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 ...

High extinction risk of the endemic tree flora in a hyper‐diverse region of the Amazon
PLANTS, PEOPLE, PLANET, Volume 7, Issue 4, Page 998-1010, July 2025.The rapid global loss of biodiversity, especially in the Neotropics, underscores the need to understand how deforestation impacts endemic plant species' extinction risk and conservation status. Due to limited ranges and habitat specialization, endemics are particularly Vulnerable.

Global Change Biology, Volume 31, Issue 7, July 2025.This study examined soil organic carbon (SOC) and pyrogenic carbon (PyC) stocks in tropical Andean soils across elevation and disturbance gradients in Colombia. SOC stocks to 100 cm depth averaged 433.10 Mg C ha−1 while PyC was 34.13 Mg C ha−1. Key drivers of PyC stocks include soil clay (%), mean annual precipitation (PA), pH, Ca, and NDVI, which ...

Functional Ecology, Volume 39, Issue 6, Page 1537-1549, June 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract The world is experiencing a rise in global temperatures as a result of climate change. Higher temperatures along with more frequent heat waves negatively impact physiological levels and ultimately lead to plant death.

Bosques andinos del sur de Ecuador, clasificación, regeneración y uso
Revista Peruana de Biología, 2005 Existen muy pocos inventarios y descripciones sintaxonómicas de la vegetación de bosques montanos tropicales. Este trabajo presenta datos sobre los bosques del sur de Ecuador localizados en la Reserva Biológica San Francisco, límite norte del Parque Nacional Podocarpus.

Ecology and Evolution, Volume 15, Issue 5, May 2025.We aim to uncover the current and historic effective dispersal distances and characterize fine‐scale genetic structure in the forest tree species Nothofagus pumilio. Short seed dispersal distances mean N. pumilio distribution expansion capacity may be limited, especially in the context of global change.
