The purpose of the research is to analyze the distribution, anatomical and morphological aspects of dryland mollusks found in the Central Uzbekistan region, and to provide information on their ecology, distribution, limiting factors, and conservation measures. The material collection was carried out according to the methodology of A.A. Shileyko. Based on the results of the collected research, it can be concluded that due to the necessity of moisture for mollusks in the ecological complex, they can be classified into three major groups: hygrophilous, mesophilous, xerophilous, and mesoxerophilous species. The research results indicate that out of the 7 species found in the Central Uzbekistan region, currently, 28.75% are classified as critically endangered, approximately 42.85% are considered vulnerable, and 28.75% are endangered. The dryland mollusk species found in the Central Uzbekistan region are categorized ecologically into hygrophilous, xerophilous, and mesoxerophilous types. In order to conserve and monitor the population of dryland mollusk species in the Central Uzbekistan region, it is recommended to first protect their habitats, particularly by halting deforestation and degradation of habitats where mollusks reside, secondly, to restrict extraneous use of these areas as pastures, and thirdly, to undertake research on their habitat preferences and biology to prevent their extinction as a species.

“…The Lower Zeravshan differs significantly in climatic conditions from the upper and middle parts of the Zeravshan Valley. The biodiversity of vegetation cover and its features of the Lower Zeravshan region has been well studied and it includes mainly xerohalophytic plants (Akhmedov et al, 2021;Bazarov et al, 2023). However, information about the fauna of invertebrate animals, especially beetles, is extremely insufficient.…”

The Lower Zeravshan district of Uzbekistan is characterized by the most arid climate and is particularly affected by global warming and anthropogenic pressure. The biodiversity of herpetobiont beetles in this region has not been sufficiently studied, and this makes it difficult to monitor the fauna of the region. This work was carried out to assess the biodiversity and ecological features of some groups of herpetobiont beetles during 2019–2023. Soil and light traps, soil excavations and manual collection were used to collect material. A total of 131 species of beetles were identified. The carabid fauna of the region is represented by 43 species belonging to nine subfamilies, 19 tribes, and 28 genera. For the fauna of the Republic, two species were recorded for the first time (Syntomus obscuroguttatus (Duftschmid, 1812) and Scarites subcylindricus Chaudoir, 1843). The darkling beetle fauna includes 46 species belonging to three subfamilies, 16 tribes, and 30 genera. For the first time, five species were recorded for the fauna of the Republic of Uzbekistan (Cyphogenia lucifuga Adams, 1817, Trigonoscelis apicalis Reitter, 1907, Colpotus sulcatus (Menetries, 1838), Tribolium destructor Uyttenboogart, 1933, Pentaphyllus chrysomeloides (Rossi, 1792)). The fauna of ground beetles and darkling beetles of the Lower Zeravshan consists of two species complexes that differ sharply from each other – xerophilic (inhabiting desert biocenoses) and hygromesophilic (inhabiting agricultural landscapes). The similarity coefficients of the fauna of these two types of biocenoses are very low. The fauna of click beetles is represented by 10 species belonging to four subfamilies and seven genera. The fauna of lamellar beetles consists of 31 species (32 with subspecies), belonging to eight subfamilies, 13 tribes, and 19 genera. In agrocenoses, a significant increase in the number of herpetobionts is observed in the first days of June. But their maximum number is observed in early July. It has been established that seasonal fluctuations in the number of representatives of the families Carabidae, Elateridae, Staphylinidae, and Tenebrionidae occur almost in parallel. Fluctuations in the number of representatives of the Scarabaeidae family do not correspond to the above pattern, and the maximum value is observed at the end of July. The data obtained can be used to assess biodiversity and environmental monitoring of arid zones of Uzbekistan.

“…Geographically, one third of the territory of Uzbekistan consists of mountains (Kudratov et al 2023). Sudden changes in the climate in the mountains, the large-scale impact of stress factors on the diversity of flora (Akramov et al 2023;Alikulov et al 2023;Bazarov et al 2023) and fauna (Nurullayeva et al2023;Narzullayev 2022;Khalimov 2023;Khalimov et al 2023;Narzullayev et al 2023) affected. In addition, there is a high possibility that this condition caused the grain quality indicators to differ among agricultural crops, including wheat varieties, which have been cultivated in the mountain region for a long time.…”

Abstract. Ruziyev F, Djabbarov I, Olimjonova S, Niyozov U, Urokov S, Ishankulova D, Bakhadirov U. 2023. Grain quality indicators and their phenotypic variability of ancient varieties of Triticum aestivum in the mountains of Uzbekistan. Biodiversitas 24: 5995-6001. Today, creation of varieties of agricultural crops that are resistant to adverse environmental factors and produce stable crops under the influence of stress factors has become one of the most important issues in the world. In the following years, scientific and research work is being carried out on the wide use of the diversity of its genetic resources in the creation of new varieties of wheat (Triticum aestivum L.). In this regard, there are opportunities to use wild, semi-wild and ancient local forms of wheat with high protein and high gluten content to create varieties that meet modern production requirements. Therefore, it is important to evaluate the quality indicators of ancient varieties and the degree of phenotypic variation in the selection of wheat varieties that are resistant to adverse environmental factors, fertile and high-quality. This research work, aimed at researching ancient wheat varieties cultivated by the people living in the mountainous regions of Uzbekistan for many years. According to the research results, the grain quality indicators (grain hardness, diameter of grains, grain quality indicators, rheological properties, etc.) of the ancient wheat varieties distributed in the mountain regions are different. According to the results of the experiment, the grain hardness of the studied ancient wheat varieties is 73-82 µm, grain diameter 2.65-2.71 mm, hectolitre of weight 818.2-838.1±8.7 g/L, vitreousness 62.2-70.3%, gluten content in grain 31.5-34.6%, sedimentation index 64.4-77.2 mL. It was also observed that the phenotypic variability of the quality indicators was different in the wheat varieties that were the object of the study. Differences in the grain quality indicators of ancient wheat varieties are explained by the different effects of climatic parameters, abiotic and biotic factors in the regions where wheat grows. The information presented in the article provides an opportunity to select ancient wheat varieties distributed in the mountainous regions of Uzbekistan as starting sources for the creation of varieties with high nutritional value, resistant to adverse factors.
