Summary: Genomic analysis revealed convergent evolution in Tibetan fishes adapted to high-altitude environments, with positively selected genes related to energy metabolism and hypoxia response. Functional assays demonstrated that von Hippel-Lindau (VHL) tumor suppressor genes in Tibetan fishes enhance hypoxia-inducible factor (HIF) activity under low-oxygen conditions. This study provides evidence of convergent genetic mechanisms for high-altitude adaptation in fishes on the Tibetan Plateau.

Summary: Quantifying the rhythms and rates of magmatic-hydrothermal systems is crucial for understanding the controls on ore formation and the dynamics of magmatic reservoirs. This study reconstructs the evolution of ore-forming fluids using hydrothermal quartz from a skarn in Tibet. The research reveals the existence of multiple pulses of magmatic fluids and a meteoric water incursion event, with estimated timescales in the millennium range. The study also suggests that magmatic reservoirs are mostly water unsaturated, with transient and episodic fluid exsolutions being driven by magma replenishment or crystallization-induced water saturation. Paleoelevation is quantified using δO-18 values from the quartz, indicating a transient early Miocene surface uplift likely caused by the break-off of an oceanic slab attached to the Indian Plate. This research demonstrates the importance of hydrothermal quartz in understanding magmatic-hydrothermal systems and quantifying paleoelevations, with significant tectonic implications.

Summary: The study reveals that endemic species started to colonize the TP as early as 55 million years ago, with the main colonization phase increasing around 15 million years ago and peaking after 6 million years. The major source areas for endemic TP species include the Hengduan Mountains, the Himalayas, and Central Asia. Elevation difference has the strongest effect on the source areas, followed by geographical distance. Significant differences were found among vertebrate classes in terms of spatio-temporal origins and potential drivers of endemic TP species.

Summary: This study investigates the impact of Tibetan Plateau vortex (TPV) on extreme precipitation events (EPEs) using TPV and precipitation datasets. The results show that TPV has a significant positive contribution to EPEs. EPEs tend to occur near the center and the southeastern quadrant of TPV. The structure and circulation of TPVs associated with EPEs are significantly different from those without EPEs.

Summary: The study analyzed the characteristics of rumen microbiota and metabolome, transcriptome, and serum metabolome of Tibetan sheep at different altitudes. The results showed close correlations between these characteristics and various biological pathways such as amino acid metabolism, lipid metabolism, and carbohydrate metabolism. There were also significant associations with the microbiota. Furthermore, the study identified common metabolites related to Tibetan sheep adaptation to plateau environmental changes that were significantly correlated with host genes.

Summary: This review discusses the temporal and spatial distribution of surface uplift in the Tibetan Plateau and the geodynamic mechanisms behind it. The initial collision between India and Asia and the subsequent formation of the high Tibetan Plateau are still not well understood, but the uplift is primarily controlled by delamination and break-off of the subducted Indian and Asian lithosphere.

Summary: Research on the genetic basis of hypoxic adaptation in high-altitude environments is active in evolutionary biology. The study investigated Hb concentration in fish at different altitudes, finding species-specific Hb concentration with a non-positive correlation with altitude. The discovery of positively selected Hb genes in schizothoracinae fishes indicates potential functional divergence in Hb isoforms.

Summary: Recent genomic analyses reveal that ancient gene flow could promote rapid diversification and adaptive radiation. Triplophysa, a loach genus mainly distributed in the Tibetan Plateau, demonstrates ecological diversity, rapid evolution, and potential adaptive radiation associated with the plateau's uplift. Through genome sequence analysis, phylogenetic reconstruction, introgression quantification, and simulation of speciation and migration processes, we find extensive gene flow events among different Triplophysa species. Our results indicate that introgression plays a more significant role than incomplete lineage sorting in supporting phylogenetic discordance in Triplophysa. Genomic regions affected by ancient gene flow exhibit lower recombination rates and nucleotide diversity, potentially linked to selection. Simulation analysis suggests that Triplophysa tibetana may have been affected by the Gonghe Movement during the third uplift of the Tibetan Plateau, leading to founder effects and a reduction in population size.

Summary: Unraveling the drivers that shape landscape genetics can provide a scientific basis for wildlife conservation and habitat management. In this study, the spatial genetic structure and determining factors of Schizopygopsis younghusbandi, a coldwater fish on the Tibetan Plateau, were explored using mitochondrial cytochrome b gene. The results showed high genetic diversity in higher, colder, and drier areas, and genetic differentiation among geographical populations. The Isolation-by-Environment model explained the genetic structure, with elevation and bioclimatic factors influencing population differentiation. Separate conservation units should be established, with special attention given to marginal populations with lower genetic variation.

Summary: The Tibetan Plateau vortices are the major precipitation-producing weather systems on the plateau, with a more significant impact in the warm season but also important in certain regions during the cold season. The interannual variation of vortices and associated precipitation is mainly determined by the number of vortices, while the heating anomaly caused by the Tibetan Plateau thermodynamic effect is also a significant factor.

Summary: During the extreme warming period, surface temperatures in glacial regions of the Tibetan Plateau have increased faster than non-glacial areas, and the duration and intensity of glacier surface heatwaves have significantly increased. These changes may pose potential threats to the sustainability of glacier water resources and increase the risk of glacier related hazards.

Summary: In 30 shallow lakes, patterns of functional and phylogenetic alpha diversity in fishes were examined, revealing no clear patterns among multiple biodiversity components and their environmental drivers, with no single component serving as a reliable proxy for another. Results suggest that accounting for both functional and phylogenetic diversity can help explain fish community variation.

Summary: Mercury biomagnification in aquatic ecosystems, especially in alpine regions like the Qinghai-Tibetan Plateau, is poorly understood. This study investigates the biomagnification potential of mercury in the food web of the Q-T Plateau and finds that the mercury concentrations exceed consumption guidelines in 26.75% of fish samples. The biomagnification rates on the Q-T Plateau are generally higher than global averages and are positively correlated with sediment mercury, elevation, and population density.
