This paper addresses the ecosystem characteristics, biodiversity, conservation priorities, current threats and sustainable management of Khar Yamaat Nature Reserve, which lies in northeastern Mongolia. The formation of Khar Yamaat’s ecosystem and its biological diversity are unique in eastern Mongolia. Biogeographically, this nature reserve is located at the intersection between different phytogeographical regions, specifically the Central-Khalkh dry steppe, Mongol-Dahurian forest-steppe, and Eastern-Mongolian tall-grass steppe. As such, this nature reserve is home to a diverse complement of plants and animals representing the various ecoregions, was established in 1998 to protect 50,691 hectares of rocky-mountains surrounded by vast steppes. Khar Yamaat’s unique geological formation and assemblage of ecosystems have, since then, become an area of focus for environmental restoration and a center for research and monitoring. In general, the habitats of the nature reserve were found to be largely intact, if stressed to varying degrees, but wildlife populations appeared to be low. Anthropogenic influences, particularly heavy grazing by livestock, have threatened some species of vascular plants with extinction and reduced the abundance and distributions of a few other species. Serious threats included excessive or illegal take of plants and animals, overgrazing by livestock, human caused wildfires, climate change and associated drought, and mining in the buffer zone. In this paper, we discuss issues of conservation and sustainable management of Khar Yamaat Nature Reserve.

The study of the nature reserve oak forest near the village of Pelya-Khovanskaya ecosystem was done in the region of Nizhny Novgorod. The investigated wood is unique for its complex structure. It is situated in the forest-steppe zone, characterized by a high species diversity of small mammals and vegetation, which indicates the complexity of trophic and spatial connections. Several series of sample plots were described: 41 of 2020 m and a number of 11 m sites, totaling 300. Abundance of species by Brown-Blanke scale and the number of specimens of adolescence were specified for each 1 sq. m. plot. Mammals were trapped with the help of trapping grooves and transects method. Vegetation cover is characterized by the presence of a clear intra-differentiation as well as the existence of two basic ecologo-coenotic groups/cores - the nemoral (with Pulmonaria obscura Dum. as the center species of the core) and the meadow-fringe. The most distinct group is formed by forest-shoot species. It can be explained by more forest-steppe rather than nemoral nature of vegetation. Small mammals are represented by the following species: common and small shrews, small forest mouse, yellow-throated and field mice and harvest mouse, vole-housekeeper, common, plowed and red voles, European mole. Two species among them - vole-housekeeper and mouse-baby - are listed in the Red Book of the Nizhny Novgorod Region. Matching burrows of mouse-like rodents with soil richness with nitrogen and humidity, two well-defined peaks are observed. The greatest number of burrows is found in places where the soil is high in nitrogen. Moles were found in areas with a large projective coating of Primula veris: coefficient Spearman rank 0,50. There was a negative correlation of the number of moles and vegetation covering of Pyrethrum corymbosum (-0,46), which is the marker of the driest parts in the forest. In general, the nature reserve oak forest near the village of Pelya-Khovanskaya is of considerable interest, both from botanical and from zoological point of view. Long-term studies of biocoenosis will allow to monitor the facility and to correct the proposed protective measures.

The aim of the study was to assess the resource role of flowering woody plants in maintaining the biological diversity of insects. The studies were carried out in 2019–2020 in the northern forest-steppe of the Ob region during the flowering period of woody plants from the Oleaceae family of the genus Syringa: S. josikaea J. and S. vulgaris L. Insects were collected by mowing with an entomological net in the crowns and under-crown space. The flowering of plants attracted insects from more than 25 families from 7 orders. The largest number of insects belonged to the order Thysanoptera 79.2%, followed by representatives of the orders Hemiptera (7.1%) and Diptera (6.4%). The entomological faunas of S. josikaea and S. vulgaris differed significantly in their taxonomic composition, insects abundance, and their association with flowering periods. Low coefficients of similarity and high power of the factor “plant species” influence on biological diversity and the insects number were revealed. S. josikaea played a more significant role in maintaining the biological diversity of insects. Research showed that insects are associated with a certain species of woody plant.

The aim of the study was to determine the influence of plant species and year conditions on the biological diversity and number of insects – inhabitants of the crown layer of woody plants of the Rosaceae family in the conditions of the northern forest-steppe of the Ob region. The research was carried out in 2017–2018. During the flowering period of woody entomophilous plants, insects were collected by mowing with an entomological net in the crowns and undercrown space (25 strokes in four repetitions). In the crown of woody introduced plants Pyrus ussuriensis (Ussuri pear), Prunus maackii (Maak plum), Amelanchier alnifolia (alder irga), Spiraea betulifolia (spiraea birch leaf), Physocarpus opulifolius growing on the territory of arboretum of RAS in the northern forest-steppe of the Ob region, a total of 2597 insect specimens from 7 orders and more than 30 families were found. The largest number of insects belonged to the order Diptera (49.4 %). Representatives of the orders Thysanoptera (23.7%) and Hymenoptera (11.4%) made a significant contribution to the formation of the entomofauna. The entomofauna of different species of woody plants from the Rosaceae family differed in the taxonomic groups of insects and their numbers. A high degree of enomofauna similarity (Jaccard coefficient is 0.75) was found between Amelanchier alnifolia and Pyrus ussuriensis with similar flowering periods. A low degree of similarity was found between Amelanchier alnifolia and Spiraea betulifolia (0.32) and between Pyrus ussuriensis and Physocarpus opulifolius (0.33). The species of the plant (38.1 and 26.1%, respectively) had the greatest influence on the biological diversity and the number of entomocomplexes, which indicates the adaptation of insects to a woody plant of the Rosaceae family. The conditions of the year significantly (by 9.8%) influenced the biological diversity of insects during the flowering period.

