Dynamics Of Populations

Abstract Population-based studies of endangered plant species are key methods for assessment of the status for these plants at any territory. Plant species of the Orchidaceae family are sensitive components in natural ecosystems. That is why determination of the status for their populations can be considered as indicators for the status of natural ecosystem position as a whole. Investigations of three Orchidaceae species populations (Orchis militaris L., Epipactis palustris (L.) Crantz, Malaxis monophyllos (L.) Swartz) were carried out in Central Russia (Republic of Mordovia). Abundance, density, structure and dynamics of populations of these species were studied. Species composition of accompanying flora was established for each rare species. Some morphometrical parameters of individuals for the studied species were measured. Features of ontogenetic spectrum for Orchis militaris and Epipactis palustris populations were shown.

Knowledge on status of peripheral plant populations is important for understanding of species’ adaptation and evolution within their ranges.  There is a lack of data on the status of Silaum silaus (Apiaceae) populations at the periphery of its native range.  One of the most northern native S. silaus populations is situated in the Republic of Mordovia (Central Russia).  This species is considered as Critically Endangered in the region.  Population-based studies of S. silaus have been carried out. Reproductive biology, morphometric parameters of individuals, accompanying flora, seed characteristics (mass, germination rate) were investigated.  Results showed that at the northern limit of the range S. silaus grows in floodplain meadow community previously disturbed by livestock grazing. The area occupied by the population, however, has increased more than 12 fold over the last 15 years. Increasing fruit production together with decreasing fruit mass was established for the studied population compared to populations in the central part of its native range.  In addition, germination rate was very low (2.3–16.7 % depending on edaphic conditions).  Additional studies of S. silaus populations are needed in saline steppes of the closely located territories where it occurs as one of the dominant species in the plant community.

This article presents the results of a study of forest territories of the Yanaul forestry of the Republic of Bashkortostan for 2019. Of particular interest is the study of largeleaved Linden formations in the North of the Republic, since the forested lands of this region have long had the status of operational territories-they were subject to development and all types of use. Over the decades, the ongoing development activities on the forests much damage has been caused to the formation of large leaved lime. Until the 1980s, all types of lime cutting were banned here due to the fact that it is a honey crop. But after the removal of this ban in the Yanaul forestry, plantations were subjected to continuous and selective logging for the purpose of harvesting wood. After 35 years of continuous exploitation of Linden forests in the North of the Republic, they led to a sharp decrease in the natural renewal of the studied woody plant species, led to a large number of mechanical damage to the stand and diseases. At the moment, these activities have been discontinued due to the closure of the leading timber processing plant, which was engaged in harvesting and deep processing of wood, in particular Linden. Therefore, studies of annual changes in sanitary and phytosanitary conditions, as well as analysis of the dynamics of natural renewal of forest-forming species are necessary, which determines the relevance of this work. Continuous deforestation and lack of high-quality reforestation measures in the valuable Linden forest have led to severe disruption of the natural ecosystem. As a result of the violation of its integrity, pests entered the Linden tree formation, as well as other existing plantings, and a large number of diseases of woody plants appeared, which a few years ago almost completely destroyed such a unique forest ecosystem. At the time of the study, the aim of the work was to study the phytosanitary condition of wood plants in the Yanaul forest district after the termination of operational activities. The tasks included the proposal of measures for the restoration of valuable forest areas, in particular the large-leaved Linden formation.

Jurassic Sequence

In the present paper we describe and discuss belemnite finds from the basal part of the middle Jurassic sequence at the southwest of the Republic of Tatarstan (Tetyushi district). The belemnites were collected from the outcrops located along a shoreline of the Kuybyshevskoye reservoir (Volga river) between the place Tarkhanovskaya pristan and the former village Dolinovka. These belemnites indicate that the basal part of the Jurassic sequence is Early Bathonian (Ishmae Zone) or, less probable, Middle Bathonian in age. Such dating triggers a critical review for the age of the middle Jurassic sequence in the region. In particular, poorly preserved ammonites previously collected from the same outcrops higher in the succession and interpreted as members of the Late Bajocian subfamily Garantianinae, are in fact Late Bathonian Gowericeratinae. Consequently, Beds with Garantiana nominally the most ancient ammonite-based biostratigraphic unit within the whole Jurassic of European Russia, based on this assemblage, is invalid.

Migration Crisis

In daily communication are often used terms, such as migration, immigrants, refugees, emigrants, asylum seekers and similar, which in principle denote persons living outside the country of origin and their properties. However, there is often a lack of understanding in the perception and distinction between these terms, which in academic practice necessarily requires the determination of the scope and content of those terms. Therefore, we should try to point out the content and scope of concepts that define the status of migrants in the modern world.The paper deals with the basic concepts of migration, as well as the main features of the current migration crisis, with the focus on the consequences of the migrant crisis in the Republic of Serbia and the evinced security implications are described.The aim of the paper is to point out the most important consequences of the migrant crisis in the Republic of Serbia and to assess the possible future implications of the migrant crisis, which is primarily conditioned by the the degree and dynamics of solving problems in the Middle East, political and other decisions and measures of the European Union and neighboring countries.

