Estimates of amplification efficiencies (α) for all species in the mock communities.

Amplification efficiencies are relative to the Manila clam (R. philippinarum). The α parameter captures the log-ratio of amplification efficiency for a species relative to that of the reference species (here, Manila clam; see Shelton et al. [29] for full description of α). + Not present in sample data, α estimated from separate run of the quantitative model.
