What can you predict about the species Haddad and colleagues wanted to study, based on the size and vegetation of the habitat patches and corridors they used?

 . Examining habitat patches 14, 15, and 16, can you predict the type of comparison Haddad and his colleagues would make to determine whether corridors were important to the species studied? 

Specifically, what type of data would you collect, and in which patches, to determine whether corridors had an influence on the species of interest?
