TL;DR: The seasonal changes in molecular and isotopic compositions suggest that leaf wax n-alkanes in these subtropical deciduous tree species integrate environmental information over a large portion of the annual growth cycle in response to fluctuations in environmental stresses.

TL;DR: In this paper, a 14 C-dated sediment core was used to identify three main lithostratigraphic units of this core that reveal a succession of changes in sediment delivery and accumulation as postglacial sea level rose and Holocene climate on land evolved, indicating that climate driven changes had only secondary controls on delivery of detrital sediment components to the Cabo Frio shelf.

TL;DR: In this article, a shipboard analysis was carried out on the free biomarker fraction of total lipid extracts of 10 Cretaceous black shale samples from Sites 1257 and 1258.

TL;DR: In this article, a comparison of the total nitrogen and organic carbon isotopic compositions of sediment sequences from the Tyrrhenian and Levantine Basins that contain three same-age sapropels reveals evidence of both similarities and differences in mid-Pleistocene sapropel-forming conditions in the western and eastern Mediterranean Sea.

TL;DR: In Pyramid Lake, a salt lake in Nevada, a 30% reduction in volume over the past 100 yr due to diversion of river inflow for irrigation of farmland was reported as discussed by the authors.
