9416808 Bledsoe This project focuses on synthesis of below-ground productivity by plant roots at a number of sites in North America (LTER sites and other sites with significant root biomass information). Below-ground productivity is a key part of net primary productivity (NPP), yet there have been few efforts to compare below-ground productivity across different sites and develop synthetic hypotheses which might explain factors which control root growth and death and allocation of carbon to roots. This information is vital in understanding NPP, as well as in predicting effects of global change on NPP. The below-ground ecosystem has been neglected, essentially. The project has a dual objective: first, to develop a computer system which is suitable for intersite/synthetic research in root ecology; and second, to actually use that system for new scientific research. Specifically, the following below-ground productivity questions will be addressed: 1. How do abiotic variables (primarily climate and soil) affect below-ground root biomass in different ecosystems? 2. How does above-ground vegetation type affect below-ground root biomass in different ecosystems? 3. What relationships exist between above- and below-ground biomass parameters (density, health, resilience, etc.) in different ecosystems? The project is organized around a series of workshops in which ecologists (primarily root scientists) collaborate with information engineers (computer systems professionals with expertise in data-bases, application software, and networking). One pilot and two production workshops are planned. For each workshop the activities are similar: (1) design and prototyping of a root data-base and an associated application software-suite relevant to the ecosystem of interest: (2) validation of the prototype data-base and application software in a pre-workshop (limited to the organizers), followed by refinements to the system, as necessary; (3) collection of real-world data and metadata sets for topic ecosystem, and loading these data into the data-base with appropriate quality controls; (4) hosting of a formal workshop at which participants are challenged to make use the collected data-base and application software-suite, actually accomplishing intersite/synthetic science. The significance of the project is the information technology assistance it offers scientists in understanding how root ecology varies spatially and temporally across sites, and how it is affected by climate, soils, above-ground vegetation and other site-specific factors. Further, the project will evolve a series of data-bases and associated application software suites for intersite/synthetic work in ecology, to be published across the Internet, which hopefully will stimulate interest for similar efforts in other ecological disciplines.

9416808布莱索 该项目的重点是综合北美一些地点（长距离接触试验地点和其他具有重要根系生物量信息的地点）植物根系的地下生产力。 地下生产力是净初级生产力的重要组成部分，但很少有人努力比较不同地点的地下生产力，并提出综合假设来解释控制根系生长和死亡以及碳向根系分配的因素。 这些信息对于理解NPP以及预测全球变化对NPP的影响至关重要。 地下生态系统基本上被忽视了。 该项目有两个目标：第一，开发一个计算机系统，适用于根系生态学的跨地点/综合研究;第二，实际使用该系统进行新的科学研究。 具体而言，将处理以下地下生产力问题： 1.非生物变量（主要是气候和土壤）如何影响不同生态系统中的地下根系生物量？ 2.不同生态系统中地上植被类型如何影响地下根系生物量？ 3.地上和地下生物量参数（密度、健康、复原力等）之间存在何种关系在不同的生态系统中？ 该项目是围绕一系列研讨会，其中生态学家（主要是根 科学家）与信息工程师（计算机系统专业人员， 数据库、应用软件和网络方面的专业知识）。 一个飞行员和两个 生产车间正在规划中。 每个讲习班的活动类似：（1） 设计根数据库和与感兴趣的生态系统相关的相关应用软件套件并制作原型：（2）验证原型数据库， 应用软件在一个前讲习班（限于组织者），其次是 必要时对系统进行改进;（3）收集真实世界的数据和元数据 为主题生态系统建立数据集，并将这些数据以适当的质量加载到数据库中 （4）举办一个正式的研讨会，要求与会者 利用收集到的数据库和应用软件包， Intersite/合成科学。 该项目的意义在于它为科学家提供了信息技术援助 在理解根生态如何在空间和时间上变化，以及它如何 受气候、土壤、地上植被和其他特定地点因素的影响。 此外，该项目将发展一系列数据库和相关的应用软件 生态学中的站点间/综合工作套件，将在互联网上发布， 希望能激发人们对其他生态学科类似努力的兴趣。
