Optimization Using a Host-Parasite Model with Variable-Size Distributed Populations
|This paper presents a model of coevolution between two variable-size, spatially distributed populations, evolving in an environment with a ow of resources. The two populations have a host-parasite relationship where the host species is dependent on the uptake of resources from the environment for their reproduction. The parasites seek to \infect" host organisms and parasitize on their resource...
متن کاملA statistical test for host-parasite coevolution.
A new method, ParaFit, has been developed to test the significance of a global hypothesis of coevolution between parasites and their hosts. Individual host-parasite association links can also be tested. The test statistics are functions of the host and parasite phylogenetic trees and of the set of host-parasite association links. Numerical simulations are used to show that the method has correc...
متن کاملAdaptation, specificity and host-parasite coevolution in mites (Acari).
Parasitism by mites is widespread and involves all the classes of vertebrates, from fishes to mammals. Owing to their small size and their great plasticity, mites are able to adapt to a wide range of habitats. Most of the species are ectoparasites but endoparasitism, especially in the respiratory tract, is common in birds and mammals. The morphological modifications appearing during the process...
متن کاملSex differences in host defence interfere with parasite-mediated selection for outcrossing during host–parasite coevolution
The Red Queen hypothesis proposes that coevolving parasites select for outcrossing in the host. Outcrossing relies on males, which often show lower immune investment due to, for example, sexual selection. Here, we demonstrate that such sex differences in immunity interfere with parasite-mediated selection for outcrossing. Two independent coevolution experiments with Caenorhabditis elegans and i...
متن کاملCoevolution of parasite virulence and host mating strategies.
Parasites are thought to play an important role in sexual selection and the evolution of mating strategies, which in turn are likely to be critical to the transmission and therefore the evolution of parasites. Despite this clear interdependence we have little understanding of parasite-mediated sexual selection in the context of reciprocal parasite evolution. Here we develop a general coevolutio...
