Evo + | Birth-death process. Which individual reproduces depends on the current fitness effect by the antagonist, normalised by the population average fitness effects (+) | intraspecific competition (+) | slow extinction | stasis | NFDS | no |
Evo | Like Evo + but fitness effects are compared between two individuals not with the population average | pairwise competition | slow extinction | NFDS | extinction | no |
Hybrid | Hybrid model with reactions between two genotypes of different populations, single birth of parasite and death of host by dynamically adjusted rates. | no competition | extinction | NFDS | extinction | yes, but dynamically constrained |

EcoEvo + | Independent reactions between individual hosts and parasites, single birth and death events or competition in hosts | intra-host competition (+) | fast extinction | stasis | NFDS | yes, but carrying capacity |
EcoEvo | Like EcoEvo + but without competition within hosts. For infinite population size this is the Lotka-Volterra dynamics | no competition | fast extinction | NFDS | extinction | yes, uncon-strained |
