The new concept of bioremediation of anthropogenic water bodies and quarry wastewaters treatment by phytoextraction
and phytotransformation in the Arctic conditions is presented. This technology is based on transformating
the man-caused water reservoirs into nature-like marsh ecosystems. At the first stage, a new patented method for
advanced waste treatment using floating bioplato was developed and implemented. After implementing the bioplato,
the concentration of ammonium ions in water decreased by 53–90%, nitrate nitrogen reduced by 15–20%. At the
second stage, the floating bioplato technology was modified into the highly efficient purificating marsh ecosystem,
which allowed to cover the waterbody territory to the greatest possible extent. The technology is based on the creation
of phytomats enabling in the accelerated mode to form plant blocks of three different types. They are aimed
both at local grassing down, and at swamping deep and shallow areas of sediment ponds. In forming phytomats,
two soil substitutional substrates (thermovermiculite, wood sawdust) and regionally-optimized assortment of 24
plant species are used. The proposed technology does not require energy, chemicals and soil components which
are scarce in the region. The predominance of natural ecosystem processes in the formed phytocenoses allows to
achieve maximum efficiency, and the use of available materials contributes to minimizing the costs of creating and
maintaining the system. The introduction of this technology and formation of the artificial phytocenosis with the
area of about 30% of the man-caused reservoirs territory made it possible to increase the efficiency of wastewater
treating from mineral nitrogen compounds by 22%.
The paper presents the results of innovative design development for multicomponent adsorption filters with sliding
cartridges or with a metal-graphite electrode system. The proposed filters allow providing water purification by 98–99%
simultaneously from various polluting organic substances, including polycyclic aromatic hydrocarbons. The filtering media
of these filters include bentonite modified by various methods. To study the effectiveness of adsorption filters as a rapid
method, qualitative spot test analysis (sensu Feigl) was used. To control the content of polycyclic aromatic hydrocarbons
in aqueous media and to ensure effective sewage treatment of natural contaminated waters, a luminescent solid-substrate
method was applied. This method permits combining the preceding sorption concentration of substances on a cellulose
matrix, modified with a surfactant, and analyzing directly in the solid phase of the sorbent. Optimal characteristics of
luminescent control of ecotoxicant content before and after water purification were determined. Laboratory studies on
water treatment efficiency using multicomponent adsorption filter with retractable cartridges of a model solution including
a complex of polluting organic substances (pyrene, chrysene, benzpyrene, resorcinol) allowed identifying optimal
filtering media represented by activated silica gel; bentonite, modified with carbon nanotubes and glycerol after heat
treatment at 650 оC; bentonite after heat treatment at 650 оC; bentonite, modified with carbon nanotubes after heat treatment
at 550 оC. Laboratory studies of water purification efficiency by multicomponent adsorption filter with metallographic
electrode system of a model solution, including pyrene, chrysene, benzpyrene, resorcinol, m-aminophenol, o-toluidine,
permitted to identify the most efficient filtering media comprising of synthetic zeolite; bentonite modified with carbon
nanotubes and glycerol after heat treatment at 550 оC with a gradual temperature increase; organobentonite; bentonite
modified with carbon nanotubes and glycerol after heat treatment at 550 оC; activated silica gel; bentonite after heat treatment
at 800 оC. The proposed effective sorption water purification systems based on a multicomponent filtering media
with luminescent control of ecotoxicant content in resulting solution can be recommended for successful introduction at
industrial enterprises, producing wastewaters, as well as at water treatment plants.

The dynamics of the elements of fitness of experimental populations of Drosophila under conditions of chronic low-intensity exposure
I.N. Yuraneva, V.G. Zainullin
Section: Population ecology
One of the main issues of radiobiology is the study not only of the sensitivity of cellular structures and individual
systems of the body under chronic irradiation, but also the study of genetic variability of populations. Chronic exposure
increases mutations in the population and stabilizes the number of mutations after several generations. It is shown that
as a result of low-dose exposure to natural populations, the genetic load has been growing for many generations until
the level of mutation load stabilizes.
The study of the dynamics of genetic variability of populations, which is characterized by indicators of adaptation
of individuals (fertility, viability) to environmental conditions and mutation load (dominant lethal mutations) allows
not only to assess the sensitivity of populations to the effects of adverse factors, but also to determine the mechanisms
of maintaining homeosis populations in changing conditions. The effects of low-dose chronic radiation on experimental
populations of Drosophila derived from wild-type lines that differ in the content of mobile genetic elements are studied.
It is shown that chronic irradiation (0.25 mGy/h, Ra-226) for 30 generations leads to destabilization of the genome,
manifested in changes in the indicators of adaptability and mutability of populations, namely, in a significant increase
in the level of embryonic mortality, reducing the level of viability, increasing the frequency of dominant lethals, reducing
fertility in irradiated populations.

