Phased protocol with explicit GO/NO-GO criteria and quantitative thresholds (ILS >30%, ΔLineages ≥2, quartet support ≥0.85, |Z|>3) that permit falsifiable assessment at each stage, reducing the risk of premature conclusion.
The hypothesis is firmly grounded in multispecies coalescent (MSC) theory and proposes falsifiable tests for each step of the causal chain (ILS, introgression, museomics, delimitation). The null hypotheses are explicit and the statistical thresholds (quartet support ≥0.85, ILS >30%, |Z|>3) are quantified, which is rare and commendable.
The hypothesis is unusually explicit regarding its own postulates and its known unknowns, and it proposes to test the feasibility of museomics (Phase 3) and the bias of the BFD under clonality (Phase 6) rather than presuming them. This constitutes a genuine methodological virtue.
Niche market with high value: the management of zebra and quagga mussels costs infrastructure operators (EDF, Veolia, US Bureau of Reclamation) more than €500M per year. A reliable delimitation test for the cryptic D. rostriformis complex enables treatments (biocides, coatings) to be targeted and costly regulatory errors to be avoided (e.g. discharge permits based on a misidentified species).
Falsifiable hypothesis with quantitative GO/NO-GO criteria (ILS >30%, DeltaLineages >=2, quartet support >=0.85, |Z|>3) — highly attractive to reviewers who value explicit high-risk/high-failure tests and 'kill-fast' designs.
