Andrew Felton: 我主要从事干旱地区生态系统研究,研究重点是这些水资源匮乏的系统如何应对水资源变化。我的研究项目关注的是水资源的季节性来源如何影响大平原地区的植物生长。我们正在研究植物利用的水分来源,以及不同季节和年份(干旱或湿润年份)的水分来源变化。这项研究有助于我们了解干旱地区生态系统对气候变化的响应,以及这些系统在全球碳循环中的作用。在研究过程中,我们面临着许多挑战,例如学习新的编程语言、处理复杂的数据结构以及应对同行评审的反馈。但是,这些挑战也促使我们改进研究方法,最终使我们的研究成果更加可靠和全面。我们最近发表了一篇论文,对全球植物水分循环做出了重要贡献,量化了植物中储存的淡水量以及水分在植物中的传输时间。这项研究结果表明,尽管植物中的淡水储量相对较小,但其动态性强,是全球水循环中最快速的部分之一。这项研究对我们理解植被如何反馈到气候变化和水循环中具有重要意义。如果资源无限,我最想研究的是干旱地区在全球碳循环中的作用及其对气候变化的影响。这将涉及大规模的田间实验、先进的地球系统模型以及卫星数据的整合。

Shownotes Transcript

Dr. Andrew Felton is an Assistant Professor in the Department of Land Resources and Environmental Sciences within the College of Agriculture at Montana State University-Bozeman where he is Principal Investigator of the Felton Lab there. Andrew splits his time between teaching and his research lab. His research focuses on dry land ecosystems, which includes deserts, grasslands, and shrublands. Studies in his lab examine how these ecosystems function, what plants and animals are present, and how the ecosystems respond to changes in the availability of water. Climate change impacts the size of precipitation events and increases evaporation through higher temperatures, and Andrew’s lab is also working to understand the implications of these changes for ecosystems that are already water-limited. Living in Bozeman, Montana, Andrew enjoys spending time in the mountains and the beautiful National Parks nearby, including Yellowstone. In the winter, he is an avid downhill skier, and he likes to go rock climbing in the summer. His other hobbies include playing guitar, listening to music, reading, drinking great coffee, going out to eat, and spending time with family and friends. He completed his bachelor’s degree at the University of Minnesota, majoring in Biology, Society, and Environment. Afterwards, he was awarded his PhD in ecology from Colorado State University. Next, he worked as a Postdoctoral Research Scientist at Utah State University. He then received a U.S. Department of Agriculture-National Institute of Food and Agriculture (USDA-NIFA) Postdoctoral Fellowship Award, and he conducted research at Chapman University before joining the faculty at Montana State University. In our interview, Andrew shares insights and stories from his life and science.
