Sentence examples for patterns of speciation from inspiring English sources

In contrast, more loosely associated species may have quite different patterns of speciation, indicating 'jumps' to unrelated hosts (Fig. 2b).

Cospeciation is not a prediction of coevolution, but there are some circumstances where we would expect to find matching patterns of speciation.

We also discuss the role transposable elements may have had in generating genomic variation and a potential link between transposable element proliferation and patterns of speciation.

Suppose that patterns of speciation are entirely random with respect to the direction of a trend… Differential extinction can move a cladal mode anywhere within the spectrum of variation among species.

The importance of extinction in shaping global diversity patterns is increasingly well documented, but the phylogenetic legacy of past extinctions on regional faunas is often disregarded even though it can be as important as patterns of speciation in shaping modern diversity trends.

These models test several types of alternative patterns of speciation and extinction through time [ 38].

Second, the pattern of speciation seems to have begun in the same way, for the same dozen initial places are found in this species, too.

In b, which reflects a pattern of speciation known as "punctuated equilibria," most morphological change occurs in association with speciation events, and the trend is said to be cladogenetic because change occurs primarily among species, not within them.

Thus, trees provide information about the pattern of speciation (the formation of new species) and, in turn, this pattern can be used to infer how coevolution has shaped the evolutionary paths of species.

In contrast with the pollination interactions discussed above, a comparison of the pattern of speciation in beetles and host plants shows that there is little evidence for cospeciation and that host shifts have occurred frequently (Becerra 1997).

Nevertheless, the basic pattern of speciation into a primarily lowland species and a specialist upland species is present.
