Sexual dimorphism in snake head/skull is poorly known, although analyses in other
vertebrate groups have already pointed this kind of morphological difference. Herein we …

Background Sexual dimorphism in size and shape is widespread among squamate reptiles.
Sex differences in snake skull size and shape are often accompanied by intersexual feeding …

Sexual dimorphism in snakes is generally described in association with body or tail size and
scale counts, with relatively few studies addressing intrasexual divergence in the skull. Here …

Sexual dimorphism in snakes has been mainly evaluated for size and number of some
morphological traits, but few studies address on sexual shape dimorphism. Here we …

Snakes have high morphological variation, including between sexes. Most of these
variations are evidenced only by linear measurements, which are generally restricted to size …

Dam constructions cause fundamental changes in the natural landscape, creating new
ecological and evolutionary challenges for aquatic organisms. In some cases, such water …

Sexual dimorphism is a common phenomenon among snakes, with female snakes being
larger than male snakes as a recurrent pattern. However, species that show male-male …

The head is the most important element in trophic ecology among snakes. Head shape is
affected by several factors, both intrinsic, such as size and sex, and extrinsic, such as …

The extensive lack of knowledge on the morphological aspects of South American
watersnakes includes a poor understanding of phenotypic parameters, intraspecific …