The study of biodiversity has received wide attention in recent decades. Biodiversity has been defined in various ways (Gaston and Spicer, 1998, Purvis and Hector 2000, and chapters in this volume). Discussion regarding its definitions is dynamic, with shifts between the more traditional emphasis on community structure to emphasis on the higher ecosystem level or the lower population levels (e.g., chapters in this volume, Poiani et al. 2000). One of the definitions, proposed in the United Nations Convention on Biological Diversity held in Rio de Janeiro (1992) is “the diversity within species, between species and of ecosystems.” The within-species component of diversity is further defined as “the frequency and diversity of different genes and/or genomes . . .” (IUCN 1993) as estimated by the genetic and morphological diversity within species. While research and conservation efforts in the past century have focused mainly on the community level, they have recently been extended to include the within-species (Hanski 1989) and the ecosystem levels. The component comprising within-species genetic and morphological diversity is increasingly emphasized as an important element of biodiversity (UN Convention 1992). Recent studies suggest that patterns of genetic diversity significantly influence the viability and persistence of local populations (Frankham 1996, Lacy 1997, Riddle 1996, Vrijenhoek et al. 1985). Revealing geographical patterns of genetic diversity is highly relevant to conservation biology and especially to explicit decision-making procedures allowing systematic rather than opportunistic selection of populations and areas for in situ protection (Pressey et al. 1993). Therefore, studying spatial patterns in within-species diversity may be vital in defining and prioritizing conservation efforts (Brooks et al. 1992). Local populations of a species often differ in the ecological conditions experienced by their members (Brown 1984, Gaston 1990, Lawton et al. 1994). These factors potentially affect population characteristics, structure, and within-population genetic and morphological diversity (Brussard 1984, Lawton 1995, Parsons 1991). The spatial location of a population within a species range may be related to its patterns of diversity (Lesica and Allendorf 1995). Thus, detecting within-species diversity patterns across distributional ranges is important for our understanding of ecological and evolutionary (e.g., speciation) processes (Smith et al. 1997), and for the determination of conservation priorities (Kark 1999).

Recently, much attention has been paid by scientists from different countries to the issues of tourist environmental management. The kumis therapy development, being a historically established direction of medical tourism, is promising in the steppe regions. When analyzing the history of the development of kumis therapy in the former USSR, it was revealed that after the collapse of the USSR, an organized network of kumis treatment centers ceased to exist. Original maps reflect historical aspects and modern geography of sanatorium with kumis treatment. Most of them are located in the forest-steppe and steppe zones. The paper considers the steppe region of Russia the Orenburg region promising for the development of kumis treatment in connection with a suitable dry steppe climate, the development of horse breeding and the possibilities of landscape therapy. The paper notes the appropriateness of the further development of kumis treatment and the modernization of kumis treatment centers in the Orenburg region.

Rapid Economic Growth

The ecosystem of health and natural resource management is influenced by the social, political, economic system and institutional framework in a region. Rapid economic growth in Bangalore and its environs in recent decades has resulted in environmental changes in Bannerghatta National Park (BNP) and its buffer (of 5 km). Land use land cover (LULC) change analysis with a modelling technique such as cellular automata (CA)-Markov was used for quantitatively exploring forest cover transitions. The analysis of LULC dynamics has revealed loss of vegetation cover from 85.78 per cent to 66.37 per cent (1973–2015) and severe environmental stress. The region has lost moist deciduous cover, from 26.1 per cent to 13.8 per cent, and witnessed an increase in horticulture, from 8.5 per cent to 11 per cent (1973–2015). The visualization of likely land use in 2027 indicates the loss of forest cover from 41.38 per cent to 35.59 per cent with an increase in urban area from 4.49 per cent to 9.62 per cent (with new residential and commercial layouts in the buffer zone of BNP in violation of the eco-sensitive zone norms as per Section 5(1) of Environment Protection Act 1986). The study provides insights for developing an appropriate planning framework towards conservation and the sustainable management of ecologically sensitive national parks.

We reported a complete check-list of Vertebrates for the “Tenuta dei Massimi” nature reserve, a protected area well representing a remnant agro-forest heterogeneous mosaic landscape of the “Campagna Romana”. Data were obtained from a large original and bibliographic data-set on a large time-span (1991-2012). This reserve represents an area with a high value of species richness when compared to the surrounding metropolitan areas, also including a large number of species of conservation concern at different scales. We obtained evidences for the occurrence of 141 species (one fish, six amphibians, 12 reptiles, 101 birds, 21 mammals). Among them, some species are of conservation concern at European, regional or local scale. Further research should be focused on a set of fragmentation-sensitive species to verify the long-term viability of their local small populations [<em>e.g. Hyla intermedia</em> Boulenger, 1882, <em>Bufo lineatus</em> Ninni, 1879, <em>Muscardinus avellanarius</em> (Linnaeus, 1758), <em>Sorex samniticus</em> Altobello, 1926)].
