Frog Fathers Leave Their Tadpoles In Cannibal-infested Pools
2014-01-22 10:33:10

Springer Male dyeing poison frogs make seemingly strange parental decisions in depositing tadpoles in not-so-safe havens Given a choice, male dyeing poison frogs snub empty pools in favor of ones in which their tiny tadpoles have to metamorphose into frogs in the company of larger, carnivorous ones of the same species. The frog fathers only choose to deposit their developing young in unoccupied pools when others are already filled with tadpoles of a similar size as their own. These are...

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...

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...

Cosmetic Chemical Hinders Brain Development In Tadpoles

A new study finds that low concentrations of the chemical methylisothiazolinone has subtle but measurable negative effects on the neural development of tadpoles. The chemical is found in some cosmetics, although the study does not provide any evidence that cosmetics are unsafe for humans. Scientists, health officials, and manufacturers already know that a chemical preservative found in some products, including cosmetics, is harmful to people and animals in high concentrations, but a new...

Zoologists of the University Jena clarify the role of the gene FOXN3 for the development of the clawed frog "Don't be a frog!" people say in jest when someone hesitates instead of acting straight away. However to be called a frog should actually be a reason to strengthen one's self-confidence. After all frogs are real winners "“ at least from the point of view of evolutionary biology: Nearly 6.000 species are known today. "In terms of numbers frogs are superior to all the other...

Scientists searching for frogs thought to be extinct have instead discovered three new species in Colombia, including two toads and a poisonous rocket frog. All three of the new species are tiny, and are primarily active in daytime "“ a highly uncharacteristic trait for amphibians. Although the conservation scientists failed to re-discover the intended target of the Colombian search, the Mesopotamia beaked toad, they were overjoyed to discover the three new species. "After spending...

Frogs can smell predators when they are still embryos, scientists announced recently. Researchers in the US and Canada discovered that woodfrog embryos could sense any "level of threat" created by salamanders, their enemies. Embryos placed in water full of the odor of salamanders and the smell of hurt tadpoles memorized the predator's scent as a threat. Maud Ferarri, biologist from the University of California, Davis, finds that this kind of learning had been tested in fish, amphibians and...

Scientists say the four-day testing period the U.S. Environmental Protection Agency uses to determine safe levels of pesticide exposure is too short. The University of Pittsburgh researchers said they found the highly toxic pesticide endosulfan -- a neurotoxin banned in several nations, but still used extensively in U.S. agriculture -- can exhibit a lag effect with the fallout from exposure not occurring until after direct contact has ended. The team that included lead author Devin Jones,...

Indirana Semipalmata
2013-07-16 14:01:42

Indirana semipalmata is a species of frog native to the Western Ghats region of southern India. They are frogs of small size, reaching lengths of about 1.4 inches from snout to vent. The species breeds during the monsoons. They lay their eggs on moist rocks and tree bark. Their tadpoles are terrestrial; they hatch, feed, and undergo metamorphosis without ever entering any standing bodies of water. The snout is rounded with moderate canthal ridges. The space between the eyes is around the...

The Smooth Newt (Lissotriton vulgaris), also known as the Common Newt, is the most common newt species in the Triturus genus of amphibians. It is found throughout Europe except the far north, areas of Southern France, and the Iberian peninsula. In Europe, newts are protected and it is illegal to sell, trade, kill or destroy them. While the smooth newt is not endangered, there is insufficient data to make an assessment for two of the subspecies. In the British Isles it is only illegal to sell...
