Article
Full-text available
The article contains a comparative analysis of the taxonomical structure of the weedy species composition (segetal flora) in eight regions of Russian Federation: Leningrad, Novgorod, Vologda, Rostov and Sverdlovsk Provinces, Udmurt Republic, Republic of Bashkortostan, and Altai Territory. The segetal flora comprised weeds of cereals, root crops and...

New data on the phylogeny of four rare and endemic species of Ranunculus L. (sect. Ranunculastrum DC.) of western Pamir-Alai, one of which is new to science, have been obtained. Ranunculus tojibaevii sp. nov., from the Baysuntau Mountains, Western Hissar Range of Uzbekistan, is described. The new species is closely related to R. botschantzevii Ovcz...

The results of the long-term monitoring (from 2008 to 2018) of thermal conditions have been applied to assess the ecotopological differentiation of vegetation in the exposure-related forest-steppe of Transbaikalia. Significant differences are revealed between thermal conditions on northern and southern slopes, as well as between different kinds of...
Article
Full-text available
The indirect collecting of quatitative data on the rates of the main abiotic factors by the parameters of the vegetation opens up the possibility of identifying ecological ranges for poorly studied hard-to-reach species, especially rare high-mountain plants. The ecological plasticity of the genus Ranunculus L. in contrasting conditions of high moun...

Indicator values are becoming an increasingly popular tool in basic and applied botanical research: more than 55 original phytoindication systems, including about 200 optimal and range scales for various environmental factors, are known. This paper describes seven methods for calculating the phytoindication optimum of a taxonomical list: averaging...
Conference Paper
The long-term soil temperature monitoring in the area of more than 550 km in length within the region of Transbaikalia has been carried out. Sites for the monitoring were represented by the forest-steppe vegetation of different ecotopological and ecogeographical patterns. It was revealed that the dynamics of temperature regimens are highly synchron...

The data on the composition, ecology and occurrence of vascular plants of a specific (local) flora in the vicinity of Chokurdakh village (147°53' E, 70°38' N), obtained from the second inventory of the flora in July–August 2013–2014, 45 years after the previous one in 1969 (Boch, Tsareva, 1974). The presence of 154 (69% of the total number of speci...

На основе 14348 геоботанических описаний из фитоценотеки «Database of Siberian Vegetation (DSV)» с использованием интегрированной ботанической информационной системы IBIS определены индивидуальные экологические ареалы 43 представителей рода Ranunculus в Сибири в системе факторов Д.Н. Цыганова (1983). Ареалы показали значительное своеобразие в сочет...

Questions: Vegetation-plot records provide information on presence and cover or abundance of plants co-occurring in the same community. Vegetation-plot data are spread across research groups, environmental agencies and biodiversity research centers, and thus, are rarely accessible at continental or global scales. Here we present the sPlot database,...
Article
Full-text available
We investigated changes in the structure of plant communities (floristic composition and species activity) under the influence of anthropogenic and technogenic factors. The studies were conducted in close proximity to rapidly developing surface coal mines and areas of intensive agriculture (Karakanskiy ridge, Kemerovo Region, Russia). The Karakansk...
Article
Full-text available
Patterns in the organization of psammophyte vegetation of sandy steppes have been studied in Orenburg oblast. Using cluster analysis with different similarity indices, 122 relevés have been analyzed. The best cluster differentiation is achieved by the use of a Sokal/Sneath coefficient. Five types of plant communities have been distinguished and cha...
Article
Full-text available
The criteria for assessing conservation categories of rare species are not identical in drafting the red lists of Russia and the IUCN. By the example of genus Saussurea (Compositae), we have shown that the conservation measures for some endangered species do not match their state. We conducted indicator analyses on two factors of more than 9000 rel...
Conference Paper
Full-text available
The spatial distribution analysis of Ranunculaceae Juss. in Republic Kazakhstan is carried out. While revealing the principal aspects of distribution of Ranunculaceae species and genera in connection with their ecological and belt-zone differentiation within the limits of floristic districts of Kazakhstan the opportunities of application of compara...
Article
Full-text available
Plant communities developed on four abandoned fields in the South-Ural region have been studied (1 field – 55°50'16.95"N, 57°11'23"E; 2 –56°06'21"N, 56°40'06"E; 3 – 55°41'18"N, 56°09'31"E; 4 – 55°00'22"N, 57°03'20"E), and the reforestation process throughout all of key sites is observed. Totally, we collected 106 geobotanical relevés and further cl...

An analysis of indicator values of four Saussurea DC. species, S. baicalensis (Adams) B. L. Rob., S. frolowii Ledeb., S. salicifolia (L.) DC., and S. schanginiana (Wydl.) Fisch. ex Serg., have been carried out by the method of indicator scales of soil moisture and nutrient availability and salinity in more than 1600 relevés. The size of their ecolo...
Article
Full-text available
The local flora method has been used by Russian botanists for studying vast wilderness areas. The method strives to determine the total flora within a certain limited area and provides comparable data for spatial comparisons between different locations and temporal comparisons at the same location. Complete vascular plant diversity was sampled in 2...

Проведён кластерный анализ 57 локальных флор Северной Якутии по сходству видового состава и соотношений долготных и широтных групп и фракций. По соотношению фракций определены долготные и широтные типы флор. Визуализация на карте кластеров, сходных по разным показателям флор, позволяет сравнить выделы, полученные в результате кластерного анализа, с...
Article

The widespread types of larch forest of the Middle Siberia of Northern Boreal Subzone near the Tura settlement were singled out. Leading ecological factors forming diversity of forest types were examined by means of DCA-ordination. Floristic composition and structure of forest communities were studied using IBIS-software. The completed study showed...

Full-text available
The paper aims to show that mediate indication of environmental acidity conditions in hydromorphic habitats in the West Siberian Plain is possible by means of using indicator values for soil moisture and nutrient factors as substitute predictors. These factors are viewed as interrelated for plant communities located in the wetlands in the West Sibe...

A first variant of Database of Siberian Vegetation (DSV; GIVD ID AS-RU-002) was created in 1994 in the Laboratory of Geobotany of the Central Siberian Botanical Garden of the Siberian Branch of RAS (CSBG SB RAS). Now it is located at the Geosystem research laboratory of CSBG SB RAS and in Tomsk State University. DSV contains geobotanical relevés fr...

The concept of equivalence classes and factor sets known from set theory is applied to the theory and practice of botanical studies. The properties of taxonomic, typological, and gradient factor sets and their connection with a comparative floristic and phytoindicative analysis are considered. The enlarged groups of regimes are proposed for ten eco...
