Snakes Evolve Along Similar Path Of Poison Resistance Say Biologists
2012-03-06 04:57:40

Utah State University biologists have long studied varied species of North American garter snakes that have evolved an amazing resistance to a deadly neurotoxin found in innocuous-looking newts, a favorite food of the snakes. The researchers have now discovered that snakes of different types in Central and South America and Asia have evolved the same resistance in a strikingly similar way. The findings, by USU alum Chris Feldman, PhD´08, now a faculty member at the University of...

Amphibians In Regions With Diversity Are Most At Risk
2011-11-17 12:55:16

According to new research, tropical regions with the richest diversity are most at risk of losing frogs, toads, newts and salamanders. Scientists predict the future for these amphibians is even more bleak than conservationists had thought. They predict that areas with the highest diversity of amphibian species will be under the most intense threat in the future.  About half of amphibian species are in decline, while a third that are already threatened with extinction. The...

Study has implications for reprogramming human cardiac myocytes to replace damaged heart muscle Stem cell researchers at UCLA have uncovered for the first time why adult human cardiac myocytes have lost their ability to proliferate, perhaps explaining why the human heart has little regenerative capacity. The study, done in cell lines and mice, may lead to methods of reprogramming a patient's own cardiac myocytes within the heart itself to create new muscle to repair damage, said Dr. Robb...

Move over, newts and salamanders. The mouse may join you as the only animal that can re-grow their own severed limbs. Researchers are reporting that a simple chemical cocktail can coax mouse muscle fibers to become the kinds of cells found in the first stages of a regenerating limb. Their study, the first demonstration that mammal muscle can be turned into the biological raw material for a new limb, appears in the journal ACS Chemical Biology. Darren R. Williams and Da-Woon Jung say their...

Amphibians"”frogs, toads, salamanders, and newts"”are disappearing worldwide, but the stream salamanders of the Appalachian Mountains appear to be stable. This region is home to the largest diversity of salamanders in the world (more than 70 species reside here), and scientists want to understand what contributes to the stability of these salamander populations. In research published in the March 29, 2010 issue of the Proceedings of the National Academy of Sciences, Dr. Evan Grant...

Doha, Qatar "“ A little-known Iranian salamander is poised to become the first example of a species requiring international government protection because of e-commerce "“ a major threat to endangered wildlife that authorities are struggling to address. The Kaiser's spotted newt, found only in Iran, is considered Critically Endangered and is believed to number fewer than 1,000 mature wild individuals. The amphibian is being proposed for an Appendix I listing during a meeting of...

When it comes to mating, timing is everything for amphibians. Researchers have found that the mating activity of amphibians is synchronized by the full Moon. The fascinating fact that frogs, toads and newts across the globe seem to enjoy mating by moonlight has never before been noticed. It appears that in order to make sure that a sufficient number of males and females join up at the same time, they use the lunar cycle to co-ordinate their gatherings. This proves to be an ingenious...

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...

Pyrenean Brook Salamander, Calotriton asper
2013-10-07 15:25:48

The Pyrenean Brook Salamander (Calotriton asper) is a species of salamander belonging to the Salamandridae family. It is located in the Pyrenees of Andorra, France, and Spain. Its natural habitats include temperate forests, intermittent rivers, rivers, freshwater lakes, freshwater marshes, caves, and inland karsts. It is threatened by loss of habitat. This salamander can grow to about 3.6 inches long, half of which is the laterally flattened tail. The females are normally larger than...

Corsican Brook Salamander, Euproctus montanus

The Corsican Brook Salamander (Euproctus montanus), known also as the Corsican Mountain Newt, is a species of salamander belonging to the Salamandridae family. It is native to Corsica, an island in the Mediterranean Sea. It is found mostly in rocky streams, springs, and rivers in forest and maquis and altitudes of over 600 meters. It is smaller than other closely related species, such as the Sardinian Brook Salamander (Euproctus platycephalus) and can reach a length of about 5 inches,...
