July 31, 2009 A new report in the journal Science, crediting good management, says some over-fished ecosystems are improving and fish numbers are up. Marine biologist Boris Worm — who in 2006 warned that without action many fish populations could be gone by 2048 — describes the study's findings.

July 31, 2009 With climate change come the possibilities of changing ocean currents, rising sea levels and shrinking polar ice caps. The Navy has created a task force to examine how climate change might affect national security. Rear Admiral David Titley, heads the task force, and he talks with Steve Inskeep about the challenges of climate change.

A commercial fishing boat pulls in its net near Seattle. Strict federal fishing laws have cut back significantly on overfishing in the United States.
July 30, 2009 In many areas, fishermen are pulling fish out of the seas faster than the populations can withstand, and some fisheries are heading toward collapse. But a major new study shows that all fisheries aren't doomed. In fact, some are on the mend.

July 30, 2009 Researchers believe that some small marine creatures may help curb global climate change. A new study suggests that jellyfish and creatures like them play an important role in circulating ocean waters, mixing nutrients, and helping to reduce CO2 levels in the atmosphere.

Veterinarian Tony Mudakikwa directs Amandine Eriksen and Shannon McFarlin as they excavate the skeleton of a gorilla.
July 30, 2009 We started the morning with two infant burial sites. Life can be rough for little gorillas. For one thing, infanticide is common, just as it is among many primate species.

July 29, 2009 Where graduate student Erin Marie Williams sees a lump on a bone, her senior colleagues see a broken wrist that healed with time. That lump tells the story of a gorilla that walked with a slight limp on the right side and put most of its weight on the other arm.
July 28, 2009 In the Arctic, a change in the weather could mean starvation for herds of musk oxen and other grazing animals. Scientists who study the far north planet have documented "rain-on-snow" events. Rain falls onto the snowpack and freezes into a hard sheet of ice, preventing some wildlife from getting to the plants trapped below.

July 28, 2009 Paleontology student Erin Marie Williams ventures into Rwanda, where she works on a research team exhuming gorilla bones.
July 27, 2009 No mountain gorilla is ordinary, but those found in northwest Rwanda are especially fascinating. They are the gorillas studied by legendary primatologist Dian Fossey — the "gorillas in the mist." Now, researchers are exhuming the descendants of those gorillas, in the search of clues to primate evolution. Researcher Erin Marie Williams is part of that team, and has sent dispatches from the field.
July 27, 2009 Here's a surprise: Wild crows can recognize individual people. But people — even people who love crows — can't recognize individual crows. Here, two experiments that tell the story.

July 25, 2009 Last week, birding counselor Dave Jasper and the kids from the Camp Chiricahua were hiking down Miller Canyon in Southern Arizona when all of the sudden they heard something they weren't supposed to. It was a brown-backed solitaire, a thrush common in Mexico, but one that has never been documented north of the border. Just how Jasper and friends verified their finding could only have happened in this "connected" day and age. Host Scott Simon talks to Jasper about the discovery.

July 25, 2009 Scientists have been playing matchmaker for the "rarest living creature" for more than a decade. Now Lonesome George, the last known Galapagos giant tortoise, may soon become a father. George is somewhere between 90 and 100 years old.

July 23, 2009 Animals often have brilliantly colored or large features that attract mates. Until now, scientists thought the toucan bill was just another one of those pretty characteristics. But it turns out the bill may have another purpose — cooling down the bird.

July 19, 2009 The Obama administration is trying to persuade India to help tackle climate change. Secretary of State Hillary Clinton urged development experts recently to help come up with ideas on projects that could encourage the Indians to turn to clean energy in a way that won't limit its economic growth. NPR Diplomatic Correspondent Michele Keleman reports.

July 19, 2009 Birdwatching might not seem the kind of hobby to attract the Indiana Jones type, but Gerry Nicholls is what you might call an extreme bird watcher. This year he and his friends set out on an international chase for a creature that has never been officially sighted.
