Variabilidad radial física y anatómica del leño de árboles de Amburana cearensis

open access: yesColombia Forestal, 2018
Existen pocos estudios relacionados con microdensitometría de rayos X en madera de bosques tropicales nativos. Este estudio tuvo como objetivo determinar la variación radial de la densidad aparente del leño de Amburana cearensis (Allemão) A.C.Sm.

Ungulate prey availability to inform Mexican wolf recovery within its historical range

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 2, February 2026.
We estimated the potential ecological carrying capacity for the Mexican wolf based exclusively on ungulate prey biomass estimated from camera trap surveys. In the United States, the potential density estimate is high (21.4–52.7 wolves/1,000 km2) owing to the presence and relatively high densities of elk, mule deer, and white‐tailed deer.

Integrated demographic strategies are more strongly associated with variation in conspecific density dependence than single traits in tropical tree seedlings

open access: yesJournal of Ecology, Volume 114, Issue 2, February 2026.
Species‐specific conspecific negative density dependence (CNDD) varied widely among tropical tree species. CNDD was strongest in fast‐growing species and tall, long‐lived pioneers, weakly related to most functional traits except wood density and strongest in rare species. These results show that integrated life‐history strategies explain CNDD variation

Species functional traits affect regional and local dominance across western Amazonian forests

open access: yesJournal of Ecology, Volume 114, Issue 1, January 2026.
Dominant tree species in western Amazonian forests show distinct functional trait combinations linked to habitat type: conservative traits in stressful habitats and greater plant size in less stressful environments. Local dominants are defined by resource conservation strategies and widespread dominants are defined by resource acquisition strategies. A

Plant functional traits shape the provision of ecosystem services to Indigenous communities in western Amazonia

open access: yesPeople and Nature, Volume 7, Issue 12, Page 3313-3329, December 2025.
Abstract Context. Exploring how Indigenous People interact with plants through their functional traits allows us to understand the ecological bases of plant selection. Functional traits can help explain why certain plants are consistently chosen for specific purposes across diverse cultural contexts.

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 ...

Caracterización energética de la madera de Acacia pennatula Schltdl. & Cham. y Trema micrantha (L.) Blume

open access: yesRevista Mexicana de Ciencias Forestales, 2017
La biomasa de los árboles es utilizada, principalmente, como combustible sólido en las comunidades rurales para cocinar y calentar, pero también puede ser usada para producir combustible líquido y gaseoso.
