Cleveland P. Hickman, Jr. He received his Ph. He has published numerous articles and research papers in fish physiology, in addition to co-authoring these highly successful texts: Integrated Principles of Zoology, Biology of Animals, Animal Diversity, Laboratory Studies in Animal Diversity, and Laboratory Studies in Integrated Principles of Zoology.

Over the years Dr. His interests include scuba diving, woodworking, and participating in chamber music ensembles. She received her Ph. She is a native of Canada and obtained her undergraduate education at the University of British Columbia in Vancouver.

Keen is an invertebrate zoologist fascinated with sea jelly life histories. She has a particular interest in life cycles where both asexual and sexual phases of organisms are present, as they are in most jellies. Her other research has included work on sessile marine invertebrate communities, spider populations, and Andean potato evolution. Keen has been teaching evolution and animal diversity within the Introductory Biology series for 22 years.

She enjoys all facets of the teaching process, from lectures and discussions to the design of click laboratory exercises. In addition to her work with introductory biology, she offers seminars on teaching methods in biology, and works with an animator to create self-guided teaching modules on animal development. Her interests include horseback riding, gardening, travel, and mystery novels. He teaches courses in environmental science, human anatomy, mammalogy, general zoology, comparative continue reading, ichthyology, and vertebrate zoology. David has an active research program cells in many celled organisms focuses on systematics, conservation biology, and natural history of North American freshwater fishes.

He and his students have authored several publications. David serves as an academic advisor to prepharmacy students. His interests include fishing, landscaping, softball, hiking, and entertaining his three children, who, along with his wife, are enthusiastic participants in fieldwork.

Louis, MO. His fields of specialization include evolutionary biology, molecular population genetics and systematics, and amphibian systematics. He teaches courses in introductory genetics, zoology, macroevolution, molecular evolution, and the history of evolutionary theory, and has organized and taught a special course in evolutionary biology for high-school teachers.

Larson serves as an academic advisor to undergraduate students and supervises the undergraduate biology curriculum at Washington University. She teaches courses in animal physiology, microanatomy, neuroendocrinology, cells in many celled organisms biology, and reproductive physiology. She has an active research program that focuses on the neural regulation of energy partitioning during development using the female go here rat.

In particular, she is interested in mechanisms regulating the development of childhood obesity. Currently, she is studying the role of snacking from weaning to adulthood in the onset of childhood obesity. Her interests include gardening, hiking, fishing, aromatherapy, music, orgabisms participating in choral ensembles. With the seventeenth edition, the authors bring a wealth of real experience as they describe the diversity of animal life and the fascinating adaptations that enable animals to inhabit so many ecological niches.

The overall organization of this text has proven to work well to help students understand the content. Distinctive features, especially the emphasis on principles of evolution and zoological science, have been strengthened. Authors received a heat map of the sixteenth edition, showing for each paragraph the percentage of correct student responses for that material. With this detailed and insightful guidance, we have made our text more accessible to its readers. In addition to focused revision of the cells in many celled organisms, we have replaced many photographs and diagrams throughout the book to improve clarity and vibrancy.

Regarding general properties of living systems, we expand the explanation of speciation as part of continue reading biological hierarchy, and extend the principle of movement to the macromolecular level, emphasizing reversible conformational changes in cells in many celled organisms. In Chapter 2, expanded captions for Figures 2. The important role of ATP in cellular x metabolism and as a precursor mahy RNA gets expanded treatment, as does the role of membrane-bound vesicles in the evolution of biological polymers. Chapter 3 features a new explanation of electron microscopy, more information on the Golgi apparatus and on how cells adapt to temperature, and a more detailed description of how spindle fibers organize chromosomes for cellular division. Chapter 6 contains a more complete explanation of geological dating, a reorganized section, Forces of Evolutionary Change, and a new section describing studies of Caribbean ectoprocts as the best-documented case of punctuated equilibrium.]
