Spatial Patterns and Irregularities of the electoral data: general elections in Canada

Dissertation submitted in partial fulfillment of the requirements for the Degree of Master of Science in Geospatial Technologies.Democratic elections are one of the most important social phenomena of the last centuries. Countries which publish elections results on the polling station level provide a valuable source of data for different groups of scientists like geographers and statisticians. In this work, we combined geographical and statistical analysis, pursuing a goal of defining the spatial patterns and irregularities of the electoral data. From theoretical point of view, it will help to find out if the electoral behavior has any spatial dependency. From practical perspective, it can give a new insight about the electoral fraud detection. We have applied a set of statistical methods to estimate the distribution and variability of the electoral behavior in space and time for different geographic units. Canada was selected as a study area because it is an old democracy where the elections are considered being fair, and all the necessary data are available

A new monotypic genus of cobweb spiders from the Russian Far East (Araneae, Theridiidae)

A new theridiid spider, Knoflachia kurilensis gen. et sp. nov., is described from the Kuril Islands (Kunashir). The new genus belongs to the ‘Anelosimus clade (clade 24)’ of Agnarsson (2004). A pair of raised, fused setal sockets on the cheliceral promargin adjacent to the fang base was found to be another synapomorphy of all the ‘distal theridiids’ (the ‘elongated central claw clade (clade 33)’: argyrodins, ‘Anelosimus clade’ and theridiins). Knoflachia kurilensis sp. nov. demonstrates a male polymorphism similar to some Anelosimus Simon, 1891 species (e.g., A. studiosus (Hentz, 1850))

Анализ ассортимента древесно-кустарниковых растений, используемых в озеленении г. Саратова

The article deals with the history of green space expansion in the city of Saratov based on comparative analysis of the range of green spaces for 1966, 1998, and 2017. The authors note the expansion tendency of the wood species range applied in city landscaping due to the inclusion of invasive plants and decorative forms of trees and bushes. The results of a comprehensive assessment of the current state of the range of plants at the sites of urban landscaping and long-term observations of them allowed determining the types and varieties of trees, shrubs, and lianas, which had successfully adapted to the urban environment states. The authors have developed a broad range of plants, which includes 138 names of tree and bush species recommended for application on landscaping sites of various categories in Saratov.El artículo considera la historia de la construcción verde en la ciudad de Saratov, se realiza un análisis comparativo de la variedad de espacios verdes para 1966, 1998 y 2017.

Humification and Humic Acid Composition of Suspended Soil in Oligotrophous Environments in South Vietnam

Humification is considered to be a global process that is implemented in soils and organic sediments and also in natural water and air. The term “suspended soils” has become increasingly common in recent years. Suspended soils are defined as the part of the organic matter that has not undergone the full decomposition process and has not turned into the humus of terrestrial soils. Suspended soils were shown to contain higher total nitrogen, phosphorus, and potassium contents than the forest soil, but the moisture content in suspended soils was significantly lower. Our study of the structural composition of humic substances in suspended soils was conducted with an aim of evaluating the humification rates and structural composition of humic acids in the suspended soil in tropical forests of South Vietnam. Soil samples from three selected areas were investigated: the soil under phorophytes (mineral soil presented by samples of topsoil of the typical dry savanna landscape) and two soils from epiphytous formations. Samples were collected from savanna-type sparse communities, located on oligotrophous plains in Phú Quốc Island (South Vietnam) in 2015. General properties of the soil and the elemental composition of suspended soils were determined, and the humic substance chemical composition was evaluated using solid state 13C-NMR. Data obtained showed that the pH of the soils under phorophytes was higher than in the suspended soils; basal respiration did not tend to change indices between soils under phorophytes and suspended soils, but the suspended soil was less enriched by nitrogen than the soil under phorophytes. This can be related to the total amount of organic matter exposed to humification in various soils and to the presence of an essential portion of mineral particles in the soil under phorophytes. Data on elemental composition of the humic acids (HAs) indicated that one method of humification is implemented in all three soils that were investigated. The humic acids of the phorophyte soil showed the same content of aromatic fraction as the suspended soil. The most comparable soil type in terms of humic substance composition is Cambisols from humid forests of subboreal and subtropical zones. The humification process implemented in suspended soils showed the absence of mineral compounds or mineral fine earth, which indicated that humification in conditions of pure organic substrates can result in formation of deep humified organic matter, as shown by humic acids with an essential aromatic fraction content

Cellular Growth in Aerial Roots Differs From That in Typical Substrate Roots

Background and Aims: In the roots of most vascular plants, the growth zone is small, the meristem and the elongation zone are sharply separated, and only meristematic cells divide. This statement is based almost entirely on studies with soil-rooted plants. Whether aerial roots of structurally dependent (=epiphytic/hemiepiphytic) species differ is virtually unexplored. Methods: Growth of aerial roots in 20 structurally dependent plant species from eight families was studied ex situ. In 12 species, we studied the anatomical structure and distribution of cortex cell lengths and rhizoderm in the growth zone. Key Results: All the studied aerial roots had an open apical meristem, and mitoses were not restricted to the meristem. In contrast to belowground roots, relative growth rate did not strongly increase upon transition to the elongation zone, while elongating growth was often prolonged. Still, the relative growth rate was lower than in belowground roots in soil, and in different species, it did not change considerably compared to each other. Conclusions: A distinct elongation zone with rapid cell growth was missing in the studied aerial roots. Rather, there was a growth zone in which division, growth, and differentiation co-occurred. We observed a generally low relative growth rate in aerial roots and a surprisingly similar initial growth pattern in spite of the diversity in taxonomy and ecology, which resembled initial cellular growth in leaves, stems, and fleshy dicotyledonous fruit.This work was supported by the Federal budget of Russian Federation, Grant to support for the creation and development of a World-Class Scientific Center Agrotechnologies for the Future, Project No. 075-15-2022-322 date 22.04.2022 and accordance with Institutional Research Project No. 122042700002-6 at the Unique Scientific Installation Fund Greenhouse.
