Disadvantages of Preferential Dispersals in Fluctuating Environments
Satoru Morita, Jin Yoshimura
It has not been known whether preferential dispersal is adaptive in fluctuating environments. We investigate the effect of preferential and random dispersals in bet-hedging systems…
Analytical solution of stochastic model of risk-spreading with global coupling
Satoru Morita, Jin Yoshimura
We study a stochastic matrix model to understand the mechanics of risk-spreading (or bet-hedging) by dispersion. Such model has been mostly dealt numerically except for well-mixed…
Analytical Solution of Metapopulation Dynamics in Stochastic Environment
Satoru Morita, Jin Yoshimura
We study a stochastic linear discrete metapolulation model to understand the effect of risk spreading by dispersion. We calculate analytically the stable distribution of population…
Population Uncertainty in Model Ecosystem: Analysis by Stochastic Differential Equation
Satoru Morita, Kei-ichi Tainaka, Hiroyasu Nagata +1
Perturbation experiments are carried out by contact process and its mean-field version. Here, the mortality rate is increased or decreased suddenly. It is known that the fluctuatio…
