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).

The information contained in this resource and activity book enhances children's knowledge and awareness of the living and non-living components of a pond, including the variety of life forms that can be found living on, under, and around the surface of a pond. Through observation and investigation, children will discover similarities, differences, and interactions among living things that inhabit a pond. Activities that emphasize plant and animal adaptations, interdependence, and food chains enable students to learn more about how living things survive in a still, freshwater ecosystem. Four transparencies (print books) or PowerPoint slides (eBooks) are included to engage students in discussion and reinforce the concepts presented in the book.

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.
