“…The study of the effects of quantitative and qualitative characteristics of forest stands, as well as the soil across the study sites, showed that conservation management had significant effects on soil erosion variability in both protected and non-protected sites [45,50]. Given that the amount of erosion in the non-protected area was slightly greater compared to the protected area, management measures with no direct interference would not effectively preserve the soil and, therefore, will not support all delivery ecosystem services.…”

Vegetation cover is known as one of the most dominant parameters in soil erosion that can considerably affect soil erosion drivers. This study aimed to assess the effects of vegetation cover on soil conservation in Arasbaran Forests, Iran. A part of Arsbaran forests has been protected for 45 years. The other part has not been under protection during these years. This study was carried out in order to investigate the effects of forest protection management on the changes in the amount of soil erosion and compare it with the non-protection sector. To this end, 66 samples were grouped in the two selected elevation classes. Out of every three sample plots, one plot was randomly selected for collecting soil samples. Landsat 8 images and a Digital Elevation Model were utilized for sample collection via ENVI (Environment for Visualizing Images) and GIS (Geographic Information System), respectively. Then, the Revised Universal Soil Loss Equation (RUSLE) was employed to estimate the annual soil loss in the studied sites. The results showed the annual soil erosion of 9.84 and 10.06 tons per hectare/year for protected and non-protected areas, respectively. Moreover, the average annual soil erosion of 9.95 tons per hectare/year was calculated for the whole Arasbaran Forests. The results of the statistical test revealed no significant difference between protected and non-protected sites in terms of erosion rates (p > 0.05). Based on the findings, despite the non-significant and slightly lower soil loss per unit area in the protected site, there is a notable soil loss throughout the entire non-protected area. It appears necessary to conduct a thorough review of existing conservation laws and to closely monitor their effective implementation. This step is crucial for enhancing the effectiveness of forest conservation management in mitigating soil erosion. The results show that absolute forest protection alone cannot make a big difference in preventing soil erosion. In this regard, there is a need to carry silviculture measures to manage protected forest stands to increase the sustainability of the forest. Obviously, in the case of proper management along with protection, it is possible to have a greater effect in preventing soil erosion.

“…Protected areas are currently considered the main tool for counteracting the biodiversity loss and habitat destruction around the world. Their establishment and maintenance of their functioning contribute to the preservation of species diversity [1,2], the improvement of the environmental status of previously disturbed habitats [3,4], and the counteracting of illegal poaching [5]. On the regional scale, protected areas are recognized as local biodiversity hotspots of plants [6], and animals [7].…”

(1) Background: Protected areas are “hotspots” of biodiversity in many countries. In such areas, ecological systems are preserved in their natural state, which allows them to protect animal populations. In several protected areas, the Coleoptera biodiversity is studied as an integral part of the ecological monitoring of the ecosystem state. This study was aimed to describe the Carabidae fauna in one of the largest protected areas of European Russia, namely National Park “Smolny”. (2) Methods: The study was conducted in April–September 2008, 2009, 2017–2021. A variety of ways was used to collect beetles (by hand, caught in light traps, pitfall traps, and others). Seasonal dynamics of the beetle abundance were studied in various biotopes. Coordinates were fixed for each observation. (3) Results: The dataset contains 1994 occurrences. In total, 32,464 specimens of Carabidae have been studied. The dataset contains information about 131 species of Carabidae beetles. In this study, we have not found two species (Carabus estreicheri and Calathus ambiguus), previously reported in the fauna of National Park “Smolny”. (4) Conclusions: The Carabidae diversity in the National Park “Smolny” is represented by 133 species from 10 subfamilies. Ten species (Carabus cancellatus, Harpalus laevipes, Carabus hortensis, Pterostichus niger, Poecilus versicolor, Pterostichus melanarius, Carabus glabratus, Carabus granulatus, Carabus arvensis baschkiricus, Pterostichus oblongopunctatus) constitute the majority of the Carabidae fauna. Seasonal dynamics are maximal in spring; the number of ground beetles decreases in biotopes by autumn.

Resistance spot welding as the basic method of joining car body elements has been used in the automotive industry for many years. For these connections, it is required to obtain the appropriate diameter of the weld nugget, which results in a high strength and durability of the connection during vehicle operation. The article presents the methodology of testing spot-welded joints using both destructive methods: shearing test of the spot weld and the ultrasonic method. The main goals of the performed tests are (1) to determine the correlation between the mechanical strength of a joint, measured in kN, and the selected parameters of the ultrasonic longitudinal wave with a frequency of 20 MHz propagating in the area of the spot weld and (2) to build and verify the predictive models of the weld nugget quality. The correlation of these parameters allows assessing the strength of the connection with the use of a non-destructive test method. On the basis of the performed analyses, it was determined that there is a strongly positive correlation between the number of reverse echoes and the force necessary to destroy the spot weld (0.41) and the diameter of the weld nugget (0.50). A strong negative correlation was also obtained between the number of echoes and the strength (−0.69) and diameter of the weld nugget (−0.72).
