Huo, Hai-Feng Periodic solutions for a semi-ratio-dependent predator–prey system with functional responses. (English) Zbl 1079.34515 Appl. Math. Lett. 18, No. 3, 313-320 (2005). The author considers a class of nonautonomous semi-ratio-dependent predator-prey systems with functional response. By using the coincidence degree theory, he obtains sufficient conditions for the existence of a positive periodic solution.
