The collection fund of rowan trees of the Mountain Botanical Garden, located at an altitude of 1700 m above sea level (Gunib plateau), includes 30 species, 5 varieties, cultivars and hybrid forms. There are 6 species of rowan in Dagestan, introduced from natural habitats, of which three species are included in the Red Book of Dagestan, and are included in the Red List of Endemic Species of the Caucasus (IUCN). As a result of the search and research work, new locations of four rare and endangered species of rowan ( S. caucasica, S. graeca, S. kusnetzovii, S. subfusca ) that are threatened with extinction in Dagestan were identified. The geographical coordinates of the exact location of rowan species are marked, and maps of the species' range on the territory of the Republic of Dagestan are compiled. For further monitoring observations, the total number of species was clarified, the biomorphological indicators and the age structure of the populations were studied. Under the conditions of culture, they were propagated by seeds and vegetatively by grafting on the rootstock of S. aucuparia .

The high mountainous beech (Fagus orientalis) forests of Dagestan which are a refugium of the species with oceanic/suboceanic distribution in the arid conditions of the East Caucasus have been studied for the first time, and 140 species of lichens, lichenicolous and non-lichenized fungi growing on beech have been revealed. Among them 3 species (Leptogium burnetiae, Lobaria pulmonaria, and Ricasolia amplissima) are endangered lichens included in the red data book of Russia. Seven species (Abrothallus nephromatis, A. peyritschii, Biatora beckhausii, Biatoropsis usnearum, Bryoria vrangiana, Dactylospora lobariella, and Usnea fragilescens) and 2 genera (Biatoropsis and Ramonia) are reported for the first time for the East Caucasus; 10 species (Collema nigrescens, C. subnigrescens, Gyalecta fagicola, G. herculina, Lecanora intumescens, Leptogium burnetiae, L. cyanescens, Melanohalea elegantula, Nephroma helveticum, and Ramonia luteola) and the genus Biatora are new for Dagestan. The record of Ramonia luteola is the second for Russia and the Caucasus. Most of the lichens are with trebouxioid photobiont, cyanolichens are represented by 20 species, lichens with trentepohlioid photobiont — by 14 species. Reproductive strategy by spores is prevailing. Vegetative diaspores are formed by 51 species of which 46 are fruticose and foliose. The species from Lobarion pulmonariae community are revealed. The presence of rare and endangered species shows a high value of studied community for nature protection.

Introduction Experiment

Species and cultivars of the genus Allium L., family Alliaceae occupy a significant place is in the collection of floral and ornamental herbaceous perennials of the Stavropol Botanical Garden. The first supplies of plants to the exhibition areas of the garden took place in 1962. Nowadays, 34 taxa grow in the collection of herbaceous perennials. Research work on the study of local species and introduced species has been carried out since 2010. In 2020, the results of an introduction experiment to study the seasonal rhythms of plant growth and development, their ecological growth conditions, biomorphological indicators, decorative qualities, and economically valuable features, resistance to adverse weather conditions, pests, and diseases were summed up. Analyzing the data obtained, the author identifies the most promising species and cultivars for the introduction on the territory of the Stavropol upland in the conditions of a sharply continental climate and the zone of unstable moisture. As a result of the final assessment of the adaptive features of bows and their decorative qualities, the following groups were identified: very promising – 21, promising – 7, and unpromising – 6. The research team suggests using highly decorative and decorative species, resistant to cultivation in Stavropol and other localities in the region, in practical floriculture. Low-promising and low-decorative ones are valuable species and cultivars used in medicine or consumed as food and rare and endangered species of the Russian Federation 28 and neighboring countries. Plants of the genus Allium in the collection of the Stavropol Botanical Garden are a scientific base for holding regional environmental seminars for schoolchildren and students of higher educational institutions. Acquaintance with this group of plants is of great interest for landscape design specialists and amateur flower growers.

