AbstractDuring long-term monitoring (more than 20 years) of the hydrologic regime at 20 mountainous sites in the Czech Republic (altitude 600–1400 m a.s.l.; vegetation season April-September; mean air temperature 8–10°C; mean total precipitation 400–700 mm; mean duration of sunshine 1100–1300 hours; mean potential transpiration 200–250 mm) it was found that plant temperature does not rise above about 25°C when plants transpire. According to the ecological optimality theory, the phytocenosis that is able to survive unfavourable conditions and produce the biggest amount of phytomass will prevail at sites occurring in long-term stable natural conditions. Simulation of phytomass productivity based on the optimum temperature for plant growth showed that plants with an optimum leaf temperature of about 25°C can survive the unfavourable conditions and produce the largest amount of phytomass at the site studied in the long-term.

Rational use of natural resources and preservation of environment in good conditions are the basis of stable state of the ecosystem. Mountain soil erosion is the most common process of degradation. Soil protection from erosion is becoming a global problem in the world, and in Uzbekistan, in particular. Natural conditions of the region create a potential danger of soil erosion. The reason for its manifestation is the misuse of land, non-compliance with necessary requirements for soil protection. In most cases, it is due to the location of homesteads and crops on erosion-prone soils that poorly protect soil from erosion, improper cultivation of soils on arable land, unregulated grazing of pastures, and damage to soil protective plantations.

Since decreasing level of knowledge of mathematics is the problem at universities, not only in the Czech Republic, we try to define some reasons for that between our students from different secondary schools. The paper discusses the results of the examinations in mathematics at the university in the Czech Republic. The aim is focused on the differences between the scores of students from different secondary schools. We compare the results of two tests which students have to pass during the semester. In addition, we compare the impact of introducing a new subject called “Math seminar”. This seminar should help students to complete their knowledge of topics from mathematics of secondary schools. We observe the improvement of students who passed the Math seminar. We observe the impact of passing the school-leaving exam from mathematics as well. We would like to consider this as a part of a long-term monitoring of students in this study programme and re-analyze unsuccessful students after they pass the course “Math seminar”.

The article presents the results and analysis of long-term monitoring of the bridge across the Odra River on the D47 freeway in the Czech Republic near Ostrava. Structural system of this bridge is formed by a continuous composite box girder with spans from 49 to 102 m. Total length of the bridge is 402 m. The bridge was equipped by strain gauges and force sensors during the construction. The monitoring has been kept on for 10 years. The measured values are compared with the results of calculations.

The hundred-year dynamics of gamma diversity and butterflies’ abundance have been assessed for the first time in Russia for the Nizhny Novgorod Region. According to analyzed data, we forecast that no significant change in the number of 104 species of butterflies is expected, the number of 33 species in the near future is likely to increase, and the number of 11 species will continue to decline in the near future. A decrease in abundance of 23 steppe and arcto-boreal species is also expected. The reasons for the decrease in the number of species are considered, supported by the long-term monitoring dataset. Extrapolation of our conclusions for Russian regions with similar conditions (Kirov, Ivanovsk, Vladimir, Kostroma, Penza, and Ulyanovsk regions and the Republics of Mari El, Chuvash, and Mordovia), taking into account the natural conditions of these areas, seems applicable and promising.

The Institute of Geodesy and Mine Surveying of the Technical University of Ostrava performs long-term monitoring works and evaluates the effects of undermining in the Ostrava-Karviná coal-field, a major industrial conurbation in the north-east of the Czech Republic. Local extraction of bituminous coal has had significant effects on the surface relief. Actual undermining effects are monitored on selected built objects on a regular basis. Some of them are public buildings, roads, listed historic monuments, and buildings of cultural or historic value. Damage to the buildings, etc. can be eliminated to some extent by prudent planning of extraction works in space and time and by applying appropriate protective measures. Santrauka Čekijos Ostravos technikos universiteto Geodezijos ir kadastro institutas atlieka ilgalaikius stebėsenos darbus ir kalnakasybos įtakos vertinimą Ostravos-Karvinos anglių baseine (Čekijos šiaurės rytų pramonės branduolys). Lokali bituminių anglių gavyba lemia didelę įtaką žemės paviršiaus reljefui. Kalnakasybos įtaka reguliariai stebima stebėjimo objektais pasirinkus tam tikrus statinius. Tai viešieji pastatai, keliai, istoriniai paminklai ir reikšmingi istoriniai ar kultūriniai statiniai. Statinių pažeidimų galima išvengti apdairiai planuojant (erdvės ir laiko požiūriu) kalnakasybos darbus bei taikant tinkamas apsaugos priemones. Резюме Институт геодезии и маркшейдерии Остравского технического университета выполняет долгосроч ные работы по мониторингу и оценке последствий горнодобывающей промышленности в Остравско-Карвинском угольном бассейне, являющимся основным промышленным предприятием в северо-восточной части Чехии. Локальная добыча битумных углей в большой степени влияет на рельеф поверхности земли. Влияние горнодобычи регулярно исследуется на некоторых строениях – общественных зданиях, дорогах, исторических памятниках, важных исторических и культурных сооружениях. Повреждения зданий и сооружений можно предотвратить, если планировать горнодобывающие работы с учетом места, времени, а также предпринимая необходимые меры защиты.
