While overhead came, arching green,
Many a shrub and parasite,
To crown their Queen;

In science:

The interactions between hosts and parasites are very complex.
Biological Evolution and Statistical Physics
If the parasite draws too heavily on the host’s resources, the host may die quickly, and with it the survival chance of the parasite.
Biological Evolution and Statistical Physics
This argument has lead to the expectation that parasites should evolve to a moderate level of virulence.
Biological Evolution and Statistical Physics
One can expect that there is a relation between virulence and transmission: For very small virulence, the parasite density in the host is low, and so is the transmission rate.
Biological Evolution and Statistical Physics
The same authors also studied a different model [173], where the more virulent strains do coexist with the less virulent strains within the same host without replacing them, but where the virulence perceived by the host is its most virulent parasite.
Biological Evolution and Statistical Physics
In this case, the long-term winners are those parasite strains that have a virulence close to the maximum possible value for which R0 is still larger than 1. A different formal approach which combines within-host and between-host selection was taken by Frank [174].
Biological Evolution and Statistical Physics
This fixed point was found by maximizing the basic reproductive rate R0 (for the parasite) or the number y∗ of infected individuals (for the host).
Biological Evolution and Statistical Physics
Models of this type usually contain one or a few loci with several alleles for the host, and a matching number of genotypes for the parasite.
Biological Evolution and Statistical Physics
Furthermore, it is assumed that each host genotype is matched by a parasite genotype so that the host fitness is minimal if the frequency of its matching parasite is 1, and the parasite fitness is maximal if the frequency of its matching host genotype is 1.
Biological Evolution and Statistical Physics
Finally, a small mutation rate is included which randomly changes the genotype of an individual host or parasite. A particularly transparent discussion of such a model is given by Seger [177].
Biological Evolution and Statistical Physics
Some scientists believe that the main use of sexual reproduction is to evade parasites.
Biological Evolution and Statistical Physics
Recombination can quickly create new genotypes which might be better at resisting the parasite.
Biological Evolution and Statistical Physics
In the presence of mutations, the most successful parasite genotype is determined by the local spatial pattern and is different for spirals and for turbulence.
Biological Evolution and Statistical Physics
How can observations discriminate between these various models? As it turns out, every physical frequency model predicts its own ’fingerprint’ set of parasitic, weaker frequencies in addition to the strong ones it set out to explain in the first place (e.g., Miller et al. 1998a).
