This book was released on 2017-09-16 with total page 288 pages. Available in PDF, EPUB and Kindle. 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.

Book excerpt: Excerpt from A d104-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 collect ing 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.

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!

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 A Manual of the Common Invertebrate Animals written by Henry Sherring Pratt and published by . This book was released on 2015-07-21 with total page 754 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Manual of the Common Invertebrate Animals: Exclusive of Insects This manual has been written to supply the need which has been felt in this country for a long time of a book containing descriptions of the common invertebrate animals, by means of which their names and affinities can be determined. Excellent general manuals with analytical keys for the identification of the common insects already exist, but a person wishing to identify animals belonging to most of the other invertebrate groups must usually have recourse to technical papers and treatises which are for the most part inaccessible except to specialists. The book is intended more particularly for use in the eastern and central portions of the United States and Canada, and the endeavor has been made to include in it most of the common invertebrates except insects occurring in this region. In addition to these, representative species occurring in the western states and on the Pacific slope are included, as are also other species to which some special interest attaches and which are found in other parts of the world. Animals which inhabit the deep sea have not been included except in special cases where they are representative of their particular groups. The general plan of the book is similar to that of Leunis' Zoologie, a standard German work which has for two generations supplied the need of a general synopsis of animals in Europe, and has been extensively used elsewhere throughout the world. As in that work, the analytical tables and descriptions of species of each of the larger groups of animals are preceded by a morphological description of the group together with some account of the habits and distribution of the animals. In these descriptions all the technical terms appearing in the tables are explained. References to the principal authorities upon which the descriptions are based are given in footnotes, as are also references to important treatises and monographs which have appeared on the animals described. A knowledge of the historical basis of zoological names adds greatly to their significance and the author has consequently given a history of the nomenclature of each of the larger subdivisions of the animal kingdom in connection with the morphological description of it. A history of the general development of the system of classification since the publication of the tenth edition of Linnaeus' Systema Naturae and a brief survey of the progress of zoological studies in America are added in the Introduction.

Available in PDF, EPUB and Kindle. Book excerpt: The majority of undergraduate texts in invertebrate zoology (of which there are many) fall into one of two categories. They either offer a systematic treatment of groups of animals phylum by phylum, or adopt a functional approach to the various anatomical and physiological systems of the better known species. The Invertebrates is the first and only textbook to integrate both approaches and thus meet the modern teaching needs of the subject. This is the only invertebrate textbook to integrate systematics and functional approaches. The molecular systematics sections have been completely updated for the new edition. Strong evolutionary theme which reflects the importance of molecular techniques throughout. Distills the essential characteristics of each invertebrate group and lists diagnostic features to allow comparisons between phyla. New phyla have been added for the new edition. Stresses comparisons in physiology, reproduction and development. Improved layout and illustration quality. Second edition has sold 14000 copies. Nature of the first edition: 'Students will like this book. It deserves to succeed.'

Book excerpt: Excerpt from Guide to the Invertebrates of the Synoptic Collection: In the Museum of the Boston Society of Natural History It may be truly said that mankind is seeking as never before for a rational explanation of the origin and the development of animal life upon our earth. The more strenuous this search, the more imperative is the demand made upon naturalists to present in their museums, so far as possible, the most advanced knowledge concerning these problems. At the present time, therefore, it is not enough that a Synoptic Collection consist merely of specimens of animals effectively or artistically arranged. Neither is it sufficient that such a collection consist of species placed together by some arbitrary and artificial method.
