2013-05-20 13:16:57

BioMed Central What lures a lady frog to her lover? Good looks, the sound of his voice, the size of his pad or none of the above? After weighing up their options, female strawberry poison frogs (Oophaga pumilio) bag the closest crooner they can, finds research in BioMed Central's open access journal Frontiers of Zoology. This seemingly short-sighted strategy turns out to be the optimal mate choice strategy for these colorful frogs. Males of the species congregate in the Costa Rican rain...

Climate Change Impacts On Amphibians Studied By USGS Experts
2013-05-19 06:22:41

[ Watch the Video: What is Climate Change ] redOrbit Staff & Wire Reports - Your Universe Online A US Geological Survey (USGS) effort to monitor the impact of climate change on amphibians living in the ponds and swamps of the southeastern United States has discovered that changes in rainfall patterns can cause short-term declines in mole salamanders, the agency reported on Friday. As part of their research, the USGS´s Amphibian Research and Monitoring Initiative (ARMI)...

Cannibalistic Tadpoles Key To Understanding Digestive Evolution
2013-05-08 16:01:09

North Carolina State University A carnivorous, cannibalistic tadpole may play a role in understanding the evolution and development of digestive organs, according to research from North Carolina State University. These findings may also shed light on universal rules of organ development that could lead to better diagnosis and prevention of intestinal birth defects. NC State developmental biologist Nanette Nascone-Yoder, graduate student Stephanie Bloom and postdoc Cris Ledon-Rettig...

Underground Adventures Of A Mediterranean Frog
2013-04-30 10:45:25

Pensoft Publishers Do frogs live underground? The answer is yes, some amphibians, such as salamanders and frogs have been often reported to dwell in subterranean habitats, some of them completely adjusted to the life in darkness, and others just spending a phase of their lifecycle in an underground shelter. Up until 2010, however, no one suspected that the Mediterranean anuran frog Rana iberica - commonly known as Iberian brown frog and usually found in streams - also participates in...

Lazarus Project Attempts To Resurrect Extinct Frog
2013-03-16 08:21:22

April Flowers for redOrbit.com — Your Universe Online A team of scientists, led by the University of New South Wales (UNSW), has used sophisticated cloning techniques to revive and reactivate the genome of an extinct Australian frog by implanting a "dead" cell nucleus into a fresh egg from another frog species. Rheobatrachus silus was a bizarre gastric-brooding frog that swallowed its eggs, brooded its young in its stomach and gave birth through its mouth. The frog species became...

American bullfrogs are native to eastern North America but have been transported by people to many other parts of the globe, and other parts of North America, where they have readily established populations and become an invasive alien menace to native ecosystems. In the largest study of its kind to date, the stomach contents of over 5,000 invasive alien American bullfrogs from 60 lakes and ponds on southern Vancouver Island were examined to identify the native and exotic animals that they...

Brett Smith for redOrbit.com - Your Universe Online According to a new report from the Centers for Disease Control and Prevention (CDC), an outbreak of Salmonella infections from 2008 to 2011 was caused by small, aquatic pet frogs. "This was the first Salmonella outbreak associated with aquatic frogs, and in this case the frogs are often marketed as good pets for kids," lead author Shauna Mettee Zarecki, a public health advisor“¯with the CDC in Atlanta, told Reuters.

Tadpoles Able To See With Eyes Transplanted Onto Their Back
2013-02-28 10:29:13

Brett Smith for redOrbit.com - Your Universe Online In a study that could have implications for organ transplant procedures, two scientists from Tufts University found that eyes placed on the backs of tadpoles were still capable of vision despite having no direct neural connection to the brain. "A primary goal in medicine is to one day be able to restore the function of damaged or missing sensory structures through the use of biological or artificial replacement components,” said...

Amphibian Biodiversity Makes Entire Ecosystem Healthier
2013-02-14 12:24:37

April Flowers for redOrbit.com - Your Universe Online A new study from the University of Colorado, Boulder shows that the richer the biodiversity of amphibian species living in a pond, the more protection that ecosystem has against parasitic infections. The finding of the study support the broader theory that greater biodiversity in large-scale ecosystems such as forests or grasslands may also provide greater protection against diseases, including those that attack humans. A larger...
