Utilizing herbarium specimens to quantify historical mycorrhizal communities

摘要

Premise of the StudyMycorrhiza are critical to ecosystem functioning, but a lack of historical baseline data limits our understanding of the long‐term belowground effects of global change. Herbarium specimens may provide this needed insight. However, it is unknown whether DNA of arbuscular mycorrhizal fungi (AMF) can be reliably extracted from vascular plant specimen roots.
