Abstract：
With the help of a continuation theorem based on Gaines and Mawhin＇s coincidence degree, easily verifiable criteria are established for the existence of multiple positive periodic solutions of delayed predator-prey systems with type IV functional responses on time scales. Our results not only unify the existing ones but also widen the range of applications. Copyright © 2012 Shengbin Yu et al.
