Knowledge graph centered on quadrat sampling (Asteraceae) with 70 nodes and 156 connections. Top connected: Ligusticum porteri, Delphinium, Potentilla, Lepidoptera, Erigeron.
Plant cover measured using 1 m² quadrats divided into 1 dm² cells, counting filled cells to nearest 0.25 dm². Height measured to maximum plant extension. Volume calculated as cover × height/10.
Synthesized from method descriptions across 4 papers using this protocol.
Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Chronic, low-level nitrogen deposition enhances abundances of ant-protected herbivores inhabiting an imperiled foundation species (2021), Acta Oecologica. Implementations in other papers (listed below) may differ.
