Neutel & Thorne (Ecology Letters, 17:651–661, June 2014) provide an approximation for the leading eigenvalue of a food web community matrix involving coefficients of its characteristic polynomial. Though valuably incorporating three‐way species interactions, two critical problems emerge when one considers the dimensions of the system, calling the approach's accuracy and precision into question.
