Great Lakes Sea Lamprey: The 70 Year War on a Biological InvaderThe stuff of nightmares in both their looks and the wounds inflicted on their victims, sea lampreys (Petromyzon marinus) are perhaps the deadliest invasive species to ever enter the Great Lakes. At the invasion's apex in the mid 20th century, harvests of lake trout (Salvelinus namaycush), the lampreys' preferred host fish in the Great Lakes, plummeted from peak annual catches of 15 million pounds to just a few hundred thousand pounds per year a drop
The stuff of nightmares in both their looks and the wounds inflicted on their victims, sea lampreys (Petromyzon marinus) are perhaps the deadliest invasive species to ever enter the Great Lakes. At the invasion's apex in the mid-20th century, harvests of lake trout (Salvelinus namaycush), the lampreys' preferred host fish in the Great Lakes, plummeted from peak annual catches of 15 million pounds to just a few hundred thousand pounds per year--a drop of 98% in only a few decades. Threatening the complete collapse of the fishery, the sea lamprey invasion triggered an environmental awakening in the region and prompted an international treaty that secured unprecedented cooperation across political boundaries to protect the Great Lakes. Fueled by a pioneering scientific spirit, the war on Great Lakes sea lampreys led to discoveries that are the backbone of the program that eventually brought the creature under control and still protects the largest freshwater ecosystem in the world to this day. Great Lakes Sea Lamprey draws on extensive interviews with individuals who experienced the invasion firsthand as well as a trove of unexplored archival materials to tell the incredible story of sea lamprey in the Great Lakes--what started the invasion, how it was halted, and what this history can teach us about the response to biological invaders in the present and future. Richly illustrated with color and black & white photographs, the book will interest readers concerned with the health of the Great Lakes, the history of the conservation movement, and the ongoing threat of invasive species.Binding Type: Hardcover

Not for tough chewers
Color: Blue
Cute toy, good concept but definitely not for super chewer. Got it at such a price that I let him destroy it because he was having so much fun. You only have one birthday a year after all.

fun toy
Color: Orange
Very cute toy .My dog loves it. He is hard on toys and loves playing pully. So far it is holding up really well. It is a
good size for medium to large dogs. I think if you have a small breed it may be to large. The color is a vivid orange and white.
I really think your dog will love it.
