Liseth Pérez

Liseth is a Guatemalan micropaleontologist and (paleo) ecologist based in Germany that uses aquatic bioindicators in lake sediment sequences to investigate the effects of past climate and environmental changes on aquatic ecosystem biodiversity and health in the North American Tropics. Her research focuses on multiple paleobioindicators such as microcrustaceans (ostracodes, cladocerans), chironomids, testate amoebae, and diatoms, and interprets her findings in conjunction with data from other aquatic animal and plant bioindicator groups, and from non-biological sediment variables (e.g. elemental chemistry, stable isotopes, magnetic properties, particle size analysis, mineralogy). She is mainly interested on paleoclimate and paleolimnological records from ancient lakes. For instance, Liseth serves as Co-PI for several International Continental Scientific Drilling Program (ICDP) projects in Nicaragua (NICABRIDGE), Mexico (MEXIDRILL) and Guatemala (LIBRE), and she is also involved in two other ICDP projects (PISDP, Guatemala and JUNIN, Perú).

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

Liseth Pérez and Claudia Chávez September 28, 2023

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]
