Just as we can use metapopulation models to study the probability of regional extinction, we can also study regional abundance and regional abundance trends.

This model simulates animal metapopulations in spatially explicit landscapes, and includes environmental stochasticity.

2f. [thought question] Is it possible for r maxrmax to be positive and yet for the total regional abundance to exhibit a persistent declining trend? Explain your reasoning, using at least one biologically realistic example. You can use the agent-based metapopulation model in InsightMaker to help test your ideas, but this is not required.
