4. DISCUSSION
We found that skull size and inter-sex morphology was significantly
different, variation that can be associated with the diet of the
selected bat species; possibly as a result of differences in energy
requirements during the reproductive season (de Camargo & de Oliveira,
2012). Although sexual dimorphism has been relatively well documented in
vespertilionid bats, being the females larger and heavier than males
(Bornholdt, Oliveira, & Fabian, 2008), in phylostomid bats this
information is less documented despite it being the most diverse and
distributed family in the Neotropics (Gardner 2008). However,
López-Aguirre & Pérez-Torres (2015) identified that Artibeus lituratus
females in Colombia had greater fluctuating asymmetry in the
splanchnocranium presenting a differential on bite force.
