Sentence examples for maintain divergence from inspiring English sources

Our analysis shows that (a) the infection polymorphism is stable below a critical migration rate, (b) an (initially) uninfected "island" can better maintain divergence at a selected locus (e.g. can adapt locally) in the presence of CI, and (c) unidirectional CI selects for premating isolation in (initially) uninfected island populations if they receive migration from a Wolbachia-infected mainland.

Significant phenotypic differentiation between genetically similar (in terms of neutral variation) populations suggests that mate choice can maintain divergence at sexually selected traits despite gene flow.

This has lead to the hypothesis that species- and population-level differences in opsin gene sequence and expression represent adaptations for foraging in either turbid or clear water and that these differences in spectral sensitivity may drive and/or maintain divergence in male coloration via sexual selection [ 11].

Once divergent mating preferences evolve, they may constitute a powerful mechanism maintaining divergence in sexual traits.

A similar pattern of differentiation between chromosome arrangements that we have observed here has been found in other studies [ 23, 25], whose authors have argued that such patterns arise through directional selection maintaining divergence between chromosome arrangements at specific loci in the face of genetic exchange between them.

Teshima and Innan [ 7] have suggested that such regions of differentiation in the face of on-going gene conversion can be a signal that selection is maintaining divergence in the paralogs (i.e. the paralogs have begun the process of neofunctionalization).

In this paper, we used a model similar to that of Telschow et al. [ 28] to investigate how CI contributes to maintaining divergence between two populations which have undergone different selection regimes, but after which nuclear genes and Wolbachia can be exchanged.

The new strategy is to construct artificial diffusion terms in a physically-consistent manner, such that the artificial terms act as a diffusion term only in the curl of magnetic field to capture numerical discontinuities in the magnetic field while not affecting the divergence field (thus maintaining divergence-free constraint).

Arguably, in the absence of better information, a prudent conservation strategy is to maintain population divergence generally until the specific targets of selection can be identified through further research.

A combination of natural and sexual selection appears to maintain phenotypic divergence between populations, but especially between those using different types of spawning habitats (e.g., beaches and tributaries: [ 20, 21]).

An approximate MHD Riemann solver, an approach to maintain the divergence-free condition of magnetic field, and a finite difference scheme for multidimensional magnetohydrodynamical (MHD) equations are proposed in this paper.
