Before revision:  Our framework highlights how to combine data types in dynamical models for multiple species , and may be extended to other biotic interactions for which data on both interaction rates and population counts are available .
After revision:  Overall, we show that under process stochasticity in interaction rates, interaction data might be essential to obtain identifiable dynamical models for multiple species , and may be extended to other biotic interactions for which data on both interaction rates and population counts are available .
