Book Description
Biodiversity is declining at an alarming rate due to anthropogenic activities around the world. This book is the first volume in the new series Biodiversity Hotspots of the World, which highlights the 36 hotspot regions of the world, regions that were designated as reaping maximum benefit from preservation efforts. This series is our humble attempt to document these hotspots as a conservation and preservation measure. This first volume in the series focuses on the Western Ghats and Sri Lanka, construed as forming a community of species because of their shared biogeographical history. The volume explores the diversity and conservation efforts of the extraordinarily rich species found here, including plants, many of which are found nowhere else in the world; forests, which face tremendous population pressure and have been dramatically impacted by demands for timber and agricultural land; as well as the hotspot’s diverse mammals, birds, insects, and amphibian species, and more. The volumes in this series will be essential resources for researchers and practitioners in the fields of conservation biology, ecology, and evolution.

Book Description
Bryophytes are of great importance in their ecosystems and for human well-being. They stabilize soil crust through colonization of bare grounds and rocks; they are essential in nutrient recycling, biomass production, and carbon fixing; they control water through an effective retention mechanism; and they have economic value as peat for fuel, horticulture, oil absorption, and as sources of a wide variety of chemical compounds. Bryophytes have long been used for medicinal purposes and provide a food source for reindeer, geese, ducks, sheep, musk-ox, lemmings, and other rodents. Threats include deforestation, cultivation of forests, reclamation of land, urbanization, roads, dam-building, mining, drainage of wetlands and over-grazing. This plan reviews the situation worldwide and proposes a variety of initiatives. It is aimed at those who work with and care about nature conservation, including governmental and non-governmental organizations as well as politicians and the general interested public.

Book Description
Early anthropological evidence for plant use as medicine is 60,000 years old as reported from the Neanderthal grave in Iraq. The importance of plants as medicine is further supported by archeological evidence from Asia and the Middle East. Today, around 1.4 billion people in South Asia alone have no access to modern health care, and rely instead on traditional medicine to alleviate various symptoms. On a global basis, approximately 50 to 80 thousand plant species are used either natively or as pharmaceutical derivatives for life-threatening conditions that include diabetes, hypertension and cancers. As the demand for plant-based medicine rises, there is an unmet need to investigate the quality, safety and efficacy of these herbals by the “scientific methods”. Current research on drug discovery from medicinal plants involves a multifaceted approach combining botanical, phytochemical, analytical, and molecular techniques. For instance, high throughput robotic screens have been developed by industry; it is now possible to carry out 50,000 tests per day in the search for compounds, which act on a key enzyme or a subset of receptors. This and other bioassays thus offer hope that one may eventually identify compounds for treating a variety of diseases or conditions. However, drug development from natural products is not without its problems. Frequent challenges encountered include the procurement of raw materials, the selection and implementation of appropriate high-throughput bioassays, and the scaling-up of preparative procedures. Research scientists should therefore arm themselves with the right tools and knowledge in order to harness the vast potentials of plant-based therapeutics. The main objective of Plant and Human Health is to serve as a comprehensive guide for this endeavor. Volume 1 highlights how humans from specific areas or cultures use indigenous plants. Despite technological developments, herbal drugs still occupy a preferential place in a majority of the population in the third world and have slowly taken roots as alternative medicine in the West. The integration of modern science with traditional uses of herbal drugs is important for our understanding of this ethnobotanical relationship. Volume 2 deals with the phytochemical and molecular characterization of herbal medicine. Specifically, it focuess on the secondary metabolic compounds, which afford protection against diseases. Lastly, Volume 3 discusses the physiological mechanisms by which the active ingredients of medicinal plants serve to improve human health. Together this three-volume collection intends to bridge the gap for herbalists, traditional and modern medical practitioners, and students and researchers in botany and horticulture.

