Cedrus deodara is one of the most useful tree species. Almost every part of the plant has good properties. Cedrus deodara has been an important tree due to its Ethnobotanical uses, Traditional uses, Phytochemistry and Pharmacology. From last decade, there has been a great progress in the medicinal perspectives of Deodara. Deodara has its utility in folklore medicines. Phytochemistry studies showed the presence of various useful compounds in the Deodara tree. Also, the oil of Cedrus deodara has a characteristic fragrance. C. deodara is also having traditional and ethnobotanical uses. Since Vedic period, various parts of this plant are being used for medicinal purposes.It is also believed that various respiratory diseases can be just cured by just sitting under this tree. In present, Deodara is seen as an important tree in point of view of research. It has its applications in Timber too [1]. This paper is focussed on the traditional and medicinal aspects of Cedrus deodara.

Ethnopharmacological Relevance: Borago L., (family Boraginaceae) is a small genus of annual or perennial herbs with branched flowers, which is commonly found in the Mediterranean region. Some species known as Gavzabȃn in Asian and some African countries are traditionally used instead of Borago. Aims of the Review: The purpose of this study was to provide comprehensive scientific information on phytochemistry, traditional uses and pharmacological activities of Borago species to provide an insight into further research on the therapeutic potential of these plants. In many studies, it has been shown that different parts of Borago species, including leaves, flowers, seeds, roots and aerial parts possess numerous ethnobotanical values. Materials and Methods: All ethnobotanical, phytochemical, pharmacological, and clinical data were collected from online journals, magazines and books (all of which were published in English, Arabic, and Persian) from 1968 to 2018. Electronic databases such as Google, Google Scholar, PubMed, Science Direct, Researchgate, and other online collections were used. Results: The phytochemical studies on five species showed a wide range of phytochemicals belonging to different classes of secondary metabolites. From a pharmacological point of view, different extracts and fractions, essential oils, and pure compounds isolated from various Borago species have shown diverse activities in in vitro, in vivo, and clinical studies confirming various traditional uses of Borago genus. Conclusions: Considering the reported activities of the Borago genus both in traditional and modern medicine, further studies on biological aspects and identification of the mechanism of action for drug discovery are highly required.

In Nepal Begonia L. is represented by 22 species of which ten species are reported in having ethnobotanical value. The 22 Begonia species including the seven endemic species largely belong to 2 sections, Begonia sect. Diploclinium and Begonia sect. Platycentrum. Most Begonia species occur in eastern and central region, and few species in western region. In this paper, ten species of Begonia mostly used as food, ornamental purpose and for medicine in most parts of Nepal is described. Except for Begonia picta, the ethnobotanical uses of other Nepalese Begonia species have not been reported in any previous literature from Nepal.J. Nat. Hist. Mus. Vol. 27, 2013: 25-34

Abstract Root vulnerability to cavitation is challenging to measure and under-represented in current datasets. This gap limits the precision of models used to predict plant responses to drought because roots comprise the critical interface between plant and soil. In this study, we measured vulnerability to drought-induced cavitation in woody roots and stems of five tree species (Acacia aneura, Cedrus deodara, Eucalyptus crebra, Eucalytus saligna, and Quercus palustris) with a wide range of xylem anatomies. X-ray microtomography was used to visualize the accumulation of xylem embolism in stems and roots of intact plants that were naturally dehydrated to varying levels of water stress. Vulnerability to cavitation, defined as the water potential causing a 50% loss of hydraulic function (P50), varied broadly among the species (–4.51 MPa to –11.93 MPa in stems and –3.13 MPa to –9.64 MPa in roots). The P50 of roots and stems was significantly related across species, with species that had more vulnerable stems also having more vulnerable roots. While there was strong convergence in root and stem vulnerability to cavitation, the P50 of roots was significantly higher than the P50 of stems in three species. However, the difference in root and stem vulnerability for these species was small; between 1% and 31% of stem P50. Thus, while some differences existed between organs, roots were not dramatically more vulnerable to embolism than stems, and the differences observed were less than those reported in previous studies. Further study is required to evaluate the vulnerability across root orders and to extend these conclusions to a greater number of species and xylem functional types.

