This book presents an evolutionary biogeographic analysis of the Mexican Transition Zone, which is situated in the overlap of the Nearctic and Neotropical regions. It includes a comprehensive review of previous track, cladistic and molecular biogeographic analyses and is illustrated with full color maps and vegetation photographs of the respective areas covered. Given its scope, the book will be of interest to students and researchers whose work involves systematic and biogeographic analyses of plant and animal taxa of the Mexican Transition Zone or other transition zones of the world, and to ecologists working in biodiversity conservation, who will be able to appreciate the evolutionary relevance of the Mexican Transition Zone for establishing conservation areas..
Neotropical Biogeography: Regionalization and Evolution presents the most comprehensive single-source treatment of the Neotropical region derived from evolutionary biogeographic studies. The book provides a biogeographic regionalization based on distributional patterns of plant and animal taxa, discusses biotic relationships drawn from track and cladistic biogeographic analyses, and identifies cenocrons (subsets of taxa within biotas identified by their common origin and evolutionary history). It includes maps, area cladograms and vegetation profiles. The aim of this reference is to provide a biogeographic regionalization that can be used by graduate students, researchers and other professionals concerned with understanding and describing distributional patterns of plants and animals in the Neotropical region. It covers the 53 biogeographic provinces of the Neotropical region that are classified into the Antillean, Brazilian and Chacoan subregions, and the Mexican and South American transition zones.
This book addresses the technical, health, regulatory, and social aspects of ground water withdrawals, water use, and water quality in the metropolitan area of Mexico City, and makes recommendations to improve the balance of water supply, water demand, and water conservation. The study came about through a nongovernmental partnership between the U.S. National Academy of Sciences' National Research Council and the Mexican Academies of Science and Engineering. The book will contain a Spanish-language translation of the complete English text.
This volume provides a comprehensive analysis of the economic, social, cultural and political dimensions of the evolving trilateral relationship among the three countries of North America. Contributors address such topics as energy, the environment, trade, labour, the maquiladora industrial sector of Mexico, the Mexican auto industry, and Canada - U.S. cultural relations.While other publications have focused on U.S. issues, this one emphasizes Canada and Mexico, yet adds significantly to our understanding of the place of the United States in this evolving trilateral relationship.
One of the most surprising developments in Mexico's transition to democracy is the outbreak of criminal wars and large-scale criminal violence. Why did Mexican drug cartels go to war as the country transitioned away from one-party rule? And why have criminal wars proliferated as democracy has consolidated and elections have become more competitive subnationally? In Votes, Drugs, and Violence, Guillermo Trejo and Sandra Ley develop a political theory of criminal violence in weak democracies that elucidates how democratic politics and the fragmentation of power fundamentally shape cartels' incentives for war and peace. Drawing on in-depth case studies and statistical analysis spanning more than two decades and multiple levels of government, Trejo and Ley show that electoral competition and partisan conflict were key drivers of the outbreak of Mexico's crime wars, the intensification of violence, and the expansion of war and violence to the spheres of local politics and civil society.
The United States-Mexico border zone is one of the busiest and most dangerous in the world. NAFTA and rapid industrialization on the Mexican side have brought trade, travel, migration, and consequently, organized crime and corruption to the region on an unprecedented scale. Until recently, crime at the border was viewed as a local law enforcement problem with drug trafficking—a matter of "beefing" up police and "hardening" the border. At the turn of the century, that limited perception has changed. The range of criminal activity at the border now extends beyond drugs to include smuggling of arms, people, vehicles, financial instruments, environmentally dangerous substances, endangered species, and archeological objects. Such widespread trafficking involves complex, high-level criminal-political alliances that local lawenforcement alone can't address. Researchers of the region, as well as officials from both capitals, now see the border as a set of systemic problems that threaten the economic, political, and social health of their countries as a whole. Organized Crime and Democratic Governability brings together scholars and specialists, including current and former government officials, from both sides of the border to trace the history and define the reality of this situation. Their diverse perspectives place the issue of organized crime in historical, political, economic, and cultural contexts unattainable by single-author studies. Contributors examine broad issues related to the political systems of both countries, as well as the specific actors—crime gangs, government officials, prosecutors, police, and the military—involved in the ongoing drama of the border. Editors Bailey and Godson provide an interpretive frame, a "continuum of governability," that will guide researchers and policymakers toward defining goals and solutions to the complex problem that, along with a border, the United States and Mexico now share.
An exploration of the interrelated trends of Mexico's transitional politics and society. Offering perspectives on the problems on the Mexican agenda, the authors discuss the politics of change, the challenges of social development, and how to build a mutually beneficial US-Mexico relationship.
"Rather than favoring only one approach, Juan J. Morrone proposes a comprehensive treatment of the developments and theories of evolutionary biogeography. Evolutionary biogeography uses distributional, phylogenetic, molecular, and fossil data to assess the historical changes that have produced current biotic patterns. Panbiogeography, parsimony analysis of endemicity, cladistic biogeography, and phylogeography are the four recent and most common approaches. Many conceive of these methods as representing different "schools," but Morrone shows how each addresses different questions in the various steps of an evolutionary biogeographical analysis. Panbiogeography and parsimony analysis of endemicity are useful for identifying biotic components or areas of endemism. Cladistic biogeography uses phylogenetic data to determine the relationships between these biotic components. Further information on fossils, phylogeographic patterns, and molecular clocks can be incorporated to identify different cenocrons. Finally, available geological knowledge can help construct a geobiotic scenario that may explain how analyzed areas were put into contact and how the biotic components and cenocrons inhabiting them evolved. Morrone compares these methods and employs case studies to make it clear which is best for the question at hand. Set problems, discussion sections, and glossaries further enhance classroom use."--Publisher's description.
