The main representatives of meadow Poaceae and Fabaceae of Poltava region are established and their ecomorphic analysis is made 93 species of meadow Poaceae have been found in meadow phytocenoses, which are grouped into 44 genera. Among the found cereals on biomorphs are dominated by perennials (73.0%), on climamorphs among them approximately the same number of cryptophytes and hemicryptophytes, consideration of hygromorphs of the family indicates the predominance of mesophytic plants (56.0%), the bulk of species by tropomorphs belongs to mesotrophic (46.0%), viewing heliomorphs of identified family members indicates their photophobia. 71 species of Fabaceae belonging to 16 genera were found in the meadows. According to biomorphs, most of the identified species are perennials (73.0%). According to ecomorphs, mesophilic, light-loving species, which love soils of medium richness (more than half of all identified species), predominate among the studied species. The consequences of studying the protein in meadow Poaceae and Fabaceae of Poltava region are given. The total protein accumulation in the species studied by us was in the range of 2.5–25.8%. The average values for families are given and specific quantitative indicators of separate genera and species are given. The division of the studied species into three groups according to the content of the indicator is proposed: with low (up to 6.9%), medium (7.0-13.0%) and high (more than 13.0%) number. The studied species were analyzed on a scale of protein content (from 0 to 20 points). According to the given score, the studied cereals are in the group of species with low and medium content, and legumes - medium and high. In the dynamics of protein content during the phases of the growing season you can see a certain trend. Maximum protein is accumulated by representatives at earlier stages of ontogenesis. Analysis of the indicator, depending on their relationship to the biomorph showed some patterns. Thus, annual species, on average, contain an indicator at the level of the second group, and perennial - all three groups. Two-year-olds most often have protein at the level of the third group. This is understandable because they need a lot of nutrients for overwintering and active flowering and fruit formation next year. Moisture conditions also affect protein accumulation. Thus, the studied xerophilous Poaceae according to our research have 9.2 ± 0.4%, mesophilic - 8.2 ± 1.2%. Proven value biomorfy to quantify protein content. It is shown that the concentration parameter affecting growing conditions, including moisture.

Forest ecosystems play an essential role in climate stabilization, and the study of influence of climate change on their biomass and carbon depositing is of paramount importance. The objective of this study was (a) to verify the operation of the law of the limiting factor at the transcontinental level when modeling changes in the biomass of trees and stands of the two-needled subgenus Pinus sp. of Eurasia in relation to geographically determined indicators of temperatures and precipitation, and (b) to show the possibility of using the constructed climate-conditioned models of tree and stand biomass in predicting temporal changes in tree and stand biomass based on the principle of space-for-time substitution. As a result of the implementation of the principles of the limiting factor and space-for-time substitution, a common pattern has been established on tree and stand levels: in sufficiently moisture–rich climatic zones, an increase in temperature by 1°C with a constant amount of precipitation causes an increase in aboveground biomass, and in moisture–deficient zones - its decrease; in warm climatic zones, a decrease in precipitation by 100 mm at a constant average January temperature causes a decrease in aboveground biomass, and in cold climatic zones - its increase.

Evaluation of the progeny test of plus trees of Scots pine - a necessary condition for determining the prospects the use of improved seeds in different environmental conditions. The paper presents the results of the study of the progeny test of groups of clones of plus trees of Scots pine selected according to certain characteristics in Northern Steppe and South Forest-Steppe of Ukraine. Analysis of results showed: a significant improvement in the growth rates of the all testing progenies of seed orchard in the better climatic and soil conditions of South Forest-Steppe between the ages of 3 and 10 years. At the same time 4 out of 5 studied progenies worsened their growth indicators relative to local control at the age of 3 to 26 years in less optimal climatic and soil conditions of Northern Steppe. The leader in the steppe conditions was the progeny of a fraction of three clones, which had the highest seed productivity. The selection of the fastest growing clones and the rejection of the slowest growing ones had a positive effect on the growth of progenies of seed orchards at both test points.

Due to the low dietary value of crops, Zn-deficient soils and insufficient intake of other minerals, soil fortification is often necessary. Fortification is defined as the addition of one or more crucial nutrients to a food to reduce poverty in a population or specific population groups. Currently available technologies for rice fortification with vitamins and minerals are high-energy and time-consuming methods. Therefore, mineral enrichment of crops has received much attention from scientists. The originality of the current study consists in determining the optimal use of hard hazelnut shells, orange peel and rice husks for enrichment of paddy soil and simultaneous immobilization of heavy metals. The combination of the identified wastes, namely hazelnut shells, orange peel and rice husks, showed good potential for immobilization/elimination or reduction of heavy metals to less than permissible limits. Therefore, the use of this combination could be an effective strategy to both introduce new micronutrients into rice grain and remove heavy metals.

