Аннотация: We evaluated the balance of production and decomposition in natural ecosystems of Pinus sylvestris, Larix sibirica and Betula pendula in the southern boreal forests of central Siberia. using the Yenisei transect. We also investigated whether anthropogenic disturbances (logging, fire and recreation pressure) influence the carbon budget. Pinus and Larix stands up to age class VI act as a net sink for atmospheric carbon. Mineralization rates in young Betula forests exceed rates of uptake via photosynthesis assimilation. Old-growth stands of all three forest types are CO2 sources to the atmosphere. The prevalence of old-growth Larix in the southern taiga suggests that Larix stands are a net source of CO2. The CO, flux to the atmosphere exceeds the uptake of atmospheric carbon via photosynthesis by 0.23 t C.ha(-1).yr(-1) (47%). Betula and Pinus forests are net sinks, as photosynthesis exceeds respiration by 13% and 16% respectively. The total carbon flux from Pinus, Larix and Betula ecosystems to the atmosphere is 10 387 thousand tons C.yr(-1). Net Primary Production (0.935 t-C.ha(-1)) exceeds carbon release from decomposition of labile and mobile soil organic matter (Rh) by 767 thousand tons C (0.064 t-C.ha(-1)), so that these forests are net C-sinks. The emissions due to decomposition of slash (10 1 thousand tons C; 1.0%) and from fires (0.21%) are very small. The carbon balance of human-disturbed forests is significantly different. A sharp decrease in biomass stored in Pinus and Betula ecosystems leads to decreased production. As a result, the labile organic matterpool decreased by 6-8 times; course plant residues with a low decomposition rate thus dominate this pool. Annual carbon emissions to the atmosphere from these ecosystems are determined primarily by decomposing fresh litterfall. This source comprises 40-79% of the emissions from disturbed forests compared to only 13-28% in undisturbed forests. The ratio of emissions to production (NPP) is 20-30% in disturbed and 52-76% in undisturbed forests.

recreation -- phytoindication -- ruderal groups -- trampling -- glade-clump communities

Аннотация: The influence of recreation activity on grass cover was studied in a herbaceous birch forest within a territory of city development. Effects of the activity depended on size and arrangement of recreation sites. It was found that most of the forest was at the second stage of degradation, while degradation of forest edges was considered as intermediate between the second and third stages. Forest edges and glade-clump communities play a particular role in maintaining the stability of recreational forests. These ecotones are both barriers preventing introduction of alien plant species into a cenosis and centers of dissemination of ruderal and meadow species.

Ceratocystis laricicola -- Pinus sylvestris

Аннотация: A method for estimation of tree's condition on activity of defence response in phloem was checked in Pinus sylvestris L. stands located near Krasnoyarsk (Siberia, Russia). The length of necrosis caused by inoculation of phloem of living tree by Ceratocystis laricicola Redf. et Minter was used as the parameter being measured. The field experiments were carried out in two even-aged (about 60 years) pine stands that were approximately equal on structure, productivity, density and recreation loading, but differentiated on degree of industrial pollution. The two permanent sample plots (SP) were founded in the severely polluted stand. The other two SP were placed in the unpolluted pine forest. The amount of pine trees within each SP varied from 200 to 250. From 22 up to 37 pine-trees selected randomly within every SP were inoculated with C. laricicola mycelium (test 1) and its extract (test 2). One inoculation hole per one tree (diameter 7 mm) was made in stem at a height of 1.3 m. Application of the both agents caused necrosis in phloem around the place of inoculation. In the case of fungal inoculation (test 1), the average length of necrosis in the unpolluted forest exceeded significantly the same parameter in the polluted stand: 51.7-79.4mm and 39.4-41.3mm, correspondingly. The action of the fungal metabolites caused the opposite results: in the unpolluted stand the average size of necroses was smaller in comparison with this parameter in the polluted stands 44.5-15.3 mm and 57.9-61.8 mm. The reasons of this difference are discussed. The both agents (C. laricicola mycelium and its extract) were suitable to reveal the difference of tree's condition in polluted and unpolluted pine stands. The application of fungal extract is more preferable in comparison with fungal mycelium because of smaller variability of necrosis size. Besides, the application of extract allows controlling inoculum dose and excludes the dangerous of spreading infection in forests.

