Occurrence and evolution of cannibal behaviour in extant snakes. [PDF]
Biol Rev Camb Philos SocABSTRACT Extant snakes (Serpentes) are a highly diverse group of squamate reptiles, which have independently evolved key morphological adaptations to consume a large variety of vertebrate and invertebrate prey. While these predator–prey interactions have been widely addressed by several studies, little is known regarding the occurrence of cannibal ...

Hard Mating Aggregation as Evidence of Polyandry in the Red-Tailed Boa, <i>Boa constrictor</i> (Squamata: Boidae), in a Brazilian Caatinga Population. [PDF]
Ecol EvolThis study reports a reproductive aggregation of a female Boa constrictor with five males in the Brazilian Caatinga. The observation reinforces the evidence of a polyandrous system, favoring larger females that copulate with different males. Our record highlights the influence of sexual size dimorphism in the formation of aggregations.

When to shed? Patterns and drivers of time to first ecdysis in snakes. [PDF]
Ecol Evol, 2023 We assessed patterns in time to postnatal ecdysis in snake species, and related measures to various biological traits. Time to postnatal ecdysis can be shorter or longer than the ancestral state, which we estimated at 8–9 days, indicating that there are several competing drivers for time to postnatal ecdysis.

Fossil snakes (Squamata, Serpentes) from the tar pits of Venezuela: taxonomic, palaeoenvironmental, and palaeobiogeographical implications for the North of South America during the Cenozoic/Quaternary boundary [PDF]
PeerJ, 2018 Background Tar seep deposits in South America historically are well-known for their rich record of fossil mammals, contrasting with only a few formal reports of reptile remains. Here we report a new snake fauna recovered from two tar pits from Venezuela.
