The formation of park-monuments of landscape art was analyzed from a historical perspective. In the second half of the twentieth century, two national and nine local park-monuments of landscape art were created in Ukrainian Polissya. The purpose of PMLA is the protection and the preservation of the most prominent and valuable examples of park construction in order to use them for aesthetic, educational, scientific, environmental and health purposes. By the placement in the planning structure of inhabited localities are defined city, village and district parks. The motivation for the creation of parks was the preservation, reproduction and enrichment of tree diversity in the conditions of the Ukrainian Polissya. In the parks were planted technical, fast-growing, rare species, and species of woody plants valuable for forestry and landscape gardening with their subsequent use for scientific and economic purposes. Some of the plantations in the parks were memorable, anniversary, or dedicated to significant events (the anniversary of the October Revolution and the birthday of V.I. Lenin). In Ukrainian Polissya, there are three parks created on the basis of existing oak plantations “Klevanskyi Park”, “Park Antonivka”, “Bondaretskyi”); one - on the basis of man-made plantations with Acer platanoides L., Carpinus betulus L., Fraxinus excelsior L., Tilia cordata Mill. (“Ovrutskyi”); three parks of culture and recreation (“Horodnianskyi”, “Vysokivskyi”, “Slovianskyi”) including a meadow park (“Slovianskyi”), a children's park (“Bondaretskyi”), three arboretums (“Dubechnenskyi”, “Bairak”, “Novostavskyi dendropark”, “Zhornivskyi”), which were transformed over time, or which were granted the status of PMLA. By the size, PMLA were small, medium, and large with star, axial, fan, loop, cross-shaped and combined planning structures. In four PMLA, there were man-made and natural reservoirs, and a fountain. Five parks were combined (memorial and park of culture and rest); there were concentrated memorial complexes, monuments, and an obelisk. Plantings of parks are represented by groups, solitairs, alleys, ordinary plantings, hedges, and sometimes by groves and massifs. On the territory of 11 PMLA grew 178 species of woody plants, with 121 of them being included to the IUCN Red List. In 4 parks, since their creation the number of species increased by 75–129%; in 6 parks tree diversity decreased, with 29 to 87% of tree plant species remaining, among them 66–94% of trees were rare. 11 PMLA are valuable centers of tree diversity and unique plantings of Ukrainian Polissya; and an example of the formation of didactic, ethnographic, memorial, children's, culture and recreation, and combined parks that need further protection and expansion of the area and collection. Some parks are in need of planting reconstruction.

Elements of topiary art were studied in eleven park-monuments of landscape art (PMLA) and five complex monuments of nature (CMN), created in the second half of the twentieth century. To the elements of topiary art belong: shaped plants, plant-borders, hedges, living walls, pylons, berso, bosquets, and parterres. In PMsLA “Bondaretsky” and “Vysokivsky” were found no elements of topiary art. In nine PMsLA and five CMsN of Ukrainian Polissya were present five elements of topiary art (plant-borders, hedges (low, medium, high), living walls, pylons and shaped plants (ball, pyramid, cone, cube, complex geometric figures). The most common are plant-borders formed from Buxus sempervirens L., trimmed hedges from Picea abies Karst. and Thuja occidentalis L., untrimmed hedges from Juniperus sabina L., Physocarpus opulifolius Maxim., and Sorbaria sorbifolia (L.) A.Br., pylons and shaped plants in the form of a sphere, cube, complex geometric shapes - from Thuja occidentalis L. 12 families, 24 genera, 24 species, and 3 cultivars represent the systematic structure of woody plants in the elements of topiary art. Deciduous species of woody plants, namely the family Rosaceae Juss, prevail. In the elements of topiary art of PMLA and CMN there are species that are protected by the IUCN Red List (58 %), belonging to two categories of rarity NT (4 %), LC (54 %). In terms of the height of woody plants in the elements of topiary art, trees and shrubs are represented in equal numbers. By height, among tree plants prevail trees of the first magnitude 26 % and medium bushes 29 %, whereas there are slightly fewer trees of the fourth magnitude (15%) and high bushes (22 %). The condition of woody plants of 24 species and three cultivars is good, except for woody plants where timely and proper care was not carried out (formation of longitudinal and transverse profiles and annual pruning). Some plants should be replaced because of loss of aesthetics due to age.

