Aim. The aim of the article is the following: to analyze the historical materials on the creation of the Botanical Garden arboretum; to investigate the age structure of the dendroflora collection; to study the taxonomic composition, biometric indicators, the sanitary condition of the age-old trees, and their significance in cultural phytocoenoses. Materials and Methods. The study is based on the materials of inventory of woody and shrub plants of the arboretum and literary sources related to the analysis of the quantitative and qualitative composition of the dendroflora collection. Results. Arboretum of the Botanical Garden of Ukrainian National Forestry University is one of the oldest dendrological collections in Lviv. The collection includes 28 age-old trees. Their age exceeds 100 years, biometric indicators are significant, and sanitary state, both for a specified age and taking into account urbogenic growth conditions, is good or satisfactory. Some age-old trees (black walnut, katsura-tree, American witch-hazel) are the oldest species in the West of Ukraine and have the largest biometric indicators. Conclusions. The arboretum of the Botanical Garden of UNFU is a unique heritage of garden and park art of the XIX century. The historical composition of the dendroflora is partially preserved. Among the age-old trees, there are both autochtonic and introduced species. Trees are in a good sanitary state. They are an integral part of the formed phytocoenosis. As an object of observation, they can be used for further research of potential ecological and biological capabilities of species in an urbogenic environment.

As a result of nature resources intensive use, most of ecosystems have beenconverted. Anthropogenic impact includes changes of forest stands structure andtheir spatial specificity in the forest area. Accordingly the sanitary state of Norwayspruce young forest stands can be affected by different risk impact factors ofmanagement. The aim of the research was to analyze the spruce Picea abies (L. )Karst. young forest stands sanitary condition depending on forest plots spatialspecificity and location in the forest areas. The data were collected in 4 regions ofLatvia in spruce young forest stands (1 - 40 years old). The research was conductedin young natural and artificial stands (pure – 44, mixed – 42). In total 502 sampleplots with a total area of 28250 mwere installed. The particular plot size (25, 50,100 and 200 m) were selected depending on the stand average tree height, whiletheir number depended on the forest stand area. A total area of investigated foreststands were 127. 5 hectares. Results showed that the expression of spatial specificsdepended on risk factors and their intensity, as well as the environmentalcharacteristics. Damages caused by abiotic risk factors at different forest standswere not the same regarding intensity, nature and volume, but more or less closelywere related to all site conditions. Spatial specificity of forest stands area (regularand irregular), as well as their location in the forest massif significantly affects thespruce young forests sanitary status (respectively p=0. 027 and p=0. 002). Differentrisk factors damage to forests, bordering with spruce or pine young growths,cutovers and various types of infrastructure, were identified as much moreimportant.

В Нижнем и Верхнем дендрологических садах Санкт-Петербургского государственного лесотехнического университета в Санкт-Петербурге выращивается 13 видов и 1 гибрид рода Larix Mill., представленных 124 экземплярами, в возрасте от 25 до 200 лет. Все зимостойки, образуют шишки, 3 вида (L. archangelica, L. decidua, L. sibirica) дают самосев. Всего за период интродукции были испытаны 23 таксона рода Larix, наибольшее число видов здесь впервые испытал Э.Л. Вольф. Некоторые виды (L. komarovii, L. maritima) здесь были впервые введены культуру. В коллекции сохранились старовозрастные экземпляры, посаженные еще в XIX в. – 71 шт., самые старые посадки (9 деревьев) датируются 1820 г. (L. archangelica, L. decidua, L. sibirica). Самое высокое дерево относится к L. sibirica: 34,0 м выс., самое толстое по диаметру ствола – L. decidua: 102 см. Исследования подтверждают важность периодических биометрических измерений и непрерывного мониторинга коллекции. Отдельные деревья заслуживают внесения в базу данных по деревьям-чемпионам по их размерам в высоту и диаметру ствола. There are 13 species and 1 hybrid of genus Larix Mill., represented by 124 trees, in collection of the Upper and the Lower dendrological gardens of Saint-Petersburg State Forest-Technical University, under the age from 25 till 200 years old. All of them are winter hardy and produce cones. Three species (L. archangelica, L. decidua, L. sibirica) give self-sowing. Totally there are 23 taxa which have been tested for the period of introduction. The largest amount of species were tested by E.L. Wolf. Some species (L. komarovii, L. maritima) were introduced here into general cultivation. There are trees of old age planted as early as in the XIX century (71). There are 9 of oldest trees cultivating since 1820 (L. archangelica, L. decidua, L. sibirica). The tallest tree is of L. sibirica: 34,0 m high, the most thick on trunk diameter is the tree of L. decidua: 102 см. The research confirm the importance of periodical biometrical measurements and uninterrupted monitoring of all collection. There are certain trees which deserve to be included into the data base on Champion trees on their sizes.

