This book has arisen from the Second European Meeting on Bacterial Genetics and Ecology (Bageco-2) held at the University of Wales, College of Cardiff which we organised on 11-12 April 1989. The meeting was attended by some 60 participants from eight European countries and was made possible by partial financial support from the Commission of the European Communities (CEC) and Imperial Chem ical Industries (UK) Ltd. The meeting was organised to discuss modern developments in the genetics of bacteria in aquatic and terrestrial habitats. It followed on from, and complemented, the first meeting of this series organised by Jean-Pierre Gratia in Brussels during April 1987 which concentrated more on medical and epidemiological issues. ! The next meeting will be organised by Michel J. Gauthier in 1991 at Nice, France. If you have been fired with enthusiasm for ecological bacterial genetics after having read this book, and want to attend the next meeting but did not hear about the one in Cardiff, you should write to Dr Gauthier to be put on the address list. A lot is now known about bacterial genetics at the physiological, biochemical and molecular level, and bacterial ecology has developed rapidly over the last 20 years. However, until very recently, few researchers have crossed the divide and linked these two specialisms.
This text attempts to introduce the molecular biology of cell membranes to students and professionals of diverse backgrounds. Although several membrane biology books are available, they do not integrate recent knowledge gained using modern molecular tools with more traditional membrane topics. Molecular techniques, such as cDNA cloning and x-ray diffraction, have provided fresh insights into cell membrane structure and function. The great excitement today, which I attempt to convey in this book, is that molecular details are beginning to merge with physiological responses. In other words, we are beginning to understand precisely how membranes work. This textbook is appropriate for upper-level undergraduate or beginning graduate students. Readers should have previous or concurrent coursework in biochemistry; prior studies in elementary physiology would be helpful. I have found that the presentation of topics in this book is appropriate for students of biology, biochemistry, biophysics and physiology, chemistry, and medicine. This book will be useful in courses focusing on membranes and as a supplementary text in biochemistry courses. Professionals will also find this to be a useful resource book for their personal libraries.
Also available as a Time Warner AudioBook "Lost in awe at the beauty around me, I must have slipped into a state of heightened awareness....Self was utterly absent: I and the chimpanzees, the earth and trees and air, seemed to merge, to become one with the spirit power of life itself." Her revolutionary studies of Tanzania's chimpanzees forever altered our definition of "humanity." Now, intriguing as always, Jane Goodall explores her deepest convictions in a heartfelt memoir that takes her from the London Blitz to Louis Leakey's famous excavations in Africa and then into the forest of Gombe. From the unforgettable moment when a wild chimpanzee gently grasps her hand to the terror of a hostage-taking and the sorrow of her husband's death, her unshakable spiritual beliefs break through to give her life meaning and direction. Here, thoughtfully exploring the challenges of both science and the soul, she offers an inspiring, optimistic message as profound as the knowledge she brought back from the forests, and that gives us all... An Alternate Selection of Book-of-the-Month Club® and of One Spirit® The PBS special Jane Goodall: Reason for Hope was inspired by this book.
Entomopathogenic bacteria (Bacillus thuringiensis and B. sphaericus) are increasingly used as biopesticides to control larval insect populations which are either agricultural or forestry pests and to reduce those which as adults are vectors of severe human diseases. This new book, the first since 1993 to address all aspects of entomopathogenic bacteria, provides undergraduate and graduate students as well as research scientists with a complete, modern view of this important group of bacteria. The authors, chosen for their sustained contributions to the field, cover both fundamental and applied research in this area. The main topics include bacterial ecology and taxonomy, toxin diversity, activity and mode of action, regulation and environment of the genes, safety and ecotoxicology, production and field application of the bacteria, and outbreaks of resistant populations. The book concludes with the most recent data obtained on transgenic biotechnology and addresses environmental impact issues.
Clonal animals, that is those that are genetically identical, are of great importance in biology. The supposed evolutionary advantages of sexual versus asexual reproduction are one of the central paradoxes of current evolutionary theory. The evolved strategy of asexual reproduction includes a large number of diverse species in many different groups, for example aphids, guppies, planktonic rotifers and others. This book draws together many aspects of the functional biology of clonal animals, from their taxonomy and feeding ecology to their life-histories and evolutionary biology. The mechanism of somatic division and parthenogenesis and the benefits of cloning to a variety of Metazoa are examined. Together with a consideration of obligate cloning and modular organisms, this book should be a valuable reference for biologists with an interest in genetics, ecology and evolutionary biology.
