Outbreaks of the phytophage lead to chronic weakening of trees and reduction in their growth and seed germination capacity. From 1950 to 2004, studies of gypsy moth in Tyva were carried out by researchers taking part in forest health surveys headed by such scientists as O. A. Kataev, V. P. Grechkin, G. I. Golutvin, V. A. Sevastyanyuk, N. I. Berdnikov, V. V. Popov, A. A. Liberman, and others. The researchers have described the phenology of the gypsy moth and its regional morphological and bioecological features. The present work attempts, based on the generalization of the accumulated data on gypsy moth in Tyva, to restore the chronology of pest outbreaks, show their spatial coverage, and propose approaches to their reconstruction over a longer period in the Republic of Tyva. The results of the study showed that in Tyva, four outbreaks of gypsy moth, which occurred in 1950, 1969–1983, 1993–2004, and 2018, were detected. Outbreaks were of a protracted nature and simultaneously covered up to 80 % of forest districts (in some years, the area affected by the pest reached half a million hectares or more). The most intense outbreaks were observed in the central part of the Republic, in the warm conditions of larch and birch forests – in the Kaa-Khem, Tandinsky, Tes-Khem, and Shagonarsky forest districts","PeriodicalId":36334,"journal":{"name":"Journal of Siberian Federal University - Biology","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78881809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A complete floral survey of the area is unattainable at present because it is a vast wetland with very few roads. The study is aimed at evaluating the current state of local flora and vegetation, and identifying plants and plant communities that require protection. Main types of phytocenoses in the Aleksandrovskiy wildlife area were described, which include small-leaved, light-coniferous and broad-leaved forests, willow coppices, cereal-forb dry meadows, sedge-reed floodplain meadows mixed with halophyte communities, pine-subshrub-sphagnum raised bogs (riams), and semi-aquatic vegetation. Birch, aspen and aspen-birch bracken, forb and cereal-forb meadows predominate in the surveyed area. The floral diversity of the site amounts to 410 species of vascular plants, with 80 found in Vikulovo District for the first time. New sites for 10 vascular plants, one moss and one lichen species included in Red Data Book of Tyumen Oblast were found, among them Cypripedium calceolus L., Lobaria pulmonaria (L.) Hoffm. included in Red Data Book of the Russian Federation. Fourteen species which are relatively rare in Tyumen Oblast were registered.

Concentrations (ng/g of fresh mass) and contents (ng/organ) of different forms of cytokinins were determined in shoots and roots of barley plants by immunoassay. It was shown that under phosphate deficit the maintenance of root growth, inhibition of root branching and decline in shoot mass of barley plants (Hordeum vulgare 'Prairie') was due to decline in shoot cytokinins and their accumulation in the roots. Protonophore carbonyl cyanide-m-chlorophenylhydrazone as an inhibitor of secondary active transport leveled off hormonal reaction to phosphate deficit: it prevented accumulation of cytokinins in roots, increased their content in shoots and changed the percentage of zeatin and its derivatives in total cytokinin content in roots and shoots. A data analysis showed that in roots, protonophore did not change significantly the content of ribosides and nucleotides of zeatin, while uptake of free zeatin by cells was significantly affected by the protonophore and its content decreased dramatically.

