项目摘要

The International Tundra Experiment (ITEX) was chartered in 1990 to test the effects of increased temperature on tundra plant phenology, growth, species composition and ecosystem function. Since 2007, the ITEX-Arctic Observatory Network (ITEX-AON) has continued and expanded on the ITEX program across a latitudinal transect of five sites in Alaska and Greenland, collecting core ITEX data specifically designed to address the current needs outlined in the Study of Environmental Arctic Change (SEARCH) Implementation Report. The goal of this effort is to maintain the continuity of the temporally-critical datasets of the ITEX-AON in Alaska and Greenland. Core datasets include the long-term manual observations of phenology, vegetation structure and composition, ecosystem function, and surface properties on the long-term ITEX control and experimental warming plots, repeat measurement of the vegetation plots on the 1km2 ARCSS grids, and a multifactor warming-moisture experiment in Greenland. The simultaneous measurement of multiple surface properties at the small scale has allowed detection of relationships not previously recognized, e.g., in moss-dominated areas of the intensive transects, higher albedo is linked to higher temperatures. Continuation of these measurements is imperative because increasing evidence points towards the critical importance of carry-over effects of the previous growing seasons on current and future responses and the inherent variability in the system precluded determination of the system response on the basis of a few years. Data from this project are freely available on the ACADIS website. The project will continue extensive outreach activities established in the initial phase, including strong relationships between the Fairchild Tropical Botanic Garden (FTBG) and the GVSU Regional Math and Science Center and school systems in Miami, Anchorage, Grand Rapids, and El Paso.
1990年特许进行了国际冻原实验,以测试温度升高对冻原植物物候、生长、物种组成和生态系统功能的影响。 自2007年以来,ITEX-北极观测网(ITEX AON)在阿拉斯加和格陵兰的五个地点的纬度样带上继续并扩大了ITEX方案,收集专门为满足《北极环境变化研究执行报告》中概述的当前需求而设计的ITEX核心数据。 这项工作的目标是保持阿拉斯加和格陵兰ITEX-AON的时间关键数据集的连续性。 核心数据集包括长期人工观测的物候,植被结构和组成,生态系统功能,和表面特性的长期ITEX控制和实验变暖的地块,重复测量的植被地块上的1平方公里的ARCSS网格,并在格陵兰岛的多因素变暖-水分实验。 在小尺度上同时测量多个表面性质允许检测先前未认识到的关系,例如,在密集样带的苔藓为主的地区,较高的温度与较高的温度有关。 这些测量的继续是必要的,因为越来越多的证据指向的关键重要性的结转影响以前的生长季节对当前和未来的反应和固有的可变性,在系统中排除了确定的系统响应的基础上,几年。 该项目的数据可在ACADIS网站上免费获得。 该项目将继续在初始阶段建立广泛的外联活动,包括费尔柴尔德热带植物园(FTBG)和GVSU地区数学和科学中心以及迈阿密、安克雷奇、大急流城和埃尔帕索的学校系统之间的密切关系。
