This book was released on 2017-08-03 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: THE CLASSIFICATION OF ANIMALS is Still Very much a field in which discovery and revision are continuing, even after two hundred years of study. The importance of classification in biology increases every year, because the experimental and practical fields find increasing need for accurate identification of animals and for understanding of comparative relationships. At least one outstanding biologist has opposed pubUcation of this new classification on the ground that it would be accepted as final, the classification, and would tend to make students think that all higher classification is finished. The intention of the compiler is just the opposite. Just as this classification is different in detail from all previous ones, so will future editions be still different, as we learn more about the comparative features of animals. It is anticipated that every new edition will spur students of the individual groups to propose improvements. It is therefore planned to issue corrected editions whenever appropriate. The very appearance of these subsequent editions will emphasize the growth of understanding of animal groups. Only one ostensibly complete classification of animals, living and fossil, has been published in recent years. That classification, by A. S. Pearse of Duke University, is a good one, based on the views of many specialists. Certain mechanical faults make it less usable than it should be, and the need for revision gave the original impetus to preparation of the present classification. Because Pearse did not usually indicate the source of his arrangements, he is not here cited as an authority. Nevertheless, the two classifications are basically very similar. No other single classification has been found that agrees so closely with the conclusions of the present study. It should be emphasized that, within certain limits, this classification is not a simple compilation of the views of specific workers. In nearly all details, choices have been made between conflicting schemes of various authors, not on the basis of the reputation of those authors but on my judgment of the soundness of their supporting arguments or on my analysis of the data they present. In none of the larger groups has the work of any single author been accepted without modification. Several considerations have influenced the decisions embodied in this classification. First, a false picture is given by a simplified classification, because the existing diversity is one of the principal features of the animal kingdom. Therefore, no groups should be combined merely for the sake of simplicity. Second, although the previous item would seem to require coverage of the groupings at all possible levels, to show the extreme range of division and subdivision, this is not in fact possible. Not only are there many conflicting groupings at certain levels, such as of phyla or orders, but there is no practical way to show these groupings in a general classification. It is a compromise that is believed to be effective to subdivide the phyla only into classes, subclasses, and orders. Other possible groupings, such as subphyla and superorders are referred to in the notes. Third, two groups which are so distinct at any level that they cannot be described in common terms must be separated at that level. (For example, Pterobranchia and Enteropneusta; see the Notes on the Taxa.) Fourth, groups which cannot be distinguished at any particular level by the type of characters used for their neighbors must be combined at that level. (For example, the sometime classes of Nematoda...

Download or read book The Mycetozoans written by Lindsay Olive and published by Elsevier. This book was released on 2012-12-02 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mycetozoans brings together, for the first time in a single volume, comprehensive information on the biology and classification of the mycetozoans and associated groups. The mycetozoans and their associates remain of prime interest to taxonomists and phylogenists because major new taxa continue to be discovered among them. This book informs the reader where to find mycetozoans, how to isolate and culture them, their life cycles and ultrastructure, and some of the experiments that may be performed with them. It presents studies on Protostelia (protostelids); Dictyostelia (dictyostelid cellular slime molds); Myxogastria (myxomycetes); Acrasea (acrasid cellular slime molds); Plasmodiophorina (plasmodiophorids); and Labyrinthulas (labyrinthulina and thraustochytrids). This text can serve as a reference tool in courses on mycetozoans, protozoology, mycology, and developmental biology of lower organisms, and as a concentrated source of information for research workers in all aspects of the biology and taxonomy of these organisms.

