Sentence examples for increase the speciation from inspiring English sources

Increased densities increase the speciation rates probably because increasing the number of candidate males within the mating area of a female increases the effectiveness of female choice [ 72].

Lower levels of pollen movement could lead to greater spatial genetic structure and increase the chance of speciation via allopatric speciation in bee-pollinated taxa compared to bird-pollinated taxa.

However, we still do not know whether or how genome duplication might increase the rate of speciation or increase the likelihood of evolutionary innovations.

The most likely mechanism by which host expansions can increase the likelihood of speciation is that they allow the insect to gain a wider geographic distribution [ 50] and thus put it in a situation where genetic fragmentation is more likely.

Both extensions of the original model thus increase the likelihood of competitive speciation.

Pollinator transfer between different Ficus species should increase the tendency for post-speciation introgression between host lineages [ 9] and presumably influence the evolution of fig wasp and host fig phenotypes.

However, while these phylogenetic tests reveal an association between rates of evolution and number of phylogenetic nodes, they are not able to localise those changes to the nodes rather than the edges of the phylogeny, so cannot distinguish between two alternative explanations, that speciation events increase the substitution rate or that higher substitution rate increases diversification.

Importantly, the increase in the speciation rate with increasing habitat size is not due to an increased opportunity for isolation by distance because the axis of increased opportunity for isolation by distance was perpendicular to the selection gradient along which incipient species diverged.

For instance, a large amount of variation among individuals allows a species to rapidly adapt to new habitats, lessening the chance of it going extinct, while a wide geographic range increases the chance of speciation, by making it more likely that part of the population will become isolated.

In summary, CpG-sites were excluded for fitting the sequence data to the evolutionary model that we used, heterogeneity of mutation rates among lineages was assumed in each locus for considering the variation in mutation rates in hominids, and four species were applied for increasing the inner-node speciation.

(Conversely, the diversity of species in a clade can increase either because the speciation rate increases or the extinction rate decreases).
