Download or read book Leeches Hirudinea written by K. H. Mann and published by Elsevier. This book was released on 2013-09-11 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Leeches (Hirudinea): Their Structure, Physiology, Ecology and Embryology presents a concise account of the vast knowledge, particularly in the realm of physiology of the Hirudinea. The text provides the various aspects of the life of leeches (Hirudenea). The first three chapters are devoted to the survey of the different families of leeches and the description of Hirudo medicinalis (Medicinal leech). The physiological aspects of leeches such as its circulatory and respiratory systems, muscles, nerves, sense organs, and reproductive processes are elaborated in detail in subsequent chapters. Leech nutrition, behavior, locomotion, and the ways in which the distribution and abundance of leeches is affected by factors of the environment, both living and non-living are elucidated as well. Zoologists will find the book very useful and informative.

This book was released on 2011-06-27 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a result of the European Commission’s concern for the status of continental waters, and as a clear reflection of the notion of water as heritage to be conserved, in the year 2000 the Water Framework Directive (2000/60/CE) was enacted, its goal being to establish a framework to protect water and the different aquatic ecosystems by requiring the Member States to achieve a good ecological status in all their waters by 2015. Like all ecosystems, freshwater ecosystems undergo physical, chemical and energy-related changes, both of natural and anthropogenic origin. These disturbances affect the organisms living in them and those who utilize their resources. Therefore, evaluating these changes has become a very important task in order to better understand aquatic systems. The study and analysis of the ecological status of these ecosystems in relation to their conservation status and water quality is thus a fundamental tool for a more efficient and rational management of their resources, that is, a management that does not threaten the ecosystem. The present guide for the identification of Spanish freshwater macroinvertebrates aims to facilitate the job of those who go to great lengths to identify them in order to then determine biotic indices. It is not the aim of this book to serve as a zoological treaty, nor does it claim to add new information on the biology or the ecology of the taxa covered. This book is, simply, a working tool explicitly designed to facilitate the identification of the Spanish macroinvertebrates and the subsequent computing of biotic indices.

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.

Book excerpt: Armed with razor-sharp teeth and capable of drinking many times its volume of blood, the leech is an unlikely cure for ill health. Yet that is exactly the role this worm-like parasite has played in both Western and Eastern medicine throughout history. In this book, Robert G. W. Kirk and Neil Pemberton explore how the leech surfaces in radically different spheres. The ancients used them in humeral medicine to bring the four humors of the body—blood, phlegm, and black and yellow bile—back into balance. Today, leeches are used in plastic and reconstructive surgery to help reattach severed limbs and remove pools of blood before it kills tissue. Leeches have also been used in a nineteenth-century meteorological barometer and a twentieth-century biomedical tool that helped win a Nobel Prize. Kirk and Pemberton also reveal the dark side of leeches as they are portrayed in fiction, film, and popular culture. From Bram Stoker’s Dracula to a video game player’s nemesis, the leech is used to represent the fears of science run amok. Leech shines new light on one of humanity’s most enduring and unlikely companions.

Download or read book Animal Life in Fresh Water written by Helen Mellanby and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: by Professor L. E. Eastham Formerly Professor of Zoology in the University of Sheffield Most books are written with the intention of supplying some particular need, but few end with such single purpose. Mrs. Mellanby's is no exception, for while the author planned this work to serve as a guide to the school pupil, which function it fulfils in an admirable way, it will also prove of value to the teacher, the university student and the amateur naturalist. While it may be argued that it is not the function of the Uni versities to teach Natural History in the commonly accepted sense, it will always be the aim of Zoologists to know more about animals, what they are and do, where they live and why they live in particular environments. It is unfortunate, in view of the fact that the majority of students of Zoology enter the teaching pro fession, that the increasing load of instruction in morphology, physiology, cytology, genetics, evolution and the like frequently makes a personal study of animal life in relation to environment almost impossible. The fortunate ones visit the sea for a fort night's course in Marine Ecology; the others take posts in schools without even this respite and set about converting their academic learning to a school curriculum. The result is an undesirable and often slavish imitation of university method in the school class room.
