Silvia Pineda-Munoz is a paleoecologist who studies the effects of perturbations like urbanization, extirpations or climate change on ecosystems past and present.  She works to understand ecological and evolutionary processes at multiple temporal, geographical and taxonomic scales. The recent fossil record documents a long-term natural experiment on the effects of environmental and ecological change on ecosystems and taxa that were already around before the expansion of human civilizations. Thus, merging ecology and paleontology offers a unique perspective on conservation biology and provides an important tool for understanding the cascading effects of losing both taxonomic and functional biodiversity.
