The Given

Since the mid-1970’s, the landscape around the confluence of the Morava and Dyje rivers has undergone substantial changes related to the drop of water table caused by water management measures undertaken on both ri-vers. Periodical spring floods are among the phenomena lost due to ameliorations. In this study, the reaction of forest ecosystems to the decrease in soil moisture is assessed on the basis of changes in species composition of the herb layer as well as of the known requirements of individual recorded taxa and the entire herb synusiae for the water content of soils. The results confirm that the species with the greatest demand for water disappear over time. The tendency of decreasing Ellenberg indicator values of the herb layers within the phytocoenological relevés is obvious also with the consideration of the influence of different numbers of species recorded on the same plots in different years of the survey. The changes are most visible in the dampest habitats, while elevated sites, so-called “hrudy”, tend to be most stable. The intensity of vegetation changes increases in direct proportion to the altitude of the sites. The process of changes in some habitats caused by the alteration of the water regime has to be separated from the changes in the vegetation structure, which are easier to observe optically. The limiting factor of their development in the given conditions is the forest wildlife. After the elimination of wildlife’s influence, the woody species synusia differentiates in height. A qualitative shift is represented by the recession of the formerly dominant <I>Quercus robur</I> on the main level, and its gradual replacement by other species. The impact of changes going on in the woody synusia on selected characteristics of the herb layer are included in the analyses.

And Control

The pine wood nematode (PWN), Bursaphelenchus xylophilus, causes lethal pine wilt disease (PWD) in Asia and Europe and has become a serious threat to global pine forest ecosystems. In Korea, Monochamus saltuarius transmits PWN not only to Pinus densiflora, but also to Pinus koraiensis, which is widely distributed across eastern Asia. The diel rhythmicity of M. saltuarius in response to its aggregation pheromone was studied with the aim of providing reliable data for the prevention of PWD and control of Monochamus spp. Using a spray dispenser controlled with an electronic timer, M. saltuarius pheromone and attractants (PA) were sprayed to determine the diel rhythm of the response to PA. The spraying period was divided into four time periods: 05:00–11:00 (time period A), 11:00–17:00 (time period B), 17:00–23:00 (time period C), and 23:00–05:00 (time period D). The largest number of M. saltuarius was caught in time period B, followed by A, C, and D. It could be concluded that the flight activity of M. saltuarius in response to PA was diurnal. The results of this study improve the understanding of the behavioral biology of M. saltuarius, allowing for the development of pest management strategies to prevent the spread of PWN and control its vector.

The paper presents materials on the study and content of the accumulation of iron and manganese in the woody and herbaceous leaves of the Beskaragai belt pine forest of the dry steppe zone of Kazakhstan, as well as the ratio of iron and manganese to determine the conditions for normal plant life. The results of the research showed that the values of the biotic index in woody and herbaceous plants of the Beskaragay lentchen boron for iron are below 0.3. In the needles of pine trees, none of the zones retained the ratio between iron and manganese for the normal life of pine plants. The accumulation of manganese in herbs occurs mainly from the atmosphere. Of the two biogenic metals, only Mn in the Beskaragai pine forest plays the role of biogeochemical circulation of substances for pine needles. The values of Кн for iron are less than one in pine needles taken from different zones of the Beskaragai forest, which indicates the input of manganese into forest ecosystems, both from the soil and from the atmosphere. The ratio of the concentration of iron and manganese 2: 1, which is necessary for grasses for normal life, is observed only in the zone of unpaved roads of the Beskaragai forest. The work is of great importance for further monitoring of the state of forest ecosystems in the conditions of technogenic and aeronautical pollution of the study area.
