5. The effect of network types and disturbance on specialisation of
ant-plant interactions as measured using four different specialisation
indices. (a) H2’ network specialisation. (b)
Standardised effects size of deviation of observed H2’
from that generated using a null model (H2’ z-score).
(c) Degree of ant specialisation on plants in terms of plant partner
phylogenetic relatedness (dsi*ants). (d) Degree of plant specialisation
on ants in terms of ant partner phylogenetic relatedness (dsi*plants).
Different letters indicate significant differences in specificity
between network types or levels of disturbance, although note that for
panel (a) there is also a significant interaction involving interaction
type (See Fig 4a), and so the main effect should be interpreted with
caution.
