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.
