There's a crisis among the world's amphibians"”about 40 percent of amphibian species have dwindled in numbers in just three decades. Now, museum jars stuffed full of amphibians may help scientists decide whether this wave of extinctions was caused by a fungal infection. DNA swabbed from the preservative-soaked skins of salamanders, frogs and toads"”collected from some of Central America's best-known extinction hotspots"” revealed a startling but clear pattern. Salamanders in...

Researchers have discovered that a green algae invades tiny developing salamander embryos. The team from Dalhousie University in Halifax, Canada was the first to document a case of a plant living in partnership with a vertebrate. The researchers think that the salamanders might inherit the algae from their parents. The study is published in Proceedings of the National Academy of Sciences. It was already known that green algae lived inside the eggs of the spotted salamander species, which...

A species of algae long known to associate with spotted salamanders has been discovered to live inside the cells of developing embryos, say scientists from the U.S. and Canada, who report their findings in this week's Proceedings of the National Academy of Sciences.This is the first known example of a eukaryotic algae living stably inside the cells of any vertebrate."It raises the possibility that more animal/algae symbioses exist that we are not aware of," said Indiana University Bloomington...

Researchers reported on Tuesday that climate change is affecting the breeding cycles of toads and salamanders. They documented that two species were breeding later in the autumn than in years past, and two others were breeding earlier in the winter. Their study adds to a growing body of evidence that climate change is affecting animals. Other studies have found that some birds in North America and Europe are moving northwards as temperatures rise. Brian Todd of the University of...

Another option may be on the horizon for patients who lose limbs due to war, accident, or disease. Instead of using artificial legs or arms, patients actually may regrow their own missing limbs. An article in the current issue of Chemical & Engineering News (C&EN), ACS' weekly newsmagazine, focuses on research efforts to turn the long-standing dream of human limb regeneration into reality. C&EN Senior Editor Sophie Rovner notes that salamanders, flatworms, and certain other...

In nature, ultraviolet radiation from sunlight is not the amphibian killer scientists once suspected. Naturally occurring murky water and females who choose to lay their eggs in the shade keep embryos of one of the nation's most UV-sensitive amphibian species out of harm's way most of the time, new research shows. Less than 2 percent of the embryos of the long-toed salamander received lethal doses of UV across 22 breeding sites across nearly 8 square miles (20 square kilometers) in Washington...

MU researchers find clear-cutting is harmful to the terrestrial stage of amphibians Frogs are croaking in clear-cut forests, but not exactly in their traditional manner. University of Missouri researchers found that removing all of the trees from a section of the forest had a negative effect on amphibians during their later life cycles, but had some positive effects during amphibians' aquatic larva stages at the beginning of their lives. To lessen the negative effects during the later life...

California tiger salamanders face a threat from a hybrid relative as well as from over development and pollution, researchers said. Very little development threatened the amphibians 60 years ago when commercial bait sellers in California imported barred tiger salamanders from Texas, a biologist from the University of California Davis told the San Francisco Chronicle. Maureen Ryan of the Center for Population Biology at UC Davis said the larvae of the new salamanders was popular bait, but the...

The salamander is known for its regeneration, as it can replace lost limbs, lungs, its spinal cord, and even parts of its brain that it has lost. New research says that the unique ability might one day be duplicated by scientists to use in humans. Until now, biologists have credited the regeneration to the salamander's "pluripotent" cells, which surge to the area of amputation, or a blastema, and act like human stem cells in their versatility. Pluripotent cells are persuaded by signals into...

The California giant salamander (Dicamptodon ensatus) is a member of the Dicamptodontidae family. The species is native only to northern California. The California giant salamander inhabits moist, coastal forests or streams, lakes and ponds. Some of the species may remain gilled aquatic creatures, while others transform and become terrestrial land creatures. The California giant is nocturnal and most of its life is spent hiding and burrowing. Typically, the California giant salamander...

The Axolotl, Ambystoma mexicanum
2014-02-03 08:59:54

Axolotl (Ambystoma mexicanum) may also be referred to as the Mexican salamander or the Mexican walking fish. The Axolotl is a member of the Ambystomatidae family and although its common name may suggest it is a fish, it is an amphibian. Axolotl are found exclusively in Mexico. The species situates, near Mexico City, on the bottom of Xochimilco’s lakes. Unlike most salamanders, Axolotl keep its larval features throughout its entire life and very rarely ever emerge from water. A condition...
