BIOLOGY/ECOLOGY Research Goals You will explore two research questions: 1) What effects does island area have on species richness (species-area relationship), and 2) What effects does distance of an island from mainland have on species richness (species- distance relationship). 3) How do species dispersal abilities affect species richness on islands. EXCEL work and word submission 1. What is island biogeography? 2. What factors negatively affect island biodiversity? 3. What is the hypothesis of the experiment? 1 4.
