These mating swarms have a male-biased operational sex ratio, which is expected to generate intense competition among males for mating opportunities.

Catching a wave: On the suitability of traveling-wave solutions in epidemiological modeling.

Ordinary differential equation models such as the classical SIR model are widely used in epidemiology to study and predict infectious disease dynamics. However, these models typically assume that populations are homogeneously mixed, ignoring possible variations in disease prevalence due to spatial heterogeneity. To address this issue, reaction-diffusion models have been proposed as an alternative approach to modeling spatially continuous populations in which individuals move in a diffusive manner.
