In this article marking the 40th anniversary of the US National Science Foundation's Long Term Ecological Research (LTER) Network, we describe how a long-term ecological research perspective facilitates insights into an ecosystem's response to climate change. At all 28 LTER sites, from the Arctic to Antarctica, air temperature and moisture variability have increased since 1930, with increased disturbance frequency and severity and unprecedented disturbance types. LTER research documents the responses to these changes, including altered primary production, enhanced cycling of organic and inorganic matter, and changes in populations and communities. Although some responses are shared among diverse ecosystems, most are unique, involving region-specific drivers of change, interactions among multiple climate change drivers, and interactions with other human activities. Ecosystem responses to climate change are just beginning to emerge, and as climate change accelerates, long-term ecological research is crucial to understand, mitigate, and adapt to ecosystem responses to climate change.
在这篇纪念美国国家科学基金会长期生态研究（LTER）网络成立40周年的文章中，我们阐述了长期生态研究视角如何有助于深入了解生态系统对气候变化的响应。自1930年以来，在从北极到南极的所有28个LTER站点，气温和湿度变率都有所增加，干扰频率和强度增大，且出现了前所未有的干扰类型。LTER研究记录了对这些变化的响应，包括初级生产力改变、有机和无机物质循环增强以及种群和群落的变化。尽管一些响应在不同生态系统中具有共性，但大多数是独特的，涉及特定区域的变化驱动因素、多种气候变化驱动因素之间的相互作用以及与其他人类活动的相互作用。生态系统对气候变化的响应才刚刚显现，随着气候变化加速，长期生态研究对于理解、减轻和适应生态系统对气候变化的响应至关重要。
