An invasive plant may have saved an iconic Australian lizard species from death at the hands of toxic cane toads, according to research published in the March issue of The American Naturalist. It's an interesting case of one invasive species preparing local predators for the arrival of another, says Richard Shine, a biologist at the University of Sydney who led the research. Cane toads were introduced in Australia in the 1930s to control beetles that destroy sugar cane crops, but the toads...

Listen to biophony, geophony, anthrophony: the 'music' of Planet Earth Geophony. Biophony. Anthrophony. Unfamiliar words. But they shouldn't be. We're surrounded by them morning, noon and night, say ecologist Bryan Pijanowski of Purdue University and colleagues. The evening "singing" of frogs. Burbling brooks, breaking waves and the whistling wind. Planes, trains and automobiles. Biophony is the music created by organisms like frogs and birds; geophony, the composition of...

Scientists Discover 40 New Species
2012-01-25 14:27:15

A team of scientists have discovered over 40 new species in southwestern Suriname during a Rapid Assessment Program (RAP) survey. The scientists found 40 previously unknown species of fish, a frog, katydids, damselflies, water beetles and scarab beetles. Trond Larsen, director of Conservation International's RAP, wrote that the team was able to develop important strategies for sustainable management of natural resources. "It´s imperative that we understand which species exist...

This Tiny Frog Is The World's Smallest Vertebrate
2012-01-12 10:40:21

A frog species -- discovered in Papua New Guinea by US researchers -- that is less than half the size of a US dime, has been named the world´s smallest vertebrate species, smaller than a fish that won the honor in 2006. The frog, Paedophryne amauensis, which is about 7mm (0.27 in) long, was given the distinction of world´s smallest animal with a spine in Wednesday´s PLoS One journal. The researchers, led by Chris Austin of Louisiana State University made the discovery, along...

World's Smallest Frogs Found In New Guinea
2011-12-12 08:29:12

Field work by researcher Fred Kraus from Bishop Museum, Honolulu has found the world's smallest frogs in southeastern New Guinea. This also makes them the world's smallest tetrapods (non-fish vertebrates). The frogs belong to the genus Paedophryne, all of whose species are extremely small, with adults of the two new species - named Paedophryne dekot and Paedophryne verrucosa - only 8-9 mm in length. The study was published in the open access journal ZooKeys. Previous research had led to...

Changes In Bioelectric Signals Cause Tadpoles To Grow Eyes In Back, Tail
2011-12-09 03:55:59

For the first time, scientists have altered natural bioelectrical communication among cells to directly specify the type of new organ to be created at a particular location within a vertebrate organism. Using genetic manipulation of membrane voltage in Xenopus (frog) embryos, biologists at Tufts University's School of Arts and Sciences were able to cause tadpoles to grow eyes outside of the head area. The researchers achieved most surprising results when they manipulated membrane voltage...

Some of the nastiest smelling creatures on Earth have skin that produces the greatest known variety of anti-bacterial substances that hold promise for becoming new weapons in the battle against antibiotic-resistant infections, scientists are reporting. Their research on amphibians so smelly (like rotten fish, for instance) that scientists term them "odorous frogs" appears in ACS' Journal of Proteome Research. Yun Zhang, Wen-Hui Lee and Xinwang Yang explain that scientists long have...

Herbicide Spurs Reproductive Problems In Many Animals
2011-11-29 04:19:57

An international team of researchers has reviewed the evidence linking exposure to atrazine — an herbicide widely used in the U.S. and more than 60 other nations — to reproductive problems in animals. The team found consistent patterns of reproductive dysfunction in amphibians, fish, reptiles and mammals exposed to the chemical. Atrazine is the second-most widely used herbicide in the U.S. More than 75 million pounds of it are applied to corn and other crops, and it is the most...
