Fig. 4: Methodological schematic detailing the steps taken to reconstruct ancient food webs using the PFIM77.
From: Extinction cascades, community collapse, and recovery across a Mesozoic hyperthermal event
INPUT: (a) community occurrence data and associated trait combinations for each taxon/guild occurrence; (b) trait-based feeding rules that parameterise PFIM for reconstructing empirical food webs across all intervals. MODEL: (c) explanation of how the model works and which methods of trophic network reconstruction were used in this study. OUTPUT: (d) Details of visualised trophic network output and (e) network metrics and motifs quantified by the model that were used in this study.
