Challenges and Opportunities in Orchid Ecology and Conservation by Pavel Kindlmann,Tiiu Kull,Dennis Whigham Pdf

Understanding diversity patterns and the effect of global change on abundance, distribution patterns and species survival are of the most discussed topics in biodiversity research. Species are disappearing worldwide, mostly due to habitat loss, but other factors like climate change are likely to increase in importance during the 21st century. Thus, one of the most worrying issues is that we still do not know the optimal abiotic and biotic requirements for population persistence of many of the still existing species, which makes it very difficult, if not impossible, to make appropriate recommendations for their conservation in terms of proposing an effective management of their sites. Analysis of these requirements is, however, strongly dependent on the taxonomic group considered and on life history strategies of the species that comprise the group. In this Research Topic, we concentrate on this issue applied to orchids, one of the most abundant groups of flowering plants with approximately 30,000 species. They are classified among the most threatened groups worldwide. Of the approximately 1000 species that have been evaluated, almost 60% are threatened, endangered or extinct. For a few orchid species, detailed records from monitoring efforts provide opportunities for comparative analyses of species declines through time. However, for most orchid species we still lack population data and there have been few studies that have focused on the environmental factors and species traits associated with the decline of orchid sites and species numbers.

Orchid Biology: Recent Trends & Challenges by Shaik Mahammad Khasim,Sadanand Nagesh Hegde,María Teresa González-Arnao,Kanchit Thammasiri Pdf

This book on “Orchid Biology: Recent Trends & Challenges” reviews the latest strategies for the preservation and conservation of orchid diversity and orchid germplasm. It is an outcome of the Proceedings of the International Symposium on “Biodiversity of Medicinal Plants & Orchids: Emerging Trends and Challenges” held on 9-11 February 2018 at Acharya Nagarjuna University, India. In addition, eminent orchid experts from around the globe were invited to contribute to this book. All chapters were peer-reviewed by international experts. The Orchidaceae are one of the largest families of flowering plants, comprising over 700 genera and 22,500 species and contributing roughly 40 percent of monocotyledons. They also represent the second-largest flowering plant family in India, with 1,141 species in 166 genera, and contribute roughly 10% of Indian flora. Orchids comprise a unique group of plants and their flowers are among the most enchanting and exquisite creations of nature. Phylogenetically and taxonomically, the Orchidaceae are considered to be a highly evolved family among angiosperms. They show incredible diversity in terms of the shape, size and colour of their flowers, and are of great commercial importance in floriculture markets around the globe. Millions of cut flowers of Cymbidium, Dendrobium, Cattleya, Paphiopedilum, Phalaenopsis, Vanda etc., besides potted orchid plants, are sold in Western Countries and thus, the orchid cut flower industry has now become a multimillion-dollar business in Europe, the USA and South East Asia. Besides their ornamental value, orchids hold tremendous pharmaceutical potential. Root tubers of Habenaria edgeworthii form an important component of the ‘Astavarga’ group of drugs in Ayurvedic medicine. It is an established fact that tubers of some terrestrial orchids have been used to treat diarrhoea, dysentery, intestinal disorders, cough, cold and tuberculosis. Some orchids, particularly those belonging to the genera Aerides, Arachnis, Cattleya, Cymbidium, Dendrobium, Epidendrum, Oncidium, Paphiopedilum, Phalaenopsis, Renanthera, Vanda etc. have been extensively used to produce internationally acclaimed hybrids. Yet paradoxically, Indian orchids are victims of their own beauty and popularity. As a result, their natural populations have been declining rapidly because of unbridled commercial exploitation in India and abroad. In fact, some orchids are now at the verge of extinction, e.g. Renanthera imschootiana, Diplomeris hirsuta, Paphiopedilum fairrieanum, Cypripedium elegans, Taeniophylum andamanicum etc. Given the global importance of orchids in terms of securing human health and wealth, this comprehensive compilation, prepared by international experts, is highly topical. Its content is divided into five main sections: (I) Cryopreservation & Biotechnology, (II) Orchid Biodiversity & Conservation, (III) Anatomy & Physiology, (IV) Pollination Biology and (V) Orchid Chemicals & Bioactive Compounds. All contributions were written by eminent orchid experts/professors from around the world, making the book a valuable reference guide for all researchers, teachers, orchid enthusiasts, orchid growers and students of biotechnology, botany, pharmaceutical sciences and ethnomedicine. It will be equally valuable for readers from the horticultural industry, especially the orchid industry, agricultural scientists and policymakers.

