Recent discoveries of a Lilliputian lizard and elfin amphibian, fascinating in their own right, highlight one of the most enduring questions in biology: what controls the evolution of body size? They also provide a rare bright spot amid the relentless reports of endangered and disappearing amphibian and reptile species around the world.
The USGS National Wildlife Health Center investigates animal die-offs and threats to endangered species through on-site investigation and necropsies–animal autopsy–at its headquarters in Madison, Wisconsin.
The newts are on the move again. Each fall, after the rains start, the newts of Berkeley’s Tilden Park start migrating from the woods to waters of Wildcat Creek, where they mate and lay their eggs. South Park Drive, popular with cyclists and Sunday drivers, crosses their migratory path. Each year from November 1 to April 1 the road is closed to cars, to prevent the newts from getting squished. (How did the newt cross the road? Not by being run over, that’s for sure.)

But once year, the newts make an epic migration (at least for them) to nearby ponds for mating season. It's incredible to see dozens of […]