Limitation the number of ixodes ticks is one of the most important tasks of modern science and requires the search for new, highly effective and environmentally hazardous acaricides, so our experiment was aimed at identifying acaricidal properties of essential oils and their individual active components in the population of ixodes ticks in Zaporizhzhia region. The study of acaricidal properties of essential oils was performed in the laboratory conditions. Tampons with wool were soaked in various concentrations of 0.5%, 1%, 3%, 5% and 10% aqueous emulsion of essential oils such as Caryophyllus floris aetheroleum and Limonis aetheroleum, and essential oils of Thymus serpyllum L., Рinus sylvestris L., Salvia officinalis L., Mentha x piperita L. and Eucalyptus viminalis Labill. The essential oils had a significant effect on the lifespan of adult ticks. The results showed the acaricidal effect of Thymus serpyllum essential oils. When searching the acaricidal and repellent properties of individual essential oils components thymole, menthol and citral showed the high activity as acaricides. In the same time, eugenol and borneol proved the effectiveness as repellent. Our research schowed that essential oils are promising as alternative methods of controlling the number of Ixodes ticks in areas where there are conditions for infection with tick infections.

Increasing human population and various developmental activities in the Indian state of Arunachal Pradesh, which lies in one of the most bio-diverse regions of the world, has caused large-scale deforestation, pushing a large number of native tree species to the serious verge of elimination from their native forest. In such tribal-dominated landscapes around the world, myriads of studies have emphasized the potential of homegardens as a site for local biodiversity conservation as they are known to have a huge Indigenous Knowledge System (IKS) on the use of diverse native floras. The present study was, therefore, undertaken to investigate if the native communities of the Mishmi tribe conserved native indigenous tree species in their homegardens and if they are grown then what is the future of these tree species? It was hypothesized that harbouring greater indigenous knowledge implies greater domestication of tree species in their homegardens. Altogether, 103 species of trees were recorded from 243 homegardens in the present study. Although the native species constituted more than half of the species diversity, they, however, greatly lagged in all other aspects of the study such as population share, frequency distribution and regeneration potential. Native tree species constituted just 37% of the total tree population. Only two species, Bauhinia variegata L. and Alnus nepalensis D. Don, made up the major bulk of the native population. In terms of frequency distribution, only a handful of native species maintained a decent presence in the homegardens. Most of the native species grew naturally in unmanaged homegardens. The regeneration potential of all native species was very poor, including B. variegata. The study demonstrates that out of the 76 native species recorded from the region, only 7 species can rightfully be regarded as being domesticated by virtue of IKS of the Mishmi community. Our study concludes that the native species do exist in large number in homegardens of the rural tribal areas, but most of the native wild species exist in the rural homegardens not because they are planted/preferred but because they just happen to randomly grow there since most of the homegardens of tribal household are unmanaged or poorly managed, thereby giving way to wild species to germinate, at least until the owner decides to weed them out.
印度**邦是世界上生物多样性最丰富的地区之一,人口的增长和各种发展活动造成了大规模的森林砍伐,将大量本地树种从其原生森林中推向了灭绝的严重边缘。在世界各地以部落为主导的景观中,无数的研究都强调了家庭花园作为当地生物多样性保护场所的潜力,因为它们在利用各种本地植物群方面拥有庞大的土著知识系统(IKS)。因此,目前的研究是为了调查Mishmi部落的土著社区是否在他们的家庭花园中保护了当地的土著树种,如果它们被种植,那么这些树种的未来是什么?据推测,拥有更多的本土知识意味着在他们的家园中驯化更多的树种。本研究共在243个家庭花园中记录了103种树木。虽然本地物种占物种多样性的一半以上,但在种群份额、频率分布和更新潜力等方面的研究都远远落后。本地树种仅占树木总数的37%。只有紫荆(Bauhinia variegata L.)和尼泊尔桤木(Alnus nepalensis D. Don)这两个物种构成了本地种群的主要部分。在频率分布方面,只有少数本地物种在家庭花园中保持了良好的存在。大多数本地物种在无人管理的家庭花园里自然生长。所有本地种的更新潜力都很差,包括斑叶甘蓝。研究表明,在该地区记录的76种本地物种中,只有7种可以被合法地认为是通过Mishmi群落的IKS驯化的。我们的研究得出结论,在农村部落地区的家庭花园中,本地物种确实大量存在,但大多数本地野生物种存在于农村家庭花园中,不是因为它们被种植/偏爱,而是因为它们碰巧随机生长在那里,因为大多数部落家庭的家庭花园都没有管理或管理不善,从而让野生物种发芽,至少在主人决定清除它们之前。

