Data from: Evolution of stenophagy in spiders (Araneae): evidence based on the comparative analysis of spider diets

Stano Pekár, Jonathan A. Coddington & Todd A. Blackledge
Stenophagy (narrow diet breadth) represents an extreme of trophic specialization in carnivores, but little is known about the forces driving its evolution. We used spiders, the most diversified group of terrestrial predators, to investigate whether stenophagy 1) promoted diversification, 2) was phylogenetically conserved and evolutionarily derived state, and 3) was determined either by geographical distribution and foraging guild. We utilized published data on the prey of almost 600 species. Six categories of stenophagy were found:...
