Abstract In connection with the increasing negative impact of invasive alien species on biodiversity and the environment in general, their research, as well as throughout the world, is relevant. The distribution of the Heracleum sosnowskyi and H. mantegazzianum of the secondary range on the example of the Kyiv agglomeration is investigated in the work. In our study we aimed to evaluate the possibility of spontaneous spread of giant hogweeds in the secondary range, adaptation of the species to the new conditions of the environment that favor to control of these species’ expansion and reduce the threat to the urban ecosystems and citizens’ health. We hypothesise that in the secondary range H. sosnowskyi and H. mantegazzianum settle sites with relatively high temperature (Tr), lightening (Lc), and soil moisture conditions similar to that in their natural range. 17 populations and four localities (sites) of H. sosnowskyi and H. mantegazzianum were studied. They were found within forest, meadow, riverine and ruderal plant communities. It is indicated that the advent species fully adapted to the conditions of the environment. The difference by ecological indicators Lc2 and Tm1 is pointed out. According to the results of our research, for the area of Kyiv urban agglomeration the growth of H. sosnowskyi and H. mantegazzianum is indicated in the plants communities of six classes. They spread most in ruderal plant communities of the: Robinietea, Artemisietea, Epilobietea classes. The studied species belong to invasive plant species in Ukraine and are characterized by extremely high effect on the environment and high invasive potential.

The Impact

Internal control plays a role in risk prevention for firms when dealing with serious emergencies, which ensures the sustainable development of firms during a crisis. Based on the rapid outbreak of COVID-19 in China, this paper empirically tests whether internal control alleviates the negative impact of the pandemic on firm performance. Using a sample of Chinese listed firms from the first quarter of 2019 to the third quarter of 2020 and employing the difference-in-difference (DID) method, we find that the firms with a higher quality of internal control achieve better financial performance during the pandemic period; the more serious the pandemic is, the more obvious effect internal control plays. Furthermore, we consider the industry heterogeneity and firm heterogeneity of the risk resistance effect of internal control. In the manufacturing industry, which is a “disaster zone” of the pandemic, and the non-high-tech industry with a low degree of digitization, internal control can play a more important role in firms’ performance. Moreover, for state-owned enterprises, and firms with strong financing constraints, the role of internal control is more prominent. The above results provide empirical evidence for the risk prevention function of internal control and shed new light on the measures for firms to resist emergencies in the future.

The problem of invasion of Sosnowsky hogweed (Heracleum sosnowskyi Manden.) In the Lipovaya Gora SPNA in Perm is considered. A map of distribution of hogweed cenopopulations in the protected area is presented. The results of the influence of the invasion of Sosnovsky hogweed on the biodiversity of vascu-lar plants of some plant communities are presented. It was revealed that the invasion of hogweed into phytocenoses of the Lipovaya Gora protected area leads to a decrease in the biodiversity of vascular plants by about 26.4% (up to 12 plant species). The ways of introduction of cow parsnip into the communities of the protected area are considered. High seed productivity, high projective cover, reaching in some cases 100%, high phytomass, the presence of dormant seeds, rapid development in spring, and high anthropo-genic load on the territory determine the rapid spread of H. sosnowskyi.

Objectives: In this paper, the effects of tobacco on aerobic exercise ability and physical fitness recovery of college students were studied. Methods: University group sports intervention form: traditional characteristic project (basketball) + Taiji soft ball (R&D intervention project). Exercise time: 3 times/week; Activity duration: 30min; Activity intensity: the heart rate is controlled at 120-140 beats/min. All the college students in the experimental group are students who have never smoked, and the college students in the control group are students who have smoked for more than two years. The other conditions are the same. Results: The exercise time and endurance of experimental groups I and II were significantly lower than those of the control group, and the cardiopulmonary function was significantly lower than that of the control group. The indexes of experimental group II changed significantly compared with experimental group I, and the difference was statistically significant. Conclusion: Cigarette smoke can significantly reduce the aerobic exercise ability and anti fatigue ability. The longer the smoking time, the more serious the adverse effects. Therefore, tobacco smoke and nicotine will damage college students’ aerobic exercise ability and have a negative impact on the recovery of physical fitness after exercise.

The distribution of the Sosnovsky hogweed on the southern border of the secondary range in the European part of Russia on the example of the Kursk Region is investigated in the work. It is revealed that Sosnovsky hogweed grows mainly in the western part of the Region in the vicinity of places where it was cultivated in fields in the second half of the twentieth century. The analysis of invader occurrence in anthropogenic and natural ecosystems of the Region revealed patterns of distribution that are characteristic of invasive species at initial stages of their secondary range formation: most of the foci are present in anthropogenic and semi-natural habitats; medium-sized foci predominate (from 100 sq. m. to 1 ha); the greatest number of foci was found in the areas located along roads. The intensive distribution of hogweed in settlements of the Region, especially with pronounced depopulation processes, was revealed. Among natural and semi-natural habitats, most of the foci were found along the banks of reservoirs. In forests, hogweed is found mainly in small groups of vegetative rosettes on the outskirts, with the exception of areas with a strong anthropogenic impact, where multiple foci with generative shoots are formed. At present, hogweed is not found on arable land due to the intensive cultivation of agricultural land in the Region. Plant communities with Heracleum sosnowskyi in the Kursk Region are represented by 4 syntaxons: association Urtico dioicae-Heracleetum sosnowskyi , association Rudbeckio laciniatae - Solidaginetum canadensis variant Heracleum sosnowskyi , association Chelidonio-Aceretum negundi variant Heracleum sosnowskyi , derivative community Heracleum sosnowskyi [ Agropyretalia intermedio-repentis ].

