Sentence examples for geographic contact from inspiring English sources

But a new study in Nature Climate Change predicts that the overall occurrence of these hybridization events between closely related species will actually be relatively low: On average, only 6.4% of species are expected to come into geographic contact with a hybridization possibility by the end of the century.

Bayesian assignment using multilocus genotype suggests that the proportion of hybrids varies in different geographic contact sites of Q. liaotungensis and Q. mongolica (Table 6 and Fig. 6).

In contrast to allopatric scenarios, the two host species are sometimes distributed in adjacent patches that are in direct geographic contact with one another.

These clades are allopatrically distributed, except in the region where the Central Coast and Santa Cruz Mtns clades are parapatric, coming into close geographic contact and perhaps overlapping slightly.

If this is also true in gulls, and our present data seems to support this, it could mean that marinus, after a period of allopatric divergence, has had a relatively long history of geographic contact with closely related taxa which facilitated the perfection of reproductive barriers through reinforcement multiple times.
