Download or read book Heterochrony in Evolution written by Michael L. McKinney and published by Springer Science & Business Media. This book was released on 2013-11-21 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: ... an adult poet is simply an individual in a state of arrested development-in brief, a sort of moron. Just as all of us, in utero, pass through a stage in which we are tadpoles, ... so all of us pass through a state, in our nonage, when we are poets. A youth of seventeen who is not a poet is simply a donkey: his development has been arrested even anterior to that of the tadpole. But a man of fifty who still writes poetry is either an unfortunate who has never developed, intellectually, beyond his teens, or a conscious buffoon who pretends to be something he isn't-something far younger and juicier than he actually is. -H. 1. Mencken, High and Ghostly Matters, Prejudices: Fourth Series (1924) Where would evolution be, Without this thing, heterochrony? -M. L. McKinney (1987) One of the joys of working in a renascent field is that it is actually possible to keep up with the literature. So it is with mixed emotions that we heterochronists (even larval forms like myself) view the recent "veritable explosion of interest in heterochrony" (in Gould's words in this volume). On the positive side, it is ob viously necessary and desirable to extend and expand the inquiry; but one regrets that already we are beginning to talk past, lose track of, and even ignore each other as we carve out individual interests.

Download or read book Reproductive Allocation in Plants written by Edward Reekie and published by Elsevier. This book was released on 2011-05-04 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much effort has been devoted to developing theories to explain the wide variation we observe in reproductive allocation among environments. Reproductive Allocation in Plants describes why plants differ in the proportion of their resources that they allocate to reproduction and looks into the various theories. This book examines the ecological and evolutionary explanations for variation in plant reproductive allocation from the perspective of the underlying physiological mechanisms controlling reproduction and growth. An international team of leading experts have prepared chapters summarizing the current state of the field and offering their views on the factors determining reproductive allocation in plants. This will be a valuable resource for senior undergraduate students, graduate students and researchers in ecology, plant ecophysiology, and population biology. 8 outstanding chapters dedicated to the evolution and ecology of variation in plant reproductive allocation Written by an international team of leading experts in the field Provides enough background information to make it accessible to senior undergraduate students Includes over 60 figures and 29 tables

Download or read book Ecology And Evolution Of Plant Reproduction written by Robert Edward Wyatt and published by Springer. This book was released on 1992 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tremendous progress has been made during the past decade in the burgeoning field of plant reproductive biology. A number of quantitative and technical breakthroughs, such as horizontal starch-gel electrophoresis, have resulted in a revolution in our thinking. The study of breeding systems, which used to be marked by a rather static focus on pollination and self-incompatibility, has been transformed by dynamic models of transitional pathways, and investigators are looking not only into genetic factors but ecological ones as well. Workers in the field have recently produced detailed accounts of mating success and the relative fitness of plants as male and female parents, thus testing the applicability of sexual selection theory to plants. Ecology and Evolution of Plant Reproduction surveys recent advances in the field of plant reproductive biology and identifies fruitful avenues for future research. The contributors are well known in the fields of morphology, systematics, genetics, cell biology, and ecology, representing the full spectrum of approaches that contribute vigor to this emerging field. This new work will benefit professionals and graduate students in plant science and plant breeding, evolutionary ecology, genetics, and reproductive biology.

Download or read book Ontogeny written by P. P. G. Bateson and published by Springer Science & Business Media. This book was released on 2012-11-28 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is devoted principally to the theme of behavioral develop ment. The study of ontogeny has attracted some of the most bitter and protracted controversies in the whole field of ethology and psychology. This is partly because the arguments have reflected more general and continuing ideological battles about nature and nurture. In the opening essay, Oppenheim shows how these debates have recurred in much the same form over the last century. His chapter also brings out a more worrying feature of such argument. He demonstrates that authors who are well known for their strongly held partisan views have written in much more balanced ways than is usually admitted. Although the ex cluded middle is familiar enough in academic argument, the dynamic tensions actually present in developing systems may be particularly prone to polarize debate about what is actually happening. This point is elegantly explored by Oyama in her essay on her concept of maturation.
