Download or read book Columnar Cacti and Their Mutualists written by Theodore H. Fleming and published by University of Arizona Press. This book was released on 2021-11-30 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although cacti such as the saguaro and organ pipe have come to define the Sonoran Desert for many people, they represent some 170 species of columnar cacti found in many parts of the Americas. These giant plants are so dominant in some ecosystems that many species of animals rely on them for food and shelter. They are pollinated by bats in central Mexico and Venezuela, by birds and bees in northern Mexico and Peru. This book summarizes our knowledge about the ecology, evolution, and conservation of columnar cacti and their vertebrate mutualists to show that the very survival of these cacti depends on animals who pollinate them and disperse their seeds. Contributors from the United States, Mexico, Venezuela, and Colombia explore aspects of geology and evolution that have forged this relationship, review findings in anatomy and physiology, and discuss recent research in population and community ecology as well as conservation issues. Ranging from the Sonoran Desert to the northern Andes, these studies reflect progress in understanding how abiotic and biotic factors interact to influence the evolution, distribution, and abundance of cacti and mutualists alike. In addition, this book examines the ways in which humans, through the process of domestication, have modified these plants for economic benefit. The contributors also review phylogenetic relationships between cacti and nectar-feeding bats in an effort to understand how bat-plant interactions have influenced the evolution of diversity and ecological specialization of both. Because of the number of migratory pollinators feeding on columnar cacti, the authors make conservation recommendations aimed at preserving fully functional ecosystems in arid portions of the New World tropics and subtropics. Columnar Cacti and Their Mutualists provided a benchmark for both conservation efforts and future research.

Available in PDF, EPUB and Kindle. Book excerpt: As Spain colonized the Americas during the sixteenth century, Spanish soldiers, bureaucrats, merchants, adventurers, physicians, ship pilots, and friars explored the natural world, gathered data, drew maps, and sent home specimens of America's vast resources of animals, plants, and minerals. This amassing of empirical knowledge about Spain's American possessions had two far-reaching effects. It overturned the medieval understanding of nature derived from Classical texts and helped initiate the modern scientific revolution. And it allowed Spain to commodify and control the natural resources upon which it built its American empire. In this book, Antonio Barrera-Osorio investigates how Spain's need for accurate information about its American colonies gave rise to empirical scientific practices and their institutionalization, which, he asserts, was Spain's chief contribution to the early scientific revolution. He also conclusively links empiricism to empire-building as he focuses on five areas of Spanish activity in America: the search for commodities in, and the ecological transformation of, the New World; the institutionalization of navigational and information-gathering practices at the Spanish Casa de la Contratación (House of Trade); the development of instruments and technologies for exploiting the natural resources of the Americas; the use of reports and questionnaires for gathering information; and the writing of natural histories about the Americas.

Download or read book Race and Reproduction in Cuba written by Bonnie A. Lucero and published by University of Georgia Press. This book was released on 2022-11 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: Women’s reproduction, including conception, pregnancy, childbirth, breastfeeding, and other physical acts of motherhood (as well as the rejection of those roles), played a critical role in the evolution and management of Cuba’s population. While existing scholarship has approached Cuba’s demographic history through the lens of migration, both forced and voluntary, Race and Reproduction in Cuba challenges this male-normative perspective by centering women in the first book-length history of reproduction in Cuba. Bonnie A. Lucero traces women’s reproductive lives, as well as key medical, legal, and institutional interventions influencing them, over four centuries. Her study begins in the early colonial period with the emergence of the island’s first charitable institutions dedicated to relieving poor women and abandoned white infants. The book’s centerpiece is the long nineteenth century, when elite interventions in women’s reproduction hinged not only on race but also legal status. It ends in 1965 when Cuba’s nascent revolutionary government shifted away from enforcing antiabortion laws that had historically targeted impoverished women of color. Questioning how elite demographic desires—specifically white population growth and nonwhite population management—shaped women’s reproduction, Lucero argues that elite men, including judges, physicians, philanthropists, and public officials, intervened in women’s reproductive lives in racially specific ways. Lucero examines how white supremacy shaped tangible differences in the treatment of women and their infants across racial lines and outlines how those reproductive outcomes were crucial in sustaining racial hierarchies through moments of tremendous political, economic, and social change.

Available in PDF, EPUB and Kindle. Book excerpt: "Passionate and meticulous . . . [Ehrlich] delivers thought-provoking metaphors, unforgettable scenes and many beautifully worded phrases." —Benjamin Labatut, The New York Times Book Review One of The Telegraph's best books of the year The first major biography of the Nobel Prize–winning scientist who discovered neurons and transformed our understanding of the human mind—illustrated with his extraordinary anatomical drawings Unless you’re a neuroscientist, Santiago Ramón y Cajal is likely the most important figure in the history of biology you’ve never heard of. Along with Charles Darwin and Louis Pasteur, he ranks among the most brilliant and original biologists of the nineteenth century, and his discoveries have done for our understanding of the human brain what the work of Galileo and Sir Isaac Newton did for our conception of the physical universe. He was awarded the Nobel Prize in 1906 for his lifelong investigation of the structure of neurons: “The mysterious butterflies of the soul,” Cajal called them, “whose beating of wings may one day reveal to us the secrets of the mind.” And he produced a dazzling oeuvre of anatomical drawings, whose alien beauty grace the pages of medical textbooks and the walls of museums to this day. Benjamin Ehrlich’s The Brain in Search of Itself is the first major biography in English of this singular figure, whose scientific odyssey mirrored the rocky journey of his beloved homeland of Spain into the twentieth century. Born into relative poverty in a mountaintop hamlet, Cajal was an enterprising and unruly child whose ambitions were both nurtured and thwarted by his father, a country doctor with a flinty disposition. A portrait of a nation as well a biography, The Brain in Search of Itself follows Cajal from the hinterlands to Barcelona and Madrid, where he became an illustrious figure—resisting and ultimately transforming the rigid hierarchies and underdeveloped science that surrounded him. To momentous effect, Cajal devised a theory that was as controversial in his own time as it is universal in ours: that the nervous system is comprised of individual cells with distinctive roles, just like any other organ in the body. In one of the greatest scientific rivalries in history, he argued his case against Camillo Golgi and prevailed. In our age of neuro-imaging and investigations into the neural basis of the mind, Cajal is the artistic and scientific forefather we must get to know. The Brain in Search of Itself is at once the story of how the brain as we know it came into being and a finely wrought portrait of an individual as fantastical and complex as the subject to which he devoted his life.
