报告人简介：

Saman Bowatte is a Professor at college of Pastoral Agriculture Science and Technology (CPAST) of Lanzhou University, China. Professor Bowatte received PhD in Soil Science from the Massey University, New Zealand in 2003, then moved to Nagoya University, Japan for Post-Doctoral fellowship before returned to Grasslands campus of AgResearch New Zealand in 2006 to work as a Soil Microbial Ecologist for 10 years. In March 2016 he joined Lanzhou University.

His research focus has been about understanding and manipulating plant-soil-microbe interactions in grazed pastures to improve grasslands productivity while minimizing environmental pollution. His research included understanding of (a) nitrogen dynamics in pastoral soils, (b) climate change impacts on grasslands, (c) greenhouse gas emissions and mitigation, and (d) molecular level understanding of soil microbial diversity and function. He was a first author or co-author over 40 refereed journal papers in wide variety of journals such as ISME Journal, Soil Biology and Biochemistry, Agriculture Ecosystems and Environment and Geoderma.

报告摘要：

Understanding the influence of plants and plant-soil microbe interactions is important for improving knowledge of nitrogen cycling and nitrous oxide (N₂O) production from livestock farming. In this lecture I would like to show that not only plant identity influence N₂O production in grassland soils but also grassland plants itself emit N₂O. Meanwhile, it is noteworthy that bacteria on the grass leaf surfaces can be a previously un-recognized source of N₂O emissions in grassland ecosystems.
