Transcribed Image Text:**Metapopulation Dynamics and Logistic Growth**
The ecologist Richard Levins realized that metapopulation dynamics amongst subpopulations are analogous to logistic growth for individuals within a single population. The analogy is summarized in this table:
| **Logistic Growth** | **Metapopulation Dynamics** |
|---------------------------------|-----------------------------------------------|
| **Unit of interest:** | Individuals in a population |
| | Patches in a region that can host subpopulations |
| **Model describes change in:** | Number of individuals, N |
| | Proportion of patches that are occupied, P |
| **Limit to growth:** | Carrying capacity, K |
| | All patches being occupied, P = 1 |
**Q4.7.** If 6 out of 10 patches have salamanders in them, what is the patch occupancy, P?
