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, October 30, 2012, 3:30 p.m.*
Location: Room 206, Claxton Building, 1122 Volunteer Blvd.
Speaker: Dr. Julia Earl, NIMBioS Postdoctoral Fellow
Topic: Animal behavior and ecosystems: Linking movement ecology to spatial subsidies
Abstract: Cross-ecosystem transfer of energy and nutrients (spatial subsidies) can greatly impact recipient ecosystems. These impacts can be positive, including ecosystem services, and negative, such as the transport of contaminants. Many subsidies are actively moved by animals, which regularly transfer nutrients within and among ecosystems. The movement ecology of these animals determines where and when active subsidies are deposited. In this talk, I will examine how different animal movement strategies (correlated random walks) and patterns of mortality risks (uniform, edge and gradient risks) alter the spatial extent and density of nutrient/energy subsidies (dead animals) and consumer subsidies (alive animals). These types of predictions will help us to identify scenarios where active subsidies are likely to have large impacts on recipient systems and subsequently function as important ecosystem services or contaminant vectors.
*Join us for refreshments at 3 p.m. in the 1st floor visitor breakroom.