Ogorodnikova","doi":"10.17516/1997-1389-0377","DOIUrl":"https://doi.org/10.17516/1997-1389-0377","url":null,"abstract":"A facility for disposal of toxic substances had been functioning in Kirov Oblast between 2006 and 2015. Destruction of phosphorus-containing substances resulted in formation of inorganic phosphorus compounds, which could enter the environment as components of gaseous emissions. The aim of the present work was to study the spatial patterns of accumulation of phosphorus compounds in the needles of Pinus sylvestris L. in the production area. The study was carried out at monitoring sites, which were represented by forest communities (southern taiga subzone) located at different distances from the pollution source (0.96–9.63 km). The total phosphorus in second-year pine needles was determined by the spectrophotometric method. During the research period (2011–2017), total phosphorus in the needles of P. sylvestris varied between 730 and 2229 μg/g. Based on results of cluster analysis, the sites were classified into two groups, which differed in levels of phosphorus accumulation in the needles of Р. sylvestris. The first group included sites with increased accumulation of total phosphorus in pine needles, which were located near the source of pollution in the direction of the prevailing winds. In sites belonging to the second group, the needles contained reduced amounts of phosphorus compounds. During the research period, variations in the amount of phosphorus in pine needles followed a similar pattern. From 2011 to 2016, the accumulation of phosphorus in the needles increased at monitoring sites of both groups. A decrease in total phosphorus in needles in 2017 was caused by a decrease in the release of phosphorus compounds to the environment and the involvement of accumulated phosphorus in the life processes of P. sylvestris. The increased accumulation of phosphorus compounds in needles in the sites near the source of air pollution was not favorable for vital processes of P. sylvestris needles and resulted in a reduction in their lifespan. Thus, the needles of P. sylvestris can be used as an accumulative indicator in areas affected by industrial air pollution by phosphorus compounds","PeriodicalId":36334,"journal":{"name":"Journal of Siberian Federal University - Biology","volume":"56 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75196938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Heavy metals (HM) are among the most common technogenic pollutants that may negatively affect the functioning of the Arctic's soil-based terrestrial ecosystems. There is almost no research on the actual HM content in the soils of Novaya Zemlya (NZ), and the purpose of this work is to assess the HM content in the soils of Severny Island in the NZ archipelago. The study was performed at Russkaya Gavan, Ledyanaya Gavan, Blagopoluchiya Bay, and Cape Zhelaniya. The soil cover in the northern part of Severny Island has a mosaic structure. On Severny Island, Cryosols (Loamic) are the most common soils among the soils studied in this work. Soils of the study regions on Severny Island are mostly loamy and clayey. The proportion of physical clay increases down the profiles. All study soils of NZ are alkaline and highly alkaline. In general, study soils have an acceptable level of HM contamination. The weighted average HM gross content in them varies insignificantly; however, the following elements exceed their threshold concentrations: Fe (1.1 clarke) – Russkaya Gavan bay; Fe (1.2 clarke), Cr (1.1 clarke), V (1.1 maximum permissible concentration (MPC)), Ti (1.1 clarke) – Blagopoluchiya bay; Fe (1.3 clarke) – Ledyanaya Gavan bay. This, apparently, is caused by their high contents in the soil-forming rock.

Lake Beloye is a regional natural landmark. In total, 36 species of 22 genera, 9 families, 4 orders were identified. Cladocera constitute 67 % of the species. The major species are Daphnia magna, Brachionus plicatilis, Daphnia pulex, Daphnia longispina, Megacyclops viridis, Ceriodaphnia reticulata, Chydorus cf. sphaericus, Simocephalus expinosus, Acanthodiaptomus denticornis, Arctodiaptomus baсillifer, Moina macrocopa, Keratella quadrata, Brachionus quadridentatus brevispinus, and Daphnia hyalina. The main abundant species in two lakes, Beloye and Arzhaan, is D. magna, which has been the dominant species in Lake Beloye for decades. The zooplankton of Lakes Beloye and Arzhaan include Macrotrix tabrizensis, a rare species, which is known to occur only in one Russian region – Tyva. Tretocephala ambigua lives in Lake Beloye. In the study period, we observed an increase in the abundance of zooplankton: by a factor of 6 in Lake Beloye and by a factor of 2 in Lakes Kisloe and Arzhaan. We believe that this is a consequence of an increase in organic load on water bodies, resulting from shallowing of the lakes and human impact. The occurrence of the species such as Moina macrocopa and Brachionus quadridentatus brevispinus, which inhabit water bodies rich in organic matter and have not been previously detected in the study lakes, confirms this assumption. Cladocerans, which have a high filtration capacity, remain dominant in Lakes Beloye and Arzhaan, and this is beneficial for the lakes. The increasing abundance of Brachionus plicatilis in Lake Kisloye performs a compensatory function in the processes of natural self-purification. At the same time, the fact that species rare for the fauna of Russia have been constantly found in the study lakes indicates the presence of favorable conditions for their development and life, which further increases the value of these unique natural environments","PeriodicalId":36334,"journal":{"name":"Journal of Siberian Federal University - Biology","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80386050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
