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