Limnology and Oceanography, Volume 70, Issue 10, Page 2858-2871, October 2025.Abstract The partial pressure of carbon dioxide (pCO2) in rivers is influenced by carbonate weathering, soil CO2, photosynthesis, and the mineralization of dissolved organic carbon (DOC). In tropical regions, elevated temperatures intensify these processes. However, their seasonal dynamics remain poorly understood in large karst‐draining rivers.

Methods in Ecology and Evolution, Volume 16, Issue 10, Page 2170-2194, October 2025.Abstract Computational fluid dynamics (CFD) has become an essential tool for studying fluid interactions in biological systems. While widely used in engineering, its application in the natural sciences, particularly in paleobiology, remains limited due to the challenges of meshing complex organic geometries.

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 ...
