“…Like in most anurans, the SVL of the female B. gargarizans exceeds that of the male B. gargarizans , and this finding is in line with those observed in previous studies on this species [ 18 , 27 , 34 ]. Previous studies have revealed that sexual size dimorphism (SSD) may be related to age structure, age at sexual maturity, growth rate, and fecundity [ 2 , 35 , 36 , 37 , 38 , 39 , 40 ]. For the B. gargarizans , males reach maturity one year earlier than females [ 34 ].…”

Sexual dimorphism is often considered to be the result of differences in the intensity of sexual selection between sexes. From this point of view, the sexual dimorphism of the limb bones of the Bufo gargarizans in southwest China was studied. Results showed that the fore- and hindlimb skeletons of this species were sexually dimorphic in anatomy. The humerus, radioulna, and total lengths of the forelimb skeleton of males were substantially longer than those of females, but the hand length of males was smaller than that of females. Several other features of males, such as deltoid and medial crest areas and humerus and radioulnar weights, were also significantly larger than those of females. The femoris, tibiofibula, talus–calcaneus, and foot lengths; total hindlimb skeleton length; and femoral upper crest areas of males were significantly greater than those of females. However, no significant intersexual difference in femoris and tibiofibular weights was observed. These findings suggested that robust forelimb bones and long hindlimb bones could contribute to the mating success of males; if so, sexual selection promotes the evolution of sexual size and shape dimorphism in the limb bones of the B. gargarizans.

“…Due to its abundance in natural and urban environments, the common toad has been the subject of numerous morphological studies (Cadjenovi c et al, 2013;Gittins et al, 1980;Guillot et al, 2016;Reading, 1988;Reading, 1991;Tomasevic et al, 2007). Previous studies have reported female-biased SSD (Cvetkovi c et al, 2003;Cvetkovi c et al, 2005;Cvetkovi c et al, 2009;Ergül Kalayci et al, 2019;Tomaševi c et al, 2008). However, there are no reports to concern SShD describing by data obtained in traditional morphometric methods.…”

Differences in male and female traits (sexual dimorphism [SD]) are widespread in animals. Dimorphism in morphological characters evolves under the effect of environmental and genetic factors and is shaped by natural and sexual selection. In this study, intersexual differences in size and shape in common toad, Bufo bufo, populations in Turkey were investigated. For this, linear measurements of 27 body‐related morphometric characters in a sample of 140 individuals (70 males and 70 females) were compiled. The data were analyzed using univariate and multivariate statistical methods. The results show SD in body size with females having larger body size, a trait related with fecundity and thus probably under sexual selection. Body shape differences, which are associated with head width and dorsal head, are likely to prey size. Male‐biased differences observed in nasal characters and tympanum may also be associated with sexual selection (male–male competition). Our findings are consistent with previous studies of major of Anura and support a role for selection pressures acting differentially upon individuals from both sexes, resulting in the evolution of sexually dimorphic traits.
