Stable isotopes in tree rings: towards a mechanistic understanding of isotope fractionation and mixing processes from the leaves to the wood
The mechanistic understanding of isotope fractionation processes is increasing but we still
lack detailed knowledge of the processes that determine the isotopic composition of the tree …

Sensitivity of plants to changing atmospheric CO2 concentration: from the geological past to the next century
The rate of CO 2 assimilation by plants is directly influenced by the concentration of CO 2 in
the atmosphere, ca. As an environmental variable, ca also has a unique global and historic …

The energetic and carbon economic origins of leaf thermoregulation
Leaf thermoregulation has been documented in a handful of studies, but the generality and
origins of this pattern are unclear. We suggest that leaf thermoregulation is widespread in …

New constraints on atmospheric CO2 concentration for the Phanerozoic
Earth's atmospheric CO2 concentration (ca) for the Phanerozoic Eon is estimated from
proxies and geochemical carbon cycle models. Most estimates come with large, sometimes …

Plant thermoregulation: energetics, trait–environment interactions, and carbon economics
Building a more predictive trait-based ecology requires mechanistic theory based on first
principles. We present a general theoretical approach to link traits and climate. We use plant …

Covariation between oxygen and hydrogen stable isotopes declines along the path from xylem water to wood cellulose across an aridity gradient
Oxygen and hydrogen isotopes of cellulose in plant biology are commonly used to infer
environmental conditions, often from time series measurements of tree rings. However, the …
