Download or read book Diversity and Classification of Flowering Plants written by Armen Leonovich Takhtadzhi͡an and published by Columbia University Press. This book was released on 1997 with total page 662 pages. Available in PDF, EPUB and Kindle. Book excerpt: The culmination of more than fifty years of research by the foremost living expert on plant classification, Diversity and Classification of Flowering Plants is an important contribution to the field of plant taxonomy. In the last decade, the system of classifying plants has been thoroughly revised. Instead of describing every individual family, Takhtajan includes descriptions in keys to families, which he calls "descriptive keys." The advantage of descriptive keys is that they give both the characteristic features of the families and their differences. The delimitation of families and orders drastically differs from the one accepted by the Englerian school and from the one accepted in Arthur Cronquist's system. Takhtajan favors the smaller, more natural families and orders, which are more coherent and better-defined, where characters are easily grasped, and which are more suitable for information retrieval and phylogenetic studies, including cladistic analysis (because it reduces polymorphic codings).

Download or read book Defending the Land of the Jaguar written by Lane Simonian and published by University of Texas Press. This book was released on 1995 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mexican conservationists have sometimes observed that it is difficult to find a country less interested in the conservation of its natural resources than is Mexico. Yet, despite a long history dedicated to the pursuit of development regardless of its environmental consequences, Mexico has an equally long, though much less developed and appreciated, tradition of environmental conservation. Lane Simonian here offers the first panoramic history of conservation in Mexico from pre-contact times to the current Mexican environmental movement. He explores the origins of conservation and environmental concerns in Mexico, the philosophies and endeavors of Mexican conservationists, and the enactment of important conservation laws and programs. This heretofore untold story, drawn from interviews with leading Mexican conservationists as well as archival research, will be important reading throughout the international community of activists, researchers, and concerned citizens interested in the intertwined issues of conservation and development.

Download or read book Avian Poultry Production written by Carin Fisker and published by . This book was released on 2016-04-01 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Poultry has a crucial place worldwide as the eggs and chicken meat are important and rich sources of protein, vitamins and minerals. Poultry provides rich organic manure and is an important source of income and employment to millions of farmers and other persons engaged in allied activities in the poultry industry. Chickens and turkeys that are commercially raised today are the result of many years of selection and breeding of two or more breeds to continually improve productivity. Poultry farming is the raising of domesticated birds such as chickens, ducks, turkeys and geese for the purpose of farming meat or eggs for food. Poultry are farmed in great numbers with chickens being the most numerous. More than 50 billion chickens are raised annually as a source of food, for both their meat and their eggs. The chicken industry is made up of meatproducing chickens and egg-producing chickens. The modern meat-type chicken is derived from the deep-breasted Cornish breed and has been selected with an emphasis on producing meat rather than eggs. Further processing of meat chickens has led to many new products geared to the convenienceminded consumer, such as boneless, skinless breasts. The turkey industry has developed strains of birds with an emphasis on meat production and breast size, as the white meat has a higher market value in the United States. Many pure breeds of poultry are raised for exhibition, hobby and/or breed preservation purposes. There is lots to discover with the comprehensive poultry production. We all know that in order to get the best out of birds, poultry keepers need to be up to date with the latest ideas and techniques. The book Avian (Poultry) Production discusses about the anatomy and physiology of birds, building them the best housing, breeding, egg production and also about preventing parasites and diseases.

Download or read book Maya Subsistence written by Kent V. Flannery and published by Academic Press. This book was released on 1982-02-28 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maya Subsistence: Studies in Memory of Dennis E. Puleston presents studies on the history and development of Maya subsistence in honor of Maya archaeologist Dennis E. Puleston (1940-1978). The discussions are organized around four themes: ecological models for early Maya adaptations; archaeological investigations of Pre-classic and classic Maya subsistence; contributions of geography and soil science to an understanding of ancient Maya subsistence; and Maya subsistence in the post-classic, colonial, and modern eras. Comprised of 15 chapters, this book begins with an analysis of Puleston's career and a review of the history of inquiry into Maya subsistence. Maya subsistence from the earliest Pre-classic period up to the present day is then examined, with emphasis on agriculture, hunting, wild plant collecting, animal husbandry, and trade. In particular, cultural development in the Valley of Guatemala from 1500 B.C. to the Spanish Conquest is discussed, along with the resources of the tropical lowlands and actual prehistoric cornfields miraculously preserved by volcanic ashfall in El Salvador. The book also presents evidence for Maya soil and water conservation over the entire area from Yucatan to Chiapas and central Guatemala, and looks at the traditional role of women and animals in lowland Maya economy. This monograph will be of interest to archaeologists and anthropologists.

Download or read book Agroforestry for Ecosystem Services and Environmental Benefits written by Shibu Jose and published by Springer. This book was released on 2012-03-14 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agroforestry systems are believed to provide a number of ecosystem services; however, until recently evidence in the agroforestry literature supporting these perceived benefits has been lacking. This volume brings together a series of papers from around the globe to address recent findings on the ecosystem services and environmental benefits provided by agroforestry. Specifically, this volume examines four major ecosystem services and environmental benefits: (1) carbon sequestration, (2) biodiversity conservation, (3) soil enrichment and (4) air and water quality. Past and present evidence clearly indicates that agroforestry, as part of a multifunctional working landscape, can be a viable land-use option that, in addition to alleviating poverty, offers a number of ecosystem services and environmental benefits. This realization should help promote agroforestry and its role as an integral part of a multifunctional working landscape the world over. The book should be particularly useful to students, professionals, researchers and policy makers involved in natural resource management, agroforestry, biodiversity conservation, and environmental management.