Red Book of vascular plants along oil pipelines in Yaroslavl Region
L.P. Kapelkina, T.E. Teplyakova
Section: Population ecology
Oil-pipe line exploiting is connected inevitably with an influence upon natural biotopes. The route of our investigation
of technogenic biotopes passed along 30 km of oil-pipeline protection zone. There were found 11 vascular plant species from
173 of Yaroslavl Region Red Book: Carex sylvatica Huds., Dactylorhiza baltica (Klinge) Orlova, Dactylorhiza fuchsii (Druce)
Soó, D. incarnata (L.) Soó, D. maculata (L.) Soó, Glyceria lithuanica (Gorski) Gorski, Listera ovata (L.) R.Br., Neottia
nidus-avis (L.) Rich., Ophioglossum vulgatum L., Veratrum lobelianum Bernh., Platanthera bifolia (L.) Rich, in addition
Dactylorhiza baltica also is the species of Russian Federation Red Book. The important information including status of Red
Book plant species, category of protection, biotopes and living state is given in the article together with the indispensable
protective measures fot its preservation and the necessity of periodical plant monitoring. Some Red Book plant populations
are scanty or even found in a single number. The most of them are corresponding with satisfactory living states. Species of
Dactylorhiza are more prevailing in pipeline protection zone than other Red Book plants. This phenomenon is connected
with auspicious conditions of lighting and moistening in meadow and marsh-meadow biotopes that are formed after felling
trees and shrubs. Within protection zone with Red Book plants felling is expedient in autumnal period after ripening and
seeds fall. During reconstruction of oil-pipeline transplantation of Red Book plants is higly recommended to the nearest
appropriate biotope not included in the area of reconstructive work, but optimally to the protected areas.

Red Book of vascular plants along oil pipelines in Yaroslavl Region
E.A. Snegin, A.S. Barkhatov
Section: Population ecology
On the basis of morphometric, phenetic and molecular genetic methods, the population structure of the Pelophylax
ridibundus inhabiting the urbanized environment of Belgorod and its environs (Russia) was studied. The obtained results
confirmed the previously stated assumptions, according to which under the conditions of anthropogenic load the
color morph “striata” dominates (the proportion of individuals on impact territories was 70 to 93%). In relatively pure
biotopes, the color morph “maculate” prevailed (58–67%). The morphometric characteristics revealed a significant differentiation
of populations, caused by heterogeneity in the urban environment. For most morphometric indices, ANOVA
showed significant differences between groups (p < 0.05), which is probably a consequence of the heterogeneity of the
urban environment, especially in terms of contamination and food supply. But the index of genetic differentiation (Fst)
at allozyme loci averaged 0.264, and the level of gene flow between populations (Nm) ranged from 0.107 to 32 individuals
per generation. This indicates an obvious panmixia among the populations of P. ridibundus in the study area. Occasionally
nonspecific allozyme loci were noted, indicating the hybrid origin of the individuals (hybrids between P. ridibundus and
P. lessonae). The high of genetic diversity indices (He = 0.394±0.061, I = 0.629±0.100) and the low inbreeding values in
populations (IF = -0.112±0.075) indicate an increased viability of the amphibian groups studied in the study area, which
is a consequence of the adaptations of populations of P. ridibundus to inhabitation in urban conditions.

Content of heavy metals in urban surface water bodies
E.G. Riabova
Section: Population ecology
Today urban territories became the main habitat for people, but together with the rising level of economic and social
advantages, they also have some ecological problems. And one of them is the pollution of urban water bodies with different
toxicants, such as heavy metals. In this study, the analysis of surface water bodies carried out to containing of some heavy
metals, such as: Pb, Fe, Mn, Sr, Zn, Cd and Cu, as well as comparison of obtained results with the results of previous research
in 2006. During the research it was found that the main heavy metal contaminating town water bodies is cadmium (Cd),
which average concentration is thirtyfold higher then allowed statutory level of contaminants for water bodies to amenity
needs. Maximal concentration of Cd is 37 MPCan (maximum permissible concentration in water bodies to amenity needs)
was evidenced in the pond inside the industrial area. The other heavy metals found in water bodies and benthic sediments
in concentrations 2–5 MPCan were Pb, Fe and Mn. The results were compared with the previous research data in 2006, and
it should be noticed, that during the eleven years concentrations of Pb and Mn lowered a bit, but they are still higher than
MPCan. At the same time, concentrations of Fe and Cd have slightly increased. In regards to heavy metals’ concentrations
in sediments, their dynamics changed a little. Basing to the obtained data, the specific combinatorial water pollution index
(SCWPI) was calculated. This index characterizes water pollution rate, and for water bodies in Dzerzhinsky town SCWPI
was 11 points, which indicates that surface waters in the town could be classified as “strongly polluted waters”.

