Antibiotics, by definition, reduce bacterial growth rates in optimal culture conditions;
however, the real-world environments bacteria inhabit see rapid growth punctuated by …

Deterministic evolutionary theory robustly predicts that populations displaying altruistic
behaviors will be driven to extinction by mutant cheats that absorb common benefits but do …

We study individual-based dynamics in finite populations, subject to randomly switching
environmental conditions. These are inspired by models in which genes transition between …

The assumption of constant population size is central in population genetics. It led to a large
body of results that is robust to modeling choices and that has proven successful to …

Evolutionary transitions between male and female heterogamety are common in both
vertebrates and invertebrates. Theoretical studies of these transitions have found that, when …

It is well known that, during replication, RNA viruses spontaneously generate defective viral
genomes (DVGs). DVGs are unable to complete an infectious cycle autonomously and …

We develop a perturbation method for studying quasineutral competition in a broad class of
stochastic competition models and apply it to the analysis of fixation of competing strains in …

Abstract Systems composed of large numbers of interacting agents often admit an effective
coarse-grained description in terms of a multidimensional stochastic dynamical system …

Theoretical studies from diverse areas of population biology have shown that demographic
stochasticity can substantially impact evolutionary dynamics in finite populations, including …

The adaptive voter model is a paradigmatic model in the study of opinion formation. Here we
propose an extension for this model, in which conflicts are resolved by obtaining another …