This study aims to examine the opportunities for Balinese women in the field ofbusiness development after divorce from mixed marriages, prioritizing the principle ofgender responsiveness into awig-awig, the application of the burden of tolerance to102menyama braya, the status of krama istri, and carrying out the obligation to dance at thetemple. Tri Kahyangan is the goal of the gender content in the law of the business beingdeveloped. The research method in this study is sociological jurisprudence, and the typeof research is analytic study of legal materials that adopt women's rights in the businessworld. The binding legal material refers to the Republic of Indonesia State ConstitutionArticle 18 B paragraph (2) and the Traditional Village Awigers which refer to the DecreeNumber 01 / KEP / PSM-3/ MDP / Bali / X / 2010 by the Main Assembly of the PakramanVillage ( MUDP) Bali concerning the division of inheritance of Balinese women withstatus (pradana) has the right to inherit even though they have married and followed herhusband, inheritance in the form of assets can be the main capital for businessdevelopment in the context of business law. The determination of the research subject wascarried out by stratified random sampling. Legal material analysis techniques aredescriptive. The results of the study: Balinese women were given the opportunity to beaccepted as wife's manners based on the pre-marital agreement of the bride, bride'sfamily, and traditional village which contained the provision that in the future if anincident of custom divorce is ready to accept and provide opportunities to carry outroutines such as the wives of their wives in general. The implication of the gender contentin the law is that the consensus reference from the results of the women's traditionalvillage meeting that is the status of widows from mixed marriages is given the opportunityto open business opportunities in the local village area, and is entitled to inheritancegrants in accordance with the provisions adopted by MUDP Bali after obtaining anagreement with the family big through family consultation with the traditional village(dharma pula).

Adventive Plants

In this study, 56 adventive species have been identified in Khakas flora to date. In terms of the introduction method, xenophytes dominate; this group is composed of 44 species, which is 78.6% of all the adventive species under study. The ergasiophyte group consists of 12 species (21.4%). According to the naturalization degree, we identified three groups: epecophytes, agriophytes, and ephemerophytes. The epecophyte group is in the lead and consists of 21 species (37.5%). The agriophytes are represented by 19 invasive species (33.9%). The ephemerophyte group is composed of 16 species (28.6%). Thus, the ratios of the synanthropic-plant groups defined according to the introduction method and naturalization degree indicate that most of these adventive plants have been introduced unintentionally and successfully established themselves on a territory new to them. The adventive fraction of natural ecosystems in Khakas flora contains 20 species included in the report “The Black Book of the Flora of Siberia” [1].

Extensive surveys during the winter months in inland areas of Australia have greatly extended both the range and known hosts of Australia's two pest Helicoverpa species. H. punctigera was the more common species, being collected from c. half of the sites sampled. Here a further 47 plant species in 8 families are recorded as possible host plants; the majority (all except two) are new records of native hosts, and greatly extend the existing lists. H. armigera was less common, being recorded from c. 10% of the 554 sites sampled. This species was reared from 28 species in 10 plant families. Both moth species are recorded for the first time from various native plant species, predominantly in the Asteraceae and Fabaceae. The Goodeniaceae is also added to the host list of both species. Determination of the status of host plants is discussed.

Аim. Determination of resistance of Ukrainian chernozem soil microorganisms to the influence of toxic copper(II). Methods. Content of copper-resistant microorganisms in chernozem was determined by counting colonies on a solid nutrient medium containing Cu(II). Resistance of microorganisms was determined by cultivation in the medium with concentration gradient of Сu2+. Results. Microorganisms resistant to toxic copper(II) by ultrahigh concentrations were shown to be present in chernozem soil. Microorganisms grew in the medium containing up to 500 mg/l Cu2+ (CuSO4 solution) and up to 10000 mg/l Cu2+ (in complex with citrate). Chelation of copper(II) with citrate was found to lead to increase of microbial resistance in 20 times. It was determined that a vanishingly small number of microorganisms resistant to toxic copper by ultrahigh concentrations can exist in a natural ecosystem. The number of viable microorganisms decreases with the increase in the content of Cu2+ that is described by the hyperbolic curve. Conclusions. The proposed methodological approach not only allows to isolate copper-resistant microorganisms from natural ecosystems of all geographic zones of the globe, but also avoid complex genetic transformations in order to obtain perspective genetically modified strains for further application in biotechnologies for purification of industrial wastewater. Keywords: copperresistant microorganisms, chernozem soil of Ukraine, diversified microbial community, environmental biotechnologies.

In South Africa the modern outlook towards time may be said to have started in 1948. Both the two major observatories, The Royal Observatory in Cape Town and the Union Observatory (now known as the Republic Observatory) in Johannesburg had, of course, been involved in the astronomical determination of time almost from their inception, and the Johannesburg Observatory has been responsible for the official time of South Africa since 1908. However the pendulum clocks then in use could not be relied on to provide an accuracy better than about 1/10 second, which was of the same order as that of the astronomical observations. It is doubtful if much use was made of even this limited accuracy outside the two observatories, and although there may – occasionally have been a demand for more accurate time, it was certainly not voiced.
