We request support to acquire equipment needed to enhance our program of environmental research, which emphasizes interactions of organisms and ecosystem function. The equipment will significantly upgrade and expand two interactive facilities used by the six PIs in our separate and collaborative research: an environmental analytical chemistry laboratory (the CERE EAL) and a controlled environment facility (the CERE CEF). The capabilities of these two facilities are intimately linked; the laboratory components of most of our field-based studies require controlled environment chambers, and both the field and laboratory aspects require determinations of various nutrients and ions. Our group includes plant, animal, and microbial ecologists with expertise in aquatic and terrestrial ecosystems, whose work ranges from the level of organismal behavior and physiology to community and ecosystem dynamics. Our group is highly collaborative, and our individual and collaborative research is relevant to many issues of conservation and management importance in the Intermountain West. We provide significant research training opportunities at the undergraduate, graduate, and postdoctoral levels. Collectively, we are the major advisors for 44 graduate students, 5 postdoctoral research associates, and numerous undergraduate research assistants or independent study students. We will replace obsolete equipment and add new pieces of state-of-the-art equipment with improved capabilities over those we currently have. We request two major pieces of equipment that will greatly improve the sample processing capacity and data quality obtainable from our analytical laboratory, an Alpkem FLOWSolution autoanalyzer (model 3590, base system A001280) and a Carlo Erba NA1500 CHNS combustion analyzer. These models are necessary to increase the sample number we can process and, also importantly, to improve our abilities to accurately determine low concentrations of nutrients and ions, especial ly nitrate, ammonium, and total nitrogen. We also request two walk-in, four reach-in, and four small benchtop environmental chambers to replace obsolete equipment and add additional controlled environment space. These chambers will equip a controlled environment facility that Idaho State University will build as part of a new greenhouse complex, with construction scheduled to be completed in January 1995. Although we understand that building cannot contribute to the match for this proposal, this greenhouse complex has a building cost of greater than $300,000 and is being built largely to support the research and research training of our group. The controlled environment room was added to the building plans in direct support of this proposal, at an estimated additional floor-space cost of $19,200. If this proposal is funded, we will be able to conduct our research more effectively, to undertake more collaborative research and more sophisticated research, to collect better quality data in a shorter time, and to expand our research programs. This will provide increased number and quality of research training opportunities to postdoctoral associates, graduate students and undergraduate students.

我们请求支持以获得加强我们的环境研究计划所需的设备，该计划强调生物体和生态系统功能的相互作用。该设备将显着升级和扩展六个 PI 在我们单独和协作研究中使用的两个交互式设施：环境分析化学实验室 (CERE EAL) 和受控环境设施 (CERE CEF)。这两个设施的功能密切相关；我们大多数实地研究的实验室部分都需要受控环境室，并且现场和实验室方面都需要测定各种营养素和离子。 我们的团队包括在水生和陆地生态系统方面具有专业知识的植物、动物和微生物生态学家，他们的工作范围从有机体行为和生理学水平到群落和生态系统动态。我们的团队高度协作，我们的个人和协作研究与西部山间保护和管理的许多重要问题相关。我们为本科生、研究生和博士后级别提供重要的研究培训机会。总的来说，我们是 44 名研究生、5 名博士后研究员以及众多本科生研究助理或独立学习学生的主要顾问。 我们将更换过时的设备，并添加新的最先进的设备，其功能比我们目前拥有的设备有所改进。我们需要两台主要设备，一台 Alpkem FLOWSolution 自动分析仪（型号 3590，基本系统 A001280）和一台 Carlo Erba NA1500 CHNS 燃烧分析仪，这将大大提高我们分析实验室的样品处理能力和数据质量。这些模型对于增加我们可以处理的样品数量是必要的，而且更重要的是，对于提高我们准确测定低浓度营养物和离子（特别是硝酸盐、铵和总氮）的能力来说是必要的。 我们还要求两个步入式环境室、四个步入式环境室和四个小型台式环境室来更换过时的设备并增加额外的受控环境空间。 这些室将配备爱达荷州立大学将建造的受控环境设施，作为新温室综合体的一部分，施工计划于 1995 年 1 月完工。尽管我们知道建筑无法为该提案的匹配作出贡献，但该温室综合体的建筑成本超过 300,000 美元，其建造主要是为了支持我们小组的研究和研究培训。受控环境室被添加到建筑计划中以直接支持该提案，预计额外占地面积成本为 19,200 美元。 如果该提案获得资助，我们将能够更有效地进行研究，进行更多的合作研究和更复杂的研究，在更短的时间内收集更高质量的数据，并扩大我们的研究项目。这将为博士后、研究生和本科生提供更多数量和质量的研究培训机会。
