Plans to dig a 78-million-ton gravel mine in the Santa Clarita Valley would not jeopardize the survival of the endangered arroyo toad, federal officials said Thursday. Biologists for the U.S. Fish and Wildlife Service did not find any adult toads on the property surrounding the proposed Soledad Canyon mine, where arroyo toad tadpoles were discovered last spring in pools along the Santa Clara River.

Trout planted in Yosemite National Park's lakes and streams over the decades may partly explain declines in frog and toad populations, scientists say. Results of a 1992 survey published in the current issue of Conservation Biology indicate that there were fewer frogs and toads of most types than in 1915. Researchers said people began stocking Sierra streams in the 1920s with trout, which eat frog eggs, tadpoles and adult frogs.

AS they seek to document and demystify one of life's great thrills, scientists have run across some real head-scratchers. How, for example, can they explain the fact that some men and women who are paralyzed and numb below the waist are able to have orgasms? How to explain the "orgasmic auras" that can descend at the onset of epileptic seizures -- sensations so pleasurable they prompt some patients to refuse antiseizure medication? And how on Earth to explain the case of the amputee who felt his orgasms centered in that missing foot?

[ RANA MUSCOSA ] Sleeping under lakes lidded with several feet of ice and snow, the 2- to 3-inch-long yellow-legged frog of the High Sierra awaits not only the spring thaw but also critical decisions that will determine its fate. Once abundant in the Sierra Nevada and in mountain ranges circling the Los Angeles Basin, these hardy amphibians number fewer than an estimated 100 individuals in all of Southern California plus a remote area of Yosemite and Kings Canyon-Sequoia national parks.
Rain? Sleet? Gloom of night? None of them really compare with those interminable post office lines this time of year. But before you take it out on that clerk behind the counter, you should know that he has at his disposal an arcane reserve of knowledge that could enable him to declare your package "unmailable." It's called the Domestic Mail Manual (DMM), and you don't want to make him get out this book.

Nearly 400 children participated in the Saddleback Valley YMCA's fifth annual Backyard Swim Program. Children 6 months to 3 years old participated in the recently completed Waterbabies sessions (also called the Mommy and Me programs), which are designed to help youngsters become acquainted with the water and learn fundamental aquatic skills. The Tadpoles division, a beginning swimmer course, accepted children 3 to 5 years old.

The rare mountain yellow-legged frog recovers nicely in lakes once trout are expelled, according to a new study. The frogs swarmed the Sierra a century ago, but their numbers have plummeted since the 1980s and they are endangered in Southern California. UC Berkeley biologist Vance T. Vredenburg monitored 21 mountain lakes for eight years.

Biologists are trying to decipher a baffling quirk of nature in a giant frog pond where hundreds of amphibians are developing more than their usual complement of legs--some as many as eight. For years scientists have known that frogs and salamanders have the genetic ability to generate new limbs when any of the original ones are severed.

It's a lucky day for amphibian enthusiasts at Glen Austin wetlands: The giant bullfrogs of southern Africa are having sex. The mating ritual occurs just one day a year, after the first downpour of the Southern Hemisphere summer. The shallows of the wetlands north of Johannesburg become a splashing commotion as bullfrogs attack and toss each other about like pint-sized wrestling stars. The giant bullfrog is like Kermit on steroids. When it lunges ? and South African frog expert Vincent Carruthers has seen it attack horses ?
