looking for a microcosmic system

[Chen]

Xin Chen Wrote: I am looking for an experimental system for testing a
hypothesis related to food web theory. This system should be a three-species 
food chain and have the following features: continuous-time population 
change, age-structure effects can be minimized, the influence of spatial 
elments on the temporal dynamics can be ignored, easy to monitor the 
population change. It will be highly appreciated if someone can provide 
advice concerning this issue.
