Author's Note: How Invasive Species Work

I got my first taste of what an alien species can do to the environment back in the mid-1980s when I worked in a one-person bureau for a daily newspaper in the Adirondacks of New York. One day Edmund Morette, one of the fish and game types who populated the area, walked into my office with a package wrapped in newspaper. He slammed the weighty paper on my desk and opened it. Inside was a 10-pound salmon. "Undie," I said, using his nickname, "what are you doing?" I was incredulous that he had brought a dead fish into my office. "Take a picture, John," he said, pointing to the suction marks on the salmon's body. Undie said a lamprey eel in Lake Champlain had taken hold of the fish and wouldn't let go. The eel killed the fish. I took the picture and spent the next several years writing about various invasive species that threatened the region.
