Wolves could expand across the eastern U.S.—but they might need help

Gray wolves could thrive in the eastern United States well beyond their current range in the Great Lakes region, but they might have a hard time reaching other suitable habitats without human intervention, researchers say. Wolves once had the largest known range of any land mammal but they were nearly exterminated in the United States in the early 1900s after persecution by humans. 

Their population only recovered after they were placed under federal protection in the 1970s. They have since recolonized some areas where they once flourished, including in Minnesota, Wisconsin and the Upper Peninsula of Michigan. 

A 2022 study analyzed which areas in the eastern U.S. still have suitable habitat for wolves and are connected enough to each other so wolves might be able to travel between them. 

To do that, the researchers used survey data collected between 2018 and 2020 by biologists working for the natural resource departments in Minnesota, Wisconsin and Michigan. 

They then modeled the characteristics of the habitats where wolves were found and predicted where else in the eastern U.S. large tracts of suitable areas occur. They also modeled how connected to each other those areas are. They found that six areas had good habitat and were large enough to sustain wolves, but the animals occur in only one of them, the western Great Lakes.

Fraudsters face sentencing in fake green energy venture

Two men who admitted conspiring to commit mail and wire fraud await sentencing for cheating 22 investors out of more than $2 million from June 2016 to April 2018. Former Pittsburgh resident Jonathan Freeze and Kevin Carney of Euclid, Ohio, have pleaded guilty in federal court in Pittsburgh. Freeze, Carney, and a third defendant, Robert Irey, who died after also pleading guilty, created a business called Alternative Energy Holdings to use investments from their victims to build plants that would convert biodegradable waste into renewable energy, according to the U.S. Department of Justice. According to the department, they promised high rates of returns to prospective investors who made short-term loans. The three defendants assured those investors that they would use all of the loan money for the company.

Students at Michigan State and Wisconsin win EPA funding for environmental health innovations

Student researchers from Michigan State University and the University of Wisconsin are among the winners of an Environmental Protection Agency contest for innovations in sustainability. Muhammad Rabnawaz, an associate professor of packaging at Michigan State, brainstorms with his team

The EPA established the People, Prosperity and the Planet Student Design Competition to support teams of undergraduate and graduate students working to develop solutions to environmental and public health challenges. The latest round of grants, announced in September, provided around $100,000 each for teams that previously received up to $25,000 from the agency for promising projects. Michigan State’s team is working to create more sustainable materials for disposable cups, takeout containers and other single-use items. Today many of those products are made with microplastics and per- and polyfluoroalkyl substances, or PFAS, known as “forever chemicals” due to their extremely slow breakdown in the environment. The team is developing fiber-based and paper packaging that works as well as plastic without using harmful substances.
