Spatial Representativeness of MexFlux as a Regional FLUXNET Network
Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 12, December 2025.Abstract Environmental observatory networks are fundamental in advancing scientific understanding of biogeochemical processes. FLUXNET is a global network of regional eddy covariance networks that measure ecosystem‐scale exchanges of greenhouse gases (e.g., CO2, CH4, H2O) and energy between the biosphere and the atmosphere.

Wildlife Biology, Volume 2025, Issue 5, September 2025.Water availability strongly influences the ecology of terrestrial birds and mammals. It will likely play an increasing role as a limiting factor as climate change and human demand make water availability scarcer. However, we lack a knowledge synthesis describing our current understanding of the use of water sources, particularly for wildlife hydration.
