A calm water surface on any freshwater habitat can support a community of animals and plants of great interest. Some live above the water but in regular contact with it, and others hang down from the surface. This handbook deals with the smaller invertebrate animals of this surface community. Among these are springtails, pondskaters, water boatmen, water beetles and water spiders, as well as protozoa, rotifers and tiny crustaceans. After giving a brief introduction to the surface forces that are so important to these animals, the book describes the natural history of the main groups of animals in this community, drawing attention to topics on which further investigation is needed. Consideration is given to the problem of pollution by oil and by detergent. Keys are given for the identification of surface-dwelling animals, either to the major group or, where possible, to the species. Methods of keeping and studying the animals are described. 9781784275150/9781784275112 are digital reprints of 9780855462727/9780855462710 (1989).

Small Animal Ophthalmic Atlas and Guide is designed to offer a quick reference to common ocular conditions in dogs and cats, presenting high-quality color photographs to facilitate diagnosis and offering details on each condition to support clinicians in clinical decision making. In addition to updates throughout, the Second Edition includes significantly more images than the previous edition, with updates to images to include more representative examples where possible. In Small Animal Ophthalmic Atlas and Guide, the image section is organized by area of the eye, making it easy to find and compare images to make a diagnosis, and the disease section is carefully targeted to the most crucial details for developing a management plan. A companion website provides video clips. Written by a veterinary ophthalmologist working at a busy urban center, Small Animal Ophthalmic Atlas and Guide includes information on: Orbital disease, including inflammatory and neoplastic disease Eyelid and adnexal disease, such as abnormal hairs (distichiae, ectopic ciliae, and trichiasis), conformational abnormalities (entropion, ectropion, etc.), and third eyelid abnormalities such as gland prolapse Corneal and conjunctival disease, including tear film disorders, causes of keratoconjunctivitis, corneal ulceration, and feline surface ocular disease Anterior uveal conditions, covering uveal cysts, anterior uveitis, and anterior uveal neoplasia Lenticular disease, such as cataract and lens instability The posterior segment, covering normal fundic appearance, chorioretinitis, retinal degeneration, and retinal detachment Recognition and management of glaucoma With its broad coverage of essential topics and accessible images that help with accurate and fast diagnoses, Small Animal Ophthalmic Atlas and Guide is an essential reference for small animal general practitioners, students, residents, and interns, and can also be used as a reference to show examples to clients.
The Epidermis documents the proceedings of a symposium that explored in detail the fundamental aspects of the epidermis and the still poorly understood process of keratinization. The Division of Dermatology, University Extension and the School of Medicine of the University of California at Los Angeles agreed to sponsor the conference and offered the University's Residential Conference Center at Lake Arrowhead for the meeting place. This volume is a source book of basic dermatologic thought and information. More than a book of dermatology, this volume makes a singular contribution to our knowledge of keratinization. The volume contains 37 papers and opens with an introductory chapter on keratinization, focusing on the history of the keratohyalin granules, the role of lipids in the orderly keratinization of the epidermis, and the desquamation process. Subsequent chapters present studies on topics such as the behavior of the skin; the effects of various experimental conditions on keratinization in organ culture; and the localization and the regional variability in the concentration epidermal enzymes.
The new edition of this established textbook, now with full colour illustration, has been extensively revised and continues to provide a comprehensive, stimulating, readable and authoritative coverage of freshwater habitats, their communities and their functioning, the world over. The work will be of great value to undergraduate and graduate students, fellow researchers and water managers, and the plain language and lack of jargon should make it accessible to anyone interested in the functioning and current state of lakes and rivers. Having taught and researched over fifty years and six continents, Professor Brian Moss makes here extensive use of his personal experience as well as the huge literature now available on freshwaters. This is the fifth edition of his textbook, which, since the first edition in 1980, has steadily evolved to reflect a rapidly changing science and environment. It places increasing emphasis on the role of people in damaging and managing freshwaters as we move into the Anthropocene epoch and face unprecedented levels of climate and other changes, whilst rejoicing in the fascination of what are left of near pristine freshwater ecosystems. Professor Moss retired from the University of Liverpool following a career in Africa, the USA and the UK. He was awarded medals by the International Society for Limnology, of which he was President from 2007 to 2013, and The Institute of Ecology and Environmental Management. He was given The Ecology Institute's Excellence in Ecology Prize in 2009 and the book written for that prize, Liberation Ecology, was awarded the British Ecological Society's best ecology book prize in 2013.
The Novartis Foundation Series is a popular collection of the proceedings from Novartis Foundation Symposia, in which groups of leading scientists from a range of topics across biology, chemistry and medicine assembled to present papers and discuss results. The Novartis Foundation, originally known as the Ciba Foundation, is well known to scientists and clinicians around the world.
The oceans cover 70% of the Earth’s surface, and are critical components of Earth’s climate system. This new edition of Encyclopedia of Ocean Sciences, Six Volume Set summarizes the breadth of knowledge about them, providing revised, up to date entries as well coverage of new topics in the field. New and expanded sections include microbial ecology, high latitude systems and the cryosphere, climate and climate change, hydrothermal and cold seep systems. The structure of the work provides a modern presentation of the field, reflecting the input and different perspective of chemical, physical and biological oceanography, the specialized area of expertise of each of the three Editors-in-Chief. In this framework maximum attention has been devoted to making this an organic and unified reference. Represents a one-stop. organic information resource on the breadth of ocean science research Reflects the input and different perspective of chemical, physical and biological oceanography, the specialized area of expertise of each of the three Editors-in-Chief New and expanded sections include microbial ecology, high latitude systems and climate change Provides scientifically reliable information at a foundational level, making this work a resource for students as well as active researches
This textbook is primarily targeted towards students of veterinary-, animal- and agricultural sciences, but it is also well suited for university courses in general and mammalian physiology. The textbook emphasizes functional aspects of physiology. The book contains color illustrations, short, clarifying statements placed in the margin, questions, and clinical examples.
