Sentence examples for more recent radiation from inspiring English sources

In the latter case, the most extensively used models are the gravity model [15, 16] and the more recent radiation model [6].

There are, currently, two main estimation methods which are used within the literature: the widely used gravity model (e.g. [14, 23, 24]), and the more recent radiation model [25].

Divergence dates estimated in the concatenated multilocus analysis support the initial radiation of Melanohalea during the Oligocene, ca. 30.5 (95% HPD = 23.8-38.1) Ma, while divergence estimates from the multilocus species tree approach suggests a more recent radiation during the Oligocene-Miocene boundary, ca. 23.7 (95% HPD = 19.4-27.9) Ma (Table  3).

We think that differences in the rate of evolution among subgroups of the North African U6 haplogroup [ 40] could be better explained by the same pattern assuming that the U6a subclade, with the highest coding/regulatory ratio, had a more recent radiation than the U6b subclade.

First, some apparent geographical separation between the SWA and SEA groups that requires more intense sampling in the Old World to provide a true characterization of this relationship, and then a more recent radiation of the SWA and SEA groups into the New World most likely within the last 25 years (Halbert & Núñez, 2004).

Following climate-driven dysoxic mass extinctions in the deep sea, shallow-water organisms have recolonised the deep sea and the extant deep-sea fauna appears predominantly to comprise both ancient and more recent radiations of shallow-water lineages.

However, examples of origination of higher taxonomic levels in the deep sea are relatively few, and the extant deep-sea fauna is considered to result predominantly from both ancient and more recent radiations of shallow-water lineages into deep water (Horne, 1999; Wilson, 1999).

The fact that the latter 51 bp region is missing in S. salar and is retained in O. tshawytscha and O. nerka suggests that a common ancestor to these latter two species diverged well before the more recent salmonid radiation.

Analysis of mstn2b structure in particular also suggests that a common ancestor to Oncorhynchus tshawytscha (a.k.a. king or chinook salmon) and O. nerka (a.k.a. sockeye salmon) diverged early and before the more recent salmonid radiation.

However, it is worthwhile to mention that the more recent concern about radiation exposure has stimulated a focus on dose saving techniques.

In addition, the initial divergence within the NA OPXV appears to have occurred much earlier than the apparently more recent and/or rapid radiation of known Old World OPXV.