Book Description
Biodiversity is declining at an alarming rate due to anthropogenic activities around the world. This book is the second volume in the new series Biodiversity Hotspots of the World, which highlights the 36 hotspot regions of the world, regions that have been designated as reaping maximum benefit from preservation efforts. This series is our humble attempt to document these hotspots as a conservation and preservation measure. The concise volumes in this series focus on the most interesting and important properties of these hotspots, covering physiography and climatology; vegetation and forest types; amphibian and reptile biodiversity; genetic diversity of crops, plants, fishes, butterflies, insects, birds, mammals, angiosperms, and gymnosperms; and much more. And of course, the unique threats and conservation efforts for the areas are addressed as well. The Himalayan Mountains are the highest mountain range in the world and include Mount Everest as well as eight other highest peaks of the world. While it is difficult to document the biodiversity of this inhospitable terrain, we do know that out of the 9,000 different species of plants recorded in the area, 3,500 plants are endemic to the Eastern Himalaya region. Anthropogenic activities including deforestation, fragmentation of habitats, pollution, high population, climate change, and poaching of wildlife pose serious threats to the biodiversity of the region. The highlands have exceptionally rich biodiversity, high endemism, and over 160 globally threatened species, including the densest population of Bengal tigers and the three largest herbivores on the continent: the Asian elephant, greater one-horned rhinoceros, and wild water buffalo. The region boasts the world’s richest counts of alpine flora within its temperate broad-leaved forests, with a total of 10,000 species of plants. This volume, Biodiversity Hotspot of the Himalayas, as well as the other volumes in this series, will be essential resources for researchers and practitioners in the fields of conservation biology, ecology, and evolution as the series concisely records the existing biodiversity of these hotspots of the world.

Book Description
This reference work provides a comprehensive overview of bioactive compounds investigated in bryophytes and pteridophytes and explores their nutritional, biological, pharmacological and ecological effects. Bryophytes are cosmopolitan lower plants that are rich in phytochemicals including fatty acids, tocopherols, phenolics, terpenoids. Additionally, these plants contain bibenzyls, bis-benzyls, and polyketides which have been demonstrated to have antimicrobial, anti-inflammatory, and cytotoxic activities. Pteridophytes are another group of lower vascular plants which were reported to have useful secondary compounds such as flavonoids, steroids, phenolics, terpenoids, and these plants impart medicinal values including antioxidant, antimicrobial, anti-inflammatory, anti-tumor, and anti-HIV activities. This book contains comprehensive contributions compiled by expert scientists and researchers in this field.The book offers a useful resource for plant biotechnologists, plant biologists, pharmacologists, pharmacists, food technologists, nutritionists, research investigators of the healthcare industry, academia, faculty, and students of biology and biomedical sciences.

Book Description
The Himalaya, a global biodiversity hotspot, sustains about one-fifth of the humankind. Nestled within the north-western mountain ranges of the Himalaya, the Jammu and Kashmir (J&K) State harbours more than half of the biodiversity found in the Indian Himalaya. The wide expanse of State, spread across the subtropical Jammu, through the temperate Kashmir valley, to the cold arid Ladakh, is typical representative of the extensive elevational and topographical diversity encountered in the entire Himalaya. This book, the most comprehensive and updated synthesis ever made available on biodiversity of the J&K State, is a valuable addition to the biodiversity literature with global and regional relevance. The book, arranged into 7 parts, comprises of 42 chapters contributed by 87 researchers, each of whom is an expert in his/her own field of research. The precious baseline data contained in the book would form the foundation for assessing current status of knowledge about the bioresources, identify the knowledge gaps, and help prioritization of conservation strategies to steer the sustainable use of biodiversity in this Himalayan region. Given the breadth of topics covered under the banner of biodiversity in this book, it can surely serve as a model for documentation of biodiversity in other regions of the world. The book will be of immense value to all those who, directly or indirectly, have to deal with biodiversity, including students, teachers, researchers, naturalists, environmentalists, resource managers, planners, government agencies, NGOs and the general public at large.
