A grant has been awarded to Drs. John V.H. Constable, Jerry G. Chmielewski, and Dean M. DeNicola at Slippery Rock University to purchase four controlled environment plant growth chambers. The requested chambers include control over temperature and illumination and will be configured as described below to maximize utility for all users. The configuration of the first pair of chambers includes a high light output option that provides illumination to approximately three-fourths of full sun level, control over humidity through linked humidification and dehumidification systems, and the control of CO2 concentration using CO2 injection and an integrated infrared gas analyzer. The configuration of the second pair of chambers are identical to those above, but lack the high light output option and control over CO2. Acquisition of these chambers will expand the future research efforts of John V.H. Constable; Jerry G. Chmielewski; and Dean M. DeNicola in the Department of Biology. The growth chambers will also expand Slippery Rock University's primary mission of excellence in undergraduate education in the classroom, the laboratory and independent faculty-supervised student research. The chambers will provide the capability for a diverse array of projects to be studied according to the primary research interests of the investigators. The goals of all proposed studies are to enhance our understanding of mechanistic relationships in biological systems. Dr. Constable's studies address the mechanistic relationship between nitrate and carbon assimilation at elevated CO2 that will enhance our predictive ability on the long-term growth response of vegetation to elevated CO2. Dr. Chmielewski's studies develop the understanding of evolutionary trends in reproduction between weedy and non-weedy aster species. Dr. DeNicola's investigations seek to build a predictive model of benthic algal succession based on growth form and potential colonizing taxa; and (ii) the determination of the effects of Acid Mine Drainage (AMD) on benthic algal community structure and primary production in order to improve remediation efforts in AMD impacted streams.

已向约翰·V·H博士提供赠款。警官，杰瑞·G Chmielewski和Dean M.迪尼古拉在滑岩大学购买四个受控环境植物生长室。 所要求的腔室包括对温度和照明的控制，并将按照下文所述进行配置，以最大限度地提高所有用户的效用。 第一对腔室的配置包括高光输出选项，可提供约四分之三的全日照水平的照明，通过连接的加湿和除湿系统控制湿度，以及使用CO2注入和集成红外气体分析仪控制CO2浓度。 第二对腔室的配置与上述配置相同，但缺少高光输出选项和对CO2的控制。 收购这些室将扩大未来的研究工作约翰V.H.作者：Jerry G. Chmielewski; and Dean M. DeNicola在生物系。 成长室还将扩大滑石大学的主要使命卓越的本科教育在课堂上，实验室和独立的教师监督的学生研究。 这些分庭将根据调查人员的主要研究兴趣，提供研究各种项目的能力。所有拟议研究的目标是提高我们对生物系统中机械关系的理解。 康斯特布尔博士的研究解决了在CO2浓度升高时硝酸盐和碳同化之间的机械关系，这将提高我们对植被对CO2浓度升高的长期生长反应的预测能力。 Chmielewski博士的研究发展了对杂草和非杂草紫菀物种之间生殖进化趋势的理解。DeNicola博士的调查旨在建立一个基于生长形式和潜在殖民类群的底栖藻类演替预测模型;以及（ii）确定酸性矿山排水（AMD）对底栖藻类群落结构和初级生产的影响，以改善AMD影响溪流的修复工作。
