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.

Shifting Trends in Tropical Ecology Research Over Six Decades

Biotropica, Volume 58, Issue 3, May 2026.
We analyzed over 170,000 tropical ecology publications (1960–2023) using a large language model to extract study location and biome information at scale. We show that research has grown across all biomes but is increasingly dominated by forests, with grassy ecosystems declining in relative representation and strong geographic concentration in a small ...

Cenozoic Time Constraints on the Evolution of a Gleysol‐Ferralsol‐Podzol Toposequence, Northwest Amazon Basin, Brazil

European Journal of Soil Science, Volume 77, Issue 3, May–June 2026.
ABSTRACT Deciphering the time milestones of clay formation is crucial for modeling the evolution of major geological systems near the Earth's surface. In the present study, kaolinite samples collected along four vertical profiles within a Gleysol‐Ferralsol‐Podzol soil toposequence near São Gabriel da Cachoeira, NW Amazon Basin (Brazil) are dated using ...

N‐Acetylcysteine Reduces Alveolar Bone Loss and Mitigates Systemic Oxidative Damage in Rats With Apical Periodontitis

International Endodontic Journal, Volume 59, Issue 5, Page 890-902, May 2026.
ABSTRACT Aim This study aimed to evaluate the effects of N‐acetylcysteine (NAC) supplementation in apical periodontitis (AP) induced in rats. Methodology Eighteen male Wistar rats were randomly assigned to three groups: control, AP, and AP plus NAC.

Incorporation of Kombucha Bacterial Cellulose to Produce Tomato Leathers via Cast‐Tape Drying

Journal of Food Process Engineering, Volume 49, Issue 5, May 2026.
Tomato leathers containing kombucha bacterial cellulose (KBC) were produced by cast‐tape drying. The incorporation of KBC changes the drying time of tomato leathers by cast‐tape drying. Tomato leathers containing KBC had antioxidant properties and consumer acceptability similar to tomato leather without KBC.
