Biodiversity and Refugia - Lessons Learned from the Past

Convenors

Sheri Fritz, Surangi Punyasena, Kathy Willis

Description

The geological record provides insight into the long-term dynamics of populations and communities and the processes that generate biodiversity, including the role of cold and warm-stage refugia, where organisms persisted through unfavorable environmental conditions in adjoining areas.  

This session welcomes contributions that use fossils, molecular and geochemical tools, and/or modeling to examine how climate change, biological interactions, or other environmental conditions affected the past and present composition and distribution of organisms and influenced patterns of biodiversity. We invite contributions from high to low latitudes and that consider any time interval within the Cenozoic.
