The purpose of the article is to study what traces of their stay the Kayi left in the &#13;
Orangay region of Kazakhstan. This study utilises a range of scientific research &#13;
methods, including descriptive, comparative, historical-critical, and dialectical &#13;
approaches, as well as methods of analysis and synthesis. The investigation reveals &#13;
that Orangay, situated within the Turkestan oasis and along a branch of the Great &#13;
Silk Road, played a crucial role in the history of the Kayi tribe during the VIII-XI &#13;
centuries. This region served as a focal point for the Oghuzes and witnessed the &#13;
emergence of the Oghuz State in the Aral Sea region and the lower reaches of the &#13;
Syr Darya. Orangay also marked the consolidation of the Kayi tribe, marking the &#13;
beginning of their ascendance. Archaeological excavations in the Turkestan oasis &#13;
provided concrete evidence of the direct connection between the Orangay region &#13;
and the Kayi tribe, including the discovery of pottery adorned with snake patterns, &#13;
characteristic of the Kayi tribe’s material culture. In conclusion, this research &#13;
establishes Orangay as a historically significant region for the Kayi tribe during the &#13;
VIII-XI centuries in Central Asia.

Pharmaceuticals are crucial for human health, but their release into the environment &#13;
through various means can contaminate groundwater, surface waters, soil, and &#13;
microorganisms. The contamination of water by pharmaceuticals in Kazakhstan is not &#13;
well-studied. Understanding the influence of pharmaceutical ingredients on the &#13;
ecosystem and public health is a key area of ecological research. Globally, researchers &#13;
are investigating the risks posed by pharmaceuticals in water sources and their &#13;
environmental effects. This study uses Chlorella sp. to test the impacts of &#13;
pharmaceuticals on aquatic biota, examining growth rate and growth inhibition. The &#13;
study followed OECD Research Method 201. Pharmaceuticals with high pollution &#13;
potential in Kazakhstan's water resources, including ketoconazole, terbinafine, &#13;
drotaverine hydrochloride, telmisartan, benzylpenicillin, and azithromycin, were studied. &#13;
Azithromycin was found to be the most toxic to Chlorella sp. (0.33 ± 0.05 mg/L), while &#13;
amoxicillin had the least toxic effect (853.54 ±0.27mg/L). Azithromycin has significant &#13;
effect to Chlorella sp. resistance, especially in smallest experimental concentrations. At &#13;
0.2 mg/L, azithromycin nearly halved the growth rate compared to the control, growth &#13;
inhibition was over 87% at 0.15 mg/L (r2=0.89). Chlorella sp.showed minimal sensitivity &#13;
to high concentrations of amoxicillin, with slight decrease of growth (2% at 1 mg/L, 57% &#13;
at 1000 mg/L).

This paper presents the results of microscopic analysis of a &#13;
perspective medicinal plant Helianthus tuberosus used for the treatment of &#13;
diabetes mellitus. The study was conducted to identify specific &#13;
morphological and structural characteristics of this plant, which may have a &#13;
positive impact on the efficacy and safety of its use for medical purposes. &#13;
Different types of plant material were used in the research: fresh plants, dried &#13;
plant material and preserved plant material. For preservation of the latter, a &#13;
special mixture consisting of ethyl alcohol, glycerol and distilled water in &#13;
equal volumes was used. Anatomical study of the structure and structure of &#13;
plants was carried out using several methods: to study the structure of the &#13;
epidermis, surface samples were prepared, which allowed us to get a detailed &#13;
idea of the cellular composition and location of the epidermis on the surface &#13;
of leaves, stems and roots of plants; for a deeper study of the internal &#13;
structure of plants, transverse sections were made, which were further &#13;
investigated. The results of the study suggest the high potential of this plant &#13;
as a basis for the development of safe and effective phytopreparations.

<title>The impact of climate aridification on rare lichen communities</title>

<description>The impact of climate aridification on rare lichen communities
Bukabayeva, Z.; Abiyev, S.; Silybayeva, B.; Ivachshenko, O.
The global diversity of approximately 25,000 lichen species (e.g., from the genera Usnea, Cladonia, and Peltigera), including &#13;
rare and endangered ones, highlights the importance of preserving their population in the State National Nature Park “Burabay”.&#13;
The objective of this study was to investigate the distribution of rare lichen species in the territory of the State National Nature Park &#13;
“Burabay,” located in the Akmola region of Kazakhstan, in the period from 2018 to 2022, with a particular focus on understanding &#13;
how aridification may have influenced their presence and abundance. In the course of the study, methods such as route expeditions, &#13;
the comparative morphological method, as well as some other special methods were used. The collection of information to systematize the taxonomic composition of lichens (genera Lobaria, Rhizocarpon, and Xanthoria) was carried out during route expeditions. &#13;
The study identified 56 lichen species, with a focus on rare and protected species. Established in 2000, the park's rich biodiversity is &#13;
showcased, including the discovery of three very rare species (Dermatocarpon miniatum, Psora lurida, and Verrucaria nigrescens) &#13;
and four species requiring protection (Peltigera spuria, Cladonia coccifera, Haematomma ventosum, and Caloplaca aurantiaca). &#13;
These findings are significant, considering the absence of data on these species since the 1982 Red Book of Kazakhstan (including &#13;
genera such as Lecanora, Lecidea, and Pertusaria). The sensitivity of lichens to environmental changes (indicated by genera like &#13;
Alectoria, Bryoria, and Cetraria) makes them ideal for monitoring ecological health through a cost-effective method known as lichen &#13;
indication. The increase in the species count over the past five years (highlighting genera such as Stereocaulon, Solorina, and Thamnolia) suggests effective conservation efforts and underlines the park's ecological importance. The study's findings reveal that aridification is reshaping lichen communities in the park, emphasizing their sensitivity to climate change and the need for conservation strategies to address these changes and ensure the preservation of lichen biodiversity in the face of global climate change. The research &#13;
contributes valuable data for future conservation planning and environmental assessments in the region, emphasizing the need to &#13;
protect diverse lichen genera (e.g., Evernia, Ramalina, and Parmotrema) for ecological monitoring and conservation.
