Fighting invasive species on one island led to plan for all

Researchers recently laid out a strategy to show people how to rid Great Lakes islands of invasive plants and animals. “We always felt that the state wasn’t going to ride in on a white horse and solve all of our problems because we are in the middle of Lake Michigan,” said Pamela Grassmick, who started a grassroots educational campaign to treat invasive species on northern Beaver Island. It inspired scientists to develop a defense against invasive species that can be replicated at other islands. Michigan has 1,709 islands, but 14 comprise 90% of the state’s entire island area.

Isle Royale squirrels may have swum from mainland

Isle Royale may be biologically less isolated and more connected than scientists believed. A new DNA study of its thriving red squirrel population discovered that it’s not a unique subspecies as long thought, but is related to mainland squirrels as far away as Labrador. It may have swum or crossed an ice bridge or have been introduced by humans. The results are important because they show “how dynamic and connected this island is with the mainland.” An Isle Royale National Park wildlife biologist explains. By Eric Freedman.

The dose is in the bite: silent effects of parasitic sea lamprey

The parasitic sea lamprey kill a lot of lake trout in the Great Lakes, and those that survive the attack suffer long-lasting damage. Michigan State University researchers found that, even a year after an attack, lamprey victims produce much less sperm than those that haven’t been attacked. The severity of the wound influences the magnitude of health consequences. By Michaela Kratofil
