DOWNLOAD EBOOKIn The Wrong Place: Alien Marine Crustaceans - Distribution, Biology And Impacts provides a unique view into the remarkable story of how shrimps, crabs, and lobsters – and their many relatives – have been distributed around the world by human activity, and the profound implications of this global reorganization of biodiversity for marine conservation biology. Many crustaceans form the base of marine food chains, and are often prominent predators and competitors acting as ecological engineers in marine ecosystems. Commencing in the 1800s global commerce began to move hundreds – perhaps thousands – of species of marine crustaceans across oceans and between continents, both intentionally and unintentionally. This book tells the story of these invasions from Arctic waters to tropical shores, highlighting not only the importance and impact of all prominent crustacean invasions in the world's oceans, but also the commercial exploitation of invasive crabs and shrimps. Topics explored for the first time in one volume include the historical roots of man's impact on crustacean biogeography, the global dispersal of crabs, barnacle invasions, insights into the potential scale of tropical invasions, the history of the world's most widely cultured shrimp, the invasive history and management of red king crabs in Norway, Chinese mitten crabs in England, and American blue crabs in Europe, the evolutionary ecology of green crabs, and many other subjects as well, touching upon all ocean shores.

DOWNLOAD EBOOKThis book describes a wide variety of speculations by many authors about the consequences for humanity of coming into contact with extraterrestrial intelligence. The assumptions underlying those speculations are examined, and some conclusions are drawn. The book emphasizes the consequences of contact rather than the search, and takes account of popular views. As necessary background, the book also includes brief summaries of the history of thinking about extraterrestrial intelligence, searches for life and for signals, contrasting paradigms of how contact might take place, and the paradox that those paradigms allegedly create.

DOWNLOAD EBOOKFrom killer toads, feral felines, and brown tree snakes to multiple invaders in the Great Lakes and Lake Victoria, Alien Invaders explores the impact on our ecosystems of the wave after wave of invaders and why they have become a worldwide concern. Environmentalists Jane Drake and Ann Love take us on a journey from the days of sailing ships and shipboard rats to the fungus that sparked the Irish potato famine to the beautiful but deadly purple loosestrife strangling native wetlands, while presenting the concepts of biodiversity and endangered species. Learn where the invaders originate, how they travel, what they displace, why the invaded natural system is vulnerable, and what can be done. Discover if you are an invader or a saver and how you can help.