Download or read book Syllabus of Plant Families written by Adolf Engler and published by . This book was released on 2012 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Part 1/1 of Engler's Syllabus of Plant Families - Blue-green Algae, Myxomycetes and Myxomycete-like organisms, Phytoparasitic protists, Heterotrophic Hetero -kontobionta and Fungi p.p. provides a thorough treatment of the world-wide morphological and molecular diversity of the Cyanoprokaryota, Acrasia and Eumycetozoa, Phytomyxea, the heterotrophic Heterokontobionta (Labyrinthulomycota, Oomycota), and the lower fungi (Chytridiomycota, Zygomycota and Glomeromycota). Recent DNA sequence data and advances in phylogenetic analysis brought tremendous changes to the interpretation of evolutionary relationships in every taxonomic rank, even in these lowermost plant groups, although their origin is still highly disputed. The authors followed the tradition of A. Engler with morphological-anatomical data, but are additionally incorporating the latest results from molecular phylogenies. This up-to-date overview of the Cyanoprokaryota, Acrasia, Eumycetozoa, Phytomyxea, Labyrinthulomycota, Oomycota, Chytridiomycota, Zygomycota and Glomeromycota will be a useful reference for a long time to come. Engler's Syllabus of Plant Families has since its first publication in 1887 aimed to provide both the researcher, and particularly the student with a concise survey of the plant kingdom as a whole, presenting all higher systematic units right down to families and genera of plants and fungi. In 1964, more than 45 years ago, the 12th edition of the well-known "Syllabus der Pflanzenfamilien" ("Syllabus of Plant Families"), set a standard. Now, the completely restructured and revised 13th edition of Engler's Syllabus published in 5 parts and in English language for the first time also considers molecular data, which have only recently become available in order to provide an up-to-date evolutionary and systematic overview of the plant groups treated. In our "molecular times" there is a vitally important and growing need to preserve the knowledge of the entire range of diversity and biology of organisms for coming generations, as there is a decline in "classical" morphological and taxonomical expertise, especially for less popular (showy) groups of organisms. Accordingly, the 13th edition of Syllabus of Plant Families synthesizes both modern data and classical expertise, serving to educate future experts who will maintain our knowledge of the full range of Earth's biodiversity. Syllabus of Plant Families is a mandatory reference for students, experts and researchers from all fields of biological sciences, particularly botany.

Available in PDF, EPUB and Kindle. Book excerpt: Animals do have culture, maintains this delightfully illustrated and provocative book, which cites a number of fascinating instances of animal communication and learning. John Bonner traces the origins of culture back to the early biological evolution of animals and provides examples of five categories of behavior leading to nonhuman culture: physical dexterity, relations with other species, auditory communication within a species, geographic locations, and inventions or innovations. Defining culture as the transmission of information by behavioral rather than genetical means, he demonstrates the continuum between the traits we find in animals and those we often consider uniquely human.

Download or read book The Ideas of Biology written by John Tyler Bonner and published by Courier Corporation. This book was released on 2002-01-01 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The great achievement of this book," observed the distinguished science writer Gerald Wendt, "is that it presents the basic concepts of biology in concise, lucid, orderly form and thus gradually and understandably transforms the miracle of life into a succession of miraculously simple processes." John Tyler Bonner's series of concise essays explores the foundations of modern biology: the cell, genetics, development, and evolution. "Biologists are fortunate in having such a scientist and author interpret these facts, for Dr. Bonner's style of writing contributes greatly to the success of the work," noted Library Journal, adding, "The drawings which accompany the text are excellent." Since evolution provides the framework for life, the author makes it his central theme, with introductory material on the living machine itself and succeeding chapters on heredity, embryonic development, and ultimately, relations between organisms and their environment. Written as a supplement to classroom biology texts, this volume can be read independently.

Download or read book Systematics and Evolution written by David McLaughlin and published by Springer Science & Business Media. This book was released on 2000-09-22 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mycology, the study of fungi, originated as a subdiscipline of botany and was a des criptive discipline, largely neglected as an experimental science until the early years of this century. A seminal paper by Blakeslee in 1904 provided evidence for self incompatibility, termed "heterothallism", and stimulated interest in studies related to the control of sexual reproduction in fungi by mating-type specificities. Soon to follow was the demonstration that sexually reproducing fungi exhibit Mendelian inheritance and that it was possible to conduct formal genetic analysis with fungi. The names Burgetf, Kniep and Lindegren are all associated with this early period of fungal genet ics research. These studies and the discovery of penicillin by Fleming, who shared a Nobel Prize in 1945, provided further impetus for experimental research with fungi. Thus began a period of interest in mutation induction and analysis of mutants for biochemical traits. Such fundamental research, conducted largely with Neurospora crassa, led to the one gene: one enzyme hypothesis and to a second Nobel Prize for fungal research awarded to Beadle and Tatum in 1958. Fundamental research in biochemical genetics was extended to other fungi, especially to Saccharomyces cerevisiae, and by the mid-1960s fungal systems were much favored for studies in eukaryotic molecular biology and were soon able to compete with bacterial systems in the molecular arena.