Purpose. To give an objective assessment of the current ecological condition of artificially created objects of the nature reserve fund. Methods. Comparative-geographical, generalization, systematization, statistical, comparative-analytical, descriptive, cartographic. Results. Not all types of artificial objects of nature reserve fund of Volyn region are represented. There are 12 park-monuments of landscape art, 1 botanical garden, 1 zoo and no dendrological park. On the whole, the number of artificial objects of nature reserved fund in the region is the lowest in Ukraine. On the territory of the region there is an uneven distribution of artificial objects of the nature reserve fund. An analysis of the distribution of artificial objects of nature reserve fund by area revealed that the largest one is the park-monument of landscape art «Slovianskyy» (27,35 hectares). It is located in the Volodymyr-Volynskyy district. From 12 to 21,6 hectares of landscapes in Lutsk, Gorokhiv, Turiysk, Lyubeshiv and Kivertsy districts is occupied by the park- monuments of landscape art. In the Starovyzhivsky district, the area of park-monuments of landscape art is 2 hectares, while in other districts there are no areas for artificial objects of nature reserve fund. All artificial objects of nature reserve fund were created in 1960-1990. Only one park-monuments of landscape art was created in 2018. It is called «Sydorukiv Park» and is located in the city of Horokhiv. Most of the park-monuments of landscape art are located within settlements and only 2 parks are located in the territory of forestry. In total, more than 150 species of flora are protected in the territory of park-monuments of landscape art. Conclusion. As a result of the analysis, 3 species of flora were identified that grow on the territory of parks of monuments of landscape gardening art and are included in environmental lists (Epipactis helleborine, Syringa josikaea, Epipactis palustris). The most dangerous for them is tearing, digging, picking up bouquets, as well as a partial violation of the structure of ecotopes (deforestation, excessive recreation, etc.). It is proposed to strengthen the protection of these species by increasing the status of the nature conservation object and assigning them to the territories of the nature reserve fund - botanical nature reserve of local importance.

Клены являются одними из лучших декоративных деревьев, использующихся в озеленении населенных пунктов в России и за рубежом. Актуальной задачей в засушливом регионе является биоэкологическое обоснование оптимизации биоразнообразия представителей рода Acer L. в озеленении общего пользования (парки, скверы, бульвары, уличные посадки) и уточнения рекомендаций производству по осуществлению озеленительных работ с участием видов рода Acer L. В статье представлен ассортимент древесных видов рода Acer L. рекомендованный для оптимизации озеленительных посадок г. РостовнаДону и Новочеркасск. Установлен рейтинг декоративных достоинств кленовых деревьев в сравнении с другими видами, используемыми в озеленении а также декоративная долговечность деревьев в городских условиях. Наивысшие баллы по декоративности у клена остролистного и явора (202 и 201 балл). Декоративная долговечность кленов составляет от 45 до 80 лет. Введение деревьев рода Acer L. в озеленение способствует обогащению ассортимента рекреационноозеленительных насаждений городской среды. Для объектов общего пользования Ростовской агломерации разработан ассортимент устойчивых декоративных древесных растений рода Acer L. для различных типов посадок. В уличных посадках рекомендуется высаживать: Acer platanoides L. A. platanoides Globosum, A. pseudoplatanus L., A. saccharinum L. В качестве солитеров использовать A. platanoides L. и его декоративные формы, A. platanoides Globosum, A. pseudoplatanus L., A. negundo L. (золотистая и пестролистная формы). Для живых изгородей A. ginnala L., A. tataricum L., A. campestre L. Опыты с использованием стимуляторов роста показали, что наилучшие показатели по изменению линейных размеров и накоплению фитомассы получены при использовании Крезацин 0,003 и САН 0,01. Наилучшего развития достигли Acer L. на удобренном фоне с использованием ппрепаратов САН 0,01, Гумат 0,02 и 0,03. Обоснованы вопросы комплексной оценки состояния древесных видов рода Acer L. и базовые агротехнические технологии выращивания посадочного материала для целей озеленения. Разработанные мероприятия по оптимизации видового состава озеленительных посадок способствуют улучшению декоративных функций парковых насаждений. Maples are one of the best ornamental trees used in landscaping settlements in Russia and abroad. An urgent task in the arid region is a bioecological rationale for optimizing the biodiversity of the Acer L. genus in public gardening (parks, squares, boulevards, street plantings) and clarifying the recommendations of production on the implementation of gardening works involving Acer L. The article presents an assortment of woody species of the genus Acer L. recommended for optimizing planting of trees in RostovonDon and Novocherkassk. The rating of the decorative qualities of maple trees has been established in comparison with other species used in gardening as well as decorative durability of trees in urban environments. The highest scores on decorativeness are among maple and sycamore maple (202 and 201 points). Decorative durability of maples ranges from 45 to 80 years. The introduction of trees of the genus Acer L. into landscaping contributes to the enrichment of the range of recreational and landscaping plantings of the urban environment. An assortment of resistant ornamental woody plants of the genus Acer L. has been developed for public facilities in Rostov city agglomeration for various types of planting. It is recommended to plant in street plantings: Acer platanoides L . A. platanoides Globosum, A. pseudoplatanus L., A. saccharinum L. As soliter use A. platanoides L. and its decorative forms, A. platanoides Globosum, A. pseudoplatanus L., A. negundo L. (golden and variegated forms). For hedges A. ginnala L., A. tataricum L., A. campestre L. Experiments with the use of growth stimulants showed that the best indicators of changes in linear dimensions and accumulation of phytomass were obtained using Krezacin 0.003 and SAN 0.01. Acer L. achieved the best development on a fertilized background using SAN preparations of 0.01, Humate 0.02 and 0.03. The issues of a comprehensive assessment of the status of tree species of the genus Acer L. and the basic agrotechnical technologies of growing planting material for gardening are substantiated. Developed measures to optimize the species composition of planting trees contribute to the improvement of the decorative functions of parkland.

