Investigating dietary resource utilization and head morphology of gape-limited predators can
provide a basis for understanding interspecific competition and species coexistence. For …

Filesnakes (Acrochordus arafurae) are large (to 2 m), heavy-bodied snakes of tropical
Australia. Sexual dimorphism is evident in adult body sizes, weight/length ratios, and body …

In aquatic natricine snakes, piscivorous species tend to have narrow streamlined heads,
while species that prey on frogs have broader heads. his pattern is thought to reflect the …

Competition for prey is thought to be important in structuring snake assemblages. However,
due in part to the secretive behavior and low detectability of many snake species, this …

Resource availability and accessibility are primary factors guiding the distribution and
abundance of organisms. For generalists, prey availability reflects both prey abundance and …

Niche partitioning is an important mechanism for allowing ecologically similar species to
coexist, contributing to biodiversity and the functioning of ecological communities. Species …

Sexual dimorphism is a common phenomenon among animals. The usual cause cited for
sexual dimorphism in animals is sexual selection acting through female choice or male …

The diversity of feeding mechanisms among predators reflects phenotypic modifications that
may improve feeding performance on a preferred prey type. I compared trophic morphology …

Phenotypic diversity, or disparity, can be explained by simple genetic drift or, if functional
constraints are strong, by selection for ecologically relevant phenotypes. We here studied …

In snakes, divergence in head size between the sexes has been interpreted as an
adaptation to intersexual niche divergence. By overcoming gape-limitation, a larger head …
