Conservation Biology for All provides cutting-edge but basic conservation science to a global readership. A series of authoritative chapters have been written by the top names in conservation biology with the principal aim of disseminating cutting-edge conservation knowledge as widely as possible. Important topics such as balancing conversion and human needs, climate change, conservation planning, designing and analyzing conservation research, ecosystem services, endangered species management, extinctions, fire, habitat loss, and invasive species are covered. Numerous textboxes describing additional relevant material or case studies are also included. The global biodiversity crisis is now unstoppable; what can be saved in the developing world will require an educated constituency in both the developing and developed world. Habitat loss is particularly acute in developing countries, which is of special concern because it tends to be these locations where the greatest species diversity and richest centres of endemism are to be found. Sadly, developing world conservation scientists have found it difficult to access an authoritative textbook, which is particularly ironic since it is these countries where the potential benefits of knowledge application are greatest. There is now an urgent need to educate the next generation of scientists in developing countries, so that they are in a better position to protect their natural resources.

There is a common belief that until recently Americans have preferred isolation to interest in remote areas such as Southeast Asia. This thesis can be tested by examining the history of American relations with a place on the opposite side of the globe from the United States. Such a land is Sumatra. It is one of the largest islands in the world. Its I66,789 square mile area exceeds that of the third largest American state, California, and is larger than Italy. Lying halfway around the world from the United States, its I050 mile length is almost divided by the equator, which runs across it for 285 miles. Sumatra's strategic importance is two-fold. Firstly, it is the first island stepping stone from the Asiatic mainland into the Australasian archipelago. This was demonstrated in I942 when the United States stationed planes on Sumatra in an attempt to stem the Japanese advance southward. Secondly, it lies athwart the shortest sea routes from Eastern Asia to Europe and the Eastern United States. Sumatra's southern tip forms one side of the Straits of Sunda which guards the access to the Java, China and Philippine Seas. At the island's northern tip is the entrance to the Straits of Malacca, the shortest sea lane be tween the Near and Far East. The opening of the Suez Canal in I869 shifted the shortest route between the Far East and the Western World from the Sunda to the Malacca Straits.

This book sheds new light on the role of various environmental factors in regulating the metabolic adaptation of medicinal and aromatic plants. Many of the chapters present cutting-edge findings on the contamination of medicinal plants through horizontal transfer, as well as nanomaterials and the biosynthesis of pharmacologically active compounds. In addition, the book highlights the impacts of environmental factors (e.g., high and low temperature, climate change, global warming, UV irradiation, intense sunlight and shade, ozone, carbon dioxide, drought, salinity, nutrient deficiency, agrochemicals, waste, heavy metals, nanomaterials, weeds, pests and pathogen infections) on medicinal and aromatic plants, emphasizing secondary metabolisms. In recent years, interest has grown in the use of bioactive compounds from natural sources. Medicinal and aromatic plants constitute an important part of the natural environment and agro-ecosystems, and contain a wealth of chemical compounds known as secondary metabolites and including alkaloids, glycosides, essential oils and other miscellaneous active substances. These metabolites help plants cope with environmental and/or external stimuli in a rapid, reversible and ecologically meaningful manner. Additionally, environmental factors play a crucial role in regulating the metabolic yield of these biologically active molecules. Understanding how medicinal plants respond to environmental perturbations and climate change could open new frontiers in plant production and in agriculture, where successive innovation is urgently needed due to the looming challenges in connection with global food security and climate change. Readers will discover a range of revealing perspectives and the latest research on this vital topic.

The Academy of Natural Sciences of Philadelphia is home to more than 200 priceless specimens of plants collected by Meriwether Lewis and William Clark on their historic journey from 1803-1806 through what would become the western part of the United States. The dried and pressed plants housed in the Academy are virtually all that remains of the physical specimens brought back by the two explorers. These plants are historic treasures from an age in exploration and national growth that dramatically changed the United States. But they are more than museum pieces--the specimens are also scientific treasures to modern researchers studying the flora of North America.
