e Dear Editor,
Elizabeth Green has submitted her article titled 'The Effect of a "Smart"
Predator in a One Predator, Two Prey System' to your journal for publication. I strongly support its publication.
The manuscript was part of the result from her participation in our 2002 summer REU program and from her honors thesis at UNL, which received the highest distinction award from the university.
I was her REU advisor and then followed it up to be her honors thesis advisor. The result presented in her manuscript is highly original. It is my intention to eventually make the presentation suitable for submission to a regular research journal. Although unnecessary, let me describe briefly the problem studied in her manuscript.
The problem is about modeling and analyzing polyphagous predation in mathematical ecology. It is a well-known principle that predation efficiency destabilizes predator-prey equilibrium into limit cycle in predator-prey models, with efficiency being directly associated with the existence of stable population cycles. Beth's model contains one predator and two preys.
She first incorporated a more realistic assumption into a standard predator-prey model by assuming that the predator partitions its hunting time according to the relative abundance of the preys rather than hunts them indiscriminately. Assuming the predator is efficient separately on each of the two preys when the other prey is absent, one of her questions is to ask if the joint predation is efficient as well? Contradicting to my intuition Beth made a very surprising discovery that it needs not to be case due to the presence of the other prey as a distraction. She made another important discovery that one cannot aggregate the three-species system into a two-species model as a means of modeling simplification. She demonstrated that when both individual predations are efficient, the joint predation dynamics can be chaotic, a characteristic unique only for autonomous systems of 3-dimension or higher.
Please don't hesitate to contact me if you have more questions.
Sincerely,
Bo Deng
