Comparison of Forest Species- Diversity and Composition Inside and Outside of the Holedná Game Reserve (The City of Brno, Czech Republic)

Abstract The impact of ungulates on the forest vegetation has far-reaching consequences: it decreases species diversity and the production of biomass, causes soil dehydration, erosion and eutrophication the entire forest community. The article addresses the influence of fallow deer and mouflon on the forest vegetation in the Holedná game reserve (western border of the city of Brno, South Moravia, Czech Republic) and compares differences with the forests adjacent to the game reserve. Sixty localities were distributed randomly and phytosociological relevés subsequently recorded there according to the age of the stands inside and outside of the game reserve. The differences in floristic composition were compared for trees, shrubs and herbs, the herb layer species number, the diversity indices and the values of Ellenberg indicators. In the game reserve, a significant difference was found in the coverage of the herb and shrub layer, which was significantly lower than outside the territory. Furthermore, the increased amount of nitrophilous, heliophytes and ruderal herb species inside the game reserve exhibited affiliation to the interior of game reserve. Besides, young trees and woody sapling were less abundant or even missing inside of game reserve. By contrast, the frequency of typical species of oak-hornbeam forests was higher outside game reserve. Due to the higher number of animals and consequent disturbances, nitrophilous plant species dominate in the herb layer of the game reserve, while forest species are more often represented outside it.

The present study has an exploratory nature and aims to analyze the perception of managers on the efficiency, access importance, use as a communication tool, benefits and difficulties of Internet use in Brazilian hotels and also its effects according to the facilities rank and property size plus managers’ age and experience time. It has been used as a questionnaire to collect data from the managers of 35 hotels in the city of Natal, RN, Brazil. By using analysis of variance (ANOVA) and the Tukey test, results showed that there is almost no significant difference on the perception of managers on the impact of Internet use in hotels. However, those variables that were different show that for younger and less experienced managers and luxurious hotels with more than 50 rooms, there is a more favorable perception on the impacts of the Internet.

Introduction“Viaje del Parnaso” is a volunteering project developed at the Day Center Aranjuez2 (CD2) for helping adults with SMI to get a satisfactory and responsible occupation through their implication in a volunteering work in the community, while involved in the maintenance of a green area in the city of Aranjuez.Objectives/aimsThe aim of this study was to evaluate the impact of the project on the volunteers’ lives in terms of personal growth and environment conservation and compare its results with non-volunteers also attended at the CD2.MethodsThe project was carried once a week during 45 weeks. 11 volunteers participated on the project, plus 5 non-volunteers were considered as cuasi-control group. The instruments applied were an item on “environment conservation” and 2 subscale items of “Personal Growth” from the Ryff Scales of psychological well-being. Measures were applied at baseline, 6 and 12 months after.ResultsSignificant differences were found on the environment conservation item between volunteers at baseline and 6 months after (P < 0.05). Results also revealed a significant difference (P < 0.05) between volunteers and non-volunteers at both variables (“environment conservation” and “Personal Growth”) in baseline and 6 months after treatment.ConclusionsThe data from this study suggest that a volunteering program seems to be an effective intervention for bringing about improvements in well-being of people with SMI, and also for increasing their environmental awareness. These improvements may also help to change the stigma of SMI reinforcing mental health patient's contributions to society.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Local extinction of native Atlantic Forest flora species occurs mainly due to habitat fragmentation. Reforestation and natural regeneration can mitigate these factors. The present study attempts to understand whether floristic composition and dispersal processes are being reestablished in an area of lowland Atlantic Forest, eight years after its reforestation. The study area was an old pasture set between two urban fragments in the city of Recife that was reforested in 2011. Melastomataceae species were collected in this area and the morphology of their fruits was compared with the species of the family recorded in the adjacent fragments. Miconia prasina, M. albicans, M. affinis, Clidemia hirta, and C. capitellata have been found in the reforested area. Although there are species with larger fruits in the adjacent fragments, there was no statistically significant difference between the means of the two areas. The fruit morphology indicates that the species found in the area are dispersed by birds and small mammals. It is possible to conclude that the reforested area already presents the expected ecological processes for a corridor between two fragments. Thus, the two adjacent areas serve as vectors for the colonization of native Atlantic Forest species in the reforested area.

Shannon’S Diversity Index

Background. The article presents the results of the research on bees (Hymenoptera, Apoidea) that occur in the city of Lviv. Bees are one of the most important pollinators of many species of angiosperm plants. Research on species diversity of bees is very important not only on the wild nature territories, but also on the urbanized areas. Cities have a significant impact on bee species diversity, their biology and conservation. A comprehensive study of all Apoidea on the whole territory of the city of Lviv has been conducted for the first time in more than 80 years and we hope that the presented materials will lay the foundation for further more detailed studies in this area. Materials and Methods. Lviv is the largest city in Western Ukraine located on the eastern edge of the Roztochia Upland. The material was collected during the warm period of 2017–2019. The Moericke (yellow) pan traps and the entomological nets were used. Besides, we collected dead bees (killed by traffic) along the roads. W have analyzed the entomological collection of the Zoological Museum of the Ivan Franko National University [ZMD] (Lviv). The stereoscopic microscope and a variety of specialized keys for bee species identification were used. We used the Shannon’s diversity index to assess species diversity. We also calculated the Shannon evenness measure to facilitate the interpretation of the results. Results. We analyzed 960 specimens of bees that belong to 106 species, 25 genera and 6 families. The current (second) part of our study deals with review of the Colletidae (3 species), Halictidae (22 species), Megachilidae (11 species) and Melittidae (5 species) families. Species diversity of the bees from Andrenidae and Apidae families was analyzed in previous (first) the part of our research [27]. Conclusions. All species from the six families are native for the territory of Europe. The majority of them are polylectic (≈ 61 %), while the number of oligolectic species (≈ 23 %), or species that do not need to collect pollen (≈ 16 %) is much smaller. The Shannon’s diversity index is approx. 3.718 and the Shannon evenness measure is 0.799 (the honeybee Apis mellifera was excluded in both calculations). Analysis of the impact of urbanization and various environmental factors on the species diversity of bees requires further detailed studies. Keywords: bees, species diversity, Lviv, Ukraine

