NASC Colloquium: "Biological invasions, mathematical models, and the effects of landscape heterogeneity on both"
Prof. Frithjof Lutscher, Dept of Mathematics & Statistics and Biology, University of Ottawa, will present a short overview on reaction-diffusion
models for biological invasions in homogeneous landscapes and then
present some new ideas on how to adapt these models for heterogeneous
landscapes. Biological invasions occur around the world and - thanks to
human transportation - at an increasing rate. Some of these invasions
have massive negative impacts on existing ecosystems and incur high cost
to our economies. He will present some results on the speed at which a
population spreads in these models and illustrate the results using
data from the emerald ash borer, a relatively recent forest insect pest
in north America. It turns out that landscape heterogeneity can
substantially increase the spread rate of an invader. Reception to follow. Co-sponsored by CORE Scientific Perspectives.
