Species projected to increase in potential distributional area	651	1324	435	1504	406	1438

Numbers presented are average percent change relative to projected present potential distributional areas (standard deviations in parentheses). The final row presents numbers of species projected to increase in potential distributional area based on an average of all 4 future-climate scenarios, out of a possible 1804 species.
