Stable Isotope Tracers of Cretaceous Arctic Paleoprecipitation Open
We report estimated stable isotope compositions of depositional waters and paleoprecipitation from the Cretaceous Arctic to further elucidate the role of the global hydrologic cycle in sustaining polar warmth during that period. Estimates …

Synchronous Marine and Terrestrial Carbon Cycle Perturbation in the High Arctic During the PETM Open
The Paleocene‐Eocene Thermal Maximum (PETM; 56 Ma) is considered to be one of the best analogs for future climate change. The carbon isotope composition (δ 13 C) of n ‐alkanes derived from leaf waxes of terrestrial plants and marine algae …

Synchronous Marine and Terrestrial Carbon Cycle Perturbation in the High Arctic during the PETM Open
The samples collected were from Core BH9-05 from the Paleogene Central Basin, Spitsbergen (~77.83 ^o^N, 16.5 ^o^E). The expedition was the result of a Paleo-Arctic Climates and Environments Project (pACE) sponsored by the Worldwide Univers…

Population differences in host plant preference and the importance of yeast and plant substrate to volatile composition Open
Divergent selection between environments can result in changes to the behavior of an organism. In many insects, volatile compounds are a primary means by which host plants are recognized and shifts in plant availability can result in chang…
