The Geographic Mosaic of Sex and the Red Queen
The maintenance of sexual reproduction in natural populations is a pressing question for evolutionary biologists. Under the "Red Queen" hypothesis, coevolving parasites reduce the reproductive advantage of asexual reproduction by adapting to infect clonal genotypes after they become locally common. In addition, the "geographic mosaic" theory of coevolution proposes that structured populations o...
متن کاملHost-parasite Red Queen dynamics with phase-locked rare genotypes
Interactions between hosts and parasites have been hypothesized to cause winnerless coevolution, called Red Queen dynamics. The canonical Red Queen dynamics assume that all interacting genotypes of hosts and parasites undergo cyclic changes in abundance through negative frequency-dependent selection, which means that any genotype could become frequent at some stage. However, this prediction can...
متن کاملParasite local adaptation: Red Queen versus Suicide King
Parasites are generally expected to be locally adapted to their hosts, but the basis of this prediction involves two distinct areas of research: coevolutionary studies of infectivity and epidemiological studies of optimal virulence. The distinction between infectivity and virulence is sometimes blurred but is crucial to our understanding of parasite local adaptation. Recent theoretical and empi...
متن کاملEcological and Evolutionary Oscillations in Host-Parasite Population Dynamics, and The Red Queen
In a host-parasite system, the constitutive interaction among the species, regulated by the growth rates and functional response, may induce populations to approach equilibrium or sometimes to exhibit simple cycles or peculiar oscillations, such as chaos. A large carrying capacity coupled with appropriate parasitism effectiveness frequently drives long-term apparent oscillatory dynamics in popu...
متن کاملRacing the Red Queen
Despite the discovery of antibiotics almost a century ago, infectious diseases continue to be a substantial cause of human mortality and morbidity worldwide, especially in developing countries. The adverse affects of infectious diseases are thought to increase over the coming years as the widespread misuse of antibiotic leads to the emergence of strains for which current therapies are ineffecti...
