Spatial competition and the dynamics of rarity in a temporally varying environment
Lauren O'Malley, G. Korniss, Sai Satya Praveen Mungara +1
Given an endogenous timescale set by invasion in a constant environment, we introduced periodic temporal variation in competitive superiority by alternating the species' propagatio…
Ecological Invasion, Roughened Fronts, and a Competitor's Extreme Advance: Integrating Stochastic Spatial-Growth Models
Lauren O'Malley, G. Korniss, Thomas Caraco
Both community ecology and conservation biology seek further understanding of factors governing the advance of an invasive species. We model biological invasion as an individual-ba…
Fisher Waves and Front Roughening in a Two-Species Invasion Model with Preemptive Competition
L. O'Malley, B. Kozma, G. Korniss +2
We study front propagation when an invading species competes with a resident; we assume nearest-neighbor preemptive competition for resources in an individual-based, two-dimensiona…
Fisher Waves and the Velocity of Front Propagation in a Two-Species Invasion Model with Preemptive Competition
L. O'Malley, B. Kozma, G. Korniss +2
We consider an individual-based two-dimensional spatial model with nearest-neighbor preemptive competition to study front propagation between an invader and a resident species. In…
Invasive advance of an advantageous mutation: nucleation theory
Lauren O'Malley, James Basham, Joseph A. Yasi +3
For most organisms with viscous population structure, spatially localized growth drives the invasive advance of a favorable mutation. We model a two-allele competition where recurr…
