摘要
We study persistence in general seasonally varying predator prey models. Using the notion of basic reproduction number R-0 and the theoretical results proved in Rebelo et al. (2012) in the framework of epidemiological models, we show that uniform persistence is obtained as long as R-0 > 1. In this way, we extend previous results obtained in the autonomous case for models including competition among predators, prey mesopredator superpredator models and Leslie Gower systems.
