Domino Effect of Coronavirus in Nigeria. An Overview of the Socioeconomic, Religious and Educational Perspectives

Abinotami Williams Ebuete, Okpoebi Kenneth Berezi, Lucky E. Ndiwari, Standfast Isiya
The human history has recorded that in every 100 years a new pandemic will erupt to rocked control the human race from over population, changing the courses of history and signaling the end of entire civilization. Today the world is at halt and its economic, socio-cultural, religious, political, scientific and technological myth is degenerating amidst the advent of a novel pandemic (COVID-19). This study therefore, investigated the effect of COVID-19 in terms of economic, socio-cultural, educati...

Formation of Forests under Contrast Environmental Conditions in South-Western Pre-Baikal, South-Western Trans-Baikal and North-East Pre-Baikal (Some Aspects of Structure and Dynamics)

Alexander P. Sizykh
Zonal and height belts differentiation of environmental parameters determine forms and types of changes during formation of systems of any natural hierarchy. Under climatic conditions, when shifts of environmental (geographic) zones or height belts as definite environments is possible, there are processes able to result in structural differentiation of the whole biosphere. The problem of fores

Forests Organization on the Base of Ecological-Dynamic Characteristics of Vegetation (Some Methodological Aspects)

Alexander P. Sizykh, Alexey I. Schekhovtsov
Mapping of forest vegetation is considered as an efficient method for obtaining of statistic information, which serves as a base for determination of the character of coenisis use in concrete regions. Different scales and periodicity of vegetation mapping allow to establish the peculiarities of coenisis structure, dynamics and functioning. Physical-geographic conditions pre-determine time intervals of forests taxat

The Structural-Dynamic Organization and Trends of Forests Reconstitution in the South-Western Pre-Baikal (Irkutsk Region, Siberia)

Alexander Sizykh, Alexey Shekhovtsov
At the territories of three key sites with different environmental conditions (coast of Irkutsk Reservoir, the Goloustnaya River basin, surroundings of Gakhany settlement in60 kmnorthward from the urbanized area Ust’-Orda, Irkutsk Region), we performed studies aimed to reveal the structural-dynamic organization and trends of forests reconstitution at the places of burnt areas and of cuttings of different targets. We took into acco

The Vegetation Structure (Background) on the Territory of Planned Coal Mine (Irkutsk Region)

Alexander P. Sizykh
Within investigations for project and establishing of a coal mine, preliminary survey aimed to revealing of modern state of vegetation at the territory of establishing of projected coal mine was performed. The information of the structure of phytocenoses modern state can be a reference position for the assessment of a possible impact of technical activities on the state of phytocenoses around

Ecological-Geobotanical Monitoring of Forest Use (Some Methodological Aspects)

Alexander Sizykh, Alexey Shekhovtsov
Setting of forms and methods for forest use must be based on assessment and forecast characteristics of forests modern state taking into account probable trends of their formation (or reconstitution) on the base of the analysis of modern physical-geographic conditions on a concrete territory. A very efficient method for this can be an ecological mapping monitoring of forest use with outlining of a series of ecological-geobotanic m

Ecotones and Paragenese (Object) as Indicators of Structure-Dynamical Organization of Vegetation on the Background of Climate Dynamics (The Lake Baikal Basine as an Example)

Alexander Sizykh
Usage of methods for determination of long-time trends in the dynamics of vegetation formation on the background of climate changes becomes more important at modern stage of the assessment of natural systems development. Solution of such a task results inevitably in necessity to correct the understanding of existing processes occurring in the vegetation cover. It allows establishing a direction of their development in system of na

Determination of the Degree of Pasture Factor Digression in the Communities of Environment Contact Sites (Some Methodological Approaches)

Alexander P. Sizykh
This paper is concerning the problem of determining of the character of disturbance of plant communities under the influence of the pasture factors. There are methodological approaches for determining of the degrees of the digression of the plant communities based on qualitative and quantitative parameters of the structure of cenoses for different natural zones. However, there are no approaches and techniques for comprehens

The Lesser Antilles, True Laboratories for the Study of Forest Systems the Evolution (from the Inventory of Plant Species to the Dynamics of the Anthropized Landscapes)

P. Joseph, K. Baillard
Despite their small size, the French West Indies are characterised by a large number of environments supporting a surprisingly high floristic, ecosystem and landscape diversity. From the foundation of dwelling groups, beginning in the 17th century to the present day, human activities have resulted in the sharp decline of the forest areas. To some extent, the Caribbean forest has become “insularized”. Originally, these fo

Arealogical and Ecotypological Compositions of the Flora of Plant Communities at Environment Contact Sites (Based on Some Pre-Baikal Sites)

Alexander Sizykh
The study of phytocenoses of transitional environmental conditions in the Pre-Baikal Region enabled to reveal modern tendencies of vegetation development in different Pre-Baikal sites. Such cenoses can serve as a regional model for indication of existing processes and of changes in vegetation structure which occurred under different environmental conditions. It is found out that ecotones and cenoses reflecting the paragenese in ve
