The North American ash-leaved maple is one of the most dangerous invasive species in Russia. However, due to the high seed production and the ability to grow in the environmentally unfriendly territories, it spread widely in Moscow, forming the tangle of tilted and curved trees, which are not much decorative. The rapid reduction of the ash-leaved maple population may exacerbate the adverse environmental situation in the city. The study of the species’ biomorphological features, as well as the consequences of the spontaneous pruning performed by the landscapers, makes it possible to issue recommendations on adjusting the crowns of curved and tilted trees, multi-stem trees, as well as on improving the appearance of tangles. Thanks to the dormant buds, Acer negundo easily tolerates the most radical variants of rejuvenating pruning, allowing to reduce the crown of trees to a height of 3–4 m, to form low-growing trees with a height of 1.5–2 m, as well as living thickets, to correct the crown of tilted and bent trees by shortening the trunk to a powerful shoot arising on the trunk from a dormant bud, and removing, in case of a bifurcation of the trunk, the most deflected trunk.

Oligotrophic ridge-hollow and ridge-hollow-pool complex mires are widely distributed in the central part of West Siberia, including many oil fields of the Middle Pre-Ob region. The article considers the dynamics of re-vegetation of oil and salt-contaminated areas of these mire types subjected to reclamation. Survey materials for 2–3 years and 15 years after reclamation allow to identify the main trends in vegetation restoration in the short and medium term. The reversible oligotrophication of ridges manifests in a relative decrease in the participation of the meso-eutrophic species on contaminated mire sites. In the hollows, however, the similar trend can be traced only in relation to oil-contaminated sites, whereas in the salt-contaminated hollows, the strong eutrophic conditions last. In the medium-term perspective, most typical oligotrophic hollow species, with the exception of Eriophorum russeolum and Oxycoccus palustris, were unable to recover. In the course of dynamic changes in the vegetation, the leading role in recovery successions gradually passes to mesotrophic and eutrophic species possessing massive root systems and aerenchyma – Eriophorum angustifolium, Phragmites australis, Carex rostrata, etc. Restoration of the moss layer is several years behind that of the grass layer, and due to the lack of competition, the participation of liverworts in it is of great importance, especially in salt spills. At the same time, among mosses as in the case of vascular species mesotrophic components are the main dominant ones15 years after reclamation.

The article is devoted to the potential of advanced development of the steppes of Russia. The existing steppe land-use is considered as the result of four megaprojects: “Stalin’s plan for the transformation of nature”, Tselina, radical reforms of the 1990s, and Russia’s accession to the WTO. The sustainable ideological legacy of these mutually exclusive and unfinished projects were: extremely difficult to change the type of use for arable land, priority of compensatory forest use in forest-deficient regions, prohibition of grassland farming systems, idealization of the role of shelter forests and reservoirs, underestimation of ecological-economic services by steppes, especially carbon deposition. The described potential of advancing development of the steppe zone, as well as its natural, historical and scientific prerequisites for its implementation justify the need to develop and implement a national project entitled “Russia’s Steppes: Yield, Diversification of Land Use, Stable Productivity, Environmental Rehabilitation”/ The article outlines the basics of its program. The study of steppe is considered as a center of convergence of sciences for the development and implementation of such a project. The essence of the project is to bring the structure of agricultural land and steppe land use into compliance with the natural prerequisites with the achievement of long-term non-destructive use and a fundamental increase in hectare output.The main components of the project are: equal rights of natural zones in the agrarian policy, adjustment of WTO obligations to support agriculture, new steppe land management, intensive field crops technologies, marbled meat of adaptive cattle breeds and ranching, carbon deposition, steppe reviling, steppe ecotourism.

Sleep disorders are one of the significant problems in the modern society. Current research is on the lookout for the nonpharmacological ways to improve sleep quality and slow wave brain activity that plays a crucial role in homeostasis and cognitive functions. One of the promising approaches is acoustic stimulation that is phase-locked to deep sleep EEG rhythms. It was already shown that such stimulation improves slow wave brain activity. This article describes Dreem: a wireless consumer device that performs acoustic sleep stimulation in home conditions. The device has dry EEG electrodes, photo sensor for pulse oximetry, and an accelerometer. The inbuilt software detects deep sleep, performs audio stimulation on the ascending slope of the delta wave and does automatic sleep staging. In the pilot study of the device, three subjects made 10 to 24 recordings of night sleep with EEG recording and stimulation. The raw data recorded by the device is available to the user and is sufficient for sleep staging and basic sleep analysis. Automatic hypnograms reflect the structure of a normal night sleep. EEG averaged by the stimulation markers demonstrated the high efficacy of slow wave detectors and placement of stimulations on the ascending slope of a delta wave. Dreem device is of interest for the sleep researchers as an easy to use tool for an out-of-lab data acquisition.

