Book excerpt: In the tradition of Silent Spring, Raoul Robinson's Return to Resistance calls for a revolution. Traditional plant breeding techniques have led us to depend more and more on chemical pesticides to protect ourcrops. Return to Resistance shows gardeners, farmers, and plant breeders how to use a long-neglected technique to create hardy new plant varieties that are naturally resistant to pests and disease. Horizontal resistance breeding has been largely ignored in this century due to the popularity and apparent successes of the Mendelian geneticists. However the colossal, unrecognized failure of m.

Download or read book My Antonia written by Willa Cather and published by Gildan Media LLC aka G&D Media. This book was released on 2024-01-02 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: A haunting tribute to the heroic pioneers who shaped the American Midwest This powerful novel by Willa Cather is considered to be one of her finest works and placed Cather in the forefront of women novelists. It tells the stories of several immigrant families who start new lives in America in rural Nebraska. This powerful tribute to the quiet heroism of those whose struggles and triumphs shaped the American Midwest highlights the role of women pioneers, in particular. Written in the style of a memoir penned by Antonia’s tutor and friend, the book depicts one of the most memorable heroines in American literature, the spirited eldest daughter of a Czech immigrant family, whose calm, quite strength and robust spirit helped her survive the hardships and loneliness of life on the Nebraska prairie. The two form an enduring bond and through his chronicle, we watch Antonia shape the land while dealing with poverty, treachery, and tragedy. “No romantic novel ever written in America...is one half so beautiful as My Ántonia.” -H. L. Mencken Willa Cather (1873–1947) was an American writer best known for her novels of the Plains and for One of Ours, a novel set in World War I, for which she was awarded the Pulitzer Prize in 1923. She was elected a fellow of the American Academy of Arts and Sciences in 1943 and received the gold medal for fiction from the National Institute of Arts and Letters in 1944, an award given once a decade for an author's total accomplishments. By the time of her death she had written twelve novels, five books of short stories, and a collection of poetry.

Book excerpt: When the young Swedish-descended Alexandra Bergson inherits her father's farm in Nebraska, she must transform the land from a wind-swept prairie landscape into a thriving enterprise. She dedicates herself completely to the land—at the cost of great sacrifices. O Pioneers! [1913] is Willa Cather's great masterpiece about American pioneers, where the land is as important a character as the people who cultivate it. WILLA CATHER [1873-1947] was an American author. After studying at the University of Nebraska, she worked as a teacher and journalist. Cather's novels often focus on settlers in the USA with a particular emphasis on female pioneers. In 1923, she was awarded the Pulitzer Prize for the novel One of Ours, and in 1943, she was elected to the American Academy of Arts and Sciences.

Download or read book Comparative and Evolutionary Genomics of Angiosperm Trees written by Andrew Groover and published by Springer. This book was released on 2017-11-21 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marking the change in focus of tree genomics from single species to comparative approaches, this book covers biological, genomic, and evolutionary aspects of angiosperm trees that provide information and perspectives to support researchers broadening the focus of their research. The diversity of angiosperm trees in morphology, anatomy, physiology and biochemistry has been described and cataloged by various scientific disciplines, but the molecular, genetic, and evolutionary mechanisms underlying this diversity have only recently been explored. Excitingly, advances in genomic and sequencing technologies are ushering a new era of research broadly termed comparative genomics, which simultaneously exploits and describes the evolutionary origins and genetic regulation of traits of interest. Within tree genomics, this research is already underway, as the number of complete genome sequences available for angiosperm trees is increasing at an impressive pace and the number of species for which RNAseq data are available is rapidly expanding. Because they are extensively covered by other literature and are rapidly changing, technical and computational approaches—such as the latest sequencing technologies—are not a main focus of this book. Instead, this comprehensive volume provides a valuable, broader view of tree genomics whose relevance will outlive the particulars of current-day technical approaches. The first section of the book discusses background on the evolution and diversification of angiosperm trees, as well as offers description of the salient features and diversity of the unique physiology and wood anatomy of angiosperm trees. The second section explores the two most advanced model angiosperm tree species (poplars and eucalypts) as well as species that are soon to emerge as new models. The third section describes the structural features and evolutionary histories of angiosperm tree genomes, followed by a fourth section focusing on the genomics of traits of biological, ecological, and economic interest. In summary, this book is a timely and well-referenced foundational resource for the forest tree community looking to embrace comparative approaches for the study of angiosperm trees.

Book excerpt: "Drawing on sources ranging from gardening books and magazines to statistics and oral history, Harvest of the suburbs challenges some widespread myths about food production in Australian cities, and traces the reasons for its enduring popularity. It describes changing attitudes and techniques, and explores the relationship between food production and a range of contemporary ideas relating to work, social organisation, gender roles, health and the body, and nature. In doing so, it provides new insights into the tension between the quest for independence and the desire for interdependence in suburban Australia." --book cover.
