Differences in Functional Trait Distribution between Inselberg and Adjacent Matrix Floras

Table 1

Inselberg insular guilds as defined by McGann [12].

Guild	Category of insularity
0	Never found on inselbergs, taxa restricted to the surrounding vegetation
1	Taxa always found in surrounding matrix but in low abundance on inselbergs
2	Ubiquitous taxa found equally on inselbergs or the matrix
3	Taxa common on inselbergs but occasionally found in the surrounding matrix
4	Taxa restricted to inselbergs on the New England Batholith but found in other habitats elsewhere
5	Taxa restricted to inselbergs and other rock outcrops throughout their distribution
6	Taxa restricted to granitic inselbergs throughout their distribution
