Canberra - Arabstoday

A new study in Biology Letters has found that warmer temperatures may make lizards smarter, even as past studies have linked a global decline in lizards to climate change. Looking at Australia\'s Eastern three-lined skink (Bassiana duperreyi), researchers found that warm temperatures during incubation not only resulted in larger individuals (a result confirmed in previous research) but perhaps more clever ones as well. To test the lizards\' smarts, scientists incubated two sets of lizards: 9 in cold temperatures and 12 in warm. Then the researchers placed the lizards in a plastic container with two exits, one of which was blocked by see-through Plexiglass. The researchers then frightened the lizard by touching their tails. Those incubated in warmer temperatures learned quicker than the others to avoid the exit blocked by Plexiglass. \"Climate change might not be so bad for these guys,\" Joshua Amiel, lead author, said in a press release. However, 2010 study in Science estimated that 20 percent of the world\'s lizard species could go extinct due directly to climate change impacts. The massive study looked at declines in 34 different lizard groups over five continents. The study found that hot days meant lizards spent more time in the shade and less time foraging, this was particularly bad news for breeding. \"The heat doesn\'t kill them, they just don\'t reproduce,\" co-author Jack Sites, a biology professor at Brigham Young University. \"It doesn\'t take too much of that and the population starts to crash.\" People don\'t often think of lizards as \'smart.\' But recent research has shown researchers that lizards may be smarter than expected perhaps even equal to birds. A study last year, also in Biology Letters, found that Puerto Rican anole, a type of lizard, can match birds in intelligence tests. The lizards were capable of solving a problem they\'ve never encountered before, remembering the solution in future trials, and even changing techniques when presented with new challenges.
