Research Highlight: Sensitivity and complacence of sedimentary biogeochemical records to climate-mediated forest disturbances

Novus steering committee members Jesse Morris (University of Idaho), Kendra McLauchlan (Kansas State University) and Phil Higuera (University of Idaho) recently published a paper in Earth-Science Reviews titled “Sensitivity and complacence of sedimentary biogeochemical records to climate-mediated forest disturbances.”

The paper focuses on using lacustrine sediment records to reconstruct biogeochemical responses to disturbance, specifically the ecosystem characteristics that lead to quantifiable changes in biogeochemical proxies following disturbance (sensitivity) or lack thereof (complacence). The authors built a framework using fire, logging, and bark beetle outbreaks as examples of disturbance events and their short- and long-term biogeochemical consequences. The paper also details appropriate sampling techniques for lacustrine sediment cores and data synthesis strategies for integrating multiple records across spacial and temporal scales.
