Hui-ling Liao

Project type

FICUS Research

As the critical members of forest microbiome, ectomycorrhizal fungi (EMF) play important roles in forest ecosystems. EMF provide their tree hosts with macro- and micronutrients in exchange for…

Mineralogy exerts control on organic molecules zonal structuring and reordering

Lead Institution

Environmental Molecular Sciences Laboratory

Principal Investigator

Odeta Qafoku

Organic C preservation in soil environments is predominantly driven by organic matter: soil mineral interactions. Yet, mechanistic uncertainties remain, namely how spatial variation in mineralogy…
