  • My first single-author publication. I developed a mathematical model to predict how the dispersal bias among infected individuals and uninfected individuals can emerge as a result of selection on the whole dispersal process. This model would play a general key role when we are to measure dispersal bias when dispersal is conditional. There is a Key in Appendix: I applied a theorem of Karush-Kuhn-Tucker in convex analysis to prove the boundary singular strategy is evolutionarily stable strategy. This work is supported by JSPS.

[1] R. Iritani* & Y. Iwasa (2014) Parasite infection drives the evolution of state-dependent dispersal of the host.
Theoretical Population Biology.

  • This is my first publication, that I was engaged in during master course. We used a neighbor-modulated approach and adaptive dynamics to investigate how the host dispersal might evolve under parasitism. The key parameters are recovery, selection against infected emigrants, and virulence. Surprisingly, high virulence favors high dispersal tendency in infected individuals. Below I show some of the comments that I received from reviewers. I really appreciate their sincere comments.

    This manuscript is generally sound, gets around most of the biological details that help put it in proper context, and is quite well-written. I have some suggestions as to how to improve the manuscript, but the authors should consider them as improvements to an already good paper.

    I fully support the publication of this work, but have some significant suggestions as to how the presentation could be improved
