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 Handbook on the History of Mathematics Education written by Alexander Karp and published by Springer Science & Business Media. This book was released on 2014-01-25 with total page 627 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first comprehensive International Handbook on the History of Mathematics Education, covering a wide spectrum of epochs and civilizations, countries and cultures. Until now, much of the research into the rich and varied history of mathematics education has remained inaccessible to the vast majority of scholars, not least because it has been written in the language, and for readers, of an individual country. And yet a historical overview, however brief, has become an indispensable element of nearly every dissertation and scholarly article. This handbook provides, for the first time, a comprehensive and systematic aid for researchers around the world in finding the information they need about historical developments in mathematics education, not only in their own countries, but globally as well. Although written primarily for mathematics educators, this handbook will also be of interest to researchers of the history of education in general, as well as specialists in cultural and even social history.
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.

Download or read book Neotropical Owls written by Paula L. Enriquez and published by Springer. This book was released on 2017-07-24 with total page 673 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive biological and ecological information about owls in the neotropic area. In addition the book covers topics such as threats and conservation strategies for these nocturnal birds of prey from 18 Neotropical countries. Owls are a good example of diversification processes and have developed evolutionary characteristics themselves. These species are found almost everywhere in the world but most of them are distributed in tropical areas and about a third of them live in the Neotropics. This biogeographic region has a high biodiversity and even share lineages of species from other continents because at some point all were part of Pangea. Although we still have much to know and understand about this diverse, scarcely studied and threatened group this work aims to be a precedent for future and further research on the subject.

This book was released on 2020-08-29 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food security, crop protection, biodiversity, and human and environmental health are among the main needs and concerns of society. Modern biotechnology and life sciences represent a constantly evolving area that is key for the rational use of natural resources – resources that in turn are indispensable for societal development. This book features the outcomes of the IV International Biotechnology and Biodiversity Congress, held in Guayaquil, Ecuador, 2018. It includes extensive reviews of the trends in agricultural and forestry biotechnology, molecules and materials biodiscovery, ethnomedicine, environmental impact and bioindustry research, describing many of these topics from the Latin America perspective and showing how the biodiversity and ancient knowledge of these countries are vital for worldwide sustainable development.
