Although the green toad (Bufo viridis) can today be found all over Central Europe, Asia, Africa, and even on the Balearic Islands, it became extinct in the Iberian Peninsula at the end of the Early Pleistocene (1.1 million years ago). This has been demonstrated by an international research study, with Spanish participation, which has discovered the first green frog fossil in Murcia. Analysis of fossils found in the Cueva Victoria deposit in Cartagena (Murcia), has for the first time confirmed...

Scientists hope the toxic cane toad that has rampaged around northeastern Australia may at last be stopped. The cane toad, which is a native of Central America, was introduced to Australia in 1935 to kill beetles devastating sugar-cane crops, only to become a pest in its own right. However, a new investigation says the toad has an Achilles' heel. The imported anuran desperately needs access to nearby standing water in order to survive, unlike indigenous amphibians that have adapted to arid...

Frogs appear to be very sensitive to progestogens, a kind of pharmaceutical that is released into the environment. Female tadpoles that swim in water containing a specific progestogen, levonorgestrel, are subject to abnormal ovarian and oviduct development, resulting in adult sterility. This is shown by a new study conducted at Uppsala University and published today in the scientific journal Aquatic Toxicology. Many of the medicines that people consume are released into the environment via...

Amphibian experts have long wrangled over the origins of the Greenhouse frog (Eleutherodactylus planirostris) and the Cuban treefrog (Osteopilus septentrionalis). The two species of invasive frog which are hopping their way through Florida probably got to the state by hitching a ride on floating debris from Cuba, according to a study published on Wednesday, reports AFP. The two species are widespread across the Caribbean, but were first spotted in the Florida Keys -- the island chain that...
