The paper shows that spatial structure in host populations drives the evolution of parasites into host defense systems through the emergence of hyperparasites.

The paper shows that sublethal immune resistance can mimic tolerance in reaction-norm analysis, challenging the distinction between resistance and tolerance.

The paper uses mathematical models to compare guarding and self-guarding mechanisms in innate immunity, finding self-guarding leads to faster immune responses but higher false positives.

This study investigates how coevolutionary cycling in allele frequencies affects virulence evolution in a free-living parasite using population and quantitative genetic approaches.

This study models how age-specific tolerance and virulence coevolve and finds that age structure influences coevolutionary dynamics and virulence selection.

The paper introduces a method to determine convergence stability in coevolutionary processes where one species evolves much faster than the other, reducing computational complexity by separating timescales.
