Birds and mammals generate heat to regulate body temperature, but most non-avian reptiles cannot. The discovery of endothermy during the reproductive period of a tegu lizard sheds light on the ...

For most animals, reproduction is straightforward: Some species lay eggs, while others give birth to live babies. But our recent research uncovered a fascinating mix between the two modes of ...

Lizards that produce live young are significantly more likely to be driven to extinction through climate change than those that lay eggs, new research suggests. The study, involving Nottingham Trent ...

Despite their cold-blooded reputation, tegu lizards boost their body heat while on the prowl for a mate, biologists report January 22 in Science Advances. Like other ectotherms, South American tegu ...

While there is no doubt that climate change is affecting many organisms, some species might be more sensitive than others. Reptiles, whose body temperature depends directly on environmental ...
