Competing species growing on a rugged front


Sherry Chu, Jordan Horowitz

Daniel Beller & David Nelson


Outline

I.      Range Expansion: Bacteria growing into new environment; models with and without a rough front

II.     Coalescence of paths governs diversity and close ancestry

III.   Extinction on a rough front is distinct  from directed percolation

IV.    Morphologies of growing fronts governed by relevant parameters

V.    Deterministic growth profiles from seeds on an undulating substrate

VI.  Summary
