What is it about?

Carnivorous rodents offer opportunity to probe details about the predatory attack not accessible in other carnivorous mammals. Differences found from comparisons between carnivorous grasshopper mice and omnivorous rodents show that the predatory attack of a carnivorous rodent differs substantially from that of an omnivorous rodent such as lab mice represents.

Why is it important?

The differences between the predatory attacks of carnivorous and omnivorous show a rejection of the null hypothesis that predatory attacks are similar among rodent species irrespective of their niche. Also rejected is the proposition that the aggressive and predatory attacks are connected to one another. The predatory attack operates independently of the aggressive attack and this allow selection to fine-tune the attack and thus increase success in capturing prey

Perspectives

I hope that researchers who investigate the predatory attack with omnivorous rodents recognize the problem of generalizing their findings to that of other carnivorous mammals.
