Question 2. Researchers tested the equilibrium theory of island biogeography using native and exotic plant communities found on multiple islands in Boston Harbor, Massachusetts, USA (filled circles, solid lines native species. open circles, dashed lines exotic species). Data were linearized via transformation with a log(x) function as needed. All regressions were statistically significant; reported P-values are for a test of equal regression slopes: 2.5 1.0 P >0.05 PExplanation / Answer
A. The number of species is higher on nearer and larger islands, because the inmigration rate is higher on nearer islands than on distant islands. Also, extinction is higher in smaller islands compare to large ones, so a larger island won´t have so much extinction of species.
B. The local plant species richness is higher when the area of the island is larger, as the graphic shows the richness increases when the area is larger. Also, the area adjusted richness on local plants is higher when the island is nearer mainland (or less isolated), as the graphic shows as the island is more isolated (or more far from mainland) the area adjusted richness diminishes.
C. This data supports the theory and it doesn´t depends if the species is native or exotic. The data supports the theory because it shows that the species richness is higher when the area of the island is higher and nearer to mainland, as explained in the previous question, which is exactly what the theory says. Also, the data doesn´t showed differences between native and exotic plants in both graphics.
D. N/A, there are no differences to explain, the exotic and native species never showed differences in both graphics.
