Using metabolic tracer techniques to assess the impact of tillage and straw management on microbial carbon use efficiency in soil

Tillage practices and straw management can affect soil microbial activities with consequences for soil organic carbon (C) dynamics. Microorganisms metabolize soil organic C and in doing so gain energy and building blocks for biosynthesis, and release CO2 to the atmosphere. Insight into the response of microbial metabolic processes and C […]

Multiple-Element Isotope Probes, NanoSIMS, and the Functional Genomics of Microbial Carbon Cycling in Soils in Response to Chronic Climatic Change

For the past several decades, connecting biogeochemistry and microbial genomics has been a high priority in microbial ecology. Yet, techniques that actually link element flow and genomic information are scarce. In this project, we are using the Chip-SIP method to measure isotopic composition of major elements (C, N, H, and […]

Seasonal patterns in microbial communities inhabiting the hot springs of Tengchong, Yunnan Province, China

Studies focusing on seasonal dynamics of microbial communities in terrestrial and marine environments are common; however, little is known about seasonal dynamics in high-temperature environments. Thus, our objective was to document the seasonal dynamics of both the physicochemical conditions and the microbial communities inhabiting hot springs in Tengchong County, Yunnan […]
