| Title: | Non-local properties in the evolution of spatially-structured populations |
| Seminar: | Seminar on Probability and its Application |
| Speaker: | Timothy Reluga, PSU |
| Abstract: |
| Under the simplest conditions, evolutionary
theory predicts that natural selections drives pathogens
toward equilibrium values of their discounted reproduction
ratios, $\mathcal{R}_d$. In the absences of biological
constraints, these equilibria correspond to maximization of
the transmission rate and minimization of their removal
rate. However, many authors have observed that correlations
in the biological relationship between transmission and
removal can lead to equilibria with intermediate values of
these parameters.
These results are typically derived under strong-mixing
assumptions. Surprising computational work on
cellular-automata models has further indicated that even in the
absence of biological correlations, spatial structure in
disease transmission patterns can be sufficient to alter
pathogen evolution. In this talk, I'll describe some of my
lab's recent and ongoing research into this question that was
undertaken by a visiting undergraduate student last summer. |
