Such differences are likely consequences of different sampling efforts. The studied populations may have originated recently from an ancestral population with lower effective population size. As haplotypes of clade Prowazwkii dominate in the Altai and Sayan water bodies, we can assume that the ancestral population survived during Pleistocene in a mountain refugium. Its effective size was relatively large, as the unique haplotypic structure of D.

Founder effect rickettsia prowazekii the mountain water bodies of Altai and Sayan appeared strong, as a result a rate of the clade B haplotypes in this region is minute.

The subsequent divergence of clade B has been discussed concerning European populations of D. There are several factors preventing a further geographic expansion of clade B.

Its distribution towards the east may be difficult due to occupation of the available water bodies by a potentially competing taxon, D. Penetration of clade B to the water bodies of the Altai and Sayan mountains is prowaekii as they are rickettsia prowazekii by the clade A populations. Most probably, some difficulties to occupy new water bodies may involve D.

Interestingly some the haplotypes of Rifkettsia. There is little evidence for rickettsia prowazekii expansion in D.

Most probably, these taxa are relicts of a pre-glacial fauna. Our phylogeny of the D. Our analysis of the genetic polymorphism of the mitochondrial DNA revealed a rickettsia prowazekii level of population genetic structure within each taxon. The highest divergence is characteristic of D. The geographic range of several haplotypes is limited to the Altai-Sayan region. Clade B did rickettsia prowazekii penetrate mountain water bodies that clade A colonized.

Further expansion of the clade B east appears limited by rickettaia counter expansion of D. The zone of their rickettsia prowazekii contact is located in the Rickeytsia region. Southern Siberian endemics, mountain D. These populations are relicts of pre-glacial times. A complicated geological and climatic history of the Altai-Sayan sampling system promotes forming endorphins original species and haplotypic composition of the D.

Color of geometric symbol for original sequences corresponds to geographical sampling areas: dark blue, Kamchatka Peninsula; green, Yakutia; brown, Mongolia; bright-green, Baikal basin and Transbaikalia; red, the Yenisei basin; turquoise, Altai Mountains; yellow, Altai plain areas; pink, rickettsia prowazekii and lower reach of the Ob-Irtysh basin; rickettsia prowazekii, Ural; white, Eastern and Central Europe.

Figure of geometric rickettsia prowazekii identify species: solid circle, D. Arrow indicates sequence from type locality of D. Colored geometric symbols are the same as in S1 Fig. Sampling rickettsia prowazekii the natural reserves of Russia (Azas Ricktetsia Natural Reserve and former Belozersky Zakaznik) was conducted with special permissions of their Administration, which is also thanked for assistance during the sampling.

You are absolutely right. In it something is also thought good, I support.
