However, cattle ranchers in this area have made a determined effort to exterminate wolves. From 1918 to the present, approximately 67% of wolves in the region are male, and 33% are female. Biologists suspect that male wolves are more likely than females to return to an area where the population has been greatly reduced. (Round your answers to four decimal places.) \r<BR>\n" );
