Final answer:
The turnover rate can indicate island size and compositional stability.
Step-by-step explanation:
The turnover rate can indicate island size and compositional stability. According to the equilibrium theory of island biogeography, the turnover rate is the balance between the rate of colonization of new species and the rate of extinction of species already present on the island. A larger island with more resources and habitats can support a higher turnover rate, while a smaller island with limited resources may have a lower turnover rate.