Intensive urbanization processes, an increase in the number of urban population and transport have led to an increase in the technogenic load on the environment, in particular on the atmospheric air. Among a significant number of sources of environmental pollution, roads and vehicles pose a significant threat. Motor vehicles cause irreparable harm to human health and the environment. Regular assessment of the quality of atmospheric air in residential areas of cities with heavy traffic to establish the level of potential risk to public health is an urgent task. The study purpose is the social consequences of transport emissions; determination of the anthropogenic load on the air and of the indicator of public health risk from the vehicle exhaust impact. The study was carried out on the example of the residential and the most loaded transport area of Poltava (Ukraine). The study demonstrates that the overwhelming majority of the urban population lives in areas where health risk indicators exceed permissible norms. Since the elderly, children and students are most often present on the street and near houses, they are at the greatest risk. The same applies to vehicle drivers who are often idle in "traffic jams". In turn, such high levels of air pollution pose even greater risks to public health, in particular to the development of respiratory diseases.

Among a significant number of sources of environmental pollution, roads and vehicles pose a significant threat. Motor vehicles cause irreparable harm to human health and the environment. Regular assessment of the quality of atmospheric air in residential areas of cities with heavy traffic to establish the level of potential risk to public health is an urgent task. The study purpose is the social consequences of transport emissions; determination of the anthropogenic load on the air and of the indicator of public health risk from the vehicle exhaust impact. The study was carried out on the example of the residential and the most loaded transport area of Poltava (Ukraine). The study demonstrates that the overwhelming majority of the urban population lives in areas where health risk indicators exceed permissible norms.

Sustainability of woody species in riparian forests requires information on its regeneration status, which is crucial for proper management and conservation of these species but the information is generally lacking in Nigeria. This knowledge of the regeneration status of common woody species in riparian forests guarantees their survival through proper management and conservation. Sampling was done via random method in which five (5) 10 m × 10 m plots were selected from the study sites giving a total of 45 plots. Therefore, the aim of the study was to assess the structures and status of common woody species in the regeneration layer of riparian forests. There was no significant (p > 0.05) difference in the mean seedling and sapling densities of the common woody species across the riparian forest sites. The regression slope showed on-going regeneration (mostly weak) of the common riparian woody species in all the sites. The regeneration structures indicated reverse J-shaped and have been greatly modified by prevalent anthropogenic activities in the study area. The pattern of regeneration status observed in the seedlings and saplings emergence in the regeneration layer was due to the similar environmental factors that occurred from one site to the other. The intermediate values of tree/shrub ratio shown by the common woody species encountered in the regeneration layer indicated more individuals of shrub size than tree and emphasized the fact that the level of disturbance on-going was moderate across study and possibly that the sites were recovering from disturbances.
河岸森林中木本物种的可持续性需要有关其再生状况的信息,这对这些物种的适当管理和保护至关重要,但尼日利亚普遍缺乏这方面的信息。这种对河岸森林中常见木本物种更新状况的了解,通过适当的管理和保护,保证了它们的生存。采用随机抽样方法,从研究点中选取5个10 m × 10 m的样地,共45个样地。因此,本研究的目的是评估河岸林更新层中常见木本树种的结构和现状。各河岸林样地常见木本树种的平均幼苗和幼树密度差异不显著(p > 0.05)。回归坡面显示,各样地常见河岸木本物种在持续更新(多为微弱更新)。再生结构呈“反j”型,并在人类活动的影响下发生了较大的变化。更新层幼苗和幼树的更新状态模式是由不同地点发生的相似环境因素造成的。更新层中常见木本树种的乔灌木比的中间值表明,灌木个体比乔木个体多,并强调了整个研究中正在发生的干扰程度是中等的,可能是这些站点正在从干扰中恢复。
