Environmental change is continuing to affect the flow of nutrients, material and organisms across ecosystem boundaries. These cross-system flows are termed ecosystem subsidies. Here, we synthesize current knowledge of cross-ecosystem nutrient subsidies between remote lakes and their surrounding terrain, cryosphere, and atmosphere. Remote Arctic and alpine lakes are ideal systems to study the effects of cross ecosystem subsidies because (a) they are positioned in locations experiencing rapid environmental changes, (b) they are ecologically sensitive to even small subsidy changes, (c) they have easily defined ecosystem boundaries, and (d) a variety of standard methods exist that allow for quantification of lake subsidies and their impacts on ecological communities and ecosystem functions. We highlight similarities and differences between Arctic and alpine systems and identify current knowledge gaps to be addressed with future work. It is important to understand the dynamics of nutrient and material flows between lakes and their environments in order to improve our ability to predict ecosystem responses to continued environmental change.

北极和高山湖泊的跨生态系统养分补贴:全球变化对偏远湖泊的影响。

环境变化继续影响跨生态系统边界的养分,物质和生物的流动。这些跨系统流动被称为生态系统补贴。在这里,我们综合了偏远湖泊及其周围地形,冰冻圈和大气之间有关跨生态系统养分补贴的当前知识。偏远的北极和高山湖泊是研究跨生态系统补贴影响的理想系统,因为(a)它们位于经历快速环境变化的位置,(b)它们对很小的补贴变化都具有生态敏感性,(c)易于定义生态系统边界,以及(d)存在各种标准方法,可以量化湖泊补贴及其对生态群落和生态系统功能的影响。我们着重指出了北极和高山系统之间的异同,并指出了当前的知识差距,需要在未来的工作中加以解决。重要的是要了解湖泊及其环境之间养分和物质流动的动态,以提高我们预测生态系统对持续环境变化的反应的能力。
