NIMBioS Seminar Series

In conjunction with the interdisciplinary activities of the National Institute for Mathematical and Biological Synthesis (NIMBioS), a seminar series on topics in mathematical biology will be hosted at NIMBioS every other Tuesday at 3:30 p.m. (unless otherwise noted) in the Hallam Auditorium, Room 206, Claxton Building, 1122 Volunteer Blvd. 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 in the 1st floor visitor breakroom beginning 30 minutes before each talk. Faculty and students from across the UT community are welcome to join us.

Time/Date: Tuesday, February 26, 2013, 3:30 p.m.*
Location: Room 206, Claxton Building, 1122 Volunteer Blvd.
Speaker: Dr. Ludek Berec, Dept. of Theoretical Ecology, Institute of Entomology, Biology Centre, Academy of Sciences of the Czech Republic; a NIMBioS Postdoctoral Fellows Invited Distinguished Visitor
Topic: Allee effects and pest control
Abstract: Allee effects, or positive density dependence in one or more fitness components, still enjoy the glare of popularity, but are sometimes regarded as a sort of theoretical amusement with little practical consequences. This talk will deal with how Allee effects can be exploited in pest control. After briefly reviewing what Allee effects are and what supportive evidence we have for them, I will first illustrate how Allee effects can be strengthened to enhance pest control efficiency. One way of strengthening Allee effects is to introduce another component Allee effect, and I will present various ways in which component Allee effects may interact. Then I will demonstrate how Allee effects can be used to enhance efficiency of management of the invasive gypsy moth Lymantria dispar. Finally, I will show that neglecting uncertainty behind Allee effect estimation may generate false predictions of population extinction risk.

*Join us for refreshments at 3 p.m. in the 1st floor visitor breakroom.
