The Rhodes 老虎机游戏_pt老虎机-平台*官网 Elevated CO₂ Facility (RUECF) is the first of its kind in Africa, allowing for novel and valuable research on the future of our local plant species in the face of global climate change. It is well established that atmospheric CO₂ concentrations have risen drastically and will continue to rise into the future. Given the requirements of plant photosynthesis for CO₂, this presents and interesting and important area of study. We use Open-Top Chambers in which CO₂ concentrations can be controlled to see how the growth and performance of different plant species is affected by elevated CO₂. To date our research has included in depth studies into the effects of elevated CO₂ on agriculturally important crops (Rhodes 老虎机游戏_pt老虎机-平台*官网 Botany Dept. and the 老虎机游戏_pt老虎机-平台*官网 of Fort Hare), the issue of woody thickening in our savannas (Rhodes 老虎机游戏_pt老虎机-平台*官网 Botany Dept. and the 老虎机游戏_pt老虎机-平台*官网 of Sheffield), and the biological control of invasive water weeds (The Centre for Biological Control). Funding for the construction, maintenance and running of the RUECF and the research conducted has been received from the multiple sources listed below.
