Individual variation in susceptibility and exposure is subject to selection by natural infection,
accelerating the acquisition of immunity, and reducing herd immunity thresholds and …

As severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spreads, the susceptible
subpopulation declines causing the rate at which new infections occur to slow down …

Intraspecific trait variation (ITV) is a widespread feature of life, but it is an open question how
ITV affects between‐species coexistence. Recent theoretical studies have produced …

Individual vital rates, such as mortality and birth rates, are key determinants of lifetime
reproductive success, and variability in these rates shapes population dynamics. Previous …

Mathematical models are increasingly adopted for setting disease prevention and control
targets. As model-informed policies are implemented, however, the inaccuracies of some …

Selection acting on unobserved heterogeneity is a fundamental issue in the mathematics of
populations. As recognised in disciplines as diverse as demography [,,], ecology [,] …

One of the most fundamental issues in evolutionary biology is how unicellular life
transitioned to multicellular life. How—and why—was it that the simplest single-celled …