The 1960S

Protected man-made parks of Ukrainian Polissya, created in the period of postmodernism, are conservation oriented, historical, cognitive and educational objects. Landscape design is a synthesis of traditions and new transformation trends. On the territories of protected man-made parks, natural existence and distribution of rare species are maintained, endangered and vulnerable species are protected, hydrological functions are improved, and valuable landscapes are preserved. Concentrated in Rivne region, five parks, which have the status of complex natural monuments of local significance, were created in Ukrainian Polissya in the 1960s. According to the results of the analysis of formation and development history, the transformation of complex natural monuments (CNMs) of Ukrainian Polissya for a period of over 60 years is shown. CNMs have a simple planning structure of the following types: cross-shaped ("Vysotsky Arboretum"), star-shaped ("Bilsky Arboretum", "Sarny Arboretum"), loop-shaped ("Rokytne Arboretum"), and combined ("Tryputnyansky Park"). Of the three parks with regular planning, the biggest change can be observed in the complex natural monument "Bilsky Arboretum". This is due to the growth of hedges, which are not currently formed, and to the violation of the boundaries of meadows, where self-seeding plants appear. The dendroflora of five man-made parks is represented by 157 species, which belong to 19 orders, 32 families, and 81 genera, with 111 of them being included to the IUCN Red List. In two parks during their existence, there was an increase in the number of species by 11-50%, with the number of rare tree species amounting to 50-71%. In three parks under the influence of anthropogenic and ecological factors, there was a decrease in dendrodiversity, with 55-81% of species of woody plants remaining; аmong them 71-75% are rare tree species. Protected man-made areas of Ukrainian Polissya are valuable objects that need to be further developed and protected, whereas their collections of woody plants replenished and maintained.

