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

open access: yesBiotropica, 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.

Findings From the Pearl River Basin: Dissolved Oxygen Dominates Functional Trait Filtering and Diversity Patterns in Urban Rivers

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Urbanization reshapes fish communities via environmental filtering. Surveying 44 sites across an urban (Huadi) and a relatively natural (Zengjiang) river in the Pearl River Basin (2024), we linked environmental variables to fish functional traits using RLQ and SEM, finding that dissolved oxygen is the dominant filter in urban reaches—selecting low ...
