Arbuscular mycorrhizal fungi form symbioses with ~70% of plant species, building hyphal networks that exchange nutrients for host-derived carbon. These tubular networks move ~1 billion metric tons of ...

Mapping Earth’s underground mycorrhizal fungal networks — the hidden infrastructure beneath our feet.

Structures called plastoglobules organize the enzymes that turn nitrogen into compounds needed for plant growth, offering lessons for sustainable agriculture.

The Cerrado, largely overlooked in climate science and policy, is a critical carbon sink, according to new research.

Caltech mineralogist George Rossman (PhD '71) passed away on February 6, 2026.

The carbon cycle community calls for an integrated carbon observing system leveraging near-surface partial-column data to better resolve finer spatial scales where key processes and decisions occur.

A study in Iceland found that microbes are hoarding more nitrogen for themselves, altering nutrient cycling and leaving less for plants.

The carbon cycle community calls for an integrated carbon observing system leveraging near-surface partial-column data to better resolve finer spatial scales where key processes and decisions occur.

Optimization approaches based on fundamental eco-evolutionary principles (EEO approaches) can increase the realism and generality of microbial-explicit soil organic matter (SOM) models—yet, these app....

The Trump administration is planning to dismantle the National Center for Atmospheric Research, one of the world’s leading climate and Earth science research laboratories, according to a statement fro...

The Trump Administration has vowed to dissolve the center that provides critical extreme weather and climate data for our nation.

From NASA to the National Institutes of Health, federal agencies conduct research that universities cannot. Agency scientists speak out about the irreplaceable facilities, institutional knowledge and training opportunities that the country is losing.

Rising CO2 and climate change are redistributing terrestrial carbon fluxes and reservoirs across latitudes and reducing carbon residence times globally.

CO2 ${\text{CO}}_{2}$-driven terrestrial C gains are ∼4 times greater than climate-driven losses during 2001–2021 and are mainly in live biomass reservoirs In the global sum, CO2 ${\text{CO}}_{2}...

The rapid increase in the volume and variety of terrestrial biosphere observations offers a unique opportunity to derive ecological insights, refine process-based models, and improve forecasting for ...

By Renato Braghiere Vegetation plays a critical role in regulating Earth’s climate by absorbing sunlight, exchanging moisture with the atmosphere, and sequestering carbon. Yet, how vegetation is re…

Additional sink inferred by inversions in just 16% of North America accounts for the discrepancy between top-down and bottom-up estimates Statistically significant differences between top-down an...

In the ever-evolving quest to understand Earth's complex climate system, researchers have continually sought to improve the precision of Earth system models (ESMs) by integrating more detailed

Earth system models often categorize plants to just a few functional types, and plant characteristics are defined per type, neglecting their diversity. The authors show how the use of plant traits can...

Natural selection favors growth by selecting a combination of plant traits that maximize photosynthetic CO2 assimilation at the lowest combined carbon costs of resource acquisition and use. We quant...
