Study Shows Impact Of Polyandry On Reproductive Success In Fire Salamanders
2013-12-02 16:11:27

University of Bielefeld Researchers at Bielefeld University and the Technische Universität Braunschweig are the first to confirm the benefit of multiple paternities for a vertebrate under completely natural conditions. Together with their team, Dr. Barbara Caspers and Dr. Sebastian Steinfartz have shown that female fire salamanders mate with several males under natural conditions (so-called polyandry). This grants them fitness-relevant benefits by increasing their number of offspring. The...

Scientists at Karolinska Institutet in Sweden have discovered that two separate species of salamander differ in the way their muscles grow back in lost body parts. Their findings on the species-specific solutions, published in the scientific periodical Cell Stem Cell, demonstrate there is more than one mechanism of tissue regeneration. To carry out their study, the scientists labelled different cell types in two species of salamander in order to ascertain what kinds of cell give rise to...

The journal Herpetologica presents a study in which Barton Springs Salamanders were exposed to three different species of fish predators—the Western Mosquitofish, Redbreasted Sunfish, and Largemouth Bass—and a blank water control. The current study used captive-bred salamanders that had never been exposed to the predators before and could not have a learned response. (PRWEB) September 11, 2013 How a species reacts to potential predators plays a role in how conservationists might...

Salamanders Threatened By Deadly Skin-eating Fungus
2013-09-03 07:59:33

Imperial College London A new species of fungus that eats amphibians' skin has ravaged the fire salamander population in the Netherlands, bringing it close to regional extinction. Fire salamanders, recognizable by their distinctive yellow and black skin patterns, have been found dead in the country's forests since 2010. The population has fallen to around 10 individuals, less than four per cent of its original level, but what has been killing them has been a mystery until now....

The Land Invasion Race: The Evolution Of Fins To Limbs
2013-07-07 19:51:23

Society for Experimental Biology Why did animals with limbs win the race to invade land over those with fins? A new study comparing the forces acting on fins of mudskipper fish and on the forelimbs of tiger salamanders can now be used to analyze early fossils that spanned the water-to-land transition in tetrapod evolution, and further understand their capability to move on land. Research conducted by Sandy Kawano and Richard Blob at Clemson University compared terrestrial locomotion in...

A study in the journal Herpetologica clarifies confusion about the role of the most abundant vertebrate predator in the forests of eastern North America. Eastern Red-backed Salamanders might prevent any particular prey type from becoming very abundant or very scarce by preying more heavily on some species in the spring, but other species in the fall, which would promote coexistence of decomposer organisms, maintain biodiversity, and stabilize rates of decomposition. (PRWEB) June 04, 2013...

United States Amphibian Populations Rapidly Declining
2013-05-25 05:57:30

redOrbit Staff & Wire Reports - Your Universe Online The number of frogs, toads and salamanders in the US could be falling at an even more severe and widespread rate than previously believed, and even amphibian populations thought to be stable are actually on the decline, according to new research for the US Geological Survey (USGS). The study, which was published earlier this week in the journal PLOS ONE, is believed to be the first-ever estimate of how quickly amphibians across...

Macrophages Key In Salamander Regeneration
2013-05-21 15:06:03

Brett Smith for redOrbit.com - Your Universe Online For years, scientists have considered salamanders the ℠Holy Grail´ of biological regeneration. Now, a new study in the Proceedings of the National Academy of Sciences has revealed an exciting step forward in the quest to adapt this ability for medical use in humans. Based on experiments with the tiny amphibians, researchers from the Australian Regenerative Medicine Institute at Monash University have found that elements of a...

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)...

Ichthyostega_BW
2012-05-24 19:20:53

Lee Rannals for RedOrbit.com Scientists say that the 360-million-year-old animal that was first to have moved around on land did not do so using four legs. Images have shown that Ichthyostega walked on land similar to how a salamander walks around today, but 3D computer models have led scientists to disagree. According to a study published in the journal Nature, Ichthyostega would have actually transported from water using its front limbs as crutches. The animal lived during the...

Hellbender Salamander, Cryptoranchus alleganiensis
2014-05-26 09:58:06

The hellbender salamander (Cryptoranchus alleganiensis), also known as the hellbender, is a species of giant salamander that can be found in eastern areas of North America. Its range includes the states of Ohio, Maryland, Virginia, Tennessee, Alabama, Arkansas, and some areas of Kansas and Oklahoma. This species is the sole member of its genus, Cryptobranchus, and is one of three living giant salamanders. The origin of the name hellbender is unknown and the species is locally known by many...

Jefferson Salamander, Ambystoma jeffersonianum

The Jefferson salamander (Ambystoma jeffersonianum) is a species of mole salamander that can be found in northeastern areas of the United States, southwestern areas of Quebec, and central and southern areas of Ontario. This species prefers to reside in deciduous forests. It was named after Jefferson College, which is located in Pennsylvania. This species reaches an average body length between 4.3 inches and 7 inches and can be black, gray, or brown in color with lighter coloring on its front...

California slender salamander, Batrachoseps attenuatus
2014-02-04 09:23:14

The California slender salamander (Batrachoseps attenuatus) is a member of the Plethodontidae family of salamander species. The species is native to California and southwest Oregon. The California slender salamander ranges from central California, north along the coast and ranges into Oregon and in the foothills of the Sierra Nevada mountains. The California slender salamander grows to lengths between 3 to 5.5 inches. As its name implies, a slim body with short limbs gives this salamander...

California giant salamander, Dicamptodon ensatus
2014-02-04 09:07:49

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...
