The effect of migration on local adaptation in a coevolving host–parasite system
TL;DR: It is shown that patterns of local adaptation have considerable temporal and spatial variation and that, in the absence of migration, parasites tend to be locally maladapted, but in accord with the model, parasite migration results in parasite local adaptation, but host migration alone has no significant effect.
Journal ArticleDOI
Host–parasite coevolutionary arms races give way to fluctuating selection
Alex R. Hall,Pauline D. Scanlan,Andrew D. Morgan,Andrew D. Morgan,Angus Buckling,Angus Buckling +5 more
TL;DR: Phenotypic data from coevolving populations of the bacterium Pseudomonas fluorescens SBW25 and parasitic phageSBW25Φ2 and genetic data from the phage tail fibre gene are used to show that arms race dynamics, typical of short-term studies, decelerate over time.
Journal ArticleDOI
Differential impact of simultaneous migration on coevolving hosts and parasites.
Andrew D. Morgan,Andrew D. Morgan,Michael A. Brockhurst,Laura D. C. Lopez-Pascua,Csaba Pál,Angus Buckling +5 more
TL;DR: The results suggest that simultaneous migration of hosts and parasites can dramatically affect the interaction of host and parasite, and the organism with the lower evolutionary potential may gain the greater evolutionary advantage from migration.
Journal ArticleDOI
Population mixing accelerates coevolution
TL;DR: This work experimentally tested the prediction that mixing in spatially structured populations of hosts and parasites can increase the rate of antagonistic coevolution by allowing populations of bacteria and parasitic bacteriophage to coevolve in mixed and unmixed microcosms.
Journal ArticleDOI
Estimate of the Spontaneous Mutation Rate in Chlamydomonas reinhardtii
TL;DR: In this article, the authors present a direct estimate of the mutation rate and a description of the properties of new spontaneous mutations in the unicellular green alga Chlamydomonas reinhardtii.
