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...

Predators Drive Evolution Of Poison Dart Frogs' Skin Patterns
2011-11-22 04:10:01

Natural selection has played a role in the development of the many skins patterns of the tiny Ranitomeya imitator poison dart frog, according to a study that will be published in an upcoming edition of American Naturalist by University of Montreal biologist Mathieu Chouteau. The researcher's methodology was rather unusual: on three occasions over three days, at two different sites, Chouteau investigated the number of attacks that had been made on fake frogs, by counting how many times that...

Springy Tendons Key To Frogs' Amazing Leaps
2011-11-17 04:08:54

The secret to frogs´ superlative jumping lies in their tendons. Researchers at Brown University, filming frogs jumping at 500 frames per second with special X-ray technology, show that the frog's tendon stretches as it readies its leap and then recoils, much like a spring, when the frog jumps. The finding could explain how other animals are exceptional leapers. Results appear in Biology Letters. Some species of frogs and many other animals are able to jump far beyond what appear to be...
