Sentence examples for ecological selection from inspiring English sources

In contrast, morphological or behavioral traits under more limited ecological selection, for example, sexually selected traits, might be more likely to diversify into a broader array of forms and show less propensity for convergence [ 11].

Ecological selection occurred at this stage and the probability that the seedling survived varied according to the ecological selection function described above.

Strong ecological selection also increases the frequency at which hybrid species form.

The external barriers are thought to result from ecological selection and niche differentiation among lineages.

Fifty replicates were run at each combination of hybrid fertility (r) and ecological selection (s) parameters.

In addition, the genetic integrity of incipient hybrid species is increased by stronger ecological selection (Fig. 3).

For hybrid speciation to occur at an appreciable frequency in our model, relatively intense ecological selection was required.

The frequency of simulation replicates ending in hybrid speciation increased with greater hybrid fertility (r) and stronger ecological selection (s; Fig. 2).

With strong ecological selection and low hybrid fertility, GST values decayed at a slower rate and were higher after 1000 generations than in replicates with weaker selection.

At each of eight combinations of geographical isolation and hybrid fertility (r) parameters, 50 replicate simulations were run (ecological selection parameter fixed at s=0.9).

In simulations with the most extreme ecological selection (s=0.9), some replicates ended after 4000 generations without ecological introgression or hybrid speciation.
