Sentence examples for variation or migration from inspiring English sources

If neutral evolution is frequently acting in emergent patterns, as in the case of mutational variation or migration, both the emergence and the advantage of certain combinations are emphasized by the bacterial exposure to variable environments.

Studies on adaptive variation take on urgency with restoration in changing climates, as it becomes imperative to predict how ecotypes within species may respond to climate change, either through plasticity, adaptive variation, or migration (Nicotra et al. 2010).

Surrogates of traffic exposures such as road proximity and traffic density, although capturing some of the variation in local traffic environments, do not capture the actual temporal and spatial variations or migration and degradation profiles of the actual pollutant mix that originates from roadways that may be the underlying causal agents for adverse health effects.

No more evolution will occur until mutation or migration creates variation at the locus again.

Estimates of migration rates (individuals per generation) between genetically-delimited populations appear to be mostly congruent with features of the landscape, with variation among migration rates associated to migratory barriers or conduits.

While previous studies have documented variation in migration direction through the Strait of Georgia among species or populations [2], [3], we found intra-population variation among individuals, in three different species.

There is much variation in migration patterns, between and within species, and even within (breeding or wintering) populations of the same species [ 2– 3].

In our study, the dependence of neuronal growth (neurite length, guidance, or migration) on the steepness of chemotactic gradient was examined by fitting a linear model for the neuronal growth parameters (e.g. length, guidance, and migration) and gradient steepness variation (slope-based measure, log-transformed).

Fourth, given the variation of migration policy changes along migrant categories, DEMIG POLICY identifies and codes the migrant group targeted by each policy measure.

However, in general the −HA group migrated more than the +HA group, and we found a significant larger variation in migration pattern in the −HA group.

The authors analyze international migration flows using a gravity model and find, contrary to this study, that non-economic measures of quality of life, including the happiness index, do not explain the variation in migration flows toward 16 OECD countries.
