Figure S1
Contribution of multiple fragment combinations to regional species richness of forest specialists. Bat
species accumulation was calculated by combining site-wise data from 15 fragments in a random
order, while retaining information on the number of fragments, species and cumulative area.
Species richness estimates are shown for 10,000 random fragment combinations (grey points), and
for fragments added together in order of ascending (i.e. smallest first, red/black points) or
descending (i.e. largest first, blue points) area. Data are presented as plots of cumulative forest area
(a), cumulative number of fragments (b), and both (c).
Figure S2
Regional rarefaction curves for species (a,b) and alleles of the three study species (c-e) in continuous
forest (black lines) and fragments (coloured lines). Dotted lines represent the 95 % confidence limits
of the mean richness values for continuous forest sites - values that fall outside of these confidence
limits are significantly higher/lower. Rarefaction analyses were undertaken on all sites combined for
continuous forest and forest fragments utilising the same data used in other analyses.
Table S1 Mantel test correlation coefficients between genetic differentiation measured by Fst/1-Fst
and the following pairwise ecological or geographic distances for the three bat species: (i) bat
assemblage dissimilarity (Morita-Horn index), (ii) Euclidean geographic distance, and (iii) least-cost
distance. Mantel tests were calculated for these pairwise distances in Genalex v6.3 (Peakel and
Smouse, 2006). Probabilities of the correlation coefficients, calculated using 999 permutations, are
shown in parentheses.
