项目摘要

The Niwot Ridge/Green Lakes Valley (NWT) Long Term Ecological Research (LTER) is an interdisciplinary research program with the long-term goals of better understanding ecosystems within high mountain ranges and contributing to a general advance of knowledge in ecology. While twenty percent of the world population lives in river basins fed by melt waters from snow or glaciers, we know very little about how changes in snowpack and temperature in high mountain areas will affect biodiversity conservation or the management of water resources. Ecosystem responses to increasing temperature occur over many years to many decades, so long-term observations and long-term experiments are required to detect and understand those responses. The NWT LTER research provides an important reference point for regional, national, and global networks to measure changes in the water cycle and life at high elevations. The mountainous lands associated with NWT provides a natural laboratory in which to explore why some habitats may be very sensitive to changes in the environment while other areas may not be sensitive. The natural setting of NWT also provides many features that can help promote and develop an interest in science and nature, and inspire schoolchildren and the public to learn about the ecology of mountains and the tundra.The NWT LTER program builds on over 35 years of long-term measurements and experiments to better understand where and when climate change results in ecological change, and to elucidate the mechanisms that lead to responsiveness or stability in ecological systems. Specific objectives include (a) using long-term observations to characterize how high-mountain environments are responding to climate, (b) using long-term experiments to test hypotheses about the underlying drivers and integration among these responses, and (c) integrating this information in modeling frameworks to both refine understanding and forecast responses to future change. The research is conceptually organized around how climate change translates to ecological response across a spatially complex landscape and across ecological levels of organization. Proposed questions derive from theory on climate exposure in complex terrain and compensatory dynamics, and the long-term observations and interdisciplinary expertise at NWT allow comprehensive tests of these theories. Specific investigations are framed by substantial variation in ecological responses to long-term trends in climate at NWT involving warmer spring and summer temperatures, earlier snowmelt and lake ice-off, and longer growing seasons. Research will focus on treeline and subalpine forest, and alpine and subalpine lakes, and alpine tundra ecosystems. Outreach and training addresses a broad range of audiences, including K-12 students, the general public, and citizen scientists, while emphasizing training of graduate students in science communication and engaged scholarship.
Niwot Ridge/Green Lakes Valley (NWT)长期生态学研究(LTER)是一个跨学科的研究项目,其长期目标是更好地了解高山脉的生态系统,并为生态学知识的普遍进步做出贡献。虽然世界上20%的人口生活在由积雪或冰川融水提供水源的河流流域,但我们对高山地区积雪和温度的变化将如何影响生物多样性保护或水资源管理知之甚少。生态系统对温度升高的反应持续多年到几十年,因此需要长期观察和长期实验来探测和了解这些反应。NWT LTER研究为区域、国家和全球网络测量高海拔地区水循环和生命变化提供了重要的参考点。与西北西北地区相关的山区提供了一个天然实验室,可以探索为什么有些栖息地对环境变化非常敏感,而其他地区可能不敏感。西北地区的自然环境也提供了许多特色,有助于促进和培养对科学和自然的兴趣,并激励学童和公众了解山区和苔原的生态。NWT LTER项目建立在超过35年的长期测量和实验的基础上,以更好地了解气候变化在何时何地导致生态变化,并阐明导致生态系统响应性或稳定性的机制。具体目标包括:(a)利用长期观测来描述高山环境对气候的响应;(b)利用长期实验来检验关于潜在驱动因素和这些响应之间整合的假设;(c)将这些信息整合到建模框架中,以完善对未来变化的理解和预测响应。该研究在概念上围绕气候变化如何转化为跨空间复杂景观和跨生态组织水平的生态响应进行组织。提出的问题源于复杂地形和补偿动力学的气候暴露理论,而西北西北地区的长期观测和跨学科专业知识可以对这些理论进行全面检验。具体的调查是根据西北西北地区对气候长期趋势的生态响应的实质性变化进行的,包括春季和夏季气温变暖、融雪和湖泊结冰提前以及生长季节变长。研究将集中在林木线和亚高山森林、高山和亚高山湖泊以及高山冻土带生态系统。外展和培训面向广泛的受众,包括K-12学生、普通公众和公民科学家,同时强调对研究生的科学传播和参与奖学金的培训。
