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

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 Permian–Triassic Boundary event at 252.2 Ma marks the largest extinction of marine
fauna in the Phanerozoic and there is a wide consensus that the extinction coincided with an …

Molecular fossils (biomarkers) are abundant in organic rich natural archives such as peats
and lignites (fossilized peat), where their distribution is governed by their biological source …

The rise of atmospheric oxygen has driven environmental change and biological evolution
throughout much of Earth's history and was enabled by the evolution of oxygenic …

A comprehensive organic geochemical investigation of the Hawsker Bottoms outcrop
section in Yorkshire, England has provided new insights about environmental conditions …

Cyanobacteria are ubiquitous, ecologically important and phylogenetically diverse
components of the phytoplankton of marine and freshwater environments, as well as some …

To reconstruct past environmental changes, a range of indirect or proxy approaches can be
applied to Quaternary archives. Here, we review the complementary and novel insights that …
