Document Summary

Other assumptions: population is closed (no immigration/emigration, vital rates are constant (no demographic or environmental stochasticity, vital rates are not dependent on abundance (not density dependent) can add migration, stochasticity and density dependence to stage-structured model. Difference between age-structured and stage structured models: type of transition the number and type of transitions possible for an individual in a given age or stage class: age-structure, 2 types of transitions. Individuals may get older (move to next class: may produce offspring (contribute to first age class) 2nd ed: stage-structure, 4th transition -> individual stay in the same stage after a time step. If it were possible for a small stage individual to go into large stage in. 1 time step without passing the medium stage then there would be: no nonzero element in the second column & last row, arrow going from small to large.
