Beautiful California Diversity: The Biodiversity Crisis and what We Can Do About It. 

With Lynne Trulio

This speaker is funded by our

Louisa Beck Guest Lectures

We share the Earth with millions of other species. But our planet is experiencing a biodiversity crisis in which a significant portion of these species are in danger of extinction

in the coming decades.

In this talk, we will discuss the causes of the current biodiversity crisis, with a focus on California biodiversity. We will discuss which species are most endangered, what we can

do to try to limit the loss of species, and efforts in our region to preserve our local biodiversity, especially endangered plants, invertebrates and animal species.

Dr. Trulio has been a professor of Environmental Studies at San Jose State University since 1991, the department chair for the past 15 years and the Associate Dean of the College of Social Sciences for the

past 2 years. Dr. Trulio was the Lead Scientist for the South Bay Salt Pond Restoration Project from 2003- 2008 and 2016-2018, directing the Project's science program.

She received her Ph.D. in Ecology from

the University of California, Davis, and her undergraduate degree in Biology from Goucher College in Towson, MD.
