Summary: This study focuses on the impact of vegetation dynamic induced change on catchment water yield in Qinghai Lake Basin. By using ecohydrological models, water balance methods, and surface runoff experiments, it is found that plant drought adaptation strategies can significantly affect water yield. Plants employing drought-avoiding strategy have higher water yield, while plants adopting drought-tolerating strategy have higher productivity. These findings offer important insights into the biological mechanism of water yield regulation by vegetation and provide guidance for watershed management.

Summary: The study found that major transposons in the Glyptosternon maculatum genome exhibited episodic bursts, in accordance with geological and climatic events during the Qinghai-Tibet Plateau formation. Expansion of histone genes in the genome was significantly increased, likely mediated by long interspersed nuclear elements (LINE) repetitive element duplications. Population analysis revealed that ancestral Glyptosternon maculatum populations experienced two significant depressions 2.6 million years ago and 10,000 years ago, aligning with Quaternary glaciation and the Younger Dryas period.

Summary: The Qinghai-Tibet Plateau has exceptional species diversity, with various studies exploring the reasons for species formation in the region and the environmental adaptation of high-altitude species. Despite disputes, research has shown that the uplift of the plateau is heterogeneous and supported by abundant fossils for an asynchronous upheaval model. Genomic evidence has identified numerous candidate genes for high-altitude adaptation.

Summary: The study found that the alpine tetraploid Allium tetraploideum evolved from at least two closely related diploid species, with at least one extinct diploid species involved in its ancestry. It appears that A. tetraploideum arose via homoploid hybrid speciation from two extinct allotetraploid parents, which further derived from the aforementioned diploids, showcasing the complex origins of some polyploid species involving both homoploid hybrid speciation and extinct ancestors.

Summary: This study investigated the adsorption capacity of biochar from three typical vegetation types in the Qinghai-Tibet Plateau for Cd2+ in water. The results showed that biochar prepared at 650 degrees C had the highest adsorption capacity, with Chinese wolfberry showing the highest adsorption among the three types. The effects of biochar dosage, experimental temperature, and biochar preparation temperature on Cd2+ adsorption were also studied.

Summary: By using the MaxEnt model, this study identified the distribution patterns of 19 ungulate species on the Qinghai-Tibet Plateau and found that their habitats have been greatly affected by human activities and climate change. The majority of these species are mainly distributed in the southeast of the plateau, and the key protected areas identified by the Zonation model are mainly located in this region as well. This research provides a scientific basis for addressing the development-protection contradiction and promoting biodiversity conservation on the Qinghai-Tibet Plateau.

Summary: In this study, the tolerance of six Barbini fishes to environmental stress factors at different altitudes and regions was compared through stress experiments and histological experiments. Results showed that the tolerance of fishes to high-altitude environmental stress factors was closely related to the environmental stress of their main habitats. Among these factors, middle- and low-altitude fishes showed common low tolerance to UVR, suggesting that high UVR plays an important role. Moreover, the disappearance of Schizothorax fish during the uplift of the Qinghai-Tibet Plateau may be caused by its intolerance to the increasingly extreme plateau environment, especially salinity.

Summary: This study focuses on snowfinches as a monophyletic group of passerine birds to explore the evolution of species-specific adaptations in extreme high-elevation environments, especially the Qinghai-Tibet Plateau. The research reveals that about 95% of genes under positive selection in the descendant species differ from those in the ancestor, leading to differences in enriched biological functions among these species. The study also shows an exceptional case of adaptive evolution in high-elevation environments, indicating an initial adaptation in the common ancestor followed by adaptive diversification of the descendant species.

Summary: The study explores the origins of plant diversity in the Qinghai-Tibetan Plateau using Orchidinae as a model. The results show that the species-richness of Orchidinae in the QTP arose through in situ diversification, colonisation, and local recruitment. Adaptations in clades from North Temperate and alpine regions were crucial for this diversification, with multiple origins of species-richness identified. Most endemic species evolved within the past six million years.

Summary: Climate is an important factor in determining livability, and this study focuses on climate suitability in high-altitude areas. By adding oxygen content and solar radiation as indicators, the study develops the Climate Suitability Index of Plateau (CSIP) to assess climate suitability on the Qinghai-Tibet Plateau. The results show that the climate becomes increasingly unsuitable from southeast to northwest, and the plateau is divided into four regions based on the CSIP.

Summary: This study examines the genomic divergences between two sister plant species, Medicago ruthenica and M. archiducis-nicolai, that occur in northern China and the northeast Qinghai-Tibet Plateau, respectively, with overlapping distributions in the border of the two regions. The results show that the two species have diverged from each other in the Quaternary but have been in continuous contact with gene flow occurring between them. Positive selection signatures associated with genes involved in adaptations to arid and high-altitude environments are also discovered. These findings provide insights into the interspecific divergence of these two sister species.

Summary: Atomic replacement on platforms of nonfullerene acceptor (NFA) can optimize the performance and enhance energy levels, absorptions, and charge transfer dynamics. The newly developed NFA FOSe-2Cl, which replaces sulfur atoms with selenium atoms, shows improved energy levels, redshifted absorption, enhanced molecular packing, and accelerated charge transfer/transport dynamics compared to FO-2Cl. The organic solar cell based on FOSe-2Cl achieves a significantly improved power conversion efficiency (PCE) of 15.94% and reduced energy loss (E-loss) of 0.670 eV.

Summary: Optimizing the molecular packing and orientation of dopant-free hole-transport materials (HTMs) is an effective strategy for achieving high-performance perovskite solar cells (PSCs). By regulating the donor building blocks and using a large core unit, we successfully demonstrated tunable molecular packing and orientation of polymers. The developed PC-DPP conjugated polymer with a preferred face-on orientation showed enlarged hole mobility and improved efficiency in PSCs compared to the control PBDT-DPP polymer with a preferred edge-on orientation. This work opens up possibilities for developing dopant-free HTMs.

Summary: There is a significant efficiency gap between organic solar cells (OSCs) and inorganic solar cells. This is primarily due to the larger nonradiative energy losses in OSCs, which can be attributed to the characteristics of organic light-harvesting molecules. Rational design of light-harvesting molecules at the molecular and aggregation levels is crucial for improving the efficiency of OSCs.

Summary: Three non-fullerene acceptors BTP-OC4, BTP-OC6, and BTP-OC8 with different 4-alkyloxyphenyl side-chains were synthesized via a new route without organotin reagent. The length of the alkyloxy group did not affect the energy levels and absorption of the acceptors, but it modulated the crystallinity and morphology of the active layer. The PM6:BTP-OC6 system showed the lowest energy loss of 0.513 eV, the highest power conversion efficiency of 17.59%, and excellent stability. Furthermore, when Y6 was introduced, the PCE increased to over 18%. Our study demonstrates a feasible strategy to develop high-performance acceptors by fine-tuning the aromatic side chain.

Summary: This study systematically investigated the effects of different side-chain alkyl chain lengths on the performance and photovoltaic efficiency of non-fullerene acceptors. The results showed that increasing alkyl chain length improved the open-circuit voltage but had a parabolic trend on short-circuit current density, fill factor, and power conversion efficiencies. The proper alkyl side chain also optimized the molecular packing and carrier mobility, enhancing the overall photovoltaic performance.
