Download or read book The Coevolutionary Process written by John N. Thompson and published by University of Chicago Press. This book was released on 2009-04-24 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditional ecological approaches to species evolution have frequently studied too few species, relatively small areas, and relatively short time spans. In The Coevolutionary Process, John N. Thompson advances a new conceptual approach to the evolution of species interactions—the geographic mosaic theory of coevolution. Thompson demonstrates how an integrated study of life histories, genetics, and the geographic structure of populations yields a broader understanding of coevolution, or the development of reciprocal adaptations and specializations in interdependent species. Using examples of species interactions from an enormous range of taxa, Thompson examines how and when extreme specialization evolves in interdependent species and how geographic differences in specialization, adaptation, and the outcomes of interactions shape coevolution. Through the geographic mosaic theory, Thompson bridges the gap between the study of specialization and coevolution in local communities and the study of broader patterns seen in comparisons of the phylogenies of interacting species.
Download or read book Relentless Evolution written by John N. Thompson and published by University of Chicago Press. This book was released on 2013-04-12 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: At a glance, most species seem adapted to the environment in which they live. Yet species relentlessly evolve, and populations within species evolve in different ways. Evolution, as it turns out, is much more dynamic than biologists realized just a few decades ago. In Relentless Evolution, John N. Thompson explores why adaptive evolution never ceases and why natural selection acts on species in so many different ways. Thompson presents a view of life in which ongoing evolution is essential and inevitable. Each chapter focuses on one of the major problems in adaptive evolution: How fast is evolution? How strong is natural selection? How do species co-opt the genomes of other species as they adapt? Why does adaptive evolution sometimes lead to more, rather than less, genetic variation within populations? How does the process of adaptation drive the evolution of new species? How does coevolution among species continually reshape the web of life? And, more generally, how are our views of adaptive evolution changing? Relentless Evolution draws on studies of all the major forms of life—from microbes that evolve in microcosms within a few weeks to plants and animals that sometimes evolve in detectable ways within a few decades. It shows evolution not as a slow and stately process, but rather as a continual and sometimes frenetic process that favors yet more evolutionary change.

Download or read book Moths of Western North America written by Jerry A. Powell and published by Univ of California Press. This book was released on 2009 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Two of North America's most prolific and respected specialists on moths--particularly those of the West--have combined over a century of experience and scholarship to introduce western moths of all families authoritatively to both the amateur and the experienced professional entomologist. This biologically oriented and beautifully illustrated treatment of a quarter of all known western moth species fills a long-needed void, and does it superbly."--Charles V. Covell Jr., author of A Field Guide to Moths of Eastern North America "This work sets a new high water mark for North American lepidopterology. Considering the authors' century of combined studies of western Lepidoptera, it is clear from the outset that no other team could have delivered a work so rich in taxonomic and life history information, much of it being original and appearing in the literature for the first time. I will read my copy more like a novel than a reference work, casting about the accounts and repeatedly flipping through the 2300 color images to better familiarize myself with our continent's rich and handsome diversity of moths. Moths of Western North America will serve as both gateway and catalyst for the study of moths for decades, and especially for microlepidopterans--for whom no like work exists in the New World."--David L. Wagner, author of Caterpillars of Eastern North America "Recent years have seen a surge of interest in moths, with growing appreciation of their amazing diversity and their great ecological importance. Information on western moths has been scattered and scarce, however, so this new volume is a tremendous step forward. Jerry Powell and Paul Opler bring a vast amount of knowledge and experience to the subject, and their Moths of Western North America is a landmark publication, instantly indispensable to anyone with a serious interest in Lepidoptera."--Kenn Kaufman, coauthor of Kaufman Field Guide to Butterflies of North America

Download or read book Floral Diagrams written by Louis P. Ronse De Craene and published by Cambridge University Press. This book was released on 2022-04-07 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: Floral morphology is key for understanding floral evolution and plant identification. Floral diagrams are two-dimensional representations of flowers that replace extensive descriptions or elaborate drawings to convey information in a clear and unbiased way. Following the same outline as the first edition, this comprehensive guide includes updated and relevant literature, represents the latest phylogeny, and features 28 new diagrams. Diagrams are presented in the context of the most recent classifications, covering a variety of families and illustrating the floral diversity of major groups of plants. A strong didactic tool for observing and understanding floral structures, these diagrams are the obvious counterpart to any genetic study in flowering plants and to the discussion of major adaptations and evolutionary trends of flowers. This book is invaluable for researchers and students working on plant structure, development and systematics, as well as being an important resource for plant ecologists, evolutionary botanists and horticulturists.

Download or read book Saxifrages written by Malcolm McGregor and published by Timber Press. This book was released on 2008-01-01 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: The exquisite symmetry of the star-shaped blooms of saxifrages has captivated gardeners for centuries. Close observation of their fine markings, artful color combinations, and graceful presence makes it eminently clear why they attract such an enthusiastic following. Many saxifrages come from mountain habitats that make them well-suited to rock gardens, troughs, and containers, but the diverse genus includes a huge range of garden worthy plants that deserve to be better known and more widely grown. This book brings together accounts of garden and wild saxifrages, their botany, history, cultivation and propagation. All sections of genus Saxifraga are described, first discursively for the general gardener and then from a botanical viewpoint. There are the dwarf cushion saxifrages whose perfect domes of foliage are studded with jewel-like flowers, the silver saxifrages whose distinctive rosettes and fountain sprays of white flowers associate well with ordinary garden plants, and the mossy saxifrages whose highly prized cultivars have enhanced gardens since the end of the nineteenth century. Malcolm McGregor's advice on using saxifrages in different parts of the garden and his list of the top 100 saxifrages will be invaluable to gardeners new to the genus and to experts who wish to diversify. This is the fascinating story of a true enthusiast's search for saxifrages in the wild, his techniques for successful cultivation, and his continuing quest for information. It will increase understanding of this plant, inspire everyone to grow more saxifrages in their gardens, and satisfy specialists and enthusiasts for decades to come.
