Fig. 4

Representation of the first two axes (CCA1 and CCA2) of the canonical correspondence analysis (CCA) of the bird assemblages with the forest structural variables surveyed from December 2015 to August 2017 at the piedmont Southern Andean Yungas forest, Jujuy province, Argentina, in the unburned reference site (R; green), close-burned site (QC; brown), and distant-burned site (QL; orange). Shown in parentheses after each axis is the percent of variability contribution of that axis. Blue arrows indicate the direction of the strength of the forest structural variables: ABM = basal area of standing dead trees (snags), AltM = height of standing dead trees (snags), ABV = basal area of live trees, AltV = height of live trees, Cob = canopy cover, and Vis = understory visibility. Bird species strongly associated with each axis are shown. Resolution of this image remains poor