In model incubation experiment the effect of various agrocenoses on CO2 production and nitrogen-mineralizing ability of the soil to accumulate nitrate nitrogen (N-NO3) was investigated. It was shown that the rates of mineralization of soil organic matter decreased from the first record taken to the last in the following order (in percent): 57 → 63 → 68, further observation of CO2 emissions led to a smoothing of redox reactions. The use of mineral fertilizers in comparison with agrocenoses without fertilizers increased CO2 emissions by 15–24%, depending on the studied variant. It was noted that the agrocenosis with the alienation of aboveground biomass of straw exerted the least load on the total mineralization of soil organic matter – on average, in two levels of fertility, it was 489 mg C / kg. The use of analysis of variance in the experiment did not reveal significant differences in the interaction of signs on the accumulation of N-NO3, however, the solution of correlation and regression dependences contributed to finding a close relationship. It was determined by the capabilities of leached chernozem to compensate losses and restore the carbon-nitrogen potential of the soil. A similar consequence increased in the agrocenosis with mineral fertilizers and with a greater flow of aboveground and underground plant residues into the soil, the maximum CO2 emission was registered in the variant 634 mg C / kg, and high statistical indicators of the studied signs were established.
在模型培养试验中,研究了不同农藓类植物对土壤CO2产量和氮矿化能力的影响,并对土壤积累硝态氮(N-NO3)进行了研究。结果表明,从第一次记录到最后一次记录,土壤有机质的矿化率依次为:57→63→68,进一步观察CO2排放导致氧化还原反应趋于平滑。与不使用化肥的农肥相比,使用矿物肥料增加了15-24%的二氧化碳排放量,具体取决于所研究的品种。在两个肥力水平上,秸秆地上生物量异化的农病对土壤有机质总矿化负荷最小,平均为489 mg C / kg。通过方差分析,本试验未发现各性状间N-NO3积累的交互作用存在显著差异,但通过对相关依赖和回归依赖的求解,发现了密切的关系。这是由淋溶黑钙土补偿损失和恢复土壤碳氮潜力的能力决定的。在施用矿质肥料和地上、地下植物残体大量进入土壤的情况下,土壤污染的结果也有所增加,最大CO2排放量为634 mg C / kg,并建立了研究迹象的高统计指标。

Using the traditional research methods, based on the example of local and cultivated representatives of the Tacamahaca (Spach) Penjkovsky subgenus growing in Russia and neighboring countries, the concept of a species in poplars (genus Populus L., Salicaceae) has been developed. It is suggested that the sections of black poplars (Aigeiros Duby) and balsamic poplars (Tacamahaca Spach) in Eurasia form a single supraspecific system with a common gene pool, which is very similar to syngameon. The taxonomic species that make up such a system are different dynamic states of this system and exist in the equilibrium state between natural selection, which forms and preserves the specifics of each dynamic state, and gene flows from other taxonomic species. Such a system can also be considered as a large Linnaean species represented by many subspecies or even geographical and ecological races. The use of molecular genetic methods for the taxonomic species study in the Populus genus is difficult due to the powerful flow of genes between the species, since the species differ in a small number of genes responsible for adaptive characters. The sections of the subgenus Tacamahaca poplars are ecological. The combination of species in these sections is not so much about the unity of their origin, but about the common growing conditions: black poplars tend to grow in lowlands, while the balsamic poplars tend to grow in the mountains, with which the poplars’ diagnostic characters are associated. In nature, belonging to a certain section is more profitable than the intermediate state, but in cultivation and in the urban environment, the opposite situation is observed.

The purpose of this work was an ecological assessment of the habitats of Carex brizoides L. on the Eastern border of the area on the indicator scales of D. N. Tsyganov (1983) using the computer program EcoScaleWin. To determine the ecological conditions of growth of C. brizoides, three coenopopulations were analyzed: on the margin of a mixed forest, forest of black alder and in cutting. Analysis of the ecological amplitude of the species on the scales of D.N. Tsyganov showed that the species is a stenobiont to the complex of climatic factors, a hemistenobiot to the complex of soil factors and a euryvalent for the light-shading factor. The degree of use of the ecological potentials of the species in the studied C. brizoides population is narrow in the following modes – scale of climate continentality, ombroclimatic scale of aridity and humidity, riches of the soil, nitrogen value of soils, soil acidity, Illumination-Shading (coefficient of ecological efficiency no more than 10%) and quite wide in – thermoclimatic end cryoclimatic scales, soil moisture (coefficient of ecological efficiency from 25.0% to 40.9%).

Tsyganov尺度上的生态振幅分析表明,该物种对气候因子的复杂性是一个狭窄生物,对土壤因子的复杂性是一个半狭窄生物,对遮光因子是一个泛价生物。在气候大陆性尺度、干湿气候尺度、土壤富余度、土壤氮值、土壤酸度、光照-遮阳(生态效率系数不大于10%)等模式下,本研究物种生态潜力的利用程度较窄;在热—冷气候尺度、土壤湿度(生态效率系数25.0% ~ 40.9%)等模式下,物种生态潜力的利用程度较宽。
