Method synopsis
Generation of null models that maintain interaction totals per species while randomizing interaction patterns, followed by permutation tests to assess significance of observed network metrics relative to abundance-based expectations.
Synthesized from method descriptions across 3 papers using this protocol.
Procedure from a recent peer-reviewed implementation
Random loss of species from weekly and season-long networks simulated using secondary extinctions approach. Simulations removed species from networks in random order, calculating remaining species when interactions were lost altogether. Each simulation scenario run 100 times for each network and robustness values averaged across runs.
Quantities: 100 simulation runs per network per extinction scenario, applied to all 45 networksDuration: Computational analysis performed on all constructed networksConditions: Species considered extinct when they lost all interaction partners
