Studies on
other amphibian species have revealed strong effects of this type, and Jayna has discovered that the same thing happens with cane toads.
A Yosemite frog that lost 93 per cent of its habitat and was in decline for over a century has started recovering, raising hope for the survival
of other amphibians, too
Unusually for an infectious disease even at very low rates of infection, and in the absence of the dramatic die - offs witnessed
in other amphibian populations impacted by this disease, infected populations of Darwin's frogs are destined for extinction.»
There are only two known living specimens, both refugees from a place in Panama devastated — like so
many other amphibian habitats — by the spreading chytrid fungus.

Symbiotic bacteria may help frogs and
other amphibians ward off the chytrid fungus plague wiping out populations worldwide
Future research will focus on those species to learn how they are able to escape Bd's harmful effects and see how that knowledge can be used to
save other amphibians.
Several species of frogs, salamanders, toads and
other amphibians around the world have gone extinct or are disappearing («Decline and fall of the amphibians», New Scientist, 27 June 1992).
Frogs and
other amphibians gauge ambient oxygen concentrations through their skin, but nobody had ever checked to see if mammals had the same ability.
The second change involved in the transition to frogs and toads
from other amphibians was in the sacral ribs, broad bones attached to a vertebra which in most land - living vertebrates fit below and inside the pelvis to hold it fixed relative to the backbone.
An older fossil, Triadobatrachus massinoti, which lived in Madagascar 235 million years ago, seems to link frogs and toads
with other amphibians.
Frogs and
other amphibians face the serious threat of extinction, largely due to their extreme sensitivity to their environment and, particularly, to pollution.
In the years following the Persian Gulf War, there were news reports of frogs and
other amphibians inexplicably vanishing, the rainforest being destroyed, and an ozone hole developing over the South Pole.
Other amphibian species such as the alpine newt react less sensitively to Batrachochytrium salamandrivorans; what is lucky for the alpine newt, however, involves an additional risk: «More robust species may act as a reservoir,» Benedikt Schmidt explains.
Nevertheless, Carroll says that even earlier fossils will have to be discovered to determine exactly when the ancestral frogs split from the lineage
of other amphibians.
«The goal is for scientists to augment naturally occurring bacteria» so that these helpful symbiants can spread to even more frogs and
other amphibians, Harris says.
Frogs and
other amphibians have hit hard times in the past decade or two: Their populations are down worldwide.
Right now, at least 2,000 frogs, salamanders and
other amphibians are in danger of going extinct, according to a survey by biologists David Wake and Vance Vredenburg, writing in the Proceedings of the National Academy of Sciences USA.
There's a glimmer of hope for frogs and
other amphibians that are being wiped out by a lethal disease.
They are cold - weather frogs with a range that extends farther north than
other amphibians.
They are cold - weather frogs with a range that extends further north than
other amphibians.
Frogs and
other amphibians, meanwhile, are battling a killer fungus of their own.
Other amphibian species also will become vulnerable or threatened, lacking a way to reach a more suitable habitat.
Frogs, salamanders, and
other amphibians aren't known as faithful lovers.
Seeing the salamander in the wild is rare, due to their nocturnal activity and dwindling populations, but an on - site museum, located at the park's entrance, has giant salamanders as well as an international variety of
other amphibians.
Frogs, for example, are a critical part of the forest ecosystem, living with salamanders and
other amphibians in vernal pools.
In the United States, no agency directly regulates imports of salamanders or
other amphibians.
