“We’re now seeing overlap competition they’re starting to graze in the same area,” Arce says. Moose and hares consume similar vegetation and mostly coexisted alongside each other until recently, says Ana Arce, a 2021 Mosaics in Science Diversity intern who studied and reported on snowshoe hare populations in the park. Years of increasing moose population have led to insufficient food resources, which is beginning to affect other members of the Isle Royale food chain, including snowshoe hares. ( This group is making the outdoors more accessible to people of color in Michigan.) As a result, the park instituted a gradual reintroduction of wolves in 2018. “Mainland wolves have not been able to visit the island to breed and increase the genetic variation of the island wolves,” Kemmet says, noting this contributed to the park’s dwindling wolf populations. In the 1960s, ice bridges occurred in two out of three winters. Winter ice bridges from the mainland, which is how wolves arrived here in the first place, now only form about every 10 years. Recently however, the wolves’ main mode of travel to Isle Royale has become limited. Isle Royale’s wolves have long kept the moose population in check by reducing the likelihood of overgrazing and future food scarcity. He recently filmed Wolves of Isle Royale: The Quest for Survival, a 2021 National Geographic Society-funded documentary. “On this island, an increase of a few degrees in air temperature has had monumental effects,” says Slade Kemmet, a National Geographic Explorer studying the effects of climate change on national parks.

This groundbreaking discovery inspired scientists to reevaluate the causes of arthritis in humans, too. Bone analysis has helped researchers pinpoint a likely cause: malnutrition due to severe winters and food competition. Take arthritis, a common ailment among Isle Royale moose. These skeletons have led to key findings about both moose and human health. “After the moose have died, we reconstruct the population using bones of moose we find on the ground,” says Peterson. With incisors alone, researchers can determine the age and health of a moose. Volunteers collect moose skulls, jawbones, metatarsus, and any other bones that show signs of arthritis. Without volunteer scientists, who collect most of the bones, a study of this scope would be near impossible, says Rolf Peterson, a researcher with Michigan Technological University who’s been working on the study for decades.

As the climate-change crisis continues, conducting this research is becoming increasingly more necessary to protect the island. Bones, the foundation of the wolf-moose research, have unlocked monumental discoveries about Isle Royale’s ecology and even insights into human health. Moosewatch Expeditions is one of the most immersive ways for travelers to participate in the world-renowned study. Since 1958, researchers have used this 45-mile-long, far-flung island as a living laboratory to study the relationship between the island’s most famous inhabitants: wolves and moose.

Viscious is soon an understatement.Their reward is contributing to the longest-running predator-prey study in the world. You play as Morgan Yu Prey takes place primarily on the space station, Talos I, where research into these viscious life-forms known as the Typhon has taken place. PREY (Released May 5, 2017), developed by Arkane Studios and published by Bethesda Softworks, is a Sci-Fi action game set in an alternate timeline in the near future.