This book discusses the history of invertebrate fossil understanding and classification by exploring fossil studies between the 15th and 18th centuries. Before the modern age, the understanding of fossil findings went through several phases. The treatment by philologists, philosophers and historians of natural sciences involved religious, sometimes folkloristic, aspects before scientific ones. This work showcases and assesses these original findings by carrying out a bibliographical, and above all iconographical research, aimed at finding the first printed images of the objects that we now know as fossils. From here, the authors provide an understanding of the true nature of fossils by analyzing them through modern academic viewpoints, and describing each fossil group from a paleontological and taxonomic point of view, retracing their treatment in the course of the centuries. As a point of reference for each fossil group treated, the authors have considered indispensable the use of ancient prints as evidence of the first iconographic sources dedicated to fossils, starting from those in the late fifteenth century, dedicated to the most common groups of invertebrates without neglecting a necessary exception, the ichthyodontolites, fundamental in the discussion in Italy on the interpretation of the organic origin of fossils, and from the end of the sixteenth century to about half of the eighteenth century. The abundant iconographic apparatus used, often unpublished or specially reworked, is essential and functional to the understanding of the various aspects addressed, a visual complement to the text and vice versa, designed and used taking its cue from the need imposed on early scholars to document their discoveries visually. Among the chosen images there is no shortage of original attributions to fossil finds that have been poorly understood or misidentified until now. The English translation of this book from its Italian original manuscript was done with the help of artificial intelligence (machine translation by the service provider DeepL.com). A subsequent human revision of the content was done by the authors.
In recent years, parasitologists have learned much about the way in which parasite biochemistry differs from that of free-living organisms. Inside the host, factors such as temperature, oxygen tension, carbon dioxide concentration and pH have important consequences for the biochemistry and physiology of the parasitic organism. Strong selection pressure therefore operates at all stages of a parasite's life cycle. The parasite's adaptational response to this pressure is the subject of this book. Under the headings "The nature of parasite adaptation", "Energy metabolism", "Digestion and uptake of nutrients", "Host immunity and parasite adaptation", "Biochemical adaptation and the magic bullet" and "Biochemical variation in parasites", present knowledge of parasite metabolism and how it reflects adaptation to particular environments is surveyed. The ways in which these adaptations may have developed during their evolution - with reference to the modern evolution of strain variations and the development of resistance to antiparasitic compounds - are explored, together with immunological aspects of the host-parasite relationship and potential metabolic targets for chemotherapy. This book should be of use to all those involved and interested in the biochemistry of parasites and its relation to their evolution, ecology, adaptation and variation. Those aspects of parasite metabolism that are attacked by anti-parasitic drugs are described, making this a useful book for those involved in the pharmaceutical industry. This book should be of interest to parasitologists and comparative biochemists.

The present book is a monograph about two groups of hypotrichous ciliates, namely the Amphisiellidae and the Trachelostylidae. It is the third of six volumes which - view the Hypotricha, one of the three major taxa of the spirotrichs. The first volume is about the Oxytrichidae, a rather large group, many species of which have 18 highly characteristically arranged frontal-ventral-transverse cirri and, much more importantly, a comparatively complex dorsal ciliature due to (oxytrichid) fragmen- tion of dorsal kineties during cell division (Berger 1999). The second volume deals with the Urostyloidea, which are characterised by a zigzag-arrangement of the ventral cirri (Berger 2006). Although this pattern is often very impressive, it is a relatively simple feature originating by a more or less distinct increase of the number of frontal-ventral-transverse cirri anlagen. These anlagen produce cirral pairs which are serially arranged in non-dividing specimens. Some - ers are likely astonished that the monograph on urostyloids does not include Urol- tus, a group of tailed species, which also have a distinct zigzagging cirral pattern. However, morphological and molecular data indicate that the zigzag pattern of U- leptus evolved independently, that is, convergently to that of the urostyloids. Thus, Uroleptus was excluded from the urostyloid review. A zigzag pattern is also known from some oxytrichids, for example, Neokeronopsis, Territricha, Pattersoniella, showing that this pattern evolved several times independently (Berger 1999, 2006, Foissner et al. 2004).
The Anthropocene is the "age of human influence", an epoch well known for its urban impact. More than half of all people already live in cities, and this proportion is expected to rise to almost 70 percent by 2050. Like other species in urban areas, bats must contend with the pressures of profound and irreversible land cover change and overcome certain unique challenges, such as the high density of roads, lights, glass, and free-ranging domestic animals. Research on urban bats in recent decades indicates that when it comes to urban life, some bats are synanthropes. In other words, although most species of bats are negatively impacted by urbanisation, many appear to not only succeed, but also thrive in cities and towns. This observation has inspired interesting questions about bats in relation to urbanisation. Which traits and behaviours equip bats for urban success? What features of urban areas increase the likelihood that bats will successfully persist there or even colonize new areas? And how does the success of urban bats affect co-habiting humans? Our book explores the interactions between bats and urban environments through case studies and reviews. Understanding how different species interact with urban environments can reveal potential opportunities to mitigate urban threats to bats and threats posed by bats to other urban organisms, including humans. With this book, we thus aspire to provide a knowledge base to help guide current and future efforts to conserve bats.
