Bridging the Energy Balance Gap in Eddy‐Covariance Measurements: Insights From Standardized Network Data

Global Change Biology, Volume 32, Issue 5, May 2026.
Written Summary: Measuring energy exchanges between land and atmosphere is fundamental to understanding climate, but these measurements are systematically incomplete, with 20%–40% of energy consistently unaccounted for. Analyzing data from 84 sites worldwide, we show that carefully tracking all energy components and applying strict data quality filters

La criticalité auto-organisée des feux de forêts marocaines

Revue Marocaine des Sciences Agronomiques et Vétérinaires, 2013
La Criticalité Auto-Organisée (CAO) des feux de forêts marocaines est étudiée à partir d’une analyse d’une série de données historiques (1960 à 2011). En effet, cette analyse montre que les relations entre les surfaces brûlées annuelles normalisées par ...

Phylogenetic constraints, conservatism, and convergence shape three‐dimensional variation in flower morphology of a tropical orchid radiation

The Plant Journal, Volume 126, Issue 3, May 2026.
SUMMARY Despite advances in phylogenetic comparative methods, challenges remain to distinguish between various macroevolutionary patterns of phenotypic variation (e.g., conservatism, convergence) and to infer their underlying proximate (genetic, developmental) or ultimate (selective versus neutral) causes.

The Hematite Question: Hydrogen‐Driven Magnetization of Hematite‐Bearing Sandstones and Insights for Natural Hydrogen Exploration

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Natural hydrogen is a promising clean energy resource, but locating subsurface accumulations remains challenging. Aeromagnetic anomalies are increasingly utilized as a rapid and cost‐effective tool for geological hydrogen prospection, particularly associated with magnetite formation during abiotic geochemical hydrogen generation through ...

First Time-dependent Study of H2 and H3+ Ortho-Para Chemistry in the Diffuse Interstellar Medium: Observations Meet Theoretical Predictions

, 2014
The chemistry in the diffuse interstellar medium initiates the gradual increase of molecular complexity during the life cycle of matter. A key molecule that enables build-up of new molecular bonds and new molecules via proton-donation is H3+.
