The preeminent naturalists Albert Hazen Wright and Anna Allen Wright spent years assembling the wealth of material on frogs and toads appearing in this widely used handbook, the third edition of which was originally published in 1949. With abundant black-and-white photographs, colorful descriptions, journal notes from the field, and excerpts from the literature, their personalized natural history emphasizes amphibians observed in the wild. In a foreword to the 1995 paperback edition, Roy McDiarmid, a foremost specialist on frogs and toads, brings the book into historical perspective and supplies information to bring it up to date. Accounts of more than 100 species and subspecies cover such topics as common and scientific names, range, habitat, size, and general appearance, as well as color, structure, voice, and breeding. Separate keys are given for secondary sexual characteristics, eggs, tadpoles, families, and species. Generous quotations from the Wrights' field journals give the reader a sense of the problems and satisfactions of their work.

This is the most authoritative and engaging philosophical reference work in English. It gives clear and reliable guidance to all areas of philosophy and to the ideas of all notable philosophers from antiquity to the present day. The scope of the volume is not limited to English-languagephilosophy: it surveys the foremost philosophy from all parts of the world. A distinguished international assembly of more than two hundred contributors provide almost 2,000 alphabetically arranged entries which are not only instructive but also entertaining: they combine learning, lucidity, elegance, and wit. There are more than fifty extended entries of 3,000 words on themain areas of philosophy and the great philosophers: these include essays by Alasdair MacIntyre on the history of moral philosophy, Paul Feyerabend on the history of the philosophy of science, Jaegwon Kim on problems of the philosophy of mind, Richard Swinburne on problems of the philosophy ofreligion, David Charles on Aristotle, Peter Singer on Hegel, Anthony Kenny on Frege, and Anthony Quinton on philosophy itself. Short entries deal with key concepts (for instance, personal identity, time) doctrines (utilitarianism, holism), problems (the mind-body problem, the meaning of life), schools of thought (Marxist philosophy, the Vienna Circle), and practical issues (abortion, vegetarianism). Individual thinkerspast (Pythagoras, Confucius, Galileo, Goethe, Burke, Santayana, de Beauvoir, Radhakrishnan) and present (over 150 contemporary figures, such as Chomsky, Derrida, and Popper) are profiled, and eighty of them are depicted in black-and-white portraits. Interspersed throughout are short explanations ofparticular philosophical terms (qualia, supervenience, iff), puzzles (the Achilles paradox, the prisoner's dilemma), and curiosities (the philosopher's stone, slime). Every entry is accompanied by suggestions for further reading. A chronological chart of the history of philosophy is located at theend of the book, together with fourteen diagrams showing the structure of philosophy and the relations between its subjects and doctrines. This book will be an indispensable guide and a constant source of stimulation and enlightenment for anyone interested in abstract thought, the eternal questions, and the foundations of human understanding.

Located in the heart of the Eastern Himalayas, Bhutan practices the philosophy of Gross National Happiness (“GNH”) that embraces environmental conservation as one of the main building blocks for its sustainable development goals. Bhutan’s conservation strategies and success are largely driven by the strong political will and visionary leadership of His Majesty the King of Bhutan The nation’s Buddhist perspectives regarding a deep and abiding respect for nature; and the strategic enforcement of a wide-ranging stringent set of internal regulations and controls have helped ensure ecological gold standards in Bhutan. Moreover, the country is an active member of the international conservation community by fulfilling its implementation of various Multilateral Environment Agreements. While it emerged into the 21st century as one of the 36 global terrestrial “hotspots” in biological diversity conservation ranks, Bhutan’s sheer commitment with more than 51% of its territory being managed under the explicit status of a protected area network, and more than 70% of the land under forest cover, represents Bhutan’s exemplary dedication to protect the planet despite its smallness in size and economy, and the biological fragility exemplified by its hotspot situation. In the face of imminent severe threats of global warming, Bhutan nonetheless exemplifies the truth that “a small country with a big conservation commitment” can make an enormous contribution to the global community. At the regional level, Bhutan is intent upon protecting the Water Towers of Asia (that glacial expanse of the Himalayas) which is a critical resource bulwark for about one-fifth of the global population downstream in South Asia. Such protections invariably help mitigate climate change by acting as a nation-wide carbon sink through its carbon neutral policies. In short, Bhutan has long represented one of the world’s foremost national guardians of biodiversity conservation, ecological good governance, and societal sustainability at a period when the world has entered the Anthropocene – an epoch of mass extinctions. We envision this publication to be ecologically and ethically provocative and revealing for the concerned scientific communities, and governments. Through an extensive review of the scientific and anthropological literature, as well as the research team's own data, the Author's have set forth timely recommendations for conservation policies, strategies and actions. This book provides technical and deeply considered assessments of the state of Bhutan’s environment, its multiple, human-induced stressors and pressures; as well as extremely sound, practical techniques that would address conservation strategies in the Himalayas and, by implication, worldwide.
