Available in PDF, EPUB and Kindle. Book excerpt: This book, published in two volumes, provides the most comprehensive review of lamprey biology since Hardisty and Potter’s “The Biology of Lampreys” published more than 30 years ago. This second volume offers a synthesis of topics related to the lamprey gonad (e.g., lamprey sex ratios, sex determination and sex differentiation, sexual maturation, and sex steroids), the artifical propagation of lampreys, post-metamorphic feeding and the evolution of alternative feeding and migratory types, the history and status of sea lamprey control in the Laurentian Great Lakes and Lake Champlain, and an overview of contributions of lamprey developmental studies for understanding vertebrate evolution.
Download or read book Biology of the Sea Lamprey in Its Parasitic Phase written by Phillip Sheridan Parker and published by . This book was released on 1956 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of the experimental lampreys were mature and rip after 14 to 18 months of parasitic life. They exhibited signs of irreversible physical degeneration which precedes death. Three specimens were immature at 14, 18, and 26 months in aquariums, thus indicating that under certain conditions, lampreys may extend their parasitic phase.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Lampreys written by Raymond Moss and published by Nova Science Publishers. This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: At present, two native lamprey species occur in the Czech Republic, namely the brook lamprey and the Ukrainian lamprey. Lampreys: Evolution, Distribution and Use in Research begins by summarizing the available knowledge about the biology, ecology, distribution, monitoring of occurrence and action plans/recovery programmes for the aforementioned species.Following this, the occurrence of lampreys of the genus Lethenteron in 19 rivers and one lake in Sakhalin Island is documented, and sex differences in adults in respect to morphometric parameters are also presented.Mammalian blood clotting is presented as an extremely complex phenomenon involving more than two dozen proteins interacting in a series of limited proteolytic events partitioned into two calcium-dependent pathways. Some clotting proteins in mammals are present in only trace amounts, and proving their absence or presence in lampreys was not possible until the era of whole genome sequencing. As such, the authors retrace this development from a personal standpoint.
Download or read book Leeches Lice and Lampreys written by Graham C. Kearn and published by Springer Science & Business Media. This book was released on 2007-11-05 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many different kinds of animals have adopted a parasitic life style on the skin and gills of marine and freshwater fishes, including protozoans, flatworms, leeches, a range of crustaceans and even some vertebrates (lampreys). There is a parasitic barnacle, described first in the 19th century by Charles Darwin, fish lice that change sex and bivalve molluscs parasitic only when young. This book explores for the first time in one volume, the remarkable biology of these little known and frequently bizarre animals. The following closely interwoven themes are considered for each group of parasites: how they find their hosts, how they attach, feed and reproduce, the damage they inflict and how the host’s immune system retaliates. Based on the British fauna, but extending where appropriate to examples from North America, Australia and elsewhere, the book is essential reading, not just for the professional parasitologist, but also for anyone interested in fishes and in this neglected field of British natural history. With the enquiring naturalist in mind, terms and concepts are explained as they arise, backed up by a glossary, and the text is liberally illustrated. An introductory chapter on fish biology sets the scene and common fish names are used throughout, as well as scientific names.
Download or read book Jawless Fishes of the World written by Richard Beamish and published by Cambridge Scholars Publishing. This book was released on 2016-02-29 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hagfishes and lampreys, both examples of jawless fishes, are elongated, eel-like animals lacking paired fins, and are the only living representatives of ancient creatures that gave rise to current species of fish and, eventually, humans. This volume provides an overview of the current status of knowledge on a variety of topics related to jawless fishes, including their taxonomy, zoogeography, phylogeny, molecular biology, evolution, life history, role in the ecosystem, and fisheries and management of hagfishes and lampreys worldwide. This is the first book dealing exclusively with the various aspects of jawless fish species throughout the world. It brings together a number of papers providing new data on jawless fishes, and offers readers a range of useful information within a single reference, reflecting the growing appreciation for hagfishes and lampreys worldwide.
Download or read book Lampreys written by M. W. Hardisty and published by . This book was released on 2006 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although, in the recent past they may have been one of the most numerous and widespread inhabitants of our cleaner rivers, it is their mode of life that explains why they are so seldom seen by a casual observer. The chief characteristic and the one that has contributed most to their survival is that 60-80% of their entire lifespan is spent as a distinctive blind, larval stage known as the ammocoete. Even during the adult stage, this is a wholly nocturnal creature, passing its existence burrowed under the banks of mud along the sides and bottoms of rivers. Lampreys occupy a key position in our evolutionary story and can be grouped with a select number of animal species, commonly referred to as 'living fossils'; among these are the ancient king crab, the coelacanth and the lungfish. All have relatively long evolutionary histories and still show some of the primitive characteristics that are seen in similar and related fossil animals.