Abstract Sosnowsky’s hogweed (Heracleum sosnowskyi Manden.) mericarps were collected from satellite and stem branch umbels for comparative anatomical investigation. Located near Vilnius city, the habitat of Heracleum sosnowskyi, formerly a natural forest edge has recently been densely occupied by plants of this species. SEM micrographs of abaxial and adaxial surfaces of mericarps obtained from satellite and stem branch umbels of H. sosnowskyi were similar, but morphometrical analysis revealed statistically significant differences in mericarps collected from satellite umbels, which were longer and wider than mericarps from stem branch umbels. The data on longitudinal sections of H. sosnowskyi mericarps clearly showed that embryos of satellite umbels were at later torpedo stage compared to embryos of stem branch umbels, which were at earlier heart stage. These data represent unequal development of the embryos in mericarps from different types of umbels. Such different development can be treated as an adaptation of the invasive plant to occupy the current habitat and survive in the seed bank by allowing the embryo to complete development within a seed and germinate when new conditions permit.

The Difference

The Kammanassie Mountain is a declared mountain catchment area and a Cape mountain zebra Equus zebra zebra population is preserved on the mountain. The high number of springs on the mountain not only provides water for the animal species but also contributes to overall ecosystem functioning. Long-term conservation of viable ecosystems requires a broader understanding of the ecological processes involved. It was therefore decided that a classification, description and mapping of the spring vegetation of the Kammanassie Mountain be undertaken. A TWINSPAN classification, refined by Braun-Blanquet procedures, revealed 11 major plant communities that could be related to geological origin. Habitat factors associated with differences in vegetation include topography, soil type and grazing. Descriptions of the plant communities include diagnostic species as well as prominent and less conspicuous species of the tree, shrub and herbaceous layers. The results also indicate a high species richness compared to similar regions and the difference between plant communities of wet and dry springs. This data is important for long-term monitoring of the spring ecosystems as well as for the compilation of management plans.

One of the main purposes of the 2015 Environmental Protection Law (EPL) of the People's Republic of China is to boost the green innovation of the enterprises. Using heavy-polluting enterprises as examples, this paper uses the Difference-in-difference analysis (DDD) technique to analyze the influence of EPL on the green innovation of enterprises under fiscal decentralization and enterprise heterogeneity. Results show that EPL exerts a negative impact on the green innovation of heavy-polluting enterprises at the national level, as well as those in the central and western areas specifically. The only presence of positive motivation for green innovation is being found in the eastern area, although, the motivation seems to be insignificant. The negative impacts have been lasting in the long run, especially for the low-performance enterprises in the central areas. As for the targeted implementation of EPL in China, local governments should make the best use of financial power under fiscal decentralization. This balanced approach is designed to motivate enterprises in different regions with various performance levels to develop green innovation based on their different weaknesses and strengths.

Background: According to preliminary sequences from 2010, 99.7% of the nucleotide sequences of the modern human and Neanderthal genomes are identical, compared to humans sharing around 98.8% of sequences with the chimpanzee. In contrast, the difference between chimpanzees and modern humans is approximately 1,462 mtDNA base pairs. Materials and Methods: Neanderthal-inherited genetic material is found in all non-African populations and was initially reported to comprise 1 to 4 percent of the genome. This fraction was later refined to 1.5 to 2.1 percent. We had gone through many researches of Neanderthals affected gene flow in humans. Results: It is estimated that 20 percent of Neanderthal DNA currently survives in modern humans. Modern human genes involved in making keratin, a protein constituent of skin, hair, and nails, have especially high levels of introgression. For example, approximately 66% of East Asians contain a POUF23L variant introgressed from Neanderthals, while 70% of Europeans possess an introgressed allele of BNC2. Our finding shines a light on an enzyme called dipeptidyl peptidase-4 (DPP4). Scientists already know the protein allows another coronavirus, which causes Middle Eastern respiratory syndrome (MERS), to bind to and enter human cells. The new analysis, of DPP4 gene variants among COVID-19 patients, suggests the enzyme also provides SARS-CoV-2 with a second door into our cells, along with its usual infection route via the angiotensinconverting enzyme 2 (ACE2) receptor on cell surfaces. Conclusion: Most Europeans, Asians, and Native Americans harbor a handful of genes from Neanderthals, up 1.8% to 2.6% of their DNA. Studies of ancient DNA in Neanderthal fossils have shown the hominin’s DPP4 gene subtly differs from the typical human one. Conclusion: The hominin’s DPP4 gene inherited from Neanderthals plays a major role in Immune System Disorders and Lower Immune response in many diseases. This gene plays a major role in affecting humans with COVID-19 and spreading it through the world. All humans contain this gene from 1 to 4 percent. East Asians, Europeans, Middle and South Americans conveys more, hence; native Africans contain less amounts of hominin’s DPP4 gene. Therefore; East Asians, Europeans, Middle and South Americans are prone to severe COVID-19.
