| 요약 | The eastern sector of Mexico's Trans-Mexican Volcanic Belt is a semi-arid region, where interannual rainfall variability is significantly stresses regional water resources and the livelihood of millions. The region is linked to a broader summert |
| 요약 | My first dissertation chapter uses instrumental data to diagnose the causes of El Nino-induced droughts in Mexico. This work explores the mechanisms responsible for rainfall changes over Central Mexico during the developing versus decaying phase |
| 요약 | My second dissertation chapter uses the oxygen stable isotope ratios (delta18O) of lacustrine carbonates as well as elemental geochemistry to reconstruct late Holocene drought in Central Mexico. This sub-centennially resolved record is the first |
| 요약 | My third dissertation chapter explores impacts of late Holocene droughts on the terrestrial ecosystems in Central Mexico. I reconstructed past vegetation and fire dynamics from pollen and microscopic charcoal, and compared these data to our stab |
| 요약 | My fourth chapter is an exploration of the causes of centennial-scale across Mexico and Central America in the late Holocene. This work identifies the spatiotemporal patterns of late Holocene drought by synthesizing Mesoamerican proxy records. I |
| 요약 | Finally, I synthesize the knowledge in each of the dissertation chapters and point to avenues of future research. |
