| morphology and anatomy: The Mandrill Alan F. Dixson, 2015-11-12 Living in the remote forests of western central Africa, the mandrill (Mandrillus sphinx) is notoriously elusive and has evaded scientific scrutiny for decades. Yet, it is the largest and most sexually dimorphic of all the Old World monkeys, and perhaps the most colourful of all the mammals. Synthesising the results of more than twenty-five years of research, this is the first extensive treatment of the mandrill's reproductive and behavioural biology. Dixson explores in detail the role that sexual selection has played in shaping the mandrill's evolution, covering mechanisms of mate choice, intra-sexual competition, sperm competition and cryptic female choice. Bringing to life, through detailed descriptions and rich illustrations, the mandrill's communicatory biology and the functions of its brightly coloured adornments, this book sheds new light on the evolutionary biology of this fascinating primate. |

| morphology and anatomy: Ecological Morphology Peter C. Wainwright, Stephen M. Reilly, 1994-08-15 Ecological morphology examines the relation between an animal's anatomy and physiology—its form and function—and how the animal has evolved in and can inhabit a particular environment. Within the past few years, research in this relatively new area has exploded. Ecological Morphology is a synthesis of major concepts and a demonstration of the ways in which this integrative approach can yield rich and surprising results. Through this interdisciplinary study, scientists have been able to understand, for instance, how bat wing design affects habitat use and bat diet; how the size of a predator affects its ability to capture and eat certain prey; and how certain mosquitoes have evolved physiologically and morphologically to tolerate salt-water habitats. Ecological Morphology also covers the history of the field, the role of the comparative method in studying adaptation, and the use of data from modern organisms for understanding the ecology of fossil communities. This book provides an overview of the achievements and potential of ecological morphology for all biologists and students interested in the way animal design, ecology, and evolution interact. |

| morphology and anatomy: Kaplan's Principles of Plant Morphology Donald Kaplan, Chelsea D. Specht, 2022-03-02 Kaplan's Principles of Plant Morphology defines the field of plant morphology, providing resources, examples, and theoretical constructs that illuminate the foundations of plant morphology and clearly outline the importance of integrating a fundamental understanding of plant morphology into modern research in plant genetics, development, and physiology. As research on developmental genetics and plant evolution emerges, an understanding of plant morphology is essential to interpret developmental and morphological data. The principles of plant morphology are being brought into studies of crop development, biodiversity, and evolution during climate change, and increasingly such researchers are turning to old texts to uncover information about historic research on plant morphology. Hence, there is great need for a modern reference and textbook that highlights past studies and provides the synthesis of data necessary to drive our future research in plant morphological and developmental evolution.

| morphology and anatomy: Arabidopsis John Bowman, 2012-12-06 The recent application of molecular genetics to problems of developmental biology has provided us with greater insight into the molecular mechanisms by which cells determine their developmental fate. This is particularly evident in the recent progress in understanding of developmental processes in model animal systems such as Drosophila melanogaster and Caenorhabditis elegans. De spite the use of plants in some of the earliest genetics experiments, the elucida tion of the molecular bases of plant development has lagged behind that of animal development. However, the emergence of model systems such as Arabi dopsis thaliana, amenable to developmental genetics, has led to the beginning of the unraveling of the mysteries behind plant morphogenesis. This atlas of the morphology and development of the weed Arabidopsis is in tended to be a reference book, both for scientists already familiar with plant anatomy and for those utilizing Arabidopsis who have come from other fields. The primary concentration is on descriptions rather than interpretations, as interpretations evolve and change relatively rapidly, whereas the evolution of plant form takes place on a much longer time scale. Molecular genetics and the use of mutants to probe wild-type gene function rely on the wild-type being well characterized. With this in mind, an attempt was made to present detailed descriptions of wild-type structure and development, to provide a foundation for comparison with the selected mutants in the atlas. More importantly, it is hoped that the atlas will serve as a valuable resource in the characterization of new mutants. |
