Why are the potential factors causing differences in species richness and/or abundance between edge and interior habitats? What are some of the things that explain this difference from the literature? Why was canopy cover presumed to have an effect on the species richness and abundance of arthropods in the forest? What other data that you collected might be useful in analyzing the arthropod species distributions? How would you analyze them? If you had null results (no significant difference between habitats and/or no strong correlations) for your experiment, what are the potential reasons? What are the differences, if any, in the types of species and their population sizes that occur in the two different habitats? How would you analyze this?
