Аннотация: The distribution of different ecological groups of lichens (acidophytes, 'nitrophytes', indifferent species) was compared on 1-24 year-old twigs of Abies sibirica sampled in the 'pristine' West Sayan and the polluted East Sayan Mountains (Krasnoyarsk District, South Siberia, Russia) to test their value as indicators of current pollution effects. Bark pH of twigs and bark chemistry (N, S, Ca, Mg, Al, Fe) were measured, and a preliminary estimate of emissions in the Krasnoyarsk District from livestock animal populations was calculated. In both regions, an unusually high twig bark pH and an abnormal species composition for A. sibirica canopy were found (e.g. Physcia aipolia, P. dubia, P. tenella, Phaeophyscia sp., Melanelia exasperatula and Candelariella vitellina), with P. tenella (East Sayan) and M. exasperatula (West Sayan) as dominants. The results confirm that the distribution of lichen species on Abies sibirica twigs is a valuable indicator of current changes in atmospheric conditions.

Аннотация: Efficient syntheses of (ZE)-5,7-dodecadienol, a pheromone component of the Siberian moth, Dendrolimus superans sibiricus, and (E,Z)-10,12-hexadecadienol, a pheromone component of various Lepidoptera pheromones, were accomplished by cis reduction of the corresponding enynols with activated zinc. The most energetic reagent was zinc galvanized with copper and silver (Zn/Cu/Ag) that achieved rapid and high-yield reduction in methanol-water. The stereoselectivity of semihydrogenation was greater than or equal to98%. A process whereby zinc dust was continuously activated throughout the reduction with an acid was also satisfactory (95-98% cis). Field evaluation of the 1:1 mixture of (Z,E)-5,7-dodecadienol and (Z,E)-5,7-dodecadienal with the Siberian moth in Russia showed that the rubber septa pretreated with compound and stored at -80 degreesC were as effective as freshly treated septa. Moth responses to septa aged in open air indicated that lure effectiveness declined significantly after 2 weeks of aging. Thus, if rubber septa are used as pheromone dispensers in Siberian moth traps monitoring, they should be replaced biweekly with fresh septa for optimal trap effectiveness.

Аннотация: 1 The native range of the Siberian moth extends from the Pacific Ocean (Russian Far East, Japan and Northern Korea) across Siberia, Northern China and Mongolia to the Ural Mountains. At the beginning of the 21st Century, this species was documented west of the Ural Mountains in the Republic of Mari El, indicating range extension toward the west. 2 The Siberian moth has recently been suggested for regulation as a quarantine pest for European and Mediterranean Plant Protection Organization member countries. However, no specific report on European host plants for this pest has been published so far. 3 In the present study, larval host plant choice and performance was tested for the first time on coniferous tree species that are widely distributed and of commercial value in Europe. 4 Based on dual-choice tests on neonates and mortality, developmental duration and relative growth rates of the first- to sixth-instar larvae, we found European larch Larix decidua to be the most suitable host for the moth larvae, whereas European black pine Pinus nigra and Scots pine Pinus sylvestris were the poorest hosts. The remaining conifer species tested, European silver fir Abies alba, Nordmann fir Abies nordmanniana, and Norway spruce Picea abies, were intermediate host plants. Douglas-fir Pseudotsuga menziesii, originating from North America, was chosen by the larvae to the same extend as European larch, and was also highly suitable for larval development. 5 If the moth is introduced to European countries, it will become damaging in stands of European larch and Douglas-fir, mixed stands of fir and spruce; however, it will be less damaging in forests dominated by two-needle pines. 6 We predict that Dendrolimus superans sibiricus will be able to survive and develop on the main European coniferous tree species, including non-native coniferous tree species, resulting in severe damage to large areas of forests.

Аннотация: The following major phenolics with non-flavonoid structure were identified from leaves of Betula pubescens (white birch) and Betula pendula (silver birch): 1-O-galloyl-beta-d-(2-O-acetyl)-glucopyranose, 1-(4 ''-hydroxyphenyl)-3'-oxopropyl-beta-d-glucopyranose, gallic, chlorogenic, neo-chlorogenic, cis- and trans-forms of 3- and 5-p-coumaroylquinic acids. Chromatographic (analytical and preparative HPLC), chemical (hydrolysis) and spectroscopic (UV,H-1 and C-13 NMR, MS) techniques were applied for separation, isolation, purification and identification of these phenolics. Moreover, 33 low-molecular-mass phenolics were detected and quantitated and their occurrence was compared in leaves of white and silver birches.

