Planktonic Heterotrophic Flagellates and Bacteria in an Oil-Polluted Taiga River

D. B. Kosolapov, N. G. Kosolapova
Pages: 3–10

Abstract >>
Patterns of distribution and community structure of heterotrophic flagellates and bacterioplankton were investigated in the Vatinsky Yogan river (the Tyumen region). Low microbial abundance was recorded in the river. 38 species of heterotrophic flagellates from nine taxons and a group of uncertain taxonomic position were found in the river. The majority of them belonged to the consumers of bacteria and detritus. A positive correlation between the oil concentrations in water and in bottom sediments, on the one hand, and the abundance and biodiversity of heterotrophic flagellates, on the other hand, was established.

Phenetic Diversity of the East-Siberian Grayling Thymallus

S. P. Pustovoit
Pages: 71–75

Abstract >>
Changes in the phenetic diversity of the population of East-Siberian grayling Thymallus arcticus pallasii Valenciennes, 1848 from the Buyunda river (the upper Kolyma) depending on the sex and age of individuals are analyzed. Among 16 phenes of the coloring of grayling dorsal fin in Eurasia four ones were detected on the dorsal fin of the East-Siberian subspecies. Fish of advanced age have a larger number of webs with the long-strip phene in comparison with younger fish, mainly webs without patterns or with patterns in the form of spots and short strips are present. Statistically significant differences between female and male individuals in the frequencies of the two phenes of four were detected. Variability of patterns in connection with fish growth should be taken into account when describing the habitus of grayling.

Interpopulation Changeability of Pike Esox lucius (L.) in Water Bodies of the Middle and South Ural

S. P. Silivrov, A. V. Gilev
Pages: 77–87

Abstract >>
The data on the interpopulation changeability and differentiation of pike populations in different types of water bodies on Middle and South Ural are presented. The investigated pike populations are significantly different from each other both in the entire complex of morphological traits, and separately in the complexes of plastic and account traits. The main component of distinctions between populations is a complex of plastic traits. In the population distinction over the entire set of features, the biotope conditions had a larger weight than the affiliation of a water body to a definite basin or its geographic position.

Peculiarities of Bird Urbanization

B. D. Kuranov
Pages: 123–132

Abstract >>
A city is like an island among the natural landscape. Therefore the principles of island ecology are suitable for a city. This approach may be used also to consider a city within its boundaries: the number of green open spaces, aquatories, their area, degree of fragmentation and distance from the perimeter of the urban zone. Natural analogues of urban bird communities in relation to diversity and domination may be the communities at an early stage of succession, under extremal conditions or often exposed to disturbances. Obviously adaptation of birds to urban habitats occurs as a result of pre-adaptation and various modifications. In some cases urban bird populations survive changes of reproductive biology and behavior. However, the observed changes are not universal for different species.

Dynamics of the Number of Rodents: Possible Ways to Solve the Problem

P. A. Panteleyev
Pages: 195–203

Abstract >>
The problem of perennial dynamics of the number of rodents is under investigation for more than a century. Its stalemate state is proposed to be accepted. In our opinion, the crisis originates from the attempts of the majority of researchers to reveal the facts of mortality leading to the failure of a population instead of revealing augmentation of population as a result of reproduction. The phenomenology of the dependence of the cyclic phase on the intensity of population reproduction is concealed. It is proposed to consider the problem of the population dynamics as two separate problems: the dynamics of
