ROB CHANEY A nationwide collection of biologists has called on the U.S. Department of Interior to restore Endangered Species Act protection to gray wolves, in light of recent state actions against the animals. The 115 signers include at least eight in Montana, including former U.S. Fish and Wildlife Service gray wolf deputy recovery coordinator Joe Fontaine and Carter Niemeyer, who led wolf trapping and control operations in Montana for 26 years. Natural history scientists and authors Doug Chadwick and Cristina Eisenberg of Montana are also on the list. Michigan Technological University distinguished professor John Vucetich and Ohio State University professor Jeremy Bruskotter led the effort.
