Sentence examples for ancestral limits from inspiring English sources

Niche conservatism - the tendency of species to retain ancestral limits in tolerances to environmental factors - has a long history [ 1, 2].

Specifically, we take the limit N → ∞, with time rescaled by N, to test whether the ancestral limit process converges to Kingman's coalescent.

However, Sánchez Meseguer et al. [ 38] employed a Bayesian approach [ 39, 40] that limits ancestral areas to only single states in the reconstruction (i.e. it is not possible to infer the occurrence of ancestral populations in multiple areas).

It is the limiting ancestral process for a diverse array of population models [20], [21].

Unlike other biogeographic inference methods based on a strict vicariance model [138] [140], DIVA does not restrict widespread distributions to terminals or limit ancestral distributions to single areas [137].

It must also be true that pairwise coalescent events dominate the limiting ancestral process (Möhle and Sagitov 2001).

Because of the large surface of each area (continent-level areas), the maximum number of ancestral areas was limited to two.

In Figure 3 the sample is assumed to start in state 1, which may be considered the farthest from the transient equilibrium (state 5) of the limiting ancestral process.

From Figures 2 and 3, we conclude that the limiting ancestral process for a sample of size n = 4 should be quite accurate as long as the population size is > ∼100.

Similarly, Lee and co-workers [ 80] suggested limited ancestral reconstruction was possible, although they suggested that six Ig3 exons and two Ig7 exons were present in the insect ancestor.

We investigate the accuracy of two key features of the limiting ancestral process: that coalescence events occur predominantly between pairs of lineages and that the majority of the ancestral process before coalescence is spent in state 5 (i.e., with all lineages in separate individuals, making them exchangeable).
