Устойчиво земеделие – глобални идеи и локалното им приложение в България. Тенденции и нагласи

Author(s): Atanaska Stancheva / Language(s): Bulgarian Issue: 2/2017

The aim of the article is to show how and to what extent global ideas for sustainable development and use of natural resources are understood and implemented in Bulgaria by revealing and analyzing some of the specifics of two parallel and interconnected trends aimed at achieving sustainable agriculture. These are organic farming and relocalization of food through the implementation of the concept of food sovereignty represented on the local level by Hrancoop movement. The views of the bio-farmers and their connectedness to the concepts of alternative agriculture are also presented, as well as the policies, regulations and subsidies in the agricultural sector and the protection of the environmental. Crucial for the producers are personal motives, interest and experience rather than particular global ideas.

Фенотипічна мінливість листків рослин роду Acer, інтродукованих у степову зону України

Author(s): I. O. Zaitseva,M. M. Povorotnaya / Language(s): Ukrainian Issue: 2/2014

This paper deals with studying of the patterns of ecological adaptation of wood species of Acer L. genus during their introduction into steppe zone of Ukraine. Hydrothermal conditions of the growing season in steppe zone of Ukraine are particularly unfavorable for tree and shrubbery plantings, comprising both native and introduced species. In the course of plants’ introduction, adaptive changes occur; such changes represent the spectrum of phenotypic implementation of the definite genotype under the influence of new environmental conditions. Stress environment of the region of introduction leads to occurrence of a great variety of phenotypic forms, as the different variants of genotype implementation. Studying of phenotypic variability gives an opportunity to determine the capacity to adaptation of introduced species and ways of adaptive reactions in new conditions of living. Therefore, objective of the work consists in studying of the processes of differentiation of morphological characters in species of Acer genus introduced in the regions of steppe zone with varying intensity of hydrothermal factors. Studies were carried out in the central and south-eastern steppe regions, as well as in the south of steppe zone in the coastal and continental areas. Subjects of research were 9 species of maples, differing by their botanic and geographic origin and by the degree of drought resistance in the steppe zone of Ukraine. Patterns of variability of morphostructural characters of leaves were determined by the indicator of specific weight of leaves which was calculated as a ratio of weight of dry laminas to their area (mg/cm2). Following the results of study, it was found that adaptation of maples to xerothermic factors of the environment is connected with changing of the ratio of groups of character variation and their contribution into total sample. Direct relationship is established between the probability density of expression (phenotypic implementation) of the character in the definite range of variation and degree of adaptation of the plant. Typical feature of species with the most prominent xeromorphic characters (A. campestre, A. tataricum, A. monspessulanum) is gradual increase in both the mean value of one of the components of the leaves’ specific weight distribution curve and its contribution in the total sample with the increasing hydrothermal stress. In maple species with low stability, probability of the character display is actually the same for each segregate component of total sample in the different regions of steppe zone, which indicates that these species has no adaptive potential to be realized in the specific environment. Eco-climatic adaptation of mesophytic maple species is displayed in reduction of confidence intervals in the segregate components of the integral curve and reduction of total interval of variation of specific weight of leaves, i.е. it is aimed at decrease in phenotypic polymorphism of introduced species of Acer genus in the drought conditions of steppe zone of Ukraine

Author(s): L. D. Orlova / Language(s): Ukrainian Issue: 1/2011

The accumulation of litter on upland meadows in the studied area was calculated as 30.9–190.1 g/m2. For convenience the reserves can be divided into three groups. Depending on the weather conditions (temperature and rainfall) the litter consists of particular groups and has specific content of solid matter. The energy content of the studied meadows’ litter fluctuated in the range of 36.9–837.0 kkal/m2 and depends on the part of grass stand: upper, middle or lower one.

Функциональная структура сообщества мезопедобионтов дерново-боровой почвы арены р. Днепр

Author(s): O. V. Zhukov,O. N. Kunah,V. A. Novikova / Language(s): Russian Issue: 1/2016

We revealed the functional groups of the animals of sod pinewood soils (arena of the river Dnepr in the "Dneprovsko-Orelsky" Nature Reserve) on the basis of cluster analysis of the RLQ-axes received as result of interaction of matrix of community, matrix of edaphic parameters and matrix of ecomorphs of soil animals. The quantitative account of soil mesofauna has allowed us to establish that the community of animals inhabiting sod pinewood soils is represented by 20 species at a density of 68.9 ± 14.6 ind./m2, 8 forms were identified at the level of genus, family or order. Two species were represented by their larval and imago phases (Anatolica eremita (Steven, 1829) and Calathus ambiguus (Paykull, 1790)). A count of animals conducted in an alternative way has allowed us to expand the list to 38 species or forms at species level. The level of abundance and diversity for sod pinewood soils on the arena is not high compared with other types of soils of the arena of the river Dnepr. This result shows that the community has a simplified ecological structure. The prevailing ecological structure of the community can be characterised as steppe, xerophilous, oligotrophocoenomorphic. Anecic animals are absent from the topomorphic structure and saprophagous animals absent from the trophic structure. Only additional collection by alternative methods has allowed us to establish the presence in the community of saprophagous and anecic animals. The latter ecological group is represented by the extremely mobile vertebrate species Pelobates fuscus. The foromorphic structure of the community differs by its great variety. In this structure various strategies of animals’ movement through the soil are proportionately represented. On the one hand, we see various ways of movement of herpetobiont animals, mainly insect imagoes, which as a whole differ in their considerable migratory potential. This circumstance staticizes the historical reasons for the formation of the studied community. On the other hand, in the community there are various strategies of movement in the soil that allow us to assume or determine the reasons or causes of structurization of an ecological niche. Environmental factors are described by two groups of indicators, edaphic properties and values of phytoindicator scales. The mesopedobionts community structure is presented as a classical matrix of species/sampling points. The ecology of communities is principally focused not on taxonomic features but on biological properties (traits) of species. Such features can act on ecomorphs of soil animals. The direct functional analysis of relationship of biological properties of species with variables of environment by means of data on the abundance of species demands association of three matrixes of data. Such problem can be tackled by means of the RLQ-analysis. A key aspect of structurization of communities of soil mesofauna is differentiation in trophic traits. The organisation of a community of soil animals in an ecological space set by axes RLQ can be displayed in the form of a natural variation of RLQ-axes in geographical space. Everything in the RLQ is represented, as follows from the mathematical nature of this generalisation, an independent aspect of the coordinated variation of structure of a community of soil animals, properties of environment and ecomorphic features of mesopedobionts.

Author(s): A. A. Marchenkovskaya / Language(s): Russian Issue: 1/2006

Research of biochemical parameters of two aquatic amphibian species was conducted in biotopes of the channel Dnieper-Donbass. Finding data showed a high level of protein and lipids in animal organs and tissues. That testifies to the large energy resources of the organisms and allows estimating both separate individuals and populations as stable ones – which are able to the further growth.
