The current status of aquatic biological resources and their habitat cross-border section in the Dnieper river within the Smolensk region Russian Federation and the Republic of Belarus

The study presents materials on the status of aquatic biological resources and their habitat in the Dnieper River within the territory of the Russian and the Belarus. In the recent period, there has been hardly any complex fishery research in the upper reach of the river within the boundaries of the Smolensk Region due to the lack of commercial fishing; the same can be applied to the reach of the river within the Vitebsk Region in Belarus. The collection of materials and scientific and research accounting network surveys for monitoring the state of aquatic bioresources were carried out on the Dnieper River as part of the research in 2019 according to a preplanned grid of stations. When fishing for scientific research purposes, 20 net-stops of smooth frame nets were made in the Russian section, and 9 net-stops were made in the Belarusian section. In the Russian section of the Dnieper River, the species composition was 16 species of fish, and in the Belarusian section — 22 species. The main catch in the Russian section is roach 29% and chub 20%, in the Belarusian section bream — from 3 to 46%, roach — from 19 to 63% and gustera — from 1.8 to 33%, in a slightly smaller number of river perch (on average up to 10%). The share value of roach and guster tends to decrease from the upper to the lower areas, bream-on the contrary to increase, the value of perch is approximately equal in all areas. In the size structure of the caught fish species, there is a dynamic with a good reproductive potential.

Conflicts in the environment of Russian political emigration in Switzerland in 1870

Russian political emigration from the beginning of its birth in the first half of the nineteenth century was constantly in search of forms and methods of struggle with royal power in the homeland. Detachment from Russia, the feeling of isolation that was inherent in emigration to the early twentieth century, were an important factor in the ongoing conflicts that took place in its environment. We note the conflicts between the «old» and the «young» emigration in the late 1860’s, between the Marxists and the populists of the 1880’s, between the revolutionary Marxists and the «economists» at the end of the 1890’s. All of these, as a rule, were due to excessive the ambitions of some leaders, the attempt to become the «rulers of ideas» for revolutionary youth, due to significant financial problems. In the list of these and similar conflicts there are events of 1870, when in the environment of political emigration there are two serious confrontations between the leader of anarchists M. Bakunin on the one hand and S. Nechaev or «Russian section of the First International» - on the other. These conflicts significantly influenced the situation in emigration, disorganized it, weakened the ability to fight the tsarist regime. They were accompanied by sharp accusations, searches for compromising materials, attempts to get support from leaders of the world revolutionary movement. The ambitions of young revolutionaries such as S. Nechaev or M. Utin were also connected with the attempt to take the main place among the emigrants, moving to the background of former leaders M. Bakunin, M. Ogarev, P. Lavrov. All this led to split in emigrant colonies, which consisted mainly of student youth. Violent discussions, accusations, boycotts became a hallmark of emigrant life. Basically, all these events took place in Switzerland, which at that time already became the center of not only Russian, but also international political emigration. Conflicts were directed at the political annihilation of the opponents, which subsequently resulted in the arrest and extradition to the Russian government of S. Nechaev in 1872, the cessation of the activities of the Russian Section of the First International and the return of M. Utin to Russia and the cessation of revolutionary activity in general. The positive side of these conflicts was the rallying of emigrants around their leaders, better information on the state of affairs in their environment, the development of new forms and methods of interaction and the strengthening of the role of revolutionaries from Russia itself.

Chapter 4. Morphology: Nouns

<p><span style="font-family: Cambria;"><span style="font-size: medium;">Learning Contemporary Standard Russian, you have struggled with all the exceptions from the rules. Where do the exceptional inflections of words such as время ‘time’, телёнок ‘calf’ and дочь ‘daughter’ come from? Why is путь the only masculine noun in declension III? Why do some masculines such as рог ‘antler’ and глаз ‘eye’ have ‑a, and not ‑ы in the nominative plural? And where do exceptional plural forms such as небеса and чудеса from небо ‘heaven’ and чудо ‘wonder’ come from? This chapter offers answers to these and many other questions.
