Knowledge graph centered on Factorial drought and nutrient stress experiment (Brassicaceae) with 72 nodes and 176 connections. Top connected: Hummingbird, Delphinium, Potentilla, Lepidoptera, Delphinium barbeyi.
Greenhouse factorial experiment manipulating water availability (3 levels) and nutrient supply (2 levels) to test resource limitation effects on fitness components. Plants grown from field-collected seeds under controlled conditions with systematic treatment application.
Synthesized from method descriptions across 7 papers using this protocol.
Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Ecological factors influence balancing selection on leaf chemical profiles of a wildflower (2021), Nature Ecology & Evolution. The protocol was originally introduced by Resource availability alters fitness trade-offs: implications for evolution in stressful environments (2020), American Journal of Botany. Implementations in other papers (listed below) may differ.
