Sentence examples for duration of bottlenecks from inspiring English sources

Then, we used an ABC framework to identify the most probable among different colonization scenarios and to infer several key parameters of the foundation history of olives in East Australia and Hawaii (e.g. duration of bottlenecks, effective number of founders).

The duration of bottleneck (db) was set at a maximum of 300 generations (1200 years).

Another attribute of the long-term viability of populations is the ability to recover from population 'bottlenecks', which is directly related to the intrinsic rate of population growth and duration of bottleneck.

The relative size of the bottleneck and duration of the bottleneck were confounded as suggested by a previous study (Eyre-Walker et al. 1998).

The severity and duration of the bottlenecks will determine the amount of diversity loss (Bickham et al. 2000).

The severity of the bottleneck (k), defined as the ratio of the population size during the bottleneck (Nb) to the duration of the bottleneck (d), was set at 1.2, since in maize it has been estimated by several groups to range from 2.0 [22] to 4.5 [17].

The primary parameter of interest is bottleneck severity k, which is the ratio of the size of bottlenecked population Nb to duration of the bottleneck d in generations (Fig. 2B).

First, our model simulation suggests a small size of the domestication bottleneck but also a relatively short duration of the bottleneck, which implies a limited reduction in genetic diversity.

The effect of such bottlenecks depends upon the effective size of the ancestral population, its initial variation, the duration of the bottleneck, and the nature of the marker under study.

However, the duration of the bottleneck T B was also much shorter than the period of exponential growth T after the bottleneck: T B = 0.0113 T (95% CI: 0.0054 - 0.0195 T), which may limit the loss of genetic diversity.

Regarding the 'latency phase' or duration of the bottleneck, the results are difficult to interpret.
