Abstract

Tropospheric ozone (O₃) and carbon dioxide (CO₂) are significant drivers of plant growth and chemical composition. We hypothesized that exposure to elevated concentrations of O₃ and CO₂, singly and in combination, would modify the chemical composition of Trifolium and thus alter its digestibility and nutritive quality for ruminant herbivores.
