Influence of ecological farming on the community structure of epigeic arthropods in crops Triticum aestivum and T. spelta

Soil is an irreplaceable natural resource that enables the production of food and raw materials, forms agricultural and forest landscapes, filters and maintains water, ensures the cycle of substances in the ecosystem and contributes to maintaining biodiversity. Agricultural intensification is one of the most important factors for biodiversity loss. Spatial dispersion of epigeic arthropods reflects the ecological status of habitats and points to its quality. The aim of our research was to point out the differences in epigeic arthropod diversity in the examined crops Triticum aestivum, T. spelta and the influence of their ecotones on epigeic arthropods. Between the years 2019 to 2021 an investigation using the pitfall trap method recorded 5,232 individuals belonging to 13 taxonomic groups. The crop T. aestivum was represented by 2493 individuals and 13 taxa while in T. spelta we recorded 2739 individuals and 11 taxa. We observed significantly more taxa in the crop T. aestivum than in the crop T. spelta. We also confirmed the ecotone rule only for the T. aestivum crop. We confirmed the significant influence of crops and environmental variables (pH, potassium, phosphorus, nitrogen) on the spatial dispersion of individuals around pitfall traps. On the basis of our results, both ecological farming and their ecotone systems are important for epigeic arthropods and with topical and trophic conditions, which is important for the production of biomass and also affects crop. In any anthropogenic activity, it is important to give priority to less invasive procedures with non-toxic effects on organisms and to use effective technologies in land management

The influence of relief morphometric characteristics upon the occurrence of the species Cordulegaster bidentata in the particular conditions of the Western Carpathians

The study concerns a monitoring survey of Cordulegaster bidentata Selys, 1843 (Odonata, Cordulegastridae), which is considered near threatened in the European Red List of Dragonflies, in order to show its habitat preferences and clarify the influence of slope and orientation of slopes on the occurrence of the species. Investigations of water habitats were carried out during the period from 2019 to 2020 in the Kysuce Region in northwest Slovakia. The protocol consists of looking for larvae and characterizing larval micro-habitat of C. bidentata so as to show their habitat preferences and clarify the influence of slope and orientation of slopes on the occurrence of the species. We sampled 32 watercourses (epicrenal, hypocrenal, rheocren, heleocren, epirhithral, metarhithral) at altitudes 420–950 m above sea level. A total of 79 larvae and 10 imagines (7♂ 3♀) of C. bidentata were found at 12 streams. In the present study, C. bidentata clearly preferred first-order stream sections, the slopes were steep and the proportion of small sediment grain sizes was high. The results show that the number of C. bidentata larvae grew with the increasing percentage of forests around streams. We also confirmed the trend for the number of C. bidentata larvae to increase with increasing values of slope and altitude of watercourses. Most of the individuals were recorded at the south and southwest oriented streams; we did not record larvae on the north and northwest oriented slopes. We assume that more suitable conditions for development of population exist in the streams on the south and southwest oriented slopes. The preference for watercourses oriented south and southwest ensures optimal conditions for the development of the population of this dragonfly species. The finding of larvae at the stages of instars shows the permanent occurrence of the species in the Kysuce Region

Assessment of soil quality in agroecosystems based on soil fauna

Soil arthropods respond sensitively to land management practices and correlate with beneficial soil functions. The aim of this research was to determine soil quality using the QBS index in different types of crops and influence of soil variables (pH soil, soil moisture, potassium, phosphorus and nitrogen) on soil arthropods. Between the years 2018 and 2020, we studied different types of crops (Brassica napus, Pisum sativum, Triticum aestivum, T. spelta, Zea mays, Grass mixture and Hordeum vulgare) and recorded 14 taxa. Our results suggest a higher QBS index value in crops grass mixture, Pisum sativum, Triticum aestivum, T. spelta. The EMI value grew with increasing values of soil moisture, soil pH, phosphorus, potassium and nitrogen; indicating the presence of soil arthropods occurring in higher quality soil. Our results suggest that agricultural intensification affects soil arthropods, which are important for the production of biomass, which also affects crop yields

Adolescents' perspectives on traditional, nontraditional, and direct political activities: The role of identity-processing styles and political beliefs

