The study of the world of a person's private being in the external environment has begun from the outer zone, from the border of the mastered and known world. Synthesizing realism allows us to make a number of critical remarks about the methodology of the modern development of theoretical physics, warn physicists against falling into a number of erroneous and dangerous trends. Two counter movements are identified in the zone of interaction of the inner and outer worlds: the penetration of the outer world into the area of the inner, the adaptive influence of external nature on the adaptive development of man and the expansion of man into the nearest natural environment, subordinating his impact on the objective world of his habitat zone. It is investigated in what form a person appears according to the results of his external transformative activity from the position of an external observer. The special role of the field of central forces and the inverse square law in human habitable space is emphasized. The law of egocentric concentration is formulated. The ontological roots of anthropocentrism are clarified. Ethnic features in the anthropocentric picture of the world are noted. Plato's observation about the three most important principles in the private existence of man is confirmed. The methodological principle of multifaceted (polyhedral) monism is opposed to the unbridled cognitive relativism of the postmodern era.

In the forest-steppe area, carnivorous mammals are represented by species of different faunistic assemblages. This circumstance makes the study region a priority since the species of which faunistic assemblages prevail is of interest. Fifteen carnivorous species have been identified in the territory of Mordovia. Among them, the family Mustelidae predominates in terms of the number of species. The species are found in all geoecological districts, but their distribution is uneven. The most notable species in the region are located in coniferous and broad-leaved forests (40%) and species widely distributed in several natural areas (40%). 13% of the total number of noted species belong to the taiga fauna types. The steppe type of fauna is represented by only 7% of the total number of recorded species. For each geoecological region, the fauna features are given, and a list of rare and exciting species is given. The forest-steppe zone to which Mordovia belongs is compared by the fauna of carnivorous mammals with other regions from three typical faunal assemblages.

n one natural area, animals may have different distribution. In some areas they inhabit, and in other areas, they do not inhabit. Scientists have been working on this issue for a long time. In this study reports that the species composition and distribution of species varies depending on geoecological districts. Twenty-eight rodent species have been recorded in the territory of Mordovia. The largest number of species in the region belongs to those living in coniferous and broad-leaved forests (42.9%). In the second place in terms of representation are species widely distributed in several natural areas (28.5%). They are slightly inferior to the types of steppe fauna (25%). The taiga type of fauna is represented by only 3.6% of the total number of registered species. For each geoecological district, the features of the rodent fauna are given and rare species are identified. The forest-steppe region of Mordovia is compared in rodent fauna with other regions of Russia with different typical faunal assemblages.

A key term in ecology is 'ecosystem'. Examples of bad definition of ecosystem: These are two definitions of ecosystem that can be found in Internet: 1. "a system formed by the interaction of a community of organisms with their physical environment" (see: wordnetweb.princeton.edu/perl/webwn) The drawbacks of this definition: another term is used , namely, 'community'; why only physical environment is mentioned? if you mention 'physical', you are to mention 'chemical' one as well... 2. "An ecosystem is a complex set of relationships among the living resources, habitats, and residents of an area. It includes plants, trees, animals, fish, birds, microrganisms, water, soil, and people". http://forest.mtu.edu/kidscorner/ecosystems/definition.html The drawbacks of this definition: another term is used , namely, 'habitats'; why only 'living resources' are mentioned? if you mention 'living resources' , you are to mention non-living as well... ; it is wrong to list 'animals, fish, birds, ' (as 'fish' and 'bird' are part of the general term 'animals'); by the same token, it is wrong to list 'plants, trees,...' (as 'trees' are part of the general term 'plants') . That is why it is important that an attempt was made to give a better definition. An example of such attempt see: http://blog.researchgate.net/masterblog/2220_New_Definition_of_Ecosystem; (in English); http://scipeople.com/publication/99205/; (in Russian); http://scipeople.com/publication/70259/; (in Russian); http://scipeople.com/publication/66938/ (in Russian) Also see the paper: Ostroumov S.A., New definitions of the concepts and terms ecosystem and biogeocenosis. — Doklady Biological Sciences. 2002.

DOI 10.1023/A:1015393924967. http://www.springerlink.com/content/vpg4yu2v3yd6t97b/ In 1935 the term 'ecosystem' was coined by A. Tansley. In the 1940s, another important term, 'biogeocoenosis', was introduced by V. N. Sukachev. Since that time, a lot of new facts have accumulated in ecology. It is necessary to revisit the formulation of the basic concepts and terms in ecology, including the two terms mentioned above. The author proposed some new variants of the definition of the two terms that (1) reflect the modern vision of the basics of ecology; and (2) avoid the vicious circle of using other terms that in turn request their require definitions. The author realizes that the new variants of the terms cannot be ideal and some other variants of the definitions are also possible. Tables: 5 specific features of the proposed definition of ecosystem (Table 1); 8 specific features of the proposed definition of biogeocenosis, and 8 distinctions between the proposed definition and the classical definition by V.N.Sukachev (Table 2).
