The Genus Gyrocotyle, and Its Significance for Problems of Cestode Structure and Phylogeny (Classic Reprint)


Book Description

Excerpt from The Genus Gyrocotyle, and Its Significance for Problems of Cestode Structure and Phylogeny This investigation has been carried on in the Zoological Labo ratory of the University of California and at the Station of the Marine Biological Association at La Jolla. For material I am indebted to Professor C. A. Kofoid, and through him to the United States Bureau of Fisheries and the Marine Biological Association at La Jolla; also to Professor Jacques Loeb, for privileges at the Herzstein Research Laboratory at Monterey. For substantial assistance in the preparation of drawings for publication I am indebted to Miss E. J. Rigden. For the point ing out of this line of investigation, for help in obtaining the obscure and not easily accessible literature of the subject, and for counsel and encouragement, I wish to express my debt to Professor Kofoid, under whose direction this work has been brought to its present state of completion.

The Genus Gyrocotyle, and Its Significance for Problems of Cestode Structure and Phylogeny


Book Description

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Biology of Turbellaria and some Related Flatworms


Book Description

Turbellaria, the mainly free-living flatworms, and some of their parasitic relatives, are among the simplest of the metazoa and, as such, provide ideal models for a wide range of fundamental studies. The 60 contributions to Biology of Turbellaria and some Related Flatworms cover taxonomy and phylogeny, biogeography and genetics, ecology and behaviour, Anatomy and ultrastructure, development and regeneration, genes and sequences, and neurophysiology. Biology of Turbellaria and some Related Flatworms is the most recent compilation in the series published in Hydrobiologia since 1981, covering research on these flatworms assembled by the world's leading authorities on the group. Audience: These papers present the advanced student and serious researcher with up to date information on an important, but often neglected group whose place in the animal kingdom demands greater attention.




A Functional Biology of Parasitism


Book Description

Series Editor: Peter Calow, Department of Zoology, University of Sheffield, England The main aim of this series will be to illustrate and to explain the way organisms 'make a living' in nature. At the heart of this - their functional biology - is the way organisms acquire and then make use of resources in metabolism, movement, growth, reproduction, and so on. These processes will form the fundamental framework of all the books in the series. Each book will concentrate on a particular taxon (species, family, class or even phylum) and will bring together information on the form, physiology, ecology and evolutionary biology of the group. The aim will be not only to describe how organisms work, but also to consider why they have come to work in that way. By concentration on taxa which are well known, it is hoped that the series will not only illustrate the success of selection, but also show the constraints imposed upon it by the physiological, morphological and developmental limitations of the groups. Another important feature of the series will be its organismic orientation. Each book will emphasize the importance of functional integration in the day to-day lives and the evolution of organisms. This is crucial since, though it may be true that organisms can be considered as collections of gene determined traits, they nevertheless interact with their environment as integrated wholes and it is in this context that individual traits have been subjected to natural selection and have evolved.
