Coral Reef Marine Plants of Hainan Island summarizes the literature on the role and use of marine plants in coral reef ecosystems, especially in China and countries in the Asia-Pacific Region. The first chapter of the book focuses on the description of coral reef ecosystems, their architecture, and status of Hainan coral reefs. The second chapter focuses on common knowledge surrounding marine plants, such as their classification, identifying characteristics of different phyla, morphology, reproduction, life forms, main algal communities on coral reefs, distribution of algae on coral reefs and their roles, and the use of seaweeds in cookery, medicine, industry, and agriculture. The third chapter on the seaweed flora of Hainan Island contains species composition of the marine benthic flora, the complete list of marine plants found by researchers from all studies, and historical changes in the flora and seasonal changes. The final chapter shows how to identify common species of marine plants on coral reefs of Hainan Island. This excellent work will help readers identify relevant plants, also teaching them how to use plant resources to assess endangered states and create conservation strategies. - Presents the first publication devoted to the description of marine plants of Hainan Island - Describes marine plants, including the role of their communities in ecosystems of coral reef - Discusses seasonal and decadal changes in biodiversity and the composition of the marine flora of the island - Combines fundamental morphology with utilization and related products
NATIONAL BESTSELLER • "James and Deborah Fallows have always moved to where history is being made.... They have an excellent sense of where world-shaping events are taking place at any moment" —The New York Times • The basis for the HBO documentary streaming on HBO Max For five years, James and Deborah Fallows have travelled across America in a single-engine prop airplane. Visiting dozens of towns, the America they saw is acutely conscious of its problems—from economic dislocation to the opioid scourge—but it is also crafting solutions, with a practical-minded determination at dramatic odds with the bitter paralysis of national politics. At times of dysfunction on a national level, reform possibilities have often arisen from the local level. The Fallowses describe America in the middle of one of these creative waves. Their view of the country is as complex and contradictory as America itself, but it also reflects the energy, the generosity and compassion, the dreams, and the determination of many who are in the midst of making things better. Our Towns is the story of their journey—and an account of a country busy remaking itself.
This book discusses how and why historical measurement units developed, and reviews useful methods for making conversions as well as situations in which dimensional analysis can be used. It starts from the history of length measurement, which is one of the oldest measures used by humans. It highlights the importance of area measurement, briefly discussing the methods for determining areas mathematically and by measurement. The book continues on to detail the development of measures for volume, mass, weight, time, temperature, angle, electrical units, amounts of substances, and light intensity. The seven SI/metric base units are highlighted, as well as a number of other units that have historically been used as base units. Providing a comprehensive reference for interconversion among the commonly measured quantities in the different measurement systems with engineering accuracy, it also examines the relationships among base units in fields such as mechanical/thermal, electromagnetic and physical flow rates and fluxes using diagrams.
Includes reports on population, housing, agriculture, industry, education, employment, commerce, geography, territories and possessions, vital statistics and life tables.
