Currently there are six locations of Cretaceous continental fauna and flora in Amur region: Blagoveshchensk, Kundur and Astashikha, Gilchin, Dim, Bureinsky Belogory. Gilchin is the location of the Cretaceous dinosaurs, the potential of which still requires evaluation. The article provides new information about the history of its discovery, as well as the description of the fossils from the Gilchin collection presented in the exposition of the Paleontological Museum of the Amur Scientific Center of the Far East Branch of the Russian Academy of Sciences. The fauna of Gilchin, established by fossil bone remains, includes hadrosaurs, carnivorous dinosaurs, a dinosaur whose identity it is difficult to determine, and turtles (Trionychidae indet). Most of the definable bone remains of the collection belong to the hadrosaurs. In terms of preservation, the fossil material is close to that of the Chinese locations of Ulaga and Jiayin / Longu Shan. The article assumes similarity of the genesis of the locations of Gilchin and Jiayin / Longu Shan (China).

The search for ways to reduce the supply of Chernobyl trace cesium to agricultural plants has remained relevant in Kaluga region for many decades. This problem is particularly acute for private farmlands, in which centralized agrotechnical measures for the rehabilitation of polluted soils were not carried out. In this regard, the purpose of this study was to develop measures for the safe economic use of private farm soils, natural meadows as hayfields and pastures. We used comparative analytical, instrumental and statistical methods. The studies were conducted during 1997–2016 on the basis of the agricultural production cooperative “Lesnye Polyany” of the Ulyanovsk district of Kaluga region. The experiments were conducted on the private land of three private farms and the floodplain of the Shorochka River. Local resources were used for the experiments: activated sludge from a biological pond near the village of Ulyanovo, and ground thistle from “Sorbent” Joint-Stock Company, for which there are positive sanitary and hygienic conclusions of Kaluga Sanitary and Epidemiological Surveillance Center. Based on the study of the dynamics of changes in the specific activity of grass stand and cattle milk, a half-decrease period for contamination of bioproduction was established within 7–8 years, due to increased binding strength and physical decay of radiocesium. The seasonal dynamics of reducing the content of radiocaesium in hay in a meadow ecosystem and milk of cows from April to July during the growing season has been established. The radiomeliorative capacity of activated sludge and ground tripoli has been proven in the production of private farms.

Approbation of a new method of soil fertility testing is given in the article. To identify the biological activity of soils, it is proposed to take into account the morphometric reactions of the phytotest and to compare them with the normal mathematical distribution characteristic of the rate of reaction of a plant population homogeneous in genotype against stable cultivation conditions. Seeds of Triticum durum are used as a test object. The soils processed by biological preparations: Flora-with, Fitop-Floras in a combination with natural zeolites were tested. A hypothesis is put forward: factors that cause the normalization of the distribution of morphometric characteristics of seedlings in the phytotest contribute to the conservation of the gene pool and the full realization of the reproductive potential of the population. The new testing method is based on the use of the authorial computer matrix based on MS Excel and statistical criteria. The validity of the method was determined by the correlation of ranks obtained by summarizing the signs of optimization of cultivation conditions in laboratory and field experiments. The article points out high validity of the method, and the statistical indicators that allow an objective assessment of the mathematical characteristics of the plant population.

Assessment and prediction of the functional state of specialists in an extreme professional environment is a physiological justification for the organization of labor to maintain the high performance of specialists. The purpose of the work is psycho diagnostic and electrophysiological study of the functional state of firefighter-rescuers with different service lives in the Federal Firefighting Service of the Ministry of Emergencies in the Tver region, taking into account the daily dynamics. Materials and methods: the survey involved 235 male rescue firefighters aged 25 to 45 years with a service experience from 1 to 22 years. All subjects were divided into three groups depending on the length of service. To assess the functional state, we used a questionnaire with scales of well-being, activity and mood, and a method of heart rate variability. Results: the subjective assessment on the scale of the questionnaire was optimistic, homogeneous and quite rigid. Analysis of heart rate variability showed a more heterogeneous picture. When assessing the daily dynamics, a vagotonic shift was detected in most firefighter-rescuers. Correlation analysis revealed balanced adequate connections between the self-assessment of the functional state and the hardware diagnosis of heart rate variability only for firefighter-rescuers with 7–15 years of service experience, which corresponds to the stage of formed professionalism.

