Polymorphic Loci

Four natural Amazonian Anopheles darlingi populations were analyzed for 19 loci, 12 of which showed variation, i.e., 68.4% of polymorphic loci. The Ariquemes, Rondônia, population was the most variable, with a large number of alleles per locus (2.26 ± 0.27) and high polymorphism (P = 63.15). The highest values of observed and expected intralocus heterozygosity were observed in the Manaus, Amazonas, population (Ho = 0.432 ± 0.11; He = 0.375 ± 0.08), and the lowest in the Cachoeira Porteira, Pará, population (Ho = 0.236 ± 0.09; He = 0.290 ± 0.11). Wright's F-statistic revealed disequilibrium caused by an excess of homozygotes, as shown by the Fis > Fst values (Fis = 0.083 > 0.026) reflecting intrapopulational differentiation. The four populations studied were genetically similar, as indicated by distance and similarity values. Chromosomal variation of Amazon population also did not indicate geographical differentiation, and populations in the central region of the Amazon Basin showed high polymorphism in relation to the marginal populations, which were mainly monomorphic.

Migrant Groups

Abstract The distribution of international migrants is an essential part of socio-geographical differentiation. In addition to international migration, internal or domestic migration plays an important role in the geographical distribution of immigrants. Based on data from the population register, the Census, and a quantitative survey, we analysed the internal mobility of Ukrainian and Vietnamese immigrants, which are the first and third largest international migrant groups in the Czech Republic. Using the assimilation perspective, the results of the analysis indicate that each ethnic group behaves differently. Specifically, the concentration of these immigrants differed at both regional and neighbourhood levels.
