Influence of Physiological Phenology on the Seasonal Pattern of Ecosystem Respiration in Deciduous Forests

Understanding the environmental and biotic drivers of respiration at the ecosystem level is a prerequisite to further improve scenarios of the global carbon cycle. In this study we investigated the relevance of physiological phenology, defined as …

Extreme Events in Gross Primary Production: A Characterization across Continents

Climate extremes can affect the functioning of terrestrial ecosystems, for instance via a reduction of the photosynthetic capacity or alterations of respiratory processes. Yet the dominant regional and seasonal effects of hydrometeorological extremes …

Semiempirical Modeling of Abiotic and Biotic Factors Controlling Ecosystem Respiration across Eddy Covariance Sites

In this study we examined ecosystem respiration (RECO) data from 104 sites belonging to FLUXNET, the global network of eddy covariance flux measurements. The goal was to identify the main factors involved in the variability of RECO: temporally and …

Global Convergence in the Temperature Sensitivity of Respiration at Ecosystem Level

The respiratory release of carbon dioxide (CO2) from the land surface is a major flux in the global carbon cycle, antipodal to photosynthetic CO2 uptake. Understanding the sensitivity of respiratory processes to temperature is central for quantifying …
