Monte Carlo Simulation in Lattice Ecosystem: Top-Predator Conservation and Population Uncertainty
- 362 Downloads
The conservation of biodiversity is one of the most important problems in this century. Under human management, ecosystems suffer perturbations or disturbances. The investigation of perturbation experiments is essential to conserve species and habitat. We carry out Monte-Carlo simulations on finite-size lattices composed of species (n ≤ 4). The value of mortality rate m of top predator is altered to a higher or lower level and a fluctuation enhancement (FE) is explored. Here FE means an uncertainty in population dynamics. It is found for that FE is observed when m is decreased. Namely, when we protect the top predator, its population dynamics becomes very difficult to predict.
