主讲人:Mary Beth Adams 教授主持人:周小奇 教授时间:10月10日 13:00 讲座地址:资环楼435室报告摘要:In this presentation, Dr.Adams present results of study designed in the 1990s to investigate the impactof long-term acidic deposition on nutrient cycling and forest. To address theseconcerns, the Fork Mountain long-term soil productivity (LTSP) experiment wasinitiated in 1996 at the Fernow Experimental Forest, West Virginia. Thereplicated experimental design consists of 16 plots (0.2 ha) that receive oneof four treatments: (1) whole-tree harvesting (removal of all abovegroundbiomass, WT plots); (2) whole-tree harvesting + ammonium-sulfate fertilization(WT + NS plots); (3) whole-tree harvesting + ammonium-sulfate fertilization +dolomitic lime (WT + NS + Lime plots); and (4) untreated reference plots. Thistalk presents forest floor and soil chemistry responses after ∼25 years of treatment and evaluates temporal changes. Inaddition, changes in forest stand composition and productivity in these plotsare also examined.报告人简介: Dr. Adams is Research Soil Scientist (Emeritus) with the US Forest Service, and also holds an Emeritus Graduate Faculty position with the West Virginia University Davis College of Agriculture, Natural Resources and Design. She earned a B.S. and M.S. in Forestry from Purdue University, and a Ph.D. in Soil Science and Forestry from North Carolina State University. Mary Beth’s research interests include understanding how water and nutrients move through forest ecosystems in response to various stressors, and using that understanding to sustain the productivity of forest ecosystems. Much of her work has been conducted on the Fernow Experimental Forest near Parsons, WV, where she served as Research Project Leader and Scientist for 20 years. She specializes in large, long-term experiments, and is co-Principle Investigator on studies supported by the National Science Foundation. She has published more than 180 scientific articles, served on many graduate committees at WVU and other institutions, served on advisory committees, and has been an editor for several significant journal volumes and books. Although retired, she continues to work on her long-term research studies, mentoring younger scientists, and remaining active in professional activities. She is an activemember of the Soil Science Society of America, Society of American Foresters,Association for Women in Science, and has been honored as a Fellow of the SoilScience Society of America, a Distinguished Alumnus of Purdue University’sCollege of Agriculture (2016), and an Inspiring Woman for OutstandingScientific Achievement (2019), and for Outstanding Mentoring by the NorthernResearch Station of the Forest Service. She also received the LifetimeAchievement Award from the Purdue University Department of Forestry and NaturalResources in 2020. She presented the S.A. Wilde Distinguished Lecture in ForestSoils at the 2021 Soil Science Society of America annual meetings.