The study examined whether adolescents’ tendency to employ informational, or normative identity-processing style predicts their perceived effectiveness of different political activities. Data were taken from the broader longitudinal study conducted in the Czech Republic, and included reports from 179 participants (Time 1 = age 17; Time 2 = age 19). Path analyses suggested that adolescents who sought information tended to perceive non-traditional political activity (e.g., in civic organizations) as effective, while participants’ normative conformism predicted disbelief in direct activity (e.g., petitions). Perceived effectiveness of traditional activity (e.g., voting) reflected adolescents’ actual political trust rather than their identity-processing styles. These results complement previous findings on the correlates of identity-processing styles and adolescents’ political thinking

Quality Attributes that Matters When Purchasing Milk by Slovak Consumers

Food market has changed dramatically over past decades. Whereas in the past consumers faced problems with food availability and quantity, today they are more concerned with its qualitative side. Milk, Slovak traditional foodstuff, is now experiencing the declining consumer interest. Regarding this, the main aim of the article is to examine the importance and influence of quality attributes on Slovak consumers when purchasing milk. For accomplishing this, a quantitative consumer survey was arranged. Its results showed that to the group of top five most important quality attributes belonged healthiness, freshness, sensory appeals, processing and fat; and a presence of at least two dependencies in relation to age, gender, income and education individually was confirmed. This creates a valuable basis for the value concept development, segmentation, targeting and positioning projection, product strategy modification and innovation and segmentation and marketing mix strategy creation

Citizenship as given or taken? Meanings and practices among majority and minority youth

Present study sheds more light on the conceptualization of citizenship and civic engagement among majority and minority youth. In order to understand the meanings of citizenship, fourteen focus groups were conducted with young people aged 16–26, with both civically engaged and disengaged young ethnic Czechs, Roma, and Ukrainians. Results suggest that young people understand the citizenship as having multiple dimensions (legal and personal, and in terms of rights and responsibilities) and civic engagement as being focused on various aspects. The way people described their position within society was influenced by the social background and mirrored in the views on full citizenship. The research reported in this document was supported by a grant received from the European Commission 7th Framework Programme, FP7-SSH-2007-1, Grant Agreement no: 225282, Processes Influencing Democratic Ownership and Participation (PIDOP), which was awarded to the University of Surrey (UK), University of Liège (Belgium), Masaryk University (Czech Republic), University of Jena (Germany), University of Bologna (Italy), University of Porto (Portugal), Örebro University (Sweden), Ankara University (Turkey) and Queen’s University Belfast (UK).

Rat Spinal Cord Injury Experimental Model

Spinal cord injuries (SCI) with their tragic consequences belong to the most serious pathological conditions. That is why they have stimulated basic research workers, as well as health care practitioners, to search for an effective treatment for decades. Animal experimental models have been essential in these efforts. We have jointly decided to test and standardize one of the spinal cord injury compression models in rats. Twentythree adult female Wistar rats weighing 250-320 g were utilized. Employing general anaesthesia along with a mixture of sevoflurane with O2, 2 rats (sham controls) had their vertebral arch of either Th8 or Th9 vertebra removed (laminectomy). The other 21 experimental rats with similar laminectomies were divided into 3 subgroups (n = 7) which received compression impact forces of 30, 40 or 50 g (subgroups-1, -2, and -3, respectively) applied on their exposed spinal medulla for 15 minutes. All rats were observed for 28 days after the experimental procedure and their motor functions were assessed by the Basso, Beattie, Bresnahan (BBB) test 6 hours, 7, 21 and 28 days after the simulated SCI. All 23 rats survived the surgical procedures. The control rats were without any neurological deficits. There were, in every experimental subgroup, 1 or 2 rats with extreme BBB scores. So the rats with the maximum and minimum BBB values were excluded. Then, the results acquired in the residual 5 rats in each group were averaged and statistically analysed by the Tukey multiple comparisons test. Statistically significant intersubgroup differences were found at all survival times equal to or longer than 7 post SCI days. The goal of the SCI experiment was to generate a reproducible and reliable, submaximal spinal cord trauma model. The statistical analyses demonstrated that this objective was best achieved in the subgroup-2 with the 40 g compression
