Abbreviations used (cf. Appendix 9): gr = ground level; ug = undergrowth (0 to 4 ±1 m); us = understoiy (4 ±1 m to c. 15 m); sc = subcanopy (c. 15-25 m); ca = canopy; used for species feeding at or near the foliage-air interface of canopy trees and emergent trees (>20 ±5 m); of = outer foliage; tt = treetops and bare or dead snags; ai = airspace. Note: For the Chi-squared test of (b) I combined the categories 'gr' with 'ug,' W with 'sc,' as well as 'ca' and 'tt + of with 'ai', in order to avoid the expected count of some cells in the contingency table being less than five. No lumping of stratum categories was necessary in (a); see text for details. 89.
