Genera Orchidacearum Volume 6
This sixth and final volume in the Genera Orchidacearum series treats 140 genera in tribes Dendrobieae and Vandeae of the largest subfamily, Epidendroideae, including some of the showiest orchids often used in hybridizing.
世界上最老最老的生命
在过去十年里，艺术家蕾切尔·萨斯曼穿越从北极到美国莫哈维沙漠在内的五大洲来拍摄30种已经持续存在了2000年以上的极其罕见的古老生命。这些珍贵的老生命，每一个都是不可思议的奇迹，它们在世界的某个极端环境中历经上千年的时光幸存下来，完全超出了现代人想象的极限。然而，环境变迁和人类的活动使它们中的许多都处在濒危状态，甚至有两种已经“过早地猝死”。伴随着这些老生命的珍贵照片，作者讲述了她自己在全球追踪它们的探险故事，以及正在研究这些老生命及其生存环境的科学家们的深刻洞察。如此一来，这些老生命所透露出的独特信息既记录了过去，也呼吁我们采取保护行动，并且还预示了未来的变化。 萨斯曼本着强烈的环保意识而开启自己的全球生态之旅，她的工作既是永恒的，又是及时的，而本书则成功地跨越了学科、空间和时间，成为环境探究的人文表达。任何看过本书的人士都会为那些老生命的美和生命力所震撼，进而自觉思考人类的命运和我们星球的命运。
Ecophysiological Analysis of Vulnerability to Climate Warming in Ectotherms
Temperature plays a critical role in animal survival and climate warming is one of the greatest threats to global biodiversity in the future. It is already affecting species and communities with severe impacts and it is predicted that climate warming will cause species extinctions and distributional shifts in the coming decades. The impact of climate warming is expected to be particularly severe on ectothermic animals, including fishes, amphibians, and reptiles. Thus, assessing species’ responses to ongoing climate warming and determining what conservation actions should be taken are among the most significant and controversial challenges for ecologists. Identifying the most vulnerable spe...

Climate Change Risk Profile of the Mountain Region in Sri Lanka
This publication studies the potential impact of climate change on Sri Lanka’s vulnerable mountain ecosystem in order to help guide sustainable adaptation strategies. It uses a mix of geographic information system mapping combined with average and projected rainfall figures to show how the mountains that make up 15% of Sri Lanka could be affected. Including a series of maps, the publication illustrates how the area faces rising drought alongside increasingly severe monsoons that could cause more floods and landslides. By showing the potential impact of climate change, it aims to help assess both future investments and strategies to cut disaster risk and enhance environmental sustainability in the biodiverse area.
Green Equilibrium
How do ecological and evolutionary factors maintain the balance of diverse species (including humans) in an ecosystem? With examples ranging from Bhutan to California, Christopher Wills explains the processes. He also presents striking evidence that human populations have adapted genetically to environments.
The Book of Orchids
One of every seven flowering plants on earth is an orchid. Some are stunningly over the top; others almost inconspicuous. The Orchidaceae is the second most widely geographically distributed family, after the grasses, yet remains one of the least understood. This book will profile 600 species, representing the remarkable and unexpected diversity and complexity in the taxonomy and phylogeny of these beguiling plants, and the extraordinary means they have evolved in order to ensure the attraction of pollinators. Each species entry includes life-size photographs to capture botanical detail, as well as information on distribution, peak flowering period, and unique attributes--both natural and cultural. The result is a work which will attract and allure, much as the orchids themselves do.
Biodiversity Hotspot of the Western Ghats and Sri Lanka
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.
Orchid Species from Himalaya and Southeast Asia Vol. 3 (R - Z)
A presentation of over 700 popular orchid species in 104 genera carefully detailed with beautiful photographs and concise descriptions of plants, their distribution and habitats by a well-known author and photographer. Each genus is assigned a separate chapter. Coverage of the most commonly cultivated Asian species including their varieties and cultivars (e.g. in Bulbophyllum 72 species; Coelogyne 33 species; Dendrobium 161 species; Paphiopedilum 58 species; Phalaenopsis 60 species; Vanda 44 species) is exhaustive. The orchids are photographed from their best perspective, individual blooms and entire inflorescence: additionally, many species are also shown growing in their natural habitat. R...
Medicinal Orchids of Asia
This unique book brings together a wealth of data on the botanical, ethno-medicinal and pharmacological aspects of over 500 species of Asian medicinal orchids. It starts off by explaining the role and limitations of complimentary and herbal medicines, and how traditional Asian medicine differs from Western, “scientific” medicine. The different Asian medical traditions are described, as well as their modes of preparing herbal remedies. The core of the book presents individual medicinal orchid species arranged by genera. Each species is identified by its official botanical name, synonyms, and local names. Its distribution, habitat and flowering season, uses and pharmacology are described. An overview sums up the research findings on all species within each genus. Clinical observations are discussed whenever available, and possible therapeutic applications are highlighted. The book closes with chapters on the conservation of medicinal orchids and on the role of randomized clinical trials.
