Controlled - environment chambers will be obtained for use in botanical studies. Research by A.J. Shaw will investigate mechanisms of sex ratio determination in natural populations of bryophytes. Single spore cultures will be isolated from a population and differences between male and female gametophytes in ecologically important traits will be assessed. J.M. Bernard will investigate the effects of temperature on life history characteristics, including inorganic nutrition and carbon allocation, in wetland plants, Growth chambers will allow Dr. Bernard and collaborating undergraduate students to expand previous field studies by testing hypotheses under controlled conditions. I.A. Tamas will investigate mechanisms underlying the effects of indoleacetic acid (IAA) on plant morphogenesis using transgenic tobacco plants. Dr. Tamas' work requires tissue culture under axenic conditions as well as the growth of transgenic whole tobacco plants. B.P. Smith will investigate interactions between environmental factors, such as humidity and parasitism by mites, in determining mortality in populations of mosquitoes. Dr. Smith's research requires close control of temperature, photoperiod, and humidity.

将获得用于植物学研究的受控环境小室。A.J.肖的研究将调查苔藓植物自然种群中性别比例决定的机制。单孢子培养将从种群中分离出来，并将评估雄配子体和雌性配子体在生态重要特征上的差异。J.M.Bernard将在湿地植物中研究温度对生活史特征的影响，包括无机营养和碳分配，生长室将允许Bernard博士和合作的本科生通过在受控条件下测试假设来扩展之前的实地研究。I.A.TAMAS将利用转基因烟草植株研究吲哚乙酸(IAA)对植物形态发生影响的潜在机制。塔马斯博士的工作需要在无菌条件下进行组织培养，以及转基因整株烟草的生长。B.P.史密斯将研究环境因素之间的相互作用，如湿度和蠕虫寄生，以确定蚊子种群的死亡率。史密斯博士的研究需要严密控制温度、光周期和湿度。
