded forests in the central Amazon. We evaluated the fruit consumption by fish and the seed dispersal potential along the flood gradient. We tested the hypothesis that the role of fish as seed dispersers varies between low várzea (LV) and high várzea (HV) forests.

Wound‐Healing Efficacy of Garcinia pedunculata Fruit Extract: In Vivo and In Silico Validation of Regenerative Mechanisms With Histological Analysis

Food Science &Nutrition, Volume 14, Issue 4, April 2026.
This study demonstrates that G. pedunculata fruit possesses potent wound‐healing activity, evidenced by accelerated wound contraction, reduced epithelialization time, enhanced fibroblast proliferation, increased collagen deposition, and improved neovascularization in both excision and burn models. ABSTRACT Garcinia pedunculata Roxb., traditionally used
