Sentence examples for high levels of speciation from inspiring English sources

Knowing that several speciation events have occurred in Chthamalus after the closure of the Panamanian Isthmus (C. proteus−C. fragilis, and the divergence between the TEP species and the C. fissus−C. anisopoma pair, and divergences within each of those clades) suggests high levels of speciation in the Pleistocene.

Teixeira, M. M. et al. Phylogenetic analysis reveals a high level of speciation in the Paracoccidioides genus.

Given their position in the topology and our understanding of trans-Isthmian relationships, high level of speciation must have taken place in the Pleistocene in the tropical eastern Pacific.

Genomes of such hybridizing species may be expected to exhibit a mosaic structure, with high levels of divergence restricted to "speciation islands," which contain the loci responsible for species differences (Wu 2001).

Alternatively, the observed morphological divergence but lack of genetic structure is consistent with strong character specific selection in the presence of high levels of gene flow or incipient speciation.

Nonetheless, it is clear that a PSC classification of heliconiines would result in even lower levels of overlap, implying higher levels of allopatric speciation than under BSC classifications (Fig.  2).

Under this graphical representation, CYB3 appears extremely saturated (slope S = 0.02), suggesting that high levels of nucleotidic saturation may be reached for speciation events more recent than 5 10 Ma.

Since it is generally assumed that such a long planktonic larval duration should promote high levels of gene flow and effectively counterbalance the speciation process [ 15, 16], life history traits make spiny lobsters a suitable model for better understanding the speciation process in marine organisms with large dispersal capabilities.

High levels of dispersal, associated with interbasinal invasions, reduced opportunities for allopatric speciation.

The speciation loss can be attributed to the high levels of species invasions present at this time (Stigall 2012a, b).

Because of the high levels of interest in cichlid fishes as model organisms in which to investigate speciation processes, non-cichlid flocks have been largely overlooked.
