To study the growth and development of Tagetes patula on substrates of various composition, looking for vermicompost in a closed ground, we studied the biometric indicators and characteristics of the pigment complex (nitrogen balance Nbi, flavonols – Flv and chlorophyll – Ch). In the obtained results, the differences were statistically significant when comparing the median morphometric indices of plants on substrates BK-3a; and BK-2 for both periods of vermicomposting. It was established for substrates f vermicomposting for 90 days that there was a statistically significant difference between (P< 0.05) the compared samples of the Nbi index in the BK-2a; and BK-3a;, in chlorophyll when comparing the control with BK-3a;. It was noted that in vermisubstrates for a period 150 days, statistically significant differences were found in Flv in the BK-2б and BK-3б variants, with the Wilcoxon criterion P = 0.01; control with BK-2б, at P = 0.02. This indicates a significant effect of these substrates on the development of Tagetes patula. In this experiment we failed to prove a similar effect for the remaining soil types (P > 0.05).

The article considers the complex composts role from the wastewater residues and beer pellets on the Esenia fetida vermiculture growth dynamics in closed ground conditions as the Yugra territory sustainable development regional aspect. The substrates used: the soil with a total humus content of 1.83 ± 0.51%, the wastewater residues, the brewer pellet, the plants, the food waste, the paper, the bird droppings, the Tamir microbiological preparation, as well as 50 immature worms, the hybrid Prospector. The experiment lasted 30 days. In each compost variant, there were 7 replicates with the MP and worms, as well as 2 controls without worms: with MP and without it. The complex composts showed a positive trend in the increase in the earthworms number and their total mass. The decrease in the substrate mass after vermicomposting using the Tamir microbiological preparation was observed in all variants. A statistically regular decrease in the substrate mass over time due to the growth of the worms was found. The optimum temperature for the worm’s development is +21 degrees, and the pH values at which a high worms number were observed are in the range from 7.8 to 8.2. Thus, it is possible to use all the complex composts variants. The decomposition process and the growth of the worms positive dynamics were observed everywhere at different rates. The beer pellets use in the raw state is possible when adding 10-25% of the compostable substrate total mass with the organic components that have sorption capacity.

Targeted studies of bats in Khanty-Mansiysk Autonomous Okrug-Yugra revealed six species of bats. Animals of this group are spread throughout the region not-evenly, the populations are rarer. Low reproductive capacity and the number associated with living on the border of habitats in Yugra contributed to the inclusion of all species of bats in the regional Red Book. In this article, along with known data, the authors present modern information on the distribution of bats in the territory of the Khanty-Mansiysk Autonomous Okrug. Possible causes of local distribution of species are discussed. The largest species diversity is characteristic of the southern and southwestern part of the region, which is due to the proximity of possible winter sites in the caves of the Northern Ural. In the central and northern part of Yugra there are only ecologically flexible species - the Northern bat and Parti-colored bat.

In the local populations of moor frogs in Surgut city, 30 types of morphological anomalies were discovered. The quantity and frequency of anomalies were high in industrial and multistoried areas of the city. Individual subjects could have 1 to 4 different anomalies. The paper reveals that major variations in anomalies occurs in industrial and multistoried areas of the city.

The between-population and sexual differences in demographic and postmetamorphic growth characteristics were studied in Rana arvalis from several habitats of Khanty-Mansiiskii Autonomous Okrug–Yugra (KhMAO) with a relatively short (about 3.5 months) activity season. Skeletochronology was used for age determination. The annual size increments and the rates of these increments were determined on the base of back-calculated body length at each age. In three of four populations, a higher average age in females but not significant sexual differences in the average body length were revealed. In both males and females of all studied KhMAO populations, the rate of the annual size increment between the 1st and 2nd wintering was maximal. The rate of the annual size increment between the 2nd and 3rd wintering was kept relatively high. In comparison with R. arvalis populations of Bryansk, Moscow, and Kirov oblasts with a longer activity season (seven, six, and five months, respectively), frogs from KhMAO populations had a relatively small average body length at each age and low population averages of the body length. At the same time, the character of between-age dynamics in the rate of the size increments of KhMAO populations enabled us to reveal the effects of counter-gradient selection not yet mentioned in the literature. These effects represent the maintenance of a relatively high rate of annual increments up to the 5th wintering in R. arvalis from KhMAO populations with a short activity season.