The study considered the development of ideas about the limits of settling the Ukrainian people in connection with the compilation of ethnographical map of the Austrian and Russian monarchies, since the 40s of XIX century. The views of Ukrainian and Russian researchers who have studied this issue during different periods are analysed. In the manuscript “Geography of Ptolemy” in 1420 (the author is unknown), the map “Sarmatia” (Sarmatias) (the name of the map is conditional) Ukrainian lands were depicted for the first time and for the first time the map contained the inscription “Sarmatia”. Nicolaus Hermanus, who revised the content of “Geography” by Claudius Ptolemy (Cosmographia Claudii Ptolomaei Alexandrini Manuscript, 1467), first placed the name “European Sarmatia” (Sarmatia Єvropє) on the handwritten map of 1467. In the second (the first one with maps) Bologna edition 1477 (26 maps) of Claudia Ptolemy's “Geography” also contained a map of “European Sarmatia”. In the next Roman edition (1478) the Eighth Map of Europe (Octava Europe Tabula) and the Second Map of Asia (Secunda Asiae Tabula) are contained, which the Ukrainian lands are depicted in. Based on a detailed study and analysis of cartographic sources, summarizing the results of ethnographic, historical and geographical research of Ukrainian ethnic territory tracked changes in the boundaries of settling the Ukrainian ethnos. In the early nineteenth century in many European countries, regular population censuses had been introduced and ethnographic studies related to the Ukrainian national revival had been intensified. It created objective prerequisites for the beginning of ethnic mapping in the 1920s and became possible to map the composition of the population in detail, literally by settlements, to determine the absolute and relative share of a particular nationality in a certain territory. The main cartographic works of Ukrainian and Russian scientists, which depict the Ukrainian ethnic territory, are chronologically highlighted. Many ethnic maps have been described. On the basis of elaboration of a considerable number of cartographic and literary sources, the history of ethnographic mapping of the territory of Ukrainian settlements is chronologically covered. Key words: ethnographic researching, map, Ukrainian lands, ethnos.

The author investigated, recorded, observed and analyzed the major wildflowers in Mount Huangshan---the natural and cultural heritages listed by the ESC0 of UN for the first time. On the basis of their desirable characteristics, more than 300 wild ornamental species are divided into 8 categories -–-historical old trees, rare and endangered species, evergreen ornamentals, blooming trees and shrubs, plants with colored foliage and fruit in fall, vines, herbaceous ornamentals and ground covers, and ornamental ferns. Mount Huangshan is one of the richest regions of native ornamentals in Eastern China and the most famous natural beauty in Pan-China. There are about 1500 wild landscape plants in and around it. Finally the paper puts forth some proposals and methods for introduction and utilization of wild ornamental plants. That is, investigation, classification,acclimatization and cultivation of them, and building a sort-out botanical garden for the germplasmic preservation and the flourishing landscape tourism.


Purpose. Life, scientific and pedagogical way of А. М. Krasnov at the time of the formation of geography was unique, versatile, often contradictory, but clearly creative and innovative approach to everything that was within his interests. Despite some hasty results that harmed his general authority, the figure of A. M. Krasnov – the professor of Imperial Kharkiv University, the founder of Batumi Botanical Garden – is still of interest. Attention has veen paid to the period of his initial formation as a scientist, communication with V. I. Vernadsky, comparison of A. M. Krasnov’s works with works of other researchers, the implementation of the idea of plant introduction. Method. Authentic scientific works of A. M. Krasnov and his contemporaries have been used in the work. Through the use of historical and historiographical sources and comparative analysis there have been revealed those inconsistencies in his works which caused sharp criticism of reviewers. Results. Studies of the work of the first domestic doctor of geographical sciences Andriy Mykolayovych Krasnov have showed his passion for expeditionary research, charisma, thirst for knowledge, love of nature, rich innovative heritage. Attention has been paid to the initial stage of his life, when the interest in scientific, in particular, expeditionary research, which did not leave him during his life, emerged. Based on the study of the relationship between A. M. Krasnov and V. I. Vernadsky, a conclusion about his extraordinary character, ingrained sense of independence, but also passion, excessive emotionality, haste of conclusions has been made. The authors have given the generalized description of the state of the study of geography, which was considered an auxiliary science in the universities of the Russian Empire in the late XIX century, because for A. M. Krasnov it became a source of innovation. The article reveals the extraordinary scientific courage of A. M. Krasnov, who in his doctoral thesis considered the views of famous scientists on the causes of steppe plains. The analysis of А. М. Krasnov’s publications and other sources has proved that he became the creator of constructive geography, combined theoretical classes with practical ones in nature, initiated student scientific expeditions, founded a student geographical society and a geographical office. Possessing artistic and literary talent, he became one of the best promoters of exotic regions, visiting dozens of countries around the world. The authors have also traced the reasons why his scientific works were treated with skepticism and distrust. Scientific novelty and practical significance. Some details of the relationship between A. M. Krasnov and V. I. Vernadsky have been clarified. The reasons that led to the ignoring of the scientific achievement of A. M. Krasnov by contemporaries have been revealed. It is expedient to use these materials while writing the full scientific and pedagogical biography of professor A. M. Krasnov.