This paper aims to compare the developmental aspects of regional airports in the Czech Republic. Only international airports were included in the selection, namely airports with an IATA code (IATA – International Air Transport Association). The following factors affected the selection of airports: air transport volume and the runway length. All public international airports with scheduled and non-scheduled commercial traffic have been included in the selection, these airports being The Brno – Tuřany Airport (BRQ), Leoš Janáček Airport Ostrava (OSR), Pardubice Airport (PED) and Karlovy Vary Airport (KLV). The list intentionally excludes the Vaclav Havel Airport (PRG), which, being the airport of the capital city, would have excessive impact on the evaluation of the monitored statistical data. In terms of individual airports, the author evaluates the impact of runway parameters, reference field length and the parameters of radio navigation and lighting equipment. Other monitored aspects include the population of the respective cities (or cities where the airport is located), the airport's location relative to the city centre and its transport connection. The last monitored aspect is the impact of competing foreign airports from across the border on the regional airport's development. The aim is to prove or disprove the idea that the airport with best equipment and location (airport with the greatest potential) should exhibit the best performance in terms of the number of passengers throughput, number of movements and the cargo throughput.

AbstractExtensive tall-trunk orchards, an important element of the central European landscape since the Middle Ages, conserve potential for the future regarding their biodiversity, land use policy and agricultural value. For these reasons, extensive tall-trunk orchards are interesting with regard to nature conservation. Once the management of these low-productivity vegetation sites ceases, the habitat is threatened by successive overgrowth by shrub vegetation. Taking abandoned tall-trunk cherry orchards with dry/mesophilous grassland undergrowth in the locality of Kaňk as an example, the degree of colonization of orchards by woody species and differences in the structure of vegetation cover in different periods after abandonment were monitored. The results showed that the cover of cherry trees in orchards abandoned before 1990 was approximately 30% lower than in orchards abandoned after 2000. The cover of the herb layer in orchards abandoned before 1990 was approximately 60% lower than in orchards abandoned after 2000. The species diversity of orchards abandoned before 1990 was statistically significantly lower than that of orchards abandoned after 2000. The total cover of all species in habitat in areas of medieval ore extraction was approximately 50% lower than that in land originally used for farming.

Abstract Background and aimsHigh-intensity grazing in the Mongolian grassland has led to the general deterioration of biodiversity and ecosystem functioning. Although abundant evidence shows that grazing affects the structure and function of grassland ecosystems, research on the impact of precipitation, especially under drought and overgrazing. MethodsWe examined the effects of heavy grazing, moderate grazing and no grazing on plant communities; plant and soil C, N and P contents; and plant and soil C:N:P stoichiometry in the desert grassland in different years with different amounts of precipitation. ResultsThere was no significant difference in the species diversity between the grazing and no grazing treatment, while the no grazing treatment was significantly higher than the heavy grazing treatment. Compared with the amounts in the no grazing and moderate grazing treatments, the N and P contents of the plants in the heavy grazing treatment were the highest, and the N content of the soil increased. There was a positive correlation between precipitation and the N and P contents of plants and the C and N contents of the soil at 0-10 cm and 10-20 cm. ConclusionsOur study suggest that a large amount of precipitation of plant growth will drive changes in the community species diversity. Grazing promoted the flow of N between plants and the soil, especially under heavy grazing. Under grazing stress, plants maintain the potential of compensatory growth, and precipitation in the peak season of plant growth induces rapid growth, suggesting that precipitation is an important factor driving grazing ecosystems.

Related Mortality

Data on the numbers of Pekin ducks transported to slaughterhouses between 2009 and 2014 and the numbers of ducks that died during these transports were recorded in cooperation with the State Veterinary Administration of the Czech Republic. In the monitored period, a total of 12,327,017 ducks were transported, of which 9,545 (0.077%) died. The levels of transport-related mortality over these years varied significantly (P < 0.001); the lowest mortality was observed in 2011 (0.059%) and the highest in 2013 (0.089%). The impact of distance on transport-related mortality in ducks was demonstrated. The lowest transport-related mortality (0.052%) was found for distances shorter than 50 km. It was significantly (P < 0.001) lower than the mortality rates connected with longer journeys. The greatest mortality rates were found for transport distances of 101–200 km (0.105%). In addition, the season of the year significantly affected transport-related mortality in Pekin ducks. The highest death losses were found in the summer (0.090%). Death losses of ducks connected with summer transports were significantly higher (P < 0.001) in comparison with transport-related mortality rates in any other season of the year. The lowest death losses were found in duck transports carried out in the autumn and winter (0.069% and 0.072%, respectively) with no significant difference between those two seasons. Shortening transport distances and maintaining a suitable micro-climate inside transport vehicles especially in the summer are thus two important factors that can contribute to reducing transport-related mortality in Pekin ducks in commercial practice.
