WASHINGTON -- The debate over the fence the United States is building along its southern border has focused largely on the costs, feasibility and how well it will curb illegal immigration. But one of its most lasting impacts may well be on the animals and vegetation that make this politically fraught landscape their home. Some wildlife researchers have grown so concerned about the consequences of bisecting hundreds of miles of rugged habitat that they have talked of engaging in civil disobedience to block the fence's construction. "This wall is so asinine and so wrong, I am one of a dozen...

Scientists in Germany have discovered that ordinary plants produce significant amounts of methane, a powerful greenhouse gas which helps trap the sun's energy in the atmosphere. The findings, reported in the journal Nature, have been described as "startling", and may force a rethink of the role played by forests in holding back the pace of global warming. And the BBC News Website has learned that the research, based on observations in the laboratory, appears to be corroborated by unpublished observations of methane levels in the Brazilian Amazon. Until now, it had been thought that natural sources of methane were mainly...

LOS ANGELES – Los Angeles International Airport will spend $200,000 to uproot and replant dozens of palms trees that it illegally planted around the airfield five years ago. "We are delighted that they're following through, to right the wrong that was done," said Travis Longcore, science director of The Urban Wildlands Group, which first challenged the project. "We're very happy that it's moving forward." LAX officials expected the 92 Mexican fan palms would spruce up a grungy stretch of land just outside the airfield's chain-link fence. But some nearby residents complained that the tall palms blocked ocean views. The Urban...
