  摘要：Boreal forests provide considerable global land carbon storage and uptake, but they are being rapidly transformed to managed secondary forests, with poorly quantified implications for ecosystem carbon storage. Here we present data from extensive mapping and field inventories of carbon storage in primary forests in Sweden and use multiple methods to show that primary forests store similar to 72% (70 to 74% across methods) more carbon than managed secondary forests in vegetation, deadwood, soils...

  摘要：Our understanding of the timing of the human colonization of South America has been anchored by the Monte Verde II site in Chile, reported to date to similar to 14,500 years before the present (B.P.) and regarded as one of the most secure pre-Clovis archeological sites. We report the first independent investigation of Monte Verde in the nearly 50 years since initial excavations. We argue that radiocarbon and luminescence dates from alluvial exposures, in combination with the identification of ...
• Global cases of groundwater recovery after interventions AI翻译
  作者：Jasechko, Scott

  摘要：Groundwater depletion poses a challenge to irrigated agriculture and water access. Depleted aquifers can be refilled, but the interventions that have successfully refilled depleted aquifers are rarely reviewed. This work reviews 67 cases of groundwater recovery, where groundwater levels rose after a prolonged period of decline. The interventions that spurred groundwater recovery included policy changes, artificial groundwater recharge, and increased reliance on another water source instead of ...
