Stability and feedback levels in food web models

Ecol Lett. 2015 Jun;18(6):593-5. doi: 10.1111/ele.12416. Epub 2015 Apr 6.


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.

Keywords: Complexity; food webs; negative feedback loop; population dynamics; stability.
