Óscar Pérez-Priego

Prof. Óscar Pérez-Priego is an ecophysiologist at the University of Córdoba, Spain. He received his PhD in Biogeosciences at the University of Córdoba (2011), investigating plant water relations in Mediterranean drylands. After his doctorate, he completed postdoctoral appointments at the University of Granada (2011-2014), the Max Planck Institute for Biogeochemistry in Jena (2014-2019) and at Macquarie University in Sydney (2019-2021), where he advanced research on ecohydrological stress processes and ecosystem–atmosphere exchanges across contrasting climates and management conditions. His research focuses on multi-scale ecohydrological integration — from stem water potential, eddy covariance fluxes up to remote sensing scales — to unravel the physiological mechanisms driving drought impacts.

Is How We View the Atmosphere Too Dry?

Is How We View the Atmosphere Too Dry?

Many people think about air as a fixed mix of gases like nitrogen, oxygen, and carbon dioxide (CO2). But the main reason the composition of air changes—water vapour—tends to get overlooked. Scientists often remove it from atmospheric samples before analysing air composition, and this convenient habit can make us forget something surprising: water vapour isn’t just “in” the air; it is air, and when ...[Read More]
