French Fries and Brown Trout

A handful of folks are aware that the roof of the Sears building on Roosevelt Boulevard in Key West is a key nesting ground for the least tern, which prefers a flat, pebbly surface for egg laying. But scientists might add it to their list of examples of “biotic homogenization.” “‘On average, pairs of states have 15.4 more species in common now than before European settlement of North America,’ said the University of Wyoming’s Frank Rahel, in a study published in the journal Science.”
Does this mean that brown trout — probably responsible for replacing more native fish than we are aware of in the U.S. — is the big box retailer of trout species? Amanda Onion of ABC News.
