Background. Researchers often discuss the subject of physical activity (PA) of the elderly in theoretical terms, showing, for example, the protective mechanisms of PA for the body, beneficial effects for health and aging, as well as the principles of effective health training. According to the WHO and EU, few elderly people are physically active. This study aimed to investigate the level of PA of the surveyed elderly people at the present time, compared to when they were younger. Potential limitations in PA of the respondents and their knowledge about the dangers of hypokinesia were also investigated. Material and methods. This study assessed 217 people, aged 60-85, living in the northern part of the Lublin Province, Poland. It used an original interview questionnaire. Results. Systematic PA performed by respondents earlier in life involved mainly household and backyard activities, professional work, and participation in physical education lessons. The currently most frequent activities were found to be walking (75.6%) and gardening (66.4%). Women much more often than men participated and reported their willingness to be active in organized PA. Various limitations prevented respondents from being physically active. The greatest number of respondents reported disability, physical weakness, kinesiophobia, and multiple diseases (34.6%) as the main barrier, followed by lack of skills to organize physical exercises (27.7%). Concerning threats of hypokinesia, respondents most often indicated obesity, diseases of the musculoskeletal system, and arterial hypertension. Conclusions. The level of PA of the surveyed elderly people, limitations preventing PA, and low level of knowledge about the delayed consequences of hypokinesia suggests a need for seniors’ health education in physioprophylaxis.

Compared with EU countries, Polish forestry features one of the highest proportions of forests under state ownership reaching nearly 80% of the country’s forested area. At the same time, all the operations related to timber harvest and transports are performed by private contractors. The private contractors have no development strategies. This is caused by a number of factors, such as economic, environmental and social, as well as lack of competition on the services market. Unit rates of 4.4 EUR/hour. to 4.9 EUR/hour for harvesting operations and 4.2 EUR/hour to 4.6 EUR/hour for timber skidding differ significantly from those in European Union states reaching for some operations 10–20% of the rates applied in Sweden or Germany. The low fees and the high costs of equipment purchase and use, as well as the difficulties in ensuring an adequately large and stable scope of work are the barrier in the development of service firms.

The use of Ripley’s K(t) function for analysis of spatial structure of tree stands has recently become easier due to the growing availability of advanced software. Unfortunately not every data set is suitable for analysis with classical estimator of K(t) function. Large directional differences in density of trees in analysed region cause that estimators suggest aggregated distribution of tress even if it is not true. This paper presents the review of proposals to solve this problem based on dividing of the analysed region into homogeneous sub-regions. Analyses carried out on separate sub-regions can furnish viable information about spatial structure of tree stand. Besides, examples of such analyses made with commonly available non commercial software are presented.

Different aspects of living mulches application in vegetable crops production is discussed in the paper. They compete with vegetables for light, moisture and nutrients and for this reason in most cases cause the yield reduction of cash crops. However, at the end of vegetation period, after ploughing down as green manure they enhance the organic matter content in the soil, improve its physical and chemical properties, which are beneficial for the subsequent species in crop rotation. Undersowing is best suited in perennial crops like rhubarb or the species with relatively long vegetation period, grown from transplants (leek, cabbage, sweet corn, stake tomato, pepper). The most important attributes required for species used as living mulches are quick emergence and soil covering, short height, low water and nutrients demands. In most cases the legume crops (white clover Trifolium repens L., red clover Trifolium pratense L., hairy vetch Vicia villosa Roth., seradella Ornithopus sativus Brot.), grasses (perennial ryegrass Lolium perenne L.) or cereals, especially rye Secale cereale L. are used for this purpose. Their competitiveness to the cash crops may be diminished by the delayed term of undersowing the only in strips between plant rows, mowing the biomass or the use of sublethal doses of herbicides. The beneficial effects of living mulches include the suppression of weed infestation, reduced insect pests and diseases pressure, and prevention from soil degradation. They suppress soil compaction, wind and water erosion, improve soil structure, reduce the surface water runoff and nutrients leaching. Living mulch cover is favourable for biological activity of the soil and the amounts of available nutrients after decomposition. Further intensive studies will be needed to introduce such intercropping, friendly to the environment system to the wide practice, especially in the terms of possible decrease of competitiveness to the cash crops.

