• New progress on Tibetan permafrost carbon inventory by Prof. YANG Yuanhe’s group of the IBCAS

  Permafrost is ice-containing soil, rock or sediment that is frozen for more than two consecutive years. Most permafrost is distributed in cold regions (high latitudes or high altitudes) across the Northern Hemisphere. During the last few decades, permafrost regions have experienced significant climate warming with widespread occurrence of permafrost thawing such as active layer deepening and thermal erosion. These thawing processes could result in the release of frozen carbon stock into the atmosphere, triggering positive carbon-climate feedback. Reliable evaluation of the permafrost carbon stock is the scientific basis for better understanding the direction and strength of the permafrost carbon-climate feedback. However, due to the lack of systematic field observations and appropriate upscaling methodologies, substantial uncertainties exist in the permafrost carbon budget, which limits our understanding on the fate of frozen carbon in a warming world.

  Why Flowers Look so Different: Scientists Make Progress in the Flexibility of Floral Structure and Its Underlying Mechanisms

  Arrangement of floral organs can be whorled or spiral. In whorled flowers, the numbers of floral organs are usually fixed; in spiral flowers, in contrast, the numbers of floral organs usually show considerable variation, suggestive of the flexibility in the basic structure of the flower. The underlying mechanisms of the flexibility, however, remain unclear. Using Nigella damascena (Ranunculaceae) as a model, Prof. KONG Hongzhi’s research group at Institute of Botany, Chinese Academy of Sciences, attempted to address this question.
