美国国家科学基金会资助的长期生态研究（LTER）网络支持大量（约240个）和多样化的长期生态实验组合。总的来说，这些长期实验（a）提供了对生态模式和过程的独特见解，尽管这种见解往往要经过多年研究才变得明显;（B）影响了管理和政策决定;（c）演变成支持研究并让最初设计中没有参与的调查人员参与的研究平台。此外，这套长期的实验地址，在现场一级，所有的美国国家研究理事会的环境科学的大挑战。尽管有这些贡献，我们认为，全球环境变化的规模和范围需要一个更协调的多站点的方法来进行长期实验，理想情况下，这种方法将包括一个网络的空间广泛的多因素实验，设计与生态建模，将建立和扩展的独特环境提供的LTER网络。
The US National Science Foundation funded Long Term Ecological Research (LTER) Network supports a large (around 240) and diverse portfolio of long-term ecological experiments. Collectively, these long-term experiments have (a) provided unique insights into ecological patterns and processes, although such insight often became apparent only after many years of study; (b) influenced management and policy decisions; and (c) evolved into research platforms supporting studies and involving investigators who were not part of the original design. Furthermore, this suite of long-term experiments addresses, at the site level, all of the US National Research Council's Grand Challenges in Environmental Sciences. Despite these contributions, we argue that the scale and scope of global environmental change requires a more-coordinated multisite approach to long-term experiments, ideally, such an approach would include a network of spatially extensive multifactor experiments, designed in collaboration with ecological modelers that would build on and extend the unique context provided by the LTER Network.
