Book excerpt: Excerpt from Morphology of Invertebrate Types Owing to the rapid advance of Experimental Zoology, the older branches of morphological study such as Comparative Anatomy and Embryology, have been left in the background. In order to acquire familiarity with modern methods and problems, it became necessary to curtail the time allotted to Morphology. As a natural consequence the laboratory guides in general use in this country are more elementary than is de sirable. The result has proved in many ways unsatisfactory. The student is left with only a superficial knowledge of the structure, life and development of those very animals which in his later studies he is going to use for experiments. But the high tide in Experimental Zoology has been reached and passed. A general tendency to return to morphological studies is manifest in recent years in the great increase in the number of papers dwelling upon the anatomy of invertebrates. It seems, therefore, desirable to place in the hands of the student, a manual which will enable him to lay the foundation for a knowledge of invertebrate anatomy.

It seems, therefore, desirable to place in the hands of the student, a manual which will enable him to lay the foundation for a knowledge of invertebrate anatomy. The usual method of teaching this subject consists in having the student dissect a series of types, but while doing this he is supposed to pay attention only to structures of a general character and to skip details. This method is open to grave criticism. Generalization should come as the result of extended observation. If we substitute generalization for observation, we do the student's work for him and defeat our own end. By this I do not mean to say that the student should be offered only a knowledge of minute facts and left to his own resources to sift the material and draw conclusions. On the contrary!

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Text-Book of Invertebrate Morphology The Morphology of Invertebrate Animals may be treated either from the standpoint of Comparative Anatomy or from the zoological side, and either method of treatment has much to recommend it. In my experience, however, the zoological method has proved most satisfactory for the presentation of the subject to students, inasmuch as it is necessarily the method employed in the laboratory, and accordingly in the present work that plan of presenting the facts of morphology has been followed. A bare statement of the structural peculiarities of the various groups, however, is simply collecting the bricks and stones without the mortar necessary to unite them together into a substantial edifice, and where the opportunity has presented itself attention has been directed to the comparative significance of various organs and to the affinities of the various groups. A word is perhaps necessary in regard to the classification adopted,which presents many radical changes from the schemes usually employed. For the larger groups, following the example of Claus, the term type has been employed, and no less than twelve of these types are adopted. This increased number has resulted from a division of two groups usually recognized, namely, the Vermes and the Arthropod. As regards the former it has long been acknowledged to be a heterogeneous collection, and its retention is to be regarded as a survival. It is true that the forms assigned to it do present certain phylogenetic affinities; but if this is to be the reason for its retention, then the Mollusca and Prosopygia (Molluscoidoa) should also be assigned to it. It has seemed more satisfactory to retain the Mollusca and Prosopygia as distinct groups, and to divide the Vermes into several types, such as the Platyhelmiuthes, Neinathelminthes, and Annelida, each of the same rank as the Mollusca, and presenting approximately similar degrees of affinity among themselves.

Download or read book Thorp and Covich s Freshwater Invertebrates written by James H. Thorp and published by Elsevier. This book was released on 2014-09-06 with total page 1149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Readers familiar with the first three editions of Ecology and Classification of North American Freshwater Invertebrates (edited by J.H. Thorp and A.P. Covich) will welcome the comprehensive revision and expansion of that trusted professional reference manual and educational textbook from a single North American tome into a developing multi-volume series covering inland water invertebrates of the world. The series entitled Thorp and Covich’s Freshwater Invertebrates (edited by J.H. Thorp) begins with the current Volume I: Ecology and General Biology (edited by J.H. Thorp and D.C. Rogers), which is designed as a companion volume for the remaining books in the series. Those following volumes provide taxonomic coverage for specific zoogeographic regions of the world, starting with Keys to Nearctic Fauna (Vol. II) and Keys to Palaearctic Fauna (Vol. III). Volume I maintains the ecological and general biological focus of the previous editions but now expands coverage globally in all chapters, includes more taxonomic groups (e.g., chapters on individual insect orders), and covers additional functional topics such as invasive species, economic impacts, and functional ecology. As in previous editions, the 4th edition of Ecology and Classification of North American Freshwater Invertebrates is designed for use by professionals in universities, government agencies, and private companies as well as by undergraduate and graduate students. Global coverage of aquatic invertebrate ecology Discussions on invertebrate ecology, phylogeny, and general biology written by international experts for each group Separate chapters on invasive species and economic impacts and uses of invertebrates Eight additional chapters on insect orders and a chapter on freshwater millipedes Four new chapters on collecting and culturing techniques, ecology of invasive species, economic impacts, and ecological function of invertebrates Overall expansion of ecology and general biology and a shift of the even more detailed taxonomic keys to other volumes in the projected 9-volume series Identification keys to lower taxonomic levels