Fritillaria meleagris L. is a rare species mainly associated with floodplain forests and meadows. Conservation of populations of this species needs to consider a key aspect of its life history – prolonged dormancy (PD). In F. meleagris, this was observed during 8-years monitoring of individual plants on the protected ancient Lugg Meadow in the UK. One-year PD was most frequently observed in the population, followed by 2-year PD. Seven-year dormancy was the longest recorded. Twenty two percent of plants didn’t display PD during the observation period. Large variability in the patterns of individual plants submerging and re-emerging from dormancy in different years, suggested individual genetic heterogeneity as the main factor driving PD of the species. Three morphological states were identified in dormant plants of F. meleagris including a false dormancy in individuals which carried on growing below ground. Patterns of PD in rare species need to be studied on individually monitored plants and applied to models of population dynamics for species conservation purposes

For the first time, the method of bioclimatic modeling was used to determine the boundaries of the range of occurrence of a potential polemochoral species Avenella flexuosa (L.) Drejer. The simulation was performed by the method of maximum entropy (MaxEnt). It is shown that the conditions for the growth of this species are initially suitable (the probability of finding 0.54 and higher) in the territory of Central Russia. For comparison, the same bioclimatic modeling approach was applied for the occurrence data of Carex brizoides L. species, the polemochoral origin of which is not in doubt. It is shown that its growing places are beyond the limits of the climatic optimum (the probability of finding 0.08) in the territory of Central Russia.

Currently, palsa mires in the southern limit of circumpolar permafrost zone are characterized by an increased intensity of thermokarst processes. In the south of Nature Park Numto the cyclic character of frozen mound formation was replaced by their unidirectional degradation as a result of thaw. We analyze plant indicators of various thermokarst forms occurring in mounds: denudation spots, slumps and funnels. Depending on the stages of thermokarst and type of palsas (flat mound or large mound ones) a number of plant indicators of thawing is revealed: “the drunken forest”, the loss of dwarf shrubs and lichens and their secondary colonization, eutrophication of communities, the emergence of the “ridges” of vegetatively mobile species and others. Brown mosses and secondary colonizing Cladonia lichens with cup-shaped and club-like podetia are indicators of slow thermokarst on patches of denudation in large mounds. Meanwhile, the role of Cladonia lichens with richly branched podetia is markedly reduced. Mesotrophic communities, dominated by mesotrophic sphagnum mosses, are formed in deep funnels on large mounds under the conditions of frozen bed existence. The development of eutrophic communities indicates the release of nutrients during the melting of peat. The stages of thermokarst on the flat palsa mounds correspond to the following succession row: lichens + dwarf shrubs → hygrophyte sphagnum mosses and / or brown mosses + liverworts → hygro-hydrophyte sphagnum mosses + Warnstorfia fluitans. Reliable and the most long-term indicator of thermokarst on large mounds is the downy birch (Betula pubescens).

The purpose of this work is to identify the level of phenotypic diversity of the morphological features of Populus × sibirica leaves, including qualitative signs-phenes. To reveal the variability, the authors examined 90 trees, on which 1,350 leaves were measured in the green areas of the cities of Novosibirsk, Novokuznetsk and Berdsk. When analyzing the qualitative features, there were selected the following morphological markers: leaf pubescence, development of basal glands, leaf form, its base and apex. The conducted studies of Populus × sibirica samples showed that it is characterized by very low and low variability of the quantitative traits of a leaf. Leaf-shaped ovoid plates and leaves with developed basal glands (78–89 %) are predominant. Close indicators of averaged endogenous and individual variability reflect its cultural origin. Probably, Populus × sibirica in the Siberian region consists of several clones selected from the same hybrid family. A number of studied morphological qualitative features of a leaf, which are distinguished by the absence of endogenous variability, can be attributed to phenes: the shape of the apex and the shape of the base of the lamina, as well as the nature of the development of pubescence. The most controversial issue in the origin of Populus × sibirica remains the presence of basal glands at the base of the leaf blade.

Biogeochemical studies of plants and soil cover in specially protected natural areas are necessary for conducting background geochemical monitoring in order to determine the content of trace elements in plants of natural ecosystems and to establish the relationship between trace element composition and environmental factors. The atomic absorption spectrophotometry was used to determine the content of trace elements Mn, Fe, Zn, Cu, Cr, Co, Ni, Cd, Pb in wild herbaceous plants and the root layer of soil in the Nizhny Kama National Park (Kama valley and its tributaries). Species with a high content of Ni were found. High concentrations of Fe, Cr, Pb in the phytomass of mosses were revealed, which may indicate their aerogenic supply from nearby industrial enterprises. It was established that the soil cover of the national park within the Yelabuga region is characterized by an increased content of Mn and Co. The trace elements that are vigorously absorbed by plants, as well as species characterized by high biogeochemical activity have been identified – Aegopodium podagraria L., Fragaria vesca L., Paris quadrifolia L., Anemonoides ranunculoides L., Dicranum Hedw