Volumes 11 to 20 in a 29-volume set which contain all Charles Darwin's published works. Darwin was one of the most influential figures of the 19th century whose work remains a central subject of study in the history of ideas, the history of science, zoology, botany, geology and evolution.
An interdisciplinary challenge to assumptions about animals and animality deeply embedded in our own ways of thought, exposing sensitive and largely unexplored aspects of the understanding of our common humanity.
Caterpillars are excellent model organisms for understanding how multiple selective forces shape the ecology and evolution of insects, and organisms in general. Recent research using the tools of modern molecular biology, genetics, metabolomics, microbial ecology, experiments conducted at a global level, network analysis, and statistical analyses of global data sets, combined with basic natural history, are yielding exciting new insights into caterpillar adaptations and ecology. The best way to view these research advances is within a framework of tri-trophic interactions. This is a timely topic for research given the central role of caterpillars and plants in the ecology and trophic structure of terrestrial communities. This book is unique in that it contains chapters from a team of experts on a diversity of key topics within caterpillar-plant interactions. This volume brings together contributions by researchers from around the globe, working in both tropical and temperate habitats, and in human-managed and more natural habitats. It is a significant contribution to our understanding of insect biology, and the role that insects, as represented by caterpillars, play in a world increasingly dominated by humans and one in which threats to insect biodiversity are mounting.

Ever since the discovery of fossil remains of extinct animals associated with flint implements, bones and other animal remains have been providing invaluable information to the archaeologist. In the last 20 years many archaeologists and zoologists have taken to studying such "archaeofaunal" remains, and the science of "zoo-archaeology" has come into being. What was the nature of the environment in which our ancestors lived? In which season were sites occupied? When did our earliest ancestors start to hunt big game, and how efficient were they as hunters? Were early humans responsible for the extinction of so many species of large mammals 10-20,000 years ago? When, where and why were certain animals first domesticated? When did milking and horse-riding begin? Did the Romans influence our eating habits? What were sanitary conditions like in medieval England? And could the terrible pestilence which afflicted the English in the seventh century AD have been plague? These are some of the questions dealt with in this book. The book also describes the nature and development of bones and teeth, and some of the methods used in zoo-archaeology.
Receptor specific antibodies are excellent probes for a wide range of biological investigations on receptor structure and function. The hybridoma technology (Kohler and Milstein, 1975) has inevitably had a major impact on this field with most of the better known receptors now identified with monoclonal antibodies. This volume of the Receptors and Recognition series provides reviews of recent developments in this field and emphasizes in particular the new opportunities afforded by the judicious application of monoclonal reagents. It is assumed that most readers will be familiar with the now fairly routine methods of cell fusion, hybridoma cloning and selection for producing monoclonal antibodies and so few details of the basic technical procedures are described. Several good reviews on this topic are however available (see Galfre and Milstein, 1981; Goding, 1980; Yelton and Scharf, 1981; McMichael and Fabre, 1982). By no means all vertebrate receptor species are discussed here; omissions include antibodies to low density lipoprotein receptors (Beisiegel et al. , 1981; Kita et al. , 1981), prolactin and growth hormone receptors (Friesen etal. , 1982; Simpson et al. , 1983) and the hepatocyte asialoglycoprotein receptor (Schwartz et al. , 1981; Harford et al. , 1982). Nevertheless the coverage is comprehensive and critical and the individual chapters provided illustrate vividly the rapid progress being made.
Galapagos Giant Tortoises brings together researchers and conservationists to share the most up-to-date knowledge of Galapagos giant tortoises. Despite being icons of the world-famous Galapagos Archipelago and the target of more than 50 years of conservation research and management, Galapagos giant tortoise evolution and much of their ecology remained unknown until recently. This book documents the history, the pressing conservation issues, and success stories recovering several of the 15 different species of Galapagos tortoises from near extinction. The book begins with an overview of the history of the relationship between humans and Galapagos giant tortoises, starting from initial heavy exploitation of tortoises by pirates and whalers, and extending to the start of the modern conservation era in the 1960s. The book then shifts to biology, describing Galapagos tortoise evolution, taxonomy, ecology, habitats, reproduction, and behavior. Next the decades of conservation efforts and their results are reviewed, including issues of captive breeding, invasive species, introduced diseases, and de-extinction, as well as the current status and distribution of every species. The final portion of the book turns to four case studies of restoration, and then looks ahead to the future of all tortoise populations.The latest volume in the Biodiversity of the World: Conservation from Genes to Landscape series, Galapagos Giant Tortoises is a valuable resource for researchers and conservationists, as well as students of biology, wildlife conservation, and herpetology.