The recent ecological situation of Kyiv megalopolis has a special specific of environment technogenic pollution as a chemical features and content of polluting phytotoxicants. During 2007–2012, our observation revealed what the most dangerous factors which have harm impact on the street woody plants are the huge concentration of phytotoxic elements (Na+, Cl-, Pb2+, Cd2+). Nowadays, the technogenic impact on the megalopolyisis surrounding comes to the dangerous, even, catastrophic level. The main reason of total and chloral necrose of leaves, the summer defoliation of crown and major tree's death is the over pollution of the soil and plant's phytomass by phytotoxic elements, the concentration of which by standards evaluation and by trees reactions are critical and exists at the level of adaptation possibility and survival. The main sources of Pb2+ and Cd2+ ions are transport outcomes (> 90 % of total technogenic pollution). The increasing of Pb2+ and Cd2+ in the soil is depended from intensivity of transport outcomes, using of ethylated petrol, and location of trees along roads as well as from the trees species. Continuously increasing of number of cars at the city streets is accompanying with similar increasing of ions concentration. Thus, in the soil around root system of street woody plants, depending from their location along roads, the concentration of Pb2+ (moving form) is between 41,7 (I. Kudri str.) and 102,6 mg\kg of soil (Nauki avenue). It exceeds the maximum permissible concentration (MPC), which is 20,8–51,3 mg\kg of soil. Next, for Norway maple (Acer platanoides) the concentration of Pb2+ in the soil varies from 41,7 to 80,5 mg / kg of soil in the area of the root system and it is around 20,8–40,2 MPC. In the leaves of this tree it is 7,83–13,5 mg / kg of dry mass (MPC is 15,8–27,0). For the horse chestnut (Aedculus hippocastanum) at the Nauka avenue, the concentration of plumbum in the root is 13,4 mg / kg (MPC is 26,8), in the cortex – 17,7 mg / kg (MPC is 35,4), in leaves – 8,21 mg / kg (MPC is 16,4), which by the normative evaluation are the critical concentrations. The source of Na+ and Cl-, which is a new factor for Kyiv megalopolis, is irregular load of high concentrations of industrial salt NaCl into the environment, as a way against black ice in winter time, where the Na+ ions ( mobile form) is in the high concentrations in leaves (0,76 % for Norway maple (Acer platanoides) on the I. Kudri str., 1,28 % – small-leaved linden (Tilia cordata) at the 40-richya Zhovtnya ave, 2,0 % – horse chestnut (Aedculus hippocastanum) at the Nauki ave), those are exceeded the concentration of the element comparing to the control test object, respectively, in 10,6, 12,8 and 5,0 times. Na+ ions are an aggressive phytotoxins and the main factor of leaves necrose of tree crown (within 70–100 % necrosis leaves in the crown). Degradation and total reduction of the specific weight of plants in the megalopolis environment are decrease the cleaning role of the street tree plants, which are the main alive filters for soil and air cleaning, as well as the main bioaccumulators and detoxicants of harm substances of anthropogenic pollution. Species adaptive specificity is revealed at the bioaccumulation level and the selective locality of phytotoxic elements (Na+, Cl-, Pb2+, Cd2+, agile form) in technourbanhabitats-pic conditions, there dominated bioaccumulation and localization of Na+ ions by trees assimilative system is caused the adaptive orientation of endogenic and intraspecific variability of phytoindicative morphophysiologic features of plants functional condition under the stressing factors. This also is defined the sensitivity of small-leaved linden (Tilia cordata Mill.), norway maple (Acer platanoides L.) and horse chestnut (Aesculus hippocastanum L.) to the big concentration of potassium as the most danger one for the plant survival. The biggest accumulation of Na+ ions at the roots of Lombardy poplar (Populus pyramidalis Roz.), Bolle's poplar (Populus bolleana Lauche) and sugar maple (Acer saccharinum L.) is lead to a higher resistance of their assimilation system. At the technourbohabitate-pic conditions, the level of realization of ontogenetic and phylogenetic adaptive capacity of the sensitive species of trees is harmfully low (21,3–44,3 %). It is at the level of survival/death of plants. The street Lombardy poplar, Bolle's poplar and sugar maple, despite of more higher level of their adaptation (68,4–87,7 %), still also can't fully adapt to the critical levels of technogenic pollution of megalopolis environment.

We provide a synthesis of all mammal taxa described from the African mainland, Madagascar and all surrounding islands in the 20 years since 1988, thereby supplementing the earlier works of G.M. Allen (1939) and W.F.H. Ansell (1989), and bringing the list of African mammals described over the last 250 years current to December 2008. We list 175 new extant taxa, including five new genera, one new subgenus, 138 new species and 31 new subspecies, including remarks, where relevant, on the current systematic position of each taxon. Names of seven species of primates are emended, according to the requirements of the ICZN. The taxonomic group in which the largest number of new taxa has been described is the Primates, with two new genera, 47 new species and 11 new subspecies, while geographically the biggest increase in new species descriptions has been on the island of Madagascar, accounting for roughly half (67) of all new species described in the past 20 years. Nearly half of all new species listed currently are assessed as Data Deficient on the IUCN Red List of Threatened Species (49 of 101 listed species) suggesting further research is urgently needed to help clarify the status of those recently described species.

