UA Science Café at Tumamoc Hill – 'The Multiple Forces of Natural Selection on Seed Size in a Desert Annual Plant'

Wednesday, March 14, 2018 - 6:00pm

The Science Café at Tumamoc Hill provides speakers on topics that relate to the science, history, archeology and the educational mission of Tumamoc Hill, located to the west of "A" Mountain, near downtown. The talks are held in the library of the old Desert Laboratory, the buildings that are roughly halfway up the hill. The staff asks that you make a reservation for the Science Café so sufficient shuttle service can be provided for participants. Please contact Cynthia Anson at the phone number or email address listed below to reserve a seat.

Talk: "The Multiple Forces of Natural Selection on Seed Size in a Desert Annual Plant"

Presenter: Eugenio Larios, Consortium for Arizona-Mexico Arid Environments postdoctoral fellow, Instituto de Ecologia, National Autonomous University of Mexico (UNAM)

Talk description: Our speaker will show how selection on seed size is influenced by three environmental forces in the wild: water availability, competition and predation by ants and rodents. Seed size is a key plant functional trait that has fitness consequences through the life cycle and therefore under selective pressure.
