The absence of panmixia at all hierarchical levels of the European beaver communities down to individual families implies a complex organization of the population-genetic structures of the species, in particular, a large intergroup component of gene diversity in the populations. Testing this assumption by analysis of 39 allozyme loci in the communities of reintroduced beaver from the Vyatka river basin (Kirov oblast) has shown that only the beaver colonies exhibit high intergroup gene diversity… 


Abstract The Eurasian beaver, Castor fiber L., suffered extreme demographic reduction through overhunting until the end of the 19th century. However, active protection measures have led to a powerful

Population genetic structure in natural and reintroduced beaver (Castor fiber) populations in Central Europe

There was an overall high genetic similarity in the species C. fiber, and no evidence was found for a clear subspecific structure in the populations studied, and the reintroduced beaver populations of different origins showed a similar low genetic heterogeneity.

Mitochondrial phylogeography of the Eurasian beaver Castor fiber L.

The low level of sequence divergence of the entire cytochrome b gene among six individuals representing six subspecies suggests differentiation during the last glacial period and existence of multiple glacial refugia.

Variation of allele composition and protein locus expression in the course of genetic differentiation of taxa of different ranks in the mammals

Comparison with data on other groups of vertebrates shows that the ratios between these groups of loci reflect the specificity of differentiation processes at the intraspecific level and the levels of species and taxa of higher ranks in all classes of animal analyzed.

Ecological impact of beavers Castor fiber and Castor canadensis and their ability to modify ecosystems

It is suggested that beavers can create important management opportunities in the Holarctic, and this review will help land man- agers determine the likely outcome of beaver activity.

Dynamics of food resources for beavers in settlements colonized and abandoned several times

It has been shown that tree stands surrounding the settlements differ in composition and degree of damage but are similar in that they contain no forage for beavers: aspen is absent, and birch trees are large and require great efforts to cut them down and utilize.

Intrapopulation Polymorphism of the Pine Marten (Martes martes, Carnivora, Mustelidae) from Tver Oblast

Low levels of phenetic, morphometric, and morphological diversity as well as a low level of sexual dimorphism indicate that the pine marten occupies a specific and relatively narrow ecological niche and is involved in weak competition with smaller mustelid species.

Duplication and population dynamics shape historic patterns of selection and genetic variation at the major histocompatibility complex in rodents

The need to consider demographic history and genetic structure alongside patterns of natural selection to understand resulting patterns of genetic variation at the MHC is highlighted.

Distribution and biology of the ectoparasitic beaver beetle Platypsyllus castoris Ritsema in North America (Coleoptera: Leiodidae: Platypsyllinae)

The distribution and biology of the beaver beetle, Platypsyllus castoris Ritsema, are summarized for North America and it is asked if the Nearctic and Palearctic beetle populations are really the same species.

Using theoretical developments in the field of anthropology of nature, the problem of perception of social bonds in beavers and other animals by residents of the Volga region was considered. It was



Genetic Divergence and Similarity of Introduced Populations of European Beaver (Castor fiber L., 1758) from Kirov and Novosibirsk Oblasts of Russia

Potential factors were analyzed that affected the formation of gene pools of two introduced beaver populations founded in the 1940s–1950s by releasing beavers from Voronezh oblast and Belarus into rivers of the Kirov and Novosibirsk oblasts to indicate the existence of interpopulation heterogeneity at the level of local populations of fourth- and fifth-order rivers.

[Allozyme variability of the European bean Castor fiber 1758 (Castoridae, Rodentia) from the Voronezh State Nature Reserve].

A comparison between allozyme spectra of samples of European and Canadian beavers revealed many coinciding polymorphic loci, on the one hand, and pronounced genetic divergence of these species, in the other.

Most of the genetic variants known in the house mouse were discovered and studied in mice bred in the laboratory, under highly protective conditions and so are of little value in the investigations of genetic aspects of natural populations.

Major histocompatibility complex monomorphism and low levels of DNA fingerprinting variability in a reintroduced and rapidly expanding population of beavers.

It is shown here that this viable population of beavers in Sweden possesses extremely low levels of genetic variability at DNA fingerprinting loci and monomorphism at major histocompatibility complex (MHC) class I and class II loci, indicating that the European beaver is exceptional in its low level of MHC variability.

Genetic Diversity in Nature

Genetic diversity is the basis of evolutionary change. Ironically, however, the recently discovered abundant genetic diversity in natural populations through allozymic variation did not highlight its

Isolation by Distance.

Statistics of statistical differences among local populations provide a possible basis for intergroup selection of genetic systems, a process that provides a more effective mechanism for adaptive advance of the species as a whole than does the mass selection which is all that can occur under panmixia.

Two Programs to Estimate Significance of χ2 Values Using Pseudo-Probability Tests

Two programs, CHIRXC and CHIHW, which estimate the significance of x statistics using pseudo-probability tests, permit analysis of sparse table data without pooling rare categories and prevents loss of information.