Abstract Selected forestry parameters were investigated in the system of tree vegetation and wood-destroying fungi in parks of the Kyiv city along a gradient of recreational transformation. We investigated vitality, age structure and health conditions of woody plants (Acer platanoides L., Aesculus hippocastanum L., Carpinus betulus L., Frangula alnus Mill., Pinus sylvestris L., Quercus robur L., Q. rubra L., Sambucus nigra L., Tilia cordata Mill.), and species, systematic, trophic and spatial compositions of xylotrophic fungi (27 species of xylotrophs representing 22 genera, 16 families, 6 orders of divisions Basidiomycota; class Agaricomycetes). The results showed that the communities of tree vegetation and xylotrophic fungi in parks depend on the degree of recreational transformation of the environment. Vitality, age structure and health conditions of trees altered species composition of xylotrophs.

Abstract The mammal family Tenrecidae (Afrotheria: Afrosoricida) is endemic to Madagascar. Here we present the conservation priorities for the 31 species of tenrec that were assessed or reassessed in 2015–2016 for the IUCN Red List of Threatened Species. Six species (19.4%) were found to be threatened (4 Vulnerable, 2 Endangered) and one species was categorized as Data Deficient. The primary threat to tenrecs is habitat loss, mostly as a result of slash-and-burn agriculture, but some species are also threatened by hunting and incidental capture in fishing traps. In the longer term, climate change is expected to alter tenrec habitats and ranges. However, the lack of data for most tenrecs on population size, ecology and distribution, together with frequent changes in taxonomy (with many cryptic species being discovered based on genetic analyses) and the poorly understood impact of bushmeat hunting on spiny species (Tenrecinae), hinders conservation planning. Priority conservation actions are presented for Madagascar's tenrecs for the first time since 1990 and focus on conserving forest habitat (especially through improved management of protected areas) and filling essential knowledge gaps. Tenrec research, monitoring and conservation should be integrated into broader sustainable development objectives and programmes targeting higher profile species, such as lemurs, if we are to see an improvement in the conservation status of tenrecs in the near future.

SummaryTimneh Parrots Psittacus timneh are a threatened species endemic to the moist forests of West Africa. In 2016, they were categorised as ‘Endangered’ on the IUCN Red List, due to suspected rapid population declines driven by habitat loss and heavy trapping for the pet trade. Systematic assessments of the status of populations are lacking for much of their range and addressing this knowledge shortfall has been identified as a priority action. We combined multiple research approaches to investigate the distribution, trends and threats to Timneh Parrots in Guinea Bissau, where the species is restricted to the islands of the Bijagós archipelago and Pecixe. Direct observational surveys were conducted along line transects on 19 islands. A total of 69 groups were observed on eight of these islands, with the majority (78%) seen on just two islands. Forty-two interviews were conducted with local community members on 24 islands. Interviewees reported the species to occur on 20 islands and that populations are generally perceived to have declined in recent decades. Based on these findings and existing data we conclude that Timneh Parrots occur on 22 of the 32 islands considered and estimate the national population in Guinea-Bissau to be in the order of several hundred individuals, with perhaps half of the parrots occurring on the islands of João Vieira and Meio. Investigations into the factors linked to inter-island variation in parrot densities indicate that densities are highest on the islands which are most remote from permanent human settlements. These findings suggest that human activities including habitat modification and trapping have been important in driving population declines in Guinea-Bissau. We consider the implications of these findings for the conservation of Timneh Parrots.

The Action Plan for Australian Birds 2010 is the third in a series of action plans that have been produced at the start of each decade. The book analyses the International Union for Conservation of Nature (IUCN) status of all the species and subspecies of Australia's birds, including those of the offshore territories. For each bird the size and trend in their population and distribution has been analysed using the latest iteration of IUCN Red List Criteria to determine their risk of extinction. The book also provides an account of all those species and subspecies that are or are likely to be extinct. The result is the most authoritative account yet of the status of Australia's birds. In this completely revised edition each account covers not only the 2010 status but provides a retrospective assessment of the status in 1990 and 2000 based on current knowledge, taxonomic revisions and changes to the IUCN criteria, and then reasons why the status of some taxa has changed over the last two decades. Maps have been created specifically for the Action Plan based on vetted data drawn from the records of Birds Australia, its members and its partners in many government departments. This is not a book of lost causes. It is a call for action to keep the extraordinary biodiversity we have inherited and pass the legacy to our children. 2012 Whitley Award Commendation for Zoological Resource.
