Knowledge graph centered on partial least squares regression (PLSR) (Salicaceae) with 70 nodes and 156 connections. Top connected: Spruce, Atriplex canescens, phenological mismatch, Asteraceae, Populus.
PLSR modeling approach using leaf spectral reflectance measurements to extrapolate functional trait values from subset of direct measurements to larger sample sizes. Ten-fold cross-validation used for model calibration.
Synthesized from method descriptions across 5 papers using this protocol.
Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Relaxation of the leaf economics spectrum within and across quaking aspen Populus tremuloides genotypes (2025), Oikos. The protocol was originally introduced by Integrating airborne remote sensing and field campaigns for ecology and Earth system science (2020), Methods in Ecology. Implementations in other papers (listed below) may differ.
