African stink ants (Paltothyreus tarsatus) really don’t like to be disturbed. They live in colonies of several hundred to thousands, and the 2.5-centimeter-long insects vigorously defend their nests, ...

The African clawed frog is the world’s most widely distributed amphibian. It can be found lurking in ponds on four continents apart from Africa. There is even a population of albino African clawed ...

Researchers at McMaster University have uncovered unexpected diversity in the genetic processes that determine the sex of the African clawed frog, a significant discovery in what was already one of ...

A frog once widely imported and bred by hospitals because it lays eggs when injected with a pregnant woman's urine may have brought a deadly amphibian infection to the United States. African clawed ...

Canadian scientists discovered six new African clawed frog species under the genus Xenopus, increasing the number of identified species by 30 percent. The discovery provides new opportunities for ...

Like most African clawed frogs, researchers found all are 'polyploid', meaning their DNA doubled during evolution, giving them a redundant copy of every gene. Genome duplication occurred several times ...

ISSAQUAH, Wash. — An invasive species is consuming and competing with native species in western Washington, including salmon. Scientists have spotted African clawed frogs in Issaquah, Lacey and ...

GAINESVILLE, Fla., May 6 (UPI) --A deadly fungus has wiped out entire species in Australia, Panama and Madagascar. Now, it's threatening frogs in Africa. According to a new study published in the ...

Millions of years ago, one species of frog diverged into two species. Millions of years later, the two frogs became one again, but with a few extra chromosomes due to whole genome duplication. Such is ...
