The future is looking brighter for the endangered Mexican gray wolf, as scientists have announced the birth of the first pup of the species to be born from artificial insemination that used frozen semen. 

There are 130 Mexican gray wolves that remain in the wild, largely in Arizona and New Mexico. Some live at the Endangered Wolf Center in Eureka, where the new pup was born. In collaboration with the Saint Louis Zoo, scientists at the center have been collecting and freezing semen from endangered wolves for more than 20 years.

Illinois scientists are studying an endangered species of rattlesnake to find ways to revive its numbers. 

The Eastern massasauga once was widespread in the Midwest, living mainly in the Great Lakes region. Over several decades, its population declined dramatically. The species lives in wetlands, many of which have been drained to to build farms. Northern Illinois University biologist Richard King said it's also the only venomous snake in its range, which has made it a target.

It would be an understatement to call Nick Norman an animal lover. A visit to his family's 200-acre property in St. Clair, Mo., will reveal quickly that his mission in life is to save them.

For example, he has shared his home with Charlie, a 170-pound African spurred tortoise. When Norman found Charlie, he was a malnourished company mascot. Charlie now spends his days marching slowly around Norman's yard, feasting on watermelons.

A group of residents in Franklin County want to sue state and local officials for authorizing a gravel mining project that could threaten the gray bat, an endangered species. 

The Citizens for Preservation of the Meramec River on Aug 3., filed a notice to sue the Missouri Department of Natural Resources, Franklin County Planning and Zoning Commission and Meramec Aggregates, Inc.  The Great Rivers Environmental Law Center is representing the 25-member group.
