Evolutionary Dynamics Within and Among Competing Groups

no code implementations5 Sep 2022 Daniel B. Cooney, Simon A. Levin, Yoichiro Mori, Joshua B. Plotkin

We apply this theory to analyze how mechanisms known to promote cooperation within a single group -- including assortment, reciprocity, and population structure -- alter evolutionary outcomes in the presence of competition among groups.

Sharp thresholds limit the benefit of defector avoidance in cooperation on networks

no code implementations21 Oct 2021 Ashkaan K. Fahimipour, Fanqi Zeng, Martin Homer, Arne Traulsen, Simon A. Levin, Thilo Gross

Consider a cooperation game on a spatial network of habitat patches, where players can relocate between patches if they judge the local conditions to be unfavorable.

A PDE Model for Protocell Evolution and the Origin of Chromosomes via Multilevel Selection

no code implementations20 Sep 2021 Daniel B. Cooney, Fernando W. Rossine, Dylan H. Morris, Simon A. Levin

We find that the gene-level advantage of fast replicators casts a long shadow on the multilevel dynamics of protocell evolution: no level of between-protocell competition can produce coexistence of the fast and slow replicators when the two genes are equally needed for protocell-level reproduction.

Optimal, near-optimal, and robust epidemic control

1 code implementation5 Apr 2020 Dylan H. Morris, Fernando W. Rossine, Joshua B. Plotkin, Simon A. Levin

Here we derive the theoretically optimal strategy for using a time-limited intervention to reduce the peak prevalence of a novel disease in the classic Susceptible-Infectious-Recovered epidemic model.

Probabilistic Foundations of Spatial Mean-field Models in Ecology and Applications

2 code implementations15 Nov 2019 Denis D. Patterson, Simon A. Levin, A. Carla Staver, Jonathan D. Touboul

Deterministic models of vegetation often summarize, at a macroscopic scale, a multitude of intrinsically random events occurring at a microscopic scale.
