Sentence examples for demographic persistence from inspiring English sources

Anyway, a speedier strategy seems to fit stories set in the American West, where demographic persistence is limited and society fluid.

Some studies have, however, shown phylogeographic results strongly supporting demographic persistence in areas supposedly covered by ice [ 39].

In addition, the objective of maintaining the evolutionary potential of species or populations may be inadequately served by current management actions primarily aimed at preserving or resurrecting small populations – which (often unwillingly) impose artificial-selection regimes in their efforts to ensure demographic persistence and/or the maintenance of genetic variation (Kinnison et al. 2007).

Important modifications could already be introduced to the operational goals of conservation programmes, which emphasize demographic persistence and the preservation of (all) genetic variation in ways that are not always compatible with fostering adaptation to current conditions (Stockwell et al. 2003, 2006).

The demographic, enrollment, persistence, graduation, employment and financial aid numbers don't match their optimism.

Contemporary dispersal of large numbers of larvae is important for the demographic recovery and persistence of populations and often operates over local scales (Gaines et al. 2007).

Given the nation's demographic trends -- and the persistence in stereotyped thinking about older people -- there is every reason to believe that the age-bias complaints from television writers and teachers, bus mechanics and bankers will continue their explosive growth.

Despite widespread concerns among conservationists about shrubland birds, much is still poorly understood regarding fundamental demographic processes associated with the persistence of species in dynamic landscapes, such as the age of colonists, their success upon establishment, the fate of birds displaced by disturbance, and the effect of displaced birds on neighboring territories.

Essentially the question becomes, will populations evolve demographic characteristics that will enable persistence before the population goes extinct [27]?

We used multiple-generation, individual-based data to develop and parameterize a size-class and location-based population projection model, allowing us to test effects of fragmentation on population dynamics at local (i.e., subpopulation) and system-wide (i.e., metapopulation) scales, and to identify demographic rates which influence the persistence of isolated and fragmented populations.

We used these data to develop and parameterize size-class and location-based population matrix projection models, allowing us to test effects of fragmentation on population dynamics at local and network-wide scales, and to identify demographic rates which influence the persistence of isolated and fragmented systems.
