Drymarchon corais and Caiman crocodilus are reported here using different feeding behaviors for consuming poisonous toads of the genus Rhinella (Bufonidae). Drymarchon corais was observed feeding on specimens of Rhinella diptycha without avoiding contact with the parotoid macroglands, suggesting that this snake species is immune to toad toxins. Caiman crocodilus was recorded avoiding contact with the parotoid macroglands of specimens of Rhinella marina by consuming only the front and rear legs, suggesting that this caiman...

Data for: Determinants of resource use in lizard assemblages from the Neotropical semiarid Caatinga

Non-sessile animals could partition the use of resources in different axes, reducing the effects of competition and allowing coexistence. Here, we investigated the spatial and trophic niche dimensions in four lizard assemblages in the Neotropical semiarid Caatinga to investigate the determinants of resource use and the extent which lizards partition their niches. We sampled each lizard assemblage once, for ten days, in the dry season of 2017 and 2018. In two lizard assemblages, we detected...