Аннотация: The significant growth in applications of silver nanoparticles across -various branches of industry as well as in consumer products has caused concerns that nanosilver may have a toxic effect on the environment and human health and may have implications for eco-terorism. This paper presents research on antimicrobial effects of silver nanoparticles. We studied the cytotoxicity of silver nanoparticles via an MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium-bromid) assay that measures cell activity through the mitochondrial cleavage of a molecule that exhibits a change of colour that can be measured spectrophotometrically. NIH-3T3 (Swiss mouse embryo), HEP-G2 (human hepatocellular carcinoma), A-549 (human lung carcinoma), PC-12 (rat adrenal pheochromocytoma), and Colo-320 (human colon adenocarcinoma) cells were chosen in order to study different possible absorption paths of nanoparticles into the organism and various areas of particle accumulation in the body. The obtained MTT test results have shown that silver nanoparticles with concentrations of ∼1-10 ppm entering the body from air or liquid suspensions can present a potential risk to human health. © Springer Science+Business Media B.V. 2011.

Аннотация: Antimicrobial and antifungal properties of silver nanoparticles, silver ions, acrylate paint and cotton fabric impregnated with Ag nanoparticles were assessed against Escherichia coli (Gram-negative bacterium); Staphylococcus aureus and Bacillus subtilis (Gram-positive bacteria); Aspergillus niger, Aureobasidium pullulans and Penicillium phoeniceum (cosmopolitan saprotrophic fungi). The silver ions used in the bacterial susceptibility tests were released from pure silver electrodes using a 12 V battery-operated direct current generator. The water-based silver colloidal solution was obtained by electroreduction of silver ions in water. Nanosilver was less effective against E. coli, S. aureus, B. subtilis and P. phoeniceum compared to silver ions. However silver nanoparticles have prolonged bactericidal effect as a result of continuous release of Ag ions in sufficient concentration and thus nanoparticles can be more suitable in some bactericidal applications. The synthesized silver nanoparticles added to water paints or cotton fabrics have demonstrated a pronounced antibacterial and antifungal effect. В© 2011 Springer Science+Business Media B.V.

Аннотация: The minimum inhibitory concentrations (MICs) assays conducted for E. coli, S. aureus, B. subtilis and P. phoeniceum have shown that the antimicrobial activity of silver ions was superior to that of silver nanoparticles. As silver nanoparticles can be more suitable in some bactericidal applications than silver ions, the efficacy of nanosilver as an antimicrobial agent against a range of microbes on the surface of water paints and cotton fabrics has been studied. The cytotoxicity of silver nanoparticles has been studied using NIH-3T3, HEP-G2, A-549, PC-12, and Colo-320 cells via the MTT ((3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium-bromid) test. The MTT test results obtained have shown that silver nanoparticles in concentrations of ~1-10 ppm entering the body from air or liquid suspensions can present a potential risk to human health. However, silver nanoparticles as a commercially viable addition to be used in paint and textile industry are unlikely to present a direct health risk. © 2010 Nova Science Publishers, Inc.

Аннотация: The response of vegetation to climate change is of special interest in regions where rapid warming is coupled with moisture deficit. This raises the question of the limits in plants' acclimation ability and the consequent shifts of the vegetation cover. Radial growth dynamics and climatic response were studied in Scots pine (Pinus sylvestris L.), Siberian larch (Larix sibirica Ledeb.), and silver birch (Betula pendula Roth.) in the forest-steppe, and for Siberian elm (Ulmus pumila L.) in the steppe of South Siberia, as indicators of vegetation state and dynamics. Climate-growth relationships were analyzed by the following two approaches: (1) correlations between tree-ring width chronologies and short-term moving climatic series, and (2) optimization of the parameters of the Vaganov-Shashkin tree growth simulation model to assess the ecophysiological characteristics of species. Regional warming was accompanied by a slower increase of the average moisture deficit, but not in the severity of droughts. In the forest-steppe, the trees demonstrated stable growth and responded to the May-July climate. In the steppe, elm was limited by moisture deficit in May-beginning of June, during the peak water deficit. The forest-steppe stands were apparently acclimated successfully to the current climatic trends. It seems that elm was able to counter the water deficit, likely through its capacity to regulate transpiration by the stomatal morphology and xylem structure, using most of the stem as a water reservoir; earlier onset; and high growth rate, and these physiological traits may provide advantages to this species, leading to its expansion in steppes. © 2019 by the authors.

