Apis mellifera; co-evolution; honey bee; host; parasite; Varroa destructor1. Introduction Coevolution is a dynamic process driving the interactions between parasites and hosts [1,2,3]. Such dynamics can vary across generations depending on specific selection scenarios [3]. As parasites are ...
Host–parasite coevolution is considered to be an important factor in maintaining genetic variation in resistance to pathogens. Drosophila melanogaster is naturally infected by the sigma virus, a vertically transmitted and host‐specific pathogen. In fly populations, there is a large amount of genetic...
Host-Parasite Coevolution: Evidence for Rare Advantage and Time-Lagged Selection in a Natural Population In theory, parasites can create time-lagged, frequency-dependent selection in their hosts, resulting in oscillatory gene-frequency dynamics in both the hos... DCM Lively - 《Evolution》 被引量...

We investigate the host-parasite coevolution with mutation in a single-locus system. We use the single-locus quasi-species model with a frequency-dependent fitness landscape and find the phase diagrams for given sets of evolution parameters by means of a linear stability analysis and numerical ...
We modeled coevolution (a) when hosts are exposed to a single parasite species that must genetically match the host to infect, (b) when hosts are also exposed to a generalist parasite that increases fitness costs to the hosts, and (c) when coinfecting parasites compete for the shared host...

Host–parasite coevolution is a key driver of biological diversity and parasite virulence, but its effects depend on the nature of coevolutionary dynamics over time. We used phenotypic data from coevolving populations of the bacterium Pseudomonas fluorescens SBW25 and parasitic phage SBW25Φ2, and ...
In this paper, we extend a model of host-parasite coevolution to incorporate the semiconservative nature of DNA replication for both the host and the parasite. We find that the optimal mutation rate for the semiconservative and conservative hosts converge for realistic genome lengths, thus maintainin...
The spatial structure of hostparasite coevolution is shaped by population structure and genetic diversity of the interacting species. We analysed these population genetic parameters in three related ant species: the parasitic slavemaking ant Protomognathus americanus and its two host species Temnothorax...
