Rhythmic natural selection over intertidal and brackish water genotypes simple formulations for testing hypothesis
Tidal cycles at benthic habitats induce a set of periodic environmental changes in variables like salinity, temperature and sediment water content which are able to stress benthic organisms. Consequently, a natural selection temporally correlated with tides affects the fitness of genotypes [wi] depe...

| 520 | |a Tidal cycles at benthic habitats induce a set of periodic environmental changes in variables like salinity, temperature and sediment water content which are able to stress benthic organisms. Consequently, a natural selection temporally correlated with tides affects the fitness of genotypes [wi] depending on their adaptation degree. Classic population genetics demonstrate that [1] rhythmic wi is more restrictive than equivalent spatial variations to preserve genetic variance, and [2] mean fitness of the population [w-] does not have to be enhanced by genetic variance [?2 w]. The present study develops a simple replicator dynamics-based model of continuous selection, where wi of multiple asexual genotypes fluctuates as a sinusoid. The amplitude of w was set as 0.5 [1-wmin], whereas the ratio of tide period to generation time [h] was defined. Overall, the model shows that if h greater than 1, then the success of an advantageous genotype is exposed to randomness, and w- may decrease over generations. In contrast, if h less than 1 the success is deterministic, is limiting co-dominance, and only depends on wmin. The amount of different genotypes buffers the decay of ?2 w and hence increases cohesiveness. Finally, the reliability of the model is analyzed for a set of target intertidal and brackish water organisms. | ||
