Abstract At present, the inventory lists of the Myriapoda of many geographical areas in Bulgaria and the comparative analyzes of the similarity between such local faunas are scarce or completely missing. The present paper presents the results of the comparative analysis of α- and β-diversity of the myriapoda communities in natural habitats in two regions in Northeastern Bulgaria – the Shumen Plateau and the Madara Plateau. The compared habitats in these plateaus have similar geographical, soil and climatic conditions, and similar species composition of plant formations. The analysis of the structure of the myriapoda communities included estimation of species diversity by determining the Shannon-Wiever index (H’) and the Berger-Parker index (d). The degree of similarity between the species composition of the communities was analyzed by the Czekanowski-Dice-Sörensen, Jaccard, Bray-Curtis, Horn, Morisita-Horn indices and the corrected Chao-Sörensen and Chao-Jaccard indices. The species diversity of the millipede community in the Shumen Plateau is much greater than that of the Madara Plateau, while the diversity of the centipede communities in the two plateaus does not differ significantly. In both classes the greatest species diversity is registered in deciduous and mixed deciduous-coniferous forests. Chao-Sörensen and Chao-Jaccard indices of similarity for the myriapod communities in these habitats are the highest, approaching 1, in contrast to the other sites where the registered species composition of the centipedes is smaller and the degree of similarity is about 0.6.
目前,保加利亚许多地理区域的多足目动物的清查清单和这些地方动物之间的相似性比较分析很少或完全缺失。本文报道了保加利亚东北部舒门高原和马达拉高原自然生境多足类动物群落α-和β-多样性的比较分析结果。这些高原的比较生境具有相似的地理、土壤和气候条件,以及相似的植物结构物种组成。多目动物群落结构分析包括通过确定Shannon-Wiever指数(H’)和Berger-Parker指数(d)估算物种多样性,并通过Czekanowski-Dice-Sörensen、Jaccard、bry - curtis、Horn、Morisita-Horn指数和修正后的Chao-Sörensen和Chao-Jaccard指数分析群落物种组成的相似度。蜀门高原的千足虫群落多样性远大于马达拉高原,而两高原的蜈蚣群落多样性差异不显著。在这两个类别中,物种多样性最大的是落叶和落叶针叶林混交林。该生境多足类动物群落的相似指数Chao-Sörensen和Chao-Jaccard最高,接近1,而其他地点蜈蚣类物种组成较少,相似度约为0.6。

Abstract Citizen science plays an important role in the early detection of invasive alien species (IAS). The involvement of young people in initiatives related to citizen science in Bulgaria could contribute to better monitoring of IAS because of mobility and digital skills of those people. Based on a questionnaire survey, key aspects of involvement of young people in citizen science initiatives were analysed. Two groups of respondents, including professionals (with an educational background in biology or with professional activities related to the bioresources) and non-professionals (not connected with bioresources) were asked to make judgments about their own level of knowledge about: (1) IAS issues, (2) the level of awareness of citizen science; (3) the motivation and preferable ways to participate in citizen science; and (4) the most appropriate approaches for IAS awareness raising. A total of 337 young people in the age range of 15-30 years were questioned during the period 2019-2021. The results show that there is no significant difference between the responses of the two groups of respondents to the questionnaire - professionals and non-professionals. In both groups, less than 50% of respondents are aware of issues related to IAS. Less than 40% of respondents indicated the correct definition of citizen science. The leading motivation factor to participate in citizen science initiatives is “caring for nature” followed by “to contribute to nature conservation” and “to learn more about nature”. Most of the respondents are interested in additional information related to IAS and prefer online sources for information.
摘要公民科学在外来入侵物种的早期检测中发挥着重要作用。青年人参与保加利亚公民科学相关倡议有助于更好地监测国际信息系统,因为这些人具有流动性和数字技能。在问卷调查的基础上,分析了青少年参与公民科学活动的关键方面。两组受访者,包括专业人士(具有生物学教育背景或从事与生物资源相关的专业活动)和非专业人士(与生物资源无关),被要求对他们自己的知识水平做出判断:(1)国际会计准则问题;(2)公民科学的意识水平;(3)公民科学参与的动机和途径;(4)提高国际会计准则认识的最适当方法。在2019-2021年期间,共有337名年龄在15-30岁之间的年轻人接受了调查。结果表明,专业人员和非专业人员两组受访者对问卷的回答没有显著差异。在这两个群体中,不到50%的答复者了解与国际会计准则有关的问题。不到40%的受访者指出了公民科学的正确定义。参与公民科学活动的主要动机是“关爱自然”,其次是“为自然保护做出贡献”和“更多地了解自然”。大多数答复者对与国际会计准则有关的其他信息感兴趣,并更喜欢在线信息来源。

