New Arctic Shipping Lanes Could Leave them Open to Invasive Species Spread
Experts are warning that the new Arctic shipping routes that have opened up as ice-ways continue to melt create new opportunities for invasive marine and insect life to spread further north.

A. Whitman Miller and Gregory M. Ruiz of the Smithsonian Environmental Research Center have recently issued a warning to their fellow scientists that the increasing popularity of two new Arctic shipping routes for commercial trade will significantly raise the likelihood that new invasive species will make their way into harbors they were never able to reach prior to 2009.

The arctic routes are consistently cold. As long as a species can survive cold temperatures of a "short" trip across the northern hemisphere, they will find themselves in unexplored and vulnerable waters in no time.

Stormwater Pollution is Killing Coho Before Spawning - Researchers at NOAA’s Northwest Fisheries Science Center in Seattle worked with collaborators, including the U.S. Fish and Wildlife Service, local tribes and the Wild Fish Conservancy, to survey 51 sites from 2000 to 2011 in streams all over the Puget Sound basin. They used the survey data with a new computer model to map predicted coho death rates. The results show that in an estimated 40 percent of their range in the Puget Sound Basin, 10 to 40 percent of coho salmon die before they can even spawn because of pollution.
