The nature of catastrophic steppe fires in Siberia, which in recent decades have been spread over thousands of hectares each year, leading to economic losses, and losses of lives and livestock, is being considered. The paper follows spring (March-May) steppe and forest-steppe fires using satellite...

The distribution of individuals of the intermediate form of Norway spruce Picea abies (L.) H. Karst., and Siberian spruce P. obovata Ledeb., distinguished according to the metric parameters of the seed scales, was studied in extensive areas of the range from the Ukrainian Transcarpathia in the west ...

An efficient system for the in vitro propagation of the endangered medicinal and winter-hardy ornamental plant, Rhododendron mucronulatum Turcz., through high frequency shoot induction from seedlings and in vitro-derived apical shoots was developed. While testing different zeatin (Z) concentrations ...

Studies of Pinus sylvestris L. forests in the impact (5-10 km) and buffer (11-40 km) technogenic pollution zones in the vicinity of a large industrial centre Usol'e-Sibirskoe of Irkutsk Oblast have been conducted in 2013-2016. Changes of biogeochemical indexes (acid-base balance, accumulation and...

The search for an optimum value to constrain boundary parameters in distribution models can be (and is) laborious and time-consuming. The accuracy of a distribution fit depends on the predetermined values of the boundary parameters. In this study, we applied the extreme value distributions derived...

The objects of the study were forest shelterbelts represented mainly by pure and mixed stands of black poplar Populus nigra L. in the Republics of Khakassia and Tyva. The sites differed according to soil conditions: southern chernozems, ordinary chernozems, sandy spilled soils. The stand structure...

The paper reviews research papers, develops recommendations for forest regulatory documents. Some deficiencies in the current regulatory framework are revealed. Traditionally, the system of normative documents had a hierarchical structure. The upper level contained basic principles and the most...

Increasing urbanization makes people study the environmental and sanative functions of suburban forests. Forest attendance of over two thousand people per day per hectare in a season is facilitated by a dense network of roads and trails in suburban forests near Krasnoyarsk, so that residents can...

The article is concerned with the discussion of the reasons for the contradictions existing in the assessment of the hydrological role of forests. The authors believe that the accumulation of new information related to seemingly well-studied processes and phenomena necessitates revisions of...

A review of the state and analysis of works related to optical processes of photosynthesis are given. Particular attention is paid to the work on the investigation of these processes in iridoplasts and chloroplasts with photonic crystal structure. From a general point of view, a photonic crystal...
