**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?