Аннотация: In moisture-limited regions in which droughts leave a significant “footprint”, monitoring of quantitative climatic parameters and of forest adaptation and acclimation to these parameters is of utmost importance due to the ambiguity of spatial patterns in reaction of tree growth to drought and the variety of drought resistance strategies exhibited by trees at the genetic, morphological and physiological levels. This is a case study of the radial growth of Siberian larch (Larix sibirica Ledeb.) along the forest-steppe transect in the foothills of the Bateni Ridge (Kuznetsk Alatau, Southern Siberia, Russia) and of its climatic response and stability under the influence of droughts and contributing factors. In this region, a permanent mild moisture deficit is gradually increasing due to warming of the vegetative season by 0.14–0.19 °C per decade; droughts occurred in 1951, 1963–65, 1974–76, and 1999. The forests in the region are represented by pure larch stands in the west and mixed stands of larch with Scots pine and silver birch in the eastern portion of the ridge. The forest-steppe ecotone comprises a significant part of the ridge area, mainly on the southern and southeastern slopes. At 5 sampling sites, dependence of larch growth on precipitation (P) and standardized precipitation-evapotranspiration index (SPEI) during April–July of the current year and June–September of the previous year and on maximum temperature (Tmax) during May–July of the current year and July–September of the previous year was observed. We propose the use of a linear regression model based on the SPEI of these seasons as an individualized indicator of climate aridity, which is biologically significant for larch in the study area. An analysis of pointer years showed that precipitation in November (formation of snow cover) also contributes to larch growth. The larch in the study area tolerates moisture deficit, rebounding after the end of stress exposure. The spatiotemporal patterns of the stability indices revealed that despite the decrease in growth resistance and resilience with drought severity, these characteristics are higher at more arid sites due to trees’ acclimation to permanent climate aridity. The findings contribute to a better understanding of the capability of larch to further acclimatize and provide a basis for planning measures for conservation and/or restoration of the region's forests under climate warming; however, to clarify the contributions of factors at the individual and local scales, further investigation of the stability of larch growth at the level of individual trees may be required. © 2019 Elsevier B.V.

Аннотация: The growth of bacteria and fungi on a nanofiltration (NF) membrane is known to reduce its permeability and lifetime and increase overall energy use. Over the last decade, application of silver nanoparticles (AgNPs) has shown to present a strong potential in preventing biofouling of NF membrane processes. The paper deals with a novel facile method developed to in situ incorporate nanosilver stabilized with the polyhexamethylene biguanide hydrochloride (PHMB) onto the commercial NF membrane surface. The scanning electron microscopy (SEM) investigations confirmed a uniform distribution of AgNPs on the surface of NF membrane although AgNPs tend to agglomerate into nano-sized colloidal clusters. Our results showed that AgNPs had little impact on the performance of the NF membrane, including salt rejection and water permeation properties. To evaluate the antibacterial properties of nanocomposite membranes, a "time-kill" analysis, a microbiological technique for measuring the change in a population of microorganisms under the impact of a specific sample, has been used against representatives of Gram-positive and Gram-negative bacteria. Inductively coupled mass spectrometry (ICP-MS) was used to study kinetics of Ag release from modified NF membrane. Leaching rates of Ag were low that will possibly result in long-established antimicrobial and antifungal properties. The present research offers a potential for its further use as a new type of modified NF membrane mitigating biofouling.

Аннотация: Cation exchange resins are widely used for water softening and demineralization all over the world. Deposition, metabolism, and growth of bacteria and fungi on the resin beads cause capacity and performance losses, especially during repeated use in cyclic and long-term operations. Over the last decades, modification of different materials by silver nanoparticles (AgNPs) has demonstrated to present significant opportunities in mitigating biofouling problems. The paper deals with a novel facile technique of introducing silver colloids (AgC) into cation exchange resin, providing the formation of silver micro-and nano-inclusions on the cation resin beads. The scanning electron microscope (SEM) measurements have confirmed a spherical shape and uniform distribution of AgC (50 - 1000 nm) on the surface of the resin. To evaluate the antibacterial and fungicidal properties of AgC on the cation resin beads, we have used Aureobasidium sp., Penicillium sp., and Staphylococcus aureus cultures. AgC coating has proved to efficiently prevent bacteria/biofilm growth on the cation resin beads and thereby significantly increase the service life of the cation exchange resin, especially in hot climatic conditions. Possible antibiofouling mechanisms of the modified nanocomposite cationite have been discussed. Since 2020, the modified silver-containing cationite has been successfully utilized for water softening systems of boiler equipment in Uzbekistan, demonstrating the suitability of the suggested facile coating technique for reducing fouling of cation-exchange resin.

