Summary: This study describes the fossils of Ichthyopterygia reptiles found in the early Spathian stage in South Primorye, Russian Far East. The fossils represent a basal ichthyopterygian and a humerus of an ichthyopterygian, suggesting rapid diversification and high aquatic adaptation in Ichthyopterygia after the end-Permian mass extinction.

Summary: This paper discusses the Barremian-Albian stratigraphy of Sikhote-Alin and northeastern China, where the former is mainly marine deposits while the latter is mainly non-marine often intercalated with volcanic rocks. The paper also highlights the importance of sedimentary basins in both regions for non-marine and marine correlation.

Summary: Upper Mesozoic rocks are widely distributed in Sikhote-Alin in the Russian Far East and northeastern China, but they exhibit different characteristics in terms of marine and non-marine deposits. Despite the complex geological structure and different types of sedimentary basins in these regions, difficulties exist in establishing correlation schemes.

Summary: Insect pollination is a characteristic of flowering plants. Fossil records show that insects with elongate siphonate mouthparts, similar to those seen in present-day nectarivorous beetles and hymenopterans, existed long before the flowering plants. These insects most likely used their proboscis to obtain pollination drops and sugary fluids from cones of extinct gymnosperms. A recent discovery in Russia of long-proboscid holometabolous insects from the Early Permian provides evidence of a pollination mutualism with gymnosperms, suggesting that the complex interactions between pollinators and gymnosperms predates the first flowering plants by over 100 million years.

Summary: Information on the latest early Olenekian (latest Smithian) ammonoids is primarily available from seven regions worldwide, including South Primorye. Evidence of the latest Smithian period is recorded in areas such as West SMID, East SMID, and Golyj Cape in South Primorye, providing additional data on systematic composition and assemblages within the Shimanskyites shimanskyi Zone.

Summary: Two newly discovered clusters of Mycobacterium tuberculosis strains of the early ancient sublineage of the Beijing genotype have emerged in the Asian part of Russia and are strongly associated with MDR/XDR. In murine model and in vitro growth experiments, the 396 strain from Buryatia, Far East, showed higher virulence, while the 6691 strain from Omsk, Siberia, exhibited lower virulence. Further study of the highly lethal MDR strain 396 representing the Beijing 14717-15 cluster in Russia is warranted.

Summary: This study describes two brachiopod assemblages from the South Primorye area of Far East Russia, collected from the Barabash and Pilnikov sections. The Barabash assemblage shows a mix of Boreal Realm and Cathaysian Province elements, along with genera with antitropical distributions, indicating it might have been located in the Sino-Mongolian seaway in the northern temperate confluence of warm- and cold-water ocean currents.

Summary: This study analyzed the shell-size changes in bivalve fossils from South China during the end-Permian mass extinction and Early-Middle Triassic recovery. The results showed a significant reduction in shell size immediately after the extinction event, followed by a quick rebound and growth in the late Griesbachian. The variations in bivalve size were mainly influenced by factors such as competition, predation, and climatic and oxygen changes.

Summary: This study utilized multiproxy data from sediment cores retrieved from Lake Rauchuagytgyn in Arctic Russia to reconstruct the environmental history and ecological development of the lake over the past 29,000 years. The study found a strong correlation between diatom species abundance and the accumulation rates of organic carbon and mercury in the lake sediment. It also suggested that natural lake ecosystems can serve as long-term sinks for CO2 and mercury during warm climate episodes, highlighting the importance of maintaining intact lake ecosystems for future environmental policy.

Summary: The Epilchik Ural-Alaskan type complex contains lode platinum mineralization with a primary PGM assemblage typical for such complexes. The Snegovaya River hosts placer platinum-group minerals occurrences with comparable PGM assemblages to the lode chromitites, but with a higher mineral diversity. Both lode and placer mineralization indicate the Epilchik complex as the dominant source, with a larger diversity of PGM in placers possibly due to unsampled or unexposed outcrops.

Summary: With the increasing production of silver nanoparticles (AgNPs), it is important to understand their toxicological effects on different ecosystems. This study predicted the toxicity and bioaccumulation of AgNPs and silver nitrate in a marine bioindicator species. The results showed a higher toxic potential of silver nitrate compared to AgNPs, and a more efficient bioaccumulation of silver nitrate, 5 nm AgNPs, and 50 nm AgNPs.

Summary: The Russian Far East region has diverse climates, with the south influenced by monsoons and the north affected by the Arctic Ocean and cold air masses. Increasing economic activities and transportation linked to China's Belt and Road Initiative, coupled with climate change, are putting pressure on the environment in the region. Improving measurement capabilities for atmospheric and environmental pollution is urgently needed, along with integrated observations to support decision-making processes.

Summary: The new study reveals widespread post-subduction felsic magmatism from the middle Paleocene to early Eocene in the Sikhote-Alin territory, aligning with previous observations in Northeast China, the southern Korean Peninsula, and Japan. This igneous activity is associated with strike-slip tectonics and the termination of accretionary prism development, indicating a shift in tectonic regime from oceanic plate subduction to parallel sliding along a transform continental margin. These findings challenge the current tectonic model of Izanagi-Pacific ridge subduction beneath the East Asian continental margin.

Summary: The paper discusses the abundance, diversity, and extinction of non-marine algae in the Permian and Triassic periods, focusing on the aftermath of the end-Permian extinction interval. It also provides insights into the global biotic crises within the Permian-Triassic interval and the fossil records of non-marine algae in Gondwana. Finally, the review highlights the scarcity of quantitative fossil evidence for non-marine algae during these critical periods in evolutionary history.

Summary: The Siberian Traps volcanism is believed to be the main cause of the end-Permian mass extinction. Research on the Permian-Triassic transition in the Kuznetsk Basin in Russia shows that the biodiversity turnover occurred earlier in this area compared to South China, and the biota diversified rapidly towards the end of the Permian. The pattern of extinction, turnover, and diversity during the Permian-Triassic event was more complex than previously thought in different climatic zones and environmental habitats.

Summary: Non-marine bivalves from the Collio Formation and Guncina Formation in the Southern Alps are revised and described. The presence of these bivalves in the early-middle Kungurian period suggests a new center of origin and raises questions on biostratigraphy, paleobiogeography, and paleoecology.
