AB  - We used geometric morphometric techniques to examine variability in Serbian red fox (Vulpes vulpes) crania. Male crania are about 5% larger than female ones and sexual size dimorphism (SSD) was significant. Also, significant cranial shape differences were found between the sexes. Males are characterized by reduced basicranial, but broader rostral and zygomatic regions. Although a slight and significant allometric effect was detected and larger specimens are smaller in the region of basicranium, cranial sexual shape dimorphism (SShD) pattern is not influenced by SSD. As small to moderate SSD in canid species is a general characteristics of the family, additional studies are needed to determine whether basicranial reduction in males, i.e. its enlargement in females, could be an important feature in characterizing cranial SShD patterns in other Canidae members. While uniform considering size, the shape of Serbian red fox crania varies geographically, as well as depending on proportion of agricultural habitats. In comparison to those from central and eastern Serbia, specimens from the northern Serbian region Vojvodina (with higher proportions of agricultural areas) have more robust crania with shorter snouts and maxillae, larger palatine bones accompanied with anteriorly moved posterior edges of the canine alveolus and laterally expanded zygomatic arches. Encompassing mostly facial and temporal cranial regions these shape changes are probably related to diet differences, although genetic diversification cannot be excluded as a possible contributing factor.

AB  - Geometric  morphometric  approaches  were  employed  for  the  first  time  to  explore  skull  size  and  shape
changes  in  golden  jackal  (Canis  aureus)  from  Serbia.  We  examined  three  different,  but  connected  aspects  of
its  cranial  variability:  geographic  variation,  sexual  dimorphism  and  allometry.  To  elucidate  the  pattern  of
cranial  size  and  shape  variation,  we  analyzed  ventral  crania  of  subadults  and  adults  from  two  geographic
regions  of  Serbia.  For  both  age  groups  there  were  no  significant  size,  but  significant  shape  differences
between  golden  jackals  from  northeastern  and  central  Serbia.  The  observed  shape  differences  were  subtle,
probably  due  to  recent  range  expansion  of  this  species  in  the  Balkans  and  a  strong  founder  effect  in
the  newly  established  populations.  The  detected  significant  sexual  size  and  shape  dimorphisms  (SSD
and  SShD)  were  slight  and  more  evident  in  adult  crania.  Although  the  SShD  observed  in  adult  crania  is
influenced  by  SSD,  factors  responsible  for  the  non-allometric  component  of  shape  variation,  and  not  pure
size  differences  between  sexes,  are  those  that  are  most  important  for  generation  of  SShD  in  this  species.  A
monogamous  reproductive  system,  male  parental  care,  omnivorous  and  opportunistic  feeding  behavior
and  the  absence  of  division  of  labor  between  males  and  females  in  activities  other  than  parental  care,
could  all  be  related  to  the  driving  of  morphological  similarity  between  the  sexes.
