April: Understanding species range shifts through genetics, fossils, and models

On April 14th this year's theme of Science will continue with a talk by Yi-Hsin Erica Tsai, a postdoctoral researcher at Notre Dame.

Abstract:  As climates shift the habitable ranges for species often also shift.  In order to survive the habitat changing around them, species must move to newly habitable areas before old regions become inhospitable.  In my research, I look to the past and study how plants have coped with previous episodes of global warming as an allegory for the future.  For instance, what factors have limited the spread of parasites compared with their hosts?  What evidence do we have that chronicles the migration history of the trees in this area? Can we use DNA from fossils to understand past population changes? This talk will explore the analysis of genetic data, fossils, and models in understanding species range changes after the last ice age.

    It was very interesting. Although over my head scientifically, I really enjoyed it.

    That was a really good presentation! It was also fun to visit with everyone over at Eden afterward.

    I noticed after signing up the 4-28 coffee which is more accessible. So I might skip the 4/14 event for the 4/28 event. Won't know until 4/14 afternoon.

We just grab a coffee and speak French. Some people have been coming every week for months... it creates a kind of warmth to the group.

Rafaël, started French Conversation Group
