    Laws and regularities of vocational pedagogy

    The issue under study is relevant, since a modern pedagogical science needs to establish adialectical relationship between the theory and practice of vocational education, becauseresearch in this area as well as in vocational pedagogy has lagged behind the implementedpractical transformations and reforms in recent years.The aim of the paper is to justify the definition of “vocational pedagogy” and to find out whether it is right to use the terms “law” and “regularity” with respect to an independent field of a pedagogical science – vocational pedagogy. The leading approach to studying the above issue is the method of modelling, which enables to reveal the peculiarities of the effect of formulated regularities of vocational pedagogy at the modern stage of society development, to extrapolate their effect on the nearest future of vocational education development and to provide a science-based forecast of its evolution. The results of the research: we revealed the regularities of vocational pedagogy and vocational education, gave a definition of vocational pedagogy as a methodological basis forvocational education, and defined the perspectives of their development. The materials of the paper may be useful for specialists in regulatory, theoretical and practical activities in education for developing and improving educational and professional standards as well as for developing a model for creating future competitive employees in the system of vocational education taking into account the established regularities in the development of the theory and practice of vocational education.Keywords: laws, regularities, creative thinking, vocational education, vocational pedagogy,standards

    Climate and Grazing Effects on the Biomass and Photosynthetic Capacity of Dominant Species in Mongolia Steppe Communities

    Global climate change and grazing are the key factors affecting plant productivity in steppe regions of Mongolia. It is important to separate the impacts of these factors and to assess the contribution of each factor to the biomass of pastoral plants. Here, we studied the grazing and climate impact on biomass and functional traits in three dominant species of Mongolian steppe plant communities: Artemisia frigida Willd., Stipa krylovii Roshev., and Kochia prostrata (L.) Schrad. Both aridity and grazing significantly influenced the biomass of the studied species but the direction and scope of the changes were species-specific. Grazing had no effect on leaf mass per area (LMA), photosynthesis (

    CHANGES IN THE PHOTOSYNTHETIC PIGMENTS CONTENT IN PLANTS ALONG GEOGRAPHICAL GRADIENTS

    The content of photosynthetic pigments (chlorophylls and carotenoids) in plants along latitudinal and altitudinal profiles has been studied. The pigment composition in plant leaves regularly changed with the latitude / altitude. In general, the observed changes concerned the chlorophyll b and carotenoids, which represent the components of light-harvesting complexes. It was assumed that the ratio of pigment forms is one of the important indicators of plant response to environment and predict the latitude and altitude ranges of plant species.Работа выполнена при поддержке РФФИ (грант № 17–29–05019) и программы АААА–А17–117072810011–1

    Leaf traits of C3- and C4-plants indicating climatic adaptation along a latitudinal gradient in Southern Siberia and Mongolia

    Full text link
    Increasing aridity is one of the most important trends of current climate change. Leaf functional traits suggest a substantial basis for assessing the aridity effects on vegetation. However, since plants possess diverse leaf morphology and anatomy due to different evolutionary history of taxa, the effect of aridity can hardly be revealed in a multi-species analysis. We studied leaf functional traits for 317 samples of 193 plant species in steppe and desert communities along a 1600-km latitudinal gradient in Southern Siberia (Transbaikalia, Russia) and Mongolia. We determined morphological leaf traits, quantitative anatomical parameters, physiological parameters, and photosynthetic pigments content. Different relevance of leaf traits for indication of plant response to climate has been demonstrated. The clearest changes in site-mean values along the aridity gradient were shown for leaf thickness, total chloroplast number per leaf area (Nchl/A) and total surface area of chloroplasts (Achl/A) and cells (Ames/A) per leaf area. Unlike leaf size and leaf mass per area, these quantitative mesophyll parameters related to plant photosynthetic capacity were strongly correlated with climate. We found no evidence for a decrease in sizes of mesophyll cells with aridity, but cell volume as well as chloroplast number per cell were linked with plant functional type (PFT). We revealed an increase in Nchl/A and Achl/A in desert-steppe species in comparison to steppe and forest-steppe vegetation types within each PFT of C3-plants (C3-dicot herbs, C3-dicot shrubs, C3-monocots and C3-succulents). C4-plants were generally characterized by low Achl/A and Ames/A, but had higher rate of CO2-transfer through mesophyll and chloroplast surfaces. C3- and C4-plants differed in response to aridity and showed opposite trends in changes of leaf traits along the aridity gradient. We conclude that leaf mesophyll traits contribute to important mechanism of climatic adaptation in different PFTs along a large latitudinal gradient. © 2018 Elsevier GmbHRussian Foundation for Basic Research, RFBR: АААА-А17-117072810011-1, 17-29-05019, АААА-А17-117011810036-3The authors are deeply indebted Joint Russian-Mongolian Complex Biological Expedition RAS and MAS, who supported the field observation and data collection used in this study.

    TRY plant trait database - enhanced coverage and open access

    Get PDF
    Plant traits-the morphological, anatomical, physiological, biochemical and phenological characteristics of plants-determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodiversity conservation, ecosystem and landscape management, restoration, biogeography and earth system modelling. Since its foundation in 2007, the TRY database of plant traits has grown continuously. It now provides unprecedented data coverage under an open access data policy and is the main plant trait database used by the research community worldwide. Increasingly, the TRY database also supports new frontiers of trait-based plant research, including the identification of data gaps and the subsequent mobilization or measurement of new data. To support this development, in this article we evaluate the extent of the trait data compiled in TRY and analyse emerging patterns of data coverage and representativeness. Best species coverage is achieved for categorical traits-almost complete coverage for 'plant growth form'. However, most traits relevant for ecology and vegetation modelling are characterized by continuous intraspecific variation and trait-environmental relationships. These traits have to be measured on individual plants in their respective environment. Despite unprecedented data coverage, we observe a humbling lack of completeness and representativeness of these continuous traits in many aspects. We, therefore, conclude that reducing data gaps and biases in the TRY database remains a key challenge and requires a coordinated approach to data mobilization and trait measurements. This can only be achieved in collaboration with other initiatives
