Sentence examples for ensuring persistence from inspiring English sources

The model predicts that core vaccination campaigns, using vaccines that provide two years of immunity, and targets 30 40% of individuals within a population every 1 2 years would be successful in ensuring persistence of small populations, and required coverage levels can be even lower in larger populations.

For this reason, whilst plasticity may offer an important stopgap measure for populations facing environmental change, evolutionary adaptations over multiple generations will still be essential for ensuring persistence into the future (Bradshaw and Holzapfel 2006), especially when environmental change occurs over a large area and long period of time (e.g. climate change; Lynch and Lande 1993).

Cao et al. (pp. 171 179 ) investigate the cold desert shrub Kalidium gracile (Amaranthaceae) and find that it has three life history traits that help ensure persistence at a site: a polycarpic perennial life cycle, a persistent seed bank and dormancy cycling.
