This book was released on 2019-12-20 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evolution and Classification of the Pocket Gophers of the Subfamily Geomyinae by Robert J. Russell is an informational record of the taxonomy of a new species of gopher. Excerpt: "Morphological features of the fossils and their stratigraphic provenience provide the information upon which phylogenetic interpretations are based. Although the most critical sequences of the fossil record are lacking, and although the existing fossils are mostly fragmentary and therefore seldom furnish ideally suitable data for the interpretations that have been made, phylogenetic conclusions drawn from fossil materials are superior to those drawn on other bases. The especially relevant characters are those disclosing primary trends in the evolution of the modern assemblages."

Download or read book The Biology of the Naked Mole Rat written by Paul W. Sherman and published by Princeton University Press. This book was released on 2017-03-14 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume brings together more than a decade of information collected in the field and lab on the naked mole-rat (Heterocephalus glaber), a northeast African mammal unique for its physical characteristics and eusociality. Nearly blind and virtually hairless, naked mole-rats inhabit large subterranean colonies in which only one female and her one to three mates conceive offspring, while the young from previous litters maintain and defend the group as do workers in colonies of the social insects. In this first major treatise on naked mole-rats an international group of researchers covers such topics as the evolution of eusociality, phylogeny and systematics of the rodent family Bathyergidae, population and behavioral ecology and genetics of naked mole-rats in the field, vocal and nonvocal behaviors, social organization and divisions of labor within colonies, and climatic, social, and physiological factors affecting growth, reproduction, and reproductive suppression.

Download or read book The Stockholm Paradigm written by Daniel R. Brooks and published by University of Chicago Press. This book was released on 2019-07-19 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: The contemporary crisis of emerging disease has been a century and a half in the making. Human, veterinary, and crop health practitioners convinced themselves that disease could be controlled by medicating the sick, vaccinating those at risk, and eradicating the parts of the biosphere responsible for disease transmission. Evolutionary biologists assured themselves that coevolution between pathogens and hosts provided a firewall against disease emergence in new hosts. Most climate scientists made no connection between climate changes and disease. None of these traditional perspectives anticipated the onslaught of emerging infectious diseases confronting humanity today. As this book reveals, a new understanding of the evolution of pathogen-host systems, called the Stockholm Paradigm, explains what is happening. The planet is a minefield of pathogens with preexisting capacities to infect susceptible but unexposed hosts, needing only the opportunity for contact. Climate change has always been the major catalyst for such new opportunities, because it disrupts local ecosystem structure and allows pathogens and hosts to move. Once pathogens expand to new hosts, novel variants may emerge, each with new infection capacities. Mathematical models and real-world examples uniformly support these ideas. Emerging disease is thus one of the greatest climate change–related threats confronting humanity. Even without deadly global catastrophes on the scale of the 1918 Spanish Influenza pandemic, emerging diseases cost humanity more than a trillion dollars per year in treatment and lost productivity. But while time is short, the danger is great, and we are largely unprepared, the Stockholm Paradigm offers hope for managing the crisis. By using the DAMA (document, assess, monitor, act) protocol, we can “anticipate to mitigate” emerging disease, buying time and saving money while we search for more effective ways to cope with this challenge.

Download or read book Marine Parasitology written by Klaus Rohde and published by CSIRO PUBLISHING. This book was released on 2005-09-13 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive, authoritative and up-to-date work provides the definitive overview of marine parasites worldwide. It is an invaluable reference for students and researchers in parasitology and marine biology and will also be of interest to ecologists, aquaculturists and invertebrate biologists. Initial chapters review the diversity and basic biology of the different groups of marine parasites, discussing their morphology, life cycles, infection mechanisms and effects on hosts. The ecology and importance of marine parasites are discussed in the second part of the book, where contributions investigate behavioural and ecological aspects of parasitism and discuss the evolution and zoogeography of marine parasites. In addition, the economic, environmental and medical significance of these organisms is outlined, particularly their importance in aquaculture and their effects on marine mammals and birds. Written by an international team of contributors, the emphasis is on a thorough grounding in marine parasitology combined with reviews of novel concepts and cutting-edge research.
Download or read book Orthodontic Diagnosis written by Thomas Rakosi and published by Thieme. This book was released on 1993 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: An illustrated guide for the complex process of orthodontic diagnostics and indication. The total process of treatment planning including the scientific bases is pictorially described. Beside the conventional methods of examination and model analysis, emphasis is placed on the cranio-facial growth processes, the aetiology of malocclusions and on the importance of functional analysis. The following three aspects are described in detail in this book: Growth of the Facial Skeleton - types of treatment which promote or guide growth. In order to control these natural processes artificially, a precise understanding of them is required. Aetiology of the Malocclusion - the various types of causative therapy and the elimination of the causes. Functional Analysis - many malocclusions are a result of dysfunctions. As a variety of methods are available for treating dysfunctions, functional analysis is taken very seriously.

Download or read book Advances in Stromatolite Geobiology written by Joachim Reitner and published by Springer Science & Business Media. This book was released on 2010-10-22 with total page 553 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stromatolites are the most intriguing geobiological structures of the entire earth history since the beginning of the fossil record in the Archaean. Stromatolites and microbialites are interpreted as biosedimentological remains of biofilms and microbial mats. These structures are important environmental and evolutionary archives which give us information about ancient habitats, biodiversity, and evolution of complex benthic ecosystems. However, many geobiological aspects of these structures are still unknown or only poorly understood. The present proceedings highlight the new ideas and information on the formation and environmental setting of stromatolites presented at the occasion of the Kalkowsky Symposium 2008, held in Göttingen, Germany.
