摘要
During their lifetimes, individuals in 族群s pass through different states, and the notion of an occupancy time describes the amount of time an individual spends in a given set of states. Questions related to this idea were studied in a recent paper by Roth and Caswell for cases where the environmental conditions are constant. However, it is truly important to consider the case where environments are changing randomly or in directional way through time, so the transition probabilities between different states change over time, motivating the use of time-dependent stage-structured models. Using absorbing inhomogenous 馬可夫 chains and the discrete-time McKendrick-von Foerster equation, we derive explicit formulas for the occupancy time, its expectation, and its higher-order moments for stage-str
