Signatures and forgeries: optimality in a coevolutionary arms race
When species interact antagonistically, ‘arms races’ played out on coevolutionary battlegrounds can drive the rapid evolution of intricate and complex adaptations in each species. However, evolution in one species may prevent optimality in these adaptations from being realised in the other. In the …

Coevolution Between Grasshopper mice (Onychomys spp.) and Bark and Striped Scorpions (Centruroides spp.)
… strongest argument for rejecting hypotheses of coevolutionary arms races between predators and prey. In many cases there is evidence of increased investment by the prey in response to the predator, but no evidence of increased investment by the predator in response to the prey, thus producing …

Host-parasite co-evolution and genetic variation at the major histocompatibility complex in the Trinidadian guppy (poecilia reticulata)
… in MHC allele frequencies as evidence for a coevolutionary arms race between host immune genes and parasite virulence genes (i.e. Red Queen dynamics). In this theoretical chapter, I explore whether such data can also be explained by simple overdominant selection in combination with migration …

Phenotypic consequences of adaptive toxin production and resistance in coevolutionary partners
… arise, and they may limit the extent to which coevolutionary arms-race dynamics between predator and prey develop, determining which party will best the other. In the western U.S., toxic Pacific newts (Taricha) are defended by a highly potent neurotoxin. This neurotoxin makes them too dangerous …
