Little is known about Africa's elusive aardvarks, but new research says they are vulnerable to climate change like many other species. The aardvarks' body temperatures plummeted during the night because they were not getting enough energy from diminished food sources, said physiology professor Andrea Fuller. They could have fewer refuges available if aardvark populations shrink because of rising temperatures, they said. Estimating aardvark populations is guesswork, Fuller said. "Very little is known about them because people hardly ever see them," she said.
