Pascal Lamy, the director general of the World Trade Organization, has the task of managing the complex negotiations.

For ministers preparing for new negotiations starting Monday, the good news is that their meeting room will be air-conditioned. The bad news is that it may be even more crowded

Gray wolves in the greater Yellowstone area of the northern Rocky Mountains, which would have been fair game for hunters in three states as a result of a federal government decision in March, were again put under the protections of the Endangered Species Act by a judge in Montana on Friday.

The action by the judge, Donald W. Molloy of Federal District Court, took the form of a preliminary injunction and could be reversed. But Judge Molloy's language showed serious reservations about the Fish and Wildlife Service's decision to remove endangered species protections for the wolves.
