Wood density variation across an Andes‐to‐Amazon elevational gradient

open access: yesJournal of Ecology, Volume 113, Issue 9, Page 2370-2385, September 2025.
We study how wood density varies along a 3500‐m elevational gradient, spanning from the Andean tree line to the Amazon basin. Our results reveal that wood density decreases from low to mid‐elevations, then increases toward the tree line. These patterns underscore the influence of species composition, life forms such as tree ferns, and local ...

Physiological and Growth Responses of Tropical Dry Forest Tree Seedlings to Water and Nutrient Additions: Comparisons Between Nitrogen Fixers and Non‐Fixers

open access: yesBiotropica, Volume 57, Issue 5, September 2025.
This study examined the physiological and growth responses of tropical dry forest tree seedlings to water and nutrient additions, comparing nitrogen (N)‐fixing and non‐fixing species. The results showed that N‐fixing species responded more strongly to nutrient addition, accumulating significantly more biomass and increasing height growth rate. Overall,
