A multiple regression equation is obtained, where the predictors are the yield of spring wheat, and the predictors are the average precipitation for may-June, the average amount of precipitation for the growing season (may-August), precipitation for the year and June, air temperature for June, and the average air temperature for the period may-June. Correlations were found between individual meteorological parameters, as well as between the actual yield and meteorological indicators. It is shown that meteorological conditions (precipitation and air temperature) of the spring-summer period (may-June) have the greatest impact on the crop. Analysis of the regression equations showed that there is a satisfactory agreement between the actual and calculated data on spring wheat yield, which allows using them for predictive purposes.","PeriodicalId":131329,"journal":{"name":"Bulletin of Udmurt University.

They include observations of the rate of destruction and retreat of the walls of landslide-scree slopes, cut by abrasion, and processes that develop on the emerging shallows. For the first time, the processes of slow mass displacement of material entering the shallows due to the destruction of the banks were established and quantified within the shallow coastal waters. The main morphological types of coastal geomorphosystems are identified and the rates of re-formation are determined for their surface and underwater parts. It is noted that the most productive processes in relation to the flow of loose material into the reservoir bowl are the processes of shedding. Accordingly, weathering, as a source of loose material formation, acquires the importance of the most important shore-forming factor in the surface part of coastal geomorphosystems in the reservoir conditions. Among the most important lithodynamic flows of underwater sections of the coastal zone, the underwater \"creep\" is singled out. It was found that the layer of loose sediment lining the bench with a layer of 20-25 cm by the beginning of ice formation completely slides in the drying zone at a distance of 15-20 meters by the beginning of spring water discharge. Mass displacement of fine-grained earth occurs in the summer, but the slid material is actively replenished with abrasive products in the summer. Banks are destroyed by parallel retreat of the underwater and surface parts of the coast. At present, the rate of coastal destruction often increases rather than decreases, which makes it necessary to review some theoretical provisions concerning the laws of coastal development and forecast estimates. The results obtained can be used to estimate the rate of siltation of the reservoir basin.","PeriodicalId":131329,"journal":{"name":"Bulletin of Udmurt University. Series Biology.

The method of asynchronous correlation analysis with lag from 0 to 70 years revealed a statistically significant relationship between long-term temperature fluctuations and the number of sunspots. The best positive relationship was found with a 65-year delay in temperature fluctuations relative to changes in solar activity. It is assumed that, with cyclical changes in solar activity, induced quasi-zonal electric currents arise in the World Ocean that can create changes in water temperature in the ocean depths, mainly in the area of the Antarctic Circumpolar Current. Cyclical temperature changes appear on the surface of the Southern Ocean with a delay of ~ 30 years. Then, through the system of currents of the Broker's global oceanic conveyor, temperature perturbations are transferred from the Southern Ocean to the North Atlantic and affect the air temperature in Europe with a delay of another 30-36 years.","PeriodicalId":131329,"journal":{"name":"Bulletin of Udmurt University.

Different hydrothermal regimes of ecotopes underlie the distribution of life forms of vascular plants. The spatial heterogeneity of floristic diversity is largely due to a set of species of grassy life forms. Woody life forms are not numerous, but play a significant role in the structure of the vegetation cover. The species richness of communities naturally decreases during the transition from larch forests and woodlands to mountain tundras with single trees. At the same time, communities are largely similar in species composition, and the set of life forms is preserved, but the composition and ratio of different types of life forms change. The transition from smooth variability in the composition and ratio of life forms to markedly increased variability as a result of natural environmental factors is clearly visible, which is correspondingly reflected in a decrease in indicators of species similarity of communities.","PeriodicalId":131329,"journal":{"name":"Bulletin of Udmurt University.
