Tradeoff between short-term and long-term adaptation in a changing environment | Robert Forster

Wilke (UT Austin, Caltech | Abstract: | We investigate the competition dynamics of two microbial or viral strains that live in an environment that switches periodically between two states. One of the strains is adapted to the long-term environment, but pays a short-term cost, while the other is adapted to the short-term environment and pays a cost in the long term. We explore the tradeoff between these alternative strategies in extensive numerical simulations, and present a simple analytic model that can predict the outcome of these competitions as a function of the mutation rate and the time scale of the environmental changes. Our model is relevant for arboviruses, which alternate between different host species on a regular basis. | Source: | arXiv, q-bio.PE/0412029 | Other source: | [GID 606117] pmid16383435 | Services: | Forum | Review | PDF | Favorites |
