    Additional information
      The Laboratory Xenopus

    Sherril L. Green, Stanford University, Stanford, California, USA

    Even though Xenopus is one of the two most popular non-mammalian animals used in biomedical research, their value in the lab suffers from a lack of standardization regarding their optimal care, breeding, and housing.
    Filling the need for such a reference, The Laboratory Xenopus sp provides researchers and lab managers with a practical, step-by-step manual that emphasizes the humane care and use of captive clawed frogs in basic as well as biomedical, and toxicological research.

    The Only Book of Its Kind Available to Researchers
    · Amply illustrated with 50 color illustrations of management practices and technical procedures, this how-to guide:
    · Offers quick reference on the humane care and use of clawed frogs in the laboratory
    · Illustrates management practices and technical procedures with figures and tables
    · Provides sources of additional information on frogs, feed, and sanitation supplies
    · Supported with hypothesis-driven research, this well-organized manual explores the full range of responsibilities facing individuals who work with this species. The content is divided into intentionally brief sections that allow for the quick retrieval of essential information regarding important biological features and experimental methodology, as well as compliance and veterinary care, husbandry, housing, and water quality management.
