<h3>Pairwise Model Prediction Of Community Dynamics</h3>

<p class="prewrap interaction-description">Time-resolved measurements of lower-order assemblages showed that pairwise interactions, rather than higher-order interactions, are major drivers of the synthetic gut community dynamics.</p>
<p class="prewrap interaction-description">A generalized Lotka-Volterra model trained on monospecies and pairwise time series predicted much of the tested 11- and 12-member community dynamics; additional full-community training improved predictions. PARTIAL - model success supports important pairwise effects in these conditions, not absence of higher-order effects, perfect prediction or universal acetate cross-feeding. Abundance inputs combined 16S proportions with OD600, not direct viable-cell counts.</p>

<p class="prewrap interaction-description">The inferred human-gut SynCom network contains many negative interactions and frequent positive interactions that form the interaction topology of the community.</p>
<p class="prewrap interaction-description">The fitted 12-species gut network contains frequent negative and positive interaction coefficients, including coupled positive/negative pairwise motifs. These are effective ecological effects inferred from abundance dynamics. Their signs do not uniquely identify nutrient competition, cross-feeding, niche partitioning or molecular mechanisms; conditioned-medium and metabolomics results provide complementary but imperfect support.</p>

The CH-ER pair provides an experimentally coexisting example. PARTIAL - the mathematical mechanism is model-bounded; neither its molecular mediator nor universal stability of the full 12-member system follows from this analysis.</p>

Which molecular mechanisms realize the inferred signed interactions and feedback?
</h3>
<p class="prewrap">Remove the analytical inference-to-topology arrow, but retain topology-to-coexistence as a model-bounded causal mechanism. Acetate in the cited passage is a prior-literature example; separate metabolomics cultures supplemented ER and FP with acetate, which does not prove cross-feeding throughout this graph. Co-consumption/secretion only yields an ecological effect when relevant substrates limit growth, and conditioned-medium signs do not always match inferred coefficients. Higher-order effects, parameter uncertainty and OD-scaled abundance remain limitations. Canonical NCBITaxon:2 is only an aggregate placeholder for the 12-species experimental roster; #1548 tracks its grounding and non-graph metadata. No original figure pixels, separate supplements, raw data or executable model reproduction was performed.</p>
