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.

为了理解和预测对环境变化的复杂生态反应，例如在大陆和全球尺度上发生的氮沉积以及物种入侵和灭绝，迫切需要大规模实验。营养网络或NUTNET是一个合作网络，由60多个科学家组成，在北美，欧洲，澳大利亚，南美，亚洲和非洲的40多个地点。 作为一个小组，Nutnet成员正在世界上的草原上进行相同的实验，以带来独特的高质量数据，以解决这些重要的生态问题。 网络参与者已同意提供自己的资金，以支持NutNet实验地块的安装，维护和采样。 因为全球研究人员参与NUTNET已经大大超过了最初的期望，因此目前的赠款将资助与核心网络参与者一起设计和实施基于Web的数据和元数据输入表格，确保网络范围的数据质量，生产教育和外展产品，并计划和执行几个网络会议。磷径流，空中氮沉积）和消费者（例如引入物种）控制植物群落和世界各地草原的生态系统服务。尽管已经在我们网络中的许多单个站点进行了针对该目标的部分的研究，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，该环境促进了全球研究合作，这将提高我们在面对全球巨大变化时预测生态系统响应的能力。 此外，NutNet还以共同的研究目标培养了全球包容性研究人员的研究社区。 由于与设置和采样单个Nutnet网站相关的费用很小，因此许多当前的Nutnet合作者是年轻的研究人员或来自发展中国家的研究人员。 所有NutNet参与者的综合努力将产生前所未有的范围的复制实验基础设施。 Nutnet应该出现一些引人注目的出版物，以解决紧迫的社会问题，例如草地对富营养化的反应。
