The damage and injury that ground level ozone (O3) causes vegetation has become
increasingly evident over the past half century with a large body of observational and …

How plants interact with sunlight is central to the existence of life and provides a window to
the functioning of ecosystems. Although the basic properties of leaf spectra have been …

Carbon sink in terrestrial ecosystems is critical for achieving carbon neutrality; however, its
environmental sensitivity and potential remain uncertain. A comprehensive framework was …

Anthropogenic activities have increased nitrogen (N) deposition by threefold to fivefold over
the last century, which may considerably affect soil respiration (Rs). Although numerous …

The global carbon budget is, of course, balanced. The conservation of carbon and the first
law of thermodynamics are intact.“Balancing the carbon budget” refers to the state of the …

Human activities have greatly accelerated emissions of both carbon dioxide and biologically
reactive nitrogen to the atmosphere,. As nitrogen availability often limits forest productivity, it …

Plant respiration constitutes a massive carbon flux to the atmosphere, and a major control on
the evolution of the global carbon cycle. It therefore has the potential to modulate levels of …

Understanding what controls global leaf type variation in trees is crucial for comprehending
their role in terrestrial ecosystems, including carbon, water and nutrient dynamics. Yet our …

Atmospheric pollutants have both beneficial and detrimental effects on carbon uptake by
land ecosystems. Surface ozone (O 3) damages leaf photosynthesis by oxidizing plant cells …

Results from 16 free‐air CO2 enrichment (FACE) sites representing four different global
vegetation types indicate that only some early predictions of the effects of increasing CO2 …
