1 Molecular evolutionary signatures reveal the role of host ecological dynamics in viral disease emergence and spread by Scott M. Duke-Sylvester, Roman Biek, and Leslie A. Real Philosophical Transactions B Volume 368(1614):20120194 March 19, 2013 ©2013 by The Royal Society

2 (a) Skyline plots of the effective number of infections for six rates of LDT (red, ϕ LDT = 0; yellow, ϕ LDT = 3.73 × 10−8; green, ϕ LDT = 7.5 × 10−8; cyan, ϕ LDT = 1.5 × 10−7; blue, ϕ LDT = 3 × 10−7; violet, ϕ LDT = 6 × 10−7).

3 Linear relationship between the exponential growth rate estimated from the viral phylogeny (λskyline) and the rate estimated from the demographic record of the epidemic (λdemographic). Scott M. Duke-Sylvester et al. Phil. Trans. R. Soc. B 2013;368:20120194 ©2013 by The Royal Society

4 Growth in the effective number of infections (Neτ) during the three phases of the mid-Atlantic raccoon rabies epidemic [34]. Scott M. Duke-Sylvester et al. Phil. Trans. R. Soc. B 2013;368:20120194 ©2013 by The Royal Society

5 Indicators of spatial structure created by different rates of LDT. (a) Change in the strength of IBD at different rates of LDT. When there is long-distance dispersal between locations ( ϕ LDT ≠ 0) the slope (red) and correlation coefficient (blue) both decrea... Scott M. Duke-Sylvester et al. Phil. Trans. R. Soc.