Аннотация: Изучено содержание фотосинтетических пигментов в листьях березы повислой (Betula pendula Roth.) в условиях техногенных нагрузок и в фоновых условиях. Исследования проводили в березняках разнотравного типа леса в пригородной зоне г. Красноярска. Древостои, испытывающие техногенные нагрузки, расположены к востоку от города по направлению основного переноса воздушных масс, фоновые - в северном и западном направлениях от города, техногенная нагрузка на эти древостои минимальна. Содержание фотосинтетических пигментов определяли в этанольных экстрактах, расчет проводили на 1 г абсолютно сухой массы листьев. Аккумуляцию пыли листовой поверхностью оценивали по методике Ж. Детри (1973). В промытых листьях определяли содержание ионов цинка, свинца, алюминия и фтора. Показано, что содержание хлорофилла а в листьях берез из условно чистых мест произрастания несколько ниже, чем в листьях из древостоев, подвергающихся техногенным нагрузкам. Содержание хлорофилла b в листьях берез из разных мест произрастания оказалось в 2,5-3 раза ниже, чем хлорофилла а, и сопоставимо с содержанием каротиноидов. Общее содержание хлорофиллов колебалось от 5,4 до 7,3 мг/г абсолютно сухой массы, соотношение форм хлорофиллов - от 2,5 до 3, отношение суммы содержания хлорофиллов к суммарному содержанию каротиноидов - от 3,4 до 3,8. При увеличении пылевой нагрузки росло содержание всех фотосинтетических пигментов. Накопление ионов цинка в клетках листа березы отрицательно сказывалось на содержании пигментов, особенно хлорофилла а, но с соотношением пигментов не коррелировало. Значимой корреляции содержания свинца и фотосинтетических пигментов не установлено. При увеличении концентрации алюминия в листьях количество хлорофиллов и каротиноидов достоверно возрастало, связи уровня алюминия с соотношением пигментов не обнаружено. Между содержанием фтора в листовой массе и количеством разных форм хлорофилла достоверных корреляций не найдено. Полученные результаты свидетельствуют об адаптивной реакции фотосинтетического аппарата на присутствие поллютантов в концентрациях ниже пороговых значений
The content of photosynthetic pigments in silver birch leaves (Betula pendula Roth.) is studied in areas with technogenic load and in baseline conditions. The research is performed in a forb type of birch forest in the suburbs of Krasnoyarsk. The wood stands exposed to a high level of technogenic pressure are located to the east of the city in the prevailing direction of air mass movement. The reference stands are under the least technogenic pollution and grow in western and northern areas of the city. The photosynthetic pigments are determined in ethanol extracts, calculated per 1 g of absolute dry mass (a.d.m.) of the leaves. A level of dust deposition on leaf surfaces is evaluated according to the method of J. Detrie (1973). The amounts of zinc, lead, aluminum, and fluorine ions are estimated in the washed leaves. It is found that the content of chlorophyll a inside the birch leaves from a relatively clean environment is slightly lower compared to the concentration in the leaves with the technogenic load. The chlorophyll b concentration is 2.5-3 times less than chlorophyll a and is close to the amount of carotenoids. The total chlorophyll content in birch leaves from different locations ranges from 5.4 to 7.3 mg/g a.d.m., the ratio of chlorophyll forms varies from 2.5 to 3, the proportion of net chlorophyll to carotenoids is between 3.4 and 3.8. As the level of dust increases, the content of the total photosynthetic pigments also rises. The accumulation of zinc ions in the birch leaf cells has a negative effect on pigment content, especially chlorophyll a, but doesn’t correlate with the ratio of the pigments. There has not been any correlation found between the lead and the photosynthetic pigments. It is noted that the rise in the concentration of aluminum significantly affects the contents of the chlorophylls and the carotenoids, while no relationship has been discovered between the concentration of aluminum and the proportion of the pigments. The relationship between fluorine and different forms of chlorophyll is absent as well. The results indicate the adaptive response of the photosynthetic system to the presence of pollutants in concentrations below the threshold values that are indicated in the literature
