3.2 Phylogenetic and functional community structures
At the landscape scale, SES.MPD values were less than zero in all forest
types, while SES.MFD values were close to (but greater than) zero. At
the site scale, SES.MPD values were significantly lower than zero in all
forest types (t-test, t =-3.719, df =17, p=0.002; t-test,t =-2.851, df =17, p=0.011; t-test, t =-3.281,df =17, p=0.004), and there was no significant difference in the
SES.MPD values among the three forest types (one-way ANOVA, df =2,F =0.178, p=0.838). SES.MFD values were close to zero in forest
types (Wilcoxon test, V =111, p=0.284; t-test, t =-0.798,df =17, p=0.436; t-test, t =-0.609, df =17, p=0.551),
and there was no significant difference in SES.MFD among forest types
(one-way ANOVA, df =2, F =0.589, p=0.559, Fig. 5).
The K values of body length, tail length, hind foot length and ear
length were all less than 1, indicating weak phylogenetic signals of
these functional traits
(i.e.
trait convergence). D statistics revealed weak phylogenetic signals for
foraging stratum and daily activity
(0<Dobs<1; i.e. trait convergence)
but strong signals for the other four binary traits
(Dobs<0; i.e. trait conservatism). The
distributions of foraging stratum and daily activity differed
significantly from random distributions along the phylogeny, while only
that of daily activity differed from a Brownian distribution (Table S1).
