First of all, you need to know that the island community is a term that refers to the areas formed by islands and all the factors that compose it, such as the fauna and flora present there. These communities can be affected by several physical and biological factors that modify the ecological tolerance of the place. In general, we can say that small islands away from the continent have a lower ecological tolerance due to the isolation in which they find themselves. This is because distance limits the integration between ecological factors.
