Download or read book Biological Diversity of Mexico written by T. P. Ramamoorthy and published by . This book was released on 1993 with total page 864 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mexico is among the richest countries in the world in terms of the number of native animal and plant species. Found in a wide variety of habitats--from alpine meadows and tropical forests to vast stretches of desert and isolated pockets of biogeographical uniqueness--these species comprise a fascinating, important, and vastly underutilized biological laboratory. This volume presents a collection of selected papers that explore this marvelous biological abundance. The book is divided into six parts. The first section sets the stage with geological and paleobotanical overviews; the succeeding five sections employ a strong taxonomic base to document species richness, endemism and distribution for animals and plants, followed by reviews of contrasting ecosystems and plants that are closely associated with humans. The last section summarizes the disheartening rate of habitat destruction which threatens to diminish this diversity. In addition to the purely scientific value of this important work, it provides the much-needed basic data that will help conservation policymakers assess and respond to Mexico's ecological evolution.
Download or read book Hot Deserts and Arid Shrublands written by Michael Evenari and published by Elsevier Science & Technology. This book was released on 1985 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: This two-volume work presents an authoritative world-wide view of our knowledge about, and understanding of, hot-desert ecosystems. This includes some semi-arid and arid areas, as well as deserts in the strict sense. The hot deserts are distinguished from the temperate deserts (which form the subject of another volume in the series) by the virtual absence of snowfall, even though frosts may occur. For each major hot-desert region, expert authors have summarized existing knowledge according to a general outline. This includes descriptions of the ecosystem components (climate, soil, flora and fauna), and discussion of interaction between components and overall ecosystem functioning. The information from the regional chapters has then been integrated into a world-wide view in the ''synthesis'' chapters. Because of its length, the volume is published in two parts. The first volume includes the general synthesis chapters, and regional descriptions of the hot deserts of America and Australia, while the second volume covers the hot deserts of Asia and Africa.

Download or read book Darwin s Harvest written by Timothy J. Motley and published by Columbia University Press. This book was released on 2006-01-04 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Darwin's Harvest addresses concerns that we are losing the diversity of crop plants that provide food for most of the world. With contributions from evolutionary biologists, geneticists, agronomists, molecular biologists, and anthropologists, this collection discusses how economic development, loss of heirloom varieties and wild ancestors, and modern agricultural techniques have endangered the genetic diversity needed to keep agricultural crops vital and capable of adaptation. Drawing on the most up-to-date data, the contributors review the utilization of molecular techniques to understand crop evolution. They explore current research on various crop plants of both temperate and tropical origin, including maize, sunflower, avocado, sugarcane, and wheat. The chapters in Darwin's Harvest also provide solid background for understanding many recent discoveries concerning the origins of crops and the influence of human migration and farming practices on the genetics of our modern foods.
Download or read book Archaeology of Communities written by Marcello-Andrea Canuto and published by Routledge. This book was released on 2012-11-12 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Archaeology of Communities develops a critical evaluation of community and shows that it represents more than a mere aggregation of households. This collection bridges the gap between studies of ancient societies and ancient households. The community is taken to represent more than a mere aggregation of households, it exists in part through shared identities, as well as frequent interaction and inter-household integration. Drawing on case studies which range in location from the Mississippi Valley to New Mexico, from the Southern Andes to the Blue Ridge Mountains of Madison County, Virginia, the book explores and discusses communities from a whole range of periods, from Pre-Columbian to the late Classic. Discussions of actual communities are reinforced by strong debate on, for example, the distinction between 'Imagined Community' and 'Natural Community.'

Download or read book Origins of the uu written by Stephen A. Kowalewski and published by University Press of Colorado. This book was released on 2011-06-13 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Combining older findings with new data on 1,000 previously undescribed archaeological sites, Origins of the Ñuu presents the cultural evolution of the Mixteca Alta in an up-to-date chronological framework. The ñuu - the kingdoms of the famous Mixtec codices - are traced back through the Postclassic and Classic periods to their beginnings in the first states of the Terminal Formative, revealing their origin, evolution, and persistence through two cycles of growth and collapse. Challenging assumptions that the Mixtec were peripheral to better-known peoples such as the Aztecs or Maya, the book asserts that the ñuu were a major demographic and economic power in their own right. Older explanations of multiregional or macroregional systems often portrayed civilizations as rising in a cradle or hearth and spreading outward. New macroregional studies show that civilizations are products of more complex interactions between regions, in which peripheries are not simply shaped by cores but by their interactions with multiple societies at varying distances from major centers. Origins of the Ñuu is a significant contribution to this emerging area of archaeological research.
Download or read book Chipped Stone Tool Use in the Maya Coastal Economies of Marco Gonzalez and San Pedro Ambergris Caye Belize written by William James Stemp and published by British Archaeological Reports Oxford Limited. This book was released on 2001 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: A highly detailed analysis of stone tools recovered from excavations at two sites on the coral island of Ambergris Caye, off the coast of Belize, which revealed evidence of continued occupation on the island from c.100 BC until well into the Historic period. The study of the wear of tools provides a clear picture of the ways in which the Maya exploited the island's natural resources, notably fish, shell, coral and salt, while comparison of the sites shows the level of interaction between communities. Sections present a tool typology and discuss lithic technology, raw materials and the archaeological context and distribution of the assemblages.

Download or read book Unfinished Synthesis written by Niles Eldredge and published by Oxford University Press. This book was released on 1985-11-21 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study provides a stimulating critique of contemporary evolutionary thought, analyzing the Modern Synthesis first developed by Theodosius Dobzhansky, Ernst Mayr, and George Gaylord Simpson. The author argues that although only genes and organisms are taken as historic "individuals" in conventional theory, species, higher taxa, and ecological entities such as populations and communities should also be construed as individuals--an approach that yields the ecological and genealogical hierarchies that interact to produce evolution. This clearly stated, controversial work will provoke much debate among evolutionary biologists, systematists, paleontologists, and ecologists, as well as a wide range of educated lay readers.

Download or read book Maya History written by Tatiana Proskouriakoff and published by University of Texas Press. This book was released on 2011-01-19 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tatiana Proskouriakoff, a preeminent student of the Maya, made many breakthroughs in deciphering Maya writing, particularly in demonstrating that the glyphs record the deeds of actual human beings, not gods or priests. This discovery opened the way for a history of the Maya, a monumental task that Proskouriakoff was engaged in before her death in 1985. Her work, Maya History, has been made ready for press by the able editorship of Rosemary Joyce. Maya History reconstructs the Classic Maya period (roughly A.D. 250-900) from the glyphic record on stelae at numerous sites, including Altar de Sacrificios, Copan, Dos Pilas, Naranjo, Piedras Negras, Quirigua, Tikal, and Yaxchilan. Proskouriakoff traces the spread of governmental institutions from the central Peten, especially from Tikal, to other city-states by conquest and intermarriage. Thirteen line drawings of monuments and over three hundred original drawings of glyphs amplify the text.
