Climate constrains the enhancement of CO 2 fertilization on forest gross primary productivity
Forest gross primary production (GPP) is influenced by the interplay between climate conditions and atmospheric CO 2 levels, which interact in complex ways, generating both compensating and amplifying effects. In this study, eddy covariance flux measurements from 50 forest ecosystems were integrated with simulations from 14 terrestrial biosphere models to investigate how climate conditions and atmospheric CO 2 concentrations regulate forest GPP. …
Characterizing and communicating uncertainty: Lessons from Nasa’s Carbon Monitoring System
Navigating uncertainty is a critical challenge in all fields of science, especially when translating knowledge into real-world policies or management decisions. However, the wide variance in concepts and definitions of uncertainty across scientific fields hinders effective communication. As a microcosm of diverse fields within Earth Science, NASA’s Carbon Monitoring System (CMS) provides a useful crucible in which to identify cross-cutting concep…
Estimating forest extent across Mexico
Information on forest extent and tree cover is required to evaluate the status of natural resources, conservation practices, and environmental policies. The challenge is that different forest definitions, remote sensing-based (RSB) products, and data availability can lead to discrepancies in reporting total forest area. Consequently, errors in forest extent can be propagated into forest biomass and carbon estimates. Here, we present a simple appr…
Detecting vulnerability of humid tropical forests to multiple stressors
Spatial heterogeneity in CO 2 , CH 4 , and energy fluxes: Insights from airborne eddy covariance measurements over the Mid-Atlantic region
The exchange of carbon between the Earth’s atmosphere and biosphere influences the atmospheric abundances of carbon dioxide (CO 2 ) and methane (CH 4 ). Airborne eddy covariance (EC) can quantify surface-atmosphere exchange from landscape-to-regional scales, offering a unique perspective on carbon cycle dynamics. We use extensive airborne measurements to quantify fluxes of sensible heat, latent heat, CO 2 , and CH 4 across multiple ecosystems in …
Greenness trends and carbon stocks of mangroves across Mexico
Mangroves cover less than 0.1% of Earth’s surface, store large amounts of carbon per unit area, but are threatened by global environmental change. The capacity of mangroves productivity could be characterized by their canopy greenness, but this property has not been systematically tested across gradients of mangrove forests and national scales. Here, we analyzed time series of Normalized Difference Vegetation Index (NDVI), mean air temperature an…
SoilGrids250m: Global gridded soil information based on machine learning
This paper describes the technical development and accuracy assessment of the most recent and improved version of the SoilGrids system at 250m resolution (June 2016 update). SoilGrids provides global predictions for standard numeric soil properties (organic carbon, bulk density, Cation Exchange Capacity (CEC), pH, soil texture fractions and coarse fragments) at seven standard depths (0, 5, 15, 30, 60, 100 and 200 cm), in addition to predictions o…
How a hurricane disturbance influences extreme CO 2 fluxes and variance in a tropical forest
A current challenge is to understand what are the legacies left by disturbances on ecosystems for predicting response patterns and trajectories. This work focuses on the ecological implications of a major hurricane and analyzes its influence on forest gross primary productivity (GPP; derived from the moderate-resolution imaging spectroradiometer, MODIS) and soil CO _2 efflux. Following the hurricane, there was a reduction of nearly 0.5 kgC m ^−2 …

Fijación de nitrógeno por Cyanoprokaryota en la Reserva Ecológica El Edén, Q.R., México
Acetylene reduction assay (ARA) was applied to determine the rate of nitrogen fixation by cyanoprokaryotes in a wetland in El Edén Ecological Reserve. The data obtained throughout a hydrological cycle showed both an increase of fixed nitrogen during wet periods and an important amount of nitrogen rate produced by non-heterocytic filamentous and colonial blue-green algae. The results support the importance of the contribution of algae to nutrient …
