Soils on the Tibetan Plateau are extremely sensitive to global climate change .The lack of understanding of soil organic matter ( SOM ) transformation processes in this region hinders the prediction of SOM stocks under future climate conditions .Recently , Prof . Gengxin Zhang ’ s group of Institute of Tibetan Plateau Research , Chinese Academy of Sciences studied the responses of the alpine SOM to global climate change , including Nitrogen ( N ) deposition , warming and increased precipitation .

The rare biosphere contains microorganisms that present in low abundance .These rare microorganisms represent the majority of the Earth ' s biodiversity and are responsible for ecosystem multifunctionality and act as the “ seed bank ” during ecological restoration .However , the diversity and biogeography of rare microorganisms are still poorly understood in the terrestrial ecosystem .Fig . 4 Correlations between the community composition and phylogeny for rare and abundant bacteria ？.

Although biodiversity and ecosystem functions are strongly shaped by contemporary environments , such as climate , local biotic and abiotic attributes , we know relatively little about how they change along with long-term geological processes .The integration of geological processes with environmental gradients could enhance our understanding of biodiversity and ecosystem functioning across different climatic zones . ？ ？ Further studies are encouraged to study the legacies of past geological events on biological communities and ecosystem functions .

Chinese Academy of Sciences has led a study to image the small-scale structure of the D ' ' layer beneath the India-Eurasian plate collision zone . ？ ？ This study is mainly based on the waveform data of eight earthquakes in the Indian Ocean recorded by the dense China Digital Seismic Network ( Figure 1b ) .The median value of δ t3D is - 1.75 s and 95% of the values fall between - 4.57 s and + 1.63 s . ( b ) Values of dVs plotted at the CMB reflection points of ScS . ( c ) Map of dVs after cap smoothing using caps with radii of 2o and cap centers spaced every 0.5o .

Many researches reported that warming alters soil freeze-thaw ( F-T ) process during winter in cold regions , such as the start and end dates , frequency and intensity .And how these changes will affect the annual ecosystem respiration . ？ They found that warming delayed the start and end dates of F-T events during the freezing period , and advanced them during the thawing period .Periods ？ ？ Figure3 Mean total ecosystem respiration ( Re ) during the thawed period and annually.

Land surface processes and summer cloud-precipitation characteristics in the Tibetan Plateau ( TP ) have significant impacts on downstream weather and climate changes .It was revealed that the eastward propagation of convective systems caused by TP heating had profound impacts on the downstream rainstorms over the Yangtze River Basin . The mechanisms were mainly attributed to the interactions among the TP heating .The third is how to get an accurate latent heat profile of cloud precipitation in the TP from the observed data in order to evaluate the latent heat structure of the model .

A technical comments paper focused on the paleoaltimetry simulation of Tibetan Plateau jointly authored by the Institute of Tibetan Plateau Research , Chinese Academy of Sciences ( ITPCAS ) .This paper concluded that an extensive Tibetan Plateau exceeding 4000 m above sea level ( a . s . l . ) existed in middle Eocene . It further commented the Science paper titled " Revised paleoaltimetry data show Tibetan Plateau elevation during the Eocene " by Botsyun and others . ？ The uplifting history of the Tibetan Plateau links together the.
