Book excerpt: "Robert Michael Pyle's poems respond to details, events, and emanations from the real, physical world and its species: humans and all the rest. The poems are based on or drawn from personal experiences and perceptions, mostly out-of-doors, and will appeal to the intelligent general reader, lovers of land and literature, fans of a good poem and a good story, and naturalists--which means anyone interested in the world and its occupants beyond themselves and their immediate self-concern. Robert Michael Pyle's voice is an essential element in the culture of our literary and scientific community. His deep knowledge of the ecology of the earth and the life patterns of a wide variety of living forms, his careful attention to detail, his passion and energy and commitment to humanity that appear in his past work are present in abundance throughout the poetry in Evolution of the Genus Iris. We are fortunate readers indeed to have this new book and its poems abroad in the world."--Pattiann Rogers

Book excerpt: Irises and their relatives are lily-like plants related to the orchid and narcissus families, with whom they share a propensity for large, brightly colored, attractive flowers. Many have longlasting flowersÑIris, Gladiolus, and Freesia are among the most important cut-flower crops in the world. The intricate flowers of the iris family are finely adapted for pollination by a variety of animals, including hummingbirds, sunbirds, beetles, butterflies, moths, wasps, and bees. This intimate connection between flower form and pollination biology reveals how the marvelous range of flower colors, shapes, and scents are vital to the lives of the species. The diversity of Iridaceae is illustrated in more than 200 superb photographs supplemented by expert line drawings. A lifetime of work by the world's expert on Iridaceae is distilled in this definitive account. Botanists, ecologists, naturalists, and gardeners will find this an essential reference.

As the manager of Rainbow Iris Farm and co-editor of the Bulletin of the American Iris Society, Kelly Norris is the authority on gardening with bearded irises. His introductory chapters offer tips for successful growth, garden design, plant selection, and "creating" new irises. A Guide to Bearded Irises also provides portraits of the most outstanding plants in each of the six recognized categories, from the dainty miniature dwarf bearded irises to the stately tall bearded irises. A resource section lists specialty nurseries, organizations devoted to bearded irises, and public gardens with notable iris collections.

Costa, PhD, executive director, Highlands Biological Station and author of Darwin's Backyard #1 New Release in Nature & Ecology, Plants, Botany, Horticulture, Trees, Biological Sciences, and Nature Writing & Essays In his debut book, internationally-recognized blogger and podcaster Matt Candeias celebrates the nature of plants and the extraordinary world of plant organisms. A botanist’s defense. Since his early days of plant restoration, this amateur plant scientist has been enchanted with flora and the greater environmental ecology of the planet. Now, he looks at the study of plants through the lens of his ever-growing houseplant collection. Using gardening, houseplants, and examples of plants around you, In Defense of Plants changes your relationship with the world from the comfort of your windowsill. The ruthless, horny, and wonderful nature of plants. Understand how plants evolve and live on Earth with a never-before-seen look into their daily drama. Inside, Candeias explores the incredible ways plants live, fight, have sex, and conquer new territory. Whether a blossoming botanist or a professional plant scientist, In Defense of Plants is for anyone who sees plants as more than just static backdrops to more charismatic life forms. In this easily accessible introduction to the incredible world of plants, you’ll find: • Fantastic botanical histories and plant symbolism • Passionate stories of flora diversity and scientific names of plant organisms • Personal tales of plantsman discovery through the study of plants If you enjoyed books like The Botany of Desire, What a Plant Knows, or The Soul of an Octopus, then you’ll love In Defense of Plants.

Download or read book Plant Evolution and the Origin of Crop Species written by James F. Hancock and published by CABI. This book was released on 2012 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: The genetic variability that developed in plants during their evolution is the basic of their domestication and breeding into the crops grown today for food, fuel and other industrial uses. This third edition of Plant Evolution and the Origin of Crop Species brings the subject up-to-date, with more emphasis on crop origins. Beginning with a description of the processes of evolution in native and cultivated plants, the book reviews the origins of crop domestication and their subsequent development over time. All major crop species are discussed, including cereals, protein plants, starch crops, fruits and vegetables, from their origins to conservation of their genetic resources for future development.

Download or read book Evolution through Genetic Exchange written by Michael L Arnold and published by OUP Oxford. This book was released on 2006-07-27 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Even before the publication of Darwin's Origin of Species, the perception of evolutionary change has been a tree-like pattern of diversification - with divergent branches spreading further and further from the trunk. In the only illustration of Darwin's treatise, branches large and small never reconnect. However, it is now evident that this view does not adequately encompass the richness of evolutionary pattern and process. Instead, the evolution of species from microbes to mammals builds like a web that crosses and re-crosses through genetic exchange, even as it grows outward from a point of origin. Some of the avenues for genetic exchange, for example introgression through sexual recombination versus lateral gene transfer mediated by transposable elements, are based on definably different molecular mechanisms. However, even such widely different genetic processes may result in similar effects on adaptations (either new or transferred), genome evolution, population genetics, and the evolutionary/ecological trajectory of organisms. For example, the evolution of novel adaptations (resulting from lateral gene transfer) leading to the flea-borne, deadly, causative agent of plague from a rarely-fatal, orally-transmitted, bacterial species is quite similar to the adaptations accrued from natural hybridization between annual sunflower species resulting in the formation of several new species. Thus, more and more data indicate that evolution has resulted in lineages consisting of mosaics of genes derived from different ancestors. It is therefore becoming increasingly clear that the tree is an inadequate metaphor of evolutionary change. In this book, Arnold promotes the 'web-of-life' metaphor as a more appropriate representation of evolutionary change in all lifeforms. This research level text is suitable for senior undergraduate and graduate level students taking related courses in departments of genetics, ecology and evolution. It will also be of relevance and use to professional evolutionary biologists and systematists seeking a comprehensive and authoritative overview of this rapidly expanding field.

Download or read book Hybrid Zones and the Evolutionary Process written by Richard Gerald Harrison and published by Oxford University Press, USA. This book was released on 1993 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hybrid zones--geographical areas in which the hybrids of two races are found--have attracted the attention of evolutionary biologists for many years, both because they are windows on the evolutionary process and because the patterns of animals and plant variation seen in hybrid zones do notfit the traditional classification schemes of taxonomists. Hybrid zones provide insights into the nature of the species, the way barriers to gene exchange function, the genetic basis of those barriers, the dynamics of the speciation process. Hybrid Zones and the Evolutionary Process synthesizes theextensive research literature in this field and points to new directions in research. It will be read with interest by evolutionary biologists, geneticists, and biogeographers.
