Functional Ecology, Volume 40, Issue 5, Page 1286-1298, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract The dependence on biotic pollination may constrain plant phenological responses because flowering time ultimately defines reproductive success. We proposed a local‐scale study combining long‐term phenology and experimental data to evaluate how a key functional trait—the

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 ...

Ecology and Evolution, Volume 16, Issue 4, April 2026.Conceptual representation of topographic gradients in Amazonian igapó forests. High, medium, and low igapós differ in elevation and flood duration, with low igapós experiencing the longest periods of inundation. Fungal mycelia and DNA symbols indicate sampling of root‐associated mycorrhizal communities across the gradient, used to assess the influence ...
