Summary: A new species of Cobitis, Cobitis indus, has been discovered in the Dalaman River drainage. It has distinct characteristics that differentiate it from other Cobitis species in the eastern Aegean Sea basin, as well as from its closest relative, C. dorademiri. The Dalaman River drainage now holds the record for the highest species diversity of spined loaches in the Middle East.

Summary: This study provides new data on the geochemistry of coal deposits in the Sakhalin Basin. It reveals that the coals in the Basin have concentrations of trace elements similar to the global average, with a geochemical assemblage typical for transition areas. The coals in the Basin are enriched in certain elements compared to the world average, and the ash contains rare alkali metals and other elements. The geochemical characteristics of coal-bearing sediments reflect the geological evolution of the Basin, with anomalies associated with the composition of surrounding rocks and hydrothermal activity.

Summary: Through a study of the Karasu River, it was discovered that there are three distinct populations of Euphrates trout, with two populations belonging to Salmo munzuricus and one population belonging to a newly named species, Salmo baliki. This new species has unique characteristics that differentiate it from other Salmo species in adjacent water bodies, as confirmed by genetic analysis of the Cyt b mitochondrial gene.

Summary: Increasing evidence suggests that lymphocytes play distinct roles in inflammation-induced tissue remodeling and tissue damage. Arteriogenesis describes the growth of natural bypasses from pre-existing collateral arteries. The role of innate immune cells is widely understood in the process of arteriogenesis, whereas the role of lymphocytes remains unclear and is the subject of the present study.

Summary: Genetic variation in the Tsushima salamander reveals two distinct populations, with a closer relationship to an unknown Hynobius species than to its own. Reproductive isolation between these populations was strongly indicated, marking the first documented occurrence of syntopic breeding of two lotic salamanders of the Hynobius genus on a small island. The independent acquisition of lotic breeding habits is proposed as a possible explanation.

Summary: A new strain of oogamous biflagellate green alga was discovered and classified as part of the RL clade within Oogamochlamydinia. It shares similarities with members of the genus Oogamochlamys but differs in certain cell morphology and structure features. Despite the doubts about its relation to Oogamochlamys based on phylogenetic analysis, the strain from Iturup Island is described as a new species, Oogamochlamys kurilensis.

Summary: Developing B cells generate DNA double-stranded breaks (DSBs) to assemble immunoglobulin receptor (Ig) genes necessary for the expression of a mature B cell receptor. RAG-mediated DSBs in pre-B cells activate the ATM kinase, coordinating canonical and non-canonical DDR and triggering DSB repair and B cell developmental signals. Unique properties of the RAG endonuclease regulate the distinct cellular responses to RAG DSBs in B cells.

Summary: This study examined the age, growth, and maturation of Coregonus ussuriensis individuals in the middle section of the Amur River, China. The study found no significant difference in growth between males and females, and the spawning season for Coregonus ussuriensis was mainly in November and December.

Summary: The study compared Cytb mtDNA sequences of different populations of two phytoseiid mite species to investigate genetic variations. Results showed higher genetic distances and differentiation in Phytoseiulus macropilis based on geographic location and pyrethroid resistance, while populations of P. persimilis were genetically similar, possibly due to their origin and commercialization. Protein analysis revealed no diagnostic mutation related to pyrethroid resistance, but identified mutations between populations of P. macropilis from different climatic regions. Further research is needed to understand the impact of these mutations.

Summary: This study investigated the changes in wetland vegetation cover and its responses to climate change in the Heilongjiang-Amur River Basin. The results showed an increase in wetland vegetation cover, with wetting and warming trends in the regional climate. The wetland vegetation in China and Russia had positive correlations with solar radiation and minimum air temperature, while the wetland vegetation in Mongolia had a positive correlation with precipitation. These findings contribute to a better understanding of the responses of wetlands in the middle and high latitudes to climate change.

Summary: This study examined the spatiotemporal characteristics of land cover in the Heilongjiang (Amur) River Basin using land-use change index, frequency statistics, and land-cover change degree. The results indicated that forest land and grassland were the predominant land-cover types, while urban land, cropland, and wetland areas increased significantly from 2001 to 2019. The findings contribute to ecological protection and sustainable development in the region and can be applied to similar land-cover change research.

Summary: This study generated an immunodeficient chicken model using CRISPR/Cas9 technology and revealed the pivotal role of RAG1 in avian-specific immune cell development. The model demonstrated the impaired B cell proliferation and disrupted B cell receptor-mediated signaling due to disordered Ig V(D)J recombination. Furthermore, this study also highlighted the dose-dependent regulatory role of RAG1 in immune cell development.

Summary: The study focuses on the identification of female artificial sturgeon hybrids capable of producing unreduced oocytes, with experiments showing the potential to obtain all-female clonal lines. The results provide insight into the possibility of developing a technology to produce all-female offspring, which could have implications for experimental reproduction of reticular speciation in nature.

Summary: This study analyzed the population genetic structure of the endangered freshwater fish species Cobitis vettonica in the Iberian Peninsula and explored its relationship with its sister species Cobitis paludica. The results highlight the role of hydrogeomorphological processes and climatic changes in shaping the population structure of C. vettonica and its relationship with C. paludica. The study also identified the threat faced by C. vettonica populations due to low genetic diversity and genetic introgression with C. paludica.

Summary: In this study, we used satellite mapping tools to obtain environmental parameters, geometric morphometry to analyze body shape, and mitochondrial DNA analysis to identify species. Results showed that the change in body shape of Sabanejewia species is significantly influenced by locality elevation and specimen's sex. We also found significant differences in the number of lateral spots, which are considered mimicry variation across an elevation gradient. Morphological differences in Sabanejewia spp. vary with ecological factors along the river continuum.

Summary: The study conducted a comparative analysis of the morphological, genetic, and ecological features of Russian, Persian, and Colchic sturgeons to assess their taxonomic relations, confirming the presence of two closely related and morphologically similar species in the Caspian basin. The Colchic sturgeon remains virtually unstudied genetically and is considered to be an independent subspecies of the Persian sturgeon. Further research is needed to explore the distribution of the Colchic sturgeon in the Black Sea basin.
