Screenshot of the following text: Lipid biomarkers: novel applications, calibrations and tools for environmental studies Lipid biomarkers are valuable tools for reconstructing a variety of environmental processes in modern and (geological) past settings. We seek studies that develop new lipid biomarkers and methods for applying biomarkers to modern settings and the geologic past to reconstruct environmental parameters such as temperature, precipitation, biogeochemical cycles, anthropogenic activities, and vegetation. These can be studies on the biosynthesis and phylogeny of source organisms, transport and diagenesis, calibrations to environmental parameters, proxy interpretation and applications to reconstruct past environmental conditions.

New paleoclimate seasonality paper! We find strong Mid-Holocene seasonality using δD from plants and algae to distinguish annual vs monsoon precipitation, multiproxy biomarkers and a climate model simulation. In QSR: www.sciencedirect.com/science/arti...
