Knowledge graph centered on Nanda-Hamner experiment (Drosophilidae) with 21 nodes and 56 connections. Top connected: Atriplex canescens, Lepidoptera, winter survival, Drosophila melanogaster, A. fabae.
Experimental protocol to test for circadian rhythmicity in photoperiodic responses by exposing insects to constant day length (12h) with varying night lengths to create non-24h photoperiods, then measuring diapause induction rates.
Synthesized from method descriptions across 1 paper using this protocol.
Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Nanda-Hamner Curves Show Huge Latitudinal Variation but No Circadian Components in <i> Drosophila Montana </i> Photoperiodism (2021), Journal of Biological Rhythms. Implementations in other papers (listed below) may differ.
