In order to understand and predict the complex ecological responses to environmental changes such as nitrogen deposition and species invasions and extinctions that are occurring at continental and global scales, there is an urgent need for large-scale experiments. The Nutrient Network, or NutNet is a collaborative network of over 60 scientists at more than 40 sites across North America, Europe, Australia, South America, Asia, and Africa. As a group, NutNet members are performing identical experiments in the world's grasslands to bring unique, high-quality data to bear on these important ecological issues. Network participants have agreed to provide their own funds to support the installation, maintenance, and sampling of NutNet experimental plots. Because participation in the NutNet by researchers around the globe has already vastly exceeded the original expectations, the current grant will fund a coordinator to work with the core network participants to design and implement web-based data and metadata entry forms, ensure network-wide data quality, produce education and outreach products, and plan and execute several network meetings.The NutNet is a uniquely global effort to gain a general understanding of the extent to which fertilization (e.g. nitrogen or phosphorus runoff, aerial nitrogen deposition) and consumers (e.g. introduced species) control plant communities and ecosystem services in grasslands around the world. While studies addressing parts of this goal have been conducted at many of the individual sites in our network, highly coordinated cross-site studies, such as the NutNet, are lacking. The NutNet also provides an innovative networking environment that promotes global research collaborations which will advance our ability to predict ecosystem responses in the face of enormous global changes. In addition, the NutNet also serves to foster an inclusive research community of investigators around the world with a common research goal. Because of the minimal expense associated with setting up and sampling a single NutNet site, many current NutNet collaborators are young investigators or those from developing countries. The combined efforts of all NutNet participants will produce a replicated experimental infrastructure of unprecedented scope. Several high-profile publications should arise from the NutNet, addressing pressing societal issues such as grassland responses to eutrophication.

为了了解和预测大陆和全球范围内发生的氮沉降和物种入侵和灭绝等环境变化的复杂生态反应，迫切需要进行大规模实验。 Nutrient Network（或 NutNet）是一个由遍布北美、欧洲、澳大利亚、南美、亚洲和非洲 40 多个地点的 60 多名科学家组成的协作网络。 作为一个团队，NutNet 成员正在世界各地的草原上进行相同的实验，以带来独特的高质量数据来解决这些重要的生态问题。 网络参与者同意提供自己的资金来支持 NutNet 实验地的安装、维护和采样。 由于全球研究人员对 NutNet 的参与程度已经远远超出了最初的预期，目前的赠款将资助一名协调员与核心网络参与者合作，设计和实施基于网络的数据和元数据输入表格，确保全网络数据质量，制作教育和推广产品，并计划和执行多次网络会议。 NutNet 是一项独特的全球性努力，旨在总体了解施肥（例如氮或氮）的程度 磷径流、空中氮沉降）和消费者（例如引进物种）控制着世界各地草原的植物群落和生态系统服务。虽然我们网络中的许多单独站点都针对这一目标进行了部分研究，但缺乏高度协调的跨站点研究，例如 NutNet。 NutNet 还提供了一个创新的网络环境，促进全球研究合作，这将提高我们在面临巨大的全球变化时预测生态系统反应的能力。 此外，NutNet 还致力于培育一个由世界各地具有共同研究目标的研究人员组成的包容性研究社区。 由于建立和采样单个 NutNet 站点所需的费用极低，许多当前的 NutNet 合作者都是年轻的研究人员或来自发展中国家的研究人员。 所有 NutNet 参与者的共同努力将产生一个规模空前的复制实验基础设施。 NutNet 应该会产生一些备受瞩目的出版物，解决紧迫的社会问题，例如草原对富营养化的反应。
