Study: Lizards bask for more than warmth
Keeping warm isn't the only reason lizards
and other cold-blooded critters bask in the sun. According to a study published in the May/June issue of Physiological and Biochemical Zoology , chameleons alter their sunbathing behavior based on their need for vitamin D.

Global survey of lizards reveals greater abundance of animals on islands than on mainland ecosystems
A comprehensive survey of lizards
on islands around the world has confirmed what island biologists and seafaring explorers have long observed: Animals on islands are much more abundant than their counterparts on the mainland.
Besides confirming that longstanding observation, the study signals an ...
Pressured by predators, lizards see rapid shift in natural selection
Countering the widespread view of evolution as a process played out over the course of eons, evolutionary biologists have shown that natural selection can turn on a dime -- within months -- as a population's needs change. In a study of island lizards
exposed to a new predator, the scientists found ...
