  1. We constructed fences using 2 x 2 x 2 factorial design to examine the effect patterns of food availability, predation and interspecific competition on population dynamics and spatial behavior of reed voles, microtusfortis. we expected to test two hypothesises : ( 1 ) availability of high quality food, predation and interspecific competition have independent and addictive effects on population system dynamics for small mammalia herbivore ; ( 2 ) availabiliry of high quality food could reduce home range and aggressive behavior level between individuals of microtine, predation and interspecific competition have independent effects on spatial behavior of microtine
