In conjunction with the interdisciplinary activities of the National Institute for Mathematical and Biological Synthesis (NIMBioS), a seminar series will be hosted at NIMBioS every other Tuesday at 3:30 p.m. in the NIMBioS Lecture Hall on the 4th floor of 1534 White Ave., Suite 400 Seminar speakers will focus on their research initiatives at the interface of mathematics and many areas of the life sciences. Light refreshments will be served starting at 3 p.m.
Time/Date/Location: 3:30 p.m., Nov. 23, NIMBioS Lecture Hall, 1534 White Ave., Suite 400
Speaker: Dr. Robert Gilman, NIMBioS Postdoctoral Fellow
Topic: Hybridization, species collapse, and other strange stories
Abstract: There are now a number of well-studied cases in which pairs of incipient species have collapsed into hybrid swarms. It has been hypothesized that such collapses may occur when an environmental disturbance weakens the pre-mating barriers to reproduction between species. Gilman uses individual-based models to investigate the conditions under which this mechanism might lead to species collapse and to predict the long-term evolutionary outcomes of such collapse events. Gilman will also address the mechanisms that underlie the forward process of adaptive speciation and will briefly discuss speciation probabilities when disruptive selection occurs in one or more than one ecological dimension.
