BIOCENOSES OF SMALL RIVERS IN THE KRASNODAR KRAI

Posted in 2020, BIOLOGY, Issue № 10(100) October 2020, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

The author provides a brief description of studied small rivers of the Krasnodar Krai and gives their fishery categories. The description and analysis of the qualitative and quantitative characteristics of zoocenoses of small rivers in the Krasnodar Territory are given for the first time, based on the results of the study of the main groups of aquatic organisms (phytoplankton, zooplankton, zoobenthos, fish). The author also provides information on the average annual biomasses of phytoplankton, zooplankton, and zoobenthos. The data on the ichthyofauna species composition in small rivers, their potential fish productivity, and the productivity of spawning grounds are presented as well. The study of ichthyofauna is of both scientific interest and of practical value in the study and conservation of biological diversity under conditions of powerful anthropogenic impact.

APPLICATION OF GENERAL ANTIOXIDANT INDEX FOR INTEGRAL ASSESSMENT OF ANTIOXIDANT STATUS OF RAT BRAIN TISSUES ASSOCIATED WITH MECHANICAL EYE INJURY

Posted in 2020, BIOLOGY, Issue № 10(100) October 2020, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

The blood-ocular barrier protects the tissues of the nervous system from adverse factors, but it can interfere with the action of natural antioxidants, thereby contributing to the accumulation of neurotoxins and provoking the development of cyclic pathological processes. However, large molecules, including medicines associated with the inflammatory process, can penetrate the eyeball. Besides, the permeability of the blood-ocular barrier increases with various injuries (mechanical, physical, chemical, biological, and biochemical). Currently, the homeostatic balance restoring mechanism of the body under oxidative stress has not been studied enough. Therefore, the research of the pathogenesis mechanism and therapy of inflammatory processes in the organs of vision is of great importance. The goal of this work is to study the dynamics of the total antioxidant index for the integral assessment of the antioxidant status of rat brain tissues under oxidative stress caused by mechanical action on the blood-ophthalmic barrier. Materials and Methods: The work was carried out on outbred white sexually mature healthy male rats of six months, weighing 220-240 g, 150 animals were tested. They were divided into five groups with thirty rats in each group— the 1st group of rats – intact animals. The 2nd, 3rd, 4th, and 5th were experimental ones, where all animals got penetrating wounds in both eyes. Animals in the 2nd group did not get any mechanical eye injury therapy. The rats of the 3rd group got standard therapy for eye injury. The animals of the 4th group got standard therapy with the addition of intraperitoneal quercetin injections, and those of the 5th group got only quercetin injections. The activity of catalase, cumulative dose, GP and GR, as well as the concentrations of MDA and DC before the start of the experiment and on days No. 1, 3, 5, 7, and 14 of the experiment, were determined in the rat brain tissues. Then the total antioxidant index was calculated for each day and each group of animals. The resulting digital material was subjected to statistical processing by nonparametric statistical analysis. Conclusions: the antioxidant status of rat brain tissues under oxidative stress caused by mechanical action on the blood-ocular barrier can be most effectively stabilized by standard therapy of mechanical eye injury with the addition of quercetin in the form of injections.

ATTEMPTING TO USE BIOINDICATELLY AND BIOCHEMICAL METHODS FOREVALUATING THE QUALITY OF WATERSUR FACE ARTIFICIAL WATER

Posted in 2014, BIOLOGY, Issue November 2014, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

Investigated the biological diversity and the sustainability of biocenosis permanent artificial surface water flowin the territory of Orekhovo-Zuevsky district Moscow region. Set relative homogeneity of water to anthropogenic pressure. Condition of the water course is estimated at 3 cross-sectionsat the level of 5 class quality. It is noted that the studied biotopes unfavorable habitat for aquatic organisms. For comparison, the data purity water Klyazma river at the confluence of the water course in her (target 4), rated at 3 class quality.

ASSESSING THE ANTIBIOTIC RESISTANCE OF VARIOUS GROUPS IN WATER ENVIRONMENT THROUGH BIOTESTING

Posted in 2020, BIOLOGY, Issue № 09(99) September 2020, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

The article presents experimental data demonstrating the possibility of biotesting method application using the cuttings and seedlings of land plants as test organisms for the indirect assessment of the antibiotics oxytetracycline, tylosin and ceftriaxone resistance in the water environment. In the experiments, we used tap water settled for ten days and chlorinated. For test organisms, we selected cuttings of Canadian waterweed, seeds of red radish having a white tip and of the mung bean (maash), and as the test parameters, we chose the length of the root and the scions and the weight of the cuttings of Canadian waterweed. Antibiotics solution for biotesting were first stored in dark glass bottles for 0.2, 14, 28, 42 days at room temperature, then used for the experiments.

RESULTS OF THE RESEARCH ON THE DECORATIVE FEATURES OF SOME DAFFODIL VARIETIES DURING THEIR INTRODUCTION IN THE SOUTHERN URALS

Posted in 2020, BIOLOGY, Issue № 09(99) September 2020, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

The article presents the results of the initial introduction study of nine new varieties of the genus Narcissus L. (‘Apricot Whirl’, ‘Candy Princess’, ‘Green Eyes’, ‘Mon Cheri’, ‘Peach Cobbler’, ‘Slim Whitman’, ‘Sunlover’, ‘Sunny Girlfriend’, ‘Sunny Side Up’) based on the South-Ural Botanical Garden-Institute of the Ufa Federal Research Centre of the Russian Academy of Sciences. According to the Cultivated Plant Code, the introduced plants were divided into four groups: Large-cupped, Small-cupped, Double, and Cutleaf Daffodils (Split-crown). It was revealed that during the two years of study, all cultivated varieties got to the flowering period. The authors studied the main biomorphological parameters of the introduced plants (plant height, leaf length and width, flower diameter, length and width of the cup and the perianth lobes). It was determined that most varieties are characterized by two-tone colour and average flower size. Phenological observations were made. It was revealed that spring regrowth in all the studied varieties is observed after snow melting in the second decade of April. According to the flowering time, the cultivated varieties were divided into the early (flowering in the third decade of April) and the early-middle (flowering in the first decade of May). The duration of the flowering phase lasted on average from 6 to 12 days. The decorative qualities of the studied varieties were researched. When garded on a 100-point scale, five cultivated varieties received over 90 points (‘Mon Cheri’, ‘Sunlover’, ‘Candy Princess’, ‘Apricot Whirl’, ‘Sunny Side Up’). They have large and decorative flowers in shape, with a clear, bright colour of the perianth and the cup, high and robust flower-bearing spikes, long-lasting and abundant flowering, and a pleasant aroma. These breeds are the most promising for inclusion in the regional range of the cultivated plants recommended to use for the green construction in the Republic of Bashkortostan.

EFFECT OF RECULTIVATION ON METAL ACCUMULATION IN ORCHID PLATANTHERA BIFOLIA UNDER ASH DUMP CONDITIONS

Posted in 2020, BIOLOGY, Issue № 09(99) September 2020, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

The results of studying the metal accumulation in the orchid Platanthera bifolia (L.) Rich. in the ash dump (Verkhnetagilskaya Thermal Power Station, Middle Urals) are presented. A comparative analysis of the metal content in the ash substrate and plants from the non-recultivated and recultivated sites of the ash dump was carried out. It is shown that under the influence of recultivation measures the total content of magnesium, calcium, iron, zinc, copper and nickel in the substrate was increased. At the same time, the proportion of mobile forms and the metal accumulation by plants in most cases were decreased. It was concluded that partial recultivation of the ash dump by applying clay soil can help to reduce the risks from excess metal input into plants.
