An ASA Zoom Webinar*

Have you ever been stopped in your tracks in the Sonoran Desert by the sight of a single file line of ants crossing the path, each carrying a flower petal or large piece of a leaf?  Have you observed phainopepla birds frequenting mistletoe in desert trees, or seen white cottony masses on prickly pear pads and wondered if the cactus was dying?  Our speaker, Dr. Judith Bronstein, has devoted her professional career to studying interspecies interactions that lead to such curiosities.

Biologists have always been fascinated by strife and conflict; indeed, these concepts lie at the heart of theories of our understanding of ecology and behavior.  However, cooperative exchanges, involving all species and networking large numbers of them into complex communities, are ubiquitous in the natural world.  Which species cooperate?  Why do they cooperate?  How does cooperation evolve?  How can it persist if organisms are primarily looking out for themselves?  And what is the fate of mutualism in a rapidly changing world?  Dr Bronstein will provide examples of mutualisms that are important in southern Arizona

Judith Bronstein received her AB from Brown University, and MSc and PhD in Ecology and Evolutionary Biology from the University of Michigan.  Following postdoctoral fellowships at Le Centre National de la Recherche Scientifique in Montpellier, France, and at the University of Alberta, she joined the faculty of UA, and advanced to become Distinguished Professor of Ecology and Evolutionary Biology.  She has served as a member of numerous journal editorial boards, as Editor-in-Chief of The American Naturalist, and as Program Director in the Division of Environmental Biology for the National Science Foundation.
