Location of Bulong Nature Reserve Mengsong.
The map was drawn in ArcGIS 10.2, and the boundaries were digitalized from the official map, representative purposes only herein. The old growth forests were textured, while the areas left blank were mainly covered by secondary forest and open land.

Spearman’s rank correlation coefficient of pairwise correlations of Host factors and Microsite factors.
Fig 3.
Correlations between epiphyte composition and host tree level environmental factors.
Left column: Epiphyte diversity (Shanon-Wiener index) of each host tree against the surveyed environmental factors. Right column: NMDS ordination biplots of the epiphyte community structure. The relationship with different environmental factors is indicated through the contour plots. Ordinations are for visualization only. All statistical tests of factor effects are conducted using mvabund (see text for details).

Profiles of the epiphyte-host tree network in Bulong Nature Reserve, Mengsong.
Links of between epiphytes and hosts are represented by lines, the widths of the connected rectangles represent the relative frequencies of epiphytes and hosts and the thickness of lines represents the relative frequency of the interactions. Epiphytes are the higher “trophic level”. Epiphyte and host tree names are given in the online electronic supplementary material (S3 and S4 Tables).
