Sentence examples for wave dispersal from inspiring English sources

Rather they fit better a two wave dispersal model for the settlement of the New World.

For maize, long-distance gene flow after the first wave of dispersal seems to be due to relatively recent (colonial and post-colonial) migration and trade [64].

Also, if genetic data for archaeological crop remains become available, it should become possible to obtain a clearer genetic signal of the first wave of dispersal, which would then help to distinguish it from the changes that occurred after this first wave (local divergence, foreign introductions, and hybridization).

However, as long as the pattern is mainly due to the initial wave of dispersal and not to subsequent long-distance gene flow events or introgression from wild relatives, the net effect of these subsequent demographic events will be to decrease heterozygosity locally.

Overall our study supported the one wave, rapid dispersal theory of modern humans along the Asian coast.

Nonetheless, among the genera that may have been included in this wave of dispersal were the earliest representatives of Lutra (which may represent Lontra, given that New World river otters have been reclassified into Lontra) and Mustela, both of which are first recorded in North America from the Late Miocene to Early Pliocene (~5.9-4.6 MYA [ 19]).

The relatively high spatial variation and the radial distribution pattern from the river mouth in PC1 strongly suggest that the PC1 value represents the sediment supply from the Kushida River and the dispersal by waves or tidal currents (Fig. 6).

In contrast, a wave-like model of dispersal of RYMV, which postulates its initial diversification in East Africa, followed by westward spread across the continent, was developed, refined and dated.

The population history within lineage A2 has been more complex, potentially due to waves of colonisation or dispersal among regions associated with the expansion of grassland and savanna habitats.

Whereas AFLP data for the first time demonstrated the genetic cohesion of some Tropheus taxa, the mitochondrial data provided details about the colonisation history of the genus Tropheus and revealed multiple waves of diversification and dispersal (see also [ 27]).

This paper is concerned with the minimal wave speed in a nonlocal dispersal predator prey system with delays.