Presented paper summarizes the knowledge concerning the cultivation of Douglas-fir (Pseudotsuga menziesii /Mirb./ Franco), its production as well as its non-production forest functions in the conditions of the Czech Republic/Middle Europe. It analyzes the research outcomes from the point of view of volume and value production in comparison with domestic tree species, from the point of view of the soil effects and effects on the ground vegetation diversity, and from point of view of stability and cultivation in the last period. Main aim is represented by the comparison with the Norway spruce, which can be with advantages replaced by this species, with favourable impact on amount and value of the timber production, on the soil and biodiversity status of the ground vegetation. The Norway spruce is heavily affected and endangered by the coming or supposed climatic changes. Also the stability of forest stands can be supported considerably replacing Norway spruce by Douglas-fir. This species can represent suitable alternative to the Norway spruce in lower and middle altitudes and it can contribute highly to the competitiveness not only of the Czech, but European forestry too, increasing stability and production, decreasing the negative effects of the tree species changes in the past.

AbstractAlthough harvestmen (Opiliones) are among the best studied groups of arachnids in Europe from the faunistic point of view, there is still lack of available information on ecological requirements of the particular species. Habitat preferences that determine the distribution of species are largely determined by the habitat structure and microclimate. Besides other factors, these characteristics of habitats are also influenced by the nature of the vegetation. Therefore, our study dealt with the influence of tree species on harvestmen communities. We conducted the research on nine sites in the Borová hora arboretum (Zvolen town, Central Slovakia). Each studied site represents a monoculture of one of nine tree species. On each site also some attributes of soil and leaf litter (pH, conductivity, content of H, C, N and P) were evaluated. Harvestmen were collected by pitfall trapping during vegetation periods in 2008–2012. In total, 2515 individuals of 17 species and 3 families were obtained. Significant differences were revealed between the compared forest stands in terms of total epigeic activity and species richness of harvestmen. The hierarchical cluster analysis divided harvestmen communities into two main clusters (except community of the site with European hornbeam). The first one represented four sites with relatively lower canopy (< 50%) and with the higher number of captured individuals, the second cluster grouped four sites with higher canopy (> 50%) and with the lower number of captured individuals. The results of research confirmed statistically significant relationships between the litter conductivity and equitability and between the litter pH and equitability of harvestmen communities.

Calculation Procedures

Both we and the children we now teach must come to terms over the next few decades with inventions that have potential for great progress or great harm. Everyone must live with these dilemmas but we in mathematics education are thrust to the forefront of them by four additional circumstances. First, technological advances require that at least a few tens of thousands of people be very well educated in mathematics. (Here and elsewhere I intend “mathematics” to include “statistics and computers.”) Second, middle-level mathematical capabilities are needed in the everyday occupations of millions more people now than would have been the case only a few decades ago. Third, much of the information served up by our modern world can only be properly examined by people with sound numerical intuition—comfort with things mathematical has become a condition of intelligent citizenship for millions of people. Fourth, universal availability in developed countries of very cheap calculators has suddenly and fundamentally altered what might be meant by numeracy, since essentially no one outside of school now chooses to use the calculation procedures which dominate elementary school mathematics instruction.

Vegetation phenology is considered an important biological indicator in understanding the behaviour of ecosystems and how it responds to environmental cues. The aim of this paper is to provide information on the variability of phenological behaviours based on discriminant analysis using the R software package with the following libraries: ggplot2, heplots, candisc, MASS, car, and klaR. Three phenological phases were analysed with eight wild fruit tree species from a forest ecosystem in the southwestern part of Romania (44°05′19.5” N 23°54′03.5” E). It was found that there is a large and very large variability for the “bud burst” phenophase, medium and low for “full flowering”, and reduced for the “all petals fallen” phenophase. For the analyzed data, the discriminant analysis model has high accuracy (accuracy: 0.9583; 95% CI: (0.7888, 0.9989). Partition plots show the results of “full flowering” and “all petals fallen” as a function of the “bud burst” of pockmarks when separated into eight clusters and eight clusters of “full flowering” as a function of “all petals fallen”. The differences observed, from a phenological point of view, are not only due to the different cold requirements of these species but also to the temperatures during the spring.
