Realized population change for long-term monitoring: California spotted owl case study

The annual rate of population change (λ_t) is a good metric for evaluating population performance because it summarizes survival and recruitment rates and can be used for open populations. Another measure of population performance, realized population change (Δ_t

Comparing estimates of population change from occupancy and mark-recapture models for a territorial species

Monitoring studies often use marked animals to estimate population abundance at small spatial scales. However, at smaller scal
