Gaston and Fuller (2009) potentially suggest that AOO is a better metric. But they are measuring different things.

http://enallagma.com/reprints/Swaegers%20etal%202014%20JEB.pdf uses just AOO as a proxy for range size.

Could also include both in the model, looking at corvif they don't seem that correlated.

EOO: extent of occurrence, the area that lies within the outermost geographic ilmits to the occurence of the species AOO: area of occupancy, the area within the outermost limits over which the species actually occurs (i.e. it will be equal or less to EOO)

Gaston and Fuller (2009): it is important to 1) distinguish the estimation of the distribution of a species from the measurement of its geographic range size 2) treat measures of EOO and AOO as serving different purposes (i.e. they are not more or less accurate ways of measuring range size) and 3) measure EOO including discontinuities in habitat or occupancy. They say the distinction between EOO and AOO is becoming blurred in many contexts, but particularly in that of threatened species assessments for Red Listing. The two measures serve different purposes and should not be regarded as alternatives that differ in accuracy. Lot's of papers/status use just EOO or use both.

Decision: Let's use both in the model.
