Hydrogen-isotopic abundances of lipid biomarkers are emerging as important proxies in the
study of ancient environments and ecosystems. A decade ago, pioneering studies made use …

Leaf water contains naturally occurring stable isotopes of oxygen and hydrogen in
abundances that vary spatially and temporally. When sufficiently understood, these can be …

Reconstructing the Paleogene topography and climate of central Tibet informs
understanding of collisional tectonic mechanisms and their links to climate and biodiversity …

During the “Green Sahara” period (11,000 to 5000 years before the present), the Sahara
desert received high amounts of rainfall, supporting diverse vegetation, permanent lakes …

Molecular organic geochemical proxies are increasingly being utilized to reconstruct past
environmental conditions as new tools continue to be discovered and developed. To date …

Isotope ratios of actively cycled elements vary as a function of the biogeochemical
processes in which they participate and the conditions under which those processes occur …

We summarize the applications of molecular proxies in paleoclimatology. Marine molecular
records especially are proving to be of value but certain environmentally persistent …

The response of the terrestrial biosphere to warming remains one of the most poorly
understood and quantified aspects of the climate system. One way to test the behavior of the …

The extent to which leaf water D-enrichment (transpiration) and soil water D-enrichment
(evaporation) affect the D/H ratio of plant leaf waxes remains a contentious issue, with …

Leaf wax n-alkanes of terrestrial plants are long-chain hydrocarbons that can persist in
sedimentary records over geologic timescales. Since meteoric water is the primary source of …
