Stephanie Yarwood

About

Professor Stephanie Yarwood is a faculty member at the University of Maryland's College of Agriculture & Natural Resources, serving as a Professor and Graduate Director in the Department of Environmental Science & Technology. Her research focuses on the microbial ecology of soils across various ecosystems, including agricultural, wetland, forest, and urban environments. She seeks to understand how disturbances such as wetland restoration and agricultural management impact microbial communities and the implications of these changes on nitrogen cycling, greenhouse gas emissions, and carbon storage. Her broad goal is to uncover information that can improve soil management practices and contribute to a more sustainable future. Professor Yarwood's background includes a BA in English from Whitman College and a Ph.D. in Soil Science from Oregon State University. Her early work involved supporting her undergraduate studies through internships in soil microbiology and plant pathology labs. Her research has led to numerous publications and awards, including the Emil Truog Award from the Soil Science Society of America and the College of AGNR Paul R. Poffenberger Excellence in Teaching and Advising Award. She teaches courses such as Soil Microbial Ecology and Environmental Microbiology, and her work has significantly contributed to understanding soil microbial communities and their roles in ecosystem processes.

• Dark septate endophyte improves salt tolerance of native and invasive lineages of <i>Phragmites australis</i>

  The ISME Journal · 2020 · 99 citations

  Senior authorCorresponding

  Fungal endophytes can improve plant tolerance to abiotic stress. However, the role of these plant-fungal interactions in invasive species ecology and their management implications remain unclear. This study characterized the fungal endophyte communities of native and invasive lineages of Phragmites australis and assessed the role of dark septate endophytes (DSE) in salt tolerance of this species. We used Illumina sequencing to characterize root fungal endophytes of contiguous stands of native an…

  that enhance the interpretation of findings and facilitate model development. The protocols that we describe to measure soil, water, vegetation, and gases are also relevant for related disciplines such as ecology. Improved quality and consistency of data collection and reporting across studies will help reduce global uncertainties and develop management strategies to use wetlands as nature-based climate solutions.

• Earthworm assemblages in urban habitats across biogeographical regions

  Applied Soil Ecology · 2020 · 39 citations

  In urban landscapes, humans are the most significant factor determining belowground diversity, including earthworms. Within the framework of the Global Urban Soil Ecology and Education Network (GLUSEEN), a multi-city comparison was carried out to assess the effects of soil disturbance on earthworms. In each of five cities (Baltimore, USA; Budapest, Hungary; Helsinki and Lahti, Finland; Potchefstroom, South Africa), covering four climatic and biogeographical regions, four habitat types (ruderal,…

• Tracing sources of atmospheric methane using clumped isotopes

  Proceedings of the National Academy of Sciences · 2023-11-13 · 33 citations

  articleOpen access

  We apply a recently developed measurement technique for methane (CH 4 ) isotopologues * (isotopic variants of CH 4 — 13 CH 4 , 12 CH 3 D, 13 CH 3 D, and 12 CH 2 D 2 ) to identify contributions to the atmospheric burden from fossil fuel and microbial sources. The aim of this study is to constrain factors that ultimately control the concentration of this potent greenhouse gas on global, regional, and local levels. While predictions of atmospheric methane isotopologues have been modeled, we present…
