Document Summary
However: this is pattern description, not hypothesis testing. Given that any species is limited to certain habitat(s), if you increase the habitat variation in an area, species richness should increase too. Over small areas, this is simply true and can be observed casually with almost no effort. Each habitat climate can cater to a specific kind of species, eg boreal forest is habitat for boreal species. Increasing more of one habitat work better than just changing the climate, but changing climate will probably change habitat in some way. What would gradient of diversity look like if you randomly distributed species everywhere. What the world would look like you removed the process that you are studying. If both are the same, maybe the inference is wrong, what you are studying is wrong. Need to make a sensible null randomized model. Landlocked thrown into ocean nope, keep them within the coastlines.
