New data collection efforts within the framework proposed here should be designed so as to make progress at understanding the role of migration in population health patterns.
θ 1 = effective size of population 2, θ 2 = effective size of population 2, θ a = effective size of ancestral population, m 1 = migration into population 1 from population 2, m 2 = migration in to population 2 from population 1, τ = splitting time between populations.
We did this to examine whether or not the parasite population had become more subdivided due to the pronounced effect of genetic drift and migration in declining populations.
Surprisingly, a negative slope was obtained in the case of the mtDNA, reflecting a major effect of isolation and genetic drift versus migration in certain populations of the Mediterranean area.
The availability of a large number of detected SNPs provides sufficient markers to study mallard population structure and migration in a population genetic framework.
Nor it is correct to say that the birth rate is more crucial than net migration in determining population growth.
Willemoes, M. et al. Narrow-front loop migration in a population of the common cuckoo cuculus canorus, as revealed by satellite telemetry.
In a broader context, our results on two connected bacterial populations can be viewed as the first step in a bottom-up approach aimed at probing the role of migration in the population dynamics of more complex networks.