Abstract In the present study, we report on new localities in Northeastern Bulgaria, where Elaphe sauromates (Pallas, 1814) was recently detected. We registered five Blotched snakes in the region of Shumen town in the period 2018 - 2022. All of the snakes were adults, three were killed by tools impacts and two of them were road kills. To date, the Blotched snake was registered extremely rare and in rather long intervals (of several decades) in the region of Shumen. Our findings indicate that the species currently inhabits the suburban and urban territories near the villages of Ivanski, Radko Dimitrievo and Konyovets. Two of the locations are new for the 10 km grid-system used for standard monitoring of the biodiversity in Bulgaria.
摘要在本研究中,我们报道了保加利亚东北部的新地点,最近在那里发现了Elaphe sauromates(Pallas,1814)。2018年至2022年期间,我们在蜀门镇地区登记了五条斑点蛇。所有的蛇都是成年人,其中三条是被工具撞击致死的,其中两条是在道路上死亡的。到目前为止,在蜀门地区,斑点蛇被记录为极为罕见,而且间隔相当长(几十年)。我们的发现表明,该物种目前居住在伊万斯基、拉德科·迪米特里沃和Konyovets村附近的郊区和城市地区。其中两个地点是保加利亚用于生物多样性标准监测的10公里网格系统的新地点。

Abstract The present development uses the modeling method described in the literature and proposed a new didactic, functional model of the “chemistry training” system in the application of semiotic approaches: semantic, pragmatic, and syntactic. The main objective of creating such a model is to demonstrate the specific activities of the subjects “teacher” and “pupil” when familiarizing themselves with chemical symbols and their study by students. The added new components in the model “Technology of chemistry training”, “Semiotic information” and the clarified links between them, lead to a complete change in the way the described system works. The developed didactic model makes it easy to guess the relationship between a new learning situation and a result, that is, to predict an unknown process or phenomenon. This model makes it possible to formulate a reasoned hypothesis of the study.
摘要本研究利用文献中描述的建模方法,提出了一种新的“化学训练”系统的教学功能模型,应用符号学方法:语义、语用和句法。创建这样一个模型的主要目的是为了展示主体“老师”和“学生”在熟悉化学符号和学生学习化学符号时的具体活动。在“化学训练技术”、“符号学信息”模型中增加的新组件以及它们之间明确的联系,导致所描述系统工作方式的完全改变。开发的教学模型可以很容易地猜测新的学习情况与结果之间的关系,即预测未知的过程或现象。这个模型使我们有可能对这项研究提出一个合理的假设。

Abstract Experimental work in its milestones is carried out according to the following algorithm: 1. Development of a methodological system, including additional training content in Chemistry and Environmental Protection for the seventh and eighth grades /purposefully selected urological fragments, exercises and summary lessons/, in which the subject of study is chemical symbolism, with the application of semiotic approaches - semantic, pragmatic and syntactic. 2. Conducting a pedagogical experiment to establish the effectiveness of the developed methodological system. 3. Analysis of the results of the pedagogical experiment. The pedagogical experiment is included in the work as the main method of researching the influence of semiotic approaches on the knowledge and skills of students for the proper use of chemical symbols. By conducting a pedagogical experiment, it has been shown that the use of the three semiotic approaches in Chemistry and environmental training facilitates and improves the understanding of the complex meaning of chemical symbols by students. The analysis of the results of the written control works in the seventh and eighth grades shows the existence of significant qualitative differences in students’ knowledge of how to identify chemical objects and the degree of skills formed to reveal the information embedded in chemical symbols.
在其里程碑阶段的实验工作是按照以下算法进行的:发展一套方法系统,包括为七年级和八年级学生提供化学和环境保护方面的额外培训内容/有目的地选择的泌尿学片段、练习和总结课程/,其中研究的主题是化学符号,并应用符号学方法-语义、语用和句法。2. 进行教学实验,以确定所开发的方法系统的有效性。3.教学实验结果分析。教学实验是研究符号学方法对学生正确使用化学符号的知识和技能的影响的主要方法。通过一项教学实验表明,在化学和环境训练中使用三种符号学方法有助于提高学生对化学符号复杂含义的理解。对七年级和八年级书面控制作业结果的分析表明,学生在如何识别化学物体的知识和揭示化学符号中嵌入信息的技能程度上存在显著的质的差异。

Abstract The morphostructural features of the Lilyak Plateau and it’s spatial and morphotectonic relationships with the adjacent parts of the Eastern Pre-Balkan Mountains are examined in the light of modern mobilist ideas. The Lilyak Plateau landform is part of the South Moesian morphostructural zone. This morphostructure borders distinctly to the south with the northern border of the corresponding part of the Fore Hemus morphostructural zone. There are significant morphostructural and morphotectonic differences between these two regional morphostructural units.

