Description
We examine long-term (1973-2003) population fluctuations and possible competitive interaction between five species of small mammals (Sigmodon hispidus, Microtus ochrogaster, Peromyscus lecuopus, Peromyscus maniculatus, and Reithrodontomys megalotis) that are syntopic in old-field habitat in northeastern Kansas. Previous studies describe the grassland community as a nonequilibrial community with annual and 3.5-year cycles. This project aims to simulate the cycles using Lotka–Volterra competitive models with time varying coefficients reflecting the impact of variation in temperature and precipitation on the population. If successful, the models can be used to predict the impact of severe weather changes and the climate changes on the rodent population dynamics. Furthermore, the numerical and analytical analysis of the models with constant coefficients may reveal possible limit cycles, extinction, survival, founder-control, and exclusion scenarios.

I'm interested in this project. What should I do next?
Now that UR-Linked has helped you to identify a faculty project that interests you and for which you might be
qualified, be sure to review
the essential steps in contacting a potential faculty mentor .
The Director of Undergraduate Research,
Dr. Jane Greer. , can provide you with further guidance about finding
and connecting with faculty mentors at UMKC.
Once you have reviewed the essential steps to prepare for connecting
with a potential faculty mentor, you can use the "Contact Details" for this project to connect with the faculty
member and to begin a conversation about how you might get involved.