Subject and purpose of work: The article presents the concept of smart villages formulated in EU documents. Its purpose is to characterize the concept of smart villages - its assumptions, possibilities and implementation limitations. Materials and methods: Literature studies and the analysis of documents. Results: A comparative analysis of the smart villages and smart city concept was performed. The theoretical foundations and the determinants of its implementation were discussed. Conclusions: The concept of smart villages provides an answer to the search for ways of implementing the concept of sustainable development. The concept is in the initial phase of its formulation and application. It is intended to strengthen the territorial capital of the countryside, while social and technological innovations are a tool for its implementation. Among the barriers to implementing this concept the following ones have to be mentioned: low openness of the rural community to change, low innovation capacity and low level of social capital, low capacity of the local markets, spatial distance, poorly developed transport and communication network.

It has recently been suggested that goitered gazelles (Gazella subgutturosa and Gazella marica) have paraphyletic maternal origin, and that the mitochondrial cytochrome b gene fragment can be used for species identification prior to reintroduction of the gazelles. Although there is a large geographic area where the gazelles have intermediate morphology, previous researchers have not inferred any signs of mitochondrial haplotype introgression, and it is thought that the introgression, if it exists, is male-biased. We studied mitochondrial haplotypes of morphologically typical G. subgutturosa from two geographic locations. Goitered gazelles from eastern Turkey, morphologically identical to G. subgutturosa, had haplotypes identical to G. marica. This finding confirms ongoing maternal gene introgression from G. marica to G. subgutturosa. Our suggestion is that there is a natural gene flow between these two nominal species, and morphological characters together with recombinant genetic markers rather than mitochondrial DNA should be used to differentiate among individuals from areas close to the contact zone.

The investigations were carried out from 1997 to 2001. It was shown the function of the leafy shelter-belt as biogeochemical barrier of total length 114 m by changes of different forms of nitrogen in soil (total, nitrate, ammonium and organic) and in the ground water under shelterbelt and also activity of urease in soil. This shelterbelt is located on two kinds of soil. It was found the impact of the edge of the shelterbelt on the changes of different forms of nitrogen in soil and in ground water and also activity of urease in soils. It was observed that the significant impact on the decrease of nitrogen in ground water and in soils exerts the distance from the edge of shelterbelt. The highest decrease of analyzed compounds was observed in the first sector of shelterbelt (16.5 m). Additionally the effect of eluted cations Ca+2 and Mg+2 on the compensation of pH value of the ground water was also observed.

The response of the Baltic diatom Cyclotella meneghiniana to iron deficiency was examined. The following growth parameters were measured: cell number, chlorophyll a and protein content. The results demonstrate the ability of this diatom to grow well with minimal iron availability; however, the rate of growth fell markedly at the lowest iron(III) concentration. The results of spectrophotometric chlorophyll a measurements and protein assays using the Lowry and Bradford methods indicated a significant decrease in their quantities. Iron may therefore be an important regulatory factor controlling the growth of diatom C. meneghiniana in an aquatic ecosystem.

Ecohydrology has the potential to make a significant contribution to the global need for improved water resources management. An investigation was conducted into educational and capacity building activities related to ecohydrology in an effort to better integrate understanding, promote awareness of existing activities, and to recommend action for global knowledge translation. Based on a survey of key partners and a review of the literature, three key observations were made: 1) consistency in the use of the definition and key concepts behind ecohydrology must be achieved, 2) development of a framework for courses in ecohydrology be developed for application on a regional and global scale and 3) there may be existing educational materials on ecohydrology but they are not well publicized or accessible even to seasoned practitioners. These recommendations are currently being implemented with the development and testing of three pilot courses.

Following the limitations regarding the use of the neonicotinoids: clothianidin, thiamethoxam and imidacloprid there are no currently available insecticide seed dressings for oilseed rape in Poland. For maize here is only one seed dressing containing methiocarb available with a very narrow registered scope of use. The impact of limitations on protection possibilities of other major Polish agricultural crops is either negligible or non-existent. In consequence a group of economically important insect pests of maize [dungbeetles (Melolonthidae); click beetles (Elateridae); noctuid moths (Agrotinae)] and oilseed rape [leaf miners (Agromyzidae), turnip sawfly (Athalia colibri Christ.), cabbage weevils (Curculionidae), cabbage root fly (Hylemyia brassicae Bche.), diamond-back moth (Plutella maculipennis Curt.)] is left without any legal possibility of chemical control. For the other important pests of the early growth stage of oilseed rape development, there are only pyrethroids available together with one product containing chloropiryfos that can be applied once per vegetation season. Since both maize and oilseed rape are grown in Poland on the area of approximately 1 million ha (each crop), this situation raises concerns about production possibilities as well as development of pest resistance.
