NIMBioS Interdisciplinary Seminar
3:30 pm*, Tuesday, Nov. 23, Room 403, Blount Hall, 1534 White Ave.
"Hybridization, species collapse, and other strange stories"
Dr. Robert T. Gilman, NIMBioS Postdoctoral Research Fellow
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.
*Refreshments begin at 3 p.m. in the NIMBioS lobby on the 4th floor of
Blount Hall.
*Other seminar speakers this semester include the following:
Nov. 30: Philip Crowley, Dept. of Biology, Univ. of Kentucky
