Description : This book is useful for anyone interested in the basic structural and functional characteristics of the digestive system and how these vary among vertebrate groups and species. It discusses all of the major aspects of nutrition, anatomy and physiology in all of the major groups of vertebrates. It contains numerous figures and tables to aid in their comparison, including many illustrations of gastrointestinal tracts of vertebrates prepared so as to allow for direct comparison. The terminology of scientific specialties and sub-specialties is defined and animals are referred to by both their common and scientific names. Relationships between digestive strategies and the diet and environment are discussed throughout the text, and brought together in a chapter on the evolution of the digestive system. The final chapter offers a brief summary of the major concepts and suggests future directions for research.

Description : This volume of the series Handbook of Zoology deals with the anatomy of the gastrointestinal digestive tract – stomach, small intestine, caecum and colon – in all eutherian orders and suborders. It presents compilations of anatomical studies, as well as an extensive list of references, which makes widely dispersed literature accessible. Introductory sections to orders and suborders give notice to biology, taxonomy, biogeography and food of the respective taxon. It is a characteristic of this book that different sections of the post-oesophageal tract are discussed separately from each other. Informations on form and function of organs of digestion in eutherians are discussed under comparative-anatomical aspects. The variability and diversity of anatomical structures represents the basis of functional differentiations.

Description : Building on the success of its popular predecessor, the second edition of Ecotoxicology of Amphibians and Reptiles presents newly available findings on the species that are important environmental indicators. This new edition covers nearly twice as many topics as the first, including recent developments in the ecotoxicology of amphibians and reptiles, the current status of these animals, and intrinsic factors that affect their susceptibility to contaminants. The book also provides the latest information on specific groups of contaminants and their effects and body burdens in herpetafauna. After a review of how contaminants interact with other ecological factors, the text explores concerns for the future. New in the second edition: New research on the effects of pesticides, heavy metals, endocrine disrupting chemicals, and UVB Increased focus on the effects of contaminants rather than merely reporting residue information A synthesis of information on atrazine and its effects on gonads at low concentrations Coverage of the potentially alarming new cadre of chemicals that have recently or are about to come on the market for which there is very little or no information Important advances in surveying and monitoring One of the major factors behind the writing of the first edition was the worldwide phenomenon of declining amphibian populations. Although this decline has not abated, the breadth of research into its causes has expanded significantly. With chapter contributors carefully selected by the team of editors as leaders in their fields, this book provides an authoritative compendium of the most recent information on effects and residues coupled with a syntheses of what these numbers mean to science and policy.

Description : Biology and Diseases of the Ferret, Third Edition hasbeen thoroughly revised and updated to provide a current,comprehensive reference on the ferret. Encyclopedic in scope, it isthe only book to focus on the characteristics that make the ferretan important research animal, with detailed information onconditions, procedures, and treatments. Offering basic informationon biology, husbandry, clinical medicine, and surgery, as well asunique information on the use of ferrets in biomedical research,Biology and Diseases of the Ferret is an essential resourcefor investigators using ferrets in the laboratory and for companionanimal and comparative medicine veterinarians. The Third Edition adds ten completely new chapters, coveringregulatory considerations, black-footed ferret recovery, diseasesof the cardiovascular system, viral respiratory disease research,morbillivirus research, genetic engineering, hearing and auditoryfunction, vision and neuroplasticity research, nausea and vomitingresearch, and lung carcinogenesis research. Additionally, theanesthesia, surgery, and biomethodology chapter has been subdividedinto three and thoroughly expanded. The book also highlights theferret genome project, along with the emerging technology ofgenetically engineered ferrets, which is of particular importanceto the future of the ferret as an animal model in research and willallow the investigation of diseases and their genetic basis in asmall, easily maintained, non-rodent species.

Description : 1. 1 Scientific Aims In recent years, there has been a definite trend away from the casuistic scientific thinking which has dominated the scientific world, at least in the field of medicobi ological research. Now, in the last decade of this century, scientists are returning to a conceptual way of thinking that characterized the beginning of this century, namely organismal thinking. The holistic concept is not a new one; it was rekindled by a small group of scientists who, in the previous two decades, have begun to warn against too great an emphasis being placed on a molecular casuistic approach as the final pursuit to science (see Duncker 1983). These thinkers were perhaps instrumental in helping to turn the tide, to instruct and encourage fellow researchers to extend their findings from the molecular and to the organismal (see Duncker 1983, 1992a,b; Duncker and Kreite 1987). Having observed the ceca of many different animals for many years and having described their morphology at different levels of study -from the macroscopic to the electron microscopy level - the need to compare and observe these morphological entities in a quantitiative way became increasingly imminent. Quantitative methodol ogy in morphology requires the use of morphometry, which in the most general terms can be described as the measurement of the forms of animals. As defined by Reith and Meyhew (1988), it is quantitative morphology, i. e. , the measurement of structures by any method, including stereology.
