    “[The researchers] measured carbon emissions and water chemistry in 50 headwater rivers draining 780,000 km² of the Tibetan Plateau.
    The rivers flow in landscapes underlain by continuous permafrost and landscapes in which the permafrost has retreated since the last glacial maximum. They collect[ed] organic carbon from soils and dissolved inorganic carbon that is fixed by rock-weathering.
    Where the permafrost cover is continuous, rivers emit CO2 from degrading (permafrost) soil carbon. Weathering reactions in these catchments are relatively slow.
    In landscapes with (almost) no permafrost, carbon fluxes from weathering are faster than CO2 emissions from rivers.
    Thus, as permafrost landscapes transition to landscapes without permafrost cover, chemical weathering reactions may play an ever more important role in riverine carbon cycling.
    Interestingly, weathering can affect the carbon cycle in different ways. Where sulfide minerals are present, weathering reactions can emit CO2. Where silicate minerals dominate, weathering draws down CO2 from the atmosphere…”

    “Climate-induced permafrost thaw unlocks large stores of organic carbon that are mineralized and emitted as carbon dioxide (CO2) from rivers to the atmosphere. Concurrently, warming and permafrost thaw can increase mineral weathering rates, thus affecting the release and sequestration of inorganic carbon. Yet how these biological and geological carbon cycles interact and jointly affect CO2 dynamics (emission compared with drawdown) in permafrost rivers remains unknown. Here [they] combine[d] CO2 emissions, organic and inorganic solute concentrations, dual carbon isotopes (δ13C–Δ14C) and geochemical modelling to infer how permafrost thaw may affect river biogeochemistry over decades to centuries across the Qinghai–Tibet Plateau. Leveraging a gradient of thermal permafrost degradation, we find that river CO2 emissions decline, whereas solute fluxes from rock weathering increase with decreasing permafrost cover. Across this region, net CO2 drawdown fluxes from rock weathering are about 35% of river CO2 emissions, varying from around 15% in catchments with continuous permafrost to more than 100% in catchments with discontinuous or isolated permafrost. Thus, carbon fluxes from chemical weathering may become increasingly important with ongoing permafrost thaw, potentially even outpacing river CO2 emissions. [Their] findings disentangle the interplay between biological and geological carbon fluxes that are important for the cryosphere and the global carbon cycle…”

  4. Winds Above Tibet: A Quiet Resupply for Asia's Thirsty Billions

    New research shows winds help Asia's Water Towers supply water to nearly 2 billion people. Climate change is making this harder.

  6. #Nitrogen enrichment can have a negative impact on #CommunityResistance, but can accelerate the recovery process. This is mainly achieved by affecting the #AsynchronyOfSpecies rather than the resistance or resilience of plant diversity.

  7. 【Perspective】
    Human-accelerated Holocene vegetation change is greater than expected on the Tibetan Plateau.

    Peng-Chao Zhang et al. analyzed 61 records of filtered fossil pollen sequences from sediment cores across the #TibetanPlateau to assess changes in #FloristicDiversity.

  9. (3/4) 🌍 We found that most publications came from Central Europe (mainly the #EuropeanAlps) and Central Asia (#TibetanPlateau).

    The research focus on each global mountain region differed: a research hub on alpine soil fauna is found in Central Europe, for #biocrusts also in Northern Europe, and for microbiota in Central Asia.

    Most other mountain regions are still underrepresented, and more research should be conducted there to fill crucial knowledge gaps. 🏔️

  10. Shuping Guan et al. investigated the relative contributions of #PlantTraits to the potential #EcologicalImpacts of #InvasivePlantSpecies. But the results showed that there was no correlation between invasiveness and impacts of invasive species on the #TibetanPlateau.

  11. Le Sun et al. pointed that the trade-off pattern of #Biomass of #AlpineGrasslands is not only determined by plant community traits and functions on the #TibetanPlateau, but also regulated by #Precipitation regimes.

  12. Yang Lin et al. simulated the impacts of different #ForestManagementOptions on forest #AbovegroundCarbonSequestrationRate (ACSR) in the eastern #TibetanPlateau. The result showed that low intensity and longer intervals harvest and planting can significantly improve alpine forest ACSR.

  13. Ge Hou et al. found that the #DominantSpecies predominated #CommunityStability by promoting the community #DominantSpeciesStability (DSS) and #SpeciesAsynchrony in the #AlpineGrasslands on the northern #TibetanPlateau. Mean-while, community species dominance contributed to the DSS. Protecting locally dominant species can stabilize the ecosystem functions of alpine grasslands.

    ✧ yak ✧

    The yak (Bos grunniens) is a species of long-haired domesticated cattle in the family Bovidae. It is found throughout the Himalayas in Pakistan, India, the Tibetan Plateau of China, Tajikistan, and as far north as Mongolia and Siberia, Russia. Yak physiology is well adapted to high altitudes and cold weather, featuring larger lungs and heart than ...

  15. "By 2100, even under a low-emissions scenario, the surface area of endorheic #lakes on the #TibetanPlateau will increase by over 50 per cent (around 20,000 sq km [7,722 square miles]) and water levels will rise by around 10 metres [32 feet] relative to 2020. Endorheic lakes, also known as closed lakes, do not have an outlet to drain into.

    This has mostly been driven by increases in net precipitation."

  16. 📢#OutNow in #OA: '#Shépa: The #Tibetan #OralTradition in #Choné', by Bendi Tso, Marnyi Gyatso, Naljor Tsering & Mark Turin acting as Trustees for the Members of the Choné Tibetan Community.

    This book contains a unique collection of #Tibetan #oralnarrations and songs known as #Shépa, as these have been performed, recorded and shared between generations of #Choné Tibetans from #Amdo living in the eastern #tibetanplateau.

    Presented in trilingual format — in #Tibetan, #Chinese &English — the book reflects a sustained collaboration with and between members of the local community, including narrators, monks, and scholars, calling attention to the diversity inherent in all oral traditions, and the mutability of #Shépa in particular.

  17. The Tibetan plateau, known as the “roof of the world”, was not the last place to be settled by humans or hominins, as previously thought. Archaeological evidence shows that ancient humans adapted to the harsh conditions of this region, which is cold, dry, and has low oxygen levels, as early as 160,000 years ago. #TibetanPlateau #HumanEvolution #Archaeology newscientist.com/article/23865

  20. They found that when it gets warmer in the #Amazon, temperatures also rise in #Tibet. But when rain increases in the #SouthAmerican #rainforest, snowfall decreases in the #Himalayan region, sometimes called the " #ThirdPole ".

    Using snow cover data, the scientists also detected what they say are early warnings the #TibetanPlateau has been approaching a tipping point of its own since 2008.
