Viviparity
- Phylogenetic analysis of maximal oxygen consumption during exercise (V̇O2,max) and ecological correlates among lizard species
Summary: Among species of lizards, helodermatids, varanids and skinks (which are mainly active foragers) have relatively high maximal aerobic capacity during forced exercise (V̇O2,maxV̇O2,max), whereas viviparous species have relatively low V̇O2,maxV̇O2,max.
- Maternal basking regime has complex implications for birthdate and offspring phenotype in a nocturnally foraging, viviparous gecko
Summary: Basking opportunity strongly affects maternal thermoregulation and gestation length in a ‘nocturnal’ gecko; spontaneously born offspring from a cool regime are small, but consistent phenotypic effects from delayed parturition are lacking.
