| life form-specific gradients in compound-specific hydrogen isotope ratios of modern leaf waxes along a north american monsoonal transect. | the use of hydrogen isotope ratios (δ(2)h) of sedimentary n-alkanes from leaf waxes has become an important tool for reconstructing paleoenvironmental and ancient hydrologic conditions. studies of modern plant waxes can elucidate driving ecological mechanisms behind geologic deposits. here, we used a transect across the north american monsoon region of the western usa from tucson, arizona to salt lake city, utah to study variations in leaf wax δ(2)h among co-occurring plants. three co-occurring ... | 2015 | 26310435 |
