Most of the world's mountains are distributed across national boundaries. However, due to the sovereignty of national boundaries, conservation plans between neighboring countries are often uncoordinated. Against the backdrop of impending environmental changes, transboundary mountain ecosystems and biodiversity face significant threats. This study employs the MaxEnt model, leveraging data on climate, topography, landscape, and human activities to predict potential distribution areas for mammals and birds, aiming to identify biodiversity hotspots (BHs) and analyze their distribution mechanisms in the Altai Mountains transboundary region (AMTR). Results indicate that BHs are primarily located near the Russian-Mongolian border, significantly influenced by climate variables, elevation, and human activities. The study also highlights changes in key habitat types (KHTs), particularly transitions between grassland and bareland, and the impact of climate-driven land cover change on the distribution of BHs. Furthermore, the research evaluates the coverage of protected areas and emphasizes the importance of identifying key biodiversity areas (KBAs) and establishing transboundary corridors for enhanced species protection and future environmental change adaptation. The findings underscore the necessity of transboundary cooperation and focused strategies for biodiversity conservation to mitigate the adverse effects of climate change and human activities.
The Altai Mountains, spanning China, Russia, Kazakhstan, and Mongolia, are crucial habitats for many endemic, rare, and endangered species and are a vital migration corridor. However, the standards for establishing protected areas (PAs) differ among the four countries, resulting in suboptimal spatial arrangements and protection gaps in PAs. Therefore, here, by integrating the habitats of rare and endangered species and key ecosystem service areas, we identified potential conservation areas in the Altai Mountains. And we overlaid them with existing PAs in China, Russia, Kazakhstan, and Mongolia to determine the core habitats of the transboundary ecological networks for conservation. The identified core habitats covered 168,729.00 km2, representing 50.63 % of the Altai Mountains. Among these, potential conservation area not covered by existing PAs was approximately 82,833.50 km2 (24.86%). Additionally, 116 ecological corridors were identified with an average length of 38.15 km, including 8 transboundary corridors that connect the core conservation areas across different countries. Based on these findings, new PAs and other effective conservation measures (OECMs) in the Altai Mountains were proposed, along with a phased cooperation framework to gradually enhance the construction of transboundary ecological networks for conservation. Establishing the Altai Mountains’ transboundary ecological networks for conservation has the potential to become a model for transboundary conservation projects, providing valuable insights and guidance for developing conservation and collaborative management strategies in other transboundary regions.
The Highlands of Mongol Altay comprises three protected areas that represent a sequence of altitudinal vegetation zones from steppe, mixed forest, subalpine to alpine vegetation. The sites are important habitats for rare or endangered animal species such as the snow leopard, argali sheep, ibex and lynx. The Mongolian Altay also includes archaeological remains of nomads and their empires different periods in history
Political boundaries often do not coincide with ecological boundaries, and it is common for the same physical geographical unit to span multiple countries. Exploring establishing transboundary protected areas and ecological networks can effectively protect the integrity of natural ecosystems separated by political boundaries. Based on the integrated evaluation of ecosystem services function, ecological vulnerability, and ecosystem integrity, this study explored a methodological system for evaluating ecological protection priority areas in transboundary areas and selected the Altai Mountains, which span four countries, contain China, Kazakhstan, Russia, and Mongolia, as a typical case to conduct empirical research. The study found that the extremely important areas of ecosystem services function, ecological vulnerability, and ecosystem integrity showed transboundary contiguous characteristics. Furthermore, weighted overlay analysis identified the spatial distribution pattern of ecological protection priority areas in the Altai Mountains. We suggested establishing transboundary protected areas in the four countries' transboundary areas, building the identified ecological protection priority areas and existing protected areas into a transboundary protected area network, and deepening a multi-party transboundary protection cooperation mechanism. This study can provide a theoretical and practical reference to achieve the 2030 biodiversity conservation goals.

Mongolia is rich in medicinal plants. In recent years, interest in plant-derived food additives has grown. Many Lamiaceae species have a characteristic scent or taste, which in many cases are the reason for their application in Mongolian traditional medicine. This study was aimed to evaluate antioxidant, cytotoxic activities of aerial parts ethanol extracts from Nepeta sibirica L. grown in Mongolia. The antioxidant and cytotoxic activities of the essential oil and ethanol crude extracts were determined by using DPPH and MTT assays. The ethanol extracts showed higher antioxidant activity than essential oil. The results clearly showed that the essential oil presented satisfactory cytotoxic activity against two human tumor cell lines HepG2 (human liver cancer cell line); AGS (human stomach cancer cell line). Our work revealed that the ethanol extracts and essential oil of Nepeta sibirica L. grown in Mongolia has potential as sources of new antioxidant, and cytotoxic compounds, respectively.
