and can influence reproduction in amphibians. The results suggest that atrazine which is used a weed killer primarily on corn crops,
could have potentially harmful effects on populations of amphibians, animals that are already experiencing a global decline,
the findings could have implications for humans as well. oeif you have problems in amphibians, you can anticipate problems in other animals,

#New legless amphibian found in India An adult Chikilidae, a new species of legless amphibian known as a caecilian, with eggs and hatchlings.
But this legless amphibian s time in obscurity has ended, thanks to an intrepid team of biologists led by University of Delhi professor Sathyabhama Das Biju.
Over five years of digging through forest beds in the rain, the team has identified an entirely new family of amphibians called chikilidae endemic to the region but with ancient links to Africa.
The chikilidae is a caecilian, the most primitive of three amphibian groups that also include frogs and salamanders.
We hope when the locals see the name, and their language, being used across the world,
#Amphibians are particularly vulnerable, and have declined drastically in recent decades. The same sensitivity to climate and water quality that makes them perfect environmental barometers also puts them at the greatest risk
caecilians and frogs vastly more than any other scientist in India and estimates 30-40 percent of the country s amphibians are yet to be found.
along with co-researchers from London s Natural history Museum and Vrije University in Brussels, brings the number of known caecilian families in the world to 10.
Only 186 of the world s known amphibious species are compared caecilians with more than 6, 000 frog species a third
Even people living in northeast Indians misunderstand the caecilians, and rare sightings can inspire terror and revulsion,
and may help the chikilidae gauge light from dark as in other caecilian species. DNA testing suggests the chikilidae s closest relative is in Africa with the two evolutionary paths splitting some 140 million years ago
which infects frogs and other amphibians by way of their skin — has been implicated in the deaths of hundreds of amphibians in recent years including nearly 75 percent of the mountain yellow-legged frog population in California's Sierra nevada mountains.</

A few escaped carrying with them a fungus Batrachochytrium dendrobatidis that's blamed for a massive die off of native North american frogs and other amphibians.
Amphibians are on the decline worldwide. Besides being at risk of deadly fungal infections frogs salamanders
In a recent report on the sharp decline of the creatures in the United states researchers found that amphibians have been disappearing from their habits at a rate of 3. 7 percent each year.
Agricultural pesticides and fungicides have been detected more than 100 miles (160 kilometers) to the east in the rural Sierra nevada's snow water air and amphibians.
Amphibians everywhere are suffering steep population losses and strange deformities. Earlier studies by the USGS researchers found toxic pesticide concentrations in several frog species living in the national parks. In 2009 and 2010 the scientists resurveyed many of the same sites Smalling said.
and how they interact with the amphibians Smalling said. While scientists agree that pesticides likely contribute to the dramatic decline in amphibians there are many reasons that frogs are disappearing.
The heavyweight is habitat destruction and degradation followed by an infectious disease called chytridiomycosis. In the Sierras introducing trout into mountain lakes also hit frogs hard

And these plant communities support more than 400 species of birds 53 species of reptiles and 28 species of amphibians.
Dated from the mid-Devonian this fossil creature is considered to be the link between the lobe-finned fishes and early amphibians.

Just Like Lizards'Tailssome lizards and amphibians have the ability to regrow severed tails or limbs--in fact the blue-tailed skink abandons its tail intentionally to distract predators.

The new species previously unknown to science include 38 different ants 12 fishes 14 plants eight beetles two spiders one reptile and one amphibian.
Initial studies indicate though that they may possibly have a strong effect on amphibians such as frogs.
however amphibians are increasingly becoming accepted as researchers verify their applicability and usefulness. The woodland salamanders evaluated in Mill Creek were deemed credible due to their conservatism trophic role
Intensive farming is linked also to collapsing populations of wild animals and the endangerment of species such as amphibians.
#Early exposure to insecticides gives amphibians higher tolerance lateramphibians exposed to insecticides early in life--even those not yet hatched--have a higher tolerance to those same insecticides later in life according to a recent University of Pittsburgh study.

The paper Pesticide Tolerance in Amphibians: Induced Tolerance in Susceptible Populations Constitutive Tolerance in Tolerant Populations first appeared online in Evolutionary Applications.
As with other amphibians agrochemicals potentially pose a threat to chorus frogs as exposure to pesticides can decrease their immune system thereby increasing the risk of disease.
