Knowledge graph centered on Long-term nitrogen manipulation experiment with plant community monitoring with 74 nodes and 180 connections. Top connected: Hummingbird, Bombus, Ipomopsis, Ligusticum porteri, Delphinium.
A controlled field experiment testing the effects of nitrogen addition and reduction on plant community composition over 8 years. Annual percent cover monitoring tracked responses of invasive and native species.
Synthesized from method descriptions across 12 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. The protocol was originally introduced by The response of four subalpine forbs to supplemental nitrogen within different soil moisture environments (2009). Implementations in other papers (listed below) may differ.
