文摘
- •
We introduce a new concept to measure the success of a biological control.
- •
We show that the three species model proposed in “The role of top predator interference on the dynamics of a food chain model” by Upadhyay et al. [64], and its spatially explicit version, can blow-up in finite time, for sufficiently large initial data.
- •
We show predator interference is the sole factor in inducing this blow-up.
- •
Based on our results we propose that generalist predator interference might be a cause of their success.
