...salt water. Fish and crabs might last for a year, but the air-breathing sea mammals that eat them will not. "The seals are exhausted from diving through that extra 50 ft. of freshwater before they can reach salt water and maybe find something to eat," says Marine Biologist Tamra Faris of the National Marine Fisheries Service. On her last flight over the lake in mid-July, Faris counted seven harbor porpoises and three Dall's porpoises; last week the porpoises could be seen cruising back and forth along the glacial dam, searching in vain for a passage back...
Then, 10,000 or more years ago, man joined forces with nature to maintain the prairie ecosystem. "A spark from an Indian campfire or a bolt of lightning, and the prairie was ablaze," says Northeastern Illinois University Biologist Robert Betz. The fires, Betz explains, were a natural part of the system, favoring the growth of deep-rooted species that could easily survive the repeated conflagrations. A startling variety of plants and flowers flourished under these conditions, their roots creating a dense, interlocking mass that reached as far as twelve feet underground. Between blazes, the prairies teemed with quarry...
...week's end, both in the U.S. and abroad, the need for a medical answer to the AIDS crisis was becoming more and more urgent. As the Paris meeting concluded, Molecular Biologist Flossie Wong-Staal of the National Cancer Institute tried to sound optimistic. "I think things are going on the right track and the right time schedule. The science is going very fast." Unfortunately, she conceded, "the disease is going faster...
...Biologist Stewart Fefer and three colleagues from the U.S. Fish and Wildlife Service had eagerly anticipated their assignment: a trip to Laysan, a 960-acre island about 1,000 miles northwest of Honolulu. They were to study some of the 14 million seabirds that nest there, and they looked forward to their stay on what they assumed would be an island paradise with pristine beaches. What they discovered came as a shock. The sands of Laysan were strewed with an unbelievable variety of plastic trash. While doing his bird-watching chores, Fefer cataloged thousands of pellets as well...
...ubiquitous form of plastic trash is the tiny polyethylene pellets used in the manufacture of plastic items. In one survey, researchers calculated that, on average, a square mile of the Sargasso Sea, southeast of Florida, contained between 8,000 and 10,000 bobbing pellets. Says Al Pruter, a fishery biologist and partner in a Seattle-based natural- resources consulting firm: "Almost without exception, surveys show plastic to account for over one-half the man-made products on the ocean surface...
