This book was released on 2016-06-27 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Variations and Genetic Relationships of the Garter-Snakes Three steps are necessary to determine the genetic relationships and simplify Cope's elaborate arrangement of the group: (1) The value of the characters must be determined; (2) the geographic prob abilities must be utilized; (3) similarities and intergradations must be sought. It may seem super uous to insist upon the determination of the value of the characters used in systematic work on this group, for good characters, i. E., those which are constant within particular groups, are sought after by most systematists in forming their taxo nomic groups, but in the sense in which it is here used this rule means more than this, in that it also requires the discovery of the significance of the variations.

This book was released on 2017-09-19 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: Object Lessons and the Formation of Knowledge explores the museums, libraries, and special collections of the University of Michigan on its bicentennial. Since its inception, U-M has collected and preserved objects: biological and geological specimens; ethnographic and archaeological artifacts; photographs and artistic works; encyclopedia, textbooks, rare books, and documents; and many other items. These vast collections and libraries testify to an ambitious vision of the research university as a place where knowledge is accumulated, shared, and disseminated through teaching, exhibition, and publication. Today, two hundred years after the university’s founding, museums, libraries, and archives continue to be an important part of U-M, which maintains more than twenty distinct museums, libraries, and collections. Viewed from a historic perspective, they provide a window through which we can explore the transformation of the academy, its public role, and the development of scholarly disciplines over the last two centuries. Even as they speak to important facets of Michigan’s history, many of these collections also remain essential to academic research, knowledge production, and object-based pedagogy. Moreover, the university’s exhibitions and displays attract hundreds of thousands of visitors per year from the campus, regional, and global communities. Beautifully illustrated with color photographs of these world-renowned collections, this book will appeal to readers interested in the history of museums and collections, the formation of academic disciplines, and of course the University of Michigan.

Download or read book Chemical Signals in Vertebrates 4 written by David Duvall and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume reviews recent developments in our understanding of che~ ical signaling in vertebrates. After sections dealing with general princi ples and chemical aspects of vertebrate pheromones, it follows a taxonomic approach, progressing from fish to. mammals. The editors asked a diverse, international group of leading investigators, working on a wide array of vertebrate taxa and specific issues, to consider their efforts from compar ative, evolutionary, and ecological viewpoints. The relative number of manuscripts in each part does not necessarily reflect current intensity of research, since the editors invited speakers who together would provide a balanced and comprehensive overview, while avoiding duplication. Still, the part on mammals is the longest. Fourth in a series dating from 1977, this volume illuminates current trends and likely future developments in the field of chemical signaling in vertebrates. Going back even farther, the first chapter, a personal account of the past quarter century by Dr. Mykytowycz recalls the most important milestones, such as symposia, or the founding of societies and journals. He also credits those investigators who stand out by their seminal studies.
Download or read book Evolutionary Quantitative Genetics written by Stevan J. Arnold and published by Oxford University Press. This book was released on 2023-06-06 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evolutionary quantitative genetics (EQG) provides a formal theoretical foundation for quantitatively linking natural selection and genetic variation to the rate and expanse of adaptive evolution. It has become the dominant conceptual framework for interpreting the evolution of quantitative traits in terms of elementary forces (mutation, inheritance, selection, and drift). Despite this success, the relevance of EQG to many biological scenarios remains relatively unappreciated, with numerous fields yet to fully embrace its approach. Part of the reason for this lag is that conceptual advances in EQG have not yet been fully synthesized and made accessible to a wider academic audience. A comprehensive, accessible overview is therefore now timely, and Evolutionary Quantitative Genetics provides this much-needed synthesis. The central argument of the book is that an adaptive landscape concept can be used to understand both evolutionary process within lineages and the pattern of adaptive radiations. In particular, it provides a convincing argument that models with a moving adaptive peak carry us further than any other conceptual approach yet devised. Although additive theory holds center stage, the book mentions and references departures from additivity including non-Gaussian distributions of allelic effects, dominance, epistasis, maternal effects and phenotypic plasticity. This accessible, advanced textbook is aimed principally at students (from senior undergraduate to postgraduate) as well as practising scientists in the fields of evolutionary biology, ecology, physiology, functional morphology, developmental biology, comparative biology, paleontology, and beyond who are interested in how adaptive radiations are produced by evolutionary and ecological processes.
