In the News: UMN researchers identify new strain of deadly pig virus in U.S.

Porcine epidemic diarrhea virus (PEDv) has resulted in the deaths of millions of pigs and piglets since its introduction to the United States in early 2013. Since its introduction, the University of Minnesota has been on the frontline of PEDV disease spread prevention research with the development of rapid detection and herd surveillance tests.

University of Minnesota College of Veterinary Medicine experts have now contributed to PEDV understanding by detecting a new, third strain of the disease on a Minnesota hog farm. The strain was found to be at least as virulent as the original strain that emerged in the U.S. in early 2013, according to Reuters.

Searching for ways to eliminate invasive rats, without adding new threats to island ecosystems

Invasive rodents are a problem for oceanic islands throughout the world. Rats transported by sea-faring humans from landmass to landmass plague ecosystems off the coast of Australia and in the Hawaiian and Galápagos Islands. Rats can endanger native species, damage agriculture crops and even prevent trees from re-growing. Efforts to remove the invasive species, however, sometimes result in their own unintended consequences.

“You can’t just remove 70 percent or 90 percent,” said Julia Ponder, D.V.M., executive director of The Raptor Center at the University of Minnesota College of Veterinary Medicine. “You have to remove 100 percent of the invasive species, and that’s what makes it so hard. There’s no margin of error and eradication efforts are expensive.”

Eradication efforts can put other species such as birds at risk, too.

That’s why Ponder became involved in research recently published in the journal Biological Conservation.

What happens to a rehabilitated eagle after release?

Each year in September, The Raptor Center at the University of Minnesota releases a small number of rehabilitated birds back to the wild at Carpenter St. Croix Valley Nature Center in Hastings, Minnesota. While a few thousand spectators come out to observe the release and see education birds including bald eagles, great horned owls and kestrels up-close, it’s not often that the audience gets to learn what happens in the days, weeks and months following.

Did the bird make it? Did it fall prey to another urban landscape challenge such as a chimney, window or methane burner? Or is the bird we saw fly free in good health, hunting and soaring over the plains?

For one bird released in July, there was a rare opportunity to find out.
