( Below: A factory fishing vessel scours a remote Antarctic bay.) Terri Gross' producers find her the most interesting, and occasionally terrifying guests. Earlier this week, she interviewed author/scientist Daniel Pauly , who had some really dreadful news about the consequences of over-fishing, and not mererly the fisheries we know are damaged, but for the whole fuukin' ocean.

The aquatic ecosystems of Antarctica keep turning up surprises for scientists, who have found flourishing ecosystems comprised mostly of microorganisms. A new paper, published in Science , examined samples drawn from an Antarctic lake and tracked seasonal changes in the viruses that prey on these bacteria. They found large, diverse populations of viruses, some of which have never been seen underwater...

Gannets on the island of Malgas in South Africa are in a bit of a pinch. Usually they nest with one parent out fishing, while the other parent guards the chick. However, fewer fish to catch means both parents have to go hunting and leave the chick unguarded. This leaves an opportunity open for pelicans who have adopted a bizarre survival strategy. Rather than fly out to fish for themselves, they're...

By JUDITH KOHLER, Associated Press Writer Judith Kohler, Associated Press Writer – Thu Nov 5, 4:51 pm ET DENVER – Airborne nitrogen pollution from vehicle exhaust and farm fertilizer is turning algae in the alpine lakes of Rocky Mountain National Park into junk food for fish, a study says. A similar phenomenon is occurring in Sweden and Norway, according to the study of about 90 high-elevation...

Mojave Desert research shows that nitrogen is second only to water in importanceIn the Mojave Desert winds howl across this hottest place in North America, blowing sands across Death Valley and through empty ghost towns, swirling across treeless land for hundreds of miles. But even in the otherworldly Mojave, life thrives. The Joshua tree (Yucca brevifolia), an indicator species for this desert, defines...

In foods, soil samples or customs checks, plant fragments sometimes need to be quickly identified. The use of DNA "barcodes" to itemize plant biodiversity was proposed during the 1992 Rio de Janeiro Summit. Researchers have now tested this method in the tropical forest.