Impact On Biodiversity

The purpose of this study is to explore the biodiversity reporting practices inside Indian companies. Biodiversity reporting studies across Indian companies are important because India has a wealth of biodiversity assets, that is, wildlife, flora, fauna, natural habitats, rare and endangered species and biological resources, and accounts for 7.8% of the global recorded species (Biological Diversity Act, the Biodiversity Rules, Andhra Pradesh Biodiversity Board, 2009). There are approximately 45,500 species of plants, 91,200 species of animals and 5,550 microbial species documented in India (National Biodiversity Authority, 2014). The International Union for the Conservation of Nature (IUCN) has listed 132 species of animals and plants in the Critically Endangered Category (Sudhi, 2012). To date, the literature omits to explore the biodiversity reporting practices inside Indian companies. Another important reason to conduct is this study is that India has alarming population levels; thus there is a huge demand for land, energy, and resources, which leads to massive biodiversity loss, deforestation, and habitat destruction. It is very likely that with the limited land mass and increasing population in India, several ecosystems, wildlife, flora and fauna will be/have been exploited, disturbed, and endangered. Given the high potential impact on biodiversity by industries, we are concerned that there is a dearth of biodiversity reporting studies within the Indian subcontinent. We concentrate on the largest companies (based on market capitalisation) because similar to Van Liempd and Busch (2013), we also expect that the largest companies have the greatest impact on biodiversity; therefore, they are expected to show more accountability to their stakeholders. Therefore it is worth exploring how Indian companies are engaging in biodiversity reporting practices (e.g. biodiversity conservation, biodiversity protection, habitat and ecosystem conservation); and whether these organisations are disclosing their impact(s) (both in quantity and quality) on biodiversity (such as wildlife, flora and fauna). Moreover, India has also been classified as one of 17 mega-diversity countries by The World Conservation Monitoring Centre which account for more than 70% of the planet’s species (Williams, 2001). All these reasons make this study timely and important.

Abstract. The article presents the results of an experimental assessment of the peculiarities of the water regime of 9 species of the genus Iris L. growing in the South-Ural Botanical Garden-Institute UFRC RAS (I. sibirica L., I. pseudacorus L. ‒ species of native flora, I. aphylla L., I. biglumis Vahl., I. lacteal Pall., I. orientalis Mill., I. ruthenica Ker-Gawl., I. setosa Pall., I. spuria L. ‒ introduced species). The purpose is a comparative evaluation of the main parameters of the water regime within the generic complex and depending on the detection of meteorological factors in different phenological periods. Methods. Studies were performed in growing periods 2019–2020’s physiological using conventional techniques (artificial saturation method and wilting). Made a detailed analysis of daily and seasonal dynamics of the water regime of the three parameters: the total water content, water-holding capacity, water scarcity. Typical forest species Convallaria majalis L. was investigated for a comparative analysis of water regime indicators. Results. The similarities and differences in the peculiarities of the water regime were established between the studied species, the dependence of the indicators on meteorological conditions was revealed. According to the type of water regime cultivars were divided into four groups: a flexible water-quiet mode ‒ I. pseudacorus, flexible water-tight mode ‒ I. sibirica, I. ruthenica, stably-calm water mode ‒ I. aphylla, I. biglumis, I. setosa, stably-tight water mode ‒ I. spuria, I. lactea, I. orientalis. Among the studied parameters of water scarcity was the most dependent on meteorological factors. Scientific novelty. The study helps to identify ecological and physiological adaptations of exotic species in comparison with the native species that could become the basis for assessing the prospects of growing in the culture and conservation of rare and endangered species.

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.

The goal of this study was to detect endopolyploidy of Ligularia sibirica from populations existed in different ecological conditions. This is important step to elaborate the appropriate protection measures of rare and endangered species, which should be based on understanding of ongoing processes in populations. From this point of view the knowledge of genetic diversity, including endopolyploidy level between and within populations, is crucial. L. sibirica is endangered and protected plant species in Latvia which is included in the protected plants list of EU Habitat directive 92/43/EEK Annexes 2 and 4. Perennial herbaceous plant L. sibirica is one of two species of genus Ligularia in Europe. According to the previous data, this species has been disappeared from all previously known locations in Latvia. However, some new locations were found in central part of the country recently. Determination of edopolyploidy level of L. sibirica was performed by the BD FACSJazz® cell sorter (BD Biosciences, USA) with flow cytometer function. In young leafs nine relative fluorescence DNA peaks from 2C up to 64 C were detected. The most common was 2C peak presented in 93% and 63% of samples from Zušu-Staiņu sulphur spring and Krustkalni Nature reserve populations respectively.

The article presents an analysis of chromosome numbers in Siberian species of the genus Viola (40 speciesfrom 12 sections) based on numerous literary sources and original data. In addition, hybrid forms from the collection site“Rare and endangered Plant Species” of the Central Siberian Botanical Garden (Novosibirsk) were analyzed. Just as theroots of germinated seeds, so the roots of adult plants from an open ground area were studied. Samples of different originswere investigated: Siberia, the Far East, Mongolia, Belarus, Korea, Japan, the Caucasus, in some taxa from remote points ofthe area (for example, V. selkirkii). This allowed us to reveal the variability of the chromosome numbers for some species.Chromosomes in species of this genus are small, 0.8–1.2 mkm long. This involves difficulties to count them. The presenceof mixoploids in some sections and the polybasic state of chromosome numbers for a number of species were established.Polymorphic species in the Violidum section are characterized by polyploid races. The variability of chromosome numbersin taxa reflects their ability to hybridize, as well as the processes of speciation. However, the predominance of autogamy formost species of the genus prevents intensive hybridization. Endemic and tertiary relicts are characterized by a stable number of chromosomes and they are tetraploids.
