A well-known wildlife biologist was sentenced Tuesday to three years probation and a $7,500 fine for not following federal and state laws about catching and banding golden eagles. John David Bittner, 68, of Julian captured and banded birds without federal or state permits and failed to send carcasses to the National Eagle Repository as required by law. Bittner had pleaded guilty to one count of the unlawful taking of a golden eagle in violation of federal law. U.S. Magistrate Judge David Bartick, in San Diego federal court, said Bittner seemed to put his financial interests ahead of rules meant to help the survival of the eagles.

Say you could hop into a DeLorean and travel back to when life on Earth began. Would fish migrate from water to land? Would the dinosaurs go extinct? At the end of our trip, would we still encounter life as we now know it? Some scientists don't think so. They argue that any number of chance events - storms and earthquakes, for example - would steer evolution down another course, making it impossible to predict. But a study published Tuesday in Science has found that if we know the ecology of an area, we can predict the traits a species will evolve millions of years from now, despite all the chance events that could influence the outcome.

Southern California's mountain yellow-legged frog has made a remarkable leap toward recovery for an endangered species, rebounding in just two years from near-extinction brought on by development, fires, fungal infections and predatory trout, federal biologists said on Monday. In 2010, only 200 remained in isolated wild populations, prompting federal wildlife authorities and zoos in Fresno, Los Angeles and San Diego to launch an ambitious recovery program that included captive breeding facilities, trout removal programs and barring public access to areas where frogs were clinging to existence.

GRAND CANYON, Ariz. -- Eric York was obsessed with the big cats -- their health, temperaments and survival rates amid the park's annual tourist invasion. For years, he wandered the area's crags, gullies and woods, tracking and tagging the region's last remaining mountain lions as a biologist for the Grand Canyon National Park. In 2007, tragedy struck. At age 37, the Massachusetts native was killed doing the job he loved, but not in the way people might guess. He wasn't mauled by a lion, but fell victim to a case of pneumonic plague he contracted doing a necropsy on a dead female cat. Because the park lacked a forensic lab, York did his postmortem for the mountain lion research program in the garage of his home in the village of about 2,000 park employees.

Marine biologist Dan Madigan stood on a dock in San Diego and considered some freshly caught Pacific bluefin tuna. The fish had managed to swim 5,000 miles from their spawning grounds near Japan to California's shores, only to end up the catch of local fishermen. It was August 2011, five months since a magnitude 9 earthquake and tsunami had struck in Japan, crippling the Fukushima Daiichi power plant. Madigan couldn't stop thinking about pictures he'd seen on TV of Japanese emergency crews dumping radioactive water from the failing reactors into the Pacific Ocean.

When James Watson and Francis Crick deciphered the structure of DNA in 1953, their discovery answered a crucial question in biology: How is genetic information passed down from parent to child? Their work also created conundrums, however. They and others showed that every cell of an organism contains all of its genetic material. How, then, does an individual cell know which genes to use and when? And how does information from DNA get to the cell's protein-making machinery? The seminal insight into those questions came from three biologists at the Pasteur Institute in Paris - Dr. Francois Jacob, Jacques Monod and Andre Lwoff.
