| Abstract: | Two discrete population models, one with stochasticity in the carrying capacity and one with stochasticity in the per capita growth rate, are investigated. Conditions under which the corresponding Markov processes are null recurrent and positively recurrent are derived. |
| Keywords: | Markov processes Invariant measures Population Dynamics Non-linear Stochastic Difference Equations Recurrence |
