The Center for Biological Diversity filed a lawsuit today challenging the failure of the U.S. Fish and Wildlife Service to develop a national gray wolf recovery plan under the Endangered Species Act.![]()

Recovery plans should describe actions needed to achieve the full recovery of species listed under the Act. But the gray wolf’s outdated recovery plan was developed in 1992 and mostly focuses on Minnesota. It neglects other places where wolves have lived and could recover, like the West Coast, southern Rocky Mountains and northeastern United States.![]()

“The Service can’t rely on its outdated, unambitious, and piecemeal approach to wolf recovery any longer,” said Sophia Ressler, a staff attorney at the Center. “The agency’s refusal to complete a national wolf recovery plan, besides violating the law, neglects both the people who want this majestic species to recover and the wolves who are so important to our country’s biodiversity.”

Parasites May Create Wolf Pack Leaders in Yellowstone![]()

Researchers from the University of Montana and the Yellowstone Center for Resources have found that wolves infected with the parasite Toxoplasma gondii tend to have higher risk-taking behaviors.![]()

According to the study, cougars (Puma concolor) in Yellowstone National Park are known to carry T. gondii. After analyzing blood samples collected from 229 anesthetized wolves and 26 years (1995 to 2020) of behavioral and distribution data, the study authors found that the parasite was more likely to infect wolves living in an area with a higher cougar population. This indicates that wolves may become infected with T. gondii by coming into contact with cougars or simply by being in their environment.![]()

The analyzed data also led researchers to believe that male and female wolves infected with T. gondii displayed more risk-taking behaviors that could ultimately lead to the fitness level of an individual wolf and a pack. Wolves infected with the parasite were more likely to be pack leaders and 11 times more likely to disperse from the pack than uninfected wolves.
