Claudia Chávez

Claudia is an organic geochemist graduated from the University of Bristol, United Kingdom. She is based at the Institute of Geophysics (UNAM) in Mexico City and her research mainly focuses on reconstructing paleoenvironmental changes and climatic forces, based on geochemistry, lipid biomarkers, C isotopes from specific (molecular) compounds and ostracods paleoecology. She works with paleolake sediments, specially from dry areas such as the Chihuahua Desert in north of Mexico. However, she is also involved in other projects of North American Tropical region (Lake Chalco, Lake Texcoco, Neotropical karstic Lakes) reconstructing the paleoecology of ostracods during the last 147,000 years BP.

Survivors! Resilience and adaptations of freshwater ostracodes in ancient Lakes Petén Itzá (northern Guatemala) and Chalco (central Mexico) to climate and environmental changes over the last 80,000 years

  The North American Tropics hosts lakes of diverse origins and limnological characteristics, which are located along a broad altitudinal gradient, from 0 to 5675 masl. The region possesses several ancient lakes that have accumulated sediments continuously, in some cases for >400,000 years. Study of those lake deposits has enabled scientists to infer past climate and environmental conditio ...[Read More]
