Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Opalinid Ciliate Infusorians Since the summer of 1908 the author has been collecting and Ob serving living specimens of American and West Indian Opalinidae and preserved material from all parts of the world. During this period he has been much indebted to many persons for assistance and courtesies in connection with these studies. The Marine Biological Station at Naples preserved and sent intestines of the Mediterranean fish Box boom, containing Protoopalina saturnalis In fine condition. Prof. E. A. Andrews, Of Johns Hopkins University, sent me im portant material (adult Bufo marinus and its tadpoles, from Jamaica, and tadpoles from an undetermined Anuran from Bromelia leaf cups in Jamaica). H. H. And C. S. Brimley, of Raleigh, North caroa lina, collected for me Anura and Urodela. Dr. H. C. Fortner, of the University of Tennessee, sent me Opalinas from Michigan. Prof. E. L. Mark, director Of the Bermuda Biological Laboratory, has obtained for me, through his pupil, Mr. C. S. Simkins, important data as to the breeding habits of Bufo marinus in Bermuda, and Dr. Leonhard Stejneger has repeatedly given me assistance in matters Of taxonomy of the Amphibia, reviewing my list of names of the forms studied, bringing the nomenclature into harmony with that adopted at the United States National Museum. He has also given considerable zoogeographic data. Professor Hegner kindly sent me an excellent slide Of a form collected by Dr. C. E. Simon, which, by permission, I am describing under the tentative name Opalina [zaruarum]. With this slide was sent a manuscript copy of a paper (hegner and hsiang-fong Wu, 1921) upon this Opalina. I wish very cordially to thank these authors and Doctor Simon. Several institutions have generously extended to me their hos pitality during periods of work ranging from two weeks to eight months. For this kindness I wish to express my most cordial thanks to the Scripps Institution of Biology and its director, Prof. William E. Ritter; to the University of California and the director Of its zoological department, Prof. C. A. Kofoid; to the University Of Washington, and to Prof. Trevor Kincaid, director of the Puget Sound Biological Laboratory; to the authorities of the United States National Museum, and especially to Dr. Leonhard Stejneger, curator of vertebrates in this museum; and to Johns Hopkins University and members Of the faculty of its department of zoology, Profs.

Download or read book A Functional Biology of Parasitism written by G.W. Esch and published by Springer Science & Business Media. This book was released on 2013-03-07 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Ecology and Biogeography in Sri Lanka written by C.H. Fernando and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: When the late Professor Joachim Illies suggested in 1980 that I edit a volume of the Monographiae Biologicae on Sri Lanka, I was glad to accept the challenge. Although I had spent only six years of my research and teaching career in Sri Lanka, I had made personal contact or corresponded with many scientists who had worked in, still work in, or who have studied material from Sri Lanka. The present domicile of the authors of the chapters in this volume shows the wide geographic spread of interest in Sri Lanka, and indicates also the dispersion of Sri Lankan scientists like myself. Sri Lanka has had a relatively long history of indigenous scientific research in the natural sciences. From the early work of Kelaart (1852, Prodromous Fauna Zeylanicae, Ceylon Govt. Press, 250 pp.) to the present time, there has been a more or less sustained research effort in the natural sciences. The Colombo Museum, which celebrated its centenary only a few years ago, and the world famous Peradeniya Botanical Gardens, served as repositories and bases for continued research on the fauna and flora. There are a number of land marks in these studies.
Download or read book The Ciliated Protozoa written by John O. Corliss and published by Elsevier. This book was released on 2016-04-20 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ciliated Protozoa: Characterization, Classification and Guide to the Literature, Second Edition presents a premature major overhauling of the systematics of the Ciliophora sensu lato, which is considered a separate phylum. This book includes a developed rationale and defined criteria that serve as a basis for the reclassification of the ciliates. Discussions of controversial taxa are provided, including arbitrary but critical resolution of their place in, or rejection from, the new overall system. The ideas concerning the evolution of ciliates, as well as "phylogenetic trees are also covered in this text. This text categorizes the ciliates into three classes—Kinetofragminophora, Oligohymenophora, and Polyhymenophora. This publication is a good source for biologists and students interested in ciliates.
Download or read book Blastocystis Pathogen or Passenger written by Heinz Mehlhorn and published by Springer Science & Business Media. This book was released on 2012-12-13 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: The stages of Blastocystis have been known for 101 years. However, many facts are still disputed, e.g. even the question whether it is a true pathogen or a commensal present in sometimes life-threatening diarrheas. The present book evaluates in chapters contributed by renowned researchers the latest findings on: •Landmarks in the discovery of Blastocystis •Epidemiology, transmission and zoonotic potential •Morphology of human and animal Blastocystis isolates •Clinical aspects of Blastocystis infections •Behavioral decision analysis: what makes us sick? •Blastocystis-host interactions •Molecular approaches on the systematical position •Genetic polymorphism •Blastocystis from a statistical point of view •Diarrheas due to different agents of disease •Zoonotic diseases in comparison As such, this book provides a broad range of information for people working in this field, for physicians and veterinarians who are confronted with clinical cases, teachers, students and technical staff members in the fields of microbiology, parasitology and diagnostic methods.

Download or read book Paramecium written by Geoffrey Beale and published by CRC Press. This book was released on 2008-03-27 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The techniques used to decipher the genetic makeup of species as well as epigenetic mechanisms are essential for explaining life forms and studying their DNA. As a eukaryotic model, Paramecium is well suited for genetic analysis. Taking a rather unconventional view of genetics, Paramecium: Genetics and Epigenetics explores how to use this protozoan as a basis for studying complex cells. The book discusses various aspects of Paramecium, including the cortex, the cytoplasm, nuclei, asexual fission, conjugation, autogamy,macronuclear regeneration, cytogamy, life cycle phases, and behavior. It examines the assorted mating types of the genus and how these mating types are determined. It also elucidates some techniques that identify genetically defined genes with the DNA from a library that comprises those genes and details the genetic, epigenetic, chemical, and molecular facets of several different traits. In addition, the authors chronicle the history and reemergence of investigating RNA and DNA in Paramecium. With many powerful tools now available, Paramecium research is entering a new frontier in molecular biology. A full account of Paramecium genetics, this book presents a wealth of time-consuming observations and remarkable phenomena that will lead to a better understanding of complex cells.

Download or read book Ciliates written by Klaus Hausmann and published by VCH Publishers. This book was released on 1996 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: As new hypotheses to explain biological processes are formulated and new techniques are perfected, the ubiquitous presence of ciliates and their ease of cultivation have won new converts from genetics, cell biology, ecology, molecular biology, and other specialists who are searching for a convenient organism to test their hypotheses and techniques. For these scientists as well as general biologists, graduate students beginning their careers, and those protozoologists already charmed by ciliates, this compilation of the current state of knowledge of ciliates will be exciting reading. Modern ultrastructural and molecular techniques offer insights on cytology, metabolism, and genetics of ciliates that have stimulated new conclusions about ontogenesis, sexuality, ecology, and systematics.