A survey of the larval population of tree hole breeding Aedes mosquito was conducted from January to December, 2010 in four different areas of Dhaka University Campus and its adjacent Suhrawardi park. A total of 689 mosquito larvae was collected during the survey. Among them 396 (57.47%) were Aedes albopictus, 51 (7.02%) were Ae. aegypti and 242 (35.12%) other Aedes species, and the number of male and female among them was counted 347 (50.36%) and 342 (49.63%), respectively. Among the varieties of plant species in the study area only 27 species of trees were found with 56 holes wherein 34 holes of 17 species trees were used by mosquitoes for breeding ground. The highest number (160) of larvae was found in bamboo (Bambusa nutans) stumps hole and lowest (13) in Delonix regia hole. The highest number of larval population was collected in September and the larval population increased from March to September and then gradually decreased. No mosquito larva was found in the tree holes in January and February. The number of larvae collected from different survey areas also varied which were 309 (44.84%), 152 (22.06%), 145 (21.04%) and 83 (12.04%) in Suhrawardi park, and the Arts building, Curzon hall and Botanical garden of Dhaka University, respectively.

AbstractThe paper reports the results of a comparative study of the anatomical structures of the leaf blades of Waldsteinia ternata grown under different light conditions in the Siberian Botanical Garden of Tomsk State University. Waldsteinia ternata is a tertiary nemoral relict from the mountains of southern Siberia, which is found in a limited number of taiga communities due to narrow environmental tolerance to various factors. The species remains poorly studied; comprehensive studies of the anatomical features of its leaves have not been performed on the territory of Russia. Leaves of W. ternata are dorsoventral and amphistomatous with anomocytic type stomata. The plants are classified as mesophytes. The relationship between the development of the anatomical structure of leaves and light conditions was revealed. The W. ternata plants grown in the sun showed an increased number of stomata and epidermal cells, an increased thickness of the leaf and mesophyll, and an increased number of cells of the upper and lower epidermis, that is, the plants exhibited heliophytic features of plant adaptation to good light conditions. At the same time, the vascular tissues of the plants grown in the sun were less developed, which reflected their adaptation to unfavorable water conditions. A number of relative indicators, such as the stomatal index of the lower epidermis, the ratio of the palisade to spongy mesophyll, and the ratio of xylem to phloem, did not change under different growth conditions. Thus, under different light and water conditions, W. ternata acquires helioxeromorphic or sciomesomorphic features.

Abstract The study of geographical forest cultures is the scientific basis for forest-seed zoning and selection of tree species. This research identifies the structural features of the diameter of middle-aged stands of different ecotypes of Scots pine (Pinus sylvestris L.) in geographic cultures, as an assessment of its current sanitary state. We studied the stands of 18 forest-steppe and 14 steppe ecotypes. We laid test areas with measuring the diameters of trees with a measuring fork at a height of 1.3 m. Trees with a continuous count were divided into six categories of sanitary status: no signs of weakening, weakened, strongly weakened, shrinking, fresh dead wood and dead wood of past years. Based on the results of continuous recounts, the distribution rows of trees were constructed according to 2- and 4-cm thickness steps. In forest-steppe ecotypes, the distribution of trees along 2-and 4-centimeter-thick steps is single-vertex, but with right asymmetry. The distribution of trees of steppe ecotypes over 2-cm steps of thickness is asymmetric and two-peaked. The distribution of trees of steppe ecotypes by 2-cm thickness steps is asymmetric and two-vertex. The average score of the sanitary state of stands of forest-steppe ecotypes is 1.5 (healthy), in steppe – 1.7 (weakened).