Аннотация: The vegetation cover characteristics of anthropogenically disturbed birch stands of Krasnoyarsk forest-steppe are studied. The research purpose is to study the current state of under-story vegetation cover of the birch stands, which have been exposed to recreational and anthropogenic impacts for a long time, as well as to assess the degree and nature of its change over the 12-year period since the last research. The studies were carried out on the sample plots laid out in mixed herbs birch stands. Cenosises are characterized by V-VI age classes, II-IV quality classes, and 0.6-0.9 density of stocking. The birch stands are located in the main transfer of Krasnoyarsk industrial emissions. Phytocenoses were under significant anthropogenic and recreational impact for a long time. At each facility, 30 sites (1 m(2) each) were laid, where species composition, horizontal and vertical structure, projective cover and occurrence of undergrowth and forest live cover species were assessed. The comparative analysis of floristic lists was performed using the Sorensen-Czekanowski coefficient (K-sc). The degree of species diversity was estimated by using the Shannon index; the degree of recreational transformation - synanthropization index. Cuttings were taken from 10 sites (20 x 25 cm each) for recording the phytomass stock of forest live cover on each sample area. Plants were cut off at the litter level, sorted by species, dried and weighed. Rating scales of digression were used to study the recreation influence. The degree of anthropogenic impact was determined by the content of toxic ingredients in plants of living ground cover. It is found that the toxic elements concentration in plants does not reach excessive values at which homeostasis disturbance happens. It was concluded that the changes in vegetation cover observed in 2017 in relation to the state of 2005 are more due to recreational than anthropogenic impact; which changed due to the introduction of a new technology at the JSC "RUSAL Krasnoyarsk Aluminum Plant", which made it possible to reduce toxic industrial emissions. According to the study results, the species composition of the undergrowth and forest live cover was determined, the features of its change over a 12-year period were revealed. It is noted that species diversity has decreased and the proportion of synanthropic species has increased across all plots. Total forest live cover phytomass and individual species phytomass are determined at each plot. The regularities of change in different species contribution to the total stock of phytomass, depending on recreational impact changes, were identified. The ground cover recreational digression stages are determined by analyzing the changes in species diversity, the quantitative ratio of ecological-cenotic groups, the structure and the absolute value of phytomass.

Diameter growth rate -- Industrial air pollution -- Urban community gardening -- Woody species

Аннотация: The research undertaken focused on trunk diameter growth dynamics of seven woody species widely used in urban community gardening in Siberian cities: Picea pungens, Betula pendula, Ulmus pumila, Populus balsamifera, Sorbus aucuparia, Padus maackii, Malus baccata. Diameter growth rate was used as indirect indicator of the extent to which industrial pollutions may affect woody species in community gardening. Greening of large industrial city Krasnoyarsk was under study. Five sample sites differing in content of industrial pollutions were established within the districts of the city. It was reviled that in the Downtown greenings being under heavy recreation and vehicle-caused pollutions S. aucuparia,P. maackii, P. pungens, B. pendula and P. balsamifera could be successfully used rather than U. pumila and M. baccata. Greenings heavily polluted by nonferrous metallurgy enterprises should be composed with tolerant M. baccata, B. pendula, U. pumila and P. maackii, and; at that time P. pungens, S. aucuparia and P. balsamifera could not be recommended for planting hear. In greenings heavily polluted by heat power plants and chemical (pulp and paper) enterprises should be composed with tolerant P. pungens, S. aucuparia, P. maackii. B. pendula, U. pumila, P. balsamifera, M. baccata could not be recommended for planting there. Greenings, if planted in accordance with this recommendations, can be highly effective in fulfilling environmental, protective, sanitary, and esthetic functions in industrial cities. It should be taken into account in the implementation of management programs and development strategies for Siberian urban greenings. © 2020 Lesotekhnicheski Universitet (University of Forestry).
