Data from: Antagonistic coevolution between quantitative and Mendelian traits

Coevolution is relentlessly creating and maintaining biodiversity, and
therefore has been a central topic in evolutionary biology. Previous
theoretical studies have mostly considered coevolution between genetically
symmetric traits (i.e., coevolution between two continuous quantitative
traits or two discrete Mendelian traits). However, recent empirical
evidence indicates that coevolution can occur between genetically
asymmetric traits (e.g., between quantitative and Mendelian traits). We
examine consequences of antagonistic coevolution mediated by a
quantitative predator trait and a Mendelian prey trait, such that
predation is more intense with decreased phenotypic distance between their
traits (phenotype matching). This antagonistic coevolution produces a
complex pattern of bifurcations with bistability (initial state
dependence) in a two-dimensional model for trait coevolution. Further,
with eco-evolutionary dynamics (so that the trait evolution affects
predator-prey population dynamics), we find that coevolution can cause
rich dynamics including anti-phase cycles, in-phase cycles, chaotic
dynamics, and deterministic predator extinction. Predator extinction is
more likely to occur when the prey trait exhibits complete dominance
rather than semidominance and when the predator trait evolves very
rapidly. Our study illustrates how recognizing the genetic architectures
of interacting ecological traits can be essential for understanding the
population and evolutionary dynamics of coevolving species.
