Sentence examples for strength of barriers from inspiring English sources

Population boundaries are largely determined by local environment, the strength of barriers to migration, and the organism's inherent dispersal abilities.

Accordingly, the lower perceived behavioural control over exercise in pregnancy in the Chinese women suggests differences in the types or strength of barriers to exercise between cultures.

For example, effectiveness trials might demonstrate the potential for a skewing of beneficial impacts among various population sub-groups (e.g., differential uptake across social strata; variegations in the number and strength of barriers to access along the social gradient) [ 22, 44].

Patients with a high ABQ score (above the median of 25), which indicates an increased number of existing adherence barriers and/or a high strength of these barriers, were significantly (p < 0.005, Pearson Chi-Square) more likely to have a poor anticoagulation quality than patients with a low ABQ score (44.6% versus 27.3%).

Since reproductive barriers act in a sequential order, early-acting barriers (such as those that cause transmission ratio distortion) have the potential to be more effective at restricting gene flow than later acting barriers, even if the absolute strength of the barriers is the same [ 8, 61, 67- 69].
