Global Consequences of Land Use

Land use has generally been considered a local environmental issue, but it is becoming a force of global importance. Worldwide changes to forests, farmlands, waterways, and air ...

A biochemical model of photosynthetic CO2 assimilation in leaves of C3 species

CRISPR-Cas Systems in Bacteria and Archaea: Versatile Small RNAs for Adaptive Defense and Regulation

Bacteria and archaea have evolved defense and regulatory mechanisms to cope with various environmental stressors, including virus attack. This arsenal has been expanded by the r...

Quantum Yields for CO₂ Uptake in C₃ and C₄ Plants

The quantum yields of C(3) and C(4) plants from a number of genera and families as well as from ecologically diverse habitats were measured in normal air of 21% O(2) and in 2% O...
