Algal pool site from Yellowstone. The location photographed is marked by an arrow in the hyperspectral map in which this and other predicted algal pools appear in red.

And unless you were willing to walk on both sides of the canyon, hundreds of meters away from the stream, you wouldn't have known those sites were there," Peterson says. Predictions of algal ponds proved slightly less accurate. Of the 16 algal sites predicted by the imagery, four had no algae, though one of those four turned out to be a frog habitat after all. But not every algal pool is a frog breeding site. Peterson says, "We've been able to play with the imagery and can get rid of those over-predictions now that we know a little more about it.
So the results of the hyperspectral analysis are really promising," says Peterson. Each area surveyed by the hyperspectral mapper was 20 to 30 miles approximately 30 to 50 kilometers long, covering terrain that can be difficult to traverse on foot.

In addition to locating new breeding sites, amphibian research in the Yellowstone area has revealed some unwelcome news. Debra Patla, one of Peterson's research associates, has collected toads in Jackson Hole, Wyoming that have tested positive for the Chytrid fungus.
This is the first report of the disease in the northwest Wyoming. Whether this discovery signals an impending wave of toad population losses in Yellowstone and the Teton Range similar to those in Colorado remains unknown. Cautious about spreading the chytrid fungus between populations, Peterson and his research assistants wash their boots and equipment in bleach solution before visiting new sites, but Peterson points out that introduced species also present a problem.
People have stocked nearly all the deep high mountain lakes with trout. Yet Peterson, along with many other biologists, believes the frogs' biggest problem may be loss of habitat. These amphibian populations get broken up and isolated from each other, and then they're more likely to go extinct.
Ancestors of modern frogs evolved during the Jurassic, and this group of amphibians has inhabited Earth for million years, surviving the K-T extinction that wiped out the dinosaurs. Frogs' sudden failure to thrive suggests a significant ecosystem change. They don't all get together in a pool to breed. They don't call. You can't look into a pool and see their larvae.
Amphibians are probably more susceptible to changes in the environment, but equally important is the fact that you can see what's happening to them. Amphibians are often a good indicator of ecosystem health. Each species is different and requires specialized care, and a different diet. With over 7, species, it is nearly impossible to lump all animals into one behavioral category. Some species spend their days hiding from predators, and search for food at night.
Other species are more active during the day, and rest overnight. Social behavior also varies from species to species. Some species display solitary behavior, and live alone. Others spend most of their time alone, but congregate in large numbers seasonally. While some species deviate from this behavior, the vast majority of Frogs breed by producing eggs.
Those eggs hatch into tadpoles, which metamorphose into Frogs. Most species lay their eggs in water. The tadpoles then spend all their time in the water until they grow their legs, and develop their lungs! Once tadpoles grow legs, their tails slowly disappear.
When they reach adulthood, they look like a smaller version of their parents. At hatching, most tadpoles are fully independent. However, some species do protect their eggs, or their tadpoles. Animals Network. Chordata Amphibia Anura. Red Angus. Paint Horse. Black Sole. Expert Recommendations.
