Sentence examples for estimates of migration from inspiring English sources
Similar observations were made in previous studies17,18, where IMa estimates of migration were, at some instances, two orders of magnitude lower than those obtained with Migrate-n.
Estimates of migration rates (M = m/μ, where m is the fraction of the new immigrants in the population per generation and μ is the mutation rate of the gene) were obtained with the program MIGRATE v. 3.2.755.
From a broader perspective, our data show that analysing gene flow in a domestic species as goats, where population splitting times are intrinsically short, without taking into account the contribution of isolation may lead to inflated estimates of migration rates.
Geoffrey Dabelko, who heads the Environmental Change and Security Program at the Woodrow Wilson Center and was not directly involved with the research, said the report demonstrated that previous estimates of migration are nothing more than "very fuzzy aggregate global figures that have weak to no methodology behind them".
The corresponding IV estimates of migration effects are reported in Table 4.
Subsequently, storylines are operationalized, leading to scenario estimates of migration pressure up to 2035.
We carried out sensitivity analyses to assess the impact of various scenarios on our overall estimate of migration.
We then develop an approximate extension of this to the structured case to provide a joint estimate of migration rate and spatially varying selection coefficients.
First, a measure of genetic structure never easily translates into an estimate of migration rate (Whitlock and McCauley 1999; Marko and Hart 2011).
For example, even with high statistical power (no type II error), accepting a 5% type I error for detecting migrants can spuriously increase the estimate of migration rate.
An FST of 0.54 will therefore likely be obtained for a proportionally higher number of migrants (as there is more drift within populations) than under an equilibrium model, making our estimate of migration upwardly biased.
