Species specialisation metric
The degree of specialisation differed considerably among the species in the three forest sites within the Asenanyo Forest Reserve. The majority of the liana species (edge: 61.5 %, interior: 55.9 %, deep-interior: 63.3 %) had significantly higher degree of specialisation than that of the respective null models (Appendix 3). Correspondingly, the degree of specialisation varied widely among the species in the forest sites of the Suhuma Forest Reserve. Most of the species in edge (58.1 %) and deep-interior (65.0 %) sites were significantly more specialised than expected by chance. The minority of the tree species in the three sites of Asenanyo and Suhuma Forest Reserve were more specialised than expected by chance (Appendix 4). About 43 % of liana species in interior site had significantly higher degree of specialisation than the null model. In the Asenanyo Forest Reserve, the proportion of tree species with higher specialisation than their null models (edge: 42.1 %, interior: 42.9 %, deep-interior: 37.1 %) was lower than the proportion of tree species that did not show higher specialisation than expected by chance. A similar trend was recorded in the Suhuma Forest Reserve (edge: 36.5 %, interior: 39.1 %, deep-interior: 45.7 %). Generally, higher proportions of lianas than tree species showed higher specialisation than the null models.
