Dynamics of the latitudinal diversity gradient: Integrating fossil and present‐day data

November 5th at 12:45 p.m.

Eckart 227

Integration of paleobiologic and biogeographic data in marine bivalves shows that two supposedly opposing models for the shaping of the latitudinal diversity gradient, as shaped primarily either by latitudinal trends in local environmental factors or by the spatial dynamics of lineages, actually operate simultaneously. The different currencies of biodiversity – taxonomic, functional, and morphological – show distinct behaviors along the gradient, arguing for a multi-level approach to the most pervasive biotic patterns on Earth.

 

Bio:

David Jablonski is the William R. Kenan Jr. Distinguished Service Professor in the Department of Geophysical Sciences at the University of Chicago. He combines data on living and fossil marine organisms to ask large-scale evolutionary questions about origins, extinctions, and spatial dynamics of life on Earth. He is an elected member of the American Academy of Arts and Sciences and the National Academy of Sciences, a recipient of the Medal of the Paleontological Society, and has published more than 170 scientific papers and book chapters on topics ranging from mass extinctions to the role of multilevel processes in evolution.