Orchid Biology: Reviews and Perspectives X by Tiiu Kull,J. Arditti,Sek Man Wong Pdf

As stated many times before the purpose of Orchid Biology, Reviews and Perspectives (OB) is to present reviews on all aspects of orchids. The aim is not to balance every volume, but to make a balanced and wide ranging presentation of orchids in the series as a whole. The chapters in this, the last volume of the series, range over a number of topics which were not covered before. Singapore is justly famed for its orchids. They can be seen on arrival (or dep- ture) in its modern, highly efficient and comfortable Changi Airport and on the way from it to town. Vanda Miss Joaquim, the first hybrid to come from Singapore became its National Flower. This natural hybrid can be seen on its currency, stamps, and public and private decorations. Many excellent breeders, starting with Prof. Eric Holttum who bred the first man made hybrid (Spathoglottis Primrose), produced numerous magnificent hybrids and won countless awards in Singapore and elsewhere. These hybrids served to enrich the country’s orchid mystique. In the opening chapter of this volume Dr. Teoh Eng Soon (Western style: Eng Soon Teoh), himself a prize winning orchid breeder, grower and author writes about some of the breeders who contributed to the Singapore orchid fame. Prof. Hans Fitting was one of the best known plant physiologists of his time. As a young man he studied the effects of pollen on orchid flowers.

Orchids by Henrik Aerenlund Pedersen Pdf

A beautiful, richly illustrated book on Europe's wild orchids - perhaps the most enigmatic and popular group in the botanical world. The orchid family (Orchidaceae), numbering some 25,000 species, is one of the world's two largest families of flowering plants. Whilst the vast majority of orchids are found in the wet tropics, Europe accommodates c.130 native orchid species which are equally arranged in dense inflorescences of great beauty. Furthermore, the adaptations encountered in some of the European species are just as fascinating as those of their tropical relatives. This book provides an introduction to the native orchids of Europe. It features four sections: 'Structure and systematics', 'Orchids and the environment', 'Orchid portraits' and 'How to learn more'. This part constitutes the bulk of the book, presenting individual genera in a sequence which reflects their most likely evolutionary relationships. Each genus is introduced by one page of text and illustrated by one or more colour plates on the following pages. The text gives information on how to recognise the genus, where it is distributed, and the estimated number of species it contains - alongside information on the range of environmental requirements and flowering times in the European species. Depending on the genus, additional information may be found on topics such as pollination biology, associated fungi, evolutionary relationships or systematic problems. Beautiful watercolour artwork accompanies the text, making this an indispensable gift for anyone interested in the natural world. Not only is it a useful field guide, it is also a beautiful art book.

Orchids of Tropical America by Joe E. Meisel,Ronald S. Kaufmann,Franco Pupulin Pdf

Orchids of Tropical America is an entertaining, informative, and splendidly illustrated introduction to the orchid family for enthusiasts and newcomers seeking to learn about more than 120 widespread orchid genera. Joe E. Meisel, Ronald S. Kaufmann, and Franco Pupulin bring alive the riot of colors, extraordinary shapes, and varied biology and ecology of the principal orchid genera ranging from Mexico and the Caribbean to Bolivia and Brazil. Orchids, likely the most diverse family of plants on earth, reach their peak diversity in the tropical countries of the Western Hemisphere, including, for example, more than 2,500 species in Brazil and 4,000 in Ecuador. The book also highlights reserves in the American tropics where travelers can enjoy orchids in the wild. Whether you journey abroad to see these unique plants, raise them in your home, or admire them from afar, this book offers fascinating insights into the diversity and natural history of orchids. Beyond the plant and flower descriptions, Orchids of Tropical America is packed with informative stories about the ecology and history of each genus. Pollination ecology is given in detail, with an emphasis on how floral features distinctive to the genus are linked to interaction with pollinators. This book also features information on medicinal and commercial uses, notes on the discoverers, and relevant historical data. The easy-to-use identification system permits quick recognition of the most common orchid groups in Central and South America. Genus descriptions are given in plain language designed for a nonscientific audience but will prove highly useful to advanced botanists as well. Descriptions focus on external morphology, and great care has been taken to ensure the guide is useful in the field without reliance on microscopes or dissections. Equally valuable as a field guide, a desktop reference, or a gift, Orchids of Tropical America will make an excellent addition to any orchid lover’s library.