Content of toxic elements in water and macroalgae of the Argun River (Russia) basin water courses
A.P. Kuklin, G.Ts. Tsybekmitova
Section: Chemistry of natural environments and objects
The Argun River, as a transboundary stream flow between Russia and China, is an indicator of the existing pollution
in its catchment area. The estimated content of 12 toxic elements in water and in macro-algae of eight tributaries
of the Russian part of the basin of the Argun and in the Argun (seven sections), showed the greatest pollution of
the waters of the river Srednyaya Borzya. The content of toxic elements in the water of the Srednyaya Borzya, below
the gold washing areas, is (mkg/dm3): Mn – 171, Fe – 4994, Cu – 66, Zn – 102, As – 7, Mo – 3, Hg – 0.02, Pb – 13,
which is several times higher than maximum permissible concentration of these metals. The high content of Fe and
Mn among heavy metals in the rivers of the basin is connected with the specific features of the rocks in the study area.
The marked toxic elements can be transported with solid runoff over long distances, settle in bottom sediments, thereby
subjecting stream flows to secondary pollution. For most of the stream flows, it was exceeded the number of toxic
elements in Cladophora fracta from the basin of the river Argun, relative to the background concentrations, typical
for the water bodies of Zabaikalsky Krai. The greatest differences were recorded in samples of algae from the reserve
reservoir of Krasnokamensk (Zn, As, Ni), in the river Srednyaya Borzya (Mo, Cd, Pb), in the river Kalga (Mn, Co,
Mo). In the reservoir of Krasnokamensk in wintertime, water is pumped from the river Argun, which has the highest
mineralization in this period. The obtained results can be used in monitoring of water pollution by toxic elements and
for making managerial decisions.

Environmental aspects of sulfate turpentine refining (review)
Е.S. Izmest`ev, S.А. Rubtsova, А.V. Kutchin
Section: Theoretical problems of ecology
The burning of sulfate turpentine, formed as a by-product of pulp and paper mills during the kraft pulping process,
causes irreparable environmental damage, as it contains a large number of toxic sulfur-containing compounds generating
sulfur dioxide when being combusted. It is for this reason that the search for methods of removing sulfur compounds
from the sulfate turpentine, which can make the purified product a valuable source of terpene compounds suitable for
industrial processing, is being actively pursued. The problem of complex refinement and rational utilization of turpentine
is mainly to establish a waste-free use of feedstock for obtaining useful products. However, the lack of selectivity in the
conversion of terpenes which are the main components of turpentine, and the complexity of their separation hinder the
development of effective methods for refining turpentine. In this regard, the refined turpentine is used mainly as a solvent
for varnishes and paints. At the same time, it is a valuable biofuel, capable, with proper approach, of partially replacing
fuels produced from mineral oil. Terpenes from turpentine and their derivatives are widely used in the organic synthesis
of biologically active substances, antioxidants, pesticides, herbicides, in the perfume industry for producing fragrances
(linalool, geraniol, nerol, citronellol), and also for obtaining compounds with a pronounced insecticidal , repellent,
antimicrobial, anti-inflammatory, hypoglycemic and other types of biological activity. Sulfur-containing compounds
can achieve widespread use in organic synthesis to manufacture solvents, ion-exchange resins, dyes, in the synthesis of
detergents and reagents for the chemical industry (sulfochlorides, thiosulfonates, sulfoxides).

Multivariate statistical analysis of ecological communities (review)
V.K. Shitikov, Т.D. Zinchenko
Section: Theoretical problems of ecology
The modern approach to the study of communities’ ecology involves the integration and joint processing of large
arrays of observations. This usually involves a variety of indicators (population, phenotypic, genetic, environmental,
chemical, landscape and geographical) which are characterized by significant temporal and spatial variability. The purpose
of the analysis is to identify significant statistical relationships of the taxonomic structure with the characteristics
of biotopes and environmental factors. It is based on multivariate methods that allow optimal projection of data with a
large number of variables into low-dimensional spaces.
The article focuses on the evolution of algorithms for multivariate analysis, starting with the classic unconstrained
ordination based on principal components (PCA) up to modern integrated symmetric methods used in omics technologies.
A class of algorithms, such as metric (PCoA) and non-metric (NMDS) multidimensional scaling, based on the calculation of distance matrices, is distinguished and the advantages and disadvantages of their use are considered. The dependence
of the results of redundancy analysis (RDA) and canonical correspondence analysis (ССA) on the distribution law of the
empirical data is discussed and recommendations for their preliminary transformation are given.
It is shown the role of such symmetric methods as the two-block algorithm of partial least squares (2B-PLS) and
the co-inertia analysis (CIA), which allow to establish by decomposition on axes of multidimensional covariations what
species from different complexes of observations are most associated among themselves. Procrustean analysis (PCIA)
can be widely used to identify changes in the species composition of the study region before and after some event (e.g.,
anthropogenic impact). Generalized Procrustean algorithms and canonical analysis (GPA, RGCCA, DIABLO) allow you
to work with a large number of tables and explore the dynamics of community structure for several sequential periods of
time or to form a consensus configuration by the best way.
References to numerous examples of the use of ordination methods in domestic and foreign literature are given. The
main prospects and directions of development of multidimensional methods in relation to the ecology of communities
are shown.
