Sentence examples for selection on host from inspiring English sources

Selection on host modifiers is sexually antagonistic in that, conversely, host mutants that enhance Wolbachia in females are favoured whereas suppressors are not.

Due to the high costs of parasitism, there should be strong disruptive selection on host egg phenotypes followed by selection on cuckoos due to high rejection rates of non-mimetic eggs by the parrotbills.

We believe that our understanding about the role of parasitism in host speciation will be improved by studying the mechanisms of how parasites might cause divergent selection on host traits.

Firstly, in the context of egg phenotype coevolution, cuckoo eggs that are outside the trait space of the host are likely to contribute little to selection on host egg appearance, because such eggs are nearly always rejected by both hosts, irrespective of the host's own egg type.

In the present study, we have shown that cuckoos specializing on bramblings have evolved egg colors that are close to maximizing acceptance rate of their eggs, and that this in turn creates ample opportunity for disruptive selection on host egg color.

However, examples of parasite-mediated selection on host populations are limited.

These additional interactions have the potential to impose selection on hosts and parasites and influence the patterns and processes of their evolution.

Selection on hosts and symbionts should thus converge toward improved transmission.

In theory, contrasting parasite communities in different foraging habitats could generate divergent selection on hosts and promote ecological speciation.

Furthermore, selection on hosts for evolving discriminating abilities is strong, because successful parasitism always leads to a complete loss of reproductive output for the host.

Such Wolbachia adaptations could result in very high symbiont-mediated transmission rates that, in turn, would weaken selection on hosts for reduced sperm modification.
