Abstract:Saurophagy constitutes an important source of mortality among lizards and has been reported for the genus Tropidurus. However, the extension of this behavior remains unknown. Herein, we record the predation of T. jaguaribanus by its congener T. hispidus. This is the first report of saurophagy among different species of syntopic Tropidurus. Furthermore, whereas published records of saurophagy tend to be directed against juveniles, this case involved two adult individuals. Keywords: Predation, mortality, agonist… Show more
Documented information on lizard diets have contributed to a better understanding of species ecology, strategies, and predator-prey interactions. For Venezuela, the information continues to be very discreet. Two cases of interactions are anectodally reported here: firstly, the predation of Gonatodes albogularis by Tropidurus hispidus, and secondly, the occurrence of a leaf litter lizard Gymnophthalmus speciosus subjugated by a Neuroptera of the genus Myrmeleon in its larval stage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
