Big-Leaf Mahogany is the most important commercial timber species of the tropics. Current debate concerning whether to protect it as an endangered species has been hampered by the lack of complete, definitive scientific documentation. This book reports on vital research on the ecology of big-leaf mahogany, including genetic variations, regeneration, natural distribution patterns and the silvicutural and trade implications for the tree.
The aim of this book is to improve the understanding of forest dynamics and the sustainable management of forest ecosystems. How do tree crowns, trees or entire forest stands respond to thinning in the long term? What effect do tree species mixtures and multi-layering have on the productivity and stability of trees, stands or forest enterprises? How do tree and stand growth respond to stress factors such as climate change or air pollution? Furthermore, in the event that one has acquired knowledge about the effects of thinning, mixture and stress, how can one make that knowledge applicable to decision-making in forestry practice? The experimental designs, analytical methods, general relationships and models for answering questions of this kind are the focus of this book. Given the structures dealt with, which range from plant organs to the tree, stand and enterprise levels, and the processes analysed in a time frame of days or months to decades or even centuries, this book is directed at all readers interested in trees, forest stands and forest ecosystems. This work has been compiled for students, scientists, lecturers, forest planners, forest managers, and consultants.
Decision Methods for Forest Resource Management focuses on decision making for forests that are managed for both ecological and economic objectives. The essential modern decision methods used in the scientific management of forests are described using basic algebra, computer spreadsheets, and numerous examples and applications. Balanced treatment is given throughout the book to the ecological and economic impacts of alternative management decisions in both even-aged and uneven-aged forests. In-depth coverage of both ecological and economic issues Hands-on examples with Excel spreadsheets; electronic versions available on the authors' website Many related exercises with solutions Instructor's Manual available upon request
This book constitutes the refereed proceedings of the First GIS LATAM Conference, GIS LATAM 2020, held in September 2020. Due to the COVID-19 pandemic the conference was held online. The 9 full papers and 2 short papers were thoroughly reviewed and selected from 29 submissions. The papers are focused on the GIS applications in data analytics in spheres of health, environment, government, public, and education.
The Declaration of Independence is one of the most influential documents in modern history-the inspiration for what would become the most powerful democracy in the world. Indeed, at every stage of American history, the Declaration has been a touchstone for evaluating the legitimacy of legal, social, and political practices. Not only have civil rights activists drawn inspiration from its proclamation of inalienable rights, but individuals decrying a wide variety of governmental abuses have turned for support to the document's enumeration of British tyranny. In this sweeping synthesis of the Declaration's impact on American life, ranging from 1776 to the present, Alexander Tsesis offers a deeply researched narrative that highlights the many surprising ways in which this document has influenced American politics, law, and society. The drafting of the Bill of Rights, the Reconstruction Amendments, the New Deal, the Civil Rights movement-all are heavily indebted to the Declaration's principles of representative government. Tsesis demonstrates that from the founding on, the Declaration has played a central role in American political and social advocacy, congressional debates, and presidential decisions. He focuses on how successive generations internalized, adapted, and interpreted its meaning, but he also shines a light on the many American failures to live up to the ideals enshrined in the document. Based on extensive research from primary sources such as newspapers, diaries, letters, transcripts of speeches, and congressional records, For Liberty and Equality shows how our founding document shaped America through successive eras and why its influence has always been crucial to the nation and our way of life.
