Nowadays, bioecological characteristics of species are the basis for flora and vegetation studying on the different levels. Bioecological characteristics of species is required in process of flora studying on the different levels such as biotopes or phytocenoses, floras of particular areas (floras of ecologically homogeneous habitats), and floras of certain territories. Ramensky scale is the one of first detailed ecological scales on plant species ordination in relation to various environmental factors; it developed in 1938 (Ramensky, 1971). A little later (1941), Pogrebnyak’s scale of forest stands was proposed. Ellenberg’s system developed in 1950 (Ellenberg, 1979) and Tsyganov’s system (Tsyganov, 1975) are best known as the systems of ecological scales on vascular plant species; these systems represent of habitat detection by ecotopic ecomorphs of plant species (phytoindication). Basically, the system proposed by Alexander Lyutsianovich Belgard was the one of first system of plant species that identiified ectomorphs in relation to environmental factors. As early as 1950, Belgard developed the tabulated system of ecomorphs using the Latin ecomorphs abbreviation; he also used the terminology proposed in the late 19th century by Dekandol (1956) and Warming (1903), as well as terminology of other authors. The article analyzes the features of Belgard’s system of ecomorphs on vascular plants. It has certain significance and advantages over other systems of ecomorphs. The use of abbreviated Latin names of ecomorphs in tabular form enables the use shortened form of ones. In the working scheme of Belgard’s system of ecomorphs relation of species to environmental factors are represented in the abbreviated Latin alphabetic version (Belgard, 1950). Combined into table, the ecomorphic analysis of plant species within association (ecological certification of species), biotope or area site (water area) gives an explicit pattern on ecological structure of flora within surveyed community, biotope or landscape, and on environmental conditions. Development and application by Belgrard the cenomorphs as «species’ adaptation to phytocenosis as a whole» were completely new in the development of systems of ecomorphs and, in this connection, different coenomorphs were distinguished. Like any concept, the system of ecomorphs by Belgard has the possibility and necessity to be developed and added. Long-time researches and analysis of literature sources allow to propose a new coenomorph in the context of Belgard’s system of ecomorphs development: silvomargoant (species of forest margin, from the Latin words margo – edge, boundary (Dvoretsky, 1976), margo – margin, ad margins silvarum – along the deciduous forest margins). As an example of ecomorphic characterization of species according to the system of ecomorphs by Belgard (when the abbreviated Latin ecomorph names are used in tabular form and the proposed cenomorph is used), it was given the part of the table on vascular plants ecomorphs in the National Nature Park «Orelsky» (Baranovsky et al). The Belgard’s system of ecomorphs is particularly convenient and can be successfully applied to data processing in the ecological analysis of the flora on wide areas with significant species richness, and the proposed ecomorph will be another necessary element in the Belgard’s system of ecomorphs.

Makoto (まこと, lit.: truth, genuineness, reality, “realness”) is an element of the conceptual apparatus of the traditional worldview of the Japanese. In Japan, it is generally accepted that makoto is a philosophical and aesthetic concept that underlies Japanese spirituality, involving among other principles understanding of the order and laws of the truly existing Universum (shinrabansho̅; 森羅万象) and the universal interconnectedness of things (bambutsu ittai; 万物一体), the desire to understand the true essence of everything that person meets in life, and, unlike other spiritual values, is purely Shinto in origin. After getting acquainted with the Chinese hieroglyphic writing three Chinese characters were borrowed for the word makoto. Each of these characters means truthfulness, genuineness, but has its own distinctive nuances: 真 means truth, authenticity, truthfulness, 実 signifies truth, reality, essence, content, and 誠 again means truthfulness, sincerity, and truth. Makoto (“true words”) and makoto (“true deeds”) imply the highest degree of sincerity of words and honesty, correctness of thoughts, actions, and deeds. The relationship “true words — true deeds” can be seen as one of the driving factors of moral obligation, prompting everyone in their field, as well as in relations between people, to strive to be real. This desire contributed to the formation of a heightened sense of duty and responsibility among the Japanese, which became a hallmark of their character. However, makoto has not only ethical connotation, but aesthetic one as well, and can be considered as the basis on which were formed the concept of mono no aware (もののあ われ、 物の哀れ) and the aesthetic ideal of the same name, that became the first link in the chain of japanese perceptions of beauty. Each link in this chain is an expression of a new facet of makoto, which was revealed as a result of certain elements of the worldview that came to the fore in the historical era.

A  multi-layer model (FORUG) was developed, to simulate the canopy  photosynthesis of a mixed deciduous forest during the growing season.  Measured photosynthesis parameters, for beech (Fagus  sylvatica), oak (Quercus  robur) and ash (Fraxinus  excelsior), were used as input to the model. This  information at the leaf level is then scaled up to the level of the canopy,  taking into account the radiation profiles (diffuse and direct PAR) in the  canopy, the vertical LAI distribution, the evolution of the LAI and the  photosynthesis parameters during the growing season, and the temperature  dependence of the latter parameters.
