microbiota of males and females of Podarcis bocagei andPodarcis lusitanicus from Moledo.
Figure 6 : Boxplots depicting the significant differences in the
abundance of the main bacterial genera (> 1% of all
sequences) among species collected in Lisbon (Podarcis siculus,
Podarcis virescens and Teira dugesii)
Figure 7 : Boxplots depicting the abundance of the main
bacterial genera (> 1% of all sequences) for which
species*sex was significant in species collected from Lisbon
(Podarcis siculus , Podarcis virescens and Teira
dugesii ).

bacterial alpha-diversity (Shannon index) for Podarcis siculus. The
coloured area represents the 95% confidence limit.
