The Reconstruction of Climate in Beringia by analysis of Glycerol Dialkyl Glycerol Tetraether (GDGT) Distributions using High Performance Liquid Chromatography – Mass Spectrometry (HPLC-MS).
… derived in other works were used to reconstruct paleoclimates herein. Thirty polar sediment extracts were analysed by high-performance liquid chromatography coupled via atmospheric pressure chemical ionisation to mass spectrometric detection (HPLC-APCI-MS). Glycerol dialkyl glycerol tetraether …

Depositional Environments and Sequence Stratigraphy of Upper Mississippian Strata in the Central Appalachian Basin
The Upper Mississippian Hinton, Princeton, and Bluestone formations of southern West Virginia constitute a wedge of strata that filled the Appalachian basin over a ~7 million year time interval. Seventeen transgressive-regressive sequences comprise the study interval in the basin depocenter. Five …

Reconstructing Past Population Dynamics and Movements from Genomic and Environmental Data
… combines genetics, ecological niche models and paleoclimates, to reconstruct the demography of tigers. I found that, similar to African leopards, the structure of extant tigers is weak due to strong connectivity caused by stable climate conditions. Importantly, I show that the extinct Caspian …
