As environmental disturbance, fragmentation, and pollution become more widespread, it is imperative that new collaborative mutidisciplinary research provide insights into complex ecological phenomena on a larger scale than has been possible in the past. The facility that is the subject of this project is a regional center for research on the responses of lake systems to disturbance at varying scales. The investigators associated with this facility have many years of experience using small experimental surrogate ecosystems(e.g.. experimental ponds) to identify the responses to disturbance of larger, "real world", systems. The objective of this project is to enhance the aquatic research facility at the University of Kansas field station, the Kansas Ecological Reserves (KER), in order to continue the extension of this work to larger scales. The aquatic facilities at the KER are extensive with nearly 200 experimental ponds over 55 outdoor fiberglass tanks and different types of enclosures for smaller scale experiments within these systems. Research over the 20 year history of this aquatic program, reported in nearly 100 publications, has often focused on the use of these relatively small surrogate ecosystems for aquatic research. This work has firmly established that experimental perturbations applied to these surrogate adequately simulate a variety of environmental changes. New modeling techniques are being developed to extrapolate these results to the "real world at larger spatial and temporal scales. To extend this empirical research to larger lentic ecosystems )lakes and reservoirs). 1991 a 4.5 ha, 13 m deep reservoir was constructed in a protected 50 ha watershed. This reservoir was constructed as a model ecosystem with many of the important characteristics of larger lentic systems. Now investigators working at KER can conduct empirical investigations in a large, secure and carefully managed lake/ reservoir surrogate. The proximity of this lar ger scale surrogate ecosystem to one of the largest experimental pond facilities in the nation makes the facility attractive to researchers from institutions throughout the region. No limnological manpipulations are conducted in the reservoir at the whole-lake scale so that natural reference conditions can be continually provided. However, experimental perturbations simulating environmental change at this reservoir scale can be studied in situ enclosures and in adjacent smaller experimental ponds and tanks.

随着环境干扰、破碎化和污染变得越来越普遍，新的多学科合作研究必须在比过去更大的范围内提供对复杂生态现象的见解。 作为该项目主题的设施是一个区域中心，研究湖泊系统对不同尺度干扰的反应。 与该设施相关的研究人员具有多年使用小型实验替代生态系统的经验（例如，实验池塘）来识别对更大的“真实的世界”系统的干扰的响应。 该项目的目标是加强堪萨斯大学野外站的水生研究设施，即堪萨斯生态保护区，以便继续将这项工作扩大到更大的规模。 KER的水上设施非常广泛，有近200个实验池塘，55个室外玻璃纤维水箱和不同类型的围栏，用于这些系统内的小规模实验。 在近100份出版物中报道的这一水生项目20年历史的研究，往往集中在使用这些相对较小的替代生态系统进行水生研究。 这项工作已经牢固地建立了实验扰动施加到这些代理充分模拟各种环境变化。 正在开发新的建模技术，以将这些结果外推到更大空间和时间尺度上的“真实的世界”。 将这一经验研究扩展到更大的静水生态系统（湖泊和水库）。 1991年，在一个受保护的50公顷流域内建造了一个4.5公顷、13米深的水库。 这个水库是作为一个生态系统模型建造的，具有大型透镜体系统的许多重要特征。 现在，在KER工作的调查人员可以在一个大型、安全和精心管理的湖泊/水库替代物中进行实证调查。 这个格尔的替代生态系统接近全国最大的实验池塘设施之一，使该设施吸引了整个地区的研究机构。 水库不进行全湖尺度的湖沼学人工调控，可持续提供自然参照条件。 然而，在这个水库规模的模拟环境变化的实验扰动可以在原位外壳和相邻的较小的实验池塘和坦克进行研究。
