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

great dog toy
Color: Blue
My dog loves it. It's really crunky. nicely made.
only 4 stars because of packaging, careful if opening plastic bag with scissors, really stuffed in a very small bag.

My Yorkie’s new favorite toy
Color: Orange
This octopus toy was an instant hit with my Yorkie! The size is perfect for a small dog, and he loves carrying it around the house and tossing it in the air. I really appreciate that it has no stuffing, which means less mess if he gets a little too enthusiastic with his playtime.
The material feels durable, and the toy has held up well to daily play. It’s soft enough for cuddling but sturdy enough for tugging and chewing. The squeakers keep him entertained and engaged, and he always gets excited when I bring it out.
Overall, this is a fun, well-made toy that keeps my Yorkie happy and occupied. I would definitely buy it again.

Octopus dog toy
Color: Blue
My chihuahua loved it but didn’t last very long. Not very durable and was very small. He was able to get the plastic material out fairly quickly.
