Figure 2. Photographs of canopy samples described in Fig. 1.

(A) Canopy-original samples consisted of undisturbed areas of epiphyte mats (EM), marked at both ends. (B) Canopy-severed samples were branch segments taken from nearby source trees; segments with intact EM were hung with strings below branches that were adjacent to the canopy-original samples. (C) Ground-perched samples were placed on the ground, with intact EM on branch substrates. (D) Ground-flat samples were placed on the ground, with EM removed from their branch substrate and laid flat to have direct contact on the forest floor. Ground-original treatments (not pictured here) were collected from the forest floor, with the O-layer removed. All photos were taken at the beginning of the experiment (28 Sept 2012) except for ground-perched (C), which was photographed on 23 April 2013. Photo credit: N Nadkarni.