Abstract At the modern stage of society’s development, ecology is seen as a complex, interdisciplinary science of the relationships of organisms, society and the environment. Ecology is a science that studies the regularities of the life of organisms in their natural living environment and taking into account the changes made in this environment as a result of human activity. In recent years, the mass media has been constantly talking and writing about ecology, environmental problems related to anthropogenic activity. The person with his activity is heavily polluted and continues to negatively affect the environment at increasing rates. This reckless behavior of humans and the whole of society threatens planet Earth with imminent doom, no less than the use of nuclear weapons. Only from the positions of modern science ecology is it possible to develop issues related to the prudent use of the natural resources of the biosphere and the fight against changes brought about in nature by human activity in the age of the scientific and technical revolution. For this reason, it is necessary to seek information and a solution to the key current problems: What are the main pollutants of the atmosphere, hydrosphere and lithosphere? What is the origin of these substances? How does their impact affect life on Earth? What approaches and methods are needed to prevent environmental pollution?
在社会发展的现代阶段,生态学被视为生物、社会和环境之间关系的一门复杂的跨学科科学。生态学是研究生物在自然生存环境中的生命规律,并考虑到人类活动对这种环境所造成的变化的一门科学。近年来,大众媒体一直在不断地谈论和撰写与人类活动有关的生态、环境问题。这个人的活动被严重污染,并继续以越来越快的速度对环境产生负面影响。人类和整个社会的这种鲁莽行为对地球的威胁不亚于使用核武器。只有从现代科学生态学的立场出发,才有可能发展有关谨慎使用生物圈自然资源和在科技革命时代与人类活动给自然界带来的变化作斗争的问题。因此,有必要寻求信息和解决当前的关键问题:大气、水圈和岩石圈的主要污染物是什么?这些物质的来源是什么?它们是如何影响地球上的生命的?需要哪些途径和方法来防止环境污染?

Abstract The present research focuses on a theoretical study of structural and electronic properties of pure graphene sheet and then adding different number of N2 atoms. The calculations are carried out using the density functional theory (DFT) with hybrid functional B3LYP/6-31G level to investigate the proposed structures. Gauss View 5.0.8 program is used to design the structures of pure and doped graphene sheets. These structures are relaxed by employing the PM6 semi-empirical method with the hybrid functional B3LYPDFT at Gaussian 09 package. The results of the structural properties of the studied graphene sheets showed that good relaxation of the structures, the constant bonds values in the pure graphene sheets in the same ranges of the carbon rings structures. We calculate the total energy, High Occupied Molecular Orbital (HOMO) and Low Unoccupied Molecular Orbital (LUMO) energies and forbidden energy gap.

摘要本研究主要从理论上研究纯石墨烯片的结构和电子性质,然后加入不同数量的N2原子。利用混合泛函B3LYP/6-31G水平的密度泛函理论(DFT)对所提出的结构进行了计算。使用Gauss View 5.0.8程序设计纯石墨烯片和掺杂石墨烯片的结构。利用混合泛函B3LYPDFT在高斯09封装下的PM6半经验方法对这些结构进行了弛缓。所研究的石墨烯片的结构性能结果表明,其结构具有良好的弛豫性,纯石墨烯片的键值恒定在碳环结构的相同范围内。我们计算了总能量、高占据分子轨道(HOMO)和低未占据分子轨道(LUMO)的能量和禁能隙。该掺杂石墨烯片的总能量是各结构结合能的结果,表明这些结构具有弛豫,在纯石墨烯片中加入N2原子对分子总能量的影响是有效的。所有掺杂石墨烯片都有很小的禁能隙,但它的振动取决于每片片的长度和数量以及N2原子在片中的位置。

Abstract Advances in information technology developments have led to improved ways and means of sharing information and good practices in various areas of social development. Providing the necessary tools enables Citizen Sciences (CS) to play an important role in raising awareness and engaging various stakeholders in the prevention of invasive alien species (IAS). In Bulgaria, up until this point, it is poorly developed, and this is largely due to the lack of information to the general public regarding the categorization of species, pathways of introduction and their negative impact. The article examines the possibilities for introduction and use of an advanced ontological model in the area of invasive alien species research, which will aid the process of involving a wide range of stakeholders in various initiatives that will contribute to preventing the introduction and spread of IAS. The researched approach using the advantages of modern information and communication technologies includes acquaintance with the basic concepts in the area of IAS, the processes related to their introduction and spread, as well as taking into account the existing interrelationships, which would provide opportunities for early detection and the rapid eradication of IAS. The developed model will also be applied to measures and policies put in place to change the attitudes of the general public to the problem of IAS.
信息技术发展的进步导致了社会发展各个领域共享信息和良好做法的方式和手段的改进。提供必要的工具使公民科学(CS)能够在提高认识和吸引各利益攸关方参与预防外来入侵物种(IAS)方面发挥重要作用。在保加利亚,到目前为止,它还不发达,这主要是由于缺乏向一般公众提供的关于物种分类、引进途径及其负面影响的信息。本文探讨了在外来入侵物种研究领域引入和使用先进的本体论模型的可能性,这将有助于让广泛的利益相关者参与各种有助于防止外来入侵物种引入和传播的举措。利用现代信息和通信技术的优势所研究的方法包括了解外来入侵控制系统领域的基本概念、与它们的引进和传播有关的过程,以及考虑到现有的相互关系,这将为早期发现和迅速根除外来入侵控制系统提供机会。拟定的模式也将适用于为改变一般公众对《国际会计准则》问题的态度而制订的措施和政策。
