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.

[ 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.

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 sore trees cast their leaves too early. Each twig pinching shut like a jabbed clam. Soon there will be a hot gauze of snow searing the roots. Booze in the spring runoff, pure antifreeze; the stream worms drunk and burning. Tadpoles wrecked in the puddles. Here comes an eel with a dead eye grown from its cheek. Would you cook it? You would if. The people eat sick fish because there are no others. Then they get born wrong. This is not sport, sir. This is not good weather.

Frogs exposed to a mix of pesticides at extremely low concentrations like those widely found around farms suffer deadly infections, suggesting that the chemicals could be a major culprit in the global disappearance of amphibians, UC Berkeley scientists reported Tuesday. When tadpoles were exposed in laboratory experiments to each pesticide individually, 4% died before they turned into frogs. But when atrazine and eight other pesticides were mixed to replicate a Nebraska cornfield, 35% died.

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.

COULDN'T YOU just gag over all this Anna Nicole Smith coverage? Here we have suffered through February, a cruel and chilly month dominated by the underdressed -- Cupid and Oscar strumpets. And the best we can do is tune into this gawd-awful Florida hearing over where they will bury the poor dear, assuming that's even physically possible. The entire nasty episode is exposing us for what we really are, the "trailer trash nation."
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.
